    Started work on the mill head today. I'm replacing all the tapped bearings and maybe the bearing on the hand wheel, also put the mill head back onto the ram as not to damage the paint work and it was easier this way. It's looking like a milling machine now.

    Been cleaning up the gears for the mill head and replace the bearings. Now have a problem with the spindle and shaft gear, as you can see there is quite a bit of damage to the teeth so off to ronson gears and find out if i can get new gears and then get them machine and i think the teeth may need to be hardened??

    I think you might need to prepare for sticker shock when you get the price to make new ones. The part with the gear on it is repairable. I saw Phil get a spindle nose rebuilt that had been chewed to bits, it was an amazing job that was done. Probably TIG welded I would guess.

    The bottom part does not look too hard to make in the home shop.

    Yeah i know what you mean, my thinking is to see if i can buy these gears and take it to my local machine shop to have the teeth milled out. The part with the gear is on looks like it has bee tig welded on bit hard to see in the photos.

    The top part could be supposed to be soft as it might be a consumable part.

    I suspect most of the problem is from operators changing speeds when the machine is still running and grating that dog clutch.

    Yes will see if i can file it, i think that is how you can tell if it is hardenede? Ah is this what it is called dog clutch, i'm not to good with my temology with milling machine parts but i am learning . The previous owner said he could not run the mill in reverse as it will pop the fuse, but it's making sense now as i turn the top gear in reverse it push the bottom gear out, this is why he mark a x on the control switch. I think he did not won't to make repairs on the mill

    I finish off cleaning and inspecting the mill head parts and have found another problem to fix, as i was removing the shaft from the clock spring housing the second piece broke off so now will need to modified the housing. The clock springs that are available are not for this type of spring housing which uses a pin. A photo here of what i want to do with the housing.
