Time to install the engine mount. Test fit with 3/16 bolts.
I have found that the nutplate for the fuel pump is riding against the lower mount. I will need to relocate this nut. After a few hour detour the result below.
This is what is on the back side of that nutplate
Final drill and it looks good

Canopy Roll Bar and support
This next component is the roll bar. In case I decide to land upside-down this roll bar will keep me from getting crushed. I start by fabricating the attachment tabs. These tabs will be installed on the back side of the longerons.
Here is a shot of the Bar while I am deciding which direction it will be installed.
Test fit with 3/32 inch holes. I did have to move the the holes to the rear of the plane because I ended up not having the edge distance on the base of the roll bar when using the holes in the plans location. After some head scratching and careful measuring, I found that the Bar base was shorter then it is supposed to be. Easy fix by relocating the holes. Good reason to test fit with 3/32 holes.
Now install the forward support.
