Post war 100hp Sentinel

Hallo James,

 

That's the 'Sirena' 5" locomotive James - which was actually the first thing we looked at (to base our Sentinel loco design on) however we wanted something a bit nearer to scale and decided Sirena wasn't a good basis for that. However - for anyone wanting a live steam passenger hauler, then it's an excellent use of a Stuart Twin. Station Road came up on the ME website recently, because they also have a very unusual 8-cylinder uniflow engined version of a 5" Sentinel on their site at the moment. That engine might involve a bit more work than a Stuart Twin though.

 

Nice photos of the NRM engine - I don't think we found these when we were looking for them a few years back, although we certainly found quite a few - and there was one of the NRM engine that I found particularly useful (not sure where it came from now - so I'd best not post it here).  What scale is the Sentinel model shown on your link?

 

This was one of our two 'test build' engines back in early 2015, which we took to our (G3S) AGM that year, It's at about the same stage as your one in the photo & before we had the spring/axle/torsion rod castings finished to dress the frame with. They do kind of grow on you!  :-)

 

Regards,

 

IanT

Mine is one of the Impetus kits, it sits about 2/3rd completed because I decided on P4 for it...and its the only P4 that I have.  The last work I did on it was in 2012, when I spent 2 months in Norfolk Va in a hotel room...

 

(I was there learning all about UNREP/RAS, as I was going to be HMCS Protecteur's new RAS Deck PO, but never ended up back before the fire- so Derick kept his job...)

Could anyone please tell me the wheelbase of this locomotive and if the wheels are equispaced about the engine's longitudinal centreline. I have asked at the NRM but they're not able to help.

Cheers

I'd forgot- I have another Post War Sentinel, but it's kind of on the course scale style:
