Just the 2 squadrons and the roadbook/USB circuits, need some smaller fuses,

It may have been asked before but can you give me a link to the outer sheath (black) that you have used, It really neatens the front wiring. Also about the fuse holder too if possible.

Is certainly possible to have the best of both worlds, and it has been done. Try to find some images of the old Baja XR650's with dual 8" racelights. They were frame-mounted and tied into the steering. We're working on adapting that idea to smaller LED lights now.

Or you can just wear a helmet light. On the ice at night, I wear the helmet light and I use it to look through corners, while I'm sliding and the headlight is pointing off the course from counter steering. The helmet makes a nice back up if your lighting quits.

The wrap looks like powerbraid...McMaster looks like they have it for pretty cheap

Working on the first iteration of a tower for the WRR. Still need to add in various switches/work on packaging/lightening, but it's getting there. Looking forward to seeing how light+rigid I'll be able to make it with a bit of FEA

godwinmt nailed it, that's the series I use, comes in colors and sizes.

Connectors I get here now, they're US based for me and ship fast.

Fuse holder I picked up here, they also have the connectors, so you can combine your order, but take a bit longer to get here,

Hey Jesse, they still have them, kind of pricey and don't break it in a race, all the force of an impact is transferred to the strut. I'm with Aaron, a big fan of helmet lights. The LED ones are super bright, last longer then HID and getting lighter all the time.

Nice job on the design, if you have a decent FEA plugin use it, they're magic and can save a lot of time and grief.

[godwinmt]

It's amazing what FEA used when smartly can do...and what it can screw up if you don't know what you're doing :) Inventor interfaces with ANSYS very well which is a blessing with it all.

Is this some kind of steering-damper ->more weight, less prone to wobble?
Personaly I'd hate to have that thing on my fork. Just put it on the frame....

Please enlight me
Matti

The triple mounted version with F@R holder, 2 Squadrons, fairing and all the brackets d the and fasteners weights in at 5.5lbs and the radius it swings is tight, the pendulum effect is all but unnoticeable for shorter rides, have no idea how it would feel after something like the B1K.

Let me know when you can ship.

Yep, had some 1/16" polycarbonate and had the kid cut one up out of a template I printed out, then he pop riveted it on. I'm not too sure how I feel about that yet, want to see how much dust will collect behind it. It won't be easy to clean.

Have to take care of all the guys that trusted me to get the project done first, should have that handled by the end of next week.

Preaching to the choir, there seems to be more idiots using it to prove an untenable point at times. I can't wait for a release that will weigh defined design parameters and learn, then make self modifications!

Thanks for all the links mate. DigiKey wasn't quite cutting it....

[640 Armageddon]

Paul that is indeed a great design, on the bike it looks even better !!
About the lab, The sewing machine is used to modify some fireproof suits for people that handle molten metal ... They do not come in sizes so we are trying to make their job easier. Make military straps for helmets, you name it... It was one of the nice additions to the plant There is a laser at the very end but eats only plexy and wood ... I may be able to make the Roadbook out of wood... Then you can use it to make fire in the event of an emergency


godwinmt

Nice design, keep in mind that you need to leave one degree of freedom (or two ). The lights have to be adjustable and so does the tower in order to have some angle adjustment. It is a preference I guess but it makes things easier if anything fails.

Off topic but we have to add to the knowledge pool here
There are indeed such programs Paul. You can choose which parameters the program can change (thickness, angle, number of ribs, thickness of ribs - for example ) and there is a technique called Design of Experiments. It was used for quality control in the old days but it can be applied whenever the combinations of the parameters is large enough. Basically the program chooses the combinations, runs the FEA and then comes up with the best design based on your parameters. These can be anything. Shape changes, holes, material, whatever... You know how parametric design works so given an Excel file you can do everything...
Of course such FEA come with a price tag (Inventor has such a feature but the Multiphysics from Autodesk is far better). So what you can do is find a Design of Experiments software, let it decide the values for the parameters and run induvidual runs from yourself. Back in my PhD days Toyota used to do that to decide the best shape for the torsion bars for some of its cars, Mitsubishi (MSSC) used to optimise shot peening parameters for car suspension springs. I mean, you can go crazy with these things but my approach is to run a couple of simulations to see if there is anything foundamentaly wrong and then make it. Then test it in the real field !

Sorry for the long pasage... got a bit carried out there....

[jesusgatos]

Recent SW releases have been making advancements in that area too. Their Simulation package is able to optimize designs based on user-defined parameters, but it's not a magic bullet.

Yup, that's exactly what I was talking about. That concept can be executed a number of different ways though.

Loving this fuse box, any leads on the brand/model?

Good call on the adjustability!...completely forgot about that drawing it up. The lights as it sits are adjustable with the 3 bolts/springs holding them on like most OEM's use. I'll work on it a bit tonight and break it up so there is some adjustment between the base w/lights and dash, or if i'm feeling ambitious break it up into another smaller section. More work on the front end and more bolted joints to fret (fret -> aluminum oxide ->loss of clamp load + fatigue cracks), but it should make a better product and help minimize the size of the raw material needed to get it going.
