colchester lathe spares

after a slight incident involving a large student 1800 a forklift and gravity i require another cross slide keep and pinion shaft. tryed colchester but they havnt got back to me after a week.
found another place - nobilla machine tools who have what i need but the prices are near what i payed for the machine

anyone know of any places that i could mail or phone? dont expect it to be pennys but £200 for a 4 inch shaft and casting asked about a new screw and nut £400 think ill just keep adjusting it till theres no more threads

try GandMtools in ashington, they have a website.
What's it your after?
Lathe spares, are really expensive.

heres a picture sent by the helpfull chap at nobilla

im after the assembly 2nd fron the left, keep and pinion shaft. dial bearings and gears are all fine, keep castings too fidly to weld unfortunatly

looking into how acme threads are cut to see if i can make my own nuts and screw

emailed gandmtools to see what they say

"(looking into how acme threads are cut to see if i can make my own nuts and screw)"

1 - Buy the corect acme tap (probably LH 2start).
2 - Screwcut nut first leaving a few thou to finish with the tap. (do 2 just in case)
3 - Cut leedscrew using nut as the size gauge.
Remember bottom clearance is quite large on acme.

PS. When cutting multistart threads,
jot ALL your numbers down + put different colour paint blobs on the thread indicator so you always go in @ the same point.

good luck
