This is the finished central engine mount.
You can use as many as six A10-Pt (plugged 13mm engines) in the SRMs.
Six engine blocks are glued into six BT-5 SRM tubes.
I used a dowel to get the glue into the tube.
The dowel was marked a little short of 2 1/2".
A glue ring was applied around the edge of the dowel end.
The glued end of the dowel was inserted into the tube being careful not to get glue along the inside of the tube.
When I reached the pencil mark, the dowel was rolled inside the tube, transferring the glue at the correct location.
An engine block was inserted and pushed into position with an engine casing. The casing overhangs the body tube by 1/4".

TIP: Half the job of getting an engine block into position without freezing in the wrong place is simply having everything ready and at hand.
Have your marked casing, marked dowel and engine blocks in sight before even thinking about using glue.
