Tunnelstuff in Norway

Hei!
Ser bra ut, dette. Setter det på «ønskelisten»…

Hey Joern,

Shiny aluminum looks even better in person
Been pretty busy with life and haven’t touched a boat since may, guess it’s time to get that 7.5 back together.

Class act sir, can’t thank you enough.

Had to stop the drooling, makes such a mess

I’ve just started making the molds for the new 91RS OB pipe

 

[Wasted wages]

Awesome machining...

 

[Joern Markset]

I received a new steering servo today, needed some proper power It’s gonna be interesting to see how it perform

 

[XtremeRcBoats]

That is some serious power.

Mold looks great. So you make 2 parts for the pipe and then put them together?
What pipe did you use for reference for the design or it is your own?

Yes there is 2 halves for the curved part, and then I will make a mandrel for the straight part. Parts will be joined after moulding and wraped in carbon.
When I designed the pipe I made multiple calculations in my pipe design software, and then measured a Prestwich pipe that I know for sure works good. Then I compared everything and made a final design based on experience and the measurements. If it does not work as I`m hoping I will simply have to adjust the design and make a new one. It is a lot of work, but that is how it is when making something new....

I’ve done something that has been rattling in my head for a while
I purchased an OS GT 15 HZ engine to see if I can make it fit on a 39 inch tunnel.
Since it as a gasoline engine I know for sure it is gonna be lazy Could be a nice Sunday-boat though

 

[Wasted wages]

Joern, Could you lay out the ignition components, and snap a few pictures please ?

I have two old gas motors that use a crank triggered ignition without the "flying magnet"
built into the flywheel... I'm interested to see how OS develops the power for the coil and spark.
If the instructions show the wiring and set up, I would love to see a picture of those too.

If it all works out the way I think it does, this could be a good source of parts to get these old motors running again!

Thanks in advance!!!
Frank

 

[Joern Markset]

It is easy to find on the OS website. 38170
You have to use a battery as powersource.

This is the tunnel I want to test with 15 cc gasoline engine.
Sketching on the gearbox right now.

 

[Wasted wages]

Thanks for the link !
This definitely shows some potential of working for me.. The current ignition system that came with the motors is multi parts, pieces, wiring, batteries, connects to the radio, has water cooled coils..
Very convoluted for what it is,,, this looks so much simpler...

Jörn,
You have made lots of good stuff. Have you ever made the exhaust adapter the other way?
Have an OS Speed which I would like to test the OS stock exhaust on.

No I have not made that version, but I`m sure it can be done. However, I`m busy at the moment, but can have a look at it later

 

[Joern Markset]

@anders-e It could potentially look more or less like this... I think...

 

[anders-e]

Exact, would be very kind of you if you take the time sometimes to make it.
There is no rush for me. I have the same climate as you have.

By the way, do you still have some CMB 45 adapter left?

Will ask my millingmachine if she’s up for it

I have good stock of CMB 45 adapters

 

[anders-e]

Hope she will tell you, yes do that, yes do that.

 

[Joern Markset]

I believe this is kinda close to what you asked for Or should I say demanded
