I've got a few figures converted to make moulds from and rather than just go to the expence of getting them made I thought I'd have another go with a Tiranti mould for some of them. Now, these moulds are soft and break easily but I had some old rubber lying around... enough for one mould - thought, why not see if it still works? If it doesn't, no great loss except time and I'll just reclaim/repair the conversions and revert to Plan A - limited having a couple of new moulds made. If it works, perhaps do a couple more Tiranti moulds for figures I only need a few of.
On the other hand, making moulds is very (as in 'very') messy!

| This is the first half done. Needs cleaning up a lot - bits of rubber and plasicene to be trimmed and removed - but at least the rubber sems good and none of the bayonets have sprung away from the rubber. This is an issue if you're making spears or anything - if the tip springs out it's impossible to get back in place fully and the figure is ruined. Anyway, time to clean this up and go for the second half. |
As an aside, getting a few anon span comments - bit of a pain deleting them and they are appearing on previous rather than current posts. As the person putting them on doesn't realise that I'm notified of new comments and first look for them in the comments part of the admin section and just delete them from there... I keep telling blogger they're spam, it hasn't taken the hint yet.
I've never seen a Tiranti mould - it does look messy! Years ago I used to make drop-cast moulds using Tiranti RTV (root temp vulcanizing) rubber - which was how we used to make masters from wax or plasticine originals - I'm guessing this is a similar material.
ReplyDeleteIt's Tiranti RTV-101 rubber. Tears easily, so undercuts don't last long, some of the plasicene still sticks however much wax you use, so it takes an age to clean it away, plus you can't make perfect seals so have to cut away excess rubber... I tend to pour the rubber/catalyst mix cold, spin the mould to try and get rid of air bubbles, etc, leave a while, then stick everything in the oven at just under 100 to post cure -with possibly a higher temperature boost late on!
ReplyDeleteLooks messy indeed! I find the comments section in admin a godsend for deleting spam, makes it an easy task.
ReplyDeleteYou want to see my workbench as well... yes, comments section works well, happily only a few a day.
