Hi,
I have a 6" jointer that needs a motor. The manual does not talk about the
horsepower required for the jointer but it does say that it needs to run at
about 4000 rpm. It states that I can take a motor that runs at 1725 and put
a 7" pulley on it to get the 4000 rpm.
I have a 1/4 horsepower motor running @ 1725 rpm lying around. Is it too
underpowered for this jointer?
Thanks
Alex
I have a 50's era 6" jointer with a 3/4hp powerkraft motor from the
same period. It works for full width but I have it set for a pretty
light cut which might make the difference, just under 1/32" if I
remember correctly. Balanced pulleys and a link belt really smoothed
it out and might transfer power better because I can push the stock
through a little faster now.

1/4 horse would be underpowered, especially if you aim to use the jointer's
full width capacity. Find a 1.5 or better with 110/220 V. Tom

1hp would be more like it, IMHO.
If I'm buying new motors (terrible practice, I know !) I find that
2hp are about the cheapest price break.

Sounds like you have an old American Machine and Tool jointer. They
came with two pulleys, 7" for a1725 rpm motor and a 2" I think for
3450 rpm motor. Motor did not come with jointer. 1/2 hp will run this
jointer easily. Very good machine if it's a AMT. Most of their power
tools were of okay quality, jointer is much better than average
quality. When you need blades 5/8"x1/8"x6" standard cutters are
needed. Everyone sells this size.My jointer is over 30 years old and
still performs like a champ with a 1/2hp motor.

how old is your 1/4HP? if it's old enough to be repulsion/induction it
may well be enough. if it's more modern it will likely be too small.
I think if I had it and a 7" pulley just lying around I'd try it. if I
had to buy the pulley I'd probably just go buy a bigger motor.
This is why we have Harbor Freight! You really need high power for face
planing, not much for edging.
