Forgive me Spoke Wrench, for I have sinned...(6 posts)

|the headset bought from chucksbikes.com (for next to nothing) was a 1" threaded deal, but there was no star nut--it simply had a bolt affixed to an expanding nut contraption at the bottom, which affixed inside the steerer tube like a quill stem bolt. couldn't get it adjusted right, too much play in the headset, and it was constantly creaking. rode it 100 on saturday and decided it had to go.
sunday removed the fork crown race and headset cups with a long flat-head screwdriver and hammer--gently. used a 3/4" x 2" (diam x length) piece of pvc selected as fitted to the top of the new crown race (cane creek c2 hs), plus a 9" piece of steel tubing threaded on both ends, to put the FCR in place. greased the base of the steerer tube, put the pvc atop the FCR, then slid the pipe over the ST, and pounded it on. the pvc was a buffer between pipe and FCR. worked fine.
took some time verbally addressing and "resting in solitude" to get the HS cups pressed in. decided at first to use my 12" threaded bolt/washers/nuts, but it wasn't working as planned. attempted to put more 3/4" pvc in the middle of the "tool", as the CC C2 instructions say to only press the inside diameter of the cups. wouldn't go in straight. finally flung the homemade HS press and did the deed with a hammer and soft 8" 2x4, gently tapping either side or the middle of the 2x4 to get the cups in straight and flush. set in the cartridge bearings, top seal, top cover, cap, adjusted stem with bolt, tightened stem bolts, the rest is history.
worked like a charm and i can't tell the difference between this one and my other 3 built bikes, which were all done "professionally". put in 30 "spirited" miles and 20 commuting miles yesterday and am pretty pleased with the result.
only drawback was having to re-trim the steerer tube for a shorter stack height of the C2 vs the generic HS. i miscalculated a bit (LOL) and lost about 25 mm, which turned out to actually be a bit more comfy and closer to the saddle-bar drop on my other bikes. i learned lots about hacksaws, that's for sure.

|The hammer and block of wood has never failed me. Often the job is made easier by using a dremel tool on the headtube end of the cups to put a more gentle bevel on them to make starting them easier.|

|Couldn't get the crown race to seat fully on a new fork this weekend (using my home made setting tool made from a piece of steel tubing). Took a flat blade screwdriver and hammer to fully seat the race.
Bottom line is that prudent usage of heavy-handed tactics is perfectly acceptable as long as due care is exercised.

|that heavy handed tactics are OK given enough care. BUT, I also have an agreement with one of the local shops that I really like: beer for headset pressing. This is how it works: I bring them either a 6-pack or a 12-pack (depending on what I need done) and they press in my headset.
That way, I KNOW it was done right, I didn't have to resort to bashing things with a hammer, AND the wrench has a good time once he gets off work.
Saved myself a lot of money this way... There's a lot of 6-packs worth of beer in that Park HS press...

|how do you know the wrench using that press knows what their doing? If they do, great. But there are lots of hacks out there doing damage while using the "proper tools".
As for myself, I'll press a headset for a 12 pack anyday. I'll even do it for a 6'er. My headset press uses a piece of threaded rod with an assortment of different washers. I just pick through the box until I find some that fit tightly on the non-bearing surfaces. Of course, it helps to do the pressing before diving into the beers.

|Since I do all my own work (except for those WAY expensive tools that you only use once in a blue moon) I make sure that I go to the guys that are better than I am.
There's a few wrenches in San Diego that are top notch that I don't mind taking my stuff to. For the rest, I probably know more than they do!
Going to shops to poke around is an exercise in biting my tongue. I have heard some real doozies coming out of the mouths of shop employees!
