Newest kit amp at parts express dotcom. I use exciters (speakers w/no cone) from mouser. German companies with office in Dallas texas. The amp weight is nothing. It is bluetooth.



I use 4 of these Mouser exciters installed on carbon with dow u-428 (ebay). They use the carbon body to make sound. I have had this in yellow velomobiel. My Boise radio is not used anymore for music, just listen to velomobiel.

BAFANG 1000 W-HD BATTERY:

My long friend ray and i are making our own batteries nowadays. He want wire one without BMS (battery management system).



I wanted a special one, flat like a huge history book in jr. high. 52v carries in backpack with the new magnetic plug (yea) from ebikeschool channel on youtube. Move battery from 2 wheeler to four wheeler. If ya fall off two wheeler the magnetic plug releases with no damage.



The battery management system board came in and I finished carbon box with 6 rivnuts and screws.

I pulled carbon top yesterday from a 4$ plastic tray from Walmart. With mavcoat release agent on tray (5 coats every 15 minutes).

I bought a rivnut kit (needed lil care) from ebay, now its great,, i then bought a extra box of many sizes of mm rivnuts/ebay. Then i had a discount at harbor freight on the big yellow/black storage box in photo below. I have rivnuts color-coded and matching drills and reamers for each hole. Velomobiel rivnuts are aluminum. I put lil lanolin on threads of aluminum rivnuts.

After few months, designing base plate, measuring zillon times, getting new 10 speed chain,,, i just installed the hilgo velomobiel floor shifter (used DOW u-428/ebay as I always do).

As an experiment to work with the quattrovelo rear-end 10 speed sram. Hope it works, some might want to use it.



Heres short vid of how it works:

Difficult experiment but lovin it. Last night late, made a great change. The 1 tiny 11 tooth hilgo chain wheel changed out for short piece of quest chain tube. So smooth now, will help in shifting if ever a way is found. It is a rolhoff twin cable twist grip. No indexing.

This one floor shifter change wasn’t great because this floor shifter is for a 3 wheeler.


Ordered some custom chain wheel bearings for 10mm chain wheel axles. Changing to this wider softer chain wheel i make on my lil mill. Chain moves left and right from under seat. Stock chain wheel to narrow. This should fix that noise. Huge chain wheel axles/10mm,,, front and rear chain wheels.



Been riding lil every day, does pretty good but it’s not a rohloff or pinion.

Below pics:
Pic1-Shoved 2 inch foam in last night in big hole and covered, this morning, sanded sharp stuff.

Pic2-Now you see block foam inside this morning ready for shaping.

Pic3-Now u see sanded to shape to match other side with white micro.

Working night shifts, all holidays, and all weekends.





Above pic ,, building a lil 2” mold to sit in mold to get left and right angle upslope matching at rear of valley. Its for the 2” rear joggle that accepts the rear cowling of the velomobiel.

13 bondo tiles i put in today, more work at front of chain valley.



I don’t care how long it takes, try to get it perfect: i cut more out today, already filled in.



Symmetrical chain valley at the back at base of bulkhead.

Made another lil mold. 14 days probably 1/2 hour per day. Carbon pinion gearbox mount. 2 part split mold.

I had thought about the 4 wheeler. Pinion mounted behind seat on floor with gates belt going back to the quattrovelo rear-end. Chain going forward under seat to crank.

OSCILLATING TOOL HEADS WITH MANY SHAPES : soft head, pointed, wide, hard to reach 90 degree areas.

Over the weekend i came up with a newer model of these oscillating tool heads. [“””””Plastic velcro with glue backing takin’ off w/acetone”””].

Then installed on tool head with dow u-428. Dow can take the heat. The expensive sanding paper is expanded see thru type. Tried regular velco, no workee! Plastic velcro takes the heat. I’ve tried different stuff for over a year.

Will report back:

********8/20/2019 update/update: these are bullet proof and holding up great sanding hard stuff (tooling gel coat & epoxy w/cotton flox) with oscillating heat. I have different shaped heads for tight places.

********8/23 update. The yellow pad can bolt to harbor freight metal tool head or go on with the dow u-428. Will not come off either way.

*********8/24 contact cement helped out alot, but still searching for more perfection in the tool heads.

*********
*********
UPDATE:21/October/2019. I now use sticky back sand paper. Take heat 10 times longer than velocro backed .

I was glueing blk plastic velcro on with the dow u-428 with half success. Now I switched to sticky back hi-performance sandpaper,, it’s performance is Best. Not many posting stuff like this, not many if any sanding epoxy w/micro balloons. But the harbor freight tool I would not be without.
*************


————————————-
This is the hi-line sand paper i use from auto-body shop supply warehouse. 80 grit MIRKA. It’s great stuff. Goes on the velcro. Sanding epoxy/micro or bondo down in these compound curves is tuff on anything and oscillating cause high heat.

Sanding in shop: I built this box with vaccum hose in it. It works great. I can use oscillating tool and keep skim coats of bondo going forward till ready for primer. I can flip box to rear of wheel wells and keep sanding, then move it to rear of the chain valley. I brush dust towards vaccum with paint brush. Shop has A/C, its 90 outside.


When ya brush on some primer ya see ya mistakes:) Spray final coats after wet sanding. This grey is lighter in color. Fills scratches. Its evercoat featherfill.

This mold can make a waw type rear (hard tail or soft-tail),,or regular 3 wheeler swing arm velomobiel,, or the 4wheeler. Back at the hard tail area i wanted more flange. Got on that this morning.

New stuff from netherlands. Mid-drive gearbox/transmission behind seat on floor. ROHLOFF 14 speed:

This is so simple, zoom in u see the flange kit they sell that bolts on to the holes where the spokes go with 32 lil’ allen bolts. The cogs are 17/28. The 28 tooth cog goes back to the rear cog you choose on rear axle. The 17 tooth goes forward with other chain to your 2 speed chainring set up or bafang motor if you want that. The short chain want jump off of rear axle cog on this 4 wheeler. I really wanta find the correct length Gates Belt and use it from rohloff to rear axle cog on the four wheeler (quiet, smooth, last forever, never jump off). There are many cogs for Gates Belts on ebay and at gates corporation.

Welded up a seat base for right side of velomobiel lift today and painted it ( l have a small mig welder). Used a piece of hardwood for seat base & 4 six mm bolts. One more piece of foam to cut and hunt some naugahyde down the street to staple on to the wood. It’s a 2 foot seat.

Lift has wheels and stands up vertical on wall out of the way if needed. The seat stem has a pull-pin too. A NEEDED SEAT.



The 4 wheeler is lil tail heavy. I roll it backwards at an angle to the lift then pull it up & forward with the nose of the velomobiel over the markers even with the twin fglass belly saddles l made. Then you jack the lift up with foot pedal, the saddles grab the belly of the velomobiel. Put legs down and level with second hydraulic pedal.

When adjusting the 6 tie-rods & 12 rod-end bearings l can lay under velomobiel on packing blanket and pillow. Iam beginning to learn more about toe-in, or 0, or lil’ toe-out.

I put plug in mold and shoot foam in it for structure.

This orange mold made yellow velo rear cowling. Its a 3 piece mold. Now all l do is change top piece after i make it. A new df style 3rd bolt on piece. So, this mold makes 2 different rear cowlings by changing one part. Original top piece that made yellow velomobiel is in bedroom. I will make a new orange 3rd part.

1)Rear cowling is one (1 piece) now. Tomorrow fglass inside to hold it together. Then carry on with sanding.

——————————

2)Layers of foam on the front now to sand to shape for toe pedal bumps & clearance like milan velomobiel when pedaling.



3)Bondo sand Bondo sand Bondo sand. Think of playboy magazine for shapes.

Contact cement can be used alot in shop. I don’t need the dripping brush, just pour cement in smaller container like this. Thin contact cement with MEK 10 to 20 %. Or how thick or thin u want.

MID-DRIVE TRANSMISSION YOU CAN BUILD EASY:

The post at very top of this page and this post tells story of rohloff mid-drive in 4-wheeler.

The kit came today from netherlands (velomobiel.nl) with some extra spokes to tune up my 2 rear quattrovelo wheels @ lbs.

Bolts onto rohloff. Cog going rearward and one going forward. 28/17 tooth cogs. Extra spokes i pic I ordered for spares.



I have it mocked up now with disc off that I will not need. Beautiful coffee table furniture.

Nothing going on but bodywork with bondo.

Really alot of monotonous body work on upper/top and rear cowling. Ordered a 10” profile gage to go to my 6” gage, they have magnets on ends and i will join for long runs to match left and right knee & toe humps on top.

Made a jig table outside: update ,, 90 in October,, mosquitoes in hot weather,,, I moved back inside on a roller table. I can roll outside garage door / shut door and sand rear cowling and use air hose to blow of dust then roll back inside. Much better.

Also bought the 10 inch profile gage (ebay) which i should of had for couple years to go along with the 6 inch profile gage.

Use imagination: i love these 4 wheelers.

Mask all over and covered. Roll outside and sand seam/joint line between rear cowling and head rest (scribbled yellow line in photo below). This should give me close lines on the plug to start primer and kombi putty and hours of wet sanding on this plug.



I will make a second cowling after this one is complete that is bob-tail with the insert for lights,reflectors, and plate like photo below. It can be kevlar part with first thin fglass going down then kevlar. Be nice to know a vaccum former friend. Plug and mold (tool) would be simple.



This is what it looks like with rear cowling off.

Pics few post down:

Another great gearbox from Germany came today used on ebay. Schlumpf mountain drive. Already mounted to my velomobiel aluminum BB. It has chainring/chain guard. I will get danny to shorten crank arms to 145mm later. Not, l like the 170’s. This is incredible gearing, u change gears with your heel, just tape the chrome button on either side of crank arms.
———-
Located another second ROHLOFF (bidness & l won) in Europe today and paid for it to my door laced to 26” and with Rohloff cable box at rear and twist grip. ttd$494. Should not need another ROHLOFF any time soon (my second in 10 days bidding). I have the carbon mold for the pinion mount also i need to work on.

This is a plague started by jerry when i bought my first pinion from him over a year ago:)

Mock-up, its perfect! Chainring sits out on pinion and schlumpf drive becsuse of my wide-wheel chain tensioners i make from roller blade wheels.

I turn velomobiel aluminum bracket backwards: its perfect for space like pinion 18 speed.


Put it in, i like it a lil’. Rode it around few miles. Ordered a spider for it to bolt on a larger chainring see’in iam an animal. I love my homebuilt beefy chain tensioners. 5/16th chain wheel axles.



Utah trikes had one (above photo). I like them, I hate siri. The 170 cranks are taking me faster. Remember there use to be a Pinion 18 sp sitting here.



——————————
With this Florian Schlumpf drive i can futher my work on hilgo velomobiel rear floor shifter to work at rear with quattrovelo rear-end and get it to index.
