I’m always on the lookout for new resources for GF supplies and have collected a pretty fair-sized database. One that I (and others) have mentioned is www.cherrytreetoys.com , I’ve used them frequently for 1/8” hardwood plywood in cherry, walnut, mahogany, oak, maple, & birch. They even have 1/16” and 1/32” birch plywood. I do appreciate that the sheets are 16”x24”, so that I can cut to get “short grained” sheets that are near GF bed size (12”x16”).
I’ve ordered online, but the website looks/feels a little clunky to me. On my last order, they sent along a paper catalog. It’s better organized and well illustrated – making me take a look at their other offerings. They obviously sell to anyone, but they seem to be oriented to the scroll-saw crowd, which is in reality, the GF community also. This is important to me, since not all companies I order from are geared toward home hobbiest/craftsmen. (“Whata’ya mean, you want less than a freight car load of veneer?”)
They have 1/8” and ¼” hardwood lumber, hardware items like hinges and latches along with plenty of finishing supplies. They also have a wide selection of wood-turned items that just can’t be created on the GF, like spindles, finials, balls, etc. Bunch of clock movements too. Everything is geared toward GF-sized projects.
I would urge anyone interested in using the GF for more than just cutting and engraving proof-grade flat projects, to get a copy of the cherry tree print catalog. Reasonable prices.
