Ann Arbor Accurail kitbash


Robert kirkham
 

Thought I'd post an updated photo of my kitbash of one of the Ann Arbor 73750 series boxcars.  It uses the 4300 series Accurail boxcar, with modified door rollers, top plate, and strap bracing on the end panels.  The Yarmouth Hutchins roof, a wood running board and their 16" spacing 7 rung ladders (modified for the car ends) were also used.   The ends were scratch built (before I did the 3d drawing of the replacement end).   

Waiting for the Miner power brake parts to arrive.

That’s going to look really good when it’s finished.

Nice job Rob.  I would like to hear how you scratch built the ends.  Thanks

Trial and error!  LOL.   Well, I filed and sanded down the end to a flat surface, and filled in the mounting holes for the brake step.  This is fairly easy with the original roof off.  (I removed the roof as I wanted a wider roof overhang to match the prototype.)   Once the ends were flat, I 3d printed the 4 bulges.  2 or 3 holes were drilled through the end to allow gluing the bulges with CA from behind.  The bulges were tacked into place with Tamiya solvent (which won’t hold the printed parts long term), and then moved around until they looked about right, then the CA added from inside the car body.  A strip of .005” styrene was solvent cemented across for the panel seem.   Archer rivets applied per the photos.  

It's been a learning process both in methods and in accuracy to prototype.  I think I might do a better job with assembly next time - one end isn’t precisely identical to the other.  And the end details are wrong in a number of ways, which is why I have ended up drawing complete ends that correct errors.   But, since the model was already well along, I decided to complete it and save the corrected ends for another project.

Looks great Rob.  You mentioned a 3D drawing, do you plan to offer via Shapeways or other store? Please be sure to shar completed pix.

Thanks Rob.  Interesting that you 3d printed the added portions of the ends in your kitbash.  Nice job.  I have seen some kits from the resin car makers have the Hutchins ends but I have not seen the ends offered separately.

Thanks everyone for the encouragement.  It helps keep the momentum going.  

Yes, Chris, I’ve already had a chat with one of our friendly model companies and will be sending the printed part to be used as a master they can (hopefully) turn it into cast parts.  I’m not really that organized with hobby activity, so not sure just how fast that will be.
