    What's it worth?

    I picked up this Palmgren 8" rotary table at a flea market last year. It has X and Y adjustment and a tilt function. It is in excellent condition except for 2 - 1/8" holes in the surface of the table. It looks to be used very little and all functions are smooth and without any play if that's the...

    Hello All, I was at the Cool Springs Museum Exhibit last month and picked up a Casting Kit of a 1/2 Scale Nanzy model engine.

    In the past I have used points, condenser and coils from automobile applications and although they work well the coils are large and difficult to hide along with the atv battery in a wood box the engine sits on.

    The Atkinson Differential Debacle, maybe

    Kerzel is finally running

    Hi all, I started the Kerzel almost 2 years ago. After machining all the parts and assembling it all, I tried for months to get it running. It would fire with a drill running it but as soon as the drill was removed it would stall. I even wore out one of the crank bushings from trying...
