    Revisiting weird gib issue

    I use a brayer on the surface plate but that doesn’t work on dovetails

    Revisiting weird gib issue

    That’s exactly what I use on the surface plate, at some point I will do that with dovetails as the master reference as you suggested. I need to make something to spread the Prussian blue evenly though…I tried with a brush and it was a huge mess

    Revisiting weird gib issue

    I’ll take some pictures and share here…to your point maybe the issue is the measurement

    Revisiting weird gib issue

    Agree, but the only issue I care about the cross slide rocking despite having the gib inserted…the gib rocking up and down was simply a theory correlating a potentially badly fitted gib to the main issue Absolutely correct, that’s what I have the sides are parallel height-wise but tapered...

    Revisiting weird gib issue

    Yes will do and I agree, if things appear flat on the gib side but the issue persists then I can go through the methodical testing, I have a feeling it will be resolved since the ground tapered gib blank removes the slop across the entire range of travel(tested by inserting and removing the gib...

    Revisiting weird gib issue

    Makes sense to me but since it’s a brand new machine I do have the option of getting Precision Matthews to do something about it…I just need to be able to prove it to them…they sent me the replacement gib as their suggestion to fix the issue but I didn’t want to fit and cut a new gib without...

    Revisiting weird gib issue

    @Susquatch @Mcgyver given what I said above about the blueing pattern I was getting on the sliding gib surface, I see clusters of high spots on either end of the gib with the high spots on the thicker end (the one that had the up and down play) towards the centre of the gib vertically, ie the...

    Revisiting weird gib issue

    I totally agree but as mentioned above I don’t have a good way of measuring the ways…I really wish I did. Been looking all over for a piece of cast iron or a reasonably priced camel back kit to make a triangular straight edge with no luck. I’ve also been eyeing a 150-300mm interchangeable mic...

    Revisiting weird gib issue

    Very valuable info, thanks for taking the time to explain the various tests. If had a straight edge and a micrometer large enough I would have definitely started with testing the ways before messing around with the gib, however I don’t. Since I measured the slop to be consistent along the Y...

    Revisiting weird gib issue

    Yes that’s exactly how I was measuring. I insert the gib with both adjustment screws removed and I sung the gib in and pull saddle just a little to wedge the gib in place. I’ll try your way as well where I won’t use the adjustment screws but only tighten the locking screw I don’t really care...
