Sebspeed's 750 Slingshot (part 2)

Looks good, transfer to aluminum

Fleshed out

In order to weld them on, I needed to figure out a way to hold each mount at the same height. I prefer fixturing vs working off dimensions and scribe lines. Fixturing always seems to turn out better.

Easiest thing to go off of was the rear set mount hole... but I didn't want to waste time cutting and drilling a temporary structure... the closest handy item did the trick

All I had to do was cut a taper in a bolt head to center it up, and add a piece of drop to the jaws to set the height.

Worked out well

Right, let's get this subbie mounted, I want to sit on it!
I cut some scraps of cardboard till I was happy, then rendered the top mounts in aluminum.

Not bad for non-cnc equipment if I do say so myself

In situ

Before I tacked the mounts, I drilled and tapped them for M6x1 bolts. Once they were glued in place, I transferred the bolt hole location to the subframe rail

I had to dress up the subframe rails a little to make room for the bolt heads

And all back together...

It even held me up without breaking, and I'm a fattie...

Tried fitting these, but they are not going to make the cut. Maybe fab something along these lines, but better looking?
