I'll stick around for this, if that's ok? Keen to pick up some ideas and tips.

Let me know what tips you're looking for - happy to help.

Well I've got a few resin transkits now, so I'm interested in how you modify everything to fit, and obviously the prep work that's needed to be done, before you hit the paint booth? I'm aware that resin doesn't like certain substances, so what are you going to use?

It's mostly a lot of test fitting. I was able to get drawings of the original including dimensions which helped. I made the mistake of accepting the trans kit instructions for some of the build steps and discovered that the front axle was 2.4mm too far forward. This was why I ended up scratch building the front springs. I use a lot of reference material (mostly from the internet) and draw to scale any parts I need to make. To take measurements I use a selection of steel rulers, compass and a micrometer as well as Tamiya tape for curved sections. I'll try and include some examples. I always wash the resin in warm soapy water and air dry. To paint I use Mr Surfacer as a primer - this helps show up any imperfections or bubbles in the resin and is also a filler. Larger holes I use either cyanoacrylate and accelerant, sanding straight away as it is much harder than the resin when fully cured. I also use Green Stuff and Mr White Putty. As the Mr Surfacer is a filler as well it dries quite evenly and only needs a light rub over with 2000 grade wet and dry sandpaper. I usually use Zero Paints over the primer as although they smell they airbrush well and are rapid drying.

Excellent information! I look forward to seeing this come together! I have a Mack F type, Diamond T, Mack R 700 and a few others, that escape my memory. I'll try not to chip in, and give everyone else a chance to comment. Thanks again buddy 👍
