If I could have only 1 machine it would be the Monarch EE. In good condition the limitation is the operator's skill and never the machine.

The proper reply could span a hundred pages. The one most useful thing you can practice with a lathe is making parts to size. Part of that end is producing a good finish so you can reliably measure the part too, without the measurement varying wildly. Press fits come to mind, where you want to make ...

I like the back of the table for reasons mentioned above. I would caution to add a positive "stop post" which will contact the top of the column dovetail before the scale or reader gets crunched. While I know you all urge caution on yourselves when installing that fine DRO, but a couple of years fro...

I think Flybynight has given excellent advice. Run the motor on 220vac if possible. Bring the Neutral wire for 110vac for the controls. Bring the Ground wire for safety. I had a Craftsman tablesaw once...nice machine with a USA motor that I eventually traded for a Powermatic 66. I digress, but I ori...

I've installed Newall DROs on a Bridgeport and Monarch 10EE recently. The Newall has a nice forgiving mounting system. However, I found a good transfer punch is very good for getting things where you want them. In the case of the Newall one ends up mounting studs (they call them "pillars") with a th...

Replies: 11

I suggested this to somebody else who was considering gib replacement. I'd rip a strip of hardwood that you can stick in there and whittle away at easily to determine the proper dimension at both ends. A little Kentucky windage and interpolate the dimensions between the two ends to get the taper. Th...

For as thin as that channel looks (is is 1/8" thick??), I think you could get away with an ironworker's punch attached to a heavy mechanical arbor press. For example, A #4 Dake or Atlas is rated at 12 tons of load. Check Machinery's Handbook for the load needed to punch metal, it has to do with the ...

Richard, one solution to the problem is a VFD, it basically allows speed changes with the twist of a dial. I'd recommend keeping the mechanical speeds available & working because there will be times when you need the HP at a lower RPM and the VFD will only deliver motor HP within a certain frequency...

You know, Jerry, now that you bring up pipe, that spurred an idea...what about making a "truss" of sorts, say 2 long pieces of pipe, say 8" apart. Connect these with a variety of perpendicular "rungs" as well as some diagonal braces in the "rung space". I think you could make a stiff beam like this....

I would use nothing less than a C6 and probably a C8 for the long spans. The deflection spec is fine & the calculations meet it but I think you'll find it makes a flimsy workbench. Consider that there is a distinct difference between designing for stiffness and designing for strength. Classic exampl...
