Re: 24" American #1 Planer restoration - torque spec advice

I don't think safety wiring is a substitute for adequately torqued fasteners. If the bolts are left loose the normal vibration of the machine is likely to cause some wearing of the parts. Use shims between the parts as needed.

Re: Running copper, installing new outlets

The designations L1 and L2 are completely arbitrary. Once one of the lines from the power company is designated as L1 it is generally kept that way throughout the facility. There is no way your welder can distinguish L1 from L2, unless it can read! :-). The red stripe is just to distinguish that lin...

Re: Cutting Splines

It may be possible to use an existing spline shaft and splice it to your shaft.

Re: Atlas 618 lead screw won't spin when banjo is tightened.

I think Spro has it right. A banjo pivot clamp is not intended to prevent the banjo from rotating on the pivot. You are apparently missing the banjo securing bolt. It fits thru the long curved banjo slot and screws into the plate behind the banjo.

Re: Need help with threading

There are formulas but what is easiest is a "tap drill chart" giving recommended drills for standard taps. The recommendations will vary somewhat depending on type of material, percentage of thread desired, and whether number and letter drills are to be considered. Just do an internet search for "ta...

Re: Best way to thread without gears?

A 5.22" diameter gear with 92 teeth is definitely 18DP. Although 18DP gears are not carried by some companies, that is the size for gears on the common 9" South Bend lathes. If you will get a copy of the South Bend "How to Run a Lathe" it will give you the gear setups you need to cut any thread you ...

Re: improvised boring bar

My first job on my AA Products lathe was boring some aluminum castings to make blocks for fork tube straightening. I bolted the blocks to the face plate and used a drill bit clamped in the little lantern tool post for a boring bar. It was crude but got the job done.

Re: Drum switch broke

The control transformer with the green label is connected for 220 volts so the motor should also be connected for 220 volts.

Re: Do HVLP Paint Guns Clog Between Coats?

I don't know the details but I do know that some of the modern paints are so toxic that respirators are not adequate protection and a forced air mask/hood is required. I would be concerned if I smelled the vapors from those types of paint.

Re: Proper Phase Clock

Vector diagrams are only an aid to help visualize how AC circuits work. It helps to keep in mind that voltages are not "at phase A" for example, but from "phase A to phase B" or "from phase A to neutral". In other words the voltage at any one point can vary depending on where the other point is. Pha...

Re: Another VFD question

I have no experience to back it up, but I suspect a VFD running a 1/2 HP motor would be unlikely to care if a 1/20 HP motor was to be added to its load any more than it would care if the load from the 1/2 HP motor were to increase because of a heavier cut. I also suspect the minimum load from the 1/...

Re: Proper Phase Clock

This is a common somewhat difficult to understand concept. If I could draw a diagram it would be easier. The whole problem is that you have to keep your vector origins in mind. Draw two equal phases at 180 degrees, as the single phase 120/240 is AS REFERENCED TO THE NEUTRAL, then you get a straight ...
