Hi all,
I'm seeking advice about which BB machining tools to buy for my
personal use (I'm pretty much planning on dealing with lots of bikes
forever so it's plenty worth it to me). I currently have need of
piloted english taps, so I'll be getting either the Park BTS-1
tap/facer combo tool or the VAR piloted tapset, which doesn't have the
facer and is close to the same price. The VAR is attractive because you
can still get french and swiss taps for it - not super relevant, and it
would be pretty expensive to actually buy those taps, but I have little
doubt that it could be worth it to me at some point, so that's the
piloted tap I'd get over any of the other ones if I was going to get
just a piloted tap set - but whether I'd ever actually get those taps
is questionable.
I've never used any BB facer (and have only used the VAR taps). One of
the big questions I'm looking for opinions on are the drawbacks of the
BTS-1 as a facer compared to all the others, since the BTS-1 uses hand
force rather than a spring to push the cutter against the shell. I
haven't been able to find much about this on the web; Park's
description implies that the main drawback is that it's hard or
impractical to cut especially hard materials with the BTS-1. Would this
only apply to ti, or would some steel shells have issues as well? What
about for operators that don't have a lot of upper body strength? Is
difficulty or inaccuracy in trying to apply consistent force an issue
on either hard or soft materials? If you needed to prep lots of nice
frames all the time, would the BTS-1 alone work well and/or save time,
or are there drawbacks to it where you'd want to use a seperate tap and
facer to do the best job possible?
If I get a seperate tap set and facer, which facer should it be? I'm in
the US so if the Park is as good as anything, that's what I'd get for
the greater replacement part availability.
Finally, what actually is involved in making these taps, and how
feasible would it be to get some made for the Park or any other set?
What tools would be necessary to make them?Note these wouldn't ever
need to be used very much. Thanks
