So, before the chassis could go to Cornering Force, I needed to get the tub off the car. The tub was riveted in place, and also sat on a thin bed of mastic. If you’re not familiar with this stuff, it comes in tubes and sets like soft plastic. Like a more permanent version of blu-tac. But black. And more Solid. In fact, it makes me start sentences with conjunctions.
Sorry, back to the build. To get the tub off the chassis rails, i needed to drill out the rivets and cut through the mastic. Drilling, no problem, but getting through the mastic… difficult.
I tried a few tools:
- A Stanley knife wouldn’t cut through
- A hacksaw didn’t have access
- A hacksaw blade alone was too difficult to handle, and wouldn’t get through easily
- My ( … drum roll … ) 10k RPM air-saw did. It scares the willies out of me to be honest, being a gentleman who’s already had one too many digit reducing incidents.
The execution was simple – get it in the gap and move it slowly along. Result – all the mastic nicely cut through.
