Hi can anyone please advise why a 10mm hole is required for mounting under baseboard a peco pl10e motor and not a 2mm x 6mm slot ? Thanks in advance
Simply because it's easier to create? :D
I gave up creating slots decades ago, I just use something like an 8mm-10mm drill. When ballasting later, you can use a little card to disguise some of the hole if desired, or simply guide the wet ballast around the hole to reduce its apparent size.
I reckon the holes for the point motor rod are not very visible in this photo? (holes are top side of the points)

I drill a hole of around 8-10mm because I haven't got a 2 by 6 drill! I'm sure there is no problem with a slot other than at 2mm wide it would have to be far more accurate than my woodworking/track laying skills allow. The important thing is that the point motor rod mustn't touch the baseboard. Even a slight contact with the side of the slot will stop it from working perfectly.
Thankyou for advice will save me a lot of work and can see what's you mean as there is quite a bit of sideway tolerance on the pin
