hi, im hoping someone can explain the mechanism for adjusting the jib strip ci the head of the above bench mill..

the x and y axis slides are the conventional slide adjustment on their dovetails, but the head jib strip has a screw at the bottom which appears to be for limiting its depth at where the jib strip sits , and a screw at the top which has a machined collar that locates in a cut out on the jib strip… I can not see how those screws alter jib strip clearance..

thanks in advance for any help..

It is a tapered gib so a bit like a wedge that will tighten the further in it goes

Loosen the bottom one and use the top one to move the tapered gib in and out, when happy with fit nip the bottom one back up. You may have to do this a couple of times as the locking can slightly affect the adjustment.

thanks for that Jason… that makes sense … its in bits so that I can transport it to an upstairs workshop but ill have a play along the lines you suggest and see how it goes..
