Firstly I have completed the Laser Rail Bits timber trestle bridge and fitted it with my 3D printed 1 1/2 inch square nut/bolts with 3 inch square washers and the bridge came out very nice. I followed the instructions and stained the timber with a Raven Oil and methylated spirits mixture. I did find that I had to make the mixture a bit stronger than in the instructions though, possibly more dense timber. I also noticed that the line drawing of a trestle in the instructions seemed to be incorrect in regard to how the diagonal timbers would go onto the piles. I will contact Rod Kelly of Laser Rail Bits about this.
As Rod had already laser marked the square nut/bolt/washers on the timber so it was an easy task to drill a 0.6 mm hole and insert the 3D printed ones.

I still have a few more things to add to the building but these will be done once the handling of the building is basically over to prevent damage. There are two flag poles coming out at a 45 degree angle from the upper floor on the Tamworth side, some double flourescent lights projecting out in several places as well as a couple of 'stink pipes' that come above the top of the building.
The next thing to do is to work on the brick platform faces, these will be made from Slaters brick sheets and it will be next to impossible to connect them without a join showing.
Items still to be done will be station signs, the signal box, small cast iron signs for Station Master, Men, Ladies, etc. and the surface of the platform.
The last thing I have done recently was to present at the Modelling the Railways of NSW 35 where I gave a talk on practical information on 3D printing. The talk seemed to go over well and I had about 60 attendees over three sessions. A good day in all.
Here is a sneaky photo taken by Zane Maber.
That's about it although I have been doing a lot of stuffing about with my two 3D printers as well.
