Strength training weight stack pin with an additional ring, photo 1 by Don Tai
This is a strength training machine weight stack pin from a city gym that needed some alterations. I enlarged the hole on the handle to add a ring. The steel of the ring was from a garage door spring, so is high strength steel. I then bent the ring to allow the pin head to be threaded, bent the ring back into alignment, and then welded it shut. I used SMAW 6013 at 40 amps, but should have used 70amps.
The ring is 1/4″ 6mm thick and is not easily bent. I cut the garage door spring lengthwise, resulting in many rings, but they are slightly twisted. These then need to be bent into alignment. My welding is a work in progress, meaning I need a lot of improvement. Welding rings is interesting because you cannot get an angle grinder into the middle of the ring.
Beto bicycle floor pump V1, early version, bought at MEC in Toronto. The pin in the valve head broke. Photo By Don Tai
Bought from MEC a decade ago for $25CAD, this pump has served me well pumping up kids schrader low pressure tires, as well as the odd presta style. A litle bit of inattention from the Big Weed and she broke the valve head. Specifically the plastic pin that holds down the valve head to the valve. A repair was in order.
