Drum/ Thickness Sander
Fergus OMore:
Doing 'the shopping' at Aldi and Lidl. Next week, Lidl has a pillar drill for £49.99. I've got one when Aldi's had them( probably the same). Looked at mine and thought that I could put it on my lathe saddle. Mebbe bit of fiddling with the cast iron base but dead useful. Thought that you might be interested

Squares II: Return of the squares
I spotted the middle with a spade bit.
I'm cutting off the excess so there's less to turn. It's also probably safer to be doing less of an interrupted cut.
And drilled all the way through. I need 23 of these and i've made that and one spare. I'd actually spent most of Saturday thinking about how i'd drill a 20mm hole without a 20mm bit, until I remembered I had the spade bits hidden somewhere.
I've also figured out how i'm going to hold the paper on. At first I was planning to use hook and loop sandpaper, but it's extraordinarily expensive. So I'm going to leave the two edge disks unglued, but held on with screws, so that after they're turned round I can remove them and cut segments out, and use the cutout to retain the edges of the paper.

Simon when roughing out squares to circles on the bandsaw, drill a tight hole in a piece of scrap for a nail, and press it through. Turn it over so it stands vertical, point up. Clamp the scrap to the bandsaw table with the nail sticking up. set the distance of the nail to the blade to equal the rough radius you want. Then put a hole through the center of your blanks for a slip fit on the nail.
To use, put a blank on the stationary nail axle, and rotate the blank into the blade to cut the circle. This works best if you have a groove for a miter gauge in your bandsaw table, and put a tongue on the bottom of the scrap base so you can slide it in toward the blade, rather than just clamp it. You can then cut circles of any diameter, just by sliding in or out.
You can also cut cone segments this way by tilting the table to give an angle cut.
And you can cut rings this way, too.

Thanks for the tip but I don't think that'd work so well with my bandsaw. The blade likes to drift about so I need to cut freehand to try steer it. It's a pretty lousy bandsaw in general, the whole thing shakes as it runs since the three wheels are pretty far eccentric. Still beats using an upside down jigsaw!
A better bandsaw has been on my list of things to build for a while now. I think I still need to tidy up the garage a bunch after finishing this sander though. Still got the dust collector to finish, and I need to find a place to keep that bike (i'm thinking about strapping it to the ceiling).

Nearly gave myself a hernia today trying to push the disks on.
Ended up making a rubbish reamer to get the holes a bit bigger. Now the whole stack is glued up and drying.
Been having trouble sleeping the last few days, spent an hour in bed thinking about how to re-arrange the garage to fit more stuff in. If I move that tool chest Rob Wilson gave me behind the drill press, I could fit the planer and sander onto the short bench at the back of the garage. It'd also put the chest in a more convenient location. I can barely get at it where it is now.
I've been using that corner of the garage as a sort of dumping ground for 'stuff that looks useful', as in stuff that will never be useful, so I'll make a trip to the tip at some point. I'm also still considering getting rid of that sheet metal forge. Or at least cutting it into chunks that can be hidden under a bench somewhere.
