Estes Patriot Build #2056, Part 3, 24mm Engine Mount

I'll use the heavy card stock rings that came with the kit.
To enlarge it for 24mm engines:
Trace around a BT-50 tube. I used a heavy walled BT-50.

After you trace the line, look at it closely to be sure the circle is centered. If not, erase and try again.
Sometimes it takes a second try to get it right.

Note: There is only one card stock piece in each kit. I am building two Patriot kits.

To get the new diameter fit close, cut slightly inside the pencil line.
The line you traced in the first step is just outside the tube diameter.

With all cutting, don't try to cut through in one pass.
A few lighter passes is better than a hard single cut.

Check the fit on the 24mm engine mount tube.
If it is still too small, widen the hole with some 220 wrapped around a finger.
Sand a little and check, sand and check again.

Build time:
Cut 50/60 rings = 10 minutes
Total build time so far = 30 minutes
