Phat Trakka -
Part 5: Bump and Grind
So much to do, so little time
The first item of business here, was to cut off all the parts that will not be needed in the new build. It wasn't clear what the right sequence would be. Some things, like chopping off the footrest mounts clearly wasn't on the critical path, but sometimes it's best to just start doing something and see if a clearer picture emerges. Or as Edward DeBono put it more elegantly - motion generates direction.
| The first things cut
off, were the footpeg mounts. They were cut through towards the
frame with a cut-off wheel, and then pared off with a cold chisel.

Next to go were all
the various brackets, such as the water reservoir tank mounts, which
would not be needed.
Then the rear shock mounts were cut off. I actually did that in a couple of steps in case I had a change of heart half way through. |

With the shock mounts out of the way, the rear sub frame support tubes were cut down in their prime and cast aside on the growing scrap pile.

| On a roll now and no complaints from the neighbors - yet. Off came the top tube and the sheet metal around the steering head. |  |

Only a couple of hours of work and my hands were numb from angle grinder vibration. I was drenched in sweat and iron dust. Fortunately those ear defenders and eye shield were doing a great job and the thick leather gloves saved me from a few potentially nasty cuts and burns.

tubes.

That was the easy part. It still had to be cleaned up and then it was time to plan for the new tubes. Chrome-Moly tube is available from various places, but I got mine from Aircraft Spruce. Their prices are reasonable and turnaround time is amazing. My welding ability leaves considerable room for improvement and with the cost of a good TIG welder being not insignificant, this job was headed for Advanced Joining Concepts in Elk grove, IL. They had welded squish heads and engine stands and damaged crankcases for me, so I knew they could take care of the welding.
