Then the full assembly of the bike with DuraAce 9000 and off with this bike to the Bristol Bespoke show.
Oh and yes I am taking orders for this frame to answer the questions put to me of late, but only a limited number each year. About ten each year, I have 5 spots left for this year. Some seem keen and this frame is yet to roll down the road!
Ever thought of that rounded insert to be stainless steel? Those areas can get a lot of rubbing from mud/dirt, even when there's ample clearance.
By the way, I may see you in Bristol, and I think you should call this frame "Circus Maximus", just like that chariot racing stadium back in the day.

The trick here is the curved insert is brass brazed which is a higher temp than the silver brazing.
So the brass joint to the curved cut out does not melt when doing the lower temperature silver brazing on the bridge in between the chainstays.
Stainless steel cannot be brass brazed, it must be silver brazed.
I suppose one can use a high temp silver to do the curved piece,(or nickle silver which I detest for various reasons!) then finding .65 mm stainless steel in 31.7 and 35mm diameters for the insert requires a few off cuts of down tube to be about.
Also one would still paint the whole bridge and insert as the cut paint line will have a good chance of corrosion creep under the edge of the paint shoreline as it being being sprayed my water etc. CS bridges have been painted for many decades and I cannot recall any much trouble that I have noticed. So if one wants a stainless chainstay bridge, it is easy to do plain tube without the cutout. The CS bridge with the cutout adds 2-3 hours to the build.

Surely the corrosion is a problem to consider.
I though would be a nice touch to have a s/st part there, but you have very good points there!

Re: I reckon every decent bike should have it
In recent years when I am a bike show with out doubt some one will approach me and I politely listen as they tell me their excitement of how they bought a second hand Llewellyn on ebay and how they got a bargain and how happy they are and the bike or frame is super nice and what can I tell them about it as they supply me the serial number. I am sincerely pleased they are happy and I give them the date it was made and any other info I can recall. I am genuinely flattered that my old work is so coveted.
At the end of the phone chat or the one to one in person conversation I make a habit of saying
"Perhaps soon I will make you your very own new Llewellyn very soon"
after all
it is my chosen path of professional expression
as Gary Larson reminds me

Re: I reckon every decent bike should have it
A 1993 era Llewellyn respray.
I knew the late Chris Mann for some years. We worked in bike shops and trained a lot together, I taught him some bike mechanics , wheel building and how to tie and solder a wheel. I built him 3 or 4 frames over some years. Recently Simon his younger brother wanted Chris's frame refurbished to be his daily ride bike. Joe Cosgrove did a nice respray of the original colour and as I assembled the bike today I thought of some on the training rides we did together. A huge windy day when branches came crashing down around us several times as we climbed up to Montville. It was terrible day to be on a bike, storms, and cold rain for 180kms. But the one that I am fond of is the Magpie at Samford. We had done a hard lap of Mt Glorious one morning and we were at the back of Samford on some quite roads when I suddenly took off ahead of him. He was yelling at me "what the f-ck are you doing, we are done with our efforts.........&#$@!!!*##! you stupid dick head #^%!@**#! " Just then the Magpie started belting him about his head. (this is in the days before helmets) I am nearly falling off my bike with laughter as I look back at this sight. Then he started yelling at me
"you fucking ars-h-le #^%$!!*$#@ you set me up with that bloody efffing magpie!" Oh the fun times. Chris was gone too early. Some times things are just not fair

Dr Brian McLean is experimenting with deeper position so a zero set back seat post is fitted. The seat is fitted 10mm higher than will be ridden, this is to keep it all looking smooth as the bike is on display to avoid scratches. We are off on the big bird tonight

work at the bench this week
Traditionally frame builders would show their style via lug embellishment. In this world of mass production and off shore production for mass consumption I do my best to maintain a blend of contemporary aesthetics with the best of the traditional ways. I very much enjoy this work. It stimulates my chosen path of professional expression. I started on a set of my "Custodian" lugs and completed the down tube lug yesterday morning.

Re: work at the bench this week
Novellara Italy 2000. Main street.
James Victor head Aussie women's road coach (currently U23 head coach)
Me as mechanico (we lived the Euro summer each year, left OZ in April, home in October.)
Alison Wright, good little sprinter and rode in the Aussie track teams as well.
Margarete Hemsley, tough roadie, was on her way to winning the 2002 Commonwealth Games but a slip fall and broken collar bone ended the day when she had the form of her life.
Kym Shirley, good all rounder and could go up the mountains with the best of them. Married to Matt Haymen (this years Paris Roubiax winner)
Liz Tadich, good all rounder and silver at the worlds in 1997.
Janita Feldhan, lives in France now, climb and tough as nails. Olympian that year.
Sara Carrigan, all rounder and quick in a time trial, won the Athens Olympic road race 2004
Hayley Rutherford, good all rounder.
Kristy Scrymgeour, very quick in time trails and twice Aussie champ.
And the Fiat Turbo Diesel 5 speed Manual that never missed a beat.
Crikey we worked hard and James Victor is a coach that cannot be bettered. From 1997 he guided the Aussie team to be a real force. It was a good time to be involved.
