1)Since i will ride with top on or off till completed I used the DF velo rear seat hardware to change out back and forth while body work on top plug goes forward. Cotton flox will cure til 6:30 then layers of carbon over these two pieces of wood that is the base mount.
2)this allowed me to remove the temporary crossmember behind seat l been using since beginning. Plus try out this new idea of seat resting on headrest from daniel Fenn. If i make a new top modified seat, l can cut this experiment off of the plug.

1)above photo is tab on both sides of milan gt seat.

2)Below pic: the seat rest in these floor mounted bracket saddles, L&R on floor,, u can see how easy it is to take seat in and out.



3)Below photo is another great idea: seat top leans on headrest getting rid of any other upper hardware.

PINION GEARBOX:base mount in carbon.
worked last night up til now on this pinion 18 speed mount mold. Black custom fitted pinion plug u see got me here. The center part between two orange pieces l poured down in between two orange parts (cotton flox and poly resin) for the 3rd part of this mold. lt is tight & fits incredible. Never tried that before.

l have L & R trim fixtures after part comes out. All six holes of finished part are pre-drilled before relief from mold. Then trimmed and 6 aluminum rivnuts installed.

PHOTOBUCKET is down right now but pics can come later.

I have finished pinion and rohloff middrives finally as a display. Either gearboxes go behind seat on floor low down in the wide chain valley for next year.

I am still using the hilgo floor shifter and 9 sp cassette in the 4 wheeler with F. Schlumpf mountain drive 2 sp crank up front.

Nothing going on but slow bondo sanding every day. These are all plugs below to pull molds from:

Grey is the plug/master that the mold will be made from , ready for wet sanding soon:

The lower of this rear cowling is already a mold, the grey area will be 1 of 3 piece mold.

jan 5/ wet sanded, sprayed 3 more coats, now last wet sand and polish.



Also as said before: fiber glassed over toe clearance humps with 40 ounce fglass/2 layers. Honed out inside and put it on velomobiel for test ride/all good. Now iam adding bondo over fglass to sand and ready the two humps & whole part for grey epoxy primer.

Just different options. You値l haf to read all the post.

No delrin and not near any heat. They say not to use rear brakes that much just the other day. I installed sturmey archer, i love em and on all 4 wheels.

1) you saw the stock pics of quattrovelo with mid-drive ROHLOFF up above.
2) hilgo floor shifter is for 3 wheeler, but i had a trial with it. Pretty good!
3) the Pinion middrive with short gates belt is my project. A take-off on rohloff痴 middrive.
4) read about the quattrovelo with straight axle, can jump cogs over humps.
5) last year was 3 wheeler with bafang up front and rohloff at rear in waw linear supension.
6) oh, dont forget the schlumpf mountain drive up front now.
7) everyone wants something different.

OK i am losing track of all the gearing options going on here. A Pinion in front, a Hilgo middrive, a rohloff and then the cassette on the rear axle?

Next to the drumbrake i think i see a delrin spacer. Would that cope with a hot drum?

Greetings, Jeroen

Amature build here:
1) a useable plug to test ride.
2) covered over all the foam/bondo work with fglass.
3) pedal clearance now close to wet sanding.
4) also rear cowling plug is getting ready to be sprayed with primer.



I sanded out inside of clearance humps with 3 different tools:
1) now l can ride and see if alls well on clearance.
