Introduction: Drill Press Sanding Drums
Show All Items
A couple of weeks in the past my pals made me a gorgeous birthday reward: a large, strong and strong drill press. As quickly as I assembled it I knew that will were an unmissable instance to get my arms grimy and construct one thing! I made up our minds to make a few sanding drums to make use of with the drill to refine edges.

Now let’s cross have some a laugh!
Step 1: Materials and Tools
This construct is very best for a newbie, as a result of I used affordable, readily to be had fabrics and easy techinques, however it may be very helpful for everybody.
– First of all you can want some picket. I used some scraps of 18mm thick pine forums I had laying round, however I imagine the type of picket isn’t a very powerful, neither is its thickness.
– Then you’ll want a metal rod or one thing else to mean you can chuck drums into your drill press. I used an M8 threaded rod, you’ll use a stiffer rod, or an extended bolt, or the rest that may go well with the aim.
– nuts and washers;
– picket glue;
– other diameter holesaws;
– random gear.
Step 2: Let’s Make a Bit of Sawdust!!

Our sanding drums shall be fabricated from a variety of stacked disks. My drums ended up being nearly nine cm tall, even though possibly part of that will were sufficient. So we need to make those disks the usage of a holesaw. Diameter is slightly arbitrary, I went for a 65 and a 45 mm holesaw.
When you get this accomplished, get started gluing the entire disks in combination, the usage of PVA glue. Spread some on all sides after which sign up for the disks, till you succeed in the peak you wish to have. Then clamp the whole thing and let the glue dry. Be cautious to not use an excessive amount of power when clamping, or you can squeeze out an excessive amount of glue, getting a weaker bond.
If you personal low high quality hollow saws (like I do) chances are you’ll wish to true your drums up just a little bit, to lead them to as sq. and as vertical as imaginable. The larger drum wasn’t too tough, so I simply chucked it into the drill press and sanded it with 60 grit sandpaper and a sanding block. The smaller one required just a little bit extra paintings. I used a drill lathe adapter to show it, smoothening it out with a chisel, then I delicate it with sand paper. You can see the variation between the sanded one and the tough one in % five.
Step three: Now for the Rod!

While you watch for glue to set, you’ll get ready the rods that can grasp the drums. You could make such rods in a variety of alternative ways, however for me, the fastest one gave the impression to be this: I took an M8 threaded rod and lower it to duration. Then I litterally screwed the drums at the rods I had lower, and stuck them with nuts and washers.
This step may just finish right here, however I made up our minds to head just a little additional: possibly it is simply me, however I used to be afraid that, with extended use, threads may just chunk into my chuck, ruining it. That’s why I filed threads clear of the a part of each and every rod, which will get chucked. I additionally filed easy each and every sharp edge.
Step four: Add Sandpaper

At this level we are nearly accomplished, we simply have to connect our sandpaper. Anyway I feel it is higher to take yet one more precaution, to stop sandpaper from slipping when drums rotate. With the assistance of a sq., hint a line from best to backside of your drums, seeking to make it as vertical as you’ll. Clamp drums in a vise, then, the usage of a hacksaw, make a slim lower alongside that line, being attentive to attitude the noticed blade in opposition to the other way of your drill’s spinning means: see 2d picture.
Now lower a strip of sandpaper extensive sufficient to hide your drum, and lengthy sufficient to wrap it totally and overlap a couple of millimetres. Spread glue on one drum at a time, insert one finish of sandpaper strip within the slot you simply lower and wrap tightly. I used some tough rubber bands to carry paper towards the drum whilst glue dries.
All that is left to do now’s casting off rubber bands and feature a laugh with our new do-it-yourself sanding drums.
TIP: When it is time to exchange a wiped out sandpaper strip, simply warmth it up with a heatgun till glue melts once more and exchange with a brand spanking new strip.
I am hoping you discovered this instructional helpful. If you might have any query, please go away a remark. Be protected round your store and feature a laugh!
