[quote=charlescarlis]We did that metal shop thing too - had a foundry an dwore pure asbestos aprons... We cast eagles, then cleaned them up. They stopped that part of metal shop when they were pouring aluminum one day, it was raining outside and water dripped into the ladle of aluminum. Blew up, scattering molten aluminum all over the shop. Luckily only minor burns, but the kids pouring were splattered real good all over their PPE, but weren't hurt at all as I recall.
That, however brings up an issue; I imagine Hobie has to be pretty aggressive about protecting their copyrights and patents, though many may have expired by now. I guess if you "improve" on the design somewhat you could supply an aftermarket, though small as it might be. Cottage industry.[/quote]
