1943 M-head Upgrades

Because I'm a nerd...
Original motor was a 1200 RPM motor. So I knew the step speeds on that motor setup. So I created a simple spreadsheet that would convert that into my mechanical ratios. Then with the new 1800 rpm motor, I was able to calculate my 1:1 speed with the baseline 60Hz frequency on the phase inverter. From there, I took 5 hz steps from 70 down to 20 and calculated speed points, sent the chart to the UPS store and they printed and laminated it for $4.52. Voila, speed chart for each step pulley at each frequency. This will suffice until I figure out how to install my tachometer.

Looking good -- you are clever at figuring things out! Keep it up and you will have a serviceable machine with a nice vintage to it

Also --- Looks like a Gorton Rotary Table down there....20" whopper! ????

Thanks! Its a hobby and I am tenacious so I enjoy figuring this stuff out.

The table is a Troyke 18" diameter. I bought it for really cheap locally and its in really good shape. Its pretty much too big for the bridgeport but will be used for machining out wheel centers from hub centric to lug centric bore diameters and stuff like that.

Machine is doing good work so far!

Rolled out another one. This is a 29 spline Isuzu yoke adapted to a 23 Spline Jeep Dana 300 transfer case to make the case a divorced setup with a floating mid-ship shaft. I play with trucks; this is for a friend's project.
