Very much the sculptor carving away the marble to reveal the figure within.

Also I am beyond taken with that socketed seat tube lug. Filing that away for future build reference...

Thanks.
The socket seat stay seat lug is not a new idea,or my idea, it has been done before for at least 30 years. I have used them 20 years ago with OS tube sizes and 14mm seat stays.
My blend of those lugs from years ago with today's bigger tube sizes and what I desire for my own production here.

What is happening with the rear dropouts, the threaded tabs been cut off?
(sorry if I've missed it)

My dropouts have the M5 eyelets cast in. For road bikes that do not need the eyelets one cuts them off. The shape and blend are filed in after the chainstays are brazed to the dropouts. It is too cosly for me to have new tools made for drops without eyelets so these drops can with or without eyelets via the hacksaw and 10 minutes with the file

Those dropouts are good lookers indeed.
You've inspired me to cut a set today.
Thanks !

Work on the dropouts continues on a Monday



Die grinder, files then the sanding begins



120, 320, 800 and finally 1500 grit under balsa wood sticks. Sanding is the time consuming part of the process and it gives one plenty of time for contemplation about the world whilst listening to the radio




Polishing takes a few minutes and reveals if the sanding is done correctly



Wayne's fork blades are ready for the crown

[Dazza]

Filing the rear dropouts



vrmmmmmmmmmmmmmmmm (technical for a buff in a die grinder)







Gremlins

Working away, listening to Radio National via The Australian Broadcasting Corporation.

[Dazza]

Tubes and lugs forming up. Die grinder, a bit of time and care and more die grinder, till the fits are eased till all is snug and stress free

[Dazza]

Marking out
The head tube is going to get some Llewellyn treatment, I am using a Moore and Wright dividers I got from High School metal work in 1978. Still going strong.





The crew get to work
dodgy looking sods doing parole work ?

[Dazza]

Llewellyn Custom Bicycles head logo is cut by light amplification by stimulated emission of radiation. I then get the Jeweler's files out and dress it up and then press to fit snug to the head tube







Cooked up and still hot

[Dazza]

whrrrrrrrrrrrrr, file file file, repeat four times

[Dazza]

Cook up the suit

[Dazza]

I got this file in 1987
Lovely lathe file and still used just about every day. The steel was a good brew back then.









Seat tube to top tube vent

[Dazza]

Stainless steel, delicate shorelines requires a lot more time and care in preparation for the cook up.



Fork work and cook up while listening to Warner score and score and score

[Dazza]

Whoops, dropped it, lost for ever. Get another one, file file , dropped, curse, $#@&@!!!*&!##. Lost two for ever. Then I got two brazed on.

[Dazza]

Single point turning the crown race seat to 30.02mm is the only way to go with a stainless steel fork crown. Have I said lately that a lathe is " a beautiful thing" ?

[Dazza]

spot on for the crown race fit



Careful filing of the surface is the first step. New and sharp file are a must for this.



120 then 320 grit



1500 grit under the balsa wood sticks. The sanding takes the time, if done well the polish will be quick and reveal the Lucentezza.

Working up the Lucentezza
