Yet another job that needs milling :doh:
I have almost done the head saddle but I need to mill out a recess to fit the rack that will let me use it as a drill.
The rack and pinion are from a drilling machine that went kaput at work and this is part of the bits I salvaged from it. Sometime pays to be a hoarder especially when you can hoard stuff at work :lol:
I am going to have to think very carefully about my next steps because I would like a 3 speed milling head which will require sourcing or making 6 gears and if I am going to make them I will probably make a temporary head so I can use it to make them.

That lapping plate video from Tom Lipton you mentioned in another thread had him using a carbide tipped circular saw blade on cast iron. I admit I was cringing a bit, but if that's all you have then have at 'er.
I recall one of my first "milling" projects, which was to "mill" out a slot in aluminum using a Dremel tool, cylindrical burr, and router base. Very slow, but it did work. I bet if you stuck a 1/8" carbide end mill into a rotary tool and took small depth cuts using a straight edge on either side as a guide you'd have it done pretty quickly.

I dont need to resort to that sparky I can manage on my lathe it just seems ironic how many milling operations I am having to do with my lathe to make the mill and I havent even started the knee yet.
rather than new post I will put what little I have been able to do today on this one. Been making the wife some shelving for her greenhouse or STAGING as the know-it-all-father-in-law once told me its called but anyway I was going to use m3 bolts to fix the rack in but then thought why bother just make it fit in tight and it cant move anywhere so thats what I did.
Tomorrows task is to make a hole in the saddle to let the pinion mate with the rack in the right place.
