Curtis Posted December 26, 2018 Report Share Posted December 26, 2018 I know a few people on here have drum sanders and specifically the supermax's. I just picked up a 16-32 last weekend and it has a noticeable rattle. Is this sound troubling to those who have one...or normal? Thanks! Here's a link to a video of the rattle Quote Link to comment Share on other sites More sharing options...

It was doing with the sandpaper in, i took it off to see if it was the paper, but it was still doing the rattle shown above. Quote Link to comment Share on other sites More sharing options...
Tpt life Posted December 26, 2018 Report Share Posted December 26, 2018 That is not normal then. Bearings are a concern. Checking set screws on keyed pulleys seems to be wise after a few other machines on the forums seem to have missed the threadlock. Quote Link to comment Share on other sites More sharing options...

Ill check the set screws but I definitely just sent off the vid to Supermax (ahem Laguna). Quote Link to comment Share on other sites More sharing options...
gee-dub Posted December 27, 2018 Report Share Posted December 27, 2018 My 19-38 is spooky quiet. The transport belt motor is louder than the drum. Quote Link to comment Share on other sites More sharing options...
..Kev Posted December 27, 2018 Report Share Posted December 27, 2018 Does it make the same rattle when actually sanding something? ie, under load.. Quote Link to comment Share on other sites More sharing options...
Byrdie Posted December 27, 2018 Report Share Posted December 27, 2018 I'd say there's a playing card stuck in your spokes. Seriously. The older guys on here will know what I'm talking about. There's a piece of sandpaper or a thin sliver of wood or something else that's rubbing up against a rotating part, probably a gear, and it's just stiff enough to make that ratcheting sound. That sound doesn't make me go straight to bearings. Bears are more of a rub or a screech than a click. Quote Link to comment Share on other sites More sharing options...
Tpt life Posted December 27, 2018 Report Share Posted December 27, 2018 Unless one ball or roller is gone. Then the rest clack. Not guessing. I have heard it a lot. Just hard to diagnose from compressed phone audio. Same clatter happens if the races that are supposed to hold the rollers or balls have too much slop.

Which is why I asked if it made the same sound under load. If there were something stuck in it somewhere, it would make the same sound under load. If it were a bearing issue, it would be a different sound or perhaps no sound at all. Quote Link to comment Share on other sites More sharing options...

I'm guessing the drum is out of balance?. I noticed inside the drum there are small black weights stuck in there which I'm guessing were used to balance the drum? Does yours have much vibrattion when running ? Mine doesn't pass the nickel test. I can't hear the belt conveyor motor until I shut off the drum motor It does continue to rattle under load. And I am def old enough to have had a topps baseball card in my spokes Thanks everyone Quote Link to comment Share on other sites More sharing options...
wdwerker Posted December 27, 2018 Report Share Posted December 27, 2018 It could be slack in the abrasive strip. If it’s not tight it makes a flapping sound. I’ve been running a 16/32 Peformax for over 20 years and the 19/38 for maybe 1 1/2 years. I’ve got the dexterity to take the tiny bit of slack out but it’s not easy.

Chestnut Posted December 27, 2018 Report Share Posted December 27, 2018 The plastic playing cards worked better or at least lasted longer in my spokes.... There is something wrong not sure what it is but if it's new i'd make sure to follow up with Supermax (laguna) or the company you bought it from. If it id it out of the box i'd be taking it back for an immediate exchange imo. I have no tolerance to buy a tool never get to use it and be stuck navigating warranty work. I'll add to the list of people that say their sander is spooky quiet. DC off i can't hear it through ear plugs. Quote Link to comment Share on other sites More sharing options...
Gary Beasley Posted December 27, 2018 Report Share Posted December 27, 2018 Check the alignment of the motor to the drum. It has a union between them that will make a racket if misaligned or worn. If thats good my bet is on a bad bearing. Quote Link to comment Share on other sites More sharing options...

I have tightened everything they asked me to tighten and it does it with paper on or off. My biggest concern is that the noise also comes with a wobbles which obviously would affect accuracy and consistency. 17 hours ago, Chestnut said: The plastic playing cards worked better or at least lasted longer in my spokes....

Guy from Suoermax on the phone wants me to try all these fixes, seriously....I have put 8 board feet through this. Quote Link to comment Share on other sites More sharing options...
bleedinblue Posted December 28, 2018 Report Share Posted December 28, 2018 My 16-32 had a misaligned motor and drum, but it did not make this noise. The misalignment was bad enough to break the motor drive shaft. It took me too long to get Supermax/Laguna to fix it. Filing the initial claim and all communication was easy, but I had to get mean to get them to ship the needed parts. It took a couple weeks IIRC to get them to ship. We all love our Supermax sanders and Laguna bandsaws, but their customer service sucks. It is the biggest reason I chose a Rikon bandsaw last year.

Guy from Suoermax on the phone wants me to try all these fixes, seriously....I have put 8 board feet through this. When I buy something like a Grizzly jointer, I expect to have to fiddle about a bit with some adjustment or even a possible replacement part like my fence that was out of spec. I am paying 40% or more below the price of the competition. It would be silly of me to expect a top-shelf product at a discount price. That is not a viable business model. The Supermax sanders are not a discount line. They should arrive ready or darn-near-ready to go. It is our responsibility as consumers to hold sellers accountable. They should just ship you a new machine and let you get on with your life. I did cringe a bit when I read about the Laguna sale. Laguna has a long running history of wide swings in their customer service quality. They have swung from "walks on water" to "can't get anyone to answer the phone" over the years. Maybe they are at a low point in their customer service biorhythm. This is not your problem, it is their problem. Unfortunately, getting them to respond properly is being made into your problem. Please keep us in the loop so that others can factor their performance in to their future purchasing decisions. 1 Quote Link to comment Share on other sites More sharing options...
Gary Beasley Posted December 28, 2018 Report Share Posted December 28, 2018 Did you buy it new or used? New I would take it back and demand a refund or replacement with a checked out machine. Wobbles just dont make the grade and means a serious defect. Quote Link to comment Share on other sites More sharing options...
drzaius Posted December 28, 2018 Report Share Posted December 28, 2018 What that sounds to me like is the shroud on the motor hitting the fan. It doesn't take much of a bump to shift is enough to just touch the blades. Doesn't sound like a bearing at all to me. If it's just the shroud, it's an easy fix. Anything more than that & I'd want a different machine Quote Link to comment Share on other sites More sharing options...
gee-dub Posted December 28, 2018 Report Share Posted December 28, 2018 I went back and listened again after drzaius' post. That would sure be a simple thing to check; three screws and the bell-cover comes off of my 19-38. Quote Link to comment Share on other sites More sharing options...
Tpt life Posted December 28, 2018 Report Share Posted December 28, 2018 I guess I made a leap. I assumed visual inspection had already been completed. Shrouds being hit will show impact marks and wear. I agree the sound is not a bearing wear noise. It could be an improperly set or assembled bearing though. The idea of internally set balance weights on that drum also has merit if the visual inspection I assume was already done turned nothing up.

Curtis Posted January 18, 2019 Author Report Share Posted January 18, 2019 Just wanted to update everyone. Ended up being ball bearing issue and since it was practically new, Supermax (ahem Laguna) is giving me a brand new one. Im glad I bought it from my local woodcraft as I went in, inspected inspected one on the floor , showed them a few videos and they were helpful in making sure the unit was replaced. So now just have to get this sucker up my basement steps and into the car and exchange it. 1 Quote Link to comment Share on other sites More sharing options...
