I bought the cheapest Y axis power feed I could find for my milling machine.

I knew I'd seen it done.

I'm mounted on a bench and can't afford to have the drive sitting in the vertical unfortunately. Need the horizontal version. BTB - They aren't all the same. Have a close look at the drive gear on John's unit vs the one I posted the link to. Different gear configuration.
That's how I imagined it David.
I used the Y axis power feed for the first big job today. I am very pleased with how it operates. I was able to achieve a better surface finish than I have in the past when making the same part. A worthwhile addition I think.
I don't see much difference compared to the Align brand one I bought a couple of years ago. I paid more than $400 including shipping for that one but it was for the z axis and needs more power to lift the knee I think.
@John Conroy did you get free shipping on your power feed unit?
Yes free shipping from Richmond BC
Being mounted on a stand why is vertical height a concern?
I’m planning to build a new stand which will be wider than the base and I want to know how much clearance I need between the lead screw and the top op the stand.
Give the video a watch and the reason will be clear

Hmmmm…… I wonder what it would cost to ship your stand to Calgary?
Probably $200+. It probably weighs 50+ lbs.
From the flat bottom of the unit to the center of the shaft is 10 3/8"

Thanks John!
I just watched Lee's video. There are a couple of things I would do differently but he proves it can be done. The instructions don't cover it well but those thin shims he showed are selective and designed to positively control the backlash between the pinion and the brass bevel gear so no matter how tight the nut is on the end of the shaft, the lash will not change. I would have made an extension for the shaft so the micrometer scale and handwheel could be installed as well as a cover to keep chips out of the gears.
I agree, I would have made the extension longer to accommodate the dials. Seems a shame to leave them off.
I also noticed the lack of cover on the gears, looks like a swarf trap in the making. I wonder if a cover could be turned from aluminum?
The micrometer dial acts as the cover on a Bport style. Held on with the plastic nut he discarded and the threads he cut off.
