The Piston AZ mount
Posted 28 April 2011 - 01:32 PM
Tuesday I've tried the mount with the refractor. The fine tune mechanism work great, except a small vibration on the azimuth. I will put a felt disk under the piston to brake it in position, cause the roler bearings allow moving it too easy.
I'm sure the mount will cary the future classic cassegrain 200 F/15 I will make this summer.

Cause the slips of the altitude clutch and the too big backlash of the fine tune mechanism on the azimuth, I've made some modifications to solve these problems.
Also I put new knobs on the screws and a eccentric lever instead a screw to activate the altitude clutch. To make the movements smoother I put custom lexan washers instead steel ones.
Now the mount work great, like when small refractors was on it, almost like a dobsonian when not used the fine tune mechanisms.

The only piece made on a lathe is the elastic textolit bushing which is the altitude clutch. Other pieces was made using hand tools and the homemade minimill.

I could't wait to bring them again under the dark sky.
