ricardo28 Posted February 2, 2015 Share Posted February 2, 2015 If some of you do not know, BiggDawg turned this into a business. I appreciate his work but was short on cash to buy his. I to built my own but, Appreciating all his effort and keeping these posts up after his business venture, I bought a 8in small tumbler drum from him just to kick some cash his way. He has helped thousands on several different forums to get into wet tumbling and figured he deserves a kickback. Link to comment Share on other sites More sharing options...
morpheus Posted February 2, 2015 Share Posted February 2, 2015 can i use a treadmill motor ? is there a parts list available ? Link to comment Share on other sites More sharing options...
biggdawg Posted February 2, 2015 Author Share Posted February 2, 2015 many guys have built them with treadmills but you need to keep all the controls from what i have seen. as far as parts list goes for my tumbler it is on the first and second pages. for a treadmill tumbler i would google it it has been done many times. i just haven't done it.

Heavyopp Posted February 3, 2015 Share Posted February 3, 2015 Treadmill motors run dc voltage -- that's how the speed is varied -- by adjusting the input voltage you can do it but you do need to incorporate the power supply into your build Link to comment Share on other sites More sharing options...

RichJacot Posted January 22, 2016 Share Posted January 22, 2016 I'm hopping someone can double check/help me. I'm building a wet tumbler and I have everything I need except the large pulley. I've used http://www.culvermotor.com/Engineering-Formulas/Pulley-and-RPM-Calculator.htmland I come up with the below. 1725 -- 2 -- 7 = 492.86 492.86 -- 1 -- 6.75 = 73.02 1725 rpm motor with 2" pulley 6" PVC which is 6.75" on the outside of the cap and reducer. 3/4" shaft for one side and 1/2" shaft for the other (because that's what pillow blocks I had on hand). With the heater hose on the 3/4" shaft it's 1" OD (I'd like to drive from the 3/4" shaft). Now to get down to the 70 rpm range it "appears" that I have to use a 7" pulley on the 3/4" shaft. This seems to be much larger than others have been using. Can anyone confirm that I need a 7" pulley or show me the error of my ways? Thanks!

biggdawg Posted January 25, 2016 Author Share Posted January 25, 2016 7" will be close you are running a larger shaft than i run -- i run 5/8 shaft with 6" on it and 1.5 on the motor. for your combo i would run 1.5 and 7" but that is me i have learned you don't have to spin them as fast for them to work.

morpheus Posted May 6, 2016 Share Posted May 6, 2016 http://allentown.craigslist.org/mat/5558851231.html just found these in my area , would one of these be good ? Thanks Link to comment Share on other sites More sharing options...
adam330 Posted May 17, 2016 Share Posted May 17, 2016 I was hoping some one would be able to help me out with the formula for calculating the ratio of ss media to brass to water. I am currently about midway thru my build and will need to know how much media to order. thanks in advance for any and all help. This post has been great.

Steve RA Posted May 17, 2016 Share Posted May 17, 2016 50/50 brass and SS pins by weight. Link to comment Share on other sites More sharing options...
mikeyjones Posted May 17, 2016 Share Posted May 17, 2016 I tumble w/o pins, but I guess I'm odd... Link to comment Share on other sites More sharing options...
bwikel Posted May 17, 2016 Share Posted May 17, 2016 Anything I tumble with primers in gets zero pins. I have used as little as 5 lbs in 40 lbs of brass with good results. 1 to 1 ratio is overkill IMO. Link to comment Share on other sites More sharing options...
adam330 Posted May 19, 2016 Share Posted May 19, 2016 I guess I should have been a little more clear. Lets say my container has a 2 gallon capacity, in order for me to get good results how much of each SS pins, brass and water should I use? Obviously I cant just pack every thing in tight it needs room to "tumble". Thanks again for all the help. Link to comment Share on other sites More sharing options...
bwikel Posted May 19, 2016 Share Posted May 19, 2016 Fill the drum to 75% capacity with brass, cover with water add your detergent,lemi-shine and pins and let it rip. Link to comment Share on other sites More sharing options...
adam330 Posted May 22, 2016 Share Posted May 22, 2016 Ok, last question I promise! what kind of price are you paying for your SS pins? I saw cabelas has 5lb on sale for 24.99 right now. Is this a good price or can I do better? Link to comment Share on other sites More sharing options...
Steve RA Posted May 22, 2016 Share Posted May 22, 2016 Thats a good price, next question is what size are they ?? Link to comment Share on other sites More sharing options...
adam330 Posted May 22, 2016 Share Posted May 22, 2016 They are lyman brand, not sure the exact size Link to comment Share on other sites More sharing options...
Steve RA Posted May 23, 2016 Share Posted May 23, 2016 Any size will work, each has some good and bad points. I like the XL size, most like the medium and some, of course, like the smallest size. Link to comment Share on other sites More sharing options...
trgt Posted May 28, 2016 Share Posted May 28, 2016 (edited) I guess I should have been a little more clear. Lets say my container has a 2 gallon capacity, in order for me to get good results how much of each SS pins, brass and water should I use? Obviously I cant just pack every thing in tight it needs room to "tumble". Thanks again for all the help. I agree with Steve, 50:50 pins:brass is the most efficient in terms of minimum run time for brass that needs to be scrubbed, and then 1/2 to 2/3 full brass/pins vs remainder to top water. You can of course do anything else, it just may require longer run time for results you want, but also highly dependent on condition of brass. I can do once-fired nickel with no pins, soap and water, and it looks new when done. But generally for me, pistol brass, 50:50 brass/pins in an hour so looks great. When I would overload brass vs pins might be double or more the time for same results. BTW, even when I've given a recommendation that works 100% for me, let someone borrow my setup, others had problems, here are some of the variables you'll play with once you are up and running - Hot vs Cold water, hot is better especially dirty rifle brass - Hardness of your water -- if you have hard water, you'll have to play with what works with your soap or even use water softener - How much soap / Lemishine - Pistol brass cleans pretty easily, but rifle brass may need enough soap/hot water to actually clean vs just leaving everything with uniform film of stuff Edited May 28, 2016 by trgt Link to comment Share on other sites More sharing options...
