(looks like I was a few minutes redundant... Tommy good things are running again)
Yeah, the brass is considered a 'consumable' part...
can't tell from your original photo, but you need 'space' between the jaws fro the spring/jaws to work. Your photo below make it look pretty narrow. If the clamp or fatigue & wear has bent them slightly and the shoulders are meeting they're won't be much pressure. Or if a rock chip has lodged between the jaws that'll cause issues. The other photo of your jaws removed make the top end look not so straight, but they might have been cast that way, or camera parallax?
Most of these rods are 1/2-20, You could borrow a tap, put them in a vice (or in the saw with the clamp to cut new threads. if the shoulders are meeting, you could 'persuade' them back into a more open shape, or file the shoulders slightly.

I don't live in a hurricane area, didn't know such a tool existed.. if you use those barrels with heaps of wingnuts, get your self one of these wingnut drivers for a couple bucks.
(Seems like overtightening never seals the best so you might want to ratchet down your drill/driver)

thanks.
It's attached to 60lbs of sand, so I don't really want to ship. Need to thin out the herd. $180 ready to go. Just ran a load through it...

Will that shield slide right off? it spins freely right now but is trapped between the blade flange and bearing so I cant tell if it is attached or just slipped on. The steps on the shaft look like what AzRockGeek described. Shaft is .875" diameter. I.D. of bearing is .79 (14mm) and then it is turned down to 3/4" on the pulley side and tapped 3/4" on the blade side. Chuck
So did the flange just press off the shaft?
I have a NOS one of these, are these arbors that valuable? been thinking of using it for a not so serious project but....

I would love to go rock hounding with you and find what is in your photos oregon . about 50% I'm the primary finder. Seems like there's one estate sale around here with tons from a collector every so often. A different kind of hounding, But Figure I'm the secondary finder then Is that your first Sonic load ?Do your bearings have grease fittings or are they self lubricated ? Yeah, first experiment. I think it's the motor bearings that changed pitch, Have to investigate, but too many projects, and have to prep some more rough... The single long 14 pound original Sonic hopper I have will tumble long items like 3 inch diameter limb casts say 9 to 10 inches long. Call it a small log tumbler, it simply rolls in one rotary direction with no end over end movement. If you weld you can easily make hoppers for that beast. I could see a 24 inch long hopper say 8 inches in diameter for tumbling an 80 pound log quite easily. weld out of necessity, certainly not my forte. Any thoughts on a flatter container to do heftier specimen slabs with lots of smalls/ceramics?

fwiw,
I thought according to this old thread blade thickness was according to the core, but I just spoke with MK and it is indeed the kerf.
I've been through a bunch of MK blades over the years, generally satisfied. Replacing a 303 6" trim saw 0.032 blade, the new blade just seemed thin. mic says the core is 0.024 and the kerf 0.029" and I notice that the part number on the blade doesn't match the box. Wondered if I had a counterfeit or something so I called.
Thickness is meant to measure the kerf not the core. "the amount of material you'll remove."
All their (303 but assume others) blades are made in Indonesia.
part number on the blade sticker - was actually the part number for the sticker! (153690 vs 156907)
When pressed if 0.029" is within specs for 0.032 blade, I couldn't get an answer. That is like 10% less diamond so it'd add up over the course of production. Curious if folks have other new blades how they measure.
Might have to try some other unbranded blades again.

I'm about ready to see some Oregon window pane reflections from a Sonic. Or do you guys ever get sun ? do you have two 4 pound or one 12 pound or 14 pound hoppers. Cloudy, rainy here, artificial light. Two 4lb hoppers, Ran one load with random stuff, and endcuts/ceramics. Sorta followed the loto recipe. Different action, that's for sure. I can also see why you need production roughing to keep it fed....
Motor bearings *might* have sounded a bit different after a week, want to open it and double check the bearings again. Thinking of a way to attach a larger flat tupperware and try polishing a thicker larger slab.... Interesting the long thin piece of Tahoma was just fine all week, but I did a final 'burnish' with ivory soap for a couple hrs and that's when it broke, as well as one or two others - I guess the borax might also act as a cushioning agent.... Crappy photos, decent polish though it's not 'reflected' in the pics.
endcuts backs
endcut fronts

This is afternoon sun passing thru west facing windows. Tumbles are scraps from a glass blower. Hand held 2015 iPad Pro. Pure sunlight, no artificial added. Background paper dead white. THe gridded window pane reflection is classic

And the winner is... the only person who guessed a number in the 1700's... oregon ! Congratulations! The actual mileage was 1759.7 PM me your address and I'll get the box out to you today. here I was thinking I should google map it and come up with a reasonable answer, dumb luck worked with zero effort... I'm just super jealous that I haven't been out to Eastern OR yet this spring... sigh.

I did find the replacement parts for what came with my saw but it's obviously a lot of money Kicking myself for letting the get away - I packed it in a MFRB and had it in a shed at the family house we moved from a year ago. Folks living there now have done a lot of cleaning.
I imagine more small saw vises are in the landfill than on saws...

Thanks for looking and for the advice and suggestions, I'll just keep running it and try to keep a better eye on it while it's running.
So what would you guys' guess be if the rock tub solidified, dried out, or got wedged in such that the rocks could no longer move. Could a solid mass start the thing oscilating wildly? too hot & too much mowing to think about all the F=ma vectors and whether loose rocks would really behave differently. than a concrete chunk. 2c. Actually when you vibe your large rocks, if I recall lots of smalls, worked better than a mix with mediums? I can't remember exactly, but maybe that's an illustration of a large chunk being able to do more damage?

oregon - Forgive my ignorance but what vice attaches to the item above? I have a 1510 that seven years ago came with a gravity feed which I took off and somehow seem to have lost all the parts to it. I think it's just the stock factory vise on a rod. pictures are better the best I can do. Dug these from a few old threads.
My understanding is that the power feed just 'pushes' the vise for you. Cheers.

What size saw does it fit? yeah, I spent a bit trying to decipher Covington's site. the link is in the post above. They seem to suggest the kit is similar/same for the 1510 and 1100 series, but I'm just not sure? the Rod measures 18.25" from end to end.

It should work on many saws. It's an ingenious design. It worked great once I understood it. It has a clutch and will cut fast when not under a load and slow down when it is. I ruined the first clutch but got a free replacement from Covington (not the motor). Is the coupler on the end of the rod a clutch?

SOLD
This needs to go find itself a Covington Saw before I decide to butcher it for other projects. This is an older version from a shop closeout, never been used but a generation older. Slight surface rust on the end of the feed rod, but threads look fine. Plugged in the motor and it seems to run fine. Looks like the newer versions have an auto-cutoff rod/switchbox, That should be easy enough to duplicate. $150 + shipping.

I had 20/20 vision till I hit 40, then I started wearing readers. It got too bad for even them, so I went in and got some proper glasses-- bifocals. I'm not sure what I expected. I still can't see the computer screen right. It's a 17" laptop. It's not SO close. If I tilt to see the screen better, it helps but I can't do that all the time. Guess I'll need to go back to the eye doc and get a different script. Or something. I'm really ignorant when it comes to glasses. Maybe I'll just get another pair of stronger readers. *sigh*
yeah, my eye guy pulled out the chart when I first went in 20/20 was soooooo good.
reading focal point is about a foot, computer screens are usually more like two feet.
When you go in ask for a script also for 'computer' glasses, or tell them you do a lot of work in front of a screen. Ask for your scripts (they have to provide them to you by law) and then just order some single vision pair(s) off Zenni or somewhere online. Single vision glasses don't have to be fit to your face like progressives, so online ordering is just fine. They're cheap enough to have a few pairs lying around, and I grab my computer ones if I'm going to be sitting here for a while, way more comfortable to use. Likewise, if I'm hiking, or biking the progressive part just gets in the way, so I have some single vision lenses for distance and a tinted single vision pair of sunglasses. It also give me more chances to loose a pair of glasses...

Imagine you've checked the four springs. Was the load extra dry when you found it? Wonder if things dry out enough and the action on a big 'solid' mass could make for interesting happenings? certainly seems like it was violently shaking for some reason. Might be worth loading it up and turning it on for a few seconds with one belt on to see if the first belt failure might have caused it. Mystery indeed.
