Down Bits (Down Cut) And CNC Routers [What You Didn't Know] - Garrett Fromme

[@davidpinson9403]

Wow, there was a time when all of this seemed a mystery to me. However, since watching your videos, you have taken the mystery out of cncing. Thank you so much for all your help

[@davidpinson9403]

What to set up a one on one. How do I do that and what is the cost?

[@IDCWoodcraft]

DavidPinson, congrats and welcome to the wonderful world of CNC brother!

[@IDCWoodcraft]

David, I am sorry brother but I have not had time to do one-on-ones lately. You can set one up with a sister CNCer Kate, here is the link: idcwoodcraft.com/pages/cnc-router-one-on-one-help

[@jackwelch480]

You didn't just explain how to fix it - but explained why it was occurring. I appreciate that.

[@IDCWoodcraft]

jackwelch480, I'm so glad you found the explanation helpful! Understanding the "why" can really make a difference in troubleshooting.

[@HemiDad1963]

I never would have believed that the router bit could climb up like that. Thank you for educating me.

[@IDCWoodcraft]

Hey Don. It's one of those things learned after many years of experience.

[@guyrivard8613]

Garrett, The addition of the last "clean-up" pass feeds my OCD to new levels. It is what gives the project a quality appearance and would heighten the actual value of that project. Thankew ! - - - GR 13 Aug '21

[@IDCWoodcraft]

Hey Guy. You are so right. The finish makes so much difference and by doing a finish pass, it gives it a much better look.

[@lippa618papalee4]

your information is spot on as always Garrett you explain things in a way that even I can understand everything you say!!! I am a brand new future CNC student and loving it!! Thank you for helping understand how everything works together.

[@IDCWoodcraft]

lippa618papalee4, you are so welcome my friend. Happy CNCing.

[@wrapssignsandgraphics2019]

I’ve been running a cnc for over 20 years and I am very impressed with your content! Love the downcut information! Just ordered a few new downs! Thanks again

[@IDCWoodcraft]

Wraps Signs and Graphics, awesome thank you! I'm sorry for the delayed response, it's been a busy week working on getting out some new content this week!

[@onedozenwhickedwords]

Following your channel as Im just looking into buying a cnc router, so bagging as much information as i can 👍 Great channel with good information thanks 👍

[@IDCWoodcraft]

Hi Gaz. Thank you for complimenting. And welcome aboard!

[@jasonfellows5610]

lightbulb moment...so obvious when explained so well.....keep up good work

[@IDCWoodcraft]

Thanks Jason!!

[@paulwheeler6676]

I just finished a sign for my cousin for a wedding present. I had a lot of sanding that I did to make it flat. I wished I would of watch this before I started I could of saved a lot of time, thank you.

[@IDCWoodcraft]

Paul, sorry this one didn't quite find you in time for the sign! Hopefully it will come in handy on the next one though brother! Happy cutting!

[@saighusa]

I've been CNC routing for a few years. No one explained this problem until now. Many thanks!

[@IDCWoodcraft]

Saighusa, you are so welcome my friend.

[@kevinleemedlin385]

I don't even have my CNC yet, but I can already tell that THIS IS AWESOME INFO HERE! I'm sure this will come up, and now I have a head start on being able to address it--maybe even before it happens! Thanks! (From a fellow Jeep guy!)

[@IDCWoodcraft]

Kevin, you will know what to do to almost stop this from happening completely now!

[@RattlecanGuitarRestorations]

Absolutely brilliant explanation of what is going on. This video should come in a little box with every CNC router. Well done Garrett!

[@IDCWoodcraft]

RattlecanGuitarRestorations, you are so welcome brother.

[@EpicPovAction]

I’ve needed to see this video 10 years ago. So much time not sanding I’ll save now!

[@IDCWoodcraft]

EpicPovAction, I'm glad you found the video helpful! Sanding is one of those tasks that can make a big difference in the final outcome of your project. Happy woodworking!

[@cjtoledor]

Running a second pass makes all the sense in the world ! Then you showed the machine in action ! Final results awesome !😎😎🤙🤙👌👌

[@IDCWoodcraft]

Cjtoledor, glad to hear that you had your "aha" moment with the second pass. And you are totally right, the machine in action with the final results make for an awesome finished project.

[@COLJimC]

Thanks, the tiny final pass will help me greatly! I've spent hours cleaning the bottom of pocket areas to meet my standards.

[@IDCWoodcraft]

Jim, that is great to hear my friend. Makes your life a whole lot easier doesn't it?

[@BHWoodcrafters]

WOW!! I've had this problem for almost two years now. I didn't know what a final pass was or how to do it. You never seem to impress me with your videos , this one if from two years ago and I am just now seeing it. A couple of cups of coffee is coming your way my friend,

[@IDCWoodcraft]

BHWoodcrafters, right on brother! So happy to hear this one helped you.

[@alwayscensored6871]

Discovering why my upcut cuts deeper than I thought. Down cut and finishing pass makes lots of sense.

[@IDCWoodcraft]

Always Censored, glad this video helped you brother. Its amazing how much a small change to a bit can make such a big difference isnt it?

[@Checkitfirst]

I’m a beginner and I just learned from you a a bit of knowledge that I probably wouldn’t have never learned. Thank you 😊

[@IDCWoodcraft]

Check it first, you are so welcome my friend.

[@1powelrainbow2]

I'm new to CNC (haven't bought mine just yet) and just discovered your videos and I'm so happy I did! Even though I have done some reading into it, so many of your videos have given me so much more. Subscribed!

[@IDCWoodcraft]

1powelrainbow, welcome to the wonderful world of CNC. Happy to have you here.

[@GyWO10]

Wow, thank you for producing this video because I ruin 3 attempts at making a house warming gift for a friend because it left obvious level differences. I will certainly give this step a try!

[@IDCWoodcraft]

Dawayne, that can be frustrating for sure. Hopefully it turns out perfect this time!

[@craigmelvin4889]

Just made another bit order from you while learning more about Vectric. I never noticed the edit passes option. Thanks for another great tutorial

[@IDCWoodcraft]

Hi Craig. Your bit is on its way! There are so many little tools in vectric, it's hard to catch them all at once.

[@danielbarnes8908]

I am new to the CNC. I purchased my cnc about a year and half ago. I have had no one personally to show me anything about cnc work, so I have been watching youtube videos such as these to learn how to get better. Thanks for the great information!! The aha moment for me is when you explained the mechanics of the up cut and down cut bits. I have been struggling for a while with clean up on my projects, which can take alot of time depending on the size of the project. This video has been very informative and thanks for taking the time to put it on youtube. Looking forward to watching other videos.

[@IDCWoodcraft]

Daniel, I know that overwhelming feeling trying to figure everything out on your own! I'm glad you found the channel, we have an awesome community of CNC brothers and sisters here to lean on for support. I live for those aha moments, thanks for sharing.Hopefully cleaning up your projects won't be such a hassle from now on! Keep up the good work!

[@TheKirk48]

I learn so much from these videos, I can’t thank you enough.

[@IDCWoodcraft]

Steve, glad to help my friend!

[@chrisrobinson9540]

Hi just joined. This proves to me that what some (so called experts/experienced users) give advice on any particular problem often is a load of ____. I will soon be buying my first cnc (at long last) so now I will be starting out with, at least some good knowledge, and not fed a load of BS by people who don't know anything about it all. Thanks and please keep them coming!

[@IDCWoodcraft]

Hi Chris. Sorry for the delay in responding. I appreciate what you shared and I hope the videos I create for you and other CNC'ers will help you immensely!

[@bobburks4560]

AHA!!!! I had actually stopped doing some lettering due to marks and uneven levels that I got. Now I can do them knowing that I will get a great, smooth result and finish. Thanks for all your great advice and information.

[@IDCWoodcraft]

Bob, right on brother! Glad to hear this video set you on the right track.

[@therealclayharper]

This video resolved so many questions I've had for so long. THANK YOU!

[@IDCWoodcraft]

therealclayharper, I'm so glad to hear that! Enjoy your woodworking journey!

[@WindRidgeWoodCrafts]

Great info, Garrett. I've been doing something similar by using a pair of toolpaths, a roughing pass and a finishing pass, for the paths where this is needed/relevant. The roughing pass will typically stop 0.01 above the final depth. The finishing pass will take care of the final 0.01, as well as have a smaller stepover and a higher feed rate. For instance, the roughing pass might have a 0.1 DOC, a 25% stepover and a feed of 60 IPM. The finishing pass will be 0.01 DOC, 10% stepover and feed rate of 100 IPM. Yes, it takes longer, but still shorter time than cleaning up without the finishing pass.

[@IDCWoodcraft]

Excellent. You've got it figured out! It usually takes a painful journey of sanding and realising it is much more worth letting the machine spend extra time at it.

[@teamchiina7111]

I've been doing this since my first sign but I never really knew why, thanks for the mechanical breakdown!

[@IDCWoodcraft]

Teamchina, glad this one helped brother!

[@gregschlierf2931]

I always thought you would make the first pass with the Down Bit, then switch to up for the end. But this makes perfect sense. As always, Great video.

[@IDCWoodcraft]

Hi Greg. I didn't switch up, because I didn't need to. Although, it's not a bad idea if you want to take the extra step.

[@davidlefurge2946]

My growing CNC knowledge needed this tip, appreciate it Garret.

[@IDCWoodcraft]

davidlefurge2946, glad to hear it brother!

[@dennismcaleer242]

I’ve had this happen with v bits when I was making a Chicago Blackhawks carve. Thanks this helps a lot! I used to chisel and sand out the burrs, not anymore thanks to you!

[@IDCWoodcraft]

Hey Dennis. You will have much better results now that you know this!!!

[@jimscott64]

Thanks Garret, another good one!! I have noticed what you are showing and never knew there was a fix for that. I also have a question for you. I fall my own trees and have a friend with a Woodmizer saw mill who mills my logs for me. One of my favorite woods for simple not for show projects is Spruce. We can fall trees up to twenty four inches diameter with a wood cutting permit and in some areas even bigger. What I like most about it is that the bottom sections of the trees are almost knot free. I makes really nice clear lumber. And the best part is that it's free. Don't know if you have ever used it but I can tell you this, it is very, very strigy. In this video where you show the difference between the cuts of the up and down cut bits, you can see the top edge of the board where you used the upcut bit is a little rough. That same test on Spruce would leave one to two inch long fibers through the entire cut. So I have been thinking I could use a downcut end mill and set the toolpath to about 1/16" deep and go around the entire project at that depth, then change the bit to an upcut to accommodate the fact that the cut is going to 1/2 or more deep. That way I would have a clean crisp top cut, with no sanding, and a more even bottom cut. What do you think? Would like to hear your thoughts on this. Thanks again Garrett for all the videos. Jim Scott

[@IDCWoodcraft]

Hey Jim, great question! Your thought process is sound and I think this could work really well for you. I haven't done a lot of projects using spruce so I'm not super familiar wit the way it tends to cut. I'd say best method is trial and error on tis one. Worst case is you might need some sanding at the very end! Let me know how this turns out, I'd love to hear!

[@peterward8776]

Another thing i did not know "set last pass" thin for the clean finish far better than sanding thanks once again

[@IDCWoodcraft]

Peter, its the best time saving trick isn't it? I don't think i've ever met anyone that enjoys sanding!

[@jasonthevideogameguy3363]

Thank you for this! I've been racking my brain trying to figure out what causes these lines and how to fix them.

[@IDCWoodcraft]

Jason, no problem brother. I'm happy to help!

[@mikejones-km6fc]

Great information, can't wait until I get your bits and have a one-on one with you. I have all my questions ready--thanks

[@IDCWoodcraft]

Hi Mike. Your bits are on the way! I look forward to helping you.

[@marthacameron9459]

So two Aha! moments on this video....I've had my digital calipers for 5 years now. I mostly used them for pen turning. I ashamed to admit that I never knew you could use the calipers to measure the depth by using the other end. I was just compiling to my husband yesterday that I wish I had an accurate way of measuring the depth of something. Palm plant to my face... DUH. 2nd, while I understood the difference between the upcut and downcut bits...I didn't realize why the downcut bit leaves a burr mark. Now I know. Thanks Garrett.

[@IDCWoodcraft]

Martha. Never be embarassed. We only know what we know...until someone shows us!

[@lloydsnyder2738]

Well said. That last pass may take some time, but it is worth it.

[@IDCWoodcraft]

Hi Lloyd. Just turn up the feed rate for the last pass.

[@SnorriSigurdsson]

Good video, I'm taking my first steps in the world of CNC and this is grate information to me with almost no experience. THANKS

Hey Scott. I'm really glad to hear this. How did it help you?

[@jasonoliver2769]

Thank you for this advisory "trick". I think you're right as well. The people who find this out early on will have greater success on their projects, therefore, increasing their excitement and desire to create more. Well done Garrett!

[@IDCWoodcraft]

Hey Jason. Yes, I hope every single CNC'er gets to this video for that very reason. I think this is the most frustrating thing people come across when they start CNC'ing.

[@leonardsantiago7425]

Excellent you inspired me to go run a job right now to test this out. Love it thank you

[@IDCWoodcraft]

Hey Leonard. Let me know how it comes out

[@PeteHowlett]

I make two pocket passes. One rough cuts stepped down and undersize. Finish pass is full depth of cut rater - perfect sides and bottom.

[@IDCWoodcraft]

Hi Peter. You figured out the exact right way to do it!

[@yefrinabrego8360]

I’ve always been doing a .01 final pass and am still getting some of these steps. I appreciate the insight. I’ll try decreasing to .005 and raster thank you for the insight. Loving the hog bit! Keep up the great work!

[@IDCWoodcraft]

Michael, try it out and see how it goes brother! Glad to hear you are enjoying the HOG.

[@gregrodney5139]

When I first started down the dark road of CNC routers. I had the same problems, but what I DID observe was the lack of my machine's rigidity. Anything you can do to beef up your machine will minimize witness marks. You'd be surprised at what some light weight aluminum angle can do for a machine's rigidity. You won't eliminate the witness marks entirely , so Garrett's solution is the one to go with!

[@IDCWoodcraft]

Hi Greg. Thank you for contributing here. I always enjoy it when other CNC'ers add to things I miss.

[@nac4965]

this comment 100% i typically work with 2000 lb steel milling machines (bridgeport) that have zero rigidity issues- i was unpleasantly surprised while unpacking my next wave desktop cnc to find it was built with a plastic frame and aluminum top- the whole thing flexes under stress. I've already begun to contimplate rebuilding the entire cnc with aluminum!

[@dennisdoi8572]

I am a beginning woodworker and don’t own a CNC, but I do have a couple of routers. I had no idea how much difference the up & down cut bits cut the wood! I think you have shown me the reason for my messy cuts! Unfortunately I don’t have any down cut bits so I have to wait until tomorrow to use them!! Thanks so very much for your very excellent & detailed video!!

Hey Carlos. I'm glad. It will make your CNC life much easier, for sure.

[@katslod2]

Good stuff Garrett. I guess I did this with a second manual pass, but now I know what the finishing pass is for instead. This keeps me from having to create a second toolpath just slightly deeper. Much appreciated.

[@IDCWoodcraft]

Hi Kat. Yeah, it's one of those little features made specifically for second finishing passes so you don;t have to generate a second toolpath.

Great video, Garrett! While watching the video, I was thinking of making a final, thin pass with an upcut bit. Never thought of using vCarve to solve the problem with a final pass. That's the reason why I watch all of your videos. Thanks so much for your help. Stan

[@stewalameda6062]

Thanks for the info. I have seen this in my latest project and wondered if it was the setting of the bit in Z, clearance path for a down bit z setting and then resetting the Z again when the bit was changed to the 60 degree bit. I use at least 2 passes for clearance areas. I have also entertained the notion to add a 3rd pass but haven't gone that far yet. I just get the sandpaper out and sand the marks out. You have helped me get a much better understanding of CNC related stuff .

Thanks Joe. Yes, down bits do wonders!

[@kentturkow1572]

First time here. I enjoyed the explanation of up and down cutting bits. I think I found a channel I can learn something from. Thanks for sharing.

Hi Kent! So glad you're here. What kind of projects are you currently working on?

[@richardmcdonald9410]

Great video. After 40 years in machine work this wood stuff is a little different.

[@IDCWoodcraft]

Hi Richard. Yes, it definitely is. I had to relearn many things as well.

[@bigmac1598]

Hey Garret. For the downcut bit to pull down or the upcut bit to pull up or down by 0.040" as per your example surely there is either lots of play in the spindle bearings or backlash in the vertical (Z) drive or "give" in the construction of the machine

[@IDCWoodcraft]

Hey Mac. Yes, it was exagerated due to the machine. It is not super rigid. However I have seen many many posts in CNC facebook groups about this issue so i was prudent to share regardless.

[@jzclarke]

Came here to say this. I have run a few different CNC machines now and none of them exhibited this problem with pocketing, either with uncut or downshear tooling. There should not be that much slop in the spindle or that much backlash in the z axis. If someone experiences this, my advice would be to have their machine serviced and checked for excessive wear in these areas. Also, in the first comparison shot where the upcut and downcut grooves are side by side, the super ragged top edge and rough sidewalls usually are a sign of a worn out bit. I typically use up cutting bits for that type of signage and get clean top edges unless my tooling is worn.

[@IDCWoodcraft]

@@jzclarke Thanks for the input hHighlighted. Yes, rigidity is a factor as well as bit condition. However, I see this issue all the time in facebook groups. So there are a lot of fo machines out there with rigidity issues. Gotta come up with a solution for these folks.

[@patrickkemp8047]

Just finished a project and had to do a bunch of sanding. Now I know how to do it right. Sanding takes a lot longer than doing a final pass. Final pass looks better too! Thanks Garrett. BTW... the one on one sessions are extremely helpful!

[@IDCWoodcraft]

Hey Lenny. As long as the beginner sticks to this channel, they won't stay a beginner for very long!

[@BGraves]

If you software supports it, Inner corner feed rate reduction will do wonders as well. Use the stubbiest endmill possible. I plow everything away with a 90% step over with a stubby 3/8 or 1/2 with a light chip load to reduce large tearout. All the same concepts apply with metal as well except the metal doesn't rip out chunks from the tool pressure

[@IDCWoodcraft]

Brian, Great info, thanks for sharing brother.

[@anthonywindle7503]

Wow.... mind blown....I never thought about the pressure from the sides etc. I always thought it was the wood flexing.

[@IDCWoodcraft]

[@swampweb]

[@IDCWoodcraft]

Hi Dexter. It will definitely save you time. I'd rather my machine run longer than me have to sand. Don't you agree?

[@TorqueFork69]

This gave me a very clear example of taking every part of the project into consideration during job setup and design. Raster with the grain baby, yeah!

[@IDCWoodcraft]

Hey John. I'm definitely glad you got some takeaways. Yes, raster with the grain makes so much difference!

[@mikerussek4202]

Hi Garret, great video, love hearing the engineering explanation behind the reason. I happen to be using upcuts to pocket recycled hdpe plastic. Down bits melt it and cause a mess..the upcut pocket is super clean …but as you probably know I am experiencing the opposite whereas my line around the letters is deeper than the rest of the pocket.

[@IDCWoodcraft]

Mike, glad to hear that this video helped you! Try using a smaller stepover or stepdown and it might get rid of the line around the letter

The knowledge you have is tremendous. The time and effort you spend on other is teaching them is fantastic. What I have learned from your video I cannot express my gratitude adequately. Thank you so very much.

[@IDCWoodcraft]

Woodieaz, I am so happy to hear that my friend. Glad to hear that it helping you so much and that you enjoyed the video.

[@carlmainwaring4349]

This is a VERY useful video. I believe it actually saves me time because it omits having to sand all the little burs and ridges off. Thank you so much for the top tip!

[@IDCWoodcraft]

Hi Carl. You got it, brother! It's an obvious trade off. Let the router run a bit longer to avoid snading. I'm game!

[@scottvallie4495]

Thanks for the link this helped on some of the issues we discussed..

[@IDCWoodcraft]

Scott, glad to hear this one helped you brother!

[@thehamlinwoodshop]

Convinced me to start using the finish pass option. Thank you!

[@IDCWoodcraft]

Hey Hamlin. It'll save you a but load of time

[@randyhuffine8430]

Very good information. I am going to add this video to my go to tips. Ah Ha, the finished product.

[@IDCWoodcraft]

Hi Randy. A finished product with a good finish!

[@haroldlanfear3618]

I enjoyed the video and it had good information. A small negative was that I'd prefer less discussion. Some was repetition and I have to admit, I do have a short attention span. Overall, a good video and great explanation of the issue and how to fix it.

[@IDCWoodcraft]

Hi Harold. I do repeat myself. I'll work on it. Thanks for pointing that out, and for the compliment.

[@randito70030]

Great video and explanation. You my friend have helped me get a much better understanding of CNC related stuff. Your enthusiasm shows through in your videos and makes them a pleasure to watch.

[@IDCWoodcraft]

Hi Randito. Thank you so much for sharing that. Yes, definitely enthusiastic. Even more important...you have gotten much better at your designing and projects...the ultimate goal.

[@garyjadick1774]

Thanks Garrett was having this issue video just made me see what I am doing wrong.

[@IDCWoodcraft]

garyjadick, so glad to hear that brother! Happy CNCing.

[@JeffC-ct5jj]

I am new to cnc and really appreciate the info you provide. I don’t use Vectric software though, rather I use carbide create and carbide motion, but so far, things you have taught are easily transferrable. I am particularly interested in doing deep inlays, therefore, any direction you can point me in that will help with that would be fantastic. Thanks and keep on teaching!

[@IDCWoodcraft]

JeffC-ct5jj, I'm glad you find the information helpful! Deep inlays can create some stunning effects. A good place to start would be to experiment with different bit sizes and depths to achieve the desired effect. I have a video that is for Vectric users but it should be able to help you quite a lot in Carbide Create too brother! Here is a link: kzbin.info/www/bejne/hJLbomaJl7Z7a5Isi=0rClZxe2ZdMVGRPS

Garrett, you are the first person that I know of that has addressed this. I have cut a lot of projects where my CNC leaves multiple layers. And now I have the AHA moment. I spend a lot of time with sandpaper to remove the "steps." I understand that putting in a finishing path will increase the time of the project, but I am loosing the same amount of time in hand sanding in large and narrow areas. I think this may be a wash for me. And less tedious. Thank you.

[@IDCWoodcraft]

Hey Reg. Honestly, I think I'm the only person who has covered this. And so necessary. I saw so many people having this problem that I had to get this out there. This will save you a ton of time now that you get it.

[@larsplovmann4280]

Hey Garrett . im a totaly newbe in to CNC, and have to tell you something :) you have a very good channel and you are great to explain, besides you are a pleasant person :) I enjoy watching your videos, and have learned quite a lot from you. Thank you

[@IDCWoodcraft]

Hello Iars. Thank you! Do you have your CNC machine yet?

[@larsplovmann4280]

@@IDCWoodcraft HI Garett. Yes i have a small Dremel CNC with 500w. spindel / motor. I know this a small and cheap CNC, but to learn and se if its me, its ok. Im a 3d printer man, but woow this is hard to learn :) But I like it so much, and use much time with Vectric Aspire, and UGS :) I begin to get it under my skin :) I only have ( for now :) ) some 3 mm down endmill, and a very small 0.8 mm ballnoise. And offcause I have to get others. //Lars ( and hope you understand :) Im from denmark :)

[@IDCWoodcraft]

@@larsplovmann4280 I understand. So... Do you feel like this cnc router stuff is a go for you?

[@larsplovmann4280]

@@IDCWoodcraft absolutly 😊 its simular to my 3d printer and laser Bobbys, so i think i her ind more hobbyes 😉 So now i just have to se more videos from you to be a champ 😁

[@Grumpyoldtwit]

@4:15 That's weird. I had the opposite problem today. I'm making some stacked text signs, pocketting with a 1/4" upcut bit and finishing with a 1/8" downcut. The 1/8" bit seems to cut a tiny bit deeper, leaving ugly marks on the bottom. I'm using a probe plate. I figure I need to adjust my Z zero on the 1/8" bits up by about 0.2mm

[@IDCWoodcraft]

Muz, it may have something to do with machine rigidity my friend!

[@chavezm1954]

Wow! Thanks so much! This also explains why there is such a big difference when using a 1/4 down roughing but followed by a 1/8 uncut bit inside a 3D sign. It’s been driving me crazy!

[@IDCWoodcraft]

Hi Mike. Exactly! This will definitely change the game for you.

[@billteague8709]

Agree

[@Harmonie-jg5jh]

Hi Garrett - appreciate the great content. You’ve been a big help getting me started with my CNC journey. I was curious if you have revisited this issue now that you have the Phantom? I have a Shop Sabre 23 which is built like a tank and I don’t see the same deflection that you show here . Of course any time you examine a milled pocket you can see visible lines from the step over but for me very minute. Showing the differences from machine to machine based on rigidity and build quality would be good informative content. Thanks for all your help!

[@IDCWoodcraft]

Harmonie1814, I'm glad the videos have been helping brother. The Shopsaber is an awesome machine, definitely built like a tank! You bring up a great suggestion showing the differences from machine to machine. I'll add it to my video to do list brother. I appreciate the insight!
