Broken thread?

Form tool with a back rest might work. Maybe a multi edge tool that looks like an inverted countersink would be better. Are you starting off with solid...

And shouting in my best 7 year old's voice: "MOMmmm..........Paulie broke the interrr--nettt !!! ..............

And don't forget the quantity lost out the chip pan. Chips can hold a tremendous amount of liquid in their little cracks and crevasses....

I'm trying to view the thread about a 15HP RPC started by The Metal Butcher today and it appears to be "broken". All I can view are two posts...

Speaking in broad, and general terms here, not carved in stone. A face mill tends to be the tool of choice for heavy stock removal in production environments...

Nice job! Very impressive. What lathe are you using?...

[tom_d]

Ahhhh...so there's the problem. It's just a loose nut.

Where is it?

Behind the controls.... 😉 (you're gonna live a long time...

[tom_d]

Yup, that'll work. What size are the screws? Can you counterbore the tool bit shank so the screw heads are flush? Screws are going to see a side load...

[tom_d]

Nice idea, in theory. Unfortunately the leverage of an interrupted cut against those threads is going to loosen things up in a hurry. If the shortened...

[tom_d]

Laws of physics always apply. A body in motion tends to stay in motion. The larger fly(wheel) cutter's inertia will help smooth out the interrupted cut,...

My 10L has about 20 thou backlash too. It's the newer large dial machine, so that's 20 thou linear, or 40 on the diameter. I've never experienced any...

The opposite of adjustable is rigid. In machining rigid is a desirable quality. Making a fly cutter is a basic, do it yourself home shop project. Even...

While bronze can normally be cut dry it can generate a small amount of heat. If you're concerned about dissipating the heat then a water based coolant...

[tom_d]

All the brass and bronze threading I've done dry. No fluids at all. On a few where the chips were getting in the way I used a spray mist nozzle with air...

[tom_d]

Taper is often referred to in inches per foot, so in your case that would be a .75 inch reduction in diameter for every foot of length. Fortunately for...

I didn't realize Harleybond came in a tube. Thought it was only available in a rattle can..............

[tom_d]

That part looks like a prime candidate for a cnc lathe with live tooling. Come in to that grove area at about a 45* angle with an end mill and rough out...

[tom_d]

This. If the setup allows. A piece of HSS mounted in a fly cutter and away you go. Otherwise, ball end mill tilted if the setup allows. If the spindle...

[tom_d]

Screws or rivets, I'm sure either will work fine. Which ever way you go, when fastening sheet together I've found it's easiest to just jump right in and...
