It finally got cool enough tonight to venture outside with my welding gear on.
First thing I thought I would tackle as a cube, so I cut 12 pieces of steel to the correct length and started to join them together. The first lesson I learnt is that these magnetic guides from Harbor Freight:
are *the* best thing to use when trying to get stuff perpendicular. I did try a right angle picture frame clamp, but I ended up with a distorted square, so rapidly abandoned it.
The steel was 16 gauge, so I set the welder for 4.5 feed, and E power setting. Worked really well.
When you are MIG welding you have to sure of two things:
1. You have the gas on before you start…
2. Clean all joins with a flap disc in an angle grinder – it really can’t be too clean.
If I can make about a dozen or so of these cubes, then I think I should be ready to tackle the Lotus Seven chassis.
