Hi Jerry, get a cheap toaster oven and preheat your molds for an hour or so at 150-200 degrees and it will rapidly increase the set up. You will also get extra...
I'm doing more and more spin casting these days and was wondering if anyone knew a few items other than GS, Brown stuff, apoxie sculpt, miliput, magic sculpt,...
This is my first post. I need to cast two 14" wheels. I need something that will be machineable on a lathe, and something as duriable as aluminium. What...
If you use a low temp silicone like the NICEM green, you can vulcanize plastic card, most resins and some waxes. I routinely vulcanize SC300 from SmoothOn...
Bandsaw wheels? I use aluminum, specifically wheelium (remelted auto wheels). One of the Zamac (zinc) alloys would work. A rigid casting plastic would be...
Thank you. I was trying to avoid that material but seems I'm going to need it. :) I buy all my rubber from Conley for vulcanizing. I had no idea smooth on made...
I apparently wasn't clear. SC300 is the smooth on resin that I make resin masters with. The resin is made by SmoothOn not the rubber. The rubber is made by...
OK, now I think I understand what you meant. A master is made by whatever material, then an RTV mold made and a resin master is cast. The resin master is then...
Correct. The semantics are confusing. When I make a mold of a master part, I refer to vulcanizing it even though it is the rubber that is being vulcanized....
Got it!!! This is very useful information. I design model kits for a manufacturer and often create masters which I cast in resin, usually Smooth On 300 or ...
I spoke with a metal caster some time ago who said that adding the aluminum powder to the polyurethane resin helps it to take the heat better when you do this....
I just thought I'd share something I found casting plastics that can be remelted. I've been searching for a long, long time to do this and found a few very...
Hi Dave, I have used these but also I have used brass from old discardrd bracletts and these are better at welding together. we have 4 cats and 2 dogs for...
Great idea but my parts are 1-2mm thick at times and need the cps to be the lowest possible for flow. I've tried thicker resins but the surface tension still...
Hi, The product thatyou are looking for is a mousse like substance which can be welded into different surfaces and shapes. I used this at chirstmas to make...
Thanks, but is there a clue to what this product is called? Is it a pourable foam etc? It sounds like this may be what I'm after. Regards Andrea Australia...
What kind of thermoplastic were you trying to use? Almost all thermoplastics melt into a gooey mass that needs a lot of pressure to move into a mold, which is...
Andrea, Our Dragon Skin 10 silicone is very popular for this type of project. It can be purchased through: Rowe Trading 4 Holder Ave. Richmond South Australia...
I need help finding a non-conducting material I can use to cast a very thin, small part. The part is about half a millimeter thick, and needs to be about as...
Michael, You can cast some pretty thin parts in resin. I've spincast many in alumilite. Some are about .020" thick which is roughly .5mm. As for strength,...
What is the best way to cut a 1/2" thick piece of lexan? I was going to buy it by size online but since I can't find a 14" x 14" piece of it, and I don't want...
I use a 4 TPI blade in a jig saw or use a standard carbide blade in a table saw. I use both at work at at shop for lexan. Just be sure it is lexan and not...
Forgive me, but what is a standard carbide blade. I am pretty sure I saw a bunch of different ones at Home Depot tonight. I found this.. looks like they want a...
I cut Lexan all the time for mold boxes, and I use my table saw equipped with a 10" 80-tooth carbide-tipped blade. The blade is for extra-fine finish cuts on...
Same atomic components, different molecules...... Plexiglass versus Lexan ........ One shatters much easier than the other. Or Water versus Heavy Water...........
In a pinch, or if you're short on cash, you can get a cheap, (about $5.99) fine-toothed plywood blade for your table saw and it will cut your Lexan but won't...
