HWHII Posted March 11, 2013 Share Posted March 11, 2013 Recently I have had a couple of questions from people on my tumbler. So here is mine. I did not make this one. I bought it from a smith who was going out of business. If I had to make another it would be based on this one. The barrel is made out of 1/4" floor or tread plate, and the tread is on the inside. It is also 6 sided so you do not have to put baffles on the inside, which means less maintenance. It will fit 48" pickets and this one turns very fast. Almost to a point it will centrifugal force the parts to the outside, but not quite. I have been told by more than on smith that this the way it should be, because it takes less time to do your parts. Some argue that it should be slow. For me about 20 to 30 min a load. The down side at a higher speed is it will beat up very delicate parts. But even items like small leaves it will do a great job on. It is a must have if you are doing production type work. It also will soften up the edges on your parts.So Let me see yours! Quote Link to comment Share on other sites More sharing options...
Glenn Posted March 11, 2013 Share Posted March 11, 2013 You say 8 sided but I count 6 sides. :) Quote Link to comment Share on other sites More sharing options...

AndrewOC Posted March 12, 2013 Share Posted March 12, 2013 Neat Harold! Could you do us a rough rev per minute estimate, you know, so we may copy this excellent design more accurately ;) Are the bits of steel inside the drum shown in your 3rd photo 'grit' to do the peening? Would you like some pics of propriety tumblers here for comparison? thanks, AndrewOC Quote Link to comment Share on other sites More sharing options...
Whirly Posted March 12, 2013 Share Posted March 12, 2013 Not sure where that came from Glen, have another look at line 3 :P Cool looking machine Harold....ah well, another thing to add to the 'Gotta Make" list.... Quote Link to comment Share on other sites More sharing options...

Yes I would like to see some pics of propriety tumblers from down under. :) Yes the bits are the media. I have saved them out of my ironworker. There are some bigger pieces in there and as I get more slugs from punching I keep pulling the larger pieces out. Ideal for me would be to have all slugs. You use to be able to go to a fab shop and get there slugs for free. Now with the cost of scap steel nobody gives it away any more. Quote Link to comment Share on other sites More sharing options...
Jacques Posted March 13, 2013 Share Posted March 13, 2013 I bought this at an auction last year, and haven't gotten around to repairing it. The motor mount is broken, but it has an adjustable speed gearbox. One thing that is very wrong with it: the door is very small, and I must cut open one whole side and make a decent door so that it is easy to get the stuff out. Price paid was less than scrap value, and I got with it 8 bags full of commercial ceramic media. But I do not at present do much steelwork, so I use the concrete mixer for the occasional batch.

Rockcrusher Posted March 16, 2013 Share Posted March 16, 2013 Here is a tumbler I made out of the head roll of a conveyor and some scrap iron. The access door is pretty small but I seldom tumble large parts. I run around 23 rpm which is slow enough to give good tumble and roll. It only has a 1 hp motor on it with a bunch of mechanical reduction. I have it fully enclosed with insulation board to keep the noise down. I mostly use nickle slag for the abrasive. Here's a pic.

AndrewOC Posted March 19, 2013 Share Posted March 19, 2013 Found the tumbler pics; From "Canning handbook on Electroplating" 14th ed, 1940. There are a dozen more descriptive pages, if some one reminds me of the best way to archive it on iForgeiron. Regs, AndrewOC Quote Link to comment Share on other sites More sharing options...

John Ditt Posted May 24, 2013 Share Posted May 24, 2013 I am developing a large tumbler without welding or machining. The barrell is a black pickle barrel with screw lid. For the liner, I shall use treads of automobile tires that have the inner diameter of the barrel (23 inches). Turned inside out, the treads pop into place inside the barrell. I remove the side walls of the tires with a utility knife. I am hoping that there will low noise. Quote Link to comment Share on other sites More sharing options...
