Mini and Micro HOSC plans

[stevehuckss396]

I am posting these drawings with Mr. Graham's permission. They are drawings that i generated and used to build the 1/2 and 1/4 scale versions of his HOSC horizontal wobbler. I may have errors like the piston being the same size as the bore so these may not be good enough for the beginner. Please dont show up on my door step with pitch forks and torches. If you find an error, I will gladly correct the drawings and resubmit them to the forum members.

Steve,
I copied the plans into the Downloads and uploads section of the site so they would be easier to find when this thread gets buried with time. Thanks for posting them.

Steve,
The drawings look fine. May have a go at the mini as soon as I get a couple of other projects finished up first. Quick question...is there any spring tension on the cylinder or not? It doesn't appear that there is which works, just leaks a bit more. Actually I made my Elmer's "Tiny" that way so it would run on lower pressure. Thanks for posting the plans.

No spring. There is a 0-80 screw that holds the cylinder on. I found a screw that is a bit to long and then ground it down a bit at a time until it is snug and the cylinder is close to the surface but still free to wobble. Kinda have to feel whats good.

The flywheel is glued to the crankshaft with red locktite. That gets a bit tough getting the wheel glued without getting the crank glued to the bearing or standard.
