9 forum posts 2 photos | I acquired a 7/8 Fobco drill press today along with Jones and Shipman 540surface grinder . The drill press is a non runner. I’m hoping it’s an easy fix. But I noticed the quill does not return had quick look and no return spring. Lathes .co.uk do the spring so no problem there but the housing just spins does anyone have a drawing of this assembly or a manual please. I am also looking for a manual and any useful info on the surface grinder. Many thanks in advance Mark. |

859 forum posts 268 photos | ..on a couple of other (but similar) drills I've owned the drum is rotated to adjust the tension and then locked by a square-headed screw in the head casting which bears on the drum spigot.. ..could it be underneath, pointing up..?

![]() 1174 forum posts 303 photos | The spring housing has a small ball bearing with a quite powerful spring pushing on the housing so you can only turn it towards making the return action stronger theres a small hole nearby that you can poke a small rod into to release the ball..

The hole near the front has a spring in it with the ball the hole behind lets you release the ball Thanks for the reply I’m assuming that your picture is of a Fobco Star !? There is a one hole underneath that feels like it has a ball bearing in it. It does release the drum to spin both ways if I insert a screwdriver. I have now found out that the contractor inside has a burnt out coil. So I’m trying to source one the will fit inside the machine. Thank you to everyone else who replied. mark |

![]() 1174 forum posts 303 photos | Yes as i said it only allows you to tighten the spring return action if you want to loosen it you push the ball off the housing and it will loosen it |
