How l started. My airplane molds (BD-5) l own are used for cf velomobile unibody. Ideas/conversations are welcome: march-7-2015 [This past MAY has been 2 years].

My molds favor this shape:

Rear cowling will look like this photo below, my velo at rear is 5" wider: plus i have a rear bulkhead like the WAW velomobile.

Still doing boring body work.

Prepped mold for few days, speed buffing. Then mask, then wax, then spray pva over wax. 2 layers of carbon with polyester resin, pop it out tonight. Put my formica table top back on mold for my roller table. Double duty. This lil' black part will be for plug. The top of velomobiel plug/mold.

2 carbon parts: this one and post above makes base for plug. 2 more carbon parts sit on these two. These 4 pieces make plug for mold.

Plug under construction for top that will be removable. Bolted down with eight 4mm bolts into rivnuts inserted into frame base of the upper top. Upper top also has big inspection door above pedals.

This is mold that made the light carbon base frame:

This photo below is fitting the upper base frame to the top rim of unibody. Bout 9 hours. U see rivnut, the kit is $34 on ebay. “Instant nut squeezed into the carbon bodies where you need them with squeeze tool that comes in kit.

Nine rivnuts hold top on. Easy off. Rides on twelve rubber dics installed w/pliobond.

Tv show filmed hour & 1/2 today inside. Rained! Be back next week for second part with couple go-pros on velomobiel when sun comes out. Show up again tomorrow morning.

Working on belly, i want it smooth:


carolina Posted - 12/09/2018 : 09:05:14
Still sanding, close to rolling over the unibody and finishing belly and the two wheel wells. Amateur is ok, keep learning. Entrepreneur , no! Medicare and ss is more fun, hehehehe. This one will be painted white with adds on side.

The auto body warehouse supply has always helped me with new products, they learn from body shop owners and l learn from them as it’s passed down. “PRO TIPS” from people doing it for many years. Same with composites industry. My friend is production mgr at pursuit boats. He has gave me contacts and told me many modern techniques in boating industry. The contacts on phone especially.


Over the hill on the kervelo, starting on rear rack that holds gear and top seat mount. Try to find left and righ panier bags.

Well, send me email, big time velo excitement here always.

Man, thats looking good. I'm gonna have to take a road trip one day to come down and see your work. I'm in Greenville, NC.
carolina Posted - 12/04/2018 : 12:47:45
This is base rim mold of top:

I have top fitted, now to join it to base rim with fiberglass and gallon of bondo. Then more sanding to make plug upper.


carolina Posted - 11/29/2018 : 11:15:58
Warren: tv show bumped up 10 days, cameraman he uses went to emergency hospital for something.

The new upper setting there, stare at it and measure. Later it will be foam, wood, lots of bondo. A bunch of work i will do to get a good shape and pedal clearance.

Last years top : take the yellow one for a spin soon.

Mock-up of side mount front derailleur. Try to figure it out.


carolina Posted - 11/18/2018 : 09:02:27
Just slow body prep and light primer going on, nothing to show. Experimenting with my air brush for spraying thinned primer for unibody and down in the big lower mold/tool that then gets wet sanded smooth as possible in mold.

Installing rear WW’s.

Yellow Quest ,,, and DF four wheeler prototype photo below:


carolina Posted - 11/10/2018 : 16:47:30
Working on fit at rear. Four wheeler WW’s going in and body work. Wheel base 46 inches.

Last night and lil today: measured, drilled, & cleico’ed rear 4 wheeler unit in.


carolina Posted - 11/08/2018 : 11:48:47
Well, here i go trying to put these pieces together. Top pieces will be a plug to make a mold. Rear WW unit setting there to be fitted. Its a unibody so there is body work much.

Top is down forward, (top plug is 4 pieces with some bondo, foam, wood, & much sanding) can’t see in most pics. And i have pedal clearance. Will be riding it topless and no rear cowling for a while.

Thank heavens for mavcoat release. World record holder solo, yep l gotRout by myself. I owe it to Mavcoat release. If ya like watching wrestling, ha,,, thats like what it is. I did learn some stuff/tricks for next time to ease release.

Well you’ve seen the rear ww’s up above, they will go in the rear of this blk carbon unibody.. When i get better there will be less waisted time doing light body work on outside of these unibodies.


carolina Posted - 11/05/2018 : 20:52:22
This is 4 wheeler: pop out of tool this week later, try to make a vid.


carolina Posted - 11/01/2018 : 23:15:37
1st layer of rolling chain canal. Have a seat with peel-ply.

Yellow Dacron peel-ply is so wonderful. Throw in the garbage next day & keep rolhoff’ing.

Only rear bulkhead to complete:

More pics of unibody. Floor and rear vertical bulkhead left. Then let cure.

Did left & right rear walls today.

All the hardware from this will go in carbon unibody, then heavy frame an fenders in storage.


carolina Posted - 10/30/2018 : 15:27:19
Just for this nose area in front of wheel wells. The rest is more forgiving going reward.

5 hours, tough work! Twill (2), uni, innegra. Did learn couple techniques that will save me on next one. Thats just the way it goes.

FLOOR/chain canal last.

Amateur carbon layup/2nd velomobiel:

Nice one piece front wheel well layup, some hardpoint locations are 4 layers (seat mount & vertical layers for Macpherson strut). Takes at lesst 3 hours to cut patterns, carbon and layup. By myself l use peel-ply to stop and start another day. Do other ww soon. WW’s are worst part. Quattrovelo uses 5 women to do the unibodies layup, i need 5 women.


carolina Posted - 10/25/2018 : 08:38:07
Been working on experimental plane i have for sale. After this 4 wheeler is completed l want to build another small plug and mold/tool. My rear cowling is removable and i want the front removable so if wrecked in front or rear hopefully the whole velomobiel is not damaged. Just replace front or rear. Like the waw, it makes for ease of transport. Well, it’s something to thing about.

1)No soric, no density foam in velos.
2)cutting some patterns today.

I use 4 kinds of carbon:
1)11oz., twill
2) uni, looks like a wooden deck all in one direction.
3) 7oz. Twill
4) thick biaial carbon
5) innegra in between carbon layers.
