Hi gang!
Ok, has anybody used or have an opinion of the very nice looking rotary tables that RDG are offering? I was thinking I might get a 4" to convert to a 4th axis and they seem very affordable, dangerously so. I was going to construct my own belt driven axis but this might be a better and cheaper solution if they are any good.

Hey Smiler,
I was thinking about getting a fourth axis as well. I asked Keith (Kip) about what he recommended. I was also looking for a 4" table... anything bigger won't fit under my gantry.
He recommended the RDG table you posted a link to, and he also said something about knowing someone / having the appropriate stuff to do the stepper motor conversion for not very much.
Unfortunetly, because the stepper motor mounts on the top of the table it won't fit under my gantry, so I'm going for this one I think.
Cheers for that. Looks a nice table and made by Vertex too. I'll drop Mr Kip another line and enquire about the mechanicals to convert it.
:beer:

Thinking of treating myself for Xmas :)
Forgot to mention I got one from Arc EuroTrade
http://www.arceurotrade.co.uk/Catalo...ng-Accessories About half way down... The 4" with the stepper pre attached.
I think Kip thinks it was expensive for what it was, but at least I get to use it straight out of the box without having to design / make / wait on parts to get a stepper on it. Quality seems ok, and it weights a ton and a half.

Dave, thanks but when I said treat i didnt mean quite that much! I think i'll go for the £60 RDG one, I have a spare stepper motor that'll do the job and the mount is relatively easy...Quote:

The backlash adjustment leaves alot to be desired and is difficult set without binding, they are not designed to be motorised so I expect will suffer from high wear in the long run.
Other fact is that they get a bit tall when a chuck is mounted on them.

Haha, your not the first one to express how expensive it was :cry:. Starting to think I got ripped off.Quote:
