Why do you want a gear that low on a bike? You probably won't be able to balance the bike using such a low gear.

My chain line angles will be like this even though boom is different. And it will have a mountain tamer chainring also. Frt chain wheel under seat and would like a front tensioner if possible.

[/URL]

Also experimenting with simplex style 3 speed mechanical front shift:

I use these chain wheels from Europe: Alligt chain wheels @

Just laced up the narrowest XL-SD in north america,,, well maybe,, (l bet ya). Now down the street in the morning to get trued for $13.95.

1) hub is 2.18".
2) brake lever width is 0.69".
3) axle bushing that welds to mono-blade is 1.62".
4) overall with frt fender 3.72".

[/URL]

Still gotta shorten the axle and weld bushing into mono-blade.

Two ways to use S.A. drum brake lever: imagine the strut is the mono-blade. Their both different. Which is your favorite?

l like this first pic below:

[/URL]

[/URL]

Thought about using 1 strut as a mono-blade/sleeve it full length for strength. Sleeve and mono-fork crown is one piece. The sleeve is needed because strut cylinder is not thick enough. Oh well, just a thought and thats all. Experimental thinking. I dont have enough info yet but l do have a strut to study.

Starting a 40mmx40mm latex air bladder 2 part mold this morning,,,,, with a tube from Netherlands. Tube has coats of duratec grey and is polished . Also using yellow fillet'ing wax from uk. Black epoxy tooling gel will go on in couple hours then carbon and soric honeycomb.

This is my second bladder mold, selling those on ebay now. 1"&1/2x1"&1/2,, 5&1/2 feet long. I need two sizes of tubes.

http://www.ebay.com/ulk/itm/322225847798

A cervelo sub contractor text me photos on how to make air valve and danny turned out aluminum cone valve, l made header that aluminum cone goes in from 1/2" phonelic and cotton flox with epoxy. Its a male & female type cone valve that penches the latex air bladder from peircan.com (a french company) in san deigo ca..

http://youtu.be/9part27ubaQ (a self youtube, l need to improve)

The 2 white boards are the disposal fence that make the 1st part of a two part mold. Two fences will come off after cure, then other side of 2 part mold will be finished. l have a store bought cf boom from Netherlands. But l need longer boom for my cf velo unibody so l made new bladder mold.

Took me 90 days to educate myself on how to do bladder molds on the first mold l made back when it was cold. Most rewarding.

Yellow fillet'ing wax from uk is great:

[/URL]

Finished at 5:30, took 1&1/2 hour for layup, tooling gel was drying from 3:00 til 4:00. CF twill (3oz & 12oz),, soric, biaxial cloth, cotton flox.

Some of this bike can go together with windshield adhesive (DOW CHEMICAL FROM EBAY) ,, got my eye on this electric gun on ebay.

http://www.ebay.com/ulk/itm/322180336523

Some parts of a store bought velomobiel are put together with windshield adhesive. Never use silicone.

I imagine that Warren meant, "What is the molded part for?" i.e. What part of the bike?

SHOP TIME:

the velotilt has hex foam sandwich'ed, myself and friend built the first Lancair 320 in nc ,, 93'&94'. Flew in 2 years he moved. l learned enough about 1/8" or 1/4" nomexhoneycomb & its strength.

I been layer'ing different kinds of cf. Some parts l make l think are to heavy or to expensive. There is waiste, l make design mistakes. I may order some nomex honeycomb soon. Plus the workloads are way less and much less layers and lil' cheaper. I had learned some tricks of installing nomex some years ago at sun-n-fun from david algie group. With chamfered perimeters it can lay in compound curves easy that adds great strength. I attended sun-n-fun from 92' til 2012. The best builders on earth were there one or multiple years. Was very fortunate to be involved in 90's.

I usually make multiple phone calls to double check my thoughts. Dang retired life is great.

oh no, tired after this dang layup,, but moving forward every day! Have all parts now and will slowly assemble. I have a customer for a velo shell and that comes first, so l just mix the two projects together. Worst of 2 wheeler is over and next one if there is, will be lighter. This is a neighborhood modified tetz cruzer. Hope its like'able and turns out good. My trike is done and riding it now 10 months. Soon two wheels will be done and lower velo shell for customer will be done but l will not slow. Just a good pace. Wish l could sell my big truck.
