Thanks guys! Charlie, Owosso is about 20 minutes NW of me. I was over there last evening.

Spent today working on the floor again. I made up templates for notching the rear bulkhead panel around the clearance tunnels.

Once those were done we trimmed a sheet of 20ga to size and laid out the notches for cutting.

I cut them out with a die grinder and cutoff wheel and cleaned them up with a stone in the grinder.

Test fitting the panel.

Once we did a little fitting we clecoed it in place and marked the tunnels for trimming.

Once the tunnels were marked we pulled one out and I laid out cut lines to trim to. We left it about an inch long so we could roll up a flange for welding to the floor.

After a few runs through the bead roller with the tipping dies in place we had a nice flange that only took a hammering to get flat enough to cleco in.

This is under the floor. We had a bit of fitting to do to get it sitting right.

Once we had everything fit together we put a couple of cleco's in the top flange and called it a day...

The fit is pretty good underneath. This will get tightened up a bit while we are welding it in.

Thanks for watching.
