How to make a TRP(Tension Release Pin) continued

Peg wins the prize.  She advised that I smash the head of the nail.  I did.  I got out my hammer and I smashed it using Steven's sledge hammer as the anvil.  It worked.

 My only concern is that the smashed head, while the correct shape, is a bit big.

It could interfere with function.  I must experiment with trimming.  Good thing those nails are cheap.

How to make a TRP (Tension Release Pin)

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.

Recently, a reader emailed me about the tension release pin on a Singer 301.  I promised that I would cut  a TRP to the correct size and send it off in the USPS.  I finally got to it today.

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 cut off the sharp end and filed it down so that is was smooth.  Then I lined up the two pins next to each other in the  nippers

 And cut it to size.

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.
