Do you have the 1/2 scale 1 1/2HP kit? Approx. 10" Flywheels? If so I have the same kit, I will check to see if my plans are more complete. I plan on using a spark plug like the 1923 Engine had.

I used this exact one from HF on the little toolpost grinder I made, it fits right into the Aloris style tool bit holder without any modification. I use diamond cutters instead of abrasive wheels that seem to bounce all over the place.

This is a FlyBall gov. I built a few years ago, it shows how the motion is tranfsered.

I use my cordless drill to spin the needle stem against my 1" vertical belt sander. I also use this method to round off the corners of sharp pins & screws that I have cutoff.

A question for Mike N I cut "O"ring grooves & install high temp "O"rings instead of gaskets all over my IC engines. Works Great! ********************************************* I use silicone "O"Rings good to 425F http://www.mcmaster.com/#o-rings/=lt3mdc I use 1/16th thick & make the groove...

Brass does not necessarily make a good bearing surface. Not all Bronze is bearing material either. I'm not quite sure why you need to know if its brass or bronze?? I have a bucket with left over brass & bronze scraps & the color seems to different on most every piece!

Draw a little sketch of the arc you want to machine. It sounds like a rotary table job to me!

McMaster.com has a great selection bearing bronze bushings all ready to go!

Is this a Atlas lathe? The main bearings are bearing bronze, you could make them on your lathe!

Is the small arbor spindle rigid enough? Maybe a larger hub & a dead center would work better. Maybe it works fine if you are milling aluminum.

The answer is 9/32nds:wall:

I would keep it, you can sand off the chrome in your lathe & end up with a nice brass tube when you need it. You should be able to get scraps for melting!

McMaster.com W1 Tool Steel works great for crankshafts. Don't even heat treat it. This stuff is cheap & ground smooth & straight.

You can often find great tools on eBay. I have purchased used American made measuring tools for a fraction of new prices. The quality is far better than the cheap China made stuff!

Good gage blocks are lapped & designed to ring together when twisted. This will allow you to stack up several blocks without any accumulation of thickness. I have a set of the cheap imports & the finish is too rough to ring together. These are certainly good enough for the work I do! Oh! buy...

Is this made to cut metal? Sounds like a wood cutting band saw. Does it have 3 small wheels, if so the metal blades don't like the small bending radius.

Put a milling vise on the table & a drill chuck in the spindle & whats left in the "Z" ?? Is the horizontal spindle drive completely disabled? Around here I see Bridgeports selling for $ 1,500.00 some have DRO's & power feed. Its clean!

Where did you buy the castings from?? Paul Jacobs [[email protected]] Sells the Aluminum castings This is a great set of castings & drawings.
