The wtc is now completed and it fits...and it works. The end caps are on their way back to Paul H to have 1mm shaved off all round, they were just a touch too big.
I was going to install a 12v 4.5a/h gel cell up in the bows, but it didn't fit (grrr!) so I've ordered a 12volt 3700a/h nicad pack specially made to fit the space available.
Flood holes are drilled, shaft is temporarily fitted, so next job is to make a start on the detailing of the conning tower, finish off the 'scopes, and then make up the few bits on the deck.
I think I've worked out how to release the torpedoes, but that entails much brass work, so there's a job for my tame engineer. A friend in Bristol is getting the metal work that supports the rudder and rear dive plane made up for me, and as you know, Alfie is going to make the torpedoes operational.
Without the help of Alfie, Andrew Gray and his friend Terry, Dave at ACTion Electronics, Kevin Coombs, Ramesh, Andy Lawrence and Andy Oakley I wouldn't have even got this far with the build...I thank you all for your advice, assistance and hard work on my behalf.
