Stainless steel engine cradle/swingarm

I bought some 3/16″ stainless plate and 2″ square tubing back in November to make a custom engine cradle/swingarm.

I was going to build this over the winter but never got around to it.  I finally started this project this week.  The weather was all over the place – day 1 & 2 I was wearing shorts and a t-shirt and the AC was on.  Day 3 & 4 it was jeans and a jacket with the heat back on.  On the last day – day 5 – it was back to shorts and a t-shirt.

After triple checking my numbers, I started with these cuts:

Then on to the proper positioning of the cross-member:

One of the key items I needed to incorporate into this was an “anti-wrap” feature or bracing to keep the rear end from wanting to twist under acceleration.  This is the final product:

Last test fitting before putting it in the cart:

In and everything looks and lines up well.
