I'm back to working on the plug. When its right I'll make a new mold and then you can all have one!

[HardRock]

Doing some wotk on the control surfaces before I put this to one side. And also struggling with posting photographs.

I have no idea why the first photo is a different size to the second. Same photo, same process = different size. ???????

And of course the photograph that I was least concerned with has translated itself into the biggest image. Naturally.

[He Who Shall Not Be Named]

You got that thing looking just fine -- lots of good work on display there, Hardrock. As to photos to this site: What a pain! The only way I can get good quality, big pictures up on this forum is to use an outside 'host'. I just started using photobucket and once I learned how to upload to that server and pull them down to my forum of choice, no problems.

Any attempt to upload pictures from my CPU to this forum has been met with failure. What's up, Mike?

Reduce the resolution of the pictures to width 1024 x height 768 and reduce the file size to app 130kb that you do by adapting the dpi of the image.

Thanks Bart. I'll give it a go - and I just noticed a few things that I got wrong.

Calm down. I've fixed it. There is a handle on the hatch at the rear of the sail and quite a lot of red primer showing through the back top coat. All done. I'm working on the SD today.

[HardRock]

I've been working on a simple SD for the Piranha. This one will be a dynamic diver but I have ordered some larger diameter tube which will go around the outside centre of this SD and which will be completely sealed. I'll run a small pump at the front of the sub to force water into the sealed tank. Internal pressure will only allow a realtively small amount of water to enter the tank against the resistance of the increasingly compressed air inside. I'm hoping to get enough water into the thing to take the boat to submerged trim. The pump will have to run continuously which will kill the battery in less than ten minutes but I'm prepared to put up with that at the moment.

The SD as of today. Ready for the pond.

Can you post a close up of the internal layout of your wtc?

BTW, Which way did you go- bow or stern planes?

[bwi 971]

Can't you make a pinch valve? When you activate the pinch valve you can stop the thirsty pump?

I'm going for small and simple.

Fixed stern planes, working bow planes and working rudder.
