The slip-on muffler is an Akrapovic 1000cc beast that almost measures 20" in length. Sean planted the idea to shorten it to a more suitable length for a 600cc bike and in the end it wasn't actually that much work.

This chapter goes with the Muffler Bracket chapter because the old bracket would not work with the shorter muffler.

First step was to drill out the rivets and start separating the end cap from the can.

I cut through most of the can with the angle grinder, and finished the cut of the titanium sheet with a hack saw to minimize the damage to the muffler packing.

After shortening the muffler (see "Muffler Shortening") I needed to make a new bracket because the old one would cover my Akrapovic decal and Sean said it looks ghetto. I figured I'd bang this out in an evening but it ended up taking several.

I always produce a detailed drawing of the part I want to make on Fusion 360, this case was no exception... except I did the drawing by hand. This is probably why it took me so long to make a simple bracket.

Last night I went to work on the lathe making a set of swingarm spools, which engage with the bike stand to lift the back end for wheel removal etc. They can be purchased all over the internet for $20-50 but buying stuff is no fun when you can make it yourself.

For the first time I setup my Quick Change Tool Post with my new carbide indexable insert cutters. Holy did this ever make the job a thousand times easier. Took about half hour to mount all the tools and set the heights, but once that was done it's about 5 seconds to switch between tools.

As soon as I learned about Quick Change Tool Posts (QCTP) for the Lathe I knew I had to have one. They are beneficial from a turret tool post (what I have now) in that the individual tools are pre-mounted in tool holders, pre-set to the correct tool height, so tool changes (ex: from facing to turning) takes about 5 seconds, as opposed to about 5 minutes. The standard turret style tool post requires shims under the tool to set the height, and shimming for every tool change is what takes the most amount of time.

A few months ago I bought a Chinese QCTP from Amazon for $268, which came with 5 tool holders. I also bought 3 extra tool holders. The idea is to get all your tooling mounted in tool holders so that once their height is set, it's just a matter of swapping tool holders to change machining operation.

The Base of the QCTP I bought is supplied oversized so that it can be machined to fit any lathe. This chapter covers the machining of the Base. This project covers some techniques I've never used before so I wanted to proceed cautiously.
