Hi everyone

I am rebuilding a 6 inch f5. The OTA is complete and a picture is attached.

The tube currently fits another mount I have so I have been trying to get it to balance so I can work out dimensions for the rocker box. At the moment the tube will only balance around 20 to 40 degrees. When let go from horizontal the tube moves to 20 degrees, when let go from vertical it drops to around 40.

I should note the altitude bearings are not centred across the width of the tube. They sit about an inch above the centre point. I did this because the crescent shaped bearings didn't have enough wood to attach to if the bearings are perfectly centred.

The focuser is a a standard GSO 2 inch focuser. I do have heavy eyepieces ES 100 degree.

Can anyone suggest a counterweight strategy that might work here?

Should I make new larger alt bearings and centre them properly?

Thanks

Rod
