    All Doall's are meat cutting saws if you don't watch what you're doing...

    I have (I think) a 1612-3 and it does not have a hydraulic table. It does have the three speed gearbox.

    There are industry standards..NEMA, IEEE, and API come to mind.

    You don't say what size or speed motor...that makes a big difference. But assuming under 600 volts and 500HP, NEMA has standard...

    I have plenty of experience with serpentine belts...and they're not as great as the magazines would have you believe. Biggest issue is they really need a spring loaded 'constant' tensioner unless...

    You're overlooking that the ID of the pulley must be 3" to slide over the pump snout. So an idler bearing would need to be 3" ID and 3" OD given the 4" pulley has a V groove depth of 1/2".

    As above, there is no way to make the smaller pulley an idler due to space constraints. And I do plan to make the R and W the same diameter.

    It would be 'better' if W were smaller as it is only...

    Thanks all.

    Yes, I thought of making W a 6" diameter and that's what I'll probably do. It's not an especially shitty way to do it...at least it's done in a lot of OEM applications that way so for...

    OT- Would this V belt pulley setup work?

    The blue pulleys are all the same 6" diameter.

    The red pulley is 4" diameter, and so is the green pulley. The green is pulley is a smaller 'v' groove on the same pulley as the blue one. In other...

    If you need to spin 30000RPM and are afraid of the 12" chuck being too much, and know you should use the 4" chuck, but don't want to change it out, you can always use the 12" to chuck up the 4"...

    My point is....if you need to spin something more than 700RPM, or so, it's seldom big enough to need to be held in a big chuck. Spin your 4" chuck at 2000 if you must. But even then, most things...
