Welding repairs and fabrication

-
Of the things I commonly fix or repair are things like stripped pedal threads in old cranks. ( Most all have been TOC hard to find cranks. ) I machine an insert slug to size and drill the end of the crank arm out. I use a Bridgeport milling machine to drill the crank arm so keep it as square as possible.

I install the insert. If all goes well this is a press fit.

I then weld both sides of the insert.

I finish the welds off. Tap the hole to proper pedal size in this case 1/2-20. Then I re-patina the repair area if so desired.

Finished and pedal test fitted.

Yes.
This is a TOC Jenkins frame I just aquired. The tubes in the triangle are a little worse for wear. The down tube had a section of new tubing cobbled in it that was the wrong size and was crudely welded. I believe the bike frame was also used to drive rail road spikes at one time by the amount of dents that were in the top and seat tube. The rear chain and seat stays are in good order but the tubes of the main triangle are rough to say the least. The easiest fix for a straight tube frame such as this is to put sections of new tubing in. Here's a before pic of the down tube repair.

I cut the old 1 inch undersized tube out and cleaned off the remnants of its remains from inside tends of the original tube.

I fitted th he new tube and fixtures the bike frame so I could keep the tubes inline.

I welded the tube in place then finished the welds.

I'm putting a section in the top tube the using the same method.
Beautiful craftsmanship!!!
