    practice materials

    If you're looking for practice material, nothing beats a local scrap yard. If you have any. I go to a couple of them here locally. One is better for aluminum and brass, the other steel. I can buy scrap aluminum for a buck a pound. Square, flat in various thickness and width, short round stuff...

    Polishing Milled Parts

    First, make sure all of your 240 grit scratches, or whatever the previous grit was, are gone. Very easy to miss some 240 when cutting with 600 but it will really show up when polished. I usually start with 220, go to 600, then 1500. If it's brass, i stop at 600, brass is easy to polish. Then...

    Help buying a lathe

    Well, i'll throw in my $.02 here. The 6x18, what make is it and will it cut threads?? Southbend made a good machine. One made in 1935 is more than likely badly worn, possibly abused. It probably needs headstock bushings, wicks, wipers etc and will need a complete tear down and adjustment and...

    Some questions about a Taig mill

    Thanks for the info fellas!!! Just what i was wondering. One other question. Is the tooling plate strong enough to mount a vise on?? Dean, your website is awesome! I spent a couple of hours there yesterday, and am going to borrow (ok, steal) a couple of your drawings. Have another question...

    Some questions about a Taig mill

    HI guys. I'm in the market for a small milling machine. Have been looking at the SX2, X2, and Taig. Sherline looks a little too small. By the time you get an X2 set up and a belt drive on it, you can get an SX2 that already has a belt drive and a larger motor. I checked out a few sites about...

    Another E-Z engine build from a new guy

    The plans are in the downloads section under E-Z engine for newbies? It's meant to be a simple first time build and was designed by forum members. Many thanks to the guys that put it together. Was a fun little project and definately a learning experience. Regards, j.d.

    Another E-Z engine build from a new guy

    Got it done. Plugged it into an air hose and it even ran! Have a minor problem though. The screw that holds the rod to the piston keeps coming loose. On the other ones i drilled the holes in the rods a little large and made some inserts so i could tighten up the rod screws. On the piston, i...

    Another E-Z engine build from a new guy

    Finally made a little progress. I was facing off the flywheel and my lathe decided it was time to eat a couple of bearings. That was fun, but all better now. Flywheel, axle, and crank are done. Did the flats and drilled and tapped the valve and piston. Only things left are the rods and the air...

    Minor diameter

    Marv, that's a much simpler formula than i have. The one i have is 1/tpi*.61343 *2 and then subtracted from the major. I like yours better. Regards, j.d.

    Minor diameter

    Thanks guys, was pretty close ;D Ken, it's supposed to be 1.240. At least that's what the specs are for a 5c collet outside thread. Thanks again, j.d.

    Another E-Z engine build from a new guy

    Thanks for the tip Nick!. Got the piston and the valve cut, so hardest part is done. Whew. On the valve, i took 2 cuts with the parting tool to set the depth so i only had to cut one direction then after both sections were cut put the parting tool back in and just skimmed the surface to clean it...

    Another E-Z engine build from a new guy

    Thanks fellas. Did feel fairly stupid, but learned something so all is not lost. Did the piston today, fits good. Next is the valve. Not looking forward to that, that piece is small. Will post some pix when i get it made. Regards, j.d.
