Hello everyone, I hope you are having a memorable holiday season. Things are going well around here, they are just busy.
The holidays, for me, means some shop time.
I have been spending some time on the new design of the lathe control mechanism.
I made a test lever, awhile back, to see what kind of fit I could get it to be, on the end of the square rod, that runs the length of the apron and has the speed control hand lever. I will most likely make a new one for the final project, but is works for what I need now.
I mounted it in the lathe, with the speed indicator pointer and scale, installed. I then took 5 pictures of the angles of the lathe control lever, when set at, 1) Maximum movement in the 0 rpm direction, 2) Maximum movement in the 3500 rpm direction, 3)Exact location when the pointer is on the minimum rpm setting on the scale, (I think it is about 40 rpm), 4) with the pointer at 3500 rpm on the scale, and the 5th picture has a 12" scale in it, for use of calibrating the image when it is imported into Fusion360.
Here are the Maximum and Minimum pictures for illustration.
I imported the pictures into Fusion360 and drew some construction lines down the center lines of the levers, to reveal all the angles I would need.
The mounting plate (Blue), for the mechanism, will be mounted to the lathe at the yellow line and the lever location is in the pink circle.
These are the construction lines that I derived from the pictures. The lathe lever is in this picture also.
This is where I am at with it now.
I am not near done with it, or is this the final configuration. This will get me the angles of the dangles and an idea of the movement. When done, I will create drawings to take the shop, for the manufacture of the parts.
More to come, and it will all make more sense once the rest of the drawing, with the potentiometer, is done.
