Hi Phil,
No problem
Looking forward to seeing the fruits of your labor !
It would be fantastic to have a 'one size fits all' bracket but alas this seems to be unachievable due to the range and diversity of different focusers on the market. The closest I could get was making the bracket adjustable in length. Personally, I found fitting the bracket much more straight forward with this length adjustment.
I will be very interested to see how you get on. Never ceases to amaze me how ingenious guys get coupling the motor to their particular setup
Cheers,
Dave
