Scope boom stand question

[ECO-DAVE]

I have a Bausch & Lomb stereo zoom five that I would like to put on a proper boom stand. I have been looking on the Amscope website and they have several boom stands, I would like to know what the difference is between a single arm and a double arm boom stand in relation to engraving. Any suggestions would be greatly appreciated.
Thank you

The double arm booms often have bearings in to aid movement fore and back of the horizontal arm. The standard booms are fine as the scope is not moved in relation to the work. The work is moved in relation to the scope. once it is set up you just leave it where it is. dont forget you will need a cradle for that scope rather than a ring mounting.

I also asked a similar question about a month ago. Search the archives and you'll see some examples of "homemade" stands. Not bad, not good, but gives you food for thought in what is possible.

The double arm keeps the scope from rotating during movement. I believe this is important as you will often want to pus the scope aside to view work or move it an inch or two right to left. Fred

Thanks.... So the single arm cant be swung to the side without it spinning...correct? I have the B&L cradle for the scope so I just need a solid stand.

once you center your scope over the vise center, there should be little need to move the scope toward or away from you. it's best to learn moving the area to be engraved over the vise rotational center. for nearby cutting, if the line to be cut is fairly close to center, you can simply move the scope laterally a tiny bit. using the scope for me was awkward at first. 1 or 2 practice sessions, you'll wonder why you didn't get one sooner. a centering vise is very useful for moving an engraving about a bit without dismounting the piece. the horisontal boom on my rig has a locking screw that prevents inadvertant rotation of the scope. there's a milled slot on the very top to assure the scope is locked into proper orientation. i have some fotos somewhere of a gadjet i made that allows much more shift of the engraved piece. i'll look for the fotos.
jayismonk450@gmail.com yes-- you can swing your scope anywhere you want, just assure you return to the rotational center when you begin engraving.
