Early trial fitting of the next baseboard, which I designed yesterday evening and built today. This Easter has been a write-off as my partner is still in bed getting over the COVID infection I first caught over three weeks ago.

This is the first of three that will bridge the gap between the helix and the board in the back left corner of the room.

This board is in approximately the right position and the hatched area is to be cut out to ensure the board doesn’t interfere with the helix.

That’s it until the end of the week. I need to decide how this board is anchored to the helix board, and there is more than one way to do that. Needs some consideration.

Another round of trial fitting of all the rear baseboards now that the left rear corner board is permanently installed. You can get an idea of the absolute chaos in the room with this wide-ish angle photo.

The board that isn’t in place on the left needs some small adjustments now that the corner board next to it is 2cm further forward than the others. There will also be a step in the backscene boards where these two boards meet that I will do my best to disguise with scenery.

In 3D printing news, I have swapped the 0.4mm nozzle for a 0.2mm nozzle and now everything takes 4x as long to print, but, oh my word, the detail.

I am now in "production" for the PCA009 & GUV designs. I needed to stop tinkering and actually make some "final" versions.

Currently printing a GUV and 2x PCA009. 40 hours remaining on an estimated 60 hour job (although it tends to over-estimate, I'm expecting this to be more like 43 hrs total, based on previous.)

Top tip: get the design right first with the wide nozzle.

Today I learnt that Kadee #19 couplings are not long enough at 10.7mm for Accurascale Mk1 coaches where the NEM pockets are recessed quite a long way back compared to most other rolling stock I own. They couple up - just - but the buffers are almost touching and a rake of them won’t go around a 500mm radius curve (the tightest on my layout).

So I’ve ordered some #20 couplings (11.7mm) which I’m hoping will add enough length to give enough clearance. If not they’ll get used elsewhere and I’ll use magnetic couplings between the coaches instead, with a Kadee on each end of the rake.

All the other rolling stock I’ve added Kadees to have been fine. Most locos need #19 while everything else is fine with #18 (8.6mm), even the Syphon Gs which I thought would need #19.

The same layout also had two very well modelled cyclists going round the church. Very cleverly done with a hidden conveyor belt with magnets under the road surface, but what really caught my eye was being able to get the legs pedalling. #ModelRailway
