New Z axis

[yukonho]

I have finally had the time to get this all together. Took a while to get the bearings, then of course machining and getting everything to fit perfectly.
It is designed to fit the RotoZip by Bosch, mounts very firmly with one bolt. Any NEMA 23 stepper bolts to the top and drives the 3/8-12 ACME precision leadscrew going through an acetal leadnut. Bolts holding the bearings on the left side are threaded right into the backplate, and the ones on the right are adjustable with a set-screw, keeps the bearings snug against the 1/2" steel rod.
This will bolt to the Y axis with the four 5/16" bolts.
I have a few of these under construction, and I will list this one on eBay.
(just added some better pictures)

Thank you very much. The price is low but is too much for me. I can not afford.

Thank you again.

Really Really Sweet!!!!!!!!!

Thanks Phil.
I am making a different version of the back plate so that I can mount the Z axis directly to another set of V groove bearings that will run on a horizontal set of rails for my X axis.
That is a couple weeks away though.

I know you have said in your add that the router and stepper is not included but
I think you will have less complaints if it is in super big red letters.

Thanks Greolt for the heads up. I have changed the listing as you suggested. Have a look, if you will, and let me know if you have any more suggestions. I am fairly new to ebay and VERY new at HTML. I welcome suggestions to improve my listings.
Thanks for the kudos Jason. It is a fairly time consuming process to develop something like this, I am glad it turned out as well as it has.

Nice looking design. I was just looking at your ebay listing but I didn't see any dimensions or length of travel. It might help to have that in your description.

Thanks juzwuz, changes made!
