Toaster ovens are available on the second hand market for cheap. :)
Look for the little triangles symbols with a 2 inside. Lots of pretty colors.

However, I already ordered a 12” x 24” form so I don’t need it anymore. I am going to pour a one-off (for me) what I call a Turkey size cutting board (maybe 18” or 20” W by 30ish” L) I looked at the ¾” x 24” x 48” and it’s $127. In this case, even a disposable form is much cheaper.

I can only get HDPE sheets from Grainger’s (that I know of – big box doesn’t have the thickness). Given I have to make my form anyway, that’s an option. The “con” is you still have to treat it like any other form (i.e. assembling & caulking). I like the self-contained ones like in your link but the “con” of that is then it truly is only for one size (i.e. not reconfigurable). This Canadian company (Jeff Mack Supply https://jeffmacksupply.com/en-us ) has several sizes. I just ordered the 12x24. I wanted something a little bigger than the Amazon one since these will be charcuterie/cutting boards. The only way I can justify the expense is I’m telling myself I’m making multiple gifts! I’m still going to make a form as outlined below, using mold release. I want to see if this works which then frees me up for other form sizes at less cost in the future.

Now I want to make cutting boards for Christmas gifts in the river style. They will all be the same dimension with only the “river” being unique. My question is can you reuse forms?

I’ll use caulk along the natural edge to try to keep the resin contained but I’m sure I’ll have some leaks which is why I’ll spray the whole base. Do I need mold release tape? If so, river bed only or whole base & sides? For reuse, peel it all off and retape? Or, is mold release spray good enough?
