Thanks, so I'll probably buy some moulding foam and make up a tail section for the rear of the cowling like you say. Do you think it needs to come...
I'm a litle worried about putting a cover over the boat, as both the copilot and pilot need to move around to balance the boat, there are no...
Finally getting somwhere with the CFD. Took a long time to get a solid model in Rhino which I could use. Cd, drag coefficient is around 0.438, now...
Sadly it's not really possible to get the co driver and driver in line, the engine is tiller controlled but also we need to sit side by side to...
Bit of an update. I was down at Coniston last November at records week, managed 70.10mph average over two runs, max speed of 74.9mph. Super happy...
What you say definitely seems to be the general concensus from what I've read online. The design is now fixed, but as it has relatively thick...
Yes you are right, the range of yield and tensile strengths for stainless was very large. But as far as I know props are made from 316, which is...
That's what I had decided looking at HTB1, which is brass. But NiBrAl is aluminium bronze, for example AB2, which appears to have superior...
Regarding material, does anyone have any experience with Aluminium Bronze/NiBrAl? Seems a lot of companies prefer to offer this for casting as...
Project is coming along quite nicely, I've just about finished modelling the modified propeller. Having some problems just now naked edges on my...
The main purpose of having one 3D printed, at this stage at least, is just for display - we have to do a presentation once the project is...
I'm looking to get a 3D model printed once I've finished my design, anyone have any knowledge on different forms of plastic? Generally available...
Attach the blades to the hub, but the exhaust gas also flows over them, so I figure if they are angled then the exhaust will be propelled out and...
No it is staying rubber hub. I'm not reinforcing anything, I'm trying to modify the blade geometry from the original so it looks more like the...
I'm not removing the exhaust hub, it's remaining a through-hub exhaust propeller. It's a propeller from an outboard, which I am modifying, but it...
