Re: Bearing issue?

Sounds a bit like chip welding where a small chip welds itself to the cutting edge of the tool for a short duration and then breaks free.

Re: Repairing a cast brass part

I did it back in the 80's when I had discovered Silicone Bronze filler rod for TIG brazing steel. It was only an experiment, as I had a short piece of 2" brass tubing and a small piece of brass sheet and wondered what would happen if I tried welding them together. It worked pretty well as I was able...

Re: Repairing a cast brass part

I've TIG welded brass using silicone bronze filler rod so that may be an option depending on the repair needed.

Re: Floating reamer holder

I'm not yet too familiar with them, but have a Smith Tool floating reamer holder that I'm not quite tooled up enough to use yet that will allow .030" radial misalignment, but it does not compensate for angular misalignment.

That's where things can still go bad when using one it seems.

Re: Floating reamer holder

That wouldn't show vertical error in the tailstock axial alignment either parallel or angular.

Re: 1911 Project

A gauge pin was then inserted into the barrel bore and indicated concentric to the lathe spindle axis. https://i.imgur.com/nONBiCil.jpg The reamer was then plunged to the desired chamber depth. https://i.imgur.com/jTJBsogl.jpg The barrel was then flipped around and the crown was cut using the same t...

Re: 1911 Project

Finally had some time to tinker. Plugged the lathe spindle and turned the plug to just slide into the barrel. https://i.imgur.com/oo1KjUEl.jpg Took a boring bar holder and indicated parallel to the Z axis and plugged it with round bar. Then indicated the round bar in so that it was concentric with t...

Re: Buying a 4 jaw chuck

It's a bit confusing, as your title states a four jaw chuck, but them you quote runout specs.

Are you looking at four jaw scroll chucks?

You should be looking for a four jaw independent chuck for chambering use, not a scroll chuck.

Pistol or rifle barrel?

Re: Trying to prevent ribbing on tapers

I'm in total agreement with Mauro, but I'd also try a smaller radius on the tool. Maybe about half of the radius you are using to start.

Re: NEWLY-ACQUIRED JET 1236PS

I remember seeing images of the machine being lowered through the hole in the roof/house.
