My Rigid table saw was looking over my shoulder and was ecstatic to see yours, said it was the first time he didn't feel like a red headed step child in years.
like the idea of using a silicone membrane as even when the termoplastic tears inside its frame it will still form over the mould giving a larger chance of success have to see how far a membrane can be stretched though as the parts im planning to make are kindof tall you ca allso use sheet sizes that are smaller than the workframe of the former the membrane is the size of the machine , the frame holding the plastic can be simple just a basic mdf frame with sunken in screws , it just needs to be smooth not to cut intoo the membrane , can even pressurize the top of the membrane to apply a little extra force on the part
Speaking from experience, MDF is not a great material for vacuum tables. I used it on my first table and never got great "pull". I found out from others that MDF by its nature is porous, causing the vacuum loss. I bought a piece of scrap Corian countertop material (almost as cheap as mdf). It cuts and drills very easily and holds up to vacuum and high temps.
Also, instead of the silicone membrane, try 1/8" neoprene foam. It holds heat better (and can be preheated) thus giving better definition, especially when using a lower flow vac pump like the HF pumps.
Why don't you just mount your kydex in a frame, heat the framed kydex, place the framed kydex on vacuum form and vacuum. Now you are actually thermoforming. you will have minimal heat loss and better definition in your parts. ABS is also a good TF plastic. It is economical and has a low memory set temp.
ABS tends to deform easier which is not good when working on the retention of a sheath. As for the framed Kydex there are a lot of people who slap down a big piece of Kydex and then press down the edges with a metal frame. It gives better definition and is easier to cool faster. The downside is you use a lot more Kydex since it has to have enough overlap around the edges of the mold.
Get behind that table saw. The you are using that saw is very dangerous. you are risking kickbacks so much more than you realize. Also when you cut that narrow piece of MDF you really should use the table square. Just a few friendly tips from a guy that has been using table saws for 25+ years.

Thank you sir ❤ this video very help full for my new business I started kydex holster making business
That’s a cool idea!
Anyone else getting the willies when Walter was using the table saw? 🙂
Walter, like a wolverine, isn't afraid of much. Unorthodox method with ample care and concern applied I'd suggest. ✌ 😃
Atrocious technique
Yeah man. Fingers are too important to risk with unorthodox table saw techniques
I’d like to know how many people this man has taught how to make knives.
@@ShawnCantwellKnives me too
Great job!
That is sweet ,first I've seen .
Great video awesome tool
It makes great gun holsters too.
Thanks for sharing 👍

I got a message from you that asked me to contact you re: the basic measurements on this project. I can not find that meassage.
Cheap harbor freight on / off pedal for the vacuum helps a ton
I have a 2.5 CFM vacuum pump, will it work for kydex?
What are your overall dimensions? Thanks for all the information you have provided over the years.
Thanks again for sharing your time and talent! KANSAS
Where did you get the membrane?
What kind of silicone are you using? For the suction
Where can i find the blue prints to make this press?
I joined your patreon and cannot find these plans.

I'm about a minute in and I'm wondering if a homie has perhaps been watching T-Rex arms?
Not familiar ?? Take a look at my channel .. hundreds of videos there.
Think its time to send that torch to retirement, lol
No heat

If you dont have a cnc, mayby you can 3D-print it

Agreed, I was cringing just watching how he was using the table saw
MDF is one of the worst things to use as a subfloor in a house.
That is some scary table saw work there. Step One, learn to safely operate your shop tools.
Please, please, watch some tablesaw safety videos. I work in healthcare. I’ve seen finger amputations.
