Retrofitting a 1986 Maho MH400E

If you can easily get a motor mounted to drive this it may be better solution. Been looking at that option but I have no easy way to mount a separate motor to drive the extra spindle on my milling machine.

It seems all hobby machinist sooner or later develop a perverse attraction for making spindles

Andy, would you mind sharing your scalering.ngc macro please? Do it just do the ticks, or also the numerical markings?

I need scales on a couple of jobs which are already mostly done like my drill press downfeed knob, or the universal tool holder on the Clarkson.

Thanks. I only searched for scalering.

I need to surface this old anvil, but clamped to the table it is not high enough to reach it with the horizontal spindle. Good excuse to have a play with the slotting head. I ground up a cutting tool with quite positive rake to keep the cutting forces low. The stoke on the slotting head needed adjustment to the maximum of 80mm, which limits the stroke rate to 50, so I used 40 rpm / 40 strokes/min here. 0.1 Ap- depth of cut, and 10mm/min feed rate.



Only got the first pass done yesterday, and it looks like there might be hard spots in the surface, so I might have to give up on shaping it. I'll do a couple more passes and see. Sorry about the crappy photo, but I had to reach behind it with the phone.

Guys, I have a question. After ordering the schematics for my machine I also asked the DMG reps about other available documents for my machine. The response I got today was they can sell me the manuals I already have and a spare parts catalogue. Does anybody have a catalogue like that (for any type of machine, not just MAHO) to tell me whether I can expect to find anything useful in it? Presumably, there aren't any drawings and it's just a list of stuff?

I inquired about these documents just in case they might have something I could use during a rebuild (which I'd love to do this year), but that doesn't seem to be the case. I was inspired by this American mill rebuild video in which you can see the guy has a booklet with drawings of all the assemblies that seem to be a fantastic help for repairs:



I'd appreciate any input.
