Somewhere on the forum there is a thread about making the barrels roll faster. Somebody said if you put duct tape around the rolling shaft it will make the barrel go ?faster? or ?slower?
I can't find the thread now and want to make the barrel on my 3# Chicago Electric go faster if I can. It rolls slower than my QT66 and my 33B.

Thanks John. Barbara and I talked about that thread but couldn't remember if the duct tape thing made it go faster or slower!
I'll try it and see if I can speed this one up bit.

Hey Llana, the thing to remember is that it's directly proportional. In other words, if the driven shaft gets 10% bigger, the barrel will turn 10% faster. Because of the small diameter of the driven shaft, small changes such as duct tape can have a significant impact. Besides, it's easy to take it off and be back to the orginal with just a quick rip! So go ahead, put 'er in overdrive and see what happens. ;D At the risk of sounding like a teacher, I probably should point out a few other things just so that you'll be aware if problems develop. Changing the speed of the barrel by altering the reduction ratio from the motor also inversely affects the power available. Increasing the speed of the barrel by increasing the diameter of the driven shaft is the same as putting your car in overdrive. You can go faster, but you don't have much power to get moving from a stop. Therefore, it's a good idea to place your barrel on the base with the motor already running. Starting a load from a dead stop is the hardest thing that will shorten the life of your motor and starting in overdrive will only make that condition worse, so always get a running start. Sorry to get so long winded and I tried to avoid getting too technical, but I only want to help you all get the most from your equipment with the least amount of headaches. Besides, I've been gone for a while and now I've got all of this pent up typing urge to get out of my system! Ron

Hey Ron, said welcome back on another thread, but in case you didn't see it - Welcome back! We have all missed you! I put two wraps of duct tape around the shaft - it doesn't look like it's going any faster though. May add another couple of wraps. I always have the motor going before I put the barrel on. Learned that when I first got on the forum and might be why this little Chicago Electric 3#r is still going. I really expected it to have bitten the dust by now - rolling 24/7 for 4 months. Course, speeding it up might kill it.

Had to say - that after reading this today I decided to get speed greedy and wrapped a load of really thick wallpaper (blown vinyl) round the drive shaft. Put waaay too much on, and my 6LB tumbler could only just manage to turn about a 1lb of tiger eye in polish - probably even less than a 1lb. Anyway - it went round so fast I couldnt hear anything - I reckon everything just stuck to the sides. I took the paper off after a hard time trying to get the tape off which Id spent ages wrapping tidily round it. I new the outcome before I started - just wanted to see it in motion. Back at normal speed again now. andy.

i, too, have a #3 Chicago Electric, when mine looked a bit "slow" it was because the belt had deformed and needed to be changed. i've gone through about 6 belts in almost 4 batches of rock. i am tempted to get a back up machine.
addicted to grit, i am.
