I was wondering if anyone has evaluated any project management software for planning and tracking progress in building a homebuilt. Being a software developer, I routinely deal with Jira and…Continue
I am trying to figure out the rivet hole placement for the diagonal L-angles on the side skins.The diagonal that is between the horizontal tail frames is well specified. However the placement of the…Continue
I am trying to form my firewall. I have made the form according to the plans. However it looks like the forming process is going to be a little different than that of forming the ribs.From what I…Continue
I finally drill out the holes to final size for attaching the main and center spars together.
The video below describes the process I went through. Hopefully other scratch builders
will find a few useful tidbits of information when they get to a similar point.
On to assembling some airplane sized parts!
