Does anybody have plans for a thread dial

[bitza500]

Hi all, after seeing 2 homemade thread dials I am wondering if anybody has plans/drawings to make up one as I want to put it on a Model C I am doing a rebuild on
So can anybody help out??????Plus am chasing a tailstock any condition

I made my own but just did a couple of rough sketches from a borrowed genuine Hercus item. Doubt that I still have them but I will look later.
There is a long-running thread on the South Bend forum that might be of help.

I made my 32 tooth gear on the shaper, tooth angle was a bit over 3 degrees IIRC, but a straight cut gear will work OK since there is no real load to drive.

Derek,

I can sort of half help you. Many months ago, I set out to make one based on a genuine Hercus item with cast iron body.

After completing half the drawings from a unit I borrowed, I had the opportunity to purchase my own, and so did. Stopped drawing, as no longer needed.

I can offer you the drawings I have and lend you my thread gauge so you can get all the missing details.

Personally, I would not try to copy the Hercus unit now, it's too difficult for a one off.

Instead I would make the body out of a solid block of aluminium bushed where the dial shaft passes through.

Hi Ken, if I ever get around to seeing you again which will now be after the operation on Thursday YAH

We can do a swap for awhile as that hunk of steel is banging away in my console

And how are you going are you doing much or is it like me all to bloody hard and go and lie on the bed
But the not sleeping gets me as I was up till 3am dismantling my 21 speed/feed gearbox for my mil and things are going from bad to worse the more I dismantle
But I have I hope worked out a basic feed setup as the gearbox also had a driveshaft of the back pulley and connected to the Manual system???

But time will tell as I will be glad to have a new stimulator on Thursday and see how long I am out of action

all the best Derek
