When you build stuff yourself, going out and riding it is your testing! That's how I've always tested my parts. You could do some finite element analysis provided you have the software and you actually know what you're doing.
Tillquist, very fine job! This is one elegant stem. In fact I think it is the nicest stem I've ever seen - beats everything you can buy!
No, i don't have a computer software, so i can test it's before i made the stem...
The Custom made TT-bar
i made last winther still hold
...so i am sure this stem also will hold....
Look ma, no hands! Look ma, no teeths!
I looked the images, and came also bit worried, although it looks quite impressive. Did you let it run trough a FEA-program at the first stage?
I have no FEA-program to run it trough
Very nice work! How long did it take?
I am not sure, but aboute 23-28 hours....
3-4 hours to draw it, in AutoCad.
6 hours in a CNC Lath.
10 hous in a CNC Vertical Machining Center.
2-3 hours to made some spec tools, i use to made the stem.

Looks nice and the weight is good!
why did you choose that angle - looks like alot of spacers under your stem?

This stem are made for my road bike, i will made a -5° or -10° for my MTB bike... so this stem are only on the MTB to tray it out.
