Re: Eureka!

2023-09-17 Thread cdkr...@gmail.com

Curt, the duplex I made consists of two gears, the small one engages the 
driver gear using 45 teeth.  The larger gear engages the index gear using 
66 teeth.  So the gear ratio through the entire linkage is 1.5 :1  or 2:3  
depending upon how you look at it. I'm using a 90 tooth driver and the 88 
tooth index.  So the chain is 2:1 times 3:4 or 6/4.  Going the other way 
it's 4/6.  You may notice that the gear train is not factory issue because 
of my index mod.  So the duplex gear is "inside out".

I wanted to let the group know that I have a laser engraver that will easily

TMI, I know.  But I was successful in getting these plastic gears to run true 
enough to work on a slightly modified banjo system.  I had to extend the slot 
on the driver side of the main banjo and cut the sides back on that channel so 
it would slide over the driver shaft, not stop against it.  Very minor changes, 
which ultimately expand the banjo to its absolute maximum range.  The right 
side of the banjo is also at it's maximum.  

 

It looks to be the correct ratio, too.  I haven't made any cuts yet, so the 
proof is still in the pudding.  

 

I took a video so you could see it actually in motion.  The scraping sound is 
the plastic gear rubbing against the idler screws, which I had to flatten.

TMI, I know.  But I was successful in getting these plastic gears to run true 
enough to work on a slightly modified banjo system.  I had to extend the slot 
on the driver side of the main banjo and cut the sides back on that channel so 
it would slide over the driver shaft, not stop against it.  Very minor changes, 
which ultimately expand the banjo to its absolute maximum range.  The right 
side of the banjo is also at it's maximum.  

 

It looks to be the correct ratio, too.  I haven't made any cuts yet, so the 
proof is still in the pudding.  

 

I took a video so you could see it actually in motion.  The scraping sound is 
the plastic gear rubbing against the idler screws, which I had to flatten.

Did I mention that I REALLY don't like gurgle stuff? I've found so many
