If I remember correctly the shaft had a key way in it. To locate the gear.

Hi

Firstly thanks for your reply,

Sadly no keyway whatsoever on mine it was secured in with two grub screws at the end face of the shaft. The issue with this is I would need to drill 2 new holes and tap them to secure it again this way.

I've had a look online on boxford website and they sell the grub screws and the gear has no key way slot in it so I assumed all must be done that way??

Cheers

Don’t remember having to drill any holes. Do the grub screws go through part 17-004? If you haven’t solved it I can be more help next week when I’m back at school.

Morning Neil

No I haven't solved it as yet, the grub screws go through the face of the gear and the shaft it slides onto, so the holes are drilled, then tapped, half of each hole on each part so I suppose it is a kind of keyway, so when the grub screws are screwed in this would then be the keys to stop it from spinning on the shaft, I had a look at the photo you put on a few years ago and it does look like it was the same set up

Cheers

I had this machine a long time ago and had a lot of trouble getting the auto tool post to lock in place.First the shaft should be locked don't mater how or were as long as it is . 2 the rotation is just a number of steps forward and locking is reverse until the steper stalls simple as that , just experiment to find how many degrees to go .3 I had to fit a stronger steper to get it to hold fast and also increased the power . All this eventually worked although the toolpost macro was as usfull as a chocolate teapot ,just set it up as a axis and set it for degrees.The whole thing is very primitive . I now have a M300 that works a great deal better
