So for a while I've been agonizing about what to do with my Mini Mental Block casting stuff that I've had sitting around in the house now for some years. I'm certainly never making a Mental Block like this again so why not pitch my discarded wares on eBay!

http://cgi.ebay.com/ws/eBayISAPI.dll?Vi ... 0025914736

So there you have it. For those among you with the righteous testicular fortitude to attempt to cast your own mini mental block, I've provided as many pieces as I can to help ease the task of making such a puzzle.

I can't imagine it to be a particular popular seller (most people prefer buying complete puzzles, not DIY kits that aren't simple assemblies) so I'd imagine it'll go cheap. Enjoy!

I'm very tempted, but it would be a first adventure into molding and casting.

If you were making a mental block now, would you use the plastic sheet instead of casting it?

I make my mini-mentals out of built-up milliput. This looks like a better way though. Might be worth it if Mefferts started to produce the mini-skewb again.

I use the plastic sheet method. So far I've only built three mini mental blocks. My prototype there was cast using Synair's Pour-a-Kast two part polyurethane which apparently they no longer manufacture. Probably because it wasn't very "hobby" friendly.

The next two mini mental blocks were only made with the plastic sheet/block method of cutting/shaping sanding pieces to the appropriate dimension which suits my style a lot better.

If I had to choose between casting and using an epoxy putty like black Milliput I would definitely go with casting again using a clear resin and black liquid pigment in a squeeze bottle. Aside from getting much more consistent puzzles if your masters are good, the process will yield a much more durable puzzle that's impact resistant and wont' chip or shatter like epoxy putties will. Weight-wise they'd probably be about the same. The polyurethane is probably a bit lighter.

I certainly won't be making mini mental blocks with this method again, but I am considering employing resins again for a future project or two which are much more difficult to shape by hand out of raw ABS plastic stock.

Do you think they would sell plastic sheets at home depot or ace, etc? I want to learn how to use plastic sheet because now, the only thing I use is apoxie sculpt and I find it time consuming. Also, any tips on the sheet method

Thanks

They don't sell the plastic sheet you need at places like home depot, no. You need to locate an industrial plastic company that sells to the public. Here's the one I go to occasionally on my way to work:

This isn't really the thread for discussing plastic sheet though. :)

If you want to start a thread on the main forum I'd be happy to give whatever advice I can give.
