I Just Had To Share The Excitement!

I was getting ready to pull a project out of the vacuum press and I decided this would be the perfect time to shoot a test video for my new audio equipment. Besides that, popping the vacuum press open is one of my favorite moments in the shop – and now you get to share in it!

In this video, I do not get specifically into the step-by-step of bent lamination and using the vacuum press, but it is highly informative. You will get to see the actual moment a project is pulled out of the vacuum press and the information I share is good context based, working knowledge for bent lamination procedure and product.

This video shows a good example of how a vacuum press might be used. The vacuum press is a great tool to have in the shop. It has opened many doors for me since it allows for easy clamping of projects in a way that standard clamps cannot. The vacuum press really made veneer work a much more simple and lower risk procedure in my shop.

Nick Brygidyr recommended another bending plywood as I was creating this post: Italian Bending Poplar

Hope you enjoy! Your friend in the shop-

Hi Todd, Nice video. Thanks for making and posting it.

I usually cut some kerfs on the bottom of the forms for the pressure to equalize. A couple of quick passes on the table saw does it. That way the pressure relief holes are right at the bottom of the form and closest to the platen grooves.

Have fun with the project and please post it during or at least when it is finished.

John – Yep, it doesn’t take much really. The bag evacuates at a fairly slow speed so the form does not really need anything more than a couple kerfs to allow the air to continually flow out fully.

Todd great. I also love to open the bag and see the output of the work.

I’ve only pressed flat panels as of yet. I need to try some form veneering. I also want to make a 2 part vacuum table where the top is seperate so that it’s easier to get the item in the bag. You set it on the table and then drop the upper frame on top.

Karson – a system like that would be nice. Using the platen definitely makes it easier to slide work in just as you saw me pull it out.

Grizz you will have to get into vacuum pressing. It is awesome!

Todd: I’ve been using a solid platen on the bottom for a long time. I got tired of having to cut an just a little oversize platen to put on top of my panel. So I veneer upside down with the platen on the bottom then the veneer and then the panel itself as the top platen. I need to do 2 veneering’s to get both sides covered but that’s not a problem for me.

I’ve been using butchers paper as my covering. It’s paper with a plastic coat that peels off of glued items. It’s cheap to buy a roll and is use it over and over if I need to.

Karson – basically you are using the platen as a caul in that situation.

I have no doubt the butcher paper would work as well. As a contractor visqueen is just something that I buy anyway but it is probably more expensive on the front end of the purchase than butcher paper.

Of all the things to learn from this video, what I took away was this:

Unibond 800 + peanuts + 3 weeks to April 1st = great office prank

Thank you so much Todd !
I just bought a sheet of 3/8” wiggle wood and sheet of bending poplar.
I’m slowly setting up to do vacuum forming and veneering. Have the bag and vacuum pump.
This video was very exciting to watch, I can’t wait to start.
Good to know about the holes in the form, I was wondering about the space void and how that effects the vacuum.
Looking forward to a video on veneering process : )

Thanks Bluepine.

Dustbunny – the worst thing the space void might do is just hold air in reserve after the bag is drawn down, then releasing it slowly causing the pump to short cycle until all the air is out. This is just not good for the pump.
