Victor Ignitor Repair

[Rex Piekarczyk]

What we have here is a Victor ignitor that has been treated unkindly. I wanted to drill and thread the trip finger pin hole large enough to thread in a larger plug, then thread the plug for the pin. The problem with that is the existing hole is too close to the wall of the part that goes into the cylinder. Option 2 is to drill, thread, and plug just short of the depth of the mounting flange. Would welding or brazing be better or would that be a porous mess?

What would work best way to fill the series of small spring anchor holes? Pins filed flush?

Braze it up Rex......lay on NEARLY on its side so the filler metal will go all the way to the bottom and displace the flux so you get a nice solid repair.......

I'm curious........why do you want to fill the spring holes?
If you decide to braze the other hole you might as well open those holes a touch and braze them too while you're at it.

My goal was to have a solid repair made so it looked like it wasn't repaired. I'll put the sleeve & spring back on, they may cover those extra holes

I'll make a trial brazing on a test part. I've tried to gas weld deep holes before and found that the flame snuffed out in the bottom.

This is a cast iron piece, but due to its solid shape I don't think I need to do the whole preheat/cooldown bit do I?

With a hole like that, stay off center with the torch and use the force of the flame to push the filler material to the bottom. That's not a large piece so getting the whole thing to red heat will be easy.
I very seldom used a brazing tip except for small parts.......I always used a cutting tip to get the job done in a hurry......

Victor ignitor is back in service.

The wallowed out hole was plugged, filled, milled and tapped.

Extra spring anchor holes were drilled and filled with press fit pins.

A new outer sleeve was cut from cold rolled bar stock.

Replacement springs had @ 4 too many windings and had to be trimmed to fit.

A new #0 taper pin was turned from cold rolled bar since I couldn't find anyone to sell me less than 100.

Thanks for all the advice for this project.
