Scavenger! Build Part 15 Engine Mount Gluing

A dowel was measured from just below the upper centering ring to the rear of the mount tube.
A ring of glue was added to the top of the rounded dowel.
The glue ended dowel was set in the mainframe tube up to the pencil mark.

The dowel was rolled around the inside of the tube transferring the glue into an even ring. Keep an eye on the pencil mark and use the dowel as a depth gauge inside the tube.

Two more applications of glue and the mount was slid into place.

TIP: As the upper ring reached the glue, the mount was twisted before reaching the final depth. By twisting the mount the bead of glue will be evenly spread out by the turning centering ring.
Before inserting the mount, take a moment and plan so you can make about 1/2 a turn to smooth out the glue ring. Think about where you want the engine hook to end up (between two fins?) and the engine mount tube depth. (Even with the mainframe tube or overhanging the back.)

Slide in one of the TTW fins just to make sure everything is where it should be.

If the mount is flush with the mainframe tube, use a block to make sure both tubes are even.

I'm using one of my sanding blocks here. Turn the block to the side to clear the engine hook.

The lower ring got a fillet from the back applied with a dowel.
