A while back I was working on a machine that needed a tension release pin. I can't remember what machine or why it needed a pin. I think, actually, that the machine had a pin, but I wanted one a little bit longer.
I had some small nails that looked to be just about the right size. So I got out the nippers and cut one to size. It worked quite well.
I took the tension assembly out of the Singer 301A long bed that I bought last spring. I had performed some aluminum rot surgery on it then and never really finished that job. I have yet to prime and paint it. But the surgery was apparently a success. No evidence of further corrosion. At least on this spot. Since the weather is going to be nice this weekend I think that I will finish this job and prime and paint the repairs. Don't know why I didn't do it in the first place...
TRPs have a darling little nub on one end that prevents the pin from falling out of the tension assembly. I cannot replicate that nub, so when using a custom made TRP, one must be careful not to let it fall out.
The TRP is 1 1/8 inches long.
The nail is 1 1/2 inches long
I stuck the nippers and nail inside a large yogurt container when I cut the nail. That prevented the nail and cut piece from ricocheting around the shop. I did not do that when I cut off the sharp point. Luckily the nail didn't fly far. Who knows where that little pointed sharp piece is.
I did have to cut the nail again because the first time I didn't get it short enough. Better that than the other way, eh?
This pin will fall out of the tension assembly, unfortunately. I guess one could put a tiny little dollop of JB Weld on one end to prevent that. Hmmm may have to try that.
