Topic tags/keywords: craftsman sears king seely table saw jointer 6” 6–18” cast iron stand lathe rustic traditional

Good morning. I’ve come across an old Grizzly Cast Iron Jointer. 6” with a 48” bed I believe. It does have rust spots on it, and is being sold by an industrial machinery sales and repair shop. Ad says it needs a new motor. Unit itSelf doesn’t have anything indicating the model, year, voltage etc. she wi be sending a pic of the motor rage when she gets to work.
Now, I have some classic iron myself with a 50s craftsman king seeley table saw and a 60s sears craftsman 6-1:8 jointer.
I coverted the Table saw into a welding table because I needed
That, already have a
Hybrid in my shop and that motor is 3:4hp 115/230 volts, 10/5 amp,60 cycle 1 phase 3450 rpm and the innards still look good enough but copper is red now.
The jointer is 1/2hp 115vts 8.3amls everything else is the same both AC motors.
My question is, will throwing the table saw motor in their somehow not a good idea or not work? And is there anything I should know about any of the theee units before I Make a hundred mile trip for an old partially rusty machine. What should always be checked aside from bearings and belts? Where does the lubrication go for these two older motors? Any tips for the restoration? Anything I should know about these kinda of vintage in general? They are asking 150 for the grizzly, I was going to use the 3/4 and make my own electric wood lathe but a grizzly jointer sounds better when J already have a length and a depth lathe, jointers could really help my planer starting up my own milling and woodworking shop. Currently 70-75% of my time is going into driving to pick up wet timber and processing. I’ll build more than shop apparatus for sure Thank you in advance and hope everybody has a good day of woodworking ahead of them. First two pictures should be the jointer then table saw motor and the rest obviously grizzly stuff day,

The best motor would be totally enclosed, but.. does the motor sit under or very close the where the shavings fall? Can it be guarded so shavings and dust don’t get into the motor? That would be my concern.

Well, when you say “everything else is the same both AC motors” I’m guessing you mean speed and frame size as well. So you have nothing to lose by trying it. I agree about it would better if was totally enclosed, but my Unisaw only had a drip proof (not totally enclosed) motor and did just fine. I think you’ll be good with the motor, but remember you won’t be able to fire tat jointer up and try it out…so give it a good inspection.

Lubrication goes in the oil port located just above each bearing on the end-caps. Normally there is a cap or something covering it to keep crap from falling down into the hole, but not always. Use a good 20w non-detergent oil. 3-in-1 sells a motor oil specific for fractional horsepower motors – it’s not their regular stuff and is in a different color bottle.

If condition is unknown, it might be a good idea to open the motor up and check the bearing surface, and clean the felt wicks, as they are a dirt and grime magnet. You can rinse them in solvent (mineral spirits, alcohol, etc…), and then re-saturate them before re-installation. After that, you just need a few drops every now and then depending on how much you run it.

Now for the fun part. Over the years I have picked up many machines that the owner claimed had a bad motor. You can really negotiate the price down on them if they don’t work! Anyway, every single one of them has been a trivial fix – from just needing to hook up a wire that had broken loose to replacing a klixon (overload protector).

Cheers,
Brad

I guess I’ll point out that the Grizzly you’re looking at probably only exceeds your current jointer in bed length. So if that’s a huge factor in the lumber you’re milling, then maybe upgrading the bed length is what you need, and you could fix the motor or replace with the Craftsman 3/4 HP.

But I’d probably hold out for an 8” jointer.

I apologize for the late response. It being summer, well it’s busy for those of us in the construction trades, not to mention the shop needs attention. Too of course.
The picture of the motor was sent to me and it had stated a 1hp motor was currently on it. Being and I’m still new to the mechanical aspect of my hobby, I am just being a little cautious. I decided against the jointer, it is a rather far trip and will be holding off for something more like

But honestly, almost all of my dimensional lumber make
Myself from half or quarter logs during processing of lathe blanks. I think it would be more important to have longer blades than a Longer bed and may decide on a 10” benchtop and just use this extra motor here to make my own bowl turning lathe.
And Brad its amazing what people
Neglect. I’ve owned two Benchtop planers in the last year, total spent was 75$ between both units and about 140 miles to each spot and back altogether. Not bad at all considering the fix for either room less than an house (except trying to set the Delta blades not know there is a knife setter needed. I have just as much fun searching and finding tools as I do building anything
