Leadfoot Posted December 22, 2012 Share Posted December 22, 2012 Thanks Schultz.... I now see the collar on them. In some pics it was hard to see them. Thanks Biggdawg....... for the link. I meant to say 6"..... but typed in 8". Link to comment Share on other sites More sharing options...
toothandnail Posted December 22, 2012 Share Posted December 22, 2012 (edited) I built one similar , for tumbling alum parts , using the green triangles for cleaning , however they get wedged into the 1/4" slots in our parts. Causing a lot of cleanup time removing them. My question is , are the SS pins to abrasive for 6061 alum? We use a random orbit sander,120 grit, to get the proper rough surface for our finish to stick to. Any idea if the SS pins may work ? Anybody use SS pins to debur alum.?

Steve RA Posted December 23, 2012 Share Posted December 23, 2012 Don't know, best way to find out is to try a batch. Stop a few times along the way and check to see if any damage. Link to comment Share on other sites More sharing options...
Stormtech Posted December 23, 2012 Share Posted December 23, 2012 I am have trouble finding 8" fittings I did acquire a piece of 8" sdr35 but need a cap reducing couple and a flex cap. I am currently running 6" with nylon bolts in my paddles which are holding up very well. Link to comment Share on other sites More sharing options...

Check with your local sewer utility company - 8" SDR 35 is standard sewer pipe and they should have all the fittings you need. Most will sell you a couple of fittings at cost.

My advise , DON"T go bigger than 8" , the cost difference for caps/ cleanouts is HUGE. A 8" cleanout/cap is about $40-50.00 , a 10" is $247.00 Or you can do as we did and make your own for about $85.00 Link to comment Share on other sites More sharing options...
Leadfoot Posted January 4, 2013 Share Posted January 4, 2013 While I had a bunch of thoughts going through my head about biggdawg`s tumbler design, I was wondering how well dry media would work in these drums? Anyone try it yet? Link to comment Share on other sites More sharing options...
Steve RA Posted January 4, 2013 Share Posted January 4, 2013 Well, before the stainless pin idea came along, people used the Lortones and Thumlers that way. Only problem is that the rotaries are a lot slower than the vibratory ones with the dry media as far as cleaning and polishing. Link to comment Share on other sites More sharing options...

ropsitos Posted January 7, 2013 Share Posted January 7, 2013 So are there issues with running smaller amounts of brass in a larger tumbler? I imagine there is some relationship of brass/media/water/tumbler size that makes things work. I've been looking at making one with a 5 gal home depot bucket, just because the bucket is more readily available than the 6 or 8 inch PVC and fittings. However I'm thinking that it it would be huge over kill for 100-200 .223 cases or 200 .40 pistol cases at a time. Not to mention say 20-60 30-06 cases. I suppose I need to look harder for 6 and 8 inch PVC. thanks Bob Link to comment Share on other sites More sharing options...

ropsitos Posted January 7, 2013 Share Posted January 7, 2013 bigdawg, thanks for the offer, I managed to find the pipe and fittings once I went to a real store (not HD and lowes), I will likely be using a cordless drill or corded drill to drive my drum because they are free to me because of where I work. Do you have the calculations for your reduction? Do you also have an accurate RPM of the drum (or motor current)? From that, and the reduction, I can determine motor RPM and if I can find a motor curve for that motor, I can estimate the load to drive the drum. I can then figure out what reduction I need to use given the drill's motor curve and internal reduction. thanks Bob Link to comment Share on other sites More sharing options...
biggdawg Posted January 7, 2013 Author Share Posted January 7, 2013 I shoot for 60 - 70 rpm drum speed on my drums my motors run 1725 and i use a 1.5 and a 4.5 inch pulleys Link to comment Share on other sites More sharing options...
toothandnail Posted January 18, 2013 Share Posted January 18, 2013 WELL, I tried the SS pins on the 6061 alum tube , WOW! they BEAT it up. It may be a little less aggressive with more pins but not sure if I want to buy another $2-300.00 worth of pins. I got 20# put them in with 3 pieces of tubing filled tumbler FULL of water. ran for just over an hour. I chewed the S%#T out of the tube , good thing it was some that weren't any good to start with.

nanuk Posted February 4, 2013 Share Posted February 4, 2013 toothandnail sees how you are already set up for wet tumbling perhaps you should try other media, such as ceramic, or other blasting media, or even just some slilica sand (borrowed from a golf course) I know our Jackpine sand up here in central Saskatchewan works great for tumbling rusty steel in a cement mixer. stuff comes out nice and clean Link to comment Share on other sites More sharing options...

K5Guy Posted February 26, 2013 Share Posted February 26, 2013 Did you mean that set collars have the set screw? I`ve never seen pillow blocks that have set screws in them to lock in the rollers. Biggdawg, where do you buy your 8" rubber cap? they are 6" caps that i use becaseu i use an 8 to 6 reducer i get them on amazon http://www.amazon.co...ils_o02_s00_i00 bigdawg, I may have screwed up....I ordered 8" sch 40 fittings and the 6" cap doesn't fit the 8 to 6" reducer. It fits inside it. Any sugestions I'd hate to have $60 in fittings go to waste. thanks, K5Guy Link to comment Share on other sites More sharing options...

cworks Posted April 25, 2013 Share Posted April 25, 2013 (edited) Here are a few pictures of my build. It's not quite complete...I still need 2 more bearings and a paint job. quick question...is there a toggle switch that can handle 120 volts? I would like to use a toggle switch instead of a household light switch Edited April 25, 2013 by cworks Link to comment Share on other sites More sharing options...
