Martin Baker MB2 - From Scratch!

Recommended Posts

OK,

 

As I mentioned in another forum I have been inspired by some of the scratch builds I see. So, here we go! This is my first attempt. It combines many of the skills I've collected over the years. However, never to this level.

 

I toyed with Rhino. I didn't see any benefit over SolidWorks. I'm going to be learning enough anyway. I don't need to add a new software package to the mix.

 

I found some plans, photos and one card model on the internet. I've combined them in the CAD file. It's a little messy at the moment. I'll post pix once I get the fuse roughed in.

 

Here we go!

I am not sure yet. I have many new toys to play with. I have access to 3D printing, but the resolution is pretty low. I have access to SolidCAM and CNC machines. So, I may carve this out of aluminum and cast resin bits. Who knows? Then again, I might just go old school. It is easier out of the gate.

Howdy,

 

I'm struggling a bit with the loft... I'm shipping it to SolidWorks today to understand what I'm doing wrong...

 

I'll post more once I have something to share.

Having had the same type of difficulties not long ago with my Mystery Ship, maybe I can help somewhat. When you edit the lofting fonction, right-click and choose "show handles" in the submenu. The "handles" along the lofting lines appear as green dots which you can drag to other places. By right-clicking at the junction between a lofting line and a ridge, you can also make appear the option to "add handles " which you position on one lofting line then move to change the lofting. Strangely, I have also found out that trying a "frontier lofting" function after erasing an unsatisfactory lofting one will produce better results. Don't ask me why, I still have no clue ;)

 

In the same fashion, using a surface lofting function rather than a solid lofting one sometimes works better. You can then thicken the surface with the appropriate function.

 

Finally, divide your fuselage in sub-components between the frames. This will allow you to control the lofting lines and lofting handles better, and to add more handles.

 

Hope that helps.

Actually, the CAD work frustrated me. It isn't as easy as I want it to be: surfaces going all the wrong places... Ack!

 

So, I decided to build it out of card stock. I skinned it with a material that was too thick. It didn't work out.

 

The project has been put away for awhile now. It is starting to cool down outside. Time to put away motorcycles etc. I may try again during the longer nights we have coming.
