Compac bore gage clamp important information

boregageclamp83

The square shaped clamp on the 2-6" and 2-12" bore gage models which hold the extensions in place is part #040406 (see drawing item 27). This clamp is sent unfinished, which means it doesn't have an inside thread. The reason is: the thread needs to be custom cut to match the thread already in your gage head.

If you want to do it yourself, you'll need a metric M12x1 tap. Remove the old clamp, put the unfinished clamp in place and using the thread of the bore gage head as a guide, insert the tap, cutting a thread into the clamp. Of course, if you prefer, we can install this for you. 


 

Centering sled

 

A new centering sled is not necessarily easy to install. It looks like it should simply slide into the two holes but chances are that the posts won't be aligned and your sled will jam. Don't force anything and for heaven's sake don't try to bend the posts. They'll snap off. These sleds are custom fit on new gages and that's why you'll run into trouble trying to replace them. If the fit is tight, try a bit of emery and see if that works. Check that there are no burrs. Advance carefully and you'll probably succeed. The other, and better option, is to send it to us for installation
