I am trying to avoid coil springs all together Any particular reason for this? Vibrasonic,minisonic, loto (sorta) all use them...
These tumblers all have asymmetrical constraints which I imagine contributes to the rolling motion. Seems like mounting your shaker off to the side should provide the offset for the motion?
Do you need the "45" anchor point on the left? (Thinking out loud) what about just having the hopper suspended from a frame, with your shaker mounting tab off to the side? Not sure, there's probably a reason to have the bowl more constrained? certainly easy to try while you're constructing the 45 design. It'd be nice to compact that design some, maybe the 45 leg could go straight down after a short horizontal run, or even wrap back around under the hopper ala the "J" bar of the minisonic...
(Thumlers vibe (which I don't have) but folks seem to like it a lot - this vibrates in a horizontal direction rather than vertical , food for thought)

I'm guessing that was a felt washer to keep stuff from hitting the bearing. Seems like waterpump bearings were popular to use on smaller trim saws, lots of those are press fit. Did you remove the SNAP ring already? It could press in/out either direction like Larry said, (wo seeing the bigger picture.) Might be the shaft has to be pressed into the bearings and they will come out of the saw together. See if you can read the numbers/manufacturer on the seal (england 1591?) might get a hint if you can find that bearing.
Were they noisy? seems like a lot of work just for a clean up? 2c.

I have one of these sitting on the bench, IMHO, I'd start over instead of copying. sheet metal is near worn through that rides on the rails on this one, and I never liked how tightening the bearings relied on flexing the metal tabs that hold them. Split nut hole is egged out(again thin metal) which causes binding/alignment issues.. Rails have some flats worn on them too on this saw...
They were fine saws, probably built/designed with cost effectiveness in mind for the not so serious, casual home use. Fit those criteria well for the time.

disconnect the motor and take an old cord and wire the motor direct and see if you get power that way . I have had 2 of those switch's go bad on different saws Second this, if there's 120V to the motor and it's not turning, open up the gear box to have a look if hardened grease or a broken gear is keeping it from running.

check voltage to the motor (or wire it direct) and check the resistance of the winding, shouldn't be zero (shorted) or infinity ( open). Most often the gear box is full of old hardened grease, clean it and relube. There are other 3-5 rpm motor alternatives, just have to be creative to fit it inside the original switch box. If you're convinced the old one is dead and your going to toss it out, I'll send you a postage label and you can drop it in the post to me. Good luck. I don't have experience with fixing motors... I checked the resistance at the two wires leading into the motor. Is that where I should check the resistance of the winding? It was neither 0 nor infinity. I think it was around 4 mega ohms. 4 MegaOhms doesn't sound good, probably should be 10's of ohms, I have an LS-10 on the bench, here's it's motor, 30 ohms. always easier to make sure you're reading the right thing if an item is disconnected from the rest of the circuit, i.e. disconnect both wires (or in this case, at least one)

Hi, My LS12 auto feed motor died recently. I found an old thread about this that suggested checking to see if the switch was the problem. I've checked it with a voltmeter and it is fine. What would my next step be to fix this? I also searched for motors online and found only a Highland Park link that said out of stock. If I need a new motor, would that be my only option? Thanks in advance! check voltage to the motor (or wire it direct) and check the resistance of the winding, shouldn't be zero (shorted) or infinity ( open). Most often the gear box is full of old hardened grease, clean it and relube.

Traditional glass fishing net floats are hard to come by, but some modern glass artisans make quite elegant alternatives. For the Millennium they hid 2000 up/down the Oregon coast, It's become a tradition, but limited to the Lincoln city area...

Mini-Sonic barrels mounted on the top table of a Vibrasonic that seems to deliver oval vibration motion: so could you just mount a flat piece of scrap steel between the vibrasonic table and your hopper mount that extended out the back, bolt the magnet shaker to that? - the vibrasonic spring mounted table should be able to handle that - you know that system works as is. - bolt the plate with the magnet closer or further away to experiment? - The linear vibration would be offset from the support springs so should produce some sort of rocking motion?
- simple

>>> There is a more complicated geometry than expected. I suppose the nut on the big spring is for adjustment ? yes >>> Looks like 2 separate moving entities, the springs under the hopper, and the 180 degree strip spring system with 1 coil spring for driving the vibration. The lower set of springs are pretty flimsy, I'd venture that rather than adding heaps to the motion, this was added to keep their units from being loud, and more for keeping them stationary! The lotto needs 80 lbs or whatever to work, remarkable that this thing can shake about the same amount of rock and not walk off the bench after a couple days running. yes, I don't think the the rubber grommets on the left provide lots of motion, just enough to allow the 'J bar' to rotate. The rubber dampeners on the right do allow some. There are all sorts of these available, check amazon for example... >>> imagine if the electro-magnet could be adjusted from 30hz to 300hz instead of the fixed 60hz coming from the wall socket...and the shaking pattern can be altered at the same time... Don't you have a variable frequency drive in your stash? I *think* some of those might be able to go above 60 hz? but I'm not sure. >>>Thanks again for that photo. That makes the few expletives worth it, Dang cold weather made the plastic case non-compliant, and cold fingers... Figured it's an elegant solution. ie yeah, few wear parts! Cheers, Rick

here are the guts of a mini sonic, forgotten the whole thing was mounted on another set of springs, wonder what that does. But the linear motion is near the middle (the tension in the middle is adjusted to change the action (spring force as well as the electro magnet?) But flexible mounts on either end , so you can see how the rocking motion is achieved. I think those rubber mounts with bolts embedded in them are readily available. I know I changed some out on a chain saw last fall and they weren't that expensive.

Serious oregon ? And this plunger head works in a Lot-O ? Amazing. That might be the trick ! Is the handle wood or fiberglass ? Does the handle screw into the plunger head ? Is the inside of the plunger head smooth with no gussets or sharp corners molded into it to trap rocks ? Yeah, mine is threaded, rubber as heavy duty as the lotto barrel or heavier. I picked this up new for a buck, but at the time home depot carried the same plunger. Not surprising if they no longer carry them, they were about triple the price of the cheapo plastic version. good smooth bowl. But besides bowl shape, I think you both are right to worry about constraining the vibe motion, or transforming a linear motion to a 'circular' rolling one. So my impression is that a counterweight on a rotating shaft produces a circular motion, The Vibrasonic hoppers are free to vibrate in a circular motion more so than the Lotto which is more constrained to be a rocking motion. Just grab them and try to move them by hand. The minisonics might be a better model, they start with a linear motion? must be a picture with the cover removed somewhere.
I can't think of any reason that 3000 rpm (50hz) would be the optimum tumbling frequency, so It'll be fun to see how this progresses.
Still, can't you do this as experiment 1...

if you don't want to worry about bowl design, I have a heavy duty plunger that I use in my lotto, drop in replacement with a slightly larger opening. hmmm, used to carry them at Home Depot, but I don't see it online any more.... www.plumbingsupply.com/professionalplungers.html But can't one of you just bolt a butt kicker right to the top flange of the lotto?

Only thing on it is Model 6. Anyone ever see one of these before? It's brand new, never used and was found collecting dust in garage or some such. mystery solved? Beacon Star.

The question now is, is it worth it to continue it for someone who is probably not going to generate a whole lot above maybe a thousand or two in sales during the year? They are not leaving us much of a choice I guess - I don't want to reach this point next year and suddenly receive a 1099 for a bicycle I sold on Facebook.
yeah, I see this as the real problem. I've also been trying to de-stash, am pondering what to do. There are lots of caveats, but it's probably all going to boil down to having meticulous records, and learning how to file business taxes. e.g. if I sell a car via ebay or one of my collectible Curta calculators, that'll generate a 1099. As I understand, Ebay's 1099 will simply be gross profits; that will include expenses you paid them in fees, shipping, fees on the shipping, fees on the sales tax they collect... so without bookkeeping the Gross profits = profits I think.
Yes, if you were selling for profit you were already obligated to pay taxes on these types of activities. I have to look up more of the distinction between a hobby and a business, but my quick understanding is that generation of a 1099 may take that choice away from you, the 1099 would represent your income as hobbies have no room for deductions etc.
Sounds like Ebay has already been loosing a surprising number of buyers (as well as sellers), that's kind of a sign as there is probably more buyer protection there than anywhere. It'll certainly cause a mess next tax year for a lot of folks I imagine (as well as the IRS). $600 seems like a ridiculously low threshold here.
(I didn't mean for the original link to be a definitive source, that was simply the first link on the google page I had open)

Just curious if anyone's who's selling online is thinking of changing prices, selling modes, quitting etc due to the new income reporting laws?
Basically, any 3rd party goods/services payments totaling over $600 for the year will generate a 1099 income form for you. That'll quickly make a lot of hobbies businesses... Ebay,Etsy, Facebook Marketplace, paypal, venmo etc.

Just a word of caution, The most prevalent use of these 3" motors seems to be for fan applications. This provides critical cooling to most of these motors as well. I acquired a bucket of 3" motors removed from service, and just spent a few days testing them on a QT6 to see if they would work. Most all of them ran until they got too hot, and a couple cut out with thermal overloads. The lortone motors tend to run hot as it is, but these were generally hotter. I believe the original motors have an internal fan, but I'm not sure. I have a very old Scott Murray NOS motor that does. I do have a couple 110/220V capacitor run versions that seem to run very cool wo a fan though, maybe that'll help you out, imagine you'll need a 220V version. I think you're better off with a PSC motor than a shaded pole version for heat generation as well... I'm sure some HVAC expert can correct all my mistakes.
I've also noticed that there are far more motors with 5/16" shafts rather than the 1/4" that lortone uses - The pulley's have plenty of material to drill this out to fit the larger shaft. 2c. Good luck.

Fees are about 10% and I sell with free ...
Those numbers on your screenshot are closer to 15%, if you're factoring that into initial purchases. Both Etsy, Ebay have a way of divvying up fees to make them appear much less, same as items priced at 99.99 instead of 100.
I can remember when ebay was $0.25 per listing and that was the only fee... I keep figuring they'll run out of ways to stick more costs to the seller, latest being they force you to let them manage payments so they can hold that revenue for several days before paying out. I think that was how late nite TV commercials (albums, Ronco etc) made money back in the day. I just figure 20% there now, right back to where a traditional auction house commission. I guess that's capitalism, if you're not increasing profit, you're a dying company.
I imagine etsy is on the same trajectory.

The round label i t6hink is the machines label and being round on that type of machine i think its an older Crown machine from in California yep, you can still make out Crown on the round label spot. missed that.

I have a friend who acquired this old grinder but it needs to be rebuilt because it's in pretty tough shape. I can't quite make out who made it but I can read "Salt Lake City" on one of the old emblems. "Dowse Lapidary Supply Inc. Utah's biggest finest rock shop" etc. I bet that's the dealer label, probably and old beacon star, Star diamond, diamond pacific or such...
