Kotona taas
Talviloma. Englanti on nyt loppu. Tällaisella kuljetaan vaihteeksi:
This is the story of my chop shop bike. I got this old Tunturi VIP from a cycling buddy in Oulu. It is way too big for me and made from solid non-butted steel tubes. Perfect for chopping. After disassembling the bike I first chopped off the rear triangle. I drilled a hole through a 120mm wide block of wood and drove a long 10mm bolt through to keep my new tracks drops in place. Then I fastened that block of wood to a solid welding table and positioned the rest of the frame accordingly and welded the rear triangle parts back on. For welding the tubing I cut small blocks of wood of different heights, two blocks for each tube diameter, top tube, head tube etc. When I position the tubes on the blocks on a flat surface all the tubes will be at correct height in relation to each other eg. the center lines of all the tubes are at same level. After that it is easy to weld everything back together. I did not do much mitering, just roughly checked that everything goes together. Mig welding will allow you to fill in small gaps easily, which might not be good for strength, but who cares, it is not a BMX bike. This will be a quasi scientific experiment on if my welding is good enough.
The bike is now in rideable condition, I will paint the frame after I have filed the welds flatter. The seat tube is maybe too upright, I had to bend the seat post a little backwards. Next time I will make it more laid back. This was a nice excercise to show that turning a fauber-crank beater into a track-ish beer hauling superbike is possible in five hours with an angle grinder and a MIG welding machine.
