Very Little Gravitas Indeed*

When I've gone to the trouble of isolating the track from the baseboard (a.k.a. sounding box) it just doesn't seem right to then rigidly fix the track to the plywood with PVA

Aberbig started with the foam running to the edge of each baseboard and I experienced the end sleepers losing support from the foam. From memory there were ten board joints to fix and the solution to the problem was already there in that the two fiddle yards had the 9mm plywood thresholds which mounted a 3D printed cassette end. I simply adapted it to each board joint.
I wasn't aware of any change in noise level when running at home. Mind you most running was on the oval with a couple of 37 on the front of every 16T I could muster (48) with something else going round the other way. I had retired and no longer cycled to work so I got hot on the trainer for 30 minutes watching the trains go round with the sound on. Happy days!

Ticking along slowly - still investigating track alignment jigs, now the pegs have a bevel applied and the slots a small wedge (web). So no more complicated but also fixes both units at the same height.



Although they did need a little filing to ensure they fitted together tightly.



I was favouring the sleepered version but gluing the chairs to the pla moulding wasn't too successful. Using butanone the chairs are fixed to the wooden sleepers far better than the pla sleepers. I do have some abs filament so I'm currently printing off another test piece to see how well I can glue the chairs to that.



In the meantime I've been finishing off the Sideline bogies with the ball races and sprung units.





Again that was another experiment - it worked out quite nicely so now I have a couple of finescale Sideline LNER coaches which I'm going to convert to Scale7 and I think I should be able to retrofit these sprung ball race units to them at the same time.
