This is something that I've been working on off late as well,
This is an old style quill stem, for a 1 inch steerer, but the customer wanted a bit of a new school touch on it, a clamp that could accept modern 31.8 oversize bars. the quill is 4130 cromoly, the lower clamp is a very high end material called 17-4ph stainless steel, which is used in the aerospace industry for turbine blades. expensive metal this !! and the top clamp is 6082 heat treated aluminum alloy. CNC machined and fillet brazed construction. Since majority of the parts on it are steel, its a tad heavy, but the customer is not too weight conscious. By the way, this part wont be ridden in this part of the world, this one is heading straight to hong kong ! PSYNYDE going international, yeah baby ! Its not yet complete, some chrome and laser engraving remains.
P.S. the bar on the customers bike would be a bull horn, this pic is just for representation.

Tapped the BB, reamed and faced the Head tube.
Needs some post braze clean up. As you can see, on the faced part of the headtube There is a good penetration of silver ( the entire frame is silver brazed. yes, its real silver in there. expensive? you bet !! ) between the lug and the tubing. That means, this bike is ready to take on the bad stuff - head on !
A properly reamed and faced headtube is necessary, so that the head set can sit squarely on the headtube, Which results in smoother steering and ofcourse longer bearing life.

27.2 Seatpost Shim
Here is the Seatpost Shim for a 27.2 post. Lathed and milled out of a 304 SS tube.
The slots are here for a couple of reasons, Reduced weight and is a good place to feed in the silver, for a secure bond to the ID of the seat tube.
The top image is of the shim only, and the second pic is of the shim inside the seat tube.

I was working on this road bike for well over a year. Finally completed the project last month!
I've made bikes before, but none were built with 'finish' in mind. All the bikes I'd made earlier were totally ghetto ! but not the CAFFEINE !
Built from 'Columbus Life' niobium alloy triple butted tubing, this thing totally rocks !
I never intended to make a light frame, I'm not much of a weight weenie, But I'm happy with the way the whole frame turned out, just 1.4 kgs, it really makes my day when I'm out riding. It feels lighter than it actually is, thanks to my downhill bike and my dirt jump bike!
Here's the pic of the machine, taken by my good ol' friend Abhijit Nilakje, this guy is an ace ! visit his blog at http://rockscratcher.blogspot.in/ btw he's got the CAFFEINE there too ! this thing is addictive ! yeahh

re designed thrust link
i love my rm7 to the core, but my bike is an old school freeride bike, which translates to a very high BB, and steep head angles. ( new school FRbikes have slightly lower BB and slacker head angles )it was made when freeriding was in its infancy, it also is one of the bikes that brought out the whole freeride phenomenon to the world.
during those days, this bike was ridden only to be jumped off a 30 or a 40 footer ( no i've never tried this ! more on this some other time Lol !)
it was hardly used for RIDING. now when i take my rm7 for mountain biking, i cant corner they way i want to, because of the high BB, i cant lean into the turns. these days i enjoy taking my Shortfuse 380 DJ bike (hardtail) to the mountains, it corners like a charm as its got a nice low BB. but i end up being sore after a good DH ride. i missed my rm7's buttery smooth 7 inches of front and rear wheel travel to the core while ripping down the trails.
so i thought of resurrecting my trusty ol' steed. i wanted to lower the BB as much as the design of the bike allowed me to. i got down to business, designed the part in CAD.
got it CNC machined from super strong 2014 T-6 alloy. heattreated it post machining to T6 and anodized.
its just 2mm shorter than the stock linkage, but it lowers the BB by approx half an inch and slackens the head angle by the same amount
