- In this video I will make Vacuum Pods as way to hold material down for cutting on your CNC.

Great project!!
Vwey useful clamp system.
Thanks for sharing
Thanks for sharing, worked great.
Your awesome!
Thank you for your videos they are very informative keep them coming.
I have the rockler ones and they're great!
I just added the Thingiverse file location enjoy!
Hi, the link doesnt exist
@@Hughzywok1 Try the link now, it should be working. You can also try searching "vacuum clamping pods". Enjoy!!
Hi I just found this video. Is it at all possible to post the file for the pods that you ended up using in the video instead of the blank block? I am horrible at freecad. Much appreciated.
@@noelflores8989 What file format are you needing?
Honestly mate, well done what an awesome and useful project. you can tell youre proud of yourself after you were finished with the mods and so you should be! ive been thinking of buying the festool vacuum clamps and theyre $1000 each! i dare say ill be making my own after watching this video! awesome stuff.
Thanks, It was a fun project and I was excited when it worked. I also looked at different alternatives before making my own. I did learn a couple of things, first I need a more powerful vacuum pump and second I think the tube size needs to be a little larger. Good luck on making your own, let me know how it turns out.
I'd like to share a tip about vacuum pods; try using high pressure laminate (HPL) for the pods. It is a material similar to Formica, only thicker. I have bought scrap pieces from a furniture factory, where they use it for table tops. The pieces I've got is app. 1/2" in thickness. Although it is a very hard material, it machines beautifully with tungsten carbide bits. I find it to be less slippery than HDPE, which is desirable in this application...
Thanks for the tip, I have worked with HPL before and will have to give it a try for the vacuum pods.
The only concern is this: you need to surface the pods because no 3D printer can print perfectly squared surfaces. You need to surface them on your CNC after you printed them if you want accuracy.
Thanks for this. I bookmarked this video a few months ago and finally getting around to making these. I am using my resin printer for the pods, we will see how they go but should be fairly accurate and smooth.
I do a lot of signs using PVC and because it's more flexable than wood it tends to bounce a lot giving poor finish unless you use double sided tape to hold it down. The issue is tape isn't reusable and can start adding up with enough signs.
I hope these vacuum pod work for you, maybe a vacuum table would be a good solution?
@@smedleywooddesign2219 I ended up designing a 11inX11in pod that I made with the CNC out of a 1in thick cutting board since the bulk of my work is 12inX12in signs.
Still waiting on the rubber seal to get here to try it out.
If I would have looked at your links before I went to Lowes I would have saved over 50 bucks on these fittings and hose.
Sorry to hear that. My go to for parts like this is has been Amazon lately, they seem to be the cheapest, that I could find. Thanks for watching.
@@smedleywooddesign2219 I got the rubber round cord in today and it fits and seals even better than the lowes stuff I had in there. Thanks once again for sharing your resources with us. On my Harbor Freight pump I 3d printed a fitting to go from the fine threads of the pump exhaust to accept a 3/4" piece of pipe so that seals up nice for those of us that started with the less expensive oil vacuum pumps. It's all working very good. Your pod design now has me with 6 printed pods. 2 of them will go for a sanding jig that I can clamp on my work table. The other 4 will be used with jigs that I make for some of my Royal Ranger awards and gifts. Canteens, Lanterns, Cups and plaques and signs of all kinds.
Now that it's all working it's time to organize it so it functions well with my setups.
You might consider getting a 5-10 gallon air tank to just as a reservoir for the vacuum pump. Gives you a little safety factor :)
I have seen that done before, I’ll have to give it a try thanks
I was about to draw these up for myself in Fusion 360 when I found your video, so thanks for sharing! Can you share your printer settings for these...and how well they've held up?
I am printing everything on a Ender 3pro using Cura for the slicing software. The settings I am using are from the CHEP TH-cam channel, here is the link to those profile setting, www.chepclub.com/cura-profiles.html I think there are 4 different profiles to choose from, for the pods I used the "Good" profile. So far I have cut out 6 parts with pods and they worked great for holding down melamine sheet, I could not get them to hold MDF or any types of hardwood. I need to play with it more to see how I can get it to work for those material. I hope this help, Enjoy!
@@smedleywooddesign2219 Hi thanks for the nice video. Are you already able to hold down MDF on the pads. I use a lot of MDF so that would't be nice.
Thanks for posting a great design with links that works great. Printed one to try it out and it works great. Printing 3 more. Thanks for the links and the tip on the die at Harbor freight. I do have a question. My Harbor freight vacuum pump is doing a lot of misting when it is really holding down the parts. Is this normal?
I'm happy to hear that these are working great for you. For the misting, I'm not sure why your pump would be doing that, I did not see anything like that coming out of mine.
@@smedleywooddesign2219 The vacuum pump you have is the more expensive type that is oil less. If I get to doing alot of vacuum clamping I would upgrade to the oil less pump or vent the oil ehaust outside after it passes through my filter.
Hey thanks for the files. I'm going to print and cut these when I get home. Did you find the HDPE or 3d print held better? What infill did you use, did you seal the 3d print at all, similar to how you would with mdf?
I appreciate the help and thanks again for the video and file
HDPE and 3D print both worked about the same. I did not seal the 3D prints they worked great. For the infill I used 25%. Sorry I did not get back to you sooner. I hope these workout for you.
@@smedleywooddesign2219 no problem at all! I appreciate the follow up
How did you attach the pods to the spoilboard? Do you have a vacuum table? or did you use some double-sided tape?
I have some threaded inserts in the spoil board, I secured the pods down using those.
Let me understand correctly... You buy plastic corners and use them to mill out plastic.. Why did you buy??
Would you have a cnc file version if someone doesn’t have a 3D printer?
I can provide you with the DXF I used to create the cnc file. The layers of the dxf are named the depth of each tool path or pocket. It's probable best that you create your own tool paths from the software you use to make cnc files. I added the dxf files to Thingiverse.
have you thought about resin casting the pods?
I have not, I am not sure how to do it.
What 3D print settings did you use to print Pods?
I am printing everything on a Ender 3pro using Cura for the slicing software. The settings I am using are from the CHEP TH-cam channel, here is the link to those profile setting, www.chepclub.com/cura-profiles.html I used the "Good" profile. If you do not use Cura the setting I used are, Layer height 0.2 mm, wall thickness 1.2mm wall line count 3, top\bottom thickness 1.0mm, infill density 25%, infill pattern grid, print speed 50 mm\s . I hope this helps. let me know how they turn out. Enjoy!!
What's the power rating of your vacuum pump?.
Here is what is on the label 115v 3.1amps 1/4HP 1625-1375 RPM
It’s “these” period. Not “these ones”
You might try using cotton swabs and CA glue to patch those holes instead of Bondo. Ready to re-drill in 5 minutes.
Thanks for the tip, I will have to try that.
