Anyone ever tried to reduce the height of the inside teeth of a campa 9speed cogset on a turning lathe so that it fits an 8-speed campa body?

Haven't you noticed that the spline pattern is entirely different on the 9 and 10 speed cogs? Even if you bored out the cogs, they wouldn't fit.

Well it can't be that different since I have already fitted an 8speed cogset on a 9 speed body without any problems. I rode with this combination for 2000miles without problems.

Even if the spline patterns were the same you then need to center the cog in the chuck. A three jaw chuck doesn't really get things centered and would only work with cogs where the gaps are divisible by the number three. So you'd be sing a four jaw chuck and then centering the cog with a dial indicator. Not terribly difficult, but should be pretty time consuming. The there's the problem of putting nothces/dings in the teeth from the chuck jaws, whihc can be worked out. Also, realize that some of the cogs may be heat treated to improve hardness so a carbide tool bit would be advised.

Probably a fun project if you have the time and access to the tools.

Sum just don't get it. Ain't always about the money or the EZ way out. Damn, wished had spent more $$$ on machine shop toolz 'stead of carpentry toolz, etc. Fun is where you find it.

cheers,

Oh I dunno - get a huge kick out of firing up the worm drive saw or putting my Super Sawzall through a wall to be demo'd. Nothing quite like a freshly sharpened chainsaw blade slicing through seasoned oak like it was butter and watching the fire wood stack up. Or a razor sharp chisel notching out the space for hinge plates. Or framing and siding with the nailgun inplaces where a framing hammer is hard to reach. Just bought an old used milling machine so now I can repair misbehaiving bike parts. Sometimes it's not about saving money, but just getting to do fine work with quality tools. the important thing is to have the right tools for the job.

Sometimes the grass is greener on the other side of the fence, but often it's crab grass.

'Cept for the milling machine have tasted all the others :)

Just bit on a Ryobi 18V cordless 4-pack ..."skill" saw; drill; "sawzall", flash light; 2-btts & charger for $199 Home Depot. Saving the bucks for a sliding chop saw ...makita, hitachi, the "yellow-brand"?? ...any input? Am building a 1950's filling station repclia garage and far back enuff off the road from the prying eyes of the building inspector in this remote mountain area.

My nephew got my wife's dad's old 1940's? worm drive Skill in the metal box and sold it at a garge sale ...arrrg! When worked as a carpenter 1960 Texas we used these for rafter tail cutt-off & typ Black & Decker circular saw was pop then. Have three sizes of chain saw gas and one electric as have 40 oak wooded acres. Could use a splitter though; maybe the old parked Honda's 4-cyl engine ?

Yeah, we'd make good neighbors! You up near santa rosa if i remember ???

cheers,

Naw, Santa Cruz county, though Santa Rosa is nice, it gets hotter 'n the hinges in hades during the summer and surf access is an issue. Good vino though! Terrible Two is a very worthy ride out of Santa Rosa, but not to be taken lightly. The wife is from Sand Diego and I spent three years there flying aeromachines out of North Island NAS - the golf club and private surfing beach that happens to have an air station and dock a couple big grey ships with flat roofs..... We'll have to look you up next time we head down to visit her side and we bring the bikes. I' guessing you're up around Alpine or similar? Just as long as its not Warner Springs - too many flash backs from the Navy survival/POW training.

Seen that deal on the Royobi, but I'm pretty set with my Bosch cordless drill (got it for $75 when Sears was blowing out the demo models and I can't kill it). Chordless sawzall is a nice, but most of the stuff I've done requires lots of run time and I have easy access to lots of power. I had a worry about about the Royobi quality - they took some pretty big hits a few years ago - probably took their licks and sorted it out. They make an interesting jobsite type of table saw - you can even mount a router under the table wing. Check out the new chop saws from Delta, though the others are good also. Big bucks for any full-on slider model. Been thinking about getting a splitter myself - have all sorts of access to awesome oak and madrone in the mts. here. Life is too short to burn crummy wood or split the stringy madrone by hand (stuff has amazing BTU output).

Just remember the building inspector isn't invited to any parties you might have. Rebuilt the 800 sq. ft. garage last year and "negelected" to invite our building inspector - damn my forgetfulness. If I had ahd the money and time I would have razed it. Termites agreed to keep holding hands if I added new wood. I negelected to tell them I'm going to gas them soon. Really like my 20" Husky chainsaw, but lately it's getting a bit fussy about chain tension. Notice that my buddies running Stihls can have theirs swinging in the breeze..... 'Lectric chainsaw doesn't do it for me - things go better with gas (and beer.) The husky blower and the 325 weed wacker are awesome. The weed wacker can be fitted with a blade that will knock down a 3' sappling in a blink.

Have become very skilled at trapping gophers living in the "sticks" - they've put the word out that my place is the "killing fields." The neighbor cats and dogs are very jealous that I only share the gophers when they're dead, but then they do the same and usually it's just parts.

Yup - we'd be good neighbors - pro'ly have fun riding too. We've got hills that will both drain and inspire you on the road bike. The super-dope secret single track through the redwoods around here is to die for - especially now that we've had just a tad bit of rain to knock the dust down and make the trails super grippy. Should take a g meter with me to see what I can pull in the corners. Pretty impressive riding community also - lots of up and coming as well as retired pro riders (road, CX, and MTB). Still waiting for the upgrade on my tree-avoidance software for the MTB - it seems to have glitches at the worst times....

Lemme know if you make a trip up our way.

I have never heard of this being done. Sorry to say, don't be such a cheap SOB and buy some new parts.

I never knew that Campa Shamals wheels were that cheap!
So if one has a pair of them with 8speed body that cannot be exchanged for a 9speed body one has to be creative!
