Put Sentinel into this search  to get all the issues

Hi Joe,

I scanned those articles a few years back when I was trying to design a 100HP Sentinel in Gauge 3. It looks like it builds into a robust 5" model but does deviate from prototype scale in a number of areas. I was very fortunate that a member of the Sentinel Drivers Society (the road type) had some original GAs of the engine that he kindly photographed for me. I spent some time re-drawing these full size in CAD (and adjusting for the parallax errors) before scaling it all down by 22.6 (to G3 size).

A friend made resin masters from the CAD drawings (two main body parts) and I built two frames/motor-gearboxes for the prototype/test models – obviously ours are battery electric models and half the size your 5" model would be. There is a photo of my version of the finished engine here:

I'm away travelling at the moment but if you PM me, I will dig out the scans of the articles and if you wanted the CAD (2D) then I'll provide that too (for personal use only).

Regards,

IanT

I too have the Constable articles scanned,it's one of those 'wouldn't it be nice' projects. I've seen a completed 5" version at Doncaster show. The wheelbase is very short. If anyone knows how well it runs I'd be very interested. In the meantime here's a couple of drawings I found on the interweb.
I've sent a pm to IanT.

I'm building a Sirena at the moment. She's just over half built with the chassis almost complete,
