I will be using the plastic sleeper and glue option for construction I think as I believe it might be abit easier, So I am wondering what type of glue is best? Would the revell plastic glue that I have be fine? I don't want to be destroying chair detail!
Logic would dictate that brass fishplates are used to help pass the current along, So I need brass and Plastic ones (for the turnouts) but what is the difference between the brass and plastic chairs? Are the brass ones just used when soldering it onto riveted ply sleepers or something?
For chairs are C&L or exactoscale one's better? Or not much in it? I will need the 2 bolt one as im going GWR location, Iv'e heard that the key is supposed to face the on-coming locomotive, however which way do they go around on a branch line terminus?

Last one is quite important I think, Gauges! Do I go for the fixed 18.83, or the one's with slight variations and make things slightly bigger at say +0.1 or + 0.2?
My shopping list currently contains..
Bullhead rail
1x C&L B7 turnout kit if its bullhead rail? (1 to learn from, 2nd to scratch build)
2 bolt chairs of some sort and slide chairs
plastic and brass fishplates
plastic sleepers
glue
cork base
track cutters
Gauges
Tiebars
I think that is everything, If I have missed something please let me know and I'll add it to the shopping list!
They may be silly questions but it saves ordering twice if I miss something, Hopefully will get started on the baseboard this week!
Thanks for your help
