I have the same part that came in a box of saw parts with my Highland Park 10" I just though it was a stray part will have to try it out. You learn something everyday just read RTH forum.

I think your saw is a later model, from right about the time contempo bought HP.

oregon - Thanks to your original post, I finally made one of these for our HP 10". Made the bearing leg on it longer than the top leg, but seems to be okay. If not for your post, I would've never known about this part. Thanks.
beefjello - I assume you must have one of these saws, right? If you - or anyone else - has one of these OEM parts they don't need I'd like to have one. It's easy to duplicate, but it would be cool to have the original part.
@jadedvision - Thanks for the post definitively ID'ing the part. Some of us were going merrily down a completely different trail... .

great discussion here but a photo of a Great Western slab saw may add fuel to the interpretation that it could be used to swage a blade (too!) www.threeriversgemandjewelry.com/greatwesternlapidaryequipmentco Scroll down a couple of rows of photos to see the bearing over the blade. Above is the blade dressing/blade sharpener bearing. Jon Hall said the bearing on the hinge was to dress the blade, and be less wear on the blade then cutting through grinding wheels. After cutting a lot of stone slabs, the blade dulls, the machine runs harder, and cuts slower. Usually you have to cut through a dressing stick, or grinding wheel to remove a thin layer of metal to expose diamonds in the rim. The bearing is attached with a bolt onto a piece of metal behind the blade on a hinge. I haven't used one because mine is missing the bearing, and 1 other part. The ad in Lapidary Journal from the 60's & 70's said it sharpens while slabbing, so you don't have to do another step. If you have info on how often you use this against the blade, please send an email to threeriversgems@hotmail.com Dec. 2016 Thanks to Joel McConnell of Julian,CA for this photo! Perhaps HP was so smart the designed a part with two functions. I was researching Great Western Equipment because I recently traded for a GW cab machine with some unique (in my eyes) features. More on that later. |

just because this topic came back up, and I recognized the part: Vince hummingbirdstones2 - You had said in this same thread in Sept 2021, that you you'd like to have one of these? Just a heads up to you. |

rockpickerforever - Thanks for the tag! I'm not a FB member, but Robin has messaged that seller. It would be nice to have the OEM part.
For the amusement of all you "make it work" types on here, I have already fabricated one. Only had 1/4" round stock, so a sheet metal sleeve made it fit the hole in the saw vise. Had a random bearing or two lying around, so two nested pieces of rubber tubing made a press-fit "bushing" to hold the bearing on the rod. The part I made is longer on the bottom leg where the bearing rides up against the bottom of the saw table. I might like that better than the OEM.
You can also see the beginnings of my cross-feed handle. Drifted open the end of an eye-bolt and mangled it into a comfortable orientation. Will cut threads to where the handle bend is, then cut the original threaded end off to length. A hole drilled into the threaded end (for a pin to fit the corresponding hole on the vise) and it will do.
Could have waited until I got 5/16" round stock - but I wanted it immediately...!!!

You're welcome, Robin. Vince did what my husband would have done (make it, lol). I hope it was still available. Maybe I just should have sent an email to you?
Regardless, it is always nice to have the OEM part.

oregon - Thanks for posting the original link to the saw parts. Now I just have to wait to see how the original one stacks up against my imitation.
Peruano - I'm gonna' have to try the bearing swaging trick someday. I remember hearing that discussed some time ago. |

some of the other parts were for that saw also - I think the 'slab guide'? looks like the ad is down, so maybe you got them all... fun to make the connection for a wayward part

Yeah oregon , I thought about buying the slab guide (fence?) too. Looked at the size of it, though, and it looked like it was for a 6" saw. The spray shield he had on there definitely looked like a 6" model, judging by the measuring tape beside the fence.
I already built a fence for our 10" saw, so I passed on that - and all the rest of the parts. Someone else must have snagged them.
EDIT: Emailed the guy with the parts and got a direct link to his ad. The other link went to a "group" page. |

Hey oregon , how much weight are you using with the gravity feed? scientifically determined two hunks of steel that came with it! I just redid this saw, will put it up for sale soon, so don't have a lot of experience with it. Cut a couple slabs by hand today, then with the gravity feed. Weight probably depends on the saw, the drag on the main bar, and the brass guide, and how hard I jam the bearing attachment in (above) all contribute to the friction, so... I think there's probably 3-5 lbs on there? Personally I'd rather see things cut slowly with a nicer cut than fast with a rougher surface. Not sure if that helps you.
for reference, catalog shows coffee can with sand. Powerfeed option and canopy hood. Just have to figure out how my canopy can fit with the deflector on there.
