Peter the grubscrews in mine were 6mm so I just simply replaced with 6mm cap screws. Standard is 4mm I think.
Just weighed all the bits with bathroom scales.
100ED assy 7.0 kg
150mm assy 10.5 kg
300mm assy 6.5 kg
10SN assy 17.0 kg
The 100ED and 150mm achro weigh more as they both have a 2.7" Astro Physics focuser which are quite heavy and very solid.
Finder assy 6.0 kg
Fridge assy 2.0 kg
So 10SN + 100Ed + finder is 30 kg or 68 lbs the Canon would add more and the main bar of the side by side is about 2.0 kg. So the EQ6 is doing quite well to hold and autoguide this little lot.
The 300mm set up is about 21.5 kg or 48 lbs
The 150mm and 100ED etc is 25.5 kg or 57 lbs.
I think I should carefully balance from now on. Although this is relatively straightfoward with this side by side.
