dbane883 Posted July 6, 2015 Report Share Posted July 6, 2015 I mentioned once in another thread that installing 8mm tubes can sometimes be a pain. This is especially the case since most are tapping case with the wrong tap. But assuming you have the right M3.9/4.1x0.30mm tap, getting the tube to seat properly can still be challenging. Typically a triangular, square or pentagonal tapered file is used by watchsmiths. For a couple of years, I searched for the right 8mm tube wrench to no avail. But last month I stumbled across a set of installation bits for torquing the tube into place as well as the "reemer" to cut away the inside teeth of the tube. Not easy to find! Normally the bits would fit into specific Rolex tool handles that look like this: As you can imagine, they are not cheap. So here are the results of my homemade handles, which I think will do the same job. Made from left over scraps: Perfect fit. It will be a relief not having to use ghetto files. The innards are scraped away with the broaching bit which is just the right diameter to provide clearance for the crown stalk.: 3 Quote Link to comment Share on other sites More sharing options...
