Enjoyed watching the changing from cheap to great bushings ! Your variety of polished rocks look very nice. I like watching your jewelry making vids. Some people like the less fancy version of rock jewelry ! Some people go over board with all the layers of fancy with them. Enjoyed watching 🤩
This bearing modification should make the motor and belts last a lot longer since everything is running much easier and smoother without occasional resistance from needing oiling Etc. Brilliant!
They've held up well. But, honestly, I shelved the unit after I made my newest tumbler so I haven't been using it for a full year. Still, it's ready and waiting when I want it, again.
I have one of these - sooooo noisy! I wrapped electrical tape around the sides to make the metal pieces firmer against each other and it did quiet it down!
That I would not know. But I also didn't realize that Harbor Freight has a second tumbler option. Next time they send me a manager's special coupon I'll have to go pick one up and find out.
I’m on my third central machinery tumbler in just as many weeks. First one ran just over 24 hours, the second lasted just four hours before the motor quit, and the third has roughy 30 hours run time so far. This time I’m under loading it and only running a single barrel. I just don’t want to keep running back and forth to HF.
ugh! That's awful. I'm intending to pick up the new brand of tumbler when I get another manager's coupon, but thanks to your warning I'm definitely getting the protection plan.
I wish I could tell you. I used a standard step drill, if I remember correctly, and just went one step at a time until the bearing fit tight. As with most things, it might be a good idea to test fit on a spare piece of sheet metal or even plywood.
those cheap bushings are exactly why I have stayed away from the 33b. I have 3 Lortone 3a's running 24-7 and they have much better bushings in them but, only half the capacity
Iv always been puzzled as to why the mfg companies don't have ball bearings already installed on these rollers🤷🏻♂️ I understand the motors with crap out over time and I understand wear and tear but why not prolong the motor life/rollers.
Plastic bushings are probably like 5 cents a piece vs maybe 30 cents each for metal one (these are literally numbers I made up). By 4 per machine that's $1.00 saved per machine. Multiply that by a million machines and the company makes an additional 1 million dollars. That's why companies do it.
I'm sorry, I don't know the reference. I don't remember seeing this anywhere else. I kinda wish I had, because it'd be a lot easier than doing it through trial and error.

Thanks! Yeah, overboard with fancy definitely isn't my style. 🤣

I haven't run the unit a ton since the modification, but it is running much smoother.
I don't own any Lortone tumblers I use tummlers tumbler because so east to change all the parts. Informative video keep up the good work.
If you can get your hands on one. Every thumlers I've looked into has been very backordered.
Easy to change the parts how do you remove a broken pulley wheel off of an r - 2
A year later, how are your upgraded bushings doing?

Good idea!
I wonder if the rollers are the same size in the Chicago Electric and harbor freight's new line Central Machinery double tumbler 🤔

what measure did you use for the step drill?

Sometimes it's worth half the capacity to stay away from cheap parts. I was surprised, however, at how easy it was to replace them.

I hear you. On/off switches and bearings over bushings seems like they'd all be a standard.

@@derrickfoster644 totally makes sense👍🏻
Gee wonder where you stole that idea from....

From the very first guy who replaced bushings I guess?
