No, haven't finished my first guitar yet( barely started it), but i have finished quite a few jigs and machines, the latest my drum sander.

what started out as a simple plan for a drumsander made out of wood quickly changed as my career did. I am now a part owner of a full metal shop, so it only made sense to modify my drum sander plans to be made out of steel.
i just gave ot a test drive on some cedar and some cherry just before taking the pictures and the results were very pleasing.

pay no attention to the background clutter.(i've been meaning to take care of that)

so without further ado here are the pics.

Wow!! Frank, awesome sander. [:Y:] You're brave for even tackling that. Looks like it turned out great!!! Do you have a pile of wood to send through it?

nice! just out of curiosity, how do you set the thickness? (I can't seem to see anything to either raise/lower the sander nor the table)

[:Y:] [clap]

olivier, if you look at the picture named height adjustement, you see 3 threaded rods connected with sprockets and roller chain, you also see that one of the threaded rods extend beyond the mounting point that's what i turn on to adjust the height i've been meaning to attach a wheel to the end of that rod for easy adjustment.

the 'legs' on the feed table is of such dimesion that it fits into the legs of the base, so they slide in the base, you can the same principle being used on the motor mounts for easy belt tightening.

And yes i've got a pile to push through it [:Y:]

edit: i also drilled and tapped the sprockets and fatsened them with a nut, so if in need of fine tuning on just one of the rods i just loosen the nut that locks the sprocket and turn just that one rod.

Frank,

That is one really nice looking shop-built sander. It looks really well engineered and built. Good job!

Frank, that looks great.

Now, don't change your mind on your body mold just because you own a steel fab shop. Stick with wood for that :D

thanks for the kind words.

Rod, luckily i built the molds and forms while i was employed as a carpenter, so yes they are wood.
i have never used a thickness sander before so i wasn't quite sure what performance to expect, but i must say i was pleasantly surprised. i thicknessed those pieces of cedar you see in the pics from an uneven 10mm thickness down to 5mm in just a couple of minutes and they came out with a tolerance of +- 0.03mm. i'm sure it will take a lot more passes to get that tolerance with hardwood though.

well Craig if you pay for the shipping from norway to australia.....

Might me enough to buy a small car. :D

Seriously, that is a very nice looking unit. One of the things that has held me back from making my own is the feed unit. What did you use for the feed belt, feed rollers, and what size/speed is you gear motor?

Steve, i've been very lucky as far as parts for this sander goes, everything was found in our shop except for the feed belt.
the gear motor(0,25kw 1,32A) has got quite the powerful gear on it, a reduction from 1400 rpm to 12 rpm and with my rollers that works out to about 3m/min( around 9-10 feet pr min). the rollers were parts taken from an old conveyor system. the feed belt i got custom cut and joined from a local outfit that specialises in wheels and belts for most industry transport needs, was expensive but worth it i think. its thick enough to get good cushioning so that i can set quite a bit of pressure on the drum.

Well Frank I did a few rough calcs. 1 set of back and sides hand sanded to final thickness from .130 . One top the same. Approx 20 Hrs at $50/Hr Package it up as soon as you can bliss . Seriously though Frank that machine of yours has inspired me to have a go. Even if it turns out half as good I will be overjoyed.

Craig.

I'm green with envy :mrgreen: well done I did a rough calc that the 1/3 hp motor with that ratio is 38 hp you could thickness whole trees with that if the main motor didn't stall
