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

[NW Mailing List]

Mike:

The general arrangement drawing shows the location of the bolts:

A good exterior photo is

I would suspect, without better evidence, that these are square head bolts, as that was more of a standard at that time.

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).
