Ok finally finished the lose ends on my Lionel SP RS-11 and finished My NP RS-11 this morning.
Procees was the same for both. The NP RS-11 was done with lessons learned from the SP RS-11.
After removing the shell from the NP RS-11 I pulled out the dremel and trimmed the frame by about a half inch and at the same time cut the pilot
Next did some additional trimming on the pilots the started assembly. Using epoxy that rated at 1800 lbs per square inch.
Drilled out the holes and mounted the Kadeee 743s then applying copious amount of epoxy, mounted the pilots to the shell. trWhile the Epoxy was curing( recommended overnight) I pulled the trucks removed the claws and what was left of the pilot, then trimmed off the tabs to lower the engine.
Reassembled the engine and let it sit over night. As you can see I am able to remove the shell without having to remove the pilot.
This morning I rounded out the pilots where the spacer was mounted, since the Lionel pilots are squared off and the RS-11 are not.
Then ran the NP RS-11 under a load to insure the pilot stayed secured to the shell.
