Removing the Hercus O Mill Standard Arbor
Have had this mill sitting for about a year now and am starting to look now into getting it going.
Before I start looking at the motor conversion or replacement I was hoping to see that everything is in good order before I spend any money. When trying to see if the vertical head fits and it has all of the required bits I got stauck on the arbor.
I can see from some of the documentation that I have that the standard arbor has a No.3 morse taper, a collar sort of thing then the parts that you can see. The cutter and the various spacers held on by a nut.
I have tried backing off the nut at the motor end a few turns then hitting it with a piece of timber and a hammer. This sounds very solid so I havent wanted to go too hard.
Does the collar have any fixings in it to keep it from coming loose? Or do I need to give it a good whack? There is an allen key but it looks like it belongs to the spindle nose rather than the arbor.
Is there a trick to locking the arbor in place to undo the lock nut? Tried placing some timber on the bed and raising the bed to stop the cutter from turning but didnt work. The timber just rotated and pushed the timebr out.
Lastly, any good tips on removing the surface rust? Both the lathe and mill have more than their fair share. I ruined the paint of the lathe by using degreaser so I am a little shy about just jumping in.
See attached PDF for a illustration of what I am talking about if needed.
Would very much appreciate any advice given. Thanks!!
