I am now working on the $899 Marin Kentfield 3. Again it has the same geo, groupset/brakes, as a $14,400 Creo SL that does not come with pedals. I can get the motors BB only an inch and a quarter in and it hits something. I have been grinding and filing for an hour. The owner has had surgery on her left foot, so I am making it a throttle ready bike. I normally don't but she is the kind of exception that proves that rule. Her foot is still in a Frankenstein velcro boot.

After hours of trial I finally got it. I wrapped a large bit with microfiber to almost 33.3 mm and then added 220 grit 3M emery paper and honed it out to a polish with a drill. It was just not one burr as usual. The entire center needed expansion. Now it it tight but goes in. I like things that are tight and go in all the way. The entire job should have been done in the time of fixing that one thing. What a PITA. I falafel. It was due tomorrow by train delivery but it will rain, so I bought an extra day to finish. Can't ride a new bike in the rain to the station. I hope you guys take satisfaction in my suffering.

Your suffering is uncalled for.

Adjustable spring tension and everything.


I remember making a similar tool to what you made.
I was trying to hone out an aluminum tube for my windsurfing boom.

I needed a three foot long honing tool so I used an orange fiberglass rod from the dollar store, (a ¼" driveway marker rod) and taped a strip of emery cloth to the end.

I just coiled the strip up to the ~1" diameter of the tube, and stuffed in in the tube.
It worked, but it took forever.

I bought one of those with a freind about ten years ago to hone his cylinder on his 10 horse riding mower.

After we got home from the 1½ hour round trip to the store, we opened the package to find that it was used, then put back in the package and returned.

The guy even reused the staples in the package to make it look unused.

The guy must have honed his cylinder without removing the piston, because the stones were only worn and gouged half way up each stone.

After thinking about it for a while, I noticed that my freind had clothes line poles that were made from 3"-4" steel tubing, so I stuck the honing tool in the rusty pipe and managed to resurface the honing stones, and then we managed to get his cylinder honed out properly.

Here's what the robot says to do,..

We thought of that, but we knew that we'd make a Fricken Mess of the stones trying to keep them square and flush, so I still don't want to make freinds with any of those stupid robots.
