Re: Lathe DRO recommendation
The magnetic scales sold by DRO Pros seam to use a magnetic tape with an adhesive back that you bond to an aluminum extrusion. Aluminum has a high coefficient of thermal expansion, about 3 to 4 times glass depending on the material. On a 12 inch scale with a 10 deg f change, the length of the magnet...

Re: Threading to a shoulder
The Hardinge HVL has a travel stop on the carriage for threading. You leave the 1/2 nuts locked. When it hits the stop the carriage stops and the cutter makes its own relief groove. A quick retract on the compound moves the tool back, you flip a leaver to reverse the carriage which stops on a back s...

Re: MACHINE SWITCH
The VFD I just installed on my drill press has parameters that allow auto restart or remain off if input power is lost. You can even set the power interruption time down to milliseconds. The inputs for momentary on/off buttons work fine as they would on any magnetic starter.

Re: Aluminum Wheel Corrosion
Dish soap probably isn't the best but does work. Was polishing an aluminum canoe this fall, with aluminum polish and a sheep skin buffing pad on the 7 inch sander/polisher. You could see it was shinny through the black residue but when I tried to wash the residue off with windex the shine wasn't the...

Re: Logan / Powermatic 2557
I had a Logan shaper with the reeves drive. If this is the same arrangement Russ is correct, their noisy. I rebushed mine and it was a little better but still noisy,

Re: OT: Building in isolated location
Not sure covering the logs is a good idea or not. Might promote fungus. I never cover them here. The oak should last a long time, pine can get beetles fairly quick. If its going to be a long time before sawing paint the ends with anything to slow the drying and prevent checking.

Re: bushing clearance
Bill not doubting the standards, but at .002 and .003 inch clearance will the bushings take grease? I've had trouble in that range.

Re: New Digital Caliper Ordered
Fractions are neat, BUT. I use a digital height gauge to set the blade height on my table saw. It does fractions but when your looking for 3/8 and its reading 83/128ths which way do you go, up or down.

Re: Clue me in on Spanner Wrenches
I cut them out on the plasma table as required. Think this is the style your looking for.

Re: Wood Pellets as a Fuel Source
The pellet stoves I've seen use forced draft from below the grate. They actually burn with a blue flame and produce no visible smoke. The do produce sparks but the heat exchanger path is long enough to allow them lime to burn up and produce ash in the tubes. In my opinion, and most people that own t...

Re: Any way to calculate the center point of this bend?
Im guessing , as has been said the stock is slipping. I recently built a tubing bender, and incorporated a clamp to hold the tube at the start of the bend. Every bend formed exactly where i wanted it, if I measured correctly. Without the clamp I know they wouldn't have.

Re: Calculate required power (torque)
I looks like you've entered your cutter diameter as 18 inches, so its showing 56,592 surface feet per minute at the tip, and its suggesting a speed of 63 rpm to get 300 sf/m
