hercus c extended cross slide
g'day eveyone. Ive had this casting kicking around for years. I nearly tripped over it a few times.
I started the cross slide upgrade years ago. At my old work I roughed out the top surface sides and tee slots.
and turned it over started doing the lower part.
I lost the dimensions years ago.
I didnt think enough about it. as usual.
I had to set it up the so the First side i machined was square to the table. Not square i think i mean straight on long the table.
Plus i had to check and square up the vertical head. I did this with the aid of a DTI indicator mounted in a collet in the vertical milling head judging around a large roller bearing.
please excuse my photos . good ones are beyond me at the moment.

I suppose i was just playing around. with the set up because i dont have a great deal of suitable clamps for the job.
The Problem im having is.I think i need to make a set up that i can do more than 1 cutting operation. As it is now.
I think i should be able to get the casting to overall dimensions and square ect . Cut the dove tail. plus drill and bore the ho;e in the middle that the lead screw nut mounts in.
but My milling vises are to small to hold the casting. I have a larger vise. its more of a drill press type vise. what do you think?

How should i set this up. Maybe i have to make some clamps out of maybe big key steel or other flat bar i have.
Has any one got any ides on work holding ? does any one know the dimensions of it. I think im doing it in the right order.
