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?
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.
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.

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.
