CrossFire XR Modifications - Making Langmuir Systems newest table fit in my shop.

[@PaulThomas-qo9vy]

Sharpening drill bits hints & tipss: Buy the largest Drill Doctor (XL 750 or 750XL which has 3/4" dia. max capacity. I used to work in an auto research machine/metal fab shop & became the "guru" & trainer for sharpening on the Lisle 9100 drill grinder & sharpened drill bits a few thousand times. Snugly adjusted, & stone wheel diamond trued, it sharpened well, but was Slow on larger bits (1" to 1 1/4" max.) I developed a post-sharpening technique (Pro Tip) with 150 to 180 grit sandpaper. I tear a full sheet into quarters, then fold or roll the quarter-sheet so it fits the groove in the bit (grit facing out). Next, I fit it into the groove, maintaining the Angle of the groove & slide the grit across the groove side of the cutting tip, removing the dwarf that rolled over the edge during the grinding procedure. I may gently stroke both sides of the cutting edge (stroking AWAY from the tip, Not into the edge, which dulls it & tears the sandpaper. Drill Doctor tip:Learning to Index the bit is the first thing to learn, watch their video instructions several times! 2nd get 3/8" to 3/4" dull bits initially. They are easier to see what's happening, if things go wrong. Most people blame the Drill Dr. for goofed up bits, when it's them that lack understanding! I get Great performance from them Every time, because of prior understanding of drill bit geometry & lots of experience with other sharpeners. The big Drill Dr. has a bonus feature to make regular bits into Split-Point bits, adding secondary cutting edges to the center (web), like having a built-in pilot bit for faster drilling! I hope this helps! Practice & practice! Sharpens cobalt bits & carbide masonry bits easily too!

Thanks Dave. Another great video.

[@David-ir9dx]

Thanks for more great information and cool ideas!!

[@bumpstart21]

Thanks for detail videos on the XR. For the folks like myself considering a plasma water table can you comment on the ventilation requirements. In colder climates that water table will turn into an ice rink with the shop door open.

[@Elevator74]

That was one of the best Fusion Tutorials I've seen and it was probably unintentional on your part.

[@mikematthews2479]

Awesome!

[@bear4380]

Great video! Again

[@dirtdyscrasia2190]

Great creative problem solving.

[@ntdracing]

on a budget.

[@78heloman]

I just drained my table for the first time, and now I’m here getting your list so I can modify the drain too. Thank you, saved me some time!

[@ntdracing]

Cool…I just watched you CJ LS swap video. Really cool. I have an LM7 in my shop wired and waiting for the right CJ. Maybe after the next race truck.

[@78heloman]

@@ntdracing i know the feeling, I have another CJ project too; but it’s at least 3 or 4 projects away…and, now that I got this table, I want to redo everything on the current project.

[@mikedawley1461]

Great mod for the table . I am awaiting my Crossfire XR to arrive soon in transit . Thanks for the great videos, I have a lot to learn as this will be my first plasma table….

[@GeneralChangFromDanang]

I'm definitely going to move the screen and pc. Too much water splashing in that area. Also going to 3d print some collars for the cords going to the control box so water can't run into the enclosure.

[@bens3641]

Great ideas and nice explanations as usual. Thanks for taking your time to make and post....hope they are making it worth your while.

[@ChrisS-oo6fl]

Lol the wireless key board included by Langmuir is just a BLE keyboard. The exact same model is available on AliExpress right now for $2.99 normally $8.99 free shipping. “flying G mouse mini keyboard”

[@matthewgorman1088]

Very nice, clean setup, makes me want to upgrade.

[@FatGuySAWZ]

Dull drill bit+ lite hand+ belt sander+ practice =sharp drill bit. I usually put a little more angle on them and they seem to cut better.

[@ntdracing]

Thanks. Will try that.

[@nicholashabersetzer3574]

Just technique for sharpening on a bench grinder. Otherwise I found that a sharpener called the drill doctor works pretty good

[@ntdracing]

Thanks

[@seabreezecoffeeroasters7994]

Enjoying the Plasma journey, shame they don't allow freight to Oz at this stage. With Fusion look around for a little help on either the pattern and or the mirror command will save you some time and effort for regular multi hole layouts :) I have a love hate relationship with the sheetmetal environment but when you get it dialed in having it calculate material bend allowances is a great thing to add to your toolbox.

[@charlesruth8630]

Excellent video!!

[@Duck4Evers]

Great videos thank you so much for uploading!!! Beside the obvious that once its done you cannot take it apart, why wouldn't you weld the four water bays together? it seems that most of the complaints about the water reservoir is that they leak. I really don't know enough about the product but it seems like a reasonable fix. TYIA!

[@johnvansloun7443]

Can you do a shop tour video? Honcho looks great! I’ve got the smaller Langmuir table and just added the larger table and cut controller and THC.

[@ntdracing]

Planning on a shop tour right before we leave for Baja. Thanks for watching

[@bogdankril]

Tank you for another awesome video. I do like how you are including Fusion 360 video at the end👍 Looking forward to the big project you have coming up. (You always mention HOT KEY, what is the hot key on the keyboard?)

[@ntdracing]

Hot key is like the letter l always brings up line and c brings up circle without having to click on the top bar.

[@CraigHollabaugh]

No drain in all the chambers, LS fail. Hope someone over there watches your videos for design mods. Thanks for video.

[@ntdracing]

Does seem like it would be a really easy mod for them...maybe they will use my idea. Thanks for watching

[@CraigHollabaugh]

@@ntdracing Crossfire, Pro and now XR, drainage seems like an afterthought for Langmuir. You, I and others have solutions, mine's a hack, around their poor design choice that actually work. Please post an update video after you've used your 1/2" tube solution for a while. I'm interested to hear if 1/2" diameter was sufficient or had clogs due to debris. Thanks for fast reply this morning.

[@ntdracing]

I think it will be ok. Will let you know.

[@mrsawbladehead]

Are the motors hot to the touch even before running the machine? Mine are and I haven't even ran the break in mode. You seemed to have no issues with yours but my experience has not been good and I haven't even made a cut.

[@brownspmw1521]

Did you have to get a longer torch cable to relocate your cutter? I can only seem to find 20’ torch cables for my plasma and i’m worried about it being to short on the XR.

[@roberth1858]

Have you tried to add closed loop servo motors ?

[@ntdracing]

@@roberth1858 no…I like the way the machines work right off the shelf. They just work well.

[@scottyp.644]

How is the dimensional accuracy?

[@theleaderthelegend1313]

I’m doing this exact thing. Just wondering if you couldn’t keep it hooked up to your water hose spout would you put a shutoff ball valve on that far end to keep it from draining when unplugging it from your water spout?

[@ntdracing]

Sometimes I leave it connected. Other time I just make sure the end of the hose is higher than the level of the water in the table. A valve would be handy.

[@theleaderthelegend1313]

@@ntdracing mine will be on the opposite end of the shop so I can’t leave it connected once I fill it I need to be able to seal it off and roll it up. Would you still recommend this method?

[@theleaderthelegend1313]

@@ntdracing I think I just figured it out. On that last t bar put a ball valve in between that and the hose so that way you can disconnect and roll it up

[@truethinker68]

Work bench size?

About to buy click your link not see $100 discount asking for a discount code do you have one.

[@roberth1858]

So you’ve never had an issue with the machine missing a step and messing up a whole sheet of steel?

[@ntdracing]

@@roberth1858 Never. Works great. Never had a problem with the RW45 either.

[@78heloman]

No issue with the Amazon basics usb cable, they’re clearly very concerned with shielding?

[@ntdracing]

No issues yet

[@wiggymccrackin8418]

Does it come in a dry table option?

[@ntdracing]

Good question. You could make it that way if you wanted, but the water table is really a part of the structure that keeps the table square.

[@wiggymccrackin8418]

@@ntdracing first, I appreciate your prompt responses. Would it be possible to attach some kind of downdraft system to avoid the smoke?

[@ntdracing]

First I would say that the water table does an ok job keeping the smoke down. If I was going to make some kind of a downdraft system, I would attach it to the bottom of the water table then drill a bazillion holes in the water table. The slats that hold the material you are cutting sit in the water table. The bazillion hole plan might let you suck smoke through the Swiss cheese water table and retain the slats without having to engineer something new.
