My last post had huge verbage content, so will use this separate post
to say: It's nice to see others joining in and showing their work.

Well I will start of modestly I think with my front mech and a dremel. It is a FD-1056 braze on and weighs 99g. Th clamp is pretty bulky too. Also for th rear mech set srews are easy to find in aluminum but where can I find the M10 mount bolt. I currently have a RD-6600 rear mech that I want to loose weight from. Fibre lyte can supply the cage and pulley wheels and I might take the dremel to it.

Other area to loose weight from are the d/t shifters. I am struggling to find alloy mounting bolts of the right type. Any ideas A dremel can loose weight from the levers themselves preety easily. I might get a local enginerring firm to make some some alloy parts for these.

However where can I get a Ti 1" locknut for threaded steerr. The bike I am loosing weight on uses a threaded steerer and I am not changing it.

Ther is crtainly inspiration and Wally the rear mech you have done is certainly very impressive bit of engineering you have posted so far. If only more us had access to the machine tooling you have.

The funny thing is that I'm not a machinist.
Had an interest in making things, so took machine shop in high school.
Ironically working on go-karts mostly. But I was a runner back then.
Gravitated to cycling later and would never think of building go-karts today.
Too noisy. Was an apprentice after high school for a short gig. Didn't work out
so did most of my working life assembling Western Star trucks, another irony.
Conflict between bikes/trucks, you get the idea. But when my interest in
lightweight bikes really took hold, I saw the need to get my own equipment
although much larger than what you see in the pics in my present shop.
Had to downscale that because of family economics.Eventually I saw the need to start up another shop. I had lots of ideas some that I sat on for more than 10 yrs, till I got around
to bringing them to fruition. There were so many things I wanted to do, that were so involved, I could see that I wasn't going to be able to pay to get it done. There was a long list of other projects, as well as time to develop the skills needed to acomplish some of the projects. When Freightliner bought Western Star and eventually took our jobs to Portland, OR. ironically it was the skills that I developed working in my home shop that helped me land/cope with the job I have today.
Basically working as a machinist, at a place where we make radios/communication equipment for helicopters. Machinery doesn't have to be huge or expensive. It certainly costs more
than a dremel. But there is so much machines/tooling coming from China/Taiwan
these days, that it is much less expensive than say 20 yrs. ago.
My machine cost only 1300.00 in 95. I've don many mods to it to be more versatile
and efficient, and have more mods on the way. Some of them only because I've got to the point of: Just because I can. So It doesn't cost tons of money. You can buy a 7x12"
mini lathe for 4-600.00 these days and a small mill for 5-700.00.
Tooling can add up. But if you're careful and don't let that side of the cycling/lightweight
bike building take over. A lot can be accomplished for a very little.
I once had a Stereo salesman in one of the most Expensive audio boutiques in
Vancouver,BC see my Colnago cycling jacket, so we started a conversation about
bikes. He a MTB'er and me a Roadie. I told him about some of the projects I was working on
and he swore that you had to use CNC to accomplish them. I was only planning on a
bike that weighed 10-11 lbs then, not the 7-8 lbs it ended up as. When he couldn't get me
to come to his way of thinking, he literally started swearing at me in the middle of the store,
in front of customers. He even threatened to kill me if he saw me out riding. The point is:
you don't need CNC to accomplish things. I think I've proved that. The old addage is true:
WHERE THERE'S A WILL THERE'S A WAY.

For me the school workshop is my workshop until I fully convince dad we need a lathe and mill in the man cave at home. :wink:

I've done "metal tech" which is the same as machine shop for 3 years now, and I'm heading into building next year which should keep me interested. Machining is nearly as fun as riding for me at the moment. I really enjoy it.

Sorry that I won't be posting for a while, I'm away racing a small tour and travelling, but I'll post some of my CAD drawings and concepts when I get home...

Don't really think you need a lathe for parts tuning. Just look at the complex work some jewelry makers turn out freehand. I'm planning on getting some diamond grit bits and have a go at gemstone carving myself.

Actually, most serious jewlers/watch repair have lathes.

Wasn't really what i had in mind. Watches are much more precise than deraillers. Meant artistic jewelry design/fabrication. Some carve wax for casting, but others forgo the extra steps and carve metal blanks.
