Retrofitting a 1986 Maho MH400E

That shouldn't be a show stopper. Speeders are just planetary gearboxes, so all of them are going to require a feature like that to prevent rotation of the main body.

Think Mark is correct about end of the taper question. Can the end be removed and replaced with a pull stud ? My tired eyes thinks it may be integral an thus intended for a threaded drawbar use..

Hope this may help and not just add more confusion.

Thanks Bob, I've read a lot of old threads over on PM on the subject today. One guy said he simply cut off the cylinder at end of the taper and then screwed in a retention knob in it's place (there's a matching internal thread in the toolholder).

There's going to be a feature on all speeders, true, but I think some models don't have it protruding upwards (Henninger brand I think has it going sideways). If I have to both modify the toolholder and then it will only work with an extended quill then I don't think it's cheap enough Maybe it's worth waiting a while and ordering a new one that's made to fit my application to begin with. Dunno, just really wanted this to be a great match for my plans, but the Maho is already very much a project in my case and I need to balance it out with the business side and life in general

I think that DIN 2080 pull stud is just screwed in.



One of the tools I bought also came like that. No cutting required, just unscrew DIN 2080 and install the correct stud.

If you look at it closely, it looks like that anti rotation feature is only bolted to the side of the main housing. You could probably remove it and make a new one which fit the MAHO better.

This is probably a really stupid question, but I was wondering about that pull stud, how do you go about screwing and unscrewing it? It looks like it's round and doesn't have any design features where you could fit a key or wrench, unlike the OTT pull studs for the Maho spindle. Is it that it doesn't need to be tightly fastened?

You might succeed in selling me on this idea after all
