HI Sean,

Chris is right, Ublox or similar helical antenna, must be vertical, or perpendicular to the sky, this is very important.

So you need to change that, even if the antenna exits the box through a hole(un obstructed view of the sky also important)

Ok, i dont feel its right to bandy money about on this forum, but.

I need a DXF/PLT of just the parts to give you an accurate cost, but in real terms....not much..

shipping to US for summet like that, about £4, as the machines run at 55meters a minute (and we charge by the minute), material costs are very low, a few quid at most. As this is a personal offer i would do it cost anway

So, if you want me to accuratley cost it for you, please let me have a DXF or similar with scaling.

Something worth thinking about is coloured acrylics, more expensive material, but weight for strength, this would look VERY cool as a 'homage' to DIYd

VERY nice SW work by the way....

I use a similar method for prototyping, here is a small preview.

Wings

Rear Fuselage

Let me know.

regards,

Mike.

Hi ZXO... would it be possible to get the DXF files of your case?
great job!

HI Sean,

Sorry wasnt being funny about the money thing, just we can take that to PM, if it works and you want to sell them, then as its your design then you have options.

Thank you for the kind words on the cutting, I have 3 Laser cutters, for doing diff types of materials, as quickly and cleanly as possible. After 5 years of laser cutting stuff,i still love to watch them go round. its like a little bit of magic :)

Anyway, i digress, email or PM the DXF part/outputs from SW and i will cost it up accurately for you.

sort one out, and see what you think.

Hope this helps.

regards,

Mike.

Sorry about being so blatant in my question. I was impressed with your cuts for your Hawker Temptest, and I was just looking for more of a ballpark of what something like this box would cost to have done.

Thanks for the reply/info

george and Sebastion
It does actually matter which orientation the ublox antenna is pointing. The radiation pattern is actually a hemisphere. This information can be found on the antenna manufacturers website as follows: http://www.sarantel.com/products/sl1206

I hope this helps

Dr. Mike Black, how much would you want to cut the design by Pieter van Woerkom out of the same 1.5mm multiplex? Shipping would be to Ohio, USA.

I can laser cut it for you, if you wish.

Its one of the things we do eveyday.

If you wish to see what sort of quality of work we do, please have a quick look at the lasing cutting on my prototype Hawker Tempest Mk5

Be good to do something different.

Hope this helps.

regards,

Mike.

P.S, not wishing to step on anyones toes here.
Pieter van Woerkom August 16, 2011 at 1:58pm

Me has a router :) Would like to reccomend building it from 1,5mm aircraft multiplex (like i did) leaving room for 2mm deprom dampning. I allso lightened the box by opening te walls.

@Sebastian

Thankyou kind sir for the info!

@Avalerion

Maybe try ponoko? It's a bit large for my makerbot.
Avalerion August 16, 2011 at 1:12pm

Any ideas as to where one could get this built…?
