I am believer of my home made tools.
They are worlds best of course.
My next lathe will probably be a SC4 and I will love to make the nessecary tools already as I have more than enough for my present lathe.I therefore ask if someone will be so kind to measure distance from top of compound slide to lathe centerline(+-.o2 mm) and the distance from cutting point to central holding down stud.On my boxford it is 25.14 mm high and around 60 mm.
How I made the tangential thing in two times two hours can be seen  here.

Niels,
My version of this lathe shows a distance from top of crosslide to spindle centerline is 2.394 inches or 60.808 mm and a distance from top of compound slide to spindle centerline is 0.742 inches or 18.847 mm..  I hope you find this helpful

Cheers,
Phil

Thank You Phil

It is most helpfull as I buy my Crobalt bitts 2.5 inch long and this correspond well with the 60.08 mm and the 18.85 mm is the real important dimension.I will try and make one in less than three hours lathe only.
I hope that You as SC4 owner will test it.

Kind regards

Niels

Hello Phil

Can I ask You to make a picture of Your SC4 like the one here?.
It is needed for determining the distance from cutting point to holding down hole.
Owners of other lathes taking this kind of picture will save me a lot of work on my way to be billionaire.
Benefit for mankind or not?

Kind regards

Niels
