Fascinating stuff as usual Bob.

Hi Robert. Can't you use a spot welder to weld the feet on?

Hi Robert. Can't you use a spot welder to weld the feet on?

I take it that large commercial outfits use spot welding. However, I've never done any welding, just brazing and soldering, don't have any welding equipment, and (with the Stay Brite solder) the soldered joint is mechanically strong enough.

Best wishes,
Bob

Something like that, yes. Here's what would be good.

Hey Robert, with your skills you could make one like the guy in the YouTube link!

Perhaps. But then there is the jig, the attempts to get the correct pulse, etc. Thanks for the suggestion, but I'll pass on this one.

Hope I didn't cause offence? It's probably far more complex than I surmised.

Not at all. I'm happy to consider suggestions, but, since I'm the one doing the work, I get the final choice of method. ;)

Best wishes,

One of the final pieces of the puzzle is now in place. Getting the dial feet to line up has always been tricky. I wanted a very precise jig, and remembered that I had an extra, little frame for a staking set. I used some strong double sided tape to attach the staking frame to the base. (I might use some strong acrylic adhesive, if the double sided tape proves inadequate.) I made a "punch" to hold the wire for the dial feet. The punch is brass with a hardwood insert. The brass provides rigidity, and the hardwood insert, which is nearly sacrificial, gives some electrical and heat insulation for the staking frame. A bit of paper under the dial also provides some electrical insulation. It works really well. :)



Best wishes,

Wow! Incredible Bob.

Your eye for detail and exactitude is so impressive to a clod like me.

Love reading your stuff.

Cheers, Neil. I do think that I give new meaning to the "trial and error" method of investigation, especially the error part. But, I keep plugging away.
