Big Girtha Rebuild Part 9 Engine Mount

Cut out the circles as best you can with a sharp knife.







You can sand to the edges of the inside engine blocks using 220 grit on a dowel or back end of a Sharpie.

Here's the finished mount - no chance of the ejection charge blowing out the back.

The two engine mount tubes fit close to the inside walls of the Quest 40mm tubing. Ideally you should have a second lower centering ring but the fit is close enough it might not be needed.
