The squadrons are fairly heavy. Mounted direct to the forks there would be some pendulum effect

Nope, you have that wrong, Squadrons weigh in at 12oz ea and the Rigid's are 20oz. The new SII's are half a Squadron and weigh in at 8oz, the spots are incredibly bright, as soon as they come out with a wide cornering lens for them having one spot and one WC will be about perfect for only 16oz. I run 2 Squadrons in that config and it's great for 24oz, just over one Rigid.

As far as pendulum effect, I hardly notice they're there.

From what I have seen the PE pipes that I have used before they get soft if you leave them in the sun and then they retain that shape when it gets cold. I am wondering if this will get softer after racing in the sun. Thoughts ?
Yet to be proven.

8mm is pretty stiff, there is some deflection but it springs back, not sure whether it will vibrate like cheap mirrors and make things unreadable. I will need to load up the roadbook with some weight to see what the wobble is like. Will report back when I give it a shake down test.

All I have read is that the heat deflection temp is 85C@0.46 MPa (66 psi) and 60C@1.8 MPa (264 psi) with a melting temp of 130C. So I guess under pressure and in the sun (particularly black) it is not inconceivable that it would reach temps of up to 60-85 degrees and warp. Perhaps airflow keeps the temps down. I dont plan on racing in the Fiambala! Then again, Paco Martinez raced dakar last year with HDPE tower parts and survived? Time will tell?

Not sure how these compare with visionx or squadrons but damn the price of those 61s by comparison is good. Latest offerings from Sanjoh (advmonster):

Jeremy, materials alone cost about half a new 500XCW, then you need a big enough CNC and software to run it, all the overhead, blah, blah, blah. Free, is kind of stiff, it's like saying "You didn't build that". It's a risk I hope pays off.

Gany, we went out all of yesterday and a few hours last night, mine are only 1/4", just over 6mm and there isn't much as far as vibration and it has no lower attachment point for the tower, all cantilevered off the submt plate, the whole thing.

For example Laia's tower in this dakar broke and had to carry it in her back swapping it between her teamate because it was too heavy ... Of course the load has What I am interested in at the moment as far as the Towers is concerned is how to make them collapse if they get hit by the rider, much like AntiPaul did with his first design. That was a very nice feature. As far as the other equipment is concerned you have to make them completely bulletproof. I would prefer to add 200 grams on my roadbook and make sure that is stronger that making it a featherlight unit that gets destroyed with a light touch. You know what I mean...

The subject tha Paul started with an FEA program that will give you hints about the shape, I remeber Designspace from ANSYS which would automatically remove material from the structure. Material that did not do anything as far as the loads and the supports is concerned. You would choose the percentage reduction and it would try and achieve that. Anyways... Back into the Towers ...
Dimitri, I started looking into the packages that are out there now, wow, makes me feel like I'm in the dark ages with what I have, CosmosExpress/SimulationExpress, if I only had the money for a seat of Catia and Simulia/Abacus!

I have the sqadronds. My opinion is that theyre heavy. Sorry for my opinion.

They're lighter than my lapaz dual hid frame mounts but for a compact no reflector light they're heavy,

Those might be worthwhile looking into, couldn't find the weight and the wattage does not add up to the Cree specs for lumen output. Also look pretty much like a BD knockoff, and didn't see anything about a warranty?

This is an on going issue with designing in your shed. Options keep changing!!!!!!!! The mount on these lights is a bit easier to mount to that the other options. Maybe a higher output version in the future?

No problem, you're entitled to your opinion, but at 3/4lb and true 3600lumens what are you comparing them to?

I have the HDB nav tower "lite" on my 690 with one squadron and I don't feel it at all.

Then if there are heavy for you I will help you lighten up your bike. ( Give them to me )

Your thinking about it all wrong , it not a negative they are heavy it's a positive , it's front end traction and it helps with the weight distribution for a evenly balanced bike

I was planning on leaving the key barrel where it is...I wish I had my WR here (360 miles away at my parents until my doc gives me the OK to ride again which will be a couple months yet ) and I could get that part of it mocked up. Looking at a few others i've seen, it shouldn't be too difficult to get the mount low enough to get teh tower scooted forward enough to stay out of its way.

Anyhoo, after some suggestions, here's rev 2. Big difference is splitting the tower into 2 sections and adding slots for adjustability so the roadbook etc. can be shifted forward and tilted as needed. Current weight is 5.4lbs, but most of that is in the bent plate up top which I have yet to lighten. It's getting there





As for the mask, I'll be using one of these setup for a WR:
