Jimbo - thanks for making this magnificent site available. I've just downloaded these templates and am thrilled - measurements at last! Very Happy I've got no access to a 'real' suit, so these plans are like gold! Thanks again. Phil

Hello Phil!

Glad to see you over on this board. Your prop making and vac-mold making experience will be a valueable contribution to this new board. For those that might not know, Phil, aka Blaxmyth is the inspiration and motivator, my mentor when it comes to MDF mold making and vac-forming. Without his encouragement and tutoring, the trooper project would never gotten off the ground.

I'm glad you found Israel Franco's templates helpful. He gave them to me to post and share. They seem pretty good. Let me know how they work out.

Jim

Hello! Good to hear from you!

The molds will hold deep detail up to about 1 inch deep.

The wrinkles in the plastic might be too hot or too cold plastic. Can you post some pictures? I might be able to tell you what the problem is if I could see what the wrinkles looks like.

The wrinkles as I understand it my be caused by one mold being too close to another mold. This is called 'webbing' and happens when 2 or more molds are close to one another. As the plastic is drawn down to the forming platen, the plasti stretches too far and it fall onto itself.

I have not seen any other wrinkles with HIPS material. I did try some ABS, but it had a textured side that caused all sorts of problems.

If the wrinkles are in the mold, sand your mold using 200 grit sandpaper.

I have good success with a 3hp shop vac. I have used a 6.5hp shop vac and the additional horse power was not that much better than the 3hp.

Great job on those templates Israel,they're very professional!

Looking at the plastic formings,it looks like the problem is your moulds are not so smooth.Vacuum forming is not forgiving and shows up every little imperfection in the moulds.At least that's what I think,I've never had my plastic go like that.Even when overheating it just goes like 'orange peel'.

Hey jim,so the multi-vac is no good eh?

I do have two vacs now as I recently bought a triple motor vac,which is a bit more powerful than my twin motor.I am going to try linking them up and see what,if any difference there is.I plan on doing the water test thing,where you measure how far the water gets sucked up a clear tube/pipe.

How is your trooper helmet mould coming on?

-Paul.

Hi Paul!

Good to hear from you. I agree, the molds might not be smooth enough. I have never had any issues with the plastic either. ABS yes, but not with HIPS.

As for the multi-shop vac setup, I can't tell much difference if any. IMHO. I have a 3 and a 6.5 hp shop vac, and to be honest, the 3hp pulls as well as the 6.5. The hose diameter might be an issue, as the 6.5 has a larger hose.

I have since traded for a nice Robinsair hi-vac pump, 6 CFM, and will start replumbing my table in November.

I have not tried the water in a hose tip, I need to do that!

Jim,

I will eventually upgrade to a high vac set-up,but for now the industrial vacs will do.Once I finish these new moulds I'll consentrate on the vac system.Of course,I'll see how yours goes first Laughing

I got the water test from the DIY vacuum forming book.It's a great little book which I think you already own.I have two which I highly recommend for anyone reading.They are:-

'Do it yourself vacuum forming' by Douglas E.Walsh

'Secret's of building a plastic vacuum forming machine' by Vincent Gingery

Both very informative with great tips on all aspects of the process.I'll let you know how I get on with the test,though I'm not hoping for much Sad

-Paul.

I'd be interested in learning about the water and hose method of measuring vacuum. Sounds intriguing.

I used a rough and ready method - got a vacuum guage (car dashboard type), pushed the tube through some plastic card, then sealed it against the nozzle of my vacuum cleaner. Worked well, but it was disappointing to realise how little suction the cleaner actually has - only about 5 inches of mercury.

Hi all,
I have just completed the water test on our home vacuum cleaner, an old Nilfisk. It pulled 87 inches of water in a hose with an inside diameter of 1". I divided the total of 87" by 13.6 ( 1" mercury = 13.6" water ) and got nearly 6.5" mercury. Not too bad for an old vacuum cleaner. I would assume using a smaller diameter hose on the vac table may give a little more pull. Judging by the footage Ive seen with others using vacuum cleaners with 4-5" mercury I think I will be happy to use the Nilfisk until it is required to do the household cleaning Smile Much cheaper than buying a proper vacuum pump.
