I'm going to be building & trailing a new 90mm hybrid motor soon, that will end up being around the high L class. I am wondering if anybody is keen to have the parts for such a motor as I can place an order with a CNC shop for a bulk run.
PM me.

90mm Hybrid Motor
Space is only 100km straight up, see you there 

The big problem here is insurance.
Anyone running a business just can't produce motors for the hobby because they simply won't get product liability insurance.
Drives me nuts! I'd have 20 different motors designs, all extensively flight tested using , 4 different ignition systems, impulses from G to M, but there's just no way to get them to market.
If anyone disagrees ,and would like to manufacture and sell them, then I'll be more than happy to do a deal....

You don't tell the machine shop what the parts are for. Just give them toleranced drawings of the individual parts and ask them to make it.
Are the parts you need just turned or are they milled as well ?
I would be interested to have a look at making the parts but I'm not in a position to resell complete motors.
If you are keen let me know and I will PM you my phone number.

VW-engines also manufactures Aircraft engines and is about to get a tender to be Australias first (i dont know of any other) approved rocket manufacturer. This is all depending on TRA approval for each motor designed. They can manufacture any type of motor from hybrid, liquid and composite motor parts.
They have a good relationships with CASA as a experimental aviation company.
just contact me or vw-engines.com

Machining isn't a problem. I own a CNC lathe and anodising tank( When I say "tested" I mean hundreds of tests, most of them instrumented.)
Interesting to hear about VW-Engines. I'll give them a call. I don't see CASA or TRA as the real issue though. As I've said, its the insurance companies that hold you back, and you do have to tell them what you are doing. Same goes for importing, someone gets hurt and you can loose everything..

all turned, there is some off axis drilling, but it's really simple stuff.

My plan was to simply facilitate a bulk order of components and pass them on to those who wish to build their own motor..I had no intention to do so as a business. Any hardware would be EX and thus not certified by Tripoli etc..
I had limited response to this post, so I am simple continuing with my own 100mm hybrid. I'm pretty close to having it test ready, so when I get it on the stand I will post some results.
Cheers
