I'm amazed at how people who have essentially NO understanding of propane fuel systems can muddle through them as they do, and not wind up blowing themselves and others, straight to the moon. The...

There were TWO versions of the Ford 192 industrial. The earlier type is a four-cylinder decendant of the 134/172 lineage.

Unlike the 192 THREE CYLINDER gas, the 192 four is a remarkably weak...

Jancy and other manufacturers DO make a variety of arbors to fit their annular cutters, but you'll probably find that metal-cutting annulars will need more torque than a 170rpm reduction from an...

There are many motors that are built specifically to be upright, and if yours is one of those, I encourage you to mount it vertically, and frankly, vertical mounting can be convenient in terms of...

John... which Monarch are you trying to run?

The 3450 speed rating (it's a 2-pole motor, so it actually sees synchronous speed as 3600, but when fully loaded, it sees max load/slip as 3450, which won't happen on an RPC idler...

but yeah,...

Tony, I've got a dozen comm-racks between my radio room, electronics bench, workshop, and band truck, I gotta carry an assortment box of probably seven different screws just to swap out a unit in any...

Welcome to the forum. It requires 'electric power'. Aside from that, the information you've posted is insufficient to provide any better answer.

Duty cycle suggests how long the machine will...

Any history study will reveal the huge world of covert resistance inventions, and as crude as they may seem, they were incredibly effective, by virtue of the dedication of the individual using it.

I don't have your motor... I have the 1hp 'pancake' motor on my J-head, using stock step-pulleys, but I basically leave it in direct-drive (1:1 position). I have my VFD set to 170rpm, and the...

For a jig borer, that's exactly what I would do... fit a common motor type, and use a VFD. I'd yank the motor's mechanical cooling fan and put a constant-speed fan on it in the process.

The easiest, fastest, and simplest way to accomplish this, is to just add an additional idler or two. Get a couple big 3-phase motors and connect them to the RPC after it's started. Let them spin....

When the CP200's input was Wye, the transformer's 480v coils were running on 277v each.

Breaking the Wye centerpoint, and driving TWO of the three coils directly on 240v delta resulted in slightly...

In my RPC, the external control device, is the dimmer, and it has proven itself more than sufficient to very reliably handle the circumstances of the last 20 years' use. The circumstance of a...

ANY relay is a voltage sensing relay, once you've determined what it's pull-in current requirement is... just add appropriate resistance to it, such that it doesn't reach pull-in strength until your...

This thread is well past expiration date...

I echo sentiments of the others- your internal SPC is basically holy, and the identity of every part produced, wether fail or pass, needs to be indelible, and for at least a half-dozen reasons.

Thanks Mike!!!!

Boy, when it rains, it pours... Die Filers! ;-) I got two, so sent Mike a PM...

The advantage to going higher voltage, is lower power loss and ability to go smaller conductor cross-section, but the disadvantage becomes insulation resistance ratings and code compliance.

As Adam noted, direct CNC machining of plastic is not so common because it is, by nature, wasteful.

CNC machining is HEAVILY used in the manufacture of plastic parts, just not in the 'direct'...

Romak- this is clearly a rotary vane pump. The operating principle is simple- the spinning drum has vanes which slide in and out of slots. The drum sits inside a round housing, but it is offset to...

While my hearing isn't what it used to be, I can still hear to 25khz fine... and I hear my VFDs' primary and overtones pretty well, so I can sympathize with anyone who finds it uncomfortable. In...

It generates a wonderful arc, which in and of itself, is an intense generator of wideband HF noise. Turn on an AM radio, set to the strongest local station, and listen when the plasma fires up. ;-)

Hey now, Jim- that's rapidly approaching out'a line... Just because I don't run a rotary converter often, doesn't exclude ME from being an asshat too... ;-D
