Buddy of mine picked up this old jointer at a garage sale and never used it. He said I could have it for what he paid (I think he mentioned $20). I can’t find a name anywhere on it, except the pulley says “chicago Casting”

Once I clean it up more maybe I’ll find the make of it. But, I was thinking of finding an electric motor and building a stand for it. Think its worth my time, even if I have to spend $100 on a new motor? If so, how many HP and RPMs should I be looking for? I was thinking between 1 and 1.5 HP and 1800 RPM?

A 1/4 hp washing machine motor is fine
for a 4” jointer. Such motors are pretty
easy to find at garage sales and such…you
gave go with a 1/2 hp motor if you like
but any more would be overkill, imo.

As I recall you want about 5000 rpm on
a jointer cutterhead.

oh wow, good, that’ll cheapen the cost significantly then.

Once I locate a motor I’ll do the math for the pulley’s and get the RPM’s I need. I’d just like to be able to identify this relic so I can maybe find some blades for it. Its got blades in it, but I’m sure they need to be replaced.

It almost certainly takes a fairly standard 4” blade such as these Freud blades.

Good Luck and

So, i have in my mind just a little cart or benchtop device – motor mounted below and offset some so shavings don’t fall on it. Not sure how to deal with belt tension – was thinking of having slots for the motor to mount in and jack post to tighten and align it.

Here’s what I did. I used a 1/2 hp motor that runs at 1725 rpm. It cuts ok if you go slow. 3450 rpm. would be better.

If you approach a hundred getting that up and running you could just buy an old Delta or Homecraft 6 inch jointer and have something better with parts availability.

I agree, I think my buddy will want $20 for this one and I’m hoping to find a cheap motor somewhere… But I need to look this one over and see if its 1. worth it and 2. a brand name, which will help justify any money spent on it.

A few more pictures…excuse the mess…we just moved plus the wife is my busy with 101 projects as well.

But, things actually aren’t too bad – everything moves nicely and freely – looks like just a good cleaning, some new blades, oh – and a motor and I’m hopefully in business. I really enjoy restoration of things (it’s usually motorcycles) so look forward to getting this going.

As far as name – NOTHING. Every part is cast with a part number and such, but no make. I thought I saw something so I took a brush and started cleaning and here it says “FRONT” – I’m guessing it has something to do with the infeed section or something. I find it odd I can’t find a name – It hasn’t been repainted by the looks of it. I’m guessing a department store type (maybe Montgomery wards/western auto/sear) type of thing? It’d sure be nice if someone came along and told me what brand it is and how awesome it is and worth a pile of money :):)

Looks like this one. Found it on foils image search.

I couldn’t give away one of these in my area.

Good catch. Made by AMT for Sears and appears to be identical to their model 4232 4” jointer. According to the manual, a 1/2hp 1725 rpm motor with a 4” pulley is recommended. Cutter (arbor) speed should be ~3600 rpm. It also has bronze sleeve bearings, so make sure they are well oiled before using the thing… might want to pull the cutter head and inspect just to make sure they are good before spending more money on it.

Cheers,
Brad

thanks Brad – so bronze sleeve bearings – no roller bearings and I’m assuming pressed in… I’ll inspect that before doing much more. The wife loves rustic decor and has had me make black iron pipe lamps and such – I caught her eyeing this up last night… I guess if its not useable as a tool, she’ll end up hanging it on my livingroom wall haha.

Anyway, never heard of AMT, but I know back in the day Sears tools weren’t all that bad – if this bad boy is still in tolerance and with a fresh set of blades, will I get reasonable results (mind you, weekend warrior hobbyist here and mainly work with soft woods…)

Thanks

AMT had some good and bad stuff. I have a 16” scroll saw from them that has served me well for 20+ years.
Nothing fancy, but it works.
Sleeve bearing do require some maintaining, but last a long time. Lithium grease.

I have made a few of these over the years from
a 2×4 and a few plywood scraps. 2×4 is
ripped to 2×2 and legs crosscut to I think
3-5 degrees on the ends in two axis, so
beveled 3 degrees and mitered 3 degrees.

The plywood braces are mitered at 3 degrees
on the ends so the legs are splayed out in 4 directions.

The motor is mounted on the bottom on
a hinged flap for tensioning the belt with
motor weight. A rectangle of plywood added
to the top with a hole or two holes in it
for chips to fall out and for the belt to travel
to the motor.

I may have misspoke… the manual shows two different versions of that jointer… the 4232 and the 4232B, with the former having sleeve bearings and the later having ball bearings. There doesn’t appear to be any oil caps for the sleeve bearings, so it would be difficult to tell what is in there from just looking at the pictures. Guess you will have to open it up to see what you have.

As for lubrication of sleeve bearings, a good 20W non-detergent oil (like the 3-in-1 electric motor oil in the blue bottle, not the red one) will work well. I am not sure if I’d use a lithium based lubricant on them. Bronze bearings work by forming a thin film of oil between the bearing and shaft, so the shaft basically ‘floats’ on the layer of oil. It needs to be thin enough to flow freely around the bearing surface. The manual says you should give a few drops before use and every 15 minutes or so of prolonged use.

Cheers,
Brad

Sounds good. I’ll start screwing with this after a I get a project done or if I have extra time. I really do not want to spend good money on a motor – so I have the word out to my friends and family that frequent CL, garage sales and just plain old have alot of junk laying around!

As for whats in there – as long as they aren’t pressed in too badly I’ll be ok. I get the sleeve thing – same as motorcycle crank shell bearings.

I even considered configuring my bench grinder to run it – I think its doable, but the bench grinder is 1/3 HP and 3600 rpm. But, it would be slick if it worked because its only $30…
