Surface Drive Gif
 

This is an animation of a surface drive I created in AutoCAD. It is full 3D CAD work.

I hope this works

topspin can you send me the dwg file Id like to look at that it kinda cool how the drive is fixed in one axis and the rudder is movable

Looks like the rudder has enough leverage to rip the drive off the transom.

I'm not finished yet... the transom plat is getting bigger and the rudder is getting smaller..... the thing is the difficulty of actually making something like this and the turning it into a gif.

I do this in my spare time, so I can't practice much.

Post the .igs file and let us play with it (or torture it).

Here is a link to the .dwg file. Please don't splash it. If you make any improvements pleas e-mail them to

Cool! Nice Model. :)
I made the body transparent.

sounds doable, no skeg to guard prop not a good thing for the prop, But is a good thing for top speed

I have it in AUTOCAD 2004 right now 3d rotated
pretty neat Idea

check this out.. I had a little time after school and was just goofing around.

Well it looks like the page can't handle it... it is fine here on my computer.... I'll try again later.

that cad is some bad ass technology. wish i knew how to do that:cool:

Nice work Ernie, very impressive!
I hope someone isn't already splashing it.:rolleyes:

Ernie you using Mech desktop?
I have all the current ACAD Arch desktop 3.3
and ACAD 2004 does Mech desktop have more tools
for making the machine parts?

Check out this picture. You can see the surface drive that you designed in action at the website

N2Speed Website

KILLER VIDEOS:D

I called the guy at N2Speed about these surface drives. He makes them himself and they are very $$$$. The rudder is titanium.

I prefer the N2's trim cylinder mounting location.

Top, your tapered housing doesn't appear to have adequate diameter on the "prop end" for the appropriate size of thrust bearing packs.

My design was done for fun and is not meant to be functional... it is a tool for learning
CAD and I thought I would atleast design something that I liked. But since you guys are getting all technical I guess I'll have to design one that will work. I can't believe with all these critiques that you guys have not noticed the props concave the wrong way. :D :D

Oh and I use autoCAD 2002 I don't know much about any other design programs.

Ernie

course we noticed the props.
not trying to send a catalog of imperfections, only significant design conflicts.

and if you didn't want it critiqued, then you sent it to the wrong place.

2002? Bless your heart. You're spending a lot of time stitching together those 3D entities using that set of tools. Mech Desktop is a big improvement (but is still lacking in many ways). BUT, the goodpart is you are learning the 3D work from the bottom level and you will be a better draftsman because of it. When you get a powerful set of tools to use, you will be able to understand them and adopt them very quickly.

Now let's get some thrust bearings on that propshaft...

I haven't had much spare time this week but here are the newest creations. Another drive in 3D this one has more accurate measurements, bearings, and a u-joint that is built from dimensions of a real one. Stainless u joint 1.5" shaft size that takes 55000 inlb torque at 35deg max angle. that is 4583.33 and these guys are testing brake torque. If you don't understand that it means this little u joint will handle just about any powerplant you feed it.

No pic posting today. site isn't working right. does any one have the .dwg files for merc engines and stern drives? They are needed for my boat drawings and I can't find them.

Ernie

TopSpin80 cool drive . why don't we use some of that talent in the Uncensored section

:D :DGreg Maier that is a nice site . cool vids :D

pics seem to be working now??

here is the boat I have been working on
