Started running-in Brunel!

A very popular starting point for Live Steam. With their low cost comes a number of problems which can be discussed here

Started running-in Brunel!

Post by Bill/Rubery » Wed Jul 02, 2014 11:33 am

Hello, Finely started to run in Jakarna....my new Brunel. The exhaust pipe is a bad fit in the engine body. Has anybody out there soldered the pipe on?? Found loads of loose bolts...most of all the large nut under the engine by the rod out-let! Using the old Brunel as spare parts. Had to go back to Mamod as major leak in sight glass at bottom. Peter (the nice chap in the back room) told me where to buy the spare glass tube from....

The reason the exhaust isn't soldered on is because Mamod don't know where the customer wants it to be routed. Ideally it would go down vertically and then vent onto the track (and you'll see there's a cut out in the floor to accommodate the pipe). Others have routed the pipe so as to come up on the side of the chimney or even into a condenser to separate the waste oil from the steam.

and of course some cylinders had a single outlet for the exhaust while others came with one on either side, so you're left with an even greater choice.

Personally I've opted to route the exhaust down onto the side of the track. Not prototypical but it does keep the engine cleaner.

and yes, you can solder the pipe in position if you feel you're able to.

I am going down the condenser route Mike. There are quite a lot things one can do to make a locomotive freelance.

You could make the condenser the full width of the loco and use it as a seat for the driver as well, a bit like the Regner Willi.

A nice hot day and a day for starting running in properly of Jakarna. First a praise of ordinary household mastic as I fitted a 3/4" size pressure gauge as the factory fitted one is rather gawky.....way too large even for 7/8" scale! Lots of steam leaks from gauge pipework but the mastic fixed them good and proper. The steam-up bit of my line is about 18" off the ground and allows me to view the gas flame on the burner. Just as well I painted calibrations on my gas valve body and regulator body as I can see how one has to only open the gas valve a 'smiggeon' to light up and wait a bit for burner to warm up. What with the boiling water injected into the boiler the water heat hit 25 ibs in no time at all! The usual palaver turning the fly wheel to clear the condence and off she trundles. The lower gearing certainly shows as a half revolution of the regulator gets around a 'scale' 10 mph and the hills on my sunk track-work did not stop Jakarna at all. Two good runs.....15 to go and she will be fine!!

Sorry Mike, just noticed your reply. I hope to fit a condenser by the side of the gas tank in front of the locomotive. The cab part at the back is going to get a half cab like my Roundhouse 'Millie'. The company don't like the staff to get too comfortable so seating is in the air at the moment.....

Anybody know how to get the steam control nob off a Brunel? I want to get mine off so I can have a regulator handle on like (say) a Roundhouse one. When I undo that locking nut on the top of the regulator housing and turn the nob it comes out a bit then just turns endlessly! Bit of a laugh running my newer Brunel as I go into our house and leave Jakarna running along I know that the loco will still be trundling along when I return....if I did that with my rod locomotive something may have happened to the running whilst I was away....

If its the same as a Mk11/Telford (i.e. has a large rubber ring around the perimeter of the regulator knob) then its quite easy.

Unscrew the locking nut like you have done.
Rotate the regulator knob anticlockwise until it turns very easily. At that point its just held in by the internal O ring.
Then continue to rotate anticlockwise and pull back at the same time. The regulator shaft should come out of its housing.

The knob itself threaded onto the shaft and then soldered to stop it unscrewing.

Busy Bodies 'Brunel' Figure

Post by Chris Cairns » Mon Sep 08, 2014 5:37 pm

Picked up one of Rob Bennett's 'Brunel' figures at the recent Llanfair show.

Image

As you can see he is not 16mm scale being taller scalewise than his actual 5' height.

The other figure was a clearout from Modeltown - probably an ex-display 7/8ths figure as he still has glue on the bottom of his boots.

The Model Town figures are a bit primitive but get you 7/8" scale figures cheaper. I buy just the bodies as I have a number of fine scale heads from other figure kits from Back2bay6 left over. The result looks very good as well. I don't really like the caricature type of face's.
