Looking Good Piet!

What kind of reversing does it have?....swing eccentric?

Dave

[piet schuurs]

Thank you Dave

Reverse is slip reverse. I think thats the same as an swing reverse?

It works, but thats it. Its taking to long to reverse this way.

So, first sail this summer and looking what the faulds are. Then during the winter Iám going to try to make an SLR on her.

For exemple, I have at an alternator on the proppellorshaft. But the shaft rev. are to low.
So I have to fit a smaller pouly on the alternator for more rev's.

I'll think during the summer there is coming up more to do.

There always is! But remember the reason we build these boats....Man created boats to keep their engines dry!

Looks great Piet! Much nicer than my boat.....

Congratulations!

Much nicer than my boat.....

Iám, not agree, Dave. They are almost the same but they are just different, its just a matter of teast.
Rushforth looks great!!!!!
And if I look to the plant in Rushforth, Iám jealous.
Mine is a mess, your looks thight and professional.

Your a fine man Piet A fine man indeed.

OK, So When is the launching!?......and more importantly the party afterwoods!

Ohh and we want video.....says the pot to the kettle

Your friend,

Dave

Oh and this coming winter, when you make up the SLR, let me know if you would like some help drawing them out....I'd be glad to help.

[piet schuurs]

Heh Dave, we have almost the same boat and both have a compound. Than we must both think about the same way about a launch, dont you think?
Regarding to the SLR. I'll think I start to copy and dubble the origenal excentrics ( the must be right the way the are now ) and lower valve rots.
The new timing, and the link between the two lower and the upper valve rot are my proble.
Thats difficult to figger out for my, a aspeccialy the lenght of the link.
Maybe you can help here, without writing a hole book on this forum.
There are lots of pictures or drawings on the web, but all for one specific engine.
Is there a formule for this?

I like your offer Dave, lots of thanks for that.

There are as many ways to design valve gear as there are books about it. My suggestion is to talk to someone (preferably in something close to your language). I'm acquainted with Rainer Radow who did much of his own engine design (Dr. Eng.). You can find him at http://www.steamboating.de/radow.html and I'm sure he will be happy to help. Tell him I sent you.

Hi Piet,

The length of the link should be about 5 times the throw. Based on my own research
That is what I used when I designed my engine.
I would start with getting the valve events, as they are today, documented.
You can do this with a piece of paper and a pencil by doing a rubbing. From there, you can measure your ports and establish the events.
I would also suggest you run a brake test of the engine as it is today. Then there is no guessing later.

For small engines such as ours, I would keep you exhaust lap small or none at all.
Ray Hasbrouck swore by this.
