Hi Jeremy,

Is it the wee little screw that fits into the knob that you are after?

If it is, these would be called grub screws. By the look of things, the ones for the knob very likely will be M3 in size. If you have an M3 screw, try it to see if it will wind in. If it's the right size, it narrows your search.

Found this assortment of grub screws on Ebay UK:

If it's the complete knobs you are after, have you asked Astro Boot? If you are able to measure the size of the spure the knobs fit over they should be able to help.

Perhaps it was my explanation but you are right it is the KNOB I need thanks

Tried astroboot, nothing :(

Have you asked the UK distributor of Skywatcher products? They do carry spare parts as they also repair items.

[Ukastronomer]

Yes, OVL, I am awaiting a reply, but they don't carry spares so if they can get parts it will be a two month wait from China

Something else you might try Jeremy is a local electronics store (here in AUS it would be Jaycar). They often stock different knobs used for amplifiers, radio's etc; you may find something similar to what you are looking for... worth checking out...

For the purpose at hand (as per the Youtube clip) the knob seems a bit improvised. Could you not do it properly and use a timing pulley with matching belt? Those come in all shapes and sizes, including with set screw. The pulleys often have rims, so the belt won't slip off at the most inopportune moment.

[Ukastronomer]

Thanks but NO thanks it is that one second removal I want to revert it back to manual focus and then back again, but thank you for taking the time to reply

[Ukastronomer]

What a fool, I never though of that and for something else I need, many thanks

[Ukastronomer]

Thanks Outcast, I think I have just become the worlds leading expert on BLASTED machinery clamping knurled knobs

Never google that

:)

I have ordered one of these, I give up trying to find a knob

[speach]

THANK YOU I have just ordered a supply of the grub screws as I am making the knobs, so this info was most important
