In response to questions raised by fellow members of the 3mm Society;-
The layout is 18' long by 10 feet deep. There are 12 baseboards sized between 4' x 2', 3' x 2' and two corner boards 3' square but angled off at 45 degrees at the outer corners mainly to avoid furniture in my garage. A future blog will include a track plan.
Track is pinned down on the hidden parts with no cork or polystyrene insulation - I like to hear the trains coming!! To do this without distorting, I first drill a small hole (0.4mm) just into the MDF then place a square or oblong file with the teeth facing down on top of the pin and parallel with the track and tap hard with a hammer. This avoids distortion and prevents damaging the track with the hammer.
My next blog will show progress on track laying this spring and focus on board joins.
