Hey guys, I'm currently using double sided tape on MDF to hold down my aluminum sheets (0.040-0.050). I run a coolant mist as well to prevent my bits from gumming. While it works great, after a few cuts the MDF begins to soak up the coolant. Also taping the parts down and removing them after parts are cut is getting very tedious. I'd like to switch over to custom vacuum fixtures for each part I cut.

I'm thinking some sort of plastic spoiler board would be the cheapest solution without deteriorating from the coolant. I will need 4-5 sheets of 2'x4' for the various parts I make so I'm looking for the best bang for my buck. Does anyone have some recommendations on what material to use? I also had a link to a company that made the rubber seals for custom fixtures but cant seem to find it. Any references would be great.

Also if any one has pictures of custom vacuum fixtures for job specific parts I'd love to see them!
Thanks in advance

Hi,

If you look at my video and go to 23.36 on the timeline it talks about my fixturing process.

Keep in mind the particular fixture I made had no internal holes and the gasket held the piece of plastic while I engraved it. Alstar Adhesives has a good technical support person that can help you with your particular project. Give them a call.

Hi Zorbit,

Thanks for the favorable comment. I made the video to help me remember what I did and how it all works. I am glad it also has helped other people who might be doing one or more of the items I have already done. The router has worked really great with no problems. I can thank my friend Don for helping me will all the electronics. Did exactly what he said to do and it works as advertised. Ha Ha
