Your scope must have a shorter range in its field of vision Gordon. I’ve had mine out as much as 110mm to be able to see the entire facet on a stone only 20mm in diameter and I think that is getting close to the limit of its outer focal range.

It’s a pain having to un-index a lot during the polishing stage with the setup like mine. But it does have some advantages.
Such as its rigid and the scope once set stays in focus, also repeatable. That is once I have the setting for a particular row of facets, I can return to that mast height boom angle etc. in seconds.
Going to make the mast and boom out of T track, the same as the fine adjustments on my current setup. This is the first time I’ve used it and I like it, its light, rigid, slides freely and locks solid in position.

Hi Frank,

It might have,  there is a fair range of adjustment and mine is only a cheapie.



I repurposed the brass fitting from my old, no longer used gas lantern extension into a bracket for the scope.  It works really well, now I have height adjustment and don’t need to fiddle with bits of string.  The added benefit is I have somewhere to hang my splash guard when it is not in use.

I am still playing with lighting, but used the scope for the pavillion of the morganite I finished last night for my daughter’s birthday. 

Using the scope has sped up my faceting no end
Yours Sincerely
Flash (Gordon)

Looking good Gordon, not possible for me to make a scope stand along those lines.
Have most of the parts I need for my scope stand and have made the part where the vertical and horizontal T bars slide through. Have redesigned it so at that point it does not swivel and now swivels next to the scope support.

Hi Frank, fitting it to the mast base is the way to go.  It’ll move with the mast.

I think from memory your mast doesn’t swivel.  If it did you might be able to fit the scope bracket to the mast to be able to inspect the facet while swivelling the head through the light beam. 

I’m cutting some red Zircon and by swivelling the head while inspecting the facet can see the scratches light up.  An absence of reflections = no scratches.
Yours Sincerely
Flash (Gordon)

Yes, your right Gordon my mast does not swivel. I built the machine around the Ultrtec design and it’s not possible to fit the scope setup to the quill support.

These are the T bar components I will use to replace the wooden contraption I’m currently using. The bridge is made from 25 square ally milled in the centre, the three holes have nothing to do with it, I made it from an old faceting head mast. It will slide up and down the vertical rail and the horizontal rail slide through it.
The handles are threaded 8mm and I will lock cap screws into them, they and other types of locking mechanisms are all made for T bar slides.  All these parts are from eBay, either Sydney or Melbourne stock, what you see here cost me $93 including postage.

Got the new stand finished and tried it out at different angles to see how it was working, have not cut the rails to length yet till I’m confident I don’t stuff it up.
The purpose of the stand is to maintain the scope at a precise position.
