Thanks Peter, It's an honour to be invited as a buddy (even from a Kiwi) and I hope you don't mind reciprocation.
My issue was the lack of tannin. I didn't realise it's importance till I saw the following
video last night,
(I'm not much of a reader).
I currently have 22 of the T&J models imported into Sketchup, currently working on the WS Tractor and have the MRAP Cougar, Power Wagon and Hydraulic Crane on order which should take about 10 days to arrive and a few days to import. I have uploaded the SU models onto dropbox. I have a mix of 2 versions, some with just the SU model and others with the plans for those that have purchased the plan (just to be fair to T&J and individuals' honour system).
The "$Train.skp" has models of both the locos, caboose, passenger, box and gondola in the one (can post individual if required).
If you give me your private email address (at "alex@karapens.com"), I can add it to the authorised list to download. If you actually own the plans, I will upload and give access to you to a copy including the plans.
Also if you need any assistance or tips with SU feel free to ask.
