No I didn't use a release agent, it was some car body filler from Halfords in the UK: Halfords | David's ISOPON P38 Easy Sand 250ml

Thank you for the info mate. Just finished applying my PVA coats which I started at 9am. Few more steps then it's the exciting bit, well exciting for me as I am sure you must be getting pretty bored of making moulds now.
Love the new boot vid and looking forward to seeing the heals on now

i red that your repsil silicone 's hardness is e30 but does a 25 A should be ok ? also how much silicon did you need to make your molds ?

Yep anything around 25-30 should be ok for general moulding. Each shin and thigh piece was 5Kg of silicone, so around 50+ Kg for the whole suit.

50 ?! omg ok then but what would happen if i would put less than 5kg per shins ; like less coat of silicone ?

Then your mould wouldn't be as good quality and you risk making worse casts.

The mobility of these is fantastic! The best ive seen and the motion looks as good as the cgi Iron Man!

I do wonder a couple of things though. Why the need for the hinged toe sections, and how will you address the gaps that the moving armour plates reveal?

The toe sections are there for effect only - the plan is to attempt to build a machine which places the pieces on the exoskeleton/wearer, so having it flip the toes over will look nice.

I have various other parts to make out of sheet material such as the heel pieces, so there will be other inner layers and bits of metal to add effect to the appearance.

nice work buddy! what thickness foam do you use?

The original foam build was 10mm thick for all of it.

Here's a video from me, fiberglassing my thigh pieces, with lots of discussion: XRobots - Iron Man Armour Thighs Part 1, Fiberglass hand lay-up with polyester resin and gelcoat - YouTube

Re: XRobots Iron Man Mk6 UPDATED: Fiberglassing thighs video added

omarbou1, something that might work to same money on silicone: use a thin, carefully applied layer or 2 of the moulding silicone, and then use silicone caulking on top of that. It's usually quite a bit cheaper, but if you know how to use it, it can work decently.

I am not, however, an expert in moulding and casting. I imagine that XRobots' method is going to give the best results with the cleanest casts, and the moulds will probably last longer. But it might work to save some money on expensive moulding silicone.

I've seen people using caulking for moulding, but I'm not sure if it's actually a good economy. In the UK a 300ml tube of Silicone Sealant is about £6 so it about £20 per Kg. You can buy moulding silicone for less than that on eBay, and even less per Kg in bigger kits. I guess you could get cheaper caulking in bulk, but it's still going to be hit and miss since it cures in air rather than with a catalyst, so the cure is not as predictable. You'd also have to do a test to see how well it sticks to any initial costs of moulding silicone.

I suppose it comes down to your commitment and purpose of making the mould.

Amazing work on thighs!

Re: XRobots Iron Man Mk6 UPDATED: Fiberglassing thighs video added

Great job on everything you've done thus far. I really like the exo-skeleton idea. I read through most of your thread and skimmed through the last few pages looking for what you used to cut your foam but couldn't find anything on it. Did you use a heat knife, exacto knife maybe? Thanks for any info you can give me.

Re: XRobots Iron Man Mk6 UPDATED: Fiberglassing thighs video added

Here are some pictures of the raw casts for both thighs. They are probably the worst pieces of all - remember they were moulded from foam versions, which has meant there are some distortions in them. I have a lot of fixing up to do.

You can see pictures of all the rigid pieces here: Iron Man MkVI Armour - Rigid Parts

It's much cheaper in the USA. 9.8oz tube (280ml) is about $4.50, or £2.78. So about £10 per Kg. And to make it cure, just knead it under warm soapy water for a minute; it starts to get a bit less liquid, and after it sets in about 15 minutes. Works decently. Still lower quality than the proper ways you're using.
