HI Guys,
Run into a small problem on my Colchester Mk 2 flat head.
Cross slide felt very stiff and was difficult to crank. Assumed a stray chip must have gotten stuck on the screw. Stripped it all down and gave it a good cleaning including the gibs and the cross slide screws. There was some gunk and pieces of chips/ swarf in the gallery of the saddle casting where the cross slide screw goes. Looks like at one time there was some grease on the cross slide screw
Anyway put it all back together this evening and thought it was ok, after some fiddling of the gib and cross slide nut screws, until I bolted on the QCTP. It was very hard to crank the cross slide. Loosened all the gib and cross slide screws.
Is there a particular way this assy goes back together?
Any preloads on the gibs # 8167 & #8475 gib adjusting screws. I tightened these before attaching the Xslide screw till i could move the xslide freely but didn't feel tight as i pushed and pulled it across the saddle casting.
What is the rule of thumb for setting the tension on the cross slide nuts #8278 & #8513/8630?
Maybe I have something out of alignment? On disassembly of the xslide screw, I did not see what direction the rear cross slide nut # 8278 was facing. I put the semi polished #8630 anti back lash wedge side towards the operator.
Appreciate your help.
Greg
