Stingray Build

[RCnut]

Couldnt resist, taped all the bits to see what it looked like. Not bad for three weeks work. But then if its a subject you really like it goes like that.:biggrin:

Would using partially spiraled vanes on the inside of the ratemaster get it to spin when its got water being pumped through??

I am so loving this thread!!!

If the jet outlet was as large as the inner diameter of the ratemaster it might work but its not so I doubt it, In any case I want to make the ratemaster work independently of the jet and possibly use it as it was intended, a contra rotating eddy damper.

What kind of holding fixture or jig did you employ to hold the smaller tubes around the bigger one? Great stuff!

I drew a circle to the inner and outer diameter and then drew lines across at equal intervals (with rulers and such) then took one of the tubes and marked the curve in each segment, this was then dremalled out and the complete ring template glued to the larger tube then the smaller tubes were glued into place and the gaps filled. Its by no means a perfect way of doing it but its turned out very symetrical and when spun round it does not wobble, which was my main concern.

Today I added the end bit on the Ratemaster and the front ring was added to as well. All I have to do now is make sure its 100% perfect and then wrap it in cotton wool, lol.

the ratemaster which I will attempt to make spin as well. I have an idea how to do that, perhaps a ring spur gear on a small pinion. but thats for later.

Its definetly taking shape. A Pleasure to watch you sir.

[RCnut]

Today I did the ratemaster, One big tube with 16 smaller ones around it cut down and angled a bit. heres were I am with it.

[RCnut]

Will do Sir.

Seriously tho guys, I do get to spend a lot of time doing this, so I'm lucky in that respect.

Your speed is matched by your quality. It's a joy to watch. Keep those post coming please.

Yesterday and today Added a feature that I thought would be nice, I made it so the cabin section Sits inside a recess. Much like the old Wave Stingray kit.

[RCnut]

That was my understanding, but as you say mines a different scale so I'm on my own, lol. Its just one big pipe with lots of smaller ones around it, How hard can it be?
