Hi RD
It seems to me that the milling process would have to start from the top down , the tanks are out of the question , am I right in thinking the EM2 is 66mm long ?
Whichever loco you choose to have the treatment, the circuit board is going to have to go , the lights along with motor and pick up connections will have to be hard
wired which I've always preferred so an 8 pin decoder is much easier for that purpose than trying to tag wires to a 21 pin .
First on my list will be a Heljan Hymek as I think that could accommodate an EM2
I know that the great Legomanbiffo has done it with a '33 but as yet, there are no videos on how he managed to achieve it .
When the EM2's eventually land onto these shores, I'm sure there will be plenty of RM Webbers including myself only too willing to share their experiences
and perhaps their mistakes !
Now , all we need are those blooming EM2's ..........CHARLIE !!!!!!!
