Not the sharpet bit in the box

[kennyg]

Well I pulled a newbe bone headed buy the other day I wanted to start tooling up my G0758 mill/drill. The first two items on my list were an R8 collet set and clamping set. I was all set to cut a fat hog in the *** using a 20% discount plus a sale price on both items for about a 40% savings from Enco. I placed the order and received the items in a few days. Anxious to try them out I opened inspected took to the shop the next day to try them out. I put a T-nut and stud on and tried to slide it through the slots no go. I knew I  had ordered the right ones the slots were 3/8" so ordered 3/8" stud and the rest that went with it WRONG 3/8" slots but need 5/16" studs and .605" X 3/8" T-nuts. Well not all was lost the collets were fine a far as this idiot newbe knows, on top of it I had taken the packaging to the dump so I don't think that I will try to send them back probably a restocking fee and postage if they would even accept them maybe I can trade them someplace or sell cheap.Soooo this is not the end of the story I remembered a youtube vid I had seen on some 0758 accessories I think the guy is off base somewhat with his assessment especially with the vise and what he intends to use instead. But the point about the clamp set is valid the T-nuts do need to be machined a little a I said before they are .605 x 3/8" and mine measured .59 X 3/8"

9" from spindle to table is not much room. I got a set of stub drills, but not sure if that's going to be much help on that mill.

Hang on to the T-nut set - you may get a rotary table, and that's the usual size for an 8" RT.

Thanks for the tip I actually do see a rotary table in my future. Back to the video, I think the guy reviewing the vise is comparing apples to oranges isn't a milling vise supposed to be large and heavy and when drilling with it you would use
a collet for the bit doing more precise drilling and for other non-precise jobs us a drill press vice and chuck?

If you remove the swivel base on the vise it will give you at least another 1 1/2" on Z. I see you did already. BTW, I fully agree the vice is too big for the mill. Shars has a 3" vice that may be smaller than the one from Griz and would probably be more appropriate. http://www.shars.com/products/toolholdin...chine-vise

Rather than running a drill bit in a collet for precision making sure you either center drill or spot drill first is much more important. 

If you'll be drilling & reaming and location is critical:

1) Pay attention to your backlash.

2)  Using a properly sharpened drill bit is critical.  The chips should be virtually identical from each cutting edge.

3)  CD, drill & ream the hole before moving to the next location.

4) An Albrecht drill chuck has the least run-out of any brand I know of.

9" is not alot of room but you could quiet easily make a jig plate and use angle plates to attach your work to... you don't have to use a vise.

Take a look at a set up i did this weekend, Notice i used parallels, an angle plate and a fixture plate I had to mill a radius in two directions and a vise just would not work for me. the base fixture jig plate has rows of 10-32 holes in it so its flexible for fixtures, its completely square so i make the set up on the bench transfer the fixture to the mill table line it up with the slots on the table then clamp it to the table.

I really don't use my vises a lot, i use this set up more.... you will get alot of use from simple tooling like this.

Just an alternative  hope this helps...

Happy machining..
