    Aluminium is strange stuff to work if you're used to steel, it's taken me a while to get the hang of it. Making something else first, like wheel spacers is a good idea, as it's not such a loss if you mess up and it gives you a chance to get used to working thick aluminium.





    I've been re-drawing my the plans for the triples and getting them checked over. I hope to mark them out ready for cutting later this evening.

    This is way cool to watch come together.
    Pit bikes come with Marzocchi forks? Shock, too? Wow - I had no idea.

    Everything looks great so far! But maybe angle down the shock a bit like DC said, the swing arm has a pretty crazy angle on it.

    Yeah Marzocchi make forks for a few different types of bikes.

    I haven't lowered the shock mount of the swingarm anymore as the angle affects the amount of leverage on the shock, and the shock is already quite hard and the angle is already less than it is on a pit bike. I'll see what it's like when she's rolling again.


    Got all the holes drilled out on the yokes today, if all goes well I'll hopefully get them shaped up tomorrow and then I can finally start getting her up and rolling.

    Took me the whole day to get the bottom clamp shaped up, I'm not looking forward to another day of it doing the top. I'm really starting to hate aluminium...

    That's a nice looking piece. What tools are you using to shape the aluminum?

    I'm using a mix of drill, grinder and jigsaw - nothing is quick with inch thick ali.

    I haven't cut the tightening slots yet, if you look at this picture you can see them marked out.

    Looks great with the limited tools you have... I'm the same... if it can't be done with a grinder, etc., I can't do it

    Thanks guys.

    I had to go to an engineers shop yesterday to get a wider front axle turned, so while I was there I asked them to rough out the 2nd Ali triple for me - wont be ready till next Friday, so today I decided to have a go at knocking up a set of steel ones - a few hours later and they were almost done, just need welding in the morning.

    Got the steel triples welded up - can finally start putting something together now.



    Another piece of the jigsaw arrived in the mail today - should look good on her.
