Tig on Cast, part was room temporature, used quite a different approach.

[vicegrip]

Not certain "Cast" what ?
Malluable, ductile, grey? etc. etc.
It was cast from original patterns decades old.

A 1.38" endmill start was way out of position. My guess, a collision
while travercing. Note; on one-offs, and work worth a month's wages
travence with the spindle OFF! Goes for large lathe-work too.

Babbitt and phenolic in the region, part is done.
NO preheat allowed, nor heat-build-up.
Knew it was on the schedual so had time to rehearce (in the mind).

Took pointers from several other discaplines.
I've been told over the years to get as comfortable welding while standing
as sitting doing repairs and/or tool welding. Always made excuses to avoid standing.
Had little choice so, remembering advice to brainstorm, phone-interview
and the like standing, for sharper mental focuss I went for it.

I knew I'd have to do rapid targetted peening with no helper.
A Blacksmith book from the 1800's advises a 1/4 turn pivot
no greater than one step, for moving form op to op with a peice
that cools quickly, and have your tools sittuated smartly.
So hammer, punch, and wire brush were on the bench to my left,
not on the part.

Used conventional helmet, Tiger-hood, and scratch-start and no glasses (correction)
I wanted to be in close harmony to the work so-to-speak.
I tend baddly to weld too far with tig, when a deposition goes right where I want it.
You can quickly loosen Babbitt or char Phenolic that way, SO
I discaplined my mindset and rehearced this for a while.

Peening is second nature for me, many ways, many reasons, many uses.
Welding is not; hence all this effort.

I could touch the weld after each peening. Felt no warmer than say 130 degrees.
It worked better than I ever dreamed of. Got Pics but I'm fading fast.
I can sleep now that I have unloaded my Geeked Excitement.
I'll put em up later if any interest is generated.
Cheers and G'nite.

I'd like to see a couple of pictures when you have the time and energy. I love it when you plan and think and rethink and it works exactly as you imagined. Agree with careful positioning of the tools; sometimes you have to strike while the iron is hot and cannot be looking or fumbling for a tool.

I'm also interested in hearing how you solved this problem. The "conventional" wisdom serves us well 98% of the time. It's when it DOESN'T and you have to think unconventionally, that the real talent comes to the fore. We can all learn something from this.

Well the pics R in a text/mail to the PC .........
Some more shut-eye, check to see if cropping will be needed
(.........sometimes the propriatary "thing" ya know .......... )

Have a Good 1

Incidently tuesday I also managed to allow my cell to go on it's final voyage
into the City's trash collection

At least the 30$ used one I got at US Cellular takes good pics 4 a cellFone

time-crunched still, so Xplanations Latr

,,,,,,,,,,,,,,,
Oh yeah, the phenolic is under the banding held by the stainless hose-clamp.
I used to use "stick" for such repairs, may not have needed to sheild it,
this worked so well, using tig.

Ya coulda filled that with Bondo! Good job.
