I've got a small joiner i purchased for next to nothing at a sale. I'll
have to take a closer look, i don't know the brand or the diameter of
the cutter unit. It's about 4" wide i believe. I'm trying to figure
out how much motor i need, what rpm, and what belt ratio to use. I'll
probably never use it for more than red oak a max of 1" thick. Any
ideas with this limited input?

We knew what you meant. If your jointer allows you to take 0.125" off
a 4" wide piece of oak, you'll want 3/4 HP. 2 Pole (3600RPM) or 4 pole
(1800 RPM) doesn't matter, just change the pulley ratio. Ball bearing
motors are nicer than bushings but they're more money. US or Canada
made motors are usually better quality than off-shore ones. Again,
more money. You DO want an enclosed fan. Baldor makes nice motors.
My Dad had a jointer. It's probably still in his garage, under a few
things. He'd run more or less all his edges through it after sawing
them, taking off a very thin layer in a pass. We also used one in shop
class, again for edges. All of this was when the world was young, of
course, and my experience was limited even then. But the bit above
My question is this: Is an eighth-inch really a common (or safe) amount
to take off in one pass through a jointer? Especially across the face of
a 4" board? And why would you do this? How rough would the wood need to
be to require the removal of that much material? Or would thinning the
wood out be the goal?
The usual caveats apply , which can be summed up under the general
heading of "my woodworking ignorance".
I would not take 1/8" of with one pass but if your jointer will do it it
will have plenty of power.
Additionally the only surfaces you truly want to run through the jointer
are one edge and one face. If you run both edges and both faces you are
wasting material if you expect to end up with parallel surfaces and edges.
When preparing the surfaces of wood the jointer is only intended to
create flat "reference" sides and edges. Use those reference surfaces
to correctly create opposite parallel surfaces with a thickness planer
and a table saw.
I have a similar jointer, and haven't yet gotten around to running it.
A 1/3-1/2 HP motor was suggested in this thread:
(That is a web-based mirror of the wRECk.)
Are you saying the motor on it needs to be replaced or there's no
motor on it at all? If there is a motor, you can probably get it
rebuilt. If no motor initially, then I'd suggest having a look at some
comparable new models of jointer and buying a similar or slightly
heavier duty motor that's on the new ones.
My wife picked up a 50's era 4" jointer years ago at a garage sale
(Yes - I am a LUCKY MAN!). It was mounted on a home made wooden stand
with a 3/4 horse electric mother of unknown origin. The motor was
fine for that machine because the bed was too narrow to put much
strain on it even when surface planing. That little jointer was a
good example of the tools that Sears/Craftsman provided in the early
years. Solid, well made and heavy.
BTW - I think jointer and Joiner are both OK and used interchangeably
in some WW magazines.
Stick around a while, and you will have heard joiner and jointer used
interchangeably. While as you pointed out jointer and joiner are two
different things, then and than are very often used in place of each
other and most are not thrown off track by the miss use of those two
Now if you really want to get picky, keep an eye on my posts, where
every fifth word is misspelled, and try to figure out what I am saying.
And if you take a fifth of all the letters required to correct the spelling
errors, and jumble them around 5 times and take a fifth of the words they
spell, you'll get a cryptic message that not even Leon understands. :-)
Yeah, I know. A joiner is a machine used to cut slots or holes for
biscuits or similar "JOINING" devices. However, I have heard and seen
the word joiner and jointer used interchangeably for about 35 years
and it never bothered me as much is it seem to bother you. The
primary purpose of the machine is to prepare edges of lumber for
