I’ve got a bike project with half of a frame

If you recall this was the front triangle of the frame we used for our rear triangle on the Double Banger Tandem Project. Not wanting to have it go to waste, I decided to use it for a project that I’ll later reveal. But for now, here’s some pics of it. I used some Mother’s Mag Polish on it to bring out the mirror finish I had laid down a while back.

I’ll probably touch it up with some 2000 grit sand paper and do another round of mag polish. So this project of mine, you might be able to see what I’m up to in the photo below. There are some obvious hints.
