Yippee!

It floats!


It floats! though 3 weeks ago, I nearly sank it. Testing the pumps and one of the feed tubes ruptured. About 30' out I noticed it listing to starboard and sitting low. As cool and composed as I think I am, the adrenaline kicked in and control buttons were pushed and pushed again. I finally did manage to get it back close to shore so I could step in and shut off power. Boy! this stuff is fun

After returning several pieces of electronics for various repairs, I was able to test all systems this morning before setting sail.

Everything works!!!!

LA Fireboat 2
1/32 scale, 40" long and 10 beam, powered by a pair of Graupner VSP drives, Tracker 3 radio with a Switch8, 9 months to build and too many $$

Jon, Great build, but think, where else could you get more bang for your bucks. Nine months of enjoyment building, designing, and anticipating getting the boat on the water, etc. Now you can look forward to many years of competing or running the model. That is the rational I give my wife and it works part of the time. Again, great looking model. Get us some photos of it pouring on the water when you get things all worked out. Jerry J

I worry about that too, the urge to pump tons of water is inherent to building that boat.

Nice to see a finished version of the Fireboat.
Looks great, congratulations!
Guess I should get back to work on mine...

Boats on the brain!!

That's what I like to see, all of the monitors working at once. There are so many boats that I see that will have only one monitor working. You have made that boat a work of art. Take a look at some of the fire trucks in the toy department for ideas, some of them have working ladders. Heck, put a working monitor on the end of the ladder.

Thanks for the kind words and the help over the last several months.

>Umi - I first used 1/4 surgical tubing but after the rupture I changed to clear plastic I found online.
>Ropanach - the 5 monitors operate separately on 4 pumps.
>Ghost 2501 - good idea! ;o)

Hi Keith - reading your other post with the Mr Darby conversion - I still have to return your photos!!
The Nanuq runs - watching this to see how the best way is to build monitors and which pumps work well.

>Mike - the pumps are Delco windshield washer pumps from a salvage yard. More pix available at:

The monitors I built from 3 different sizes of brass tubing, and a small plug with a hole in it for the stream. I kind of followed what Aimee outlined with the pillow mounted for looks only.

Thanks for the info and web address - I remember looking at it some time ago and forgot about it. I don't think I'll go with that many pumps but will experiment. Any idea if the Robbe monitors perform well?

Mike, if you want some solid castings of the SKUM monitors, I can send you a couple solid pieces. You could then carefully drill out a channel, and then plug the ends of the drill holes to route water through it. The jewelers wax I ordered has yet to come in, and at this point, I am thinking of redesigning the mold. The next monitor mold would allow me to cast it in sevearl parts that would create the water channel once assembled. Let me know if you want one(or two).
