I completed the welding of pF’s frame! Next post should show the assembled frame and front end.<\/p>\n

Tubing for the fork came from the chain stays of an old road bike frame. A wedge was cut from the tubing, and then it was bent and welded. The dropouts are 0.188″ steel cutouts inserted in welded into the end of the tubing.<\/p>\n

The picture below shows the beginning of a thrown together jig to hold all the tubing correctly for welding. In the end, a lot of it was just eyeballed, but it should be close enough.<\/p>\n

lots of messy welds are hopefully still pretty strong<\/figcaption><\/figure>\n

The welds got better with time, but the first few were rough.<\/p>\n

Tape is a great way to hold things in place for a tack weld, although you have to be sure to clean off the adhesive residue. I would be curious to hear if others have better tricks to do this.<\/p>\n

The brackets on the head tube are for strength and decoration. The aluminum piece on the side will eventually screw on to the smaller bracket as a bottle opener. I guess I don’t drink much, but it should be fun to have. I chose a separate aluminum piece so that there would be less chance of damaging the paint on the frame.<\/p>\n","protected":false},"excerpt":{"rendered":"
