Looking for a CF cab image - car side bolts, under cupola

[NW Mailing List]

Nice work as usual, Mike. That would make a good addition to anyone who has unbuilt kits in their position - they should take advantage of your offer.  Thanks for the pointers to the general arrangement, Ken.

Ten or more years ago - probably more, I made a cupola-bolt drilling jig out of card stock (an index card) with the holes reinforced with CA. It worked well. My dad (also on this list) eyeballed his, because he has that skill. (Side note, I made a decal guide using the same materials - the CA in that case was to waterproof it).

Which reminds me that I promised a write-up on building the AMB models a year or two ago (again, probably more).

I am making one for AMB (the cupola length is 0.4mm longer on the AMB so the positioning tabs don't fit over the cupola.  I don't have any OMI models to try it on. I do have a Div Point, but I don't imagine anyone wants to drill into their DP model.

They take 2 hours to print, but I can print about 10 at a time. It costs about $0.12 in resin to print.  I could scale up to O Scale, but you would need to send me a very precise measurement.

So I switched to the Dremel on lowest speed with a 0.7mm drill bit and it drilled easily.  I think I could have used a 0.6mm if I tried with the dremel first.  Someone already shamed me into buying brass parts, instead of plastic.  😉  (Thus my initial question.) If I'm going to buy some Precision Scale detail parts, I might as well buy the right style and size.  I have 5 more WSM and 3 more AMB models to drill.

The two positioning tabs fit over the roof and match the angle, and around the ends of the cupola.  The orange pieces are print supports that snap off after it prints.  someone better than me probably could have made this in 5 mins.  It took me 7 prints to get everything just right. The last thing I did was to raise the holes slightly, as the two upper bolts are supposed to be just above the top of the side window frame. I drilled mine just a little low (bottom pic).
