Simple conical plugs, on either side of the BB shell, will hold many different BB bores. This is what the HJ jigs use. Others use a plug with a step on the end that engages the shell's ID and results in a shoulder that contacts the shell's faces. In this case a stepped plug would be needed for each BB shell spec. Both conical and stepped plugs usually are mounted on a through shaft. Andy

The piece in the lower left of this picture is what I use for bottom bracket mounting. I only use English threaded bottom brackets(because press fit is crap), so my personal jig has cups that only fit those bottom brackets. For people that want to use multiple types of bottom brackets, I use cones that fit the range of sizes. Both cups are located with set screws, so you can mark a centerline on your bottom bracket and then set the bottom bracket according to the centerline of your jig design.

hello dear all - many many thanks for the reply - great to hear from you.

i am curious about the great images of your jig - dear dsaul - they look impressive. At the moment i am working on the tanner W jig - (shown at instructable - page) and i want to know which part i can improve-
Note i am in the mid ot ironing oout the design - and probably i can enhance some parts - eg. the bottome bracket assembly-part.

perhaps you have ideas - tipps and more!

look forward to hear from you again - best regards
