we all know my latest project and this tool is custom-made for that. While this tool is specifically for that project and accomplishes nothing else it serves 2 distinctly different purposes related to the current project.

This pic is side "A" while the next pic will be side "B" (flip-side of the same part) tho neither is more/less important than the other and both are required to accomplish 2 specific, tho unrelated tasks. Neither side is used more often than the other. Both sides are used on every Pro-Mount made. Tho admittedly I made 6 of these tools to speed up production.

My guess is someone "may" guess one side correctly, but that no one will get "both sides" right!

bearing press and mount saver press?

tho more aptly its the mount "stop" than a bearing press tool but close enough. The stepped side is a matched internal configuration to the Boge mount internals that centers itself within the mount and bottoms against the mount floor. Its a snug, self-centering slip-fit that prevents the mount from collapsing while pressing the new spherical bearings from the opposite side of the mount when in place.

Pic shows tool in place. Red arrow indicates travel of press used to seat spherical bearing. Yellow lines indicate how tool stops mount from compressing under pressure from arbor press by introducing a "fixed/solid" base for the mount floor inside the OEM mount.

But what does the other side do?

BTW mount-savers are a simple hand-fit that require no tools other than opposable thumbs. Even a chimp could do it ;-)

Merkin

taper for boring the mount to fit spherical bearings?

VAP

to accomodate existing mount bearing "press-fit" bores. Mount thru-bores were bored larger then tapered from the top to accomodate the spherical ***** orbital movement up inside the mount but no machining to accomodate spherical race OD's were done.

Merkin

the center bore of the tool and mount looks mighty close

Taper bore's ID is actually .1275"/3.238mm larger than mount bore. But it is close and for a reason.

This pic shows the taper bore pressed into a Boge mount, ready to perform its task and shows why it is needed. Its up to you to figure out the "need."

btw, very impressive work senor!

until after I machine them. The bores run between .024"-.085" eccentric (off-center) to the ,mount-bodies and have to be made concentric with the mount housings long before this tool is brought out to serve its design purpose. This tool is used 48-72 hours before the spherical bearing can be pressed into the mount but after "all" maching has been completed.

BTW here's a pic of every CNC mill, lathe, press, die grinding or machine tool involved in making even a single Pro-Mount. Some of these parts consist of 6-12 of each but only one is shown to prevent redundancy. There's not a single tool in this pic that doesnt come into direct contact with EVERY Pro-Mount produced via holding, measuring, centering, machining or testing the Pro-Mounts or one or more of their component parts before, during or after production.
