I was meaning overall height. Bottom is 3/4" plus 2" for the servo and more for your steering system, I'm guessing 4 " final height of hull?

Would it be a possibility to lay the servo on it's side and move the servo linkage to the top of the attachment below EDF and move the linkage between the EDF's to the bottom? That may reduce overall height by maybe 1 1/2 inches. Just a suggestion, I'm not telling you how to build your boat, just thinking maybe a lower profile may be easier to control>Comment

Ya I see your point. I will come up with a way to mount it right to the main bracket, inverted. That will bring the inside height to about 1.5" instead of 4.
On another note, I finally got to making some of the parts....
Here's the main bracket, still needs holes bored out for the needle bearings.
Here's the mount for the fan shroud. It's colored black so I can transfer holes for the clamping bracket that need to be drilled and tapped.
Here's the mount with the fan shroud on it. The posts in the last pic will be attached at the bottom, and will rotate in the needle bearings.
Here are the needle bearings, the posts that will rotate for the fan steering, and the bushings that will prevent the posts from coming out of the needle bearings. The stuff is made from low friction delrin.

1. Great work, I want to see it run!
2. what is Delrin??

I see, Just another fancy word for a fancy word for plastic, eh?Comment

yup, just a fance plastic as said above. I like it for 2 reasons...
1) like mentioned above, it's harder than most plastics. I personally like the machineability of it vs plastic, and when you tap it, it will not strip out as easy as plastic would.
2) we have it at work, lol, so it's free. Free is good.Comment

Do you do themachining at work?Comment

Sure do. I'm a PLC programmer but I have full access to a machine shop and all the resources that go along with it. I do all the manual maching myself. The shroud mount was cut on CNC, which was programmed by someone else. I have to take some time to learn to program it, then I can get REAL creative, lol.Comment

ever thought about making a service?Comment

I have done stuff in the past. But the time involved in manual milling really does not justify the cost. There's too much time in design, setup, and the actual cutting to make it worth while.
When I used to own a Tiburon, I designed beautiful 6" custom shorty antennas. Made a few manually which took about 2 hours each. Hardly worth the $35 I was selling them for. The demand took off, so I had a CNC shop run 200 of em. After annodizing, my cost out the door was $7 per unit. In the 2 months it took me to sell them all (still for $35) a chineese shop knocked em off and was selling em for $20. I got in, made my money, and got out just in time.
But back on topic, if you need really simple stuff that won't take much time, I'd be happy to help.Comment

a full scale reproduction of the 1rst lunar landing module, that shouldn't be too hard.
