That reamer will work fine but I think you'll need a 30.6 post if you're using the uber Sachs tubes. 30.9 would take way to much metal out.

Perhaps I had the number wrong...30.6 seems better! I was just browsing on the Quality site while ordering up some other shit and noticed the 30.9's.

I have a bunch of these reams (I think they are called reams, and the cat turning them is actually a reamer atmo...) left over from the 1970s and haven't used them on new frames in decades. They were helpful back in the brass-brazing days but when I transitioned over to silver alloy I began using a light hone rather than trying to reshape or, worse, cut metal from the inside of the already thin-walled seat tube. I have a selection of these (see pic) that I make from offcuts of stainless, slotted, and rolled up with 80 grit aluminum oxide cloth. Chucked into a hand drill, aimed inside the upper 1" or so of interior, and we show the pipe who's boss after maybe a swift 8-10 seconds of rotation. I haven't reamed a seat tube in a very, very long time.

Thanks for the advice...
When building new bikes out of the box, I usually run just a ball hone quickly down the ST as a clean out.
I was thinking more 're-shaping' would be in order for some reason.
The 80 grit will work great.
To be a GRITER rather than a REAMER...any day!

I tig frames, so I do use a reamer, but I made this guy to clean up after reaming and powder. Leaves a perfect finish in seconds.

[prolix21]

with lugs i'd try it without reaming, as e-richie suggested. usually required more when you're doing tig or fillet b/c of the heat distortion

RCP Fabs hone is brilliant. I never thought of making my own so I used a Flex-hone brush, 80 grit

Andy...that's exactly the one I use on the new bikes!
Cape, huh?? We aren't too far apart.
I typically make it down your way for the Ste. Gen road race.
Thanks for chiming in...

Ream is a verb unless you are talking about paper. Both the tool used to ream and the fellow using the tool are reamers.

Hey Luke,
Really like what your doing frame wise and posting your build as u go.
I`m going to be building a Reynolds 731os frame soon and hope i can do the same as yourself.

Being an x machinist i would defiantly use a hone IMO.
Cheers
Alex

Rock on Alex!! I hope you can learn from some of my mistakes and the wisdom of those around us.

Received my seat stay caps yesterday...
time to chop,cut,file,sand,fit.

I wanted something that would remind me of a '57 Chevy hood ornament.
A projectile, of sorts.

Chamfered up some angles and rounded the tips...
I'm going to work on 'sinking' them into the lug with some more backside work too.

P.S. My ten year old daughter asked tonight, "When are you getting more stuff from that one guy...'cuz were lamost out of Twizzlers."

with this all dry-fit, what's your brazing process going to be? disassemble and braze in sub-assemblies?

yes, we are all waiting for the foreplay to be over and see what kind of mess you make of the real thing. Just Kidding, sort of..

[Mike Mcdermid]

This is quite fascinating

Thanks....

Disassemble...
1) Braze derailleur tab, cable tunnel, bottle cage on individual tubes.
2) front triangle (if all goes well)
3) rear triangle (if front goes well)

That's pretty much the method I was taught at UBI, should work out well. At UBI we did step 1 last, although I'm thinking I may do it first on the next frame

This is the process I worked out with Alex Meade and the surface jig I'm having made

1. ST to BB
2. DT to HT
3. DT to BB
4. TT to ST/HT
5. front-tri complete
6. rear dropouts to chainstays
7. braze chainstays to BB
8. braze one seatstay on both ends
9. after checking alignment with a wheel, braze the other end of the last seatstay.
10. rear-tri complete

Sunday.
A day set aside for some serious silver practice.
Perhaps at the end of the day, I'll tackle a few of the braze-ons.

I'm trying a second attempt at a tunnel, before I give up and opting for external housing stops.
(Thanks to some help and atmocouragement)

With positive universal energy flowing...I'll have some pics to post.

Twizzle Twice, Braze Once. :-)

Keep on keeping on man, it's fun to watch.
