Hello Everyone -

Got a JET 16-32 drum sander and thought about buying the JET extension tables. However, my shop is getting crowded and the extension tables would take up valuable space. Instead I decided to make foldable extension tables as shown in the photo above from scraps found around the shop.

All the parts of one of the FOLDABLE EXTENSION TABLES is shown above. Note that the INFEED and OUTFEED extension table support frame is not the same size. This is due to the fact that the OUTFEED side of the drum sander is longer.

What is shown is the bottom side of the extension TABLE TOP (top left), the SLIDING TABLE FRAMEWORK to which the table top is attached (lower left), and the SUPPORTING FRAMEWORK that attaches to the frame of the drum sander (lower right). Above that framework are the bolts with a wooden spacer that attaches the framework to the drum sander and the pivot bolts that are 1/4×20 carriage bolts. The 1/4 inch plywood prevents the carriage bolt from spinning when the wing nuts are tightened to hold the tables in place.

If you want to make one, start by making the SUPPORTING FRAMEWORK that attaches to the drum sander frame as shown in the next picture.

The SUPPORTING FRAMEWORK consists of the BACK BAR that uses threaded inserts that line up with the existing holes in the frame of the drum sander where a purchased extension table would attach. I used 3/8 inch bolts about 2 inches long that I already had and a wooden spacer about 1-1/2 inch long. I could have used shorter bolts but was too frugal to buy some. As it turned out, this arrangement made the bolt heads more accessible when it came to attaching this assembly to the drum sander frame.

To this BACKBAR was attached the SIDES of this assembly. The sides were notched out to fit around the BACK BAR and beneath the notch a slight angle was cut to match the angle of the stand. A top piece was added between the sides and the dovetailed SIDE GUIDES were attached to the sides. A 1/4 inch slot was cut into the sides between the SIDE GUIDES. Everything was just screwed together with sheetrock screws.

The following picture shows the SUPPORTING FRAMEWORK attached to the drum sander.

The following photo shows the parts of the foldable extension table; The SLIDING EXTENSION TABLE FRAMEWORK (top) and the underside of the TABLE TOP. The molding attached in a “U” shape to the bottom of the table top hides the gap that results when aligning the table top to the feed belt of the drum sander.

Inside the SLIDING EXTENSION TABLE FRAMEWORK is found the conformit screws that are used to adjust the table top and the hex head bolts are used to fasten the table top to the SLIDING EXTENSION TABLE FRAMEWORK illustrated with the next photo. The green spacers are used to make sure the bolts don’t go through the top of the TABLE TOP.

A closer look under the TABLE TOP in the next photo finds 4 threaded inserts into which the hex head bolts thread to hold the TABLE TOP to the SLIDING EXTENSION TABLE FRAMEWORK. Beside each threaded insert is a 3/8×1 inch metal wood joiner that protects the TABLE TOP which is MDF coated on the top side with melamine. The conformit screws bears on the wood joiner when adjusting the TABLE TOP.

Below is a view of the assembled TABLE TOP and the SLIDING FRAMEWORK that shows the supporting arms that slide into the SUPPORTING FRAMEWORK that attaches to the drum sander. The edges of the melamine MDF top have hardwood edges that adds durability.

Time for putting it all together …

This is the EXTENSION TABLE in the UP position. The table top measures 16 inches by 12 inches, not including the hardwood edging. Wing nuts hold it in place.

This is the EXTENSION TABLE in the half-pulled out position. I guess that in this position, it could support longer, lighter items to be sanded.

This is the EXTENSION TABLE in the stored position.

And this is what it looks like with both extension tables in stored position.

I finished the EXTENSION TABLE with WATCO Danish Oil. The dovetail sliding surfaces were coated with paste wax.

Now, if you’re wondering what goes in that big space under the foldable tables, check out Jet 16-32 Drum Sander Storage Cabinet.

I hope you enjoyed my description of my solution to the Jet 16-32 drum sander extension tables.

Any and all comments welcomed.

Thanks for looking.

Great job and thanks for sharing. How would you rate the JET 16-32? The wife and I have been considering a drum sander for a bit now.

Wow, talk about blueprints. Thats about the most information ive read on any shop project. Very informative. Looks great, we should be able to adapt your ideas to other tools such as a saw or thickness planer. Are you happy with the way the open end sander works. This is on my radar.

I’d like to thank those that have commented on this project.

As for how I like it? Don’t know. Haven’t had a chance to use it yet … been building this stuff for it. However, from all that I’ve read and recommendations from others that own it, it should be a great addition to my collection.

It is solidly built. Goes up and down easily. And from what other’s have told me, if you have to sand wider (than 16 inches) a small adjustment will give good results.

If you’re planning on getting one, you better plan on getting a dust collector unless you already have one.

Got a chance to use the drum sander today. Set it up per owners manual. Used it to flatten a glued up board. Just kissed it on each pass and sometimes ran it twice without changing the height adjustment. Lowered it just a QUARTER turn at a time and worked perfectly. No burning experienced. I think I’m going to use this a lot. Get one if you haven’t yet.

Another great idea!! Seeing as I just purchased my 16/32 sander I will be copying this also. It is too bad the jet table do not fold because they sure do take alot of real estate. Great solution!

Great work and fantastic idea which can be used for similar type machines. I have a 16/32 sander and will be borrowing this idea for my machine if I may. Have used my machine for couple of years now and its been absolutely great and enjoyable machine to use. Well built and although a little finicky to set up the vertical drum level and parallel to the bottom as no shims are supplied, once its set it seems to be great and work well.

To say that I’m impressed with this would be an understatement. Very thoughtfully designed to provide accurate table heights, durability and ease of use. I could never have come up with something like this on my own. I will surely be making these for my new DS. I also liked the cabinet solution which is along the lines I was thinking. Thanks so much for calling this to my attention. I wasn’t too interested when you first posted this, but I sure am now!
