I have got to build a lowracer. My favorite is john tetz . Dad is 90 and gets around great but l gotta get him riding. He plays golf 2 or three days a week.

I will make of carbon fiber. I make and sell square cf tubes on ebay. I will have a new style boom, @ rear will be 26" & 20" up front.

l like john's more uprite and shorter angles:

[/URL]

Will look like this from seat backwards but with no frame. It will be hardtail unibody with no frame. l will use cf 12K twill, innegra, nomex honeycomb. l will use my velomobile mold to make rear, this unibody 2 wheeler will weigh less being all carbon. Enclosed chain canal under seat all the way back to rear derailleur. Enclosed wheels front and rear. Sturmey Archer drum hubs front & rear.

[/URL]

Will have chain canal, runs whole length out to rear bulkhead. Help keep stuff clean.

Carbon fiber square tubes up front will be glued with hysol aircraft adhesive: Also will need uv clear cote over carbon. Or a color. l have seat mold and iam making a new seat (plug) with lil' more height for neck & head.

[/URL]

Maybe a pinion: below 18 speed, maybe to heavy up there.

Yea, saw that. I like what l bought to see if it welcome here:) with my 18 sp pinion. No electricity on this one, guess thrumb throttle w/rear hub motor would nice.

Kervelo are just running their first batch of their own 12sp gearbox, either as a direct drive front hub or as a "regular" gearbox. At Spezi they claimed it would be half the weight and half the price of the respective 12sp Pinion C- series counterpart. And electrified, if you are so inclined.

Coverting this (lowracer above post) to chainless would be fun. Using the kervelo front with 18 speed pinion gearbox. You could change it back to either bike, just need extra piece of that aluminum tube for head tube.



Just head tube circled in red.



You veterans remember this old lowracer: copy it using the new kervelo front hub, mike states it痴 hard to ride..


Lowracer amateurs like me, this might be a way out.

Finally after months of casual work on 20 full fender well mold i am prepping. Will use these molds to complete my rear components that make my unibody a 4 wheeler (rear wheel wells).

Black epoxy tooling gelcoat and carbon and soric over tooling gel. I always keep learning tips and tricks for plugs and molds.

Before frekote l buffed split mold with wizard compounds and my flex german made hand buffer. Dont be home without it.

LETS NOT FORGET DURATEC PRODUCTS/YOUTUBE , compositeenvisions.com, and rev-chem in Southern California.

U see the yellow can of frekote product.
1) frekote cleaner gallon size
2) frekote sealer 4 coats
3) frekote release 4 coats
4) 7 coats of the great TR mold release wax (ebay) over frekote.



Brevity and misspelling rampant (new eye lens couple weeks ago)

Photobucket is down:

Worked much more on the fence for two part mold of the front fender plug. Takes me so long, about 8 hours to finish & fix that fence. Now i will wax the plug 7 times with TR, reset fence and make the first side of the mold which is easy.

I learned alot from this video and buy from these UK people.

Did switch to lauan wood ($7.48 Home Depot) on larger velomobile rear cowling plug to make the plug 吐ence instead of using polycarbonate.The youtube above technique and the lauan wood made it easy. Nice to have these two plugs ready to make the split molds/tools from them.

They bash your neck if you fall that way.

I race fatbikes in winter. Very fun.
Speedbiker Posted - 09/15/2017 : 05:01:08
That's weird. Anyway, I hope you didn't build that over the shoulder frame tube. They are quite dangerous in a crash.
