I stated PETG, since that is what I made the windscreens for Hans from. Here's a picture of the plug I CNC'd

Not to be completely outdone by the awesome work of our fellow competitors, The CNC process has begun on our shell. Raymond Gage has been racing against the clock to complete the design and slice it into 2" sections which can be cut on a 8 x 4 x 5" Z machine under the direction of Dr. Dave at CCSU.

What is particularly nice about this method is that the parting line for the top and bottom half is already built to a slice and the interior will almost all be easily popped out due to perforations that are holding everything together during the shipping and the outer layup.

Relatively light trim work of the foam will be necessary to get the interior ready for an internal layer of composite.

Here is a screen image and a 3d print of the design.

Garrie, how did you form it over a male plug?

I think Garrie gave a duplicate chainring to Steve this year in Florida....



Back in the 80's TA made custom rings to fit their Cyclotouriste chainsets. They were, however, somewhat spendy - about a pound a tooth. IIRC Poppy Flyer had a 140...

Larry - 140 teeth x $7.203 (pounds to dollars corrected for inflation to 2012 ) = $1008.00 in todays dollars!!!! Last I checked, Dennis Grelk would make anything you need for $1.25/tooth.

Thom - I don't use the male punch. It creates the female mold that I use. Since the inside surface of the female represents the outside surface of the fairing, the windshield mounts flush.

Battle Mountain will indeed be crowded this year.




I suppose if Vin Diesel built an entry, it would be "VeloXXX"

I wonder what the cutoff limit will be to get into the evening sessions...actually, i wonder what it will be to get into the morning sessions too! There will be a lot of bikes this year...

Bluenose is put on hold for now, while most of the team is going forwards with the helicopter. We are planning to have a new fork, redesigned steering, wheel fairings, etc. Need to find the time.

non-virtual fairing parts from Dr.Dave at CCSU!
Looks like I won't need to do any sanding on the exterior.

Thickness surfacing will be done last. Note the slight lip at the top edge.

I've spent the long weekend down here prototyping my 'BG65' low Q sub-frame in steel :-)

http://www.facebook.com/media/set/?set=a.325132590894736.75537.230832480324748&type=1

Warren; not sure how your progressing with your sub-frame but I have my mid drive in the nose so taking a look may be of interest.

Garrie;
just wondering what you machined that windscreen plug out of?

Ben;
https://freemansupply.com/RenShape5440Stylin.htm Polyurethane foam board used to make patterns in the casting industry. Very much like mahogany in physical properties, while unaffected by changes in humidity and temperature.

Victor,

I aim for 65mph in qualifying to get a definite spot during the evening sessions....

Are you guys crazy, it will take at least 70 mph (112.65 kph) to get into the evening sessions this year! Its going to be a fast year - unless the all-mighty one sends us snow, ice and wind or something else to contend with.

The availability of evening slots will be highly dependent on whether folks try to run the same vehicle with different riders in the two evening sessions.

How many folks with multiple riders for the same vehicle will be trying to do this?

Should my vehicle prove to be fast, I will not be doing that. I'll be running once in the morning and once in the evening.

Maybe ten over seventy in the final. Seems like at least that many have the potential.

psst, VeloxX is not the best choice for bike names.
HPT Delft's first bike was VeloX and their new bike is VeloX2. I know the name was chosen out of respect for the HPT Deflt designs, but there will surely be some confusion when folks write/type entries, results, or talk on the radios. (Let's see if people figure out which X to capitalize.)

It's a good thing Velox Solium will not be racing.

Vector --> Varna --> Vortex --> VeloX - if you want a fast bike, just name it with the letter V.

We could possibly pull down Velox Solium just because. . . It's the original Velox!

Makes you want to own one of those CNC contraptions.

It won't be long now.

the organizers are going to have to make some hard choices if everyone shows up

Last year, the maximum number of speed runs was 14 in the Saturday AM session, and 9 for the evening sessions on Tuesday and Wednesday. The number of speed runs in the morning is reduced if you have qualifying, and last year, we ran 15 qualifying runs in the Mon AM session, with no speed runs. If all 42 of the above run, this will take basically all of the AM sessions Mon-Wed just to get everyone qualified, which means that we have a theoretical maximum of 73 speed runs for the week. If we guarantee at least one speed run per participant, then we are down to 31 other runs......

Maybe moving some of the qualifying back to Muleshoe, and having qualifying all day on monday (except for the evening speed runs on 305?)

just to provide some additional context from last year, in this picture:
http://jnyyz.files.wordpress.com/2011/09/allriders.jpg

I count 20 riders plus two for the Henrys, who had already left by Saturday night.
