something I put together recently, 2 Jensen #5's joined by a common boiler , with separate throttle controls...

Nice setup Bruce...it's up to the SPS standard we've come to expect!!!  Is it destined for eBay ?

Another great build Bruce   

That gauge sure dropped fast when they were both wide open, but didn't take long to build back up once you slowed them down.

thanks Nick,
any Jensen boiler even with a single engine will lose pressure quickly under WOT ,I was surprised by the fact that at idling speed these engines are quite efficient and with the voltage reduced, I can get quite a long run time out of the one fill up

A very nice build Bruce, works well in the video!

Shame Jensen no longer offer the #5 as i think it is much more attractive than their current double acting oscillator engine.

Yep ... that beautiful lash-up has SPS written all over it!

Well done Bruce !!!

Bruce you do a great job on those Jensens that you modify.

That's a nice build Bruce and runs surprisingly well off the single boiler - will be watching it on Ebay. Just out of curiosity is the pressure gauge base/double steam feed lines setup difficult to make?

No , not really Larry, since your joining 2 engines with one common banjo hub, one has to go....generally you can twist them off, sometimes you have to de:solder them, actually both need to come off because you need to drill straight through the "keeper" for the other steam line to join into, then re:attach & solder, you also must flip the left hand engine around, on a Jensen #25/75 its just a matter of unbolting the steam chest, flipping the engine around & reattaching it. on the Jensen #5's you might have to de:solder the steam line from the steam chest...flip 180 degree's & re:solder, or if your lucky it may just twist around for you.

Love it Bruce!
