Have a play at "cadding it" yourself.....easier than paper drawings.
| | |
Hello
as a flight helmet collector (modern and older pilot helmets) it is hard to find certain parts because manufacturing ceased. While searching the net I got into contact with cnc manufacturing parts. This is a unique and fantastic way to make parts and the possibilities seem unlimited.
Unfortunately I have no CNC training or CAD programming whatsoever so I'm looking for a way to have a certain part manufactured.
It is a aluminium mounting bracket that attaches to a helmet. It will serve purely as a display item and is not functional.
I do have a lot of detailed high resolution pictures and a rough technical drawing. If modifications of the design are not too drastic I would be prepared to allow for some practical, time and money saving alterations.
Could someone point me in the right direction to have this part
(need 5 of them) designed in CAD and CNC made in gun-metal
colored aluminium ?
I'm looking forward from hearing a good solution.
Thanks very much and best regards.

I would suggest you post a price target, items like you want are expensive to produce in small quantities. Many a time someone thinks they can get something manufactured at a price similar to another item they have seen for sale, not realizing the other item was machined out of a casting 100,000 at a time. As an example there was a guy who thought he could get a couple custom boat props for a few hundred a piece, guys were quoting him $2,000-$5,000, the machinists wasted their time quoting and the guy got all bent thinking people were trying to rip him off.
Agreed, what is the highest price your willing to pay for this part?
Hi guys,
I want to start by saying I appreciate all the replies public and private.
The feedback and info is priceless for this layman.
The bracket I would like to have produced is meant for display and has no load bearing function whatsoever so when there is cheaper metal than aluminum this would certainly work for me.
Maybe simplifying the design a bit would cut costs dramatically ? For example : leaving out the two cylindrical rods in the design phase and only adding them after machining by drilling holes and sliding in the rods. Also the two side arms can be machined in one plane with the central core and only bending them in the right angle after the part is machined.
Just a question... could it be the original part was casted ? Being a layman I have no clue this is a relevant question.
To (finally) answer your question a price of 150 usd per part would be acceptable for me taken into account the simplifications and maybe other (cheaper) ways of producing.
I'm always open to suggestions and comments as this machining business is a very interesting niche (a large one) !
greetings
I'd say it was originally a custom extrusion machined then formed and finally anodised and reamed.
Casting would only be cheaper in larger numbers.......Volume is king.
Anodising being the trickiest part!
Might be tempted to quote if Belgian chocolate was on the table

Always nice to meet people who value the good things in life
We can certainly discuss Belgian Chocolates as trading currency.
What volume would you like (let me know in pm).
That's about as insulting as me telling you I want $10,000.00 a part.

The price he's willing to pay to have this part made...
I don't know, he is just uninformed. To the average guy $150 seems like a lot for what appears to be a simple part. Knowing it is a military helmet means the government probably paid more than that.
Ahhh the monumentally uninformed
