Evening all, I've got a few repairs to share this evening.
First one is a set of exhaust headers for a Yamaha FZ1. The owner was unlucky whilst riding to have a brick bounce up and hit one of the down pipes.
Being stainless steel makes them a tough repair to remove the dents because you have to get the metal hotter and use a higher pressure to manipulate out the damage. On the plus side though they don't need rechrome afterwards and so can be finished off with a good polish.
Still on with the exhaust theme this next one is a pair of exhausts for a Suzuki GT125.
These had the usual dents and scrapes in various places but also most of the baffle chambers were either broken or mangled so a lot of work was required to repair the insides too. Add to this you can see from the photos the amount of carbon build up over the years which will strangle the engine performance.
The end result are a pair of pipes that will perform much better and chrome plating companies are unlikely to refuse plating these as they are completely clean inside so will not contaminate their plating tank.
The next repair is also for the GT125. This time the rear mudguard needed attention. Again it was quite beaten up with dents and cracks but also for some unknown reason someone had cut out a piece from the front end.
This mudguard is only 0.9mm thick so it takes time to butt weld a new section in place and blend in so the surface finish is flawless to the required standard for rechroming.
Last job is and aluminium oil filter housing I think is for a Yamaha XJ900. The local vapour blaster discovered a crack in the o ring seat.
This was very a delicate repair because I had to build up a 1.5mm thick "wall" and then re machine the radius for the O ring to seat in original position. This in itself creates a challenge because I need to ensure the housing sits concentric to the rotary table. So to do this i made a mandrel for the housing to fasten to then grip the mandrel in the rotary table chuck.
So what at first appears to be a simple welding job required much more work.
