1950s 12-Inch Saw

(1/2) > >>

Model 12:
I located this Hitachi Saw. I'd been without a big saw for some years.
The model number PS-12 suggests it's a 12" saw. The specifications rate it 290mm; actually more like 11-1/2". The  nameplate doesn't have a date. I thought it was manufactured in the early 70s, but a fella I know at Hitachi says this was made from 1950 till 59.
It looked to me and a friend like this Hitachi 12" was used not too often and  for not too long. And then it sat in a shed rusting for decades.
Had to use a bolt extractor with a lot of the screws. Carbon Brushes were a surprise, looking pretty fresh. I do love that pipe handle.
WD-40 and me got the rusted blade off and I set it in vinegar. Got a sort of covered tank for that set off some from the house. It was in there a few weeks. The bolt and flanges too.
The Aluminum housing, handles and such had been painted when it was manufactures. I could see painting it was right for it as well.The old paint came off with brass wire wheels set in a drill chuck. I painted using this Aluminum colored paint for Aluminum alloys.
Separating that Steel shoe was downright easy. I knew it had been painted, but rust was so bad I couldn't tell what color. It set in vinegar for about three weeks. Finishing with removal involved some diligence with SS wire wheels and brushes set in a drill. I painted with silver rust proof.
The bottom of the shoe is left for another story.
She sounds and runs real good. But of course she needs a new blade. She's got a 1" arbor. I would have liked to use regular 5/8" arbor 10-1/4" blades. I've still got some left from the Milwaukee 6460 I had.   [//size]

Bill Houghton:
Nice.

Those big saws are useful and scary both.

Model 12:
Thanks Bill.
Yes, useful cause I need to cut 4" in one pass. This has a depth of cut of 4-3/4. I replaced the spring that retracts the lower blade guard right off. Fact is, I check if that thing is operable before I cut.
I got a new blade for her.
This saw sure eases into things nice. When I'm ripping I have to start off before I can set the fence. She acts like a regular saw for that. Definitely is precisely right on with the shoe and blade. I could tell that right off.

Omeomai:
Does the motor smoke or make lots of noise?  I'd think the brushes would have deteriorated after all these years

Model 12:
Hi there omeomai,
I'll tell ya, I've been right surprised how wrong such an expectation as that has turned out.
Right off I checked the carbon brushes like I said earlier and they sure looked like they were in the early stage of use.
And when I tested her with that old blade I couldn't believe how good things sounded. And she was cutting a 4-Inch depth all the way down better than 12 foot of length. I put her away and ordered a new blade.
I've had difficulty with getting a better fence; given the shoe's width, but mostly cause of that extra wide slot. 
Seems the fence for the current model 12 Inch saw fits just fine.
The first two picture shows how it fills that slot.
Third shows the fence is plenty long to fit across the shoe without over doing it.
