No fuse too fat

This morning I popped off the layup we did last night on the Tyhpoon. It came off perfectly clean. The PVA peeled off in one piece like a piece of cellophane. Will have some pics up in the Tyhpoon thread tonight. Time to start working on the canopy!

I popped the fuse we did last night and this one is best so far, so morri is on a wait and see for his.

Hey guys,
I was just checking out Hamburglars thread. I think he is using something like this.

I'm also a machinist (and many other things, but that's for another day).
At first, this looks like a great price, but something wasn't right.
Digging further shows this:
Manufacturer Suggested Retail Price :3899USD
And shipping is also $900
Also this: Spend $899+ & get 18 months financing
Subject to credit approval.

So far the cheapest router I found is the Phlatprinter:
Which is good for sheets (wood, foam, soft metal) and basically 2D plus some Z.

As you see we're not talking about the same thing. So if this really goes for $882 (even plus $887 shipping) it seems way too good to be true, just the parts alone cost more (VFD, spindle, ball screws, step motors). Caveat emptor!

For 3D printing there is a printer in the $1000 I think (from memory) limiited volume (like 6" cubed or so).

Feel free to ask any questions. If I don't have answers, I know people that will.

Shipping is pretty high and I think you would outgrow this machine quickly. The workable area is 12"X 23"Y and 3"Z.

Yeah, I noticed the $900 shipping after I posted. F'n eBay crooks. The reason I was interested is I have TurboCad 14 Pro which is supposed to have full 3D capability (unlike the Deluxe version). Problem is, I don't really know how to use the 3D stuff yet because I haven't really had any need to spend the time to learn it. But if we had a 3D printer or router, it would definitely be worth while.

CADs usualy output STL (Stereolitography, or 3D printing) files or DXF (Autocad format).
Then you need to use a CAM software to work out the machining. It will set the sequence and so on and output a Gcode file.
THen the Gcode file is fed into a machine.

3D printers do plastic from scratch, but small for the time being (and price)
CNC Router do mostly flat stuff
To do a wing mold (which is my guess as what you're interested in) takes quite a big machine. And it has to have full 3 axis capabilities (all three together).

Don't know turbocad, but I use Sketchup (free and completely user modifiable). I do all my designs (3D) and layout for cutting foam with it.
I can output any airfoil from the data set, and modify it.
There is also software to test airfoils and wings.
And of course any template or sections can be printed from there.

I can show you guys anytime and help with needs.

Would love to see a demo, Michael. I have played with SchetchUp but did not dig too deeply. It looked to me like it was geared more to doing straight extruded shapes like rectangles and cylinders. But like I said, I didn't spend a lot of time with it.

I'm interested in doing both wings and fuses. Maybe a home build kit? Not sure what the total investment would be though. This one says it has a 48"x48"x5" work area. We could probably get away with 48"x24"x5" for what we do. That way the machine would not be so gigantic.

Hehe. Yeah, but I'm trying to build the canopy for the Typhoon right now and there are no straight lines to use as a reference and I'm *REALLY* wishing I had this.
