Milling machine power feed

[Ben17484]

Your handwheel engages a 3-lobed hub on the shaft; it's part of the mill. Where are all the guts that you took off the mill to expose the bare shaft as pictured?

This is what I had seen in a couple of other videos. My mill isn’t like that though. My handwheel simply pushed over a key on the leadscrew. I’ll take some picrures later.

So this is how my hand wheel is attached:

I think I need to make an adaptor/coupler for this to work with the power feed.

Looks that way. Do you have the model / p/n of the unit and a picture of the illustrated parts breakdown?

It looks like you got the wrong version from Warco, this one is for a keyed shaft https://www.warco.co.uk/power-feeds/303231-wm18-milling-machine-power-feed.html

The instructions for the PM25V unit might give you some ideas https://www.precisionmatthews.com/w.../PM-25-Table-power-feed-install-V1-2-9-21.pdf as Warco are useless in the instructions department...

Otherwise try ArcEuro (red version of the LMS one linked previously) https://www.arceurotrade.co.uk/Cata...ssories/Powerfeed-for-SIEG-X27-and-SX27-Mills

Thanks for this, it’s really helpful. I didn’t actually order this from Warco, I ordered it from a random eBay seller from China. It turned up with a sticker from Warco on the box.

I’ve bought quite a bit from Warco and their spares department is pretty good. I think I’ll ring them tomorrow and see if they can send out the gear/coupler for this version. If not, I’ll make one. Could be interesting.

Warco don’t sell the items I need separately, so I’m going to need to make them. I have a dividing head, so in theory I could make the shaft with attached gear, but how do I know the module of the gear? (If that’s even the correct term). I.e how do I know what gear cutter I need to buy?

Could you make a long bushing to fit thru the gear and modified handwheel, reusing the supplied gear? Loctite would bond the gear to the bushing.

That’s the current plan. I backed out on making a gear and going the keyed bushing approach. I started this morning. Pictures to follow.

I’ve posted this on another thread already, but should keep this thread up to date as well:

I’ve made the coupling to mate the gear to the keyed leadscrew. I now need to make a new end plate for the table and then should be able to fit the power feed.

Finally done! The coupler took me 4 try’s and the plate two try’s! But it’s done:
