Help needed with EQ1

[JonF]

Hi all, I need a spot of assistance. I've aquired a Skywatcher refractor on an EQ1 mount, and it has a bit missing. It's the sleeved bolt that goes though the altitude pivot on the opposite side to the altitude lock knob. As it's missing it's pretty wobbly. Anyone know where I can get a replacement? I've tried AstroBoot, but nothing there. I'd just go to an engineering factors but it looks like a pretty odd bolt - it's pretty big but with a fine thread. To be honest I don't know whether it's metric, imperial or Whitworth. Anyone know? Any help much appreciated.

Can you post a picture?

Can you post a picture?

Of the bolt that I don't have?

[themos]

Yes!

It would help us identify which one it is you don't have!

If I had to guess... it's the clutch lock (such as they are on the EQ1...) but I agree with Themos, a piccie of the mount and the location of the missing bolt would make things much easier.

Measured accurately using a micrometer. It is indeed an odd size, 10.72mm, or 27/64 in imperial. Amazingly, though, I found a bolt to fit in my box of brackets, bolts, nuts and stuff (every man should have one of these). I found an old signal attenuator which has the correct threading on it. Perfect.

Thanks are due to Wrinkly for his offer of the loan of a complete EQ1. Cheers Bill.
