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. I have never built a model from castings and since the gentleman selling this had one completed and running, it looked like something I could accomplish. However after...

Hello all from Snowy Pa, Does anyone have plans for the Upshure Vertical engine to share? I have built a couple horizontal IC's and would like to build a larger scale of the Upshure just for fun. Thanks Jim

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...
