I read that post. Looks like abusive use. Mags are not intended for hard use. Gear derailleur would also not hold up. Manic mechanic style sprocket would slip under such hard use.Let me know how the wheel holds up mine ended up cracking twice.
You have hy22 rims.ya the wheels I had must have been Aluminum they welded just fine. Maybe Ill look more into the wheels this guy got. But from his picture they look the same as the wheels I had with the bare metal showing where the brake pads hit the rim.
I worked at a shop where we had to do some machining of magnesium parts. We were required to have a class D fire extinguisher on hand if i remember correctly. - Also I was in charge of keeping the kept the area clean, and so gathered up the "scrap" that was machined off (chips and curly strands). We would toss small envelopes of that stuff into our beach fires. Man it burned bright!Cylon, Yep if you welded them and you had the hy27 rims they are cast aluim and then the rim area is machined shiny and smooth for squeeze rim brakes. I've use 2 sets of each. I use both the aluim mags and the Magnesium mags on smooth roads only so I've had no problems, but its pretty scary that your aluim wheels cracked like that. You could of had a serious injury. Magnesium wheels probably absorb vibration better than aluim from what I know. Also if you would of tried to weld Magnesium the wrong way that could of been a big campfire in your garage. also water cannot be used in putting out a magnesium fire. It can be welded using a tig system if you use the right filers etc and know what you are doing, needs to be done by an experienced welder who understands this odd alloy. check out the link below.
