Hi everybody.

After lurking on this site for awhile, I thought I’d do the right thing and join up. I just picked up a used table saw for $50 on Craigslist. Getting it home was a bit of a nut-buster, since I only weigh about 125 lbs., but I am still intact.

Let me start by thanking all of you. With very little searching in this forum, I have positively identified the saw as one made by Mao Shan. Most of the labels are long gone; the motor’s name plate reads “Central”. I thought at first it was a Grizzly 1022 knock-off, but now realize it’s kinda the other way around, since Mao Shan apparently was the real name behind the Grizzly machine. Whatever. I don’t need no stinkin’ labels; I just wanted a saw with a cast iron top, belt drive, and a decent motor, which I now have. Yay!

Now, my query: I have already cleaned off most of the rust on the table and all the stuff “under the hood”. Other than (possibly) replacing the motor bearings and tuning up the alignment (it actually works OK as is), what else should I do in terms of quality control? I don’t like the stamped steel wings, so they are going in the junk pile. Ditto the fence and rails. They’re not worth restoring IMO, because I know I can buy or build better ones; should I worry about the integrity of the trunnion and lift/tilt mechanisms? Seems to me if these work OK then there’s no need to fuss with ‘em any more. Thanks for reading; I look forward to your responses.

Didn’t mean to upload this image; don’t know how to delete it. Just think of it as a sexy preview. More to come…

Here is a close up of the front labels, or what’s left of them…

Maybe an old Harbor Freight Central machine

The word “Central” implies “Central Machinery” AKA Harbor Freight. The name you’ve found is probably the root Chinese vendor for both the griz & HF variants.

Your sexy pic appears to be a ghost of a Griz “G6025” data plate, the style says griz too.

It seems silly to put a $400 Incra TS-LS incremental fence on a $50 scrap saw but if you want the silk purse out of a sow’s ear then that will do it. Put a good freud LU83 blade ($50), a new drive belt ($20), a digital height gauge ($60) and an Incra M1000 miter gauge ($150) on with the Incra TS-LS ($400) and you’ll get excellent results ($680) from any saw ($50) where the blade doesn’t wobble much.

Thanks for this. All very much on point. I just bought a dial caliper and magnetic base at Harbor Freight today. I have never measured runout/blade wobble (same thing?), but based on what I’ve recently learned here and elsewhere, this tool should give me a pretty good idea of how straight my saw is cutting. If it only needs minor adjustment, loosening a few bolts and applying a few deft hammer blows should do the trick.

But Grizzly no longer stiocks the arbor for this saw, So basically, if mine is really out of whack I may be looking at a very large paperweight, and there is no use throwing good money after bad by purchasing the upgrades you mention. If, on the other hand, the saw cuts reasonably true, my intention is to do exactly what you advise.

And kudos for the label decipherment! I squinted hard from every angle and could make no sense of it. Now I do see the “G6025.” I’ll look into that.

if you do decide to toss it for scrap… keep the handwheels and associated acme threaded rod (at least, I assume it should be acme thread). I would keep the cast iron top as well. Could later reconfigure to band saw table top or something.
