adding a 4th axis?

[turmite]

Airbrush, thanks for the kudos, but most everything I have given you is right here on the zone. That link was here, even though I put it here before. Seems I had lost it from my pc.

Yes I have a 4 axis but it is a little different in that it is a special purpose design just for doing rifle stocks. I designed it and had a frined of mine build it, since I have no metal working tools. Attached is a jpg of my 4th axis holding one of my rifle stocks. The gearbox is to the right and just barely visable, but that is where I made my largest mistake.

edited to add: I know Colin by email and talking with him on Skype. He is a nice fellow and having watched his video that is linked at Rab's site....(I think)
I can tell you he builds a quality product. I'll try to find that link later and post it.

Here is a link showing the 4/5 axis heads in action.

cool...thanks for the vid.

I emailed for more info and pricing on them, just waiting for reply. Hopefully the pricing is within my reach. If it is that could open the door for a whole new bucket of ideas and problems....hmmm can you say 5 axis machine...ha. Would need a fairly large machine to make the 5th usuable though, don't think the rockcliff fixed gantry design would allow for much of a usuable work area with that mounted on the Z.
...more things to think about now..ha.

look at post 19,
told you to look at rainnea graphics using the doughty drive and gave you the price ages ago...

i already got the quote $750 per axis plus about $300 for a link plate if you want the head shown with the 2 rotary axis,
in stock 1 week delivery.

Yup...just received an email from them with the prices you mentioned .
Looks like i'll have to go another route...so far the only other one i've seen is the sherline model. Does anyone know of any others?
