I had a busy & productive weekend for the boat! it started 9:00 Friday morning after Christmas when I dragged the remains of our house's old oil fired forced hot air furnace up to a friends' house. (They are dairy farmers & he has a good workshop for repairing the tractors & farm equip.) I used his cutting torch, electric shears, & grinder to cut the old heat exchanger from our house's old oil fired forced hot air furnace up into about eight pieces, which I then brought back home to weld back together to use as a boiler for steaming. (I guess it was kind of good that the house needed a new furnace this winter :rolleyes: ) Saturday I welded the pieces back together & got it pretty much together. - My idea had been to reduce the size of the heat exchanger to as small as I could, cut a big circle out of the top & suspend an old 35lb propane tank in the fire box area to boil the water in. Well, it turned out better than I expected and Sunday afternoon I was making steam! I even hooked up the old controller so that it uses the safety shut off (in case the flame goes out), and starts with the simple push of a button.
When I got that finished I set up my steam box (10"x10"x12') and within about 15 minutes of a 'cold start' I had enough steam in the box to bend anything you could want to. (With about 100,000 BTU it better make enough steam!! LOL) With the warm weather we had this weekend I though I'd give it a try, so I took one of my 10 foot oak planks, planed it, ripped it, & jointed it into five ribs each 3/4"x7/8" x10' & tossed them in the box. An hour later (didn't need to wait quite that long) I was bending ribs! Five out of five good ones, and they went in better than I could have ever hoped for! Kind of like butter!! (Can you tell I'm pretty pleased?) they went in so nicely & I had that much working time that I'm confident I'll be able to get them all in without having to wait for spring weather.
I used about 1 1/2 gallons of heating oil and had to add about 3 gallons of water half way through, but it recovers so quickly that steam never stopped coming out of the box.
OH, I guess I better order some rivets. LOL
