I have a Super 7 and have recently purchased a dividing head. I plan to use it for milling octagons using the non-swivelling vertical milling slide (probably overkill to use a dividing head, but hey!). I therefore have the milling head axis at right angles to the lathe axis. However, I'm finding that the cross slide needs to be wound out a long way to bring the milling cutter anywhere near the workpiece, held in an ER20 collet in the dividing head, as the vertical milling slide does not fit the T-slot in front of the top-slide hold.
So... my question is, do I need to purchase the (expensive) milling slide raising block, or is there another way?

You probably need a raising block, but easy to make one, could use a lump of aluminium, cast iron, or mild steel.
Also if you are using an ER20 collet then I guess it's in an MT2 collet chuck? That will have quite a long overhang which will contribute to the problem. The Myford DH is best used with MT2 collets that fit the arbor direct, as long as your stock fits a standard collet. Options are either the Myford collets with the threaded closer, which are rarer than hen's dentures these days and anyway expensive; or to buy single finger collets like these and use a bit of studding as a drawbar.
