Here is my high tech steambox setup. The cedar strips for the canoe are easily bent over the forms but the laminations for the stems at each end of the boat need to be steamed to be bent around the stem molds. I did a little test run last night to make sure my PVC pipe wouldn’t melt on me when I actually steam the wood. I scored the teapot at a thrift store for $6 and the PVC pipe was $6 at the local lumber store. I already had the burner and a few cans of butane in the garage. For the test I just shoved some rags in the top and set the pipe on the spout of the teapot. Before steaming the stem laminations I am going to put a little block of wood on the bottom for the strips to rest on and secure the top a little better. I was thinking of trying to use a funnel on the bottom so as the steam condenses it will drip back down into the teapot instead of the ground. It makes pretty good steam even outside on a cold night so should work great when it’s in the shop.
Once bent the stems are laminated with epoxy. I was all excited and made a run to a marine store on the waterfront for some epoxy and found that I was going to have to wait a while. The epoxy and hardener for the whole boat is about $150. I thought they might have a small kit just so I could glue the stem laminations together but if you want less than a gallon of epoxy the price pretty much doubles. Rather than spend ~$70 for a quarter gallon I’ll wait and spend the $150 on a whole gallon. I’m hoping I can sell the lumber rack taking up precious floor space in my shop for a decent price to help pay for the epoxy pretty soon.
