no previous part Part 1 of Drum/Thickness Sander series Part 2: The finally is almost here. »

I’ve decided to build a thickness planer. There are many posted here on LJ’s and I’ve looked at a lot of them. (maybe all, at least all I could find)I’m not far into the build and have a few questions for the guys who have been through this already.

-
-Thank You for all those that posted their builds. The ideas and processes have been very helpful.
-
-

-
the drum will be made from 5” maple disk. Total sanding width will be 18”
-
-

-
I seen one model built with the pulley built right into the wood drum. The more I though about it the more I liked the idea. This allows the drive force to be on the drum itself. The shaft is no longer driving the drum, the drum drives the shaft, which is just there to keep it in place.

-

You’ll note the drum hasn’t been trued up yet. My original plan was to glue 2 un-drilled ends and turn it on the lathe, but once I got that far I realized there was a good chance the holes wouldn’t get lined up right. I’ll true it once its on the base.

So a few other questions.
I plan to set the pivot point of the deck on a full length 5/8” shaft at the back of the unit. I’ve got a few pieces of harden shaft laying around and figured the full length will help racking a little.

I also figured I could make a series of holes so the shaft could be pulled out, and the deck could then be moved to a lower or higher position for thicker or thinner pieces. My concern is I haven’t seen this done, and it seems logical. What would the negative be?

There is one sander made that has a plexiglass dust shield. I like the idea, but plexiglass is getting pretty expensive locally. Besides the “cool” factor, what are the advantages?

I was thinking of painting (easy Smit) the sander, maybe a machine grey. Thoughts. Should I paint it or leave it natural and just oil it.

For now I only have a 1/6 hp motor. I know that won’t cut it, so I need to find another. What is the smallest you would use, and what’s recommended?

And here is truing up the drum
-
-

Here is the deck, all glued up.
-

And as the glue was drying I made the scissor lever for the height adjuster. I got them cut and welded together
-
-

-

And progress otherwise.

-

-

Not much left to do until I get some sand paper and decide on a motor

You’re off to a very impressive start. Are you going to use velcro paper or wrapped? I’ll try to remember to check the HP on my 18/36 Craftsman as it seems to have plenty of power and runs off 110.

I’m probably going to wrap it to get it working, but plan to use Velcro.

I also have nothing to add except moral support and probably a little heckling.

Cool, Don! I’ll certainly be following. I was really close to building one as well, right up until I found my older Performax 22/44 Pro on Craigslist a few months ago.

I will say that it has a 1.5 hp motor and I can certainly see why the newer ones come with 3 hp motors. Quite often, despite taking the usual small moves, even on narrow stock, the feed roller will slip quite a bit, acting as if I need a little more power to push it through, even tripping the surge protector a few times. That’s no big deal, and it’s certainly sufficient, but it does go to show that bigger is better, in my opinion. I wouldn’t opt for less than a 1hp motor myself.

Interesting project, I’m sure you’ll have fun and learn a lot during the build process. I hope you keep posting updates for us all to see and learn from.

Good luck with it all.

Nitpicking answer … Only that when you true up the drum using the abrasive sheet on the deck method, you’re heading for absolute parallelism (Is that a word?) betwixt deck and drum in first position. That could be marginally lost with the other holes. Having said that, I wish I’d done it!

My motor is, I believe 1.5hp. It’s probably specified somewhere in my blog It works well with that, but I wouldn’t want anything less.

By the way the blog’s had nearly 51,000 reads!

Thanks Stewart. As you were typing I was looking at your blog. Probably the last 10 or so reads have been mine.

I was thinking about the absolute parallelism (my brain wasn’t using that exact terminology though), but I figured I’d get that on the first hole, after that I’d get “close enough”.

How does the single rod adjuster work? I was thinking scissors to be more consistent.

What if you used something that already had accurate holes drilled in it.Like say angle iron or something?

Don, I checked and my 18/36 Craftsman has a 1.5 hp motor which works well for me. If you take way too big a bite it will trip the reset but otherwise does not bog down.

Thanks gfadvm, I’ll see what I can come up with.

I’ve added some pictures from today’s work. I made a couple steel rods, one for the motor mount which got mounted and one for the deck. That still need some work.

Brandon, I’m thinking on your idea. I’m not sure what’s available, but that may be an avenue.

Hi Don,
When I built mine I used 3/4” birch plywood for the drum. Pretty much cut the blanks the same way that you did.
I waited until the whole sander was assembled to sand the drums so that they are perfectly parallel to the bed.
I used a 12” wide X 16” long piece of 3/4” plywood and spray glued cloth backed 80 grit sand paper (had to buy extra wide rolls)onto the plywood. Sliding the home made sled w/ sandpaper back and forth on the bed raising the bed a little bit at a time made the drum parallel to the bed.
I use spray glue and thin strips of duct tape to hold the cloth backed sand paper on the drum.
Made 2 drums so that I didn’t have to keep changing grits for rough and fine sanding.

I will see if I can find the plans on the wife’s computer and forward them to you. Bare in mind that these were second hand plans when I got them so they may be a bit rough around the edges. Got them from this old woodworker friend who made acoustic guitars and smoked like a chimney. Great guy but you could only stand being in his shop for a few minutes because of all the smoke, “LOL”
