Looking to purchase a double drum sander, or perhaps a single drum. Educate me with pro’s and con’s. Open or closed, I need to learn. I lean towards open for greater capacity. Thanks for the input.

I’ll be glad to start the responses,

I own a SuperMax 19-38 opened sanded and it’s a fantastic machine. That said, if I would have had the extra floor space and electrical capacity to dedicate to a larger closed end dual drum sander I would have purchased the General 36” dual drum sander in a heartbeat, it was only about $800.00 more than the supermax at the time but required a dedicated 220V circuit and floor space was already limited in my shop. The reviews of the Supermax sander are all very positive and I completely agree with them, it’s probably the best open ended sander on the market currently.

I’ve used a General Internation 24” double drum sander, (closed end) and it worked pretty well when it was working. The problem with most drum sanders is the paper fastening system. Drum sanders are really hard on abrasives, and I hear a lot of complaints of people that get their paper ripping out of the clips on the end. The system most sanders use is lacking, in my opinion, the GI model I used included.

That being said, I’ve had really good luck with my own drum sander that I built – I’ve only blown up (tore) the sandpaper once, and that was because I didn’t fasten the ends before I started. If you’re up for the challenge of building one, I think they are totally worth the cost savings, satisfaction, and they really work well. There’s a TON of information here on Lumber Jocks on building your own should you want to do so. (Shameless plug for myself: I made one too, and blogged about it :-)

Otherwise, I think that Grizzly has a pretty good looking line of double drum sanders. Never used them, but as with most machinery, a lot of companies sell the exact same machines just rebranded with their name on it (I think this is the case with the General sander I used to run)

I always seem to have a P.S.

Biggest money saver that I’ve found when it comes to keeping the paper from ripping off the drums is to simply wrap a couple rounds of strapping tape around the ends of the drum. This keeps the paper IN the clips or stuck onto the velcro. Sandpaper in those long rolls is expensive, and once it rips, you end up replacing the whole long strip.

Obviously this method wouldn’t work on the “open” end of an open end drum sander…

I have a SuperMax 25” dual drum sander (closed) This is a 240V, 5hp machine and works great if you have the space. The clips hold the sand paper securely. I never had the paper rip or come of the drum. This is the only drum sander that I have ever owned so I can’t tell you how it compares to other brands.

I have 2 Jet drum sanders…a 22/44 and a 16/32. I have had the 22/44 for about 10 years and the 16/32 for about 3 years. Both have been vert dependable and have worked flawlessly. The only time i have had the sandpaper tear near the end clips is when I try forcing it to sand more than I should and stress the machine. Since i have learned to adjust the amount of wood I try to sand I have not had this problem. The amount of wood and the type of wood make a difference.

I, too, have the Supermax 25×2 closed-end drum sander. I’ve never had the paper tear, but I miss-cut once and just took it off and sewed the extra piece on with a zigzag stitch on my sewing machine. I wore out the sandpaper before it ever tore or broke. I have friends with open-end sanders (Jet I think) and they say that they have difficulty getting the drum perfectly parallel to the bed and when they turn a wide piece around to sand the other edge, it shows a line.

My Supermax is old (back when it was still called Performax Supermax) and made in the US. I think the Supermax now is made elsewhere. And the last time I contacted their customer service over a year ago, they were rude and not helpful. My conveyor stopped working and my husband was able to fix it for me with assistance from the LJ community.
