Bicycles Asked on July 27, 2020

i am currently workin on the Bicycle-Frame-Building-Jig that is designed by tanner W at Instructables https://www.instructables.com/id/Bicycle-Frame-Building-Jig/

which bottom bracket assemblies should i work out:

The question is – which bottom bracket-assembly-types would you suggest!?which axles and dummy shells should i drill see https://www.instructables.com/id/Bicycle-Frame-Building-Jig/

well at the moment i am musing bout the extras and features

  • what should i add
  • which features should i add
  • eg some dummy axles for the bottom bracket assembly – what do you suggest!?

i think as long as we can get a standard English bb in both 68 and 73,
we should be fine.

afaik: It’s hard to deal with the press fit sizes because AFAIK nobody is selling facing/reaming tools for them. As far as i know: Paragon has a ton of bb shells available, so we could match what they sell.

but I think the two most standard sizes will probably do for now.

the tanner w fixture is adjustable for width, so we only need one set of blocks see here: https://www.instructables.com/id/Bicycle-Frame-Building-Jig/

and also see the bottom bracket shells: https://www.paragonmachineworks.com/frame-building-parts/bottom-bracket-shells/steel.html

well at the moment i am musing bout the extras – what should i add ?

One Answer

You should use tapered cones, so they work with any BB. There's no need to have different fittings for different BB.
