Re: Release agent question

Hmmm.

Keeping in mind I have no experience with what I'll propose, is it possible that you could use silicone spray in the mold before ramming the sand? Seems that would discourage the resulting core from sticking.

Re: Building the 2.5" Scale Shay

Thanks. Seems you are plagued by the same issues most of us face who like coal. The world is changing, with changes making some things a lot more difficult for us.

I have fond memories of coal being readily available when I was a young lad. Cheap, too. $50/ton.

Re: Building the 2.5" Scale Shay

On other thing Im considering is how to increase fuel efficiency, since a 2 mile round trip on my home club track takes a little over 1/2 a milk crate full of wood, which adds up over the course of a weekend. Im wondering if a firebox arch would help, or if I just need to give up on wood as a reaso...

Re: Cutting plastic

This device was machined that way. Blowpipe2.JPG It was made from black Delrin and natural ABS. H You never told us you played the bagpipes. That's because I don't. Not that I didn't try. I own a beautiful set (silver and ivory), but my musical talent extends only to playing the stereo, which I do ...

Re: Cutting plastic

I hate turning plastic. I spent almost as much time untangling swarf as I did turning the parts. If you fasten the tool properly and use the required speed and feed, the chips often come off in a long string, shooting above and beyond where you stand. When I face that issue, I put a garbage can whe...

Re: 8hp vs 16 hp

A trauma nurse I dated years ago used to refer to a motorcycle as the quickest way to the emergency room—as a patient. :shock: Worked for me. As a young lad, one with no bike experience aside from having a Doodlebug as a kid, my '63 TR-6, purchased new, landed me in the hospital with a concussion a...

Re: Cutting plastic

I made a circular insert for my vertical band saw, using the lathe. I used plexiglass. It looked beautiful when I was done. I believe I superglued it to the end of a something held in the chuck. If you use glue, you don't have to drill a hole in the plastic. Much simpler to just press the piece wit...

I think I see something new. Is that new?
So far as I know, **that** has been around since the beginning of the English language as we know it here in the US. So, my opinion is -----that is not new. :D

Re: 8hp vs 16 hp

Not to be too pedantic, but the correct term for those two oily things with the fins that make noise and horsepower is "engine," not "motor." :D In mechanical engineering, a machine that converts the chemical energy of fuel into kinetic energy is called an engine or prime mover. A machine that conv...

Re: PB Blaster is Snake Oil

I have never really had luck with any so called penetrating oils when removing rusted hardware. The best luck I have ever had was heat and once broken loose any kind of thin oil that will help with lubrication when turning the hardware. My opinion? You've come down with mental health. It's absurd t...

Re: Rebuilding the Birch 3/4" NYC Pacific

Chris,
I don't mean to walk on a post intended for Anthony, and I'm sure he'll chime in when he has the opportunity, but the tool you see in those pictures is an edge finder. Likely with a ½" body and a .200" diameter sensing end.
