Hold Down Blocks - CNCnutz Episode 90

[@benvandermerwe2359]

Thank You Peter. Just what I needed to see. Thank you for truly sharing the files.

[@Phil-os3hu]

Thanks for the file. Enjoyed watching you in action. From New Zealand

[@hudsonriverlee]

Love the simplicity. I have some odd pvc panels thick enough to make hold down clamps with. This allows me the maximum use of this material.

[@cncnutz]

They are great clamps for sure. Cheers Peter

[@Barrysworkshop]

I appreciate you making this video. This was the first project that I made with my recently created MPCNC. I now have a good supply of holddowns available, and a bit fewer pieces of scraps cluttering the shop. Also, since these are so easy to make, I don't worry about letting them be "sacrificial" when the need arises. Win-win-win! FWIW, I did make some from MDF and used some thin CA to support the underside (to avoid splitting).

[@cncnutz]

Thanks Barry. You can never have too many holddowns. I found that MDF would delaminate when you tightened it down. Is that CA glue you used? Cheers Peter

[@loubarchey2823]

I am collecting parts to build a gatton cnc, I have watched through my roku lots of your Episodes and give them all thumbs up. I find them informational and educational as after watching them I have to go educate myself on all the information ! Great Job !!

[@cncnutz]

+Lou Barchey Thanks Lou. Glad they help and all the best with your build. Cheers Peter

[@keithstanley2007]

Many thanks for the EXCELLENT videos and the files you shared!!!

[@markkottwitz6176]

Great idea. Great way to use up some offcut material, that would line the dumpster, otherwise. I looked up the material, and it appears to be a material similar to Komacel, and I have a few off cut pieces laying around the shop.

[@cncnutz]

Thanks Mark

[@michaelhenderson5098]

Just found your video a few days ago. I made several of the hold downs today. I think they will work just fine. Thanks.

[@cncnutz]

+Michael Henderson Thanks Michael. I find they work really well. Cheers Peter

[@MACKdaddy1220]

Thanks again, for taking the time to make and share your videos. Always first rate projects and technique.

[@cncnutz]

Thanks Bruce. Glad you enjoyed it. Cheers Peter

[@shaunwhiteley3544]

Thank you for the files, your CNC videos have been very helpful to me, a newbie with my first 3020 CNC machine. Hope you're ok and come back and make some more videos someday. Take care :-)

[@davesmith856]

Very Sweet! You make great videos! Thanks for taking the time.

[@MentallFloss]

Thank you very much for these videos Peter, they really help a lot.

[@cncnutz]

Thanks for watching, I'm glad they help. Cheers Peter

[@abouttheravadabuddhism]

Thank You! Just the sort of thing I was looking for.. Much Appreciated.

[@cncnutz]

Thanks. They really are great little clamps. Cheers Peter

[@AlwaysCensored-xp1be]

You could make some staircase blocks as well, it is thick enough for four or five steps.

[@MarkLindsayCNC]

Nice, Peter! Do you think HDPE would be a good material for this project, or do you think it's too "slippery" to effectively clamp a part down when in use? I love the idea of using the template to position the cutter immediately after running the primary job, then loading one file or the other, then machining the clamp. I have enough scrap floating around here as it is - waiting to cut a bunch of clamps would just add to the clutter.

[@danielkitson6878]

hi peter, great video and thank you for sharing your files i am sure they will come in handy. Daniel

[@HermannPlatschka]

Nice video! ... and your clever Jig for positioning the x/y axis is great. :-)

[@cncnutz]

Thanks Hermann. The little jig really makes life easy. I used to guess and got it wrong more often than I care to think about. Cheers Peter

[@bradselph6463]

Great video bud keep up the good work.

[@davecox900]

Peter what material are you using there ?

[@malcolmtemporal6571]

this a nice video very good but were can I get some plastic

[@cncnutz]

HDPE plastic should be availabe at many locations around the world. If you live in New Zealand you will find Signex offcuts at Sign makers. I don't know where you get it elsewhere in the world. Try Amazon or Ebay or Use hardwood if you have some about as it will work just as well. Just make sure you align the grain the right way and it should be just as good as plastic. Here is an affiliate link to some HDPE I found on Ebay. ebay.to/2VyF0lR cheers Peter

[@jobyonespellman1534]

Hi Peter. I live in Christchurch and have a Ox cnc machine. Interested in the signex sheet. From the comments you buy it from Mulford plastics in Chch...guess that would be cheapest? Would like to get some to play with. Thanks for the videos.

[@cncnutz]

Hi Jody, I actually get off cuts from a sign maker as it is used to make signs. Check around the CHCH area and you should be able to find offcuts tht are no good to the sign maker but ideal for you, depending on what you want it for. Might be worth a look for you. Cheers Peter

[@friedchicken1]

2:48 you're lucky your machine produces music while cutting. Mine produces only noise :(

[@cncnutz]

+friedchicken1981 You need to get the next model up, it talks. 😉

[@friedchicken1]

xD thanks :) ;)

[@mannyyabar7659]

Hello Peter, is that PVC material? And what type of cutter ( bit) is the one you use? thanks

[@cncnutz]

+Manny Yabar The cutter is a 6mm straight flute cutter. I find that seems to cut best for me though and upcut would do just as well. The material I believe is an expanded PVC of sots. Cheers Peter

[@mannyyabar7659]

Is it one flute?

[@cncnutz]

+Manny Yabar 2 flute

[@andypowlesland1]

Great Video, where can i source this plastic in the uk? looks good for prototyping!!

[@cncnutz]

Sorry but your guess is as good as mine. Try a local sign writer. That is where I got mine from. and you're right it is great for prototyping. Cheers Peter

[@andypowlesland1]

Thank you peter, great idea!!

[@DickTulane]

I found PVC boards at Lowes that work very well

[@denouch358]

Great video Peter. I am not familiar with this type of material. Do you know if it goes by a different name in the USA and where to buy it? Thanks.

[@cncnutz]

+Denis Renaud No I don't sorry Dennis but I think there are discussions about it in the comments of this video or it might be one of the other holding clamp videos I did. Cheers Peter

[@mtabernig]

C'mon, Man, it is easier to cut them in the table saw. By the way what the buttons in the main mach3 screen 2go and offline do? I never try to use them.

[@cncnutz]

Good question. I'm like you and have never used them.

[@mtabernig]

sorry, i did not mean to sound like an ASS, however i am curious about them. i check the manual and found no mention of them.

[@cncnutz]

You didn't. I had to have a look quite hard to find them. And you are right. A table saw is much quicker but not as much fun. Keep making those chips. Cheers Peter

[@mak4142]

HI there what machine do you have? as im new to cnc

[@cncnutz]

+Michael Kemen It is a Joes Hybrid. A homemade machine. www.joescnc.com Cheers Peter

[@jimanderson8173]

Where do you get the sheet stock?

[@cncnutz]

I get mine from a local sign maker. The material is called Signex and is made by Mulford Cheers Peter www.mulfordplastics.com/products/signex Signex® is similar to a PVC Foam product but with far superior quality for more demanding applications. The manufacturing process results in a "skinning" or outer layer of the foam board creating a harder, smoother and more scratch resistant surface along with increased mechanical performance. Signex® is a very strong, durable and light weight product that will not rot or delaminate like other products making it perfect for the signage and building industries. Signex® is very chemical resistance and can be handled and worked with like many other building products such as timber. It can be routered, glued, filled, sanded and painted with standard woodworking tools whilst providing an improved surface finish. - See more at: www.mulfordplastics.com/products/signex#sthash.p3NFvtxv.dpuf

[@LexMexNow]

Please. More info on the material used. Spell the name. Maybe a link. Thanks.

[@cncnutz]

Thank you for sharing

[@cncnutz]

Hope you find them useful. Cheers Peter

[@willford8475]

Excellent, if you get short of a few bob you could sell these for USD 10 + p&p a pair easy!

[@cncnutz]

Sold! How many would you like sir. Cheers Peter

[@willford8475]
