Just fitted a new chain and cassette. Had done a chain before but this was my first cassette. Haven't been out to test it yet though......may all fall to bits!

For the first time ever I have actually succeeded in truing a mountain bike wheel. It is off my BSO MTB, an old chromed wheel. I wasn't going to pay to have it done, the wheel isn't worth it. It had two kicks in it and they straightened out quite easily. I intend replacing them with alloy wheels when I get a bit of spare cash. I also found the wheel had a bent axle, so a new one is on order.

Put a new rear tire on the fixie, the old one looked like it had life still but something had poked through it side wall so I changed it.

Stripped and rebuilt my hubs for the very first time ever. Was surprised at how easy it is with the help of our Sheldon and park tool website. Replaced the bearings and the front needed one new cone. Living the dream!

Nothing is ever easy is it?
Just done my first flip of the stem but now I have an issue.
I removed the bars, undone the side screws and top screw and removed the stem so ok so far, but inside the stem there is a metal sleeve which sticks out at the bottom but when flipped it sticks out at the top.. but I can't move the sleeve
So on standard set up the sleeve sticks out at the bottom and flipped it sticks out at the top is this alright?
It dont feel as if its right but I dont know.

I have been teaching myself how to MIG weld over the last few weeks. It has taken a while to get all the bits together (auto mask, the right grinding and cutting disks, a local source of cheap CO2, regulator, flow meter etc etc
Here is a test piece I put together last night
I need to figure out what is causing the browning (oxidising) on top of the weld (too much shield gas or not enough) 40mm x 20mm x 2mm wall mild steel practice tubing

This is as it stands on the bike.. the sleeve pokes out at the top and the top spacer moves at the back or saddle side but not at the front as the stem is holding it down.

If you notice on the second picture there is a gap betwwen the stem and the spacer which wasn't there before..

I'll do that but thanks anyway..
@Boon 51 Is the metal sleeve you refer to simply a shim to allow the stem to fit the steerer? Once you flip your stem and get a gap between spacer and stem is the gap even all the way round or just part way round. Looking at your photograph of the stem fitted "right way up" the space between the top of the stem and the top of the steerer doesn't look the same all the way round, although this may be the camera angle. I am wondering if there is a slight angle on the stem top which will stop it sitting square on the spacer when upside down which would account for the gap. Sorry for the garbled explanation, I would never make a technical author.

Thanks compo it was the shim that was causing the problem.
Once I found out the shim would push out and be turned round it was easy.. I did try the first time to move the shim but I just didn't use enough force as I'm a bit ham fisted and didn't want to bend or break it..
When you have the shim out you can see it is angled.. like most things once you have done it once its easy..
Cheers mate..
