Spindle taper on my Richmond milling machine

Feb 19, 2007 7 Replies

Hi,


Some time ago i aquired a small richmond horizontal milling machine. do not know which model but it has a round overarm. Now that i have workshop to fit it in, i have started to restore it. I was hoping on of you knowlegeable people could tell me what type of spindle it ha (or any other information!).



The spindle taper seems to be in between an Int 30 and Int 40 in siz and angle, but does not have the small parallel section on the smalles part of the taper, and the driving dog slots are different (about 1/2") Looking on the internet the closest i can find to it is the ISO35 typ but cannot seem to find a drawing to confirm this. Looking throug other posts i have found that some richmond mills had a morse tape spindle but this is definately not one of them.



Photos of the machine can be found here..

Hi simon The link to the photos can only be accessed if one is a member of your group,and the link to join the group does not work from my computer, maybe that is why there have been no new members,or maybe it is my computer. Also when I do a serch of yahoo groups I cannot find your site, maybe it is me yours in the workshop John

That would explain alot, i just checked and it came up ok for me but

will get the wife to try and join and see. I am also not sure how t make the photo sections available for anyone without joining, but will see if i can, as there is a picture of the correct adapter betwee a 30 and 40 int for comparison

Can't you measure the drive dogs on the spindle? Keyway size isn't that critical as it drives in one direction only, obviously needs to be bigger than the drive dogs.

I have a couple of old chucks on 35 tapers, one a Clarkson and one a Heinz 57, I'll measure the dogs tomorrow.
