Mini concrete mixer.
« on: January 24, 2009, 04:02:17 AM »
Got this tumbler in 1972 at an auction sale of a company that did crome plating of nuts and bolts and other small stuff.
I really have no idea of how old it is and the label only has Murry left on it.
The rubber that covered the steel drive shafts cracked and broke off on the last tumbling I did a couple weeks ago. After doing a search on the net and not having any luck finding a parts sourse I dismantled the shafts. Measureing the dia I found they were 5/8" dia. and 14 inches between pillow blocks. 3/4" heater hose has a inside dia. of 5/8".
I bought 2' of the hose since I felt I would just do 6" at the ends of each shaft. For the bump stops at the pillow blocks I used a 1 1/8" hole saw and cut some biskets from a truck tire side wall and drilled the center hole out to 5/8". I soaped the shafts lightly so the bump stops slid on to the far end of the shaft then the hose. Applied some moisture and gorilla glued the bump stop to the hose and a drop to keep the hose in place. I repeated the steps on the near end of the shaft.
Yesteday I placed 500 308 shell cases and 250 7mm08 cases in it with about 15 pounds of rice for the first run after the repair. It worked very nicely so far.

Please excuse the messy loading bench I used it as a repair bench for this project. It is also my work station when wireing and  installing foundation into frames.

Necessity is the mother of invention!!

 GOOD job bringing that puppy back to life!!

Often thought about rice as a media...I didn't think it had the "tooth" to do very good job. How do you find  it working? 
 I tumble to remove sizing lube and lite fouling, maybe this would be a better cost effective way for me to remove that lube. I tumble "Range Brass" (Not my fired brass) but generally my own brass never really gets dirty enough to need full out tumbling.

I bought the tumbler in the spring of 1972. Thumbled about a thousand rounds of 308 brass in corn cob media. Found I didn't like the stuff and the need to dig it out of the cases. did another thousand round of 243 brass and found I disliked corn cob media even more. the owner of the local gun shop, reloading shop turned me on to the rice. I been useing it since about July 1972 and have no desire to change to any thing else unless rice prices goes nuts.
