Köping S7C Metal Lathe

[jörgen.ottosson]

Printed gears, looks nice on the pictures, it should probably work as long as you don´t use it frequently (wear resistens is probably less then cast or steal) or run it under heavy load. ( strength is lower than cast/steal ....but that is quite obvious )

Hope to hear how it works out.

Some updates from Finland.

Printed gears has worked fine. Havent milled much, but still some and without any problems.

Leaking, old brass slide-bearings helps (it leaks a bit oil continuously to gears).

Planning to remove that cover and give it to friend whos working on machine workshop.
He can use CNC machine to mill small lip for rubber sealing to prevent oil leaking out,
but still let the brass bearing to get needed oil.

Also I've been looking new toolpost as the now used it totally worn out and beyond repair.
It might be wise to make whole new top part of cross slide so i could use smaller tool holders,
like cheap ones from Ebay.

Hello Tumphu!
I have a Köping S7C from 1934 and the signs on it are worn. See that you posted pictures on these but especially the number plate is difficult to decipher. have you found someone who is better? or have you been able to interpret these?

Hej Eric!
Vad är serienumret på din svarv? Jag har en s7bc nr:1647 som jag försöker åldersbestämma. Mässingsplåten med årtalet saknas.
