Good evening.
And the flat belt returns another time...to annoy innocent machinists and enginemen. Ive recently run into some intresting stuff.
Lets begin with our old camelback ...I need it...because our 1950s work shop drill press won't do what i need, it would chatter itself to hell, got the horsepowers but aint got the beef. (Holes in steel...larger than 1 " ) And the camelback shure as hell goes slower and has a lot more beef. But the boss says...the belts will slip. I say: "something is wrong with the belts. That machine aint have tons of beef because the engineers thought it would only run 3/4" drills...."
I have not tried this yet, its not urgent at all, but at some point in the next 1-2 month i would like to get this crap drilled.....
And in case our boss actually is NOT being paranoid about slippage....i think he just forgot to use the belt grip wax.... i will have to fix this mess....
Now i have just been sawing up a load of firewood with our deutz diesel and a big old circular saw and the fact that this tiny pulley on the saw can slow down a friggin 8 hp diesel quite a bit (may be 6 or 10 hp, not shure, i am bad at remembering numbers, can only store facts in my head) demonstrates that most likely the episode with the camelback is just some stupid misunderstanding or a case of insufficient tension, waxing etc.
However....I am currently working on a rather big model of a lineshaft system, have a look for yourself :
And I want to use as much flat belting as possible. Some will be round rubber belting, for large distance low power stuff, and short belts countershaft to woodlathe etc. will be small V-belts, they make em down to 1/4 " and even one step smaller (5mm).
I have some leather material about 7/8 " wide and i have been fiddling around with it today, like wrapping it around the spindle of our small drillpress to see if i get traction......minimal...bad...pretty much no traction unless i pull at the belt with ridiculous force.
Now i have not yet used the wax because i did not find the stick today...but still. Old crappy belts always work to a certain degree. But this new material just wont do anything......
How do i approach this, the leather is not yet spliced so now would be the time to do any surface conditioning etc....

P.S. Please enlighten me about selpentine belts. I looked it up and they also sell as poly-V ? We call those " ridged vee belts" to give ya a litteral translation of the German word "Keilrippenriemen" . But they have vees, how is that gonna end up working on a flat pulley ?
