Yes it is a "V" belt drive, which will soon be retrofitted with a 10 Craftsman horizontal drive unit.? It seems to work quite nicely, although it does have one draw back, which will I will?remedy soon.?

?

?Unfortunately, SB did not give much thought into this type of drive unit, mine is of the older style, no bushings/bearings, etc, and was worn when I got it, is wearing out, and finally have decided to do something about it.? So, have looked at several designs from logan, atlas, craftsman, and was going to make my own, but recently?was able to pick up a complete craftsman?drive unit off ebay.? There drive units, are, or seem to have a much more functional design approach to them.? Will soon find out.?

?

?Anyone that is reading this, and has the same "V" belt drive unit (SB), I could use the diameters of the three pulleys, I'm sure the ones on the craftsman unit are not of the appropriate size, it would save me a?lot of time in figuring it out, mathematically based on the mtr pulley and the pulleys on the headstock spindle and spindle speeds.

The lever operated turret was a stroke of luck, fished it out of a scrap metal barrel, and the guy said "yeah, I'm tired of stubbing my toes on that @#$ thing, etc, etc," it cleaned up real nice and it is still in the tooling up phase (always something to come along and divert one's attention).?

The bed length is 4', the original was 4-1/2', but was worn out, and picked up the 4' years ago.

?

As for the 5c collet chuck, this is a real nice project and considering the commercial ones at $250 plus, I figured why not.? In the article, there are some very close tolerances to maintain, but patience will be rewarded with accuracy.

?

Oh, the little tool block on the compound, homemade aloris piston type, it was fun to make.? Sure beats the old rocker, but did not throw the old holders away, now and again there's a need.? Someday will up grade to one of the less expensive wedge type, someday.

?

Have a great day.
