Bowman Eagle gas burner finished.

Hi,



Finished the gas tank  for the poker burner previously made.



Turning the copper tube for the tank.



Flanged end fitted into tube.



Hydraulic test of hard soldered tank.



Tank finished and painted.



Testing with poker burner attached.



The poker burners are a push fit so can be changed.  Photograph shows the new tank firing a small burner made for a locomotive.



Tank and burner installed in hull. The burner uses the same attachment as the meths tank to hold it in the hull

As both local lakes are empty it looks as if it will be sometime before the Eagle gets a run in open water.  First it will get tried in its test tank/box to see how the gas burner performs.  I know the meths one makes enough heat OK.  So that's it, other than the test in a lake.  The other two Eagle hulls with their engines have to have boilers and burners made to finished them.

I have finished the three stationary engines that I was going to do over the winter.  A chimney has to be made for the Mersey and I have resigned myself to turning it from the solid, a bit of a waste of a 1" brass bar still it will finish it.  So it looks as if it is back to making and maintaining small steam locomotives. It might be some time before I will be doing anything relavent to the group.

There is a busy weekend ahead.  Playing trains in Exeter tomorrow a very early start to help set up the layout. Sunday our local model club is open so its playing trains again on their GR and on both days there is a Cardif Model Railway show on. Its tough be some one has to do it.

Come next week, its away for a couple of weeks, relieve all around!.

Regards Tony.

That is a clever construction that looks very stabel

How did you make a refilling valve for the tank.
good stuff.

I love that burner.
I must one day learn how to make gas burners.

That's very cleverly done.

Its a filler valve from a Ronson gas lighter. Cost 3/4 from Chuffed to Bits.  Thread M4.5/0.5

I love the ability to change burner size, awesome job!

You have done a nice job on that Tony and gas should keep it looking a bit cleaner and you should have better control raising steam too.

Tony, what are the solder/build/pressure requirements for gas burners. I have seen a kit on ebay to supply the copper and endcaps and wondered about making one safely.

I know the fittings are also available from places from forest classics.

Great work Tony

I was told by a former manufacturer of them that a Hydro Test to 350 psi was required.

Hi James,
The model steam boat people suggest a 320psi test for tanks using a propane/butane mix, it is a lot lower for butane only. I can look out the exact figures if you wish. I don't think of any requirements for the burners exept for hard soldering them together. The tank as made for the Eagle has a stay connecting its two flat ends together for strength.
Regards Tony.

First run of a Bowman Eagle Copy on a lake.

Hi,


Having returned from far away places yesterday and just about over jet lag, today I had to work and when returning  home from the job I drove past our local lake.  While we were away the lake had been filled! The weather being very sunny I decided to give the Eagle its first outing on a lake. Arriving home I fitted and checked out the R/C having first fitted some plastic bags over the battery and reciever as suggested by members of the forum.



The gas burner which hadn't been tried in the hull before was fired up and it provided more than enough heat to boil the water in the boiler.



Back to the lake with a still warm boiler which was fired up again.

Video.



I think the results are quite good. With the weight of the gas tank, burner and the R/C, the Eagle is a little lower in the water. I think its speed is OK on a boiler pressure of 12/15psi.  Its turning circle of about 8 feet which is managable. All in all I am very pleased.

Regards Tony.
Les

That goes really well, you must be well pleased.

As a former owner of a couple of Snipes- that my friend actually earns the name "Speed boat" which neither of mine ever approached!!

I kid you not-she is the best running "Bowman" I have seen run on the water- fleet of foot.

Please feel chuffed for about a week--or every time you see it run!

Fantastic stuff - very well done on a superb looking (and running) steam boat. Thank you also for all the great posts on the build.
MrDuck

I half expected that poor swan to be rammed in the rear

Great going there Thumbs up!

Looks fantastic - which lake is that?

A splendid boat made with talented hands!! Old man Bowman would shake your hand for sure!

Nice job on the burner, Tony!  I don't read the boat section often.  Glad I caught this one.

Very good idea Tony, and you have made a very good job of it as well.

I'm late to this thread also. But I also want to add my congratulations for a job well done. The gas tank is a work of art!
