First of all i'm sorry if anyone is offended, i cant imagine you would be but there you go. Twas all done for a bit of fun and cos i'm a tinker  :LolLolLolLol:

So... a while back i stumble on this ad on the museum in a thread about rare parts



I was really intruiged by the concept and i wondered why i had never seen one. I looked around for a while hoping to buy one but drew a blank. There are only 2 magazine ads on the net for it and precious little mention so i councluded they probably never went into production and the challenge was set.  :D

I looked into getting one machined but the quotes were pretty steep, what i needed was an old school machine shop with someone who could have a go at it in there lunch break or something but those kind of places seem thin on the ground these days so i decided to ask a waterjet cutting place i know if they could help.

I bought an off cut block of T6 ali, drew up a few simple cutting files and dropped it off with them to see what they could do.




I also got them to cut a few blanks (the piece above the block) for future ideas  ;)


The measurements were quite tricky and i had to reverse engineer the dimensions from the stem post and handlebar carriage in the ad which i could be certain of correct measurements. It still took a bit of heads scratching as the magazine ad pic is at an angle so forshortening had to be considered.
The length of the carriage was reverse engineered fron the dimensions of an odyssey v3 stem front and side wedges  ;)

The parts come out with a shot blasted face to them which isn't too hard to knock flat. I had to cut the round back profile by hand and file smooth. You can just make out the scribed mark in this pic



Next i bought one of those cheap ruption suntour style stems off the bay and carefully cut into the back of it to release the stem post. Luckily the pots mod bolt and washer were a perfect match to the ACS one  :daumenhoch:

I drilled a 21mm hole in the base of the stem and press fitted it in with a big fook off vice the missus's dad gave me a few years ago. Then i fitted an ACS rotor on the shaft and marked for the hole for the cable adjuster. This was then drilled and tapped.

My measurements must have been half decent ac the bolt on the rotor just clears the handlebar carriage  :daumenhoch:










A trip to the powder coaters and a few vinyls cut at a local firm and she was all but done  :daumenhoch:









Then came the naughty bit, with rad down i thought i may be a bit of fun to bung it in the rotor bag and see what the reaction would be once we were all back together.

Sorry guys, hope i'm forgiven  :D

GavinDavis:
That is awesome Clint!  Nice work once again mate!  What was the total price to make the stem?  :daumenhoch:
