Perhaps I am misunderstanding this. When I think of bronze weld, I think of tig welding using silicone bronze and shielding gas. When I think of brazing I think of oxy-acet torch, bronze rod and flux. Both are capable of making strong joints. Harley Davidson used to braze their frames together.Bronze weld. Brazing is for slip joints.
I had a similar experience but with less catastrophic consequence. The interlock lever was broken but was easily repaired and no further problems.

Yep, that's exactly the part and area. If I had to fix it on my own, my plan would be to remake the circular part on the lathe, mill a flat on it and on the surviving cast iron, then either pin or bolt them together!I mostly use Low Fuming Bronze, with StaySilv Black Flux and this stuff is crazy strong just as strong as a weld in most cases.... I also do Tig brazing but its very easy to get the metal to hot, gas brazing is very forgiving....
During WW2 the USA was gas welding air planes together and the UK was gas brazing their planes.... Both are strong enough to fly!
Is this the part that is broken? The end of the gear selector handle? We maybe be able to just make a new tube then pin and braze it on the handle....

Hello Chuck,Perhaps I am misunderstanding this. When I think of bronze weld, I think of tig welding using silicone bronze and shielding gas.

Note* Having had a little rant about terminology I mucked up. Should have written Welch and not Welsh. Probably comes from mixing up ancestry with a family name so apologies for that.
It would be interesting to see historical examples which show the advances of lathe abilities as they came into being. My guess is that half nuts came into use before power feeds. At some point power feed was added to a lathe with half nuts and within about the first 15 minutes of use someone managed to engage both at the same time and break the machine. The lockouts probably came into being because the manufacturer was getting complaints about machines breaking for exactly this reason and wanted to stop the nasty telegrams.Just about every lathe that has multiple feeds has interlocks to prevent you from engaging more than one feed at once. Even really old lathes. If it once had one, and it is broken or something, it should be repaired so parts do not get destroyed by engaging more than one at the same time. Don't just fix it, try to fix it so it can't happen again...
On second thought, looked up Reed-Prentice, formed in 1912, that is perhaps old enough to be when machines did not have to be smarter than people.
Agreed, my original comment was tongue in cheek. The reality is Murphy's Law (Anything that CAN go wrong eventually WILL go wrong.) No matter how good we think we are, we all make mistakes.In other words, the intelligence of the user has very little to do with things going sideways.
