hartleymartin Posted December 5, 2014 Share Posted December 5, 2014 I've found a good number of photos but I can't find any drawings or diagrams with measurements. I'd like to scratch build one in 7mm scale. Does anyone know of drawings somewhere? Perhaps in a book? Link to post Share on other sites More sharing options...

hartleymartin Posted December 6, 2014 Author Share Posted December 6, 2014 I've read through all those threads. In fact, I am now the proud owner of the Atlas conversion. I've gone through the instructions for the 4mm scale kit and found some good end photos. I think I just need a couple of good reasonably square-on side photos and I think I can extrapolate a basic working drawing based on known dimensions - wheelbase, wheel diameter, buffer height, etc. Link to post Share on other sites More sharing options...
hartleymartin Posted December 6, 2014 Author Share Posted December 6, 2014 Being such a small prototype, it has occurred to me that if anyone were ever to make a kit of this wee beastie, that it should be made largely from pewter castings, and probably could do with considerable lead-weighting. Although, I seriously wonder how much room there is for weighing the model as the tiny body will probably be mostly full of motor, flywheel and gearbox. Out of interest: Metal - Grams per cubic centimetre Lead - 11.34 Brass - 8.4 (varies)Tungsten - 19.6 Whitemetal - 7.1Steel 7.85 Looking at the relative densities of various metals, lead would still be best. I used to hammer lead fishing weights to shape to fit other models. Gold - 19.3 (but would make the model extremely theft-prone!) Link to post Share on other sites More sharing options...
hartleymartin Posted December 6, 2014 Author Share Posted December 6, 2014 There is a rather nice set of recent photos of a preserved example of this particular type of Hibberd Planet Diesel, but the closest I could get to a side-on shot was this one:https://www.flickr.com/photos/northamptontoffeeman/15379386697/ Link to post Share on other sites More sharing options...
hartleymartin Posted December 9, 2014 Author Share Posted December 9, 2014 I'm doing a couple of short courses in 3D CAD drawing over the Christmas Holidays. My plan is to have a crack at drawing up the 11t Hibberd Planet. I might then see if I can get someone to cast the body in pewter and produce a body kit. I'm also looking at getting another company to supply a suitable mechanism for it, possibly Hollywood foundry, or something from NWSL such as their "Magic Carpet Drive" Link to post Share on other sites More sharing options...
hartleymartin Posted December 9, 2014 Author Share Posted December 9, 2014 Anyone who can supply me with a detailed, dimensioned drawing of an 11t Hibberd will get one body kit free of charge including postage. Link to post Share on other sites More sharing options...
