Hello all! I'm fairly new to tumbling and recently received my Lortone 33b from the Rock Shed (along with two more barrels for stages 3 and 4 ). My question is about the offset nylon washer. When the tumbler is running, the barrel(s) creep up toward the nylon washer until the barrel is rubbing against it. Am I going to need to replace the nylon washer every so often, or is there something else I can do. Thanks.  |

Mine does rubs against the washer you are talking about. Make sure the metal lid is touching the washer and not the bottom of your barrel. My 33b has been running constantly since September and I have not had to replace it yet.
So don't worry about the washer, fill those barrels and have fun.

Will do Jason! And thanks for the quick reply. I have the barrels placed so that the metal washer on the lid is rubbing on the nylon washer as you stated. Very first batch (5 pounds of medium sized rough from the Rock Shed) went in two days ago!
Thanks again Jason!

You will have to replace the washer periodically as friction takes it's toll. If you allow non OEM parts in your house, you can try what I did and use a metal washer from your local hardware store. I put a bit of lubricant where the metals rubs(my two barrels meet each other at their bottoms.
PS...there have been threads where people go to great lengths to successfully eliminate the barrel drift. I usually just put something under the low end to reduce the force of (and therfore the damage done by) the friction force

They should last at least as long as the shaft bushings. You can order them along with bushings/belts as needed. You can probably find nylon washers at local hardware if needed right away. It looks like they only keep the drum from rubbing against the frame.

Thanks for the replies! I'm probably going to get a little bit bigger size of nylon washer from the hardware store along with a machine screw and maybe a bushing. I'll leave the screw a little loose so that the washer can rotate on its axis when the barrel rubs up against it. Thoughts? |

Mine have been running for over a year wo any issues. I'll just rotate them to a fresh spot when they wear through.

Too bad they departed from the trusty ol nylon nut and metal flange for a guide. Looks like the current nut works fine. If you are worried about it wearing down, maybe consider oiling to cut sown on the friction.

You might check the window and sliding door parts at your local Home Depot or Lowes. I use rollers for a sliding glass door and mounted them on my mega tumbler frame. Granted my set up is on a larger scale then a 33b but you should be able to find a smaller roller/wheel that you can adapt. I have been using these rollers for over a year now and no sign of significant wear. I put a drop of 3-in-1 oil on them occasionally. Here's a picture of what I use...  Rick |

Yep! That is exactly what I was thinking of doing. I think I might actually have a small wheel from an old door. Thanks!
