Tonight I got a few things done.- Sanded and primed my son's Darth Mauled deck.
- Pasted up a few broken deck signs.
- Made a new mold for casting clear resin wheels for my 'Bling Is Dead' piece.
Here's a couple of photos of the process on the ghetto mold making.
Chris Ryniak told me I could make a 'dump mold' for my needs. I picked up some alginate for the mold and some clear casting resin only to find out that you can't use alginate as water and resin don't mix.Finding professional grade stuff locally here in Cleveland is like finding the secret to happiness. Add to that the fact that I have a lot I want to do on a VERY limited budget and timeframe and you get all the makings of a MacGuyver episode.
RTV molding silicone is expensive so after a little interweb research I found out you can make a mold from silicone caulk. It's generally frowned upon by people who know what they're doing... but since I don't, full speed ahead to Home Depot!
To sum it up, you brush on a coat of silicone onto the part you want to mold. Let that cure. Then the wierdness begins.
Get your hands wet with dish washing liquid soapy water, squirt some silicone into a bucket of water and knead it. You're basically rinsing out some of the chemicals which I assume slow the curing process and make the silicone all sticky and gross.
The rinsed silicone comes out of the water like a thick jelly. Just mold that goop around the part (which you put down on something smooth) and build up your mold. You end up with something like this. There's a skateboard wheel in there somewhere...
Time for some trimming because I'm impatient!
At the risk of ruining the mold I decided to let it cure overnight and blog to keep my mind off the fact that I want to pull the master out, mix up some resin and start casting!
Stay tuned and get those decks done! Just make it up as you go along. It's what I do. :)

ReplyDeleteif you said you were eating cupcakes I would have cut you some slack because in a convoluted way it would have been related to your deck.
