The new Stuart model - no7 V twin.
« on: May 09, 2018, 02:57:09 PM »
A few days ago some of us were discussing the new addition to the Suart engines range - a No7 V twin.

Their website has now been updated to show this, for the benefit of others who may not be aware here is the new engine :-

What's your first thoughts of it ?

Well I suppose it is one way to use up all the failed standard castings where the metal only fully flowed down one leg :)

Interesting to know if they made a new standard master pattern from scratch or modified a casting in which case machining allowance may be even less. If it is meant for marine use I would have thought they would offer the option of a disc type flywheel and reversing gear, 3.5" spoked flywheel sounds a bit on the small side. description of contents has now been updated and it looks like it is a cast boxbed.

Looks like the eccentric strap has one cast rod and the second one pivots rather than having two separate straps.

PS if you click on the image on stuart's site it comes up this big.

Presumably, the trunk guide castings are completely new to accommodate the bracing bar fixing lugs ? I still think it looks a bit flimsy and I'd have thought the inlet manifold could easily get damaged in a working model.

You raise an interesting point about a reversing kit, I wonder that will follow shortly.

I always swallow hard when I see prices for the bigger Stuart model kits.  But someday...

I won't be buying one  :ShakeHead:

At the price you could almost have a set of Gypsy Major castings :pinkelephant: Or a choice of any of the Alyn Foundry engine casting sets or perhaps two  :naughty:

Thought so, it's going to take a while until some rusty half made ones with bits missing find their way onto the market at the price you like to pay  :Jester:

Good point about a set or two from Alyn, though I fear the latest ones may not come with the special coating ;)

Jo - where do you go for a set of Gypsy Major castings?  Nothing seemed to come up when I googled it.

PS.  Is it just me, or is that blue elephant dying for the loo?   :ROFL:

Gypsy engine you say?  Sounds interesting.  Any links, as I can't find it on the engineer's emporium web page?

When did it appear? Too late for a April fool?

Even at a 1"bore, that Stuart twin seems very pricey to me. And to have to add the reversing gear? Nope, don't think so.

I hear that this "new" Stuart engine is at Doncaster today on their display stand.

Jo

P.S. The Gypsy Major casting sets should be there as well  :mischief:

I'll take a few photos just in case you want to assess its fondling potential  ;)

It may be pink to everybody else Jason, but I'm colour blind so it's a blue elephant to me as I see it, though now you mention it, perhaps there are some pink overtones in it.

Thanks for the Gypsy link,

Chris

There website has not been updated for ages, shows about 10% of what they actually do. Think they would do better having less full page adverts in the mags and use the money to update the site.

I believe it is the Reinhold Krieger  design, bit more detail on Model Engine NEws
