My molds favor this shape:

Good progress Mike. This will be for a trike, right? Wheels on the inside of the fairing?

warren, This will not be shell for a trike, this is full velomobile. My velomobile is a frameless unibody.

Square cf tubes l make will be used on 2 wheel low racer .

l make my own carbon square tubes (rewarding project l took on to learn) and carbon plates sold on ebay under toys and hobbiest section. Two part bladder mold for the square cf tubes:

Very interesting... did you use factory made suspended linkage assembly or fabricated it yourself ? If latter, what kind of bearings if I may ask ?

Cheers,

Great job on building the parts! I really like the way you are molding them. That is one advantage of using female molds.
So I see in your pictures that you have a set of ICE front suspension hubs that you were/are planning on using, but when you show the front wheel wells it looks like you are setting them up to use McPherson Strut style front suspension. So are you just leaving your options open at this time?
Keep posting pictures it is great to watch your progress.

Making my own carbon plates: Soric honeycomb and carbon fiber twill 12K.

Lay-up is between two granite plates (3/16 or 1/8") : I make 6"x8" plates, They are great & straight.

Hey Mike, I recommend polycarbonate or even PETG over acrylic. Acrylic tends to break into sharp shards when broken.

Bought a rear cowling (wind fairing) from europe. l will make a plug with it and then pull a tool from it. It will speed up the rear. Pressure recovery unit, lets call it! So easy to change rear tire.

I did build a velo trike with all velomobile parts, love it, ride it often (8 months). Blew the catrike 700 to lil' pieces. Sold the catrike. This is my basic shop learner vehicle. In Europe these are called "mules". A mule was used to design the 4 wheel velo in the Netherlands. So l built myself a three wheel mule.

if you have a shell you have a shell!! All the velomobile hardwares come to your from door as they come to my front door. I make all orders to Europe on my iphone for 2 years. Very simple, excellent service. velomobiel.nl, intercity bikes, katanga.eu

All modern parts come from Europe nowdays for a velo. (rohloff, pinion, alligt parts, etc..)

The rear wheel well mold will be cure tomorrow and i will take it out and clean up all the tape and stuff. Trim the mold outside and polish edges. Wash it and seal with frekote. Has a great chain canal that adds super strength to velomobile with innegra,twill, & biaxial carbon cloth layup. Honeycomb (soric) & innegra used certain places during layup. FRONT WHEEL WELLS ARE IN THE LOWER SHELL MOLD PERMANENTLY TO MAKE A STRONGER UNIBODY.

Yes, another rear wheel well project: for single swingarm rear wheel well. One more step in this project.

I made this to make a plug,, that i will duratec and polish to hi-gloss. Then pull a two piece mold from that. I will have 2 rear wheel well molds that fit perfect with windshield adhesive.

Techniques for fast layup and straight cuts. I learned this in 93 when we built the Lancair 320. I use some vinyl floor tile, visqeen plastic. I sandwich'ed the carbon between visqeen that is wet. Then roller cut perfectly square and pick up with gloves and lay in place gentle. You can stipple with finger and brush. Sometimes l put on peel ply with finger holding it in place till wet.

This method makes a perfect square patch or bid over joggle that looks professional.

Warren, the upper mold l have is one piece.

The lower is L. & R. halves (bolt together) and i worked for-ever on the rotisserie. Thought it would never end/:) But you know some projects in the shop go smooth and quick, some have ghost!

Oh, you are wondering about the layup schedule. Is it going to be monocoque or using a frame?
