    No they have not got back to me ( thats ok still waiting on tax return which is being held till oct ).

    But I did get a new 690RR Fairing a really good copy gel coated with carbon kevlar reinforcements just needs a quick sand and paint. then its bling time
    I'll get the Nav tower aniodised or power coated and re-do all the wiring using one of the fuse blocks shown on this thead . As it is a clutter of wires there .

    Yup, that's them just "Dominator" or "Street fighter" twin headlights where are DOT approved and high/low beam and the wiring just plugs into my WRR!

    I used a set of them on an old DR650rs, and I thought they put out the most pathetic light I have seen on a road going bike.

    Looked good, but I would prefer to see good at night...

    And I seem to do a bit of night riding.

    After getting of my 640, I am amazed at how much light my wife's ZZR250 puts out, but I don't think it would like being run into rocks or having roost thrown at it...

    More out of curiosity then anything else, I figured what the heck.

    Seems very rigid vertically and gives nicely side to side. Taking it for a ride this afternoon.

    +1 on the cool and a great way to use tis type of material! Definitely interested to hear ow it holds.

    Can you load it with some more weight then just a gps while testing? Roadbook, icos and gps unit with plate do weigh a lot when combined.

    ...Now wondering of to find my hack saw and start comstruction too :)...

    That's indeed a very nice setup :clap . Use of new materials is always nice ... :freaky

    HDPE is third on the list for my setup at the moment but I will sure try it ... :evil

    Interesting.

    Could you elaborate on why you switched from aluminum to HDPE?

    To try something new as I read it.

    I'm seriously asking myself too. There is no selling point on using HDPE besides cosmetic. Mecanicaly speaking, it's questionable.

    This thing is a job for 6061 T6. You want it white ??? then have it powder coated white ... :deal

    Heres a quick blurb from the web in regards to HDPE and Acetal (which is similar to Delrin)

    Key Benefits of HDPE Sheet and HMWPE Sheet:

    Very low co-efficient of friction
    Very high surface release properties
    High chemical resistance
    Excellent impact resistance
    Very good damping properties
    Weldable plastic
    Excellent abrasion resistance

    Acetal is the product oggy knobs are made from, pretty strong stuff.

    Applications of Acetal Machined Parts:
    Precision gears
    Bearings with close tolerances
    Electrical engineering insulators
    Compact bearing assembly
    Snap fit assemblies
    Parts which operate in water between 60 to 90;C

    I'd think they could both have great uses with nav towers. Great to see people using it.

    In a crash situation I'd think HDPE/Delrin etc would result in a better outcome for the rider? But who wants to put there hand up to test it :huh

    Serioulsy PSI of HDPE is nothing (5K PSI ???). You can barely make filets out of it. Forget about Heli-Coils. PSI/lbs is pretty low compared to 7075T6 or better 7068T6 (100KPSI+). Number of cycles for 7075T6 at 25000 PSI load is more then 500,000,000 cycles. Which is many orders of magnitude higher then HDPE.

    I see a good looking device. But in this case, "Innovation" is a word that one would hear from the marketing departement. Not from the engineering dpartment.

    I don't know how all those numbers translate to real world use, so I'll defer to the guy that's actually willing to try something new and test it out. Typical engineer, always running to what they know and running away from anything new. Show us your nav tower:lol3

    I think you are making too many assumptions about the Design. The weight of the system is being supported by a massive chunk of 6061. For these plates to encounter the forces you are talking about they would have had to suffered a massive impact. None of the nav equipment would survive, forget the rider. The deflection that the HDPE would offer might save the nav equipment in a crash.

    It still has the top backbone bolted to the top triple was my guess right?

    It looks like it. You can see it the the top picture I think. The backbone is robust, to say the least. If I break that part in a crash I really don't care what happens the rest of the bike, I just hope the helicopter that is coming to pick me up is in good shape.:lol3
