Re: plugging a barrel for bluing ....

epanzella, I may get in touch with you if you don't mind. I am re-learning to rust blue for a friend who has an old Marlin and doesn't want it "DuLited" ie commercial black. gunner312, if you are still around, I'd like to thank you on recommending the John Traister's book, "Professional Care and Fi...

Hey, I saw a sniper curve a bullet around a building by swinging the muzzle and hitting someone a mile away. That's Hollywood!

Re: plugging a barrel for bluing ....

I use only rust bluing. Plug the ends with dowels, coat the barrel with solution, let rust for 2 hours, boil in distilled water, card off. Repeat as necessary. I always do it 4 times but the 4th time is usually unnecessary as it gets fully dark after 3. I just like insurance. Change the water after ...

Do you have 60tpi on the gearbox and can you change some gears to cut the leadscrew speed in half?

Steve
To turn 60tpi into 30 tpi you have to double the speed of the leadscrew.

Re: Lathe setup question(s)

First you have to check the alignment of the headstock to the bed independent of the tailstock. This can be done with a ground rod in a collet or a test bar. I use an MT5 test bar the plugs right into the spindle bore with no other attachments or parts to degrade accuracy. Best $100.oo I ever spent....

Re: Why 27 TPI?

With the right change gears you can do 27TPI on just about any lath. On my Grizzly 18TPI calls for a 40T gear mating with a 40T gear. If I leave the QCGB set at 18TPI and change one of the gears to 60T(40T to 60T) I get 27TPI. 18 divided by (40/40) = 18. 18 divided by (40/60) = 27.

Re: Self-ejecting chuck keys Y/N

One key that keeps popping out would be bad enough, but dealing with two of those when using my four jaw would drive me crazy.

Re: Indicating Carriage travel

I have my 2 inch DI to the left of the carriage mounted on a carriage stop type clamp. The length of the 2"DI is such that the dial ends up shielded from the chips by the headstock. I only hook it up when I need it but the dial stays clean. I don't like anything to the right of the carriage because ...

Re: Thread ending positon

You can machine the shoulder to size just like headspacing a rifle. See where it ends up, then take small cuts on the shoulder to dial in the drain location.

Re: Costco LED shop lights?

I'm just guessing here, but I believe LEDs use only half the wave form of 60cycle AC so would that tend to have a strobe effect on rotating machinery?

Re: Cut Off Tool Chatter

I part aluminum at 200 to 360 rpm depending on diameter. I feed with my left hand and oil the kerf with my right. I feed almost as fast as I can and use the chip formation to guide me as to feed. A nice healthy chip curling up is what you're after. I never part aluminum for more than 10 seconds with...
