Hi Zoltan,

I intend to take my drawings and model the entire machine to produce a booklet which I will probably release to the www community. I need a little time to do this as at the moment I am rather busy, patience...

Cheers,
Greg

PS I have started a lathe conversion, new thread coming soon!

H Eloid,

I don't have a video of it but perhaps now over the summer holidays I will get a chance. I have done little more than cut some Depron parkjets (www.parkjets.com) with it since I finished it.

Let me see what I can do.

Regards,

youtake a picture of your tension control and gear box i like your set up
thinking of doing some simular

Hi Joe,

Yes, you are correct. There is a threaded rod which screws into the base of the upright. This carries a nut which 'tightens' the pinion into the rack, it is adjusted up until the pinion runs smoothly across the entire travel and is to prevent the pinion 'climbing' out of the rack on a sudden reversal. Then a spring is tensioned over this which takes up just the last little bit of play, this spring is quite light and so shouldn't cause the pinion to wear out. I might add a third nut which forces the pinion away from the rack to prevent the constant pressure caused by the spring, it would only carry the load on the very lowest parts of the rack. The rack is within about 0.008" over its entire length and so I am not sure about this one.

Cheers,
Greg

Any progress on that booklet. I'd be very interested in building a similar machine.
