In 2017 I bought my tablesaw from Woodford Tooling in Stockport, I forget the name of the manufacturer now, they are basically a Delta Unisaw, the same ones sold by Powermatic with a different coat of paint. 3hp, superb saw, bit much for a home workshop really. £1640 including pallet delivery...

Table saws are as old as the hills. I’m pretty sure, like you say, if the manufacturers thought several hundred extra RPM at the tip was going to make such a difference, they’d just increase the size of the arbor pulley, which wouldn’t be by much, and bingo, you’d have your extra speed with no...

I suppose to an extent, if you run a tablesaw with a 2” diameter smaller blade, then up the arbor speed effectively to compensate, you might as well just run a 12” blade. It’s the circumferential speed we’re talking about. You shouldn’t harm the motor, nor the VFD. Changing the frequency is...

Don’t have to keep it to yourself, overrunning motors is OK as long as it’s within the spec of the motor and you’re not putting undue load on it. Mainly it’s bearings you’ve got to be careful with, and whether the saw itself is OK to use at that speed.

I presume you’re talking about an RS or something similar. They were 6 pole 900rpm motors originally and a very big lump of a thing. Hopefully changing the mount on the saw won’t be too bad, it won’t have had a motor like yours to begin with. I can’t remember exactly what mine was like...

Correct. Most table saw motors are 2 pole, or c.2800rpm. If the data badge shows 1350-1400rpm that is 4 pole. Most planer motors are also 2 pole, certainly the older ones (Wadkin etc..) That is the cause of the inrush current. Press the green button and the saw instantly tries to run at...

The OP has obtained a 2HP motor, so on the proviso it’s metric, that’s a 90L frame size with a 24mm shaft. There’s no exact correlation with 24mm to imperial so it’ll either be new pulley or himself doing a bit of machining, and I suspect a new pulley and taper insert will be vastly cheaper than...

Put it this way, you’d need more money than sense to go chasing after variable speed pillar drills without very good reason. Far better off getting a used Fobco and tidying it up. Give you a lifetime of use then the same for whoever gets it after you, long after the variable speed trash has failed.

You’d have to be specific about the drill you were looking at.

I would have thought with the advent of YouTube woodworking as a hobby has probably never been so popular. However, as every year passes there are less and less full time furniture makers etc., a trend also seen in the USA. All these tool manufacturers that are going hammer & tongs certainly...

ww Presumably your drill press has pulleys at present? Even with a VFD you still have to use the pulleys, depending which speed range you want to work in. That’s why variable speed lathes generally have 3 pulley settings. You can’t leave the pulleys set to high speed and then turn your speed...

And I would very strongly suggest you don’t wind an induction motor up to 70/80Hz unless it’s specifically designed for such. Most are 50Hz UK with 60 maximum. Most standard induction motors are good for +20% speed increase above stated spec (IEC regs), but that all depends on the load being...

To the OP. There’s a few things to consider. I work in commercial BMS controls and have long since lost count of the number of motors and VFD’s I’ve fitted and replaced. If you change to single phase, your inrush current when starting the saw will greatly increase. Mine (3HP table saw) needs a...

Personally, it’s racing green every time for my Record and Stanley planes
