Help with 2/4 minute conversion

[Operafan]

I recently picked up the pieces to convert my Triumph B to a 2/4 minute machine, these include the mandrel shaft and feed screw, etc. and end pivot, also the metal piece with the 2/4 minute switch and indicator. All I got with it were instructions for a Home B conversion, no mention in that of the switch. Does anyone have a set of instructions for the conversion (the simpler the better)? Or better yet, any experts making housecalls in Manhatten?

Wyatt has the instructions on his website, and they're probably a bit easier to follow than the original instructions

Thank you. This is extremely helpful, and I am reassured that I have the correct parts (stamped T and B as Wyatt says), but still don't know what to do with the "selector."

Ah, I didn't read through it, and there's no mention of the installing the selector there either.
Is it the same type of selector as pictured in Wyatt's parts list?

It is very similar, but mine has a bit longer arm from the selector pointer coming down past the pointer pivot about ¼" and ending with a screw that must attach to some part of the mandrel mechanism. It is clear that the loops go over the bar carrying the carriage arm, there is a screw at the bottom that would rest on a bump on the upper plate (do I drill a hole for it, or is it just to adjust the angle?) and then the screw at the end which has to go to something for the selector to select anything.
