Hey Jon and Crew New issue, speedo seems like it's slow on testing. See below
I re-stickered the left side 4 gauges and they look good, hopefully last ok
Using a hand drill I drilled out the cross arm brass bushing 1/16" easily, then I assembled it all and I re-soldered the pin on the speedo and that went well overall. I used a small pin with cap that Jon sent me (thank you !!), and soldered it together using just a dab of solder. It feels strong Prior to solder, I put the pin/cross arm together and then soldered. But it seemed to have some resistance to spinning comfortable. I got a very fine file and filed the solder off at the top of the sleeve at the repair.
With the speedo tranny end in my drill, I spin it and the speedo needle moves smoothly but max speed is only 26 mph as the drill is spinning 2500 RPM. I know a lot of cars have a top gear of 1:1 ratio, so that might mean 2500 rpm at the engine. But the odometer is spinning very fast, like i'm going 80 mph fast.
LMK your thoughts about why this is. Could be friction at the top brass bushing (I drilled and then filed the brass pin, maybe no smooth?), Or is there a problem with the drive at the btm. Not 100% clear how the spinning mechanism-driven by the square speedo drive, under the brass cup drives it, but there maybe an issue there. Or is there no problem and 2500 RPM should be 26 MPH and I've bumped my head and I'm overthinking it.
Any thoughts Stovebolt world? You all are helping me tons. !!
