Learning resource for bolt timing

[Shawnba67]

i am aspiring to be a hobby gunsmith i.e. greener than pig squirt. I have chambered 5 barrels so far. My friend with high risk tolerance has talked me into attempting to silver solder a rem 700 bolt handle on for him. I only accepted this challenge because I can't completely ruin anything, at least without trying to(can't easily get to much heat at bolt head) Anyway can you guys point me to any good reference material to up my understanding of the entire process including timing of the bolt Thanks much Shawn

Have you ever silver brazed before?

Perfect that task before you attempt destroying your buddies bolt & handle!

Dan,we have pretty much all process welding capabilities here,been to school( a lot).

My OA torch is a touch big,it's used in lite/medium construction.....medium sized AIRCO.The welding tips het down to where I can do pretty good on 20g steel.

If needing to get rid of some money before the years end,might as well be at the local welding shop.What do you think of those really small Smith torches?

I always called'm jewelry torches.Not everything coming through our shop gets hit with Tig....small parts heating comes to mind.Anything better than those small Smith's?

Smith is too delicate. Get a Victor.

Victor torches.....SUCK & are dangerous.
All the black soot in the mixing handle is evidence of fire in the handle.
A loud whistle is your first clue.

My preference for a lightweight silver brazing torch is a Smith's Airliner.
tips to 0000
cutting head that is variable(no other line of torch has that capability)
rose buds.

The jewelers torches are too small for silver brazing firearms pieces/parts.

When that happens, it's time to replace the O-rings

Victor torches-
Victor tips/attachments need to be tightened w/a wrench or the whistling will commense.
Attach your flash suppressors/check valves at the torch when/if using a Victor.
Constructed of brass tubing & sheet metal,soldered together.
Nipple shaped tapered seat/seal.

Smith torches-
Smith tips/attachments can be finger tight & rotated during operation w/o issues.
I've never installed flash suppressors/check valves on a Smith torch or at the regulators.
Constructed of solid brass & nickel plated.
2 O rings & carbon seat/seal.
Cutting head that is variable,meaning oxygen pressure set at regulator to 60psi.
Cutting jet can be feathered to a few psi not the regulated 60psi at regulator.
No other cutting head/torch has this option.

Things have changed, Dan. Those "suppressors" are mandatory on all torches. I have never tightened the head to the mixing chamber on a Victor. Using a wrench distorts the O-ring on the handle, and also distorts the threads on the brass. That distortion causes leaks, and results in someone cranking down on a wrench to stop the leak, which results in further damage. I have witnessed the same thing when tightening the gauge to the cylinders. Cranking it down to the point the connection leaks. Pressure is always adjusted at the regulator. Unless one is cutting through very thick material, more than 40 lbs of pressure is never needed. The amount of pressure at the tip is easily controlled with your thumb pressure on the trigger. It all comes down to personal preference. In a small one man shop, the Smith works just fine. It's a great torch! Having worked as a Union Ironworker and Union PF-Welder for all of my working career, I have a little bit of hands on experience with the use of a torch, whether cutting through 6" of solid material on steam generator whip restraints, or, slicing fractions of an inch from .065 wall tubing.
