If you're using a crank that uses external bearing cups, such as some of 
the Silver cranks that Rivendell now sell, it's important to have the L and 
R threads and faces of the BB shell perfectly aligned. And you might be 
surprised at how much a BB shell that comes from the factory with perfectly 
aligned threads and faces will be distorted during framebuilding, with all 
the heat going into slightly over half of the diameter of the shell. I've 
had custom frames from well-regarded framebuilders that have needed quite 
extensive chasing/facing to get the BB threads and faces back to alignment.

I thought it slightly ironic that the best prepped and aligned frame that 
I've purchased in the last quarter of a century or so was an off-the-shelf 
Mason aluminium frame that I bought last year. The BB threads and faces had 
been machined post welding and painting, as had the headtube facing, and 
all the threaded fittings on the frame for mudguards, racks, etc, had been 
cleaned and greased as well. I also think it's just about the nicest-riding 
frame I've ever ridden.

Cyclus BB threading tools from Europe are sold at various Euro retailers 
and of reliable quality and depending on where purchased from say $85 and 
on up. They make at three different versions, all with handles. With 
cartridge BB's however, having the two sides perfectly aligned isn't 
critical as it is with cups and cones. In fact it has no bearing on it's 
function, pardon the pun. So for straightening/cleaning out threads the 
Hozan or home made tools without handles do just fine. We're not referring

Thanks Eric L, everything else came off the bike easily, so go figure. 
Making progress slowly.

Thank you Rob and Nick, my homemade tools are ok for now, but I should 
really get a quality tool next time I have this problem.

Hozan make both piloted and non-piloted BB taps (part numbers C-405 and 
C-402 respectively). The piloted taps are far superior, as they ensure that 
the left and right BB threads are co-axial and square to each other.

You can find pretty cheap piloted taps for chasing BB threads on Aliexpress 
(eg https://www.aliexpress.us/item/3256803775069380.html). Probably OK for 
home use, but I have no idea of the quality.

Re: [RBW] Hozan Bottom Bracket Tapping Tool

[robert morrow]

Hey John, I have used the Park BB facing and tapping tool numerous times as a 
mechanic in High School and college a million years ago as well as recently. It 
is a great tool. Follow the directions and you will get square faces and clean 
threads every time. Unfortunately, it is crazy expensive, I think like $600. or 
so. I have owned 6 Riv bikes and, while I love both their esthetic and the 
ride, clean threads are not Riv's strong suit at all...a small, out of 
character and annoying lack of attention to detail, especially at their price 
point. I have used it in your situation as well. I had gotten an old Bob 
Jackson frame which had BB threads crossthreaded. Park tool worked great. Good 
tools matter and good tools are expensive. For a one-time issue, I would seek 
out a good LBS (talking like old time pro shop, NOT Bike Doctor...Blenky in 
Philly comes to mind) for this task.
All that said, while most of my tools are Park because they're old, I have some 
Pedro and Hozan pieces that work fine. But you can't beat Park tool for a tool 
requiring the kind of precision you want for this task. FWIW

Rich, thank you for the offer, but I'm in eastern PA, so a road trip to 
mid-Iowa isn't in the cards.

Garth, thank you for the u2-video, that was very informative. I've got some 
extra BB cups that I can sacrifice to become tools, so I'll give that a try 
with a lot of caution.

Eric, I'll probably go with the Hozan tools if the home made version doesn't 
work out.

Thank you Jeff. I'm using Groit's Garage paint cleaning clay to pull the 
dirt/grim out of the paint, I'm about 1/2 way through that process, need to 
spend some time at the BB. Then it will be a polish to smooth out small 
scratches followed by one or two coats of wax. Should look like the steerer 
tube's paint when I'm done. Some chips but not bad for being 41 years old. 
Also need to do a frame saver treatment before building it up.

George, no the cartridge BB was from another bike, bearings have a lot of 
play so I was only using it to figure out spindle lengths. Always fun 
trying to get the shortest spindle to work with a frame and crank to 
achieve a low Q factor. The bike came with a full Dura-Ace groupo from '92, 
including the BB which I'll try to reuse. Unfortunately the crank and cogs 
are too high of a gearing for me. I'll need to use my favorite of 46/34 
chainrings and 11/34 cassette so I can climb the hills in my area.

If that BB cartridge shown at the bottom of your photo is what came out of 
the Sequoia it almost looks like someone used some kind of tar or roofing 
caulk to lock the BB in place.  Bad idea.  I'm glad you were able clear up 
the threads pretty easily.

Re: [RBW] Hozan Bottom Bracket Tapping Tool

[Bill Lindsay]

I would think that if you brought a frame to a shop with the right tool, 
that shop should be able to chase your fixed cup in under 15 minutes.  At 
$2 a minute, that should be $30 or less.  I can't imagine that you could 
make a suitable home made tool for under $30 of headache.  There's got to 
be a good shop in the eastern half of PA.  

I'd love to have a set of quality BB chasing (and facing) tools in my 
possession, but haven't pulled the trigger on the expense.  For work of 
that type, I pay Mike Varley, which is a 80-minute drive, but it's always 
worth the trip.

Re: [RBW] Hozan Bottom Bracket Tapping Tool

[Jeffrey Arita]

JohnS: Sorry, late to the party: yes, I've got a set of the Hozan's you 
mention.  They've worked well in many BB shells (I've caught and released a 
fair number of frames).  Yes, they aren't cheap but they do the job.  I was 
advised to use Tap Magic PROTAP cutting fluid whenever using taps/dies by 
folks on the iBobs.

I've found some BB shells to be ever so slightly undersized, while others 
simply have some grease/crap/corrosion in the threads.  Just 3 days ago I 
bought an old Trek Multitrack bike (I think '96 MUSA frameset).  Tore it 
down and it became obvious the owner kept it housed in a garage.  
Everything removed easily and the BB shell was pristine (quite unusual).  
Chasing the threads I could simply turn the Hozan taps *by hand* (I 
normally have to use a pretty big adjustable wrench).  YMMV.

I normally start at the BB shell and then work around all the other 
threaded bits on the frame and fork (M5s for braze-ons, M6's for cantilever 
studs, M10 on the derailleur hanger).  Generally makes reassembly 
straightforward and drama-free (boring).

Good luck,

Jeff

Re: [RBW] Hozan Bottom Bracket Tapping Tool

[JohnS]

Rich, thank you for the offer, but I'm in eastern PA, so a road trip to 
mid-Iowa isn't in the cards.

Garth, thank you for the u2-video, that was very informative. I've got some 
extra BB cups that I can sacrifice to become tools, so I'll give that a try 
with a lot of caution.

Eric, I'll probably go with the Hozan tools if the home made version 
doesn't work out.

No experience with the taps, but in my experience I would pick a Hozan tool
over a Park. Park tools just seem so-so to me.
