Got the last of the work done to the bumper, end caps for the corners, gussets welded, and everything ground down smooth.
Just finished up the vents for the radiator. Ive had a surprising number of people ask me how do you cut oval slots or even square holes in steel. Maybe this will help those folks...
Get it all laid out where you want whatever shape it is you are cutting, in this case it will be rounded slots.
Pick out your favorite sized hole saw, or drill bit (1-3/4" in this case)
Connect the dots...so to speak.
Then cut along those lines. I normally use a thin cutoff wheel for most of my stuff, with a little patience, practice, and a whole lot of safety, you can do a LOT of cool things with them. There are a couple ways to make the cuts, but this is the easiest for me. I have a plasma, but the line is only as straight as your hand moves = lots of grinding usually. I also have a CNC Milling machine that would have done it, but I would be finished by the time I wrote the program... a manual mill would work nicely too though. Anyway, this is what we were shooting for, easy peasy.
Thats pretty much it for the bumper build. It will get cleaned down well with acetone, sprayed with an Etching primer, and probably 3-4 coats of semi-gloss paint for ease of touch up if/when Josh beats on it and scratches it up.
I was also asked in a PM if I welded the backside of the plates too.... Honestly, a good welding machine, some skill/experience, you shouldnt have to. To a point anyway, thinner material such as this, shouldnt be an issue. Not much point in welding it if you dont get full penetration. It essentially is 'welded' all the way through. This photo shows the penetration through to the backside. These are all cell phone pics, so excuse the crappy quality, but you get the gist.
The next pictures should be of it painted, and mounted on the Foz.
