I have found several postings regarding drum sanders but so far I have not found answers to questions I have.
I currently have a Delta Drum Sander 31-255X and I’m far from happy with it. However, I’m about to make some changes/upgrades to it and hopefully, it will resolve my issues.

Often as I’m sanding the drum will stop rotating and the belt is slipping. My first attempt to resolve the issue is to replace the belt, this has been ordered and should arrive this week. I ordered the belt from https://www.biedlers-belts.com/ The current belt is well used and has slipped numerous times. If this does not resolve the issue I will try changing the pullies and belt to a synchronous-belt and pully system. I’m assuming I can get the pullies of the correct diameter. I’m not going to worry about this until I test with the new belt.

Currently turning the crank to move the table up/down is much harder than it should be. I’ve completely disassembled the sander and lubed the corner post. All corner posts seem to turn freely when I rotate them with the belt removed. A few years ago I was able to use another identical unit and it was very easy to raise and lower the table by turning the crank. Any suggestions?

I’ve ordered and received a kit from Grizzly to convert to a Hook and Loop for the drum, see https://www.grizzly.com/products/Grizzly-Hook-Loop-Conversion-Kit-for-Model-G1066R-and-G1079R/H5037. I’m now waiting on the sandpaper I’ve ordered (3M Hookit Purple Clean Sanding Sheet Roll 334U, 30701, P600, 70 mm x 12 m, see https://www.amazon.com/3M-30701-Hookit-Purple-Sanding/dp/B005RN7WDI/ref=sr_1_1?dchild=1&keywords=3m+34442&qid=1603727188&sr=8-1) before installing the conversion kit.

Ultimately if I cannot resolve the issues I will be in the market for a new drum sander.

When you had it apart, you checked the corner screws to the table, but did you turn the crank without the belt on to see if it moved freely?

I have had one of these for several years without any problems. I use it mostly for end grain cutting boards so it takes a lot of shallow passed on that hard wood grain to get a smooth finish which I usually still have to clean up fine scratches with a random orbital sander.

My biggest complaint is the sand paper mounting clips which are difficult to use and easy to bend out of shape. I like your idea of hook and loop which I may look into.

I looked at the 3M paper and I would be concerned about those tear off sections coming apart on the drum type sander.

As far as the table asjustment I would have to suggest reviewing the manual to see if there is some misalignment that you missed.

Your corner posts don’t use a chain?

Generally machines with moving tables use a chain to keep the sprockets moving in lockstep. If one of the sprockets is set to the wrong tooth, one corner could be low or high and that could cause a problem.

There have been a lot of reports of difficult issues with those Delta sanders.

It’s cogged belt, I think. I sold mine about 10 years ago and don’t remember all the details, but there is a tension adjustment on that belt (or chain, if that’s what it is).

I had a similar model and sold it, same problem. I could never keep the adjustment screws in time with each other.

Yes, I did check the crank without the belt and it did turn freely. Before installing the belt I also ensured that all four corner screws were at the same height using a digital caliper.

Mine has a toothed belt (I’m not sure what to call this type of belt) that slides over a toothed gear/wheel attached to each corner screw. Also, in the path of the belt is a tension adjuster.

Yesterday I received two new belts to drive the motor to drum. Only one is used, I ordered the other as an extra.
I tested today and it seems that it drives the drum better and it seems that I had less binding, e.g. the drum would stop rotating BUT I did encounter one stoppage. It seems that the depth of cur MUST be very shallow and a slow feed speed should be used.

Thus the new belt did NOT resolve the issue.

I’m now leaning toward getting a new drum sander.
I’ve seen some great reviews for the SuperMax, see https://supermaxtools.com/products/wood/19-38-drum-sander-71938-d/

I’ve not look to see what else is available, I’m open for suggestions.

I have none past the Supermax. I had sold my Delta, and went without for maybe 6 years, then a need for a DS popped up again. I went straight to the Supermax 19/38, and frankly it’s way ahead of the Delta in terms of features and quality. My biggest complaint if that Laguna moved the production overseas, so it’s not USA made anymore. Even so, the one I have is very good.

Thanks, Fred, I’m sold on the Supermax 19-38. Currently, there is a small sale where I can get about 10% off. I’m looking at the 19-38 with the DRO and infeed/outfeed tables.

After a bit of research, I think the Wixey WR510 Digital Planer Readout and the DRO offered by Laguna are the same. Can anybody confirm this? I found one source the Wixey at https://www.tigersupplies.com/Products/Planer-Digital-Readout__WIXWR510.aspx?invsrc=adwords_ts&gclid=CjwKCAjw0On8BRAgEiwAincsHAX7Ca7HcERAz_MF4VBpxyR9fBZjSmU4qLYZnw2k4nY-zCPPearjWxoCT9sQAvD_BwE for $53 BUT I think it does NOT include two brackets. I don’t think it would be very difficult to make the brackets. Any suggestions?

My Delta 260 X5 has been trouble free and excellent for the past 10 years. If it ever gives up the ghost I’ll definitely consider the Supermax. Being 59 now, it may never happen based on my experience so far. :)

No idea, I was unaware that Laguna offered a DRO. So I searched it and found one…it was clearly labeled “Wixey” on the front vertical bar.

I recently bought a Superman 16/32. I take it there has been an upgrade has the DRO built in.

What I’m most impressed with is the dust collection.

You mentioned switching to hook and loop. I have a DIY DS and went with hook and loop. It was a mistake. It works fine for end grain, but for surface sanding if you do not have very consistent feed it will make a dip in the work where it pauses or slows.

This is interesting feedback and has me thinking I don’t want to do this. On my current Delta I DO NOT have HnL and don’t always get a nice flat surface, I think it sounds like what you have encountered. Because of all the other issues I’ve not look for a solution. So far what I have been sanding was not critical and I just lived with the issue also I assumed it was related to the poor performance of the sander.

I might take a closer look and see if I can resolve this but at this time I have too many projects and cannot take on another one. However, I will NOT install HnL on the Supermax until I do more research. Much thanks for the FB.
