1 = motor pulley = 1.5"
2 = Jack shaft pulley = 10"
#3 from the jackshaft to #4 on the drive shaft will equal 85rpms with a 4" tube.
#3 = 3.5"
#4 = 2"
If you switch the pulleys on the jack shaft from #4 smaller to #3 larger on the drive shaft the speed would be around 40/50rpms for square / rectangular bottles with a 4" tube.
Hope this helps and isn't confusing. Good luck with your project. Paul
thanx for the input folks. I ran out to a U-PULL IT junkyard today and got 4 different sized pulleys ($2.00). my motor is also 1725 rpm w/ a 2" pulley. Hopefully i'll be able to vary the pulley size to adjust speed. I'll post some more photos as I go along. Thanx again !!!
this is one i took the tire off. looks like about the right size??? need to figure out how to attach pulley wheel to drive roller. getting there...............
Hello Lobey, wish I could help you out with your flask but I'm not setup to do any grinding right now. I was out of this for about 5 years and just got back in. I don't normally clean for others as I have enough of my own to clean up but if I had the setup to grind I would help you just to help this time. Strap side flasks are usually pretty sturdy.
To grind you need copper that you can just use for that purpose. I use a 12micron aluminum oxide for 6 hours and the glass comes out looking like a frosted bottle, and most scratches are gone. Kind of cool. Not a good idea to mix cutting copper and polishing copper. Anyway, a friend is going to hook me up with some used/worn out copper at the Grandville Mich show next month that I can use for that purpose.
I haven't given up gang........... i decided to order pillow blocks and pulleys from a distributor. I'm saving quite a bit of cash by building it myself, and this seems like a good time to spend wisely. Next wednesday is disability check day, will order stuff after that. Items not nearly as expensive as i would have thought. Ok, take care all..............
Wish we lived closer to each other Jim. I get a discount through my work on parts like you are getting for your tumbler. For the pillow blocks, are you getting the kind with the grease fittings on them? They last forever if you keep them greased every couple of weeks.
If you are buying v belts, try a link type belt. They might be a little costlier but it really cuts down on noise and runs more true than the classic v-belts.
I was skeptical until I tuned up my table saw and that was the recommendation to go to a link belt. It made a believer out of me and you will always have the right size because you make it smaller or larger by pulling out a link or adding one.
Let me know if I can help you with anything. Good luck with your project. Paul
