Jedi's A-10C home made cockpit

I have a friend that was trying to look at it autocad 2009, and he could not open it up either. Since I do not have a cad program, I downloaded draftsight to view the drawing, which works great for me.

Yeah, my multiple e-mails have all followed up with me stating that they cannot open the files as they are corrupt and nothing shows up.

One recommended an .iges file?

Can anyone convert this?

I tried to do so but AutoCad will not do so. I am running 2012 btw for reference.

Wierd, of course my brother had some work on this file to trace every piece to be sure that all lines were closing, that all the pieces with the right thickness were on one sheet and to point were to cut but that's it.

Jedi, do you mind sending me the files one by one? It could be a problem when you add them to a zip to compress the size.

I would if i could Ryyy but it is only one file.

I have send it to you now unziped, hope this works.

Gr, Jedi

I save the file in autocad 2010 that can be the problem.

Here is files for autocad 2000 and 2004 and 2007.

Hope this will help.

I have done some dimensions to help you guys.

Btw, this week i changed the hub height, put it up for about 2,5cm.

Now i have more free movement so please keep that in mind when you are copying the plan

Jedi, if the drawing in that file is "finished", I would be happy to go through it and add the necessary features to make it simple to toolpath for CNC. Things like putting dog-bones in the corners, etc. I can also optimize the material use to get the most out of a standard 4x8 sheet of material. I use VCarve Pro v6 for all of my CNC stuff and it's got some fantastic nesting features for material optimization. :)

That would be great geneb, thanks for the offer.

The drawing is finished except for the higher stickhub.

I will change this next week and upload the file again.

I can wait until you get the drawing updated - just ping me and let me know when it's done!

g.

Tanks for the quick dims Jedi. And Gene as usual thanks for another step in the crazyness of pit building.

x2 for Gene. Thank you so much. Let us know when you can e-mail us some files.

I went ahead and processed Jedi's earlier drawing.

I suspect what was really screwing with people is that the drawings are 3D parts that have been simply laid flat, not turned into true 2D drawings. I exploded each part, deleted all the "extra" data and then re-joined each one. It took quite a while. :)

I've sent the optimized DXF files to Jedi for checking. Material requirements are three sheets of 12mm, one sheet of 18mm (a VERY partial sheet) and one sheet of 6mm. Each sheet (except the 18mm) is 48in x 96in.

In order to cut these on a CNC machine, the vendor you go to needs to use a 5mm bit or smaller. This was a requirement in order to make the proper t-bones for the 6mm material. (a 1/4" cutter is 6.35mm so can't be used here)

Once Jedi approves of the drawings I'll make the optimized DXF files available as well as the CRV files I produced in VCarve Pro. These will be CNC ready and your vendor only needs to load up the files in VCP and choose the output processor for their machine. I suspect they may want to check the speeds & feeds for their setup as well. The tool paths in the CRV file will be created using a 5mm end mill. The lettering tool paths will require a 1/8" FEM cutter in order to give a good and smooth pocket. Both cutters should be downshear. (this helps material hold down)

I've updated the stick hub by extending it 25mm.

See the attachment for details.

For those that want to see what the drawings look like, you can grab them here: http://www.geneb.org/a10/optimized-wharthog.7z

These are just DXF files and have not been updated with the new stick base height change. I'll try to get these updated and posted with the CRV files this week.

Outstanding!

Geneb, again, thank you for the help. I really REALLY appreciate it! I know this must take lots of time on your end, so let me know if you need any help with anything. I'd be willing to donate if need be as well (:

Ok, here's the file:

http://www.geneb.org/a10/optimized-wharthog-v2.zip

This file contains DXF files split by material thickness and optimized for cutting from a 4x8 sheet using a 5mm cutter.

I've also included the VCarve Pro files that were used in the material optimization step. I decided against providing any tool paths as individual operators have their own way of doing things and can easily generate the tool paths for their machines the they want.

Enjoy!

Thanks again g

Is there a program I need to view DXF Files?

You can download DraftSight from here: http://www.3ds.com/products/draftsight/free-cad-software/

Thanks again g

You're quite welcome! Happy to do it.

Thank guys for this great project, what a beauty. But am I dumb as I can't see any measurements in the DXF files opened with CadStd? Or are these in the .CRV files?

Henk, there are no dimensions in the files I provided. The files I provided are optimized for material usage for cutting by CNC machine. Jedi's original drawings contain dimensions suitable for hand layout and can be opened with DraftSight.
