Thanks for the replies guys.
Didn't think any actually existed, you'd think the manufacturers would think of people like us!
Flettner if you could find one I would be happy - I'll keep my fingers crossed, but I won't hold my breath as it's been so long since I've seen any of those and I think the scrap merchants probably got most of them.
Plumba, yes the actual capacity doesn't matter it's just that they're around the size I need and I really don't want to have to get involved with trying to roll my own with a hammer, a piece of wood and a welder! (finished product would be a bad look). BTW maybe your father would be able to strike a deal with a fellow geriatric- what's he keeping them for? bet it's because 20 years ago he thought they might come in handy and now he's keeping them because the workshop wouldn't look right if they weren't there!

Prerotator motor, not really homemade, but interesting
My neighbours diary says I have boundary issues
Skin thickness wouldn't really matter as it'll only be something to contain all the ceramic wool and make it look better, I won't be welding on spikes because I've already made an half inch thick inner "hot liner" and the wool will only be to insulate it from the outside.
Yes it would be a very expensive drum by the time it got up here! ( guess you live down the West Coast?).
Yes, I have heard of people using those, - though they are normally made of copper aren't they? and probably highly sought after by the copper thieves! - then you are probably talking about the outer casing, trouble is it would be hard to find one which didn't have it's guts ripped out to get at the copper! but you're right, will check that out, if Flettner doesn't find one.
Yes, there are heaps of these little Chinese etc. motors available now and the parts for them are unbelievably cheap - they are extremely lightweight and quite good little motors - but ........I bet Flettner doesn't want to purchase that sort of stuff, whether it comes from India, China or wherever, ( I agree with that philosophy, but I do have a little single 30cc). Can we really fight it?

I have seen a stack of the perforated rubbish bins from town at the recycling station. They are about the right size and who cares about a few holes. Either that of cut a piece of sheet and roll it, even I could get it done in 15 minutes. Probably weld the seam just to keep it smooth so you can lift it off without snagging anything.
Yes a lot of ways to do these things and I might try something like that if I can find one, but you haven't seen my sheetmetal skills and it mght take a tad longer than that! plus I don't have enough S/M but I'll get there........ eventually.
Then again, I did manage to make the collapsible sheetmetal moulds for the refractory part - just lazy I guess.
There you go, a nice fresh roll nearly ready to go in (on) the oven! - folded the edges over to "clasp" each other and added rivets for security. Probably not normal sheetmetal practice but it works.
I think it took a little longer than 15 mins Mike but at least it's on the way.
Got lots of family arriving, staying a week, - more delays.![]()
Played right more free labour
Don't you look at my accountant.
He's the only one I've got.
I've been working from home too long, you are right, these drums 60L are not as plentiful as they once were. I've found a drum to use but it's not a 60L one, I'm not sure what this drum was used for? It has much thicker walls.
I'm getting to grips with this green monster in the corner of my workshop and starting to learn how to use this gear hobb, spur gears only at this stage. Still trying to fathom the calc's for spiral tooth.
I now have cutters for 1 to 3 module in .25 steps, just right for building gearboxes. Seen here is 2.25 Module.
