Hey Rick, are you planning to use a simple U joint like many of the commercial velomobiles do to solve your steering joint issue you mentioned briefly before?

Interesting that you would ask that question because today I was looking at the u-joints in my tool box. I have not looked at McMaster yet to see if they have any off the shelf ones that will work before I start to make one out of chunks of aluminum. I will also be cutting down the width of the handlebar. This picture is of the extra handle bar width when the wheels are turned full lock.

Not to worry Rick, I have a spare prototype you can have for free if you're going to Indy. I can bring the pieces down for you if you like. It's designed to fit inside the standard OD/ID handlebar tubing, something like 7/8" OD with ~.063" wall. Not sure on those dimensions though as I haven't measured it in a while.

Do you think it changed over time Tim?

And yes, that can happen; I've seen sheetmetal "grow" to double thickness due to corrosion...

That would be great, I have several (hundred) other things that need to be done on the vehicle, so I will skip that one for a while. I would like to get the frame and tub working together before Indy,

PS, the size does not matter

Please bring your calipers to make sure it's still the same size when you get there...

The velomobile is on it's own wheels for the first time. I brazed the mounting tabs on the frame and re assembled the lower tub to the frame. I also decided to make the seat tiltable so I can get to the battery and other things in the bottom. Here is the seat tilted forward, you can also see the rear mount.


Here is the lower tub and the frame on the ground for the first time.


Here it is with the top added, It is really looking good.


I sat in the vehicle and marked out where the foot holes need to be. I will cut them out next next and start putting the inner layer of fiberglass on the body.

I cut out the hole in the top section of the body.


Here I am going 120 MPH (In my mind)

So I have been able to sit in the vehicle and check clearance and other things. After looking at a side view picture, I decided to change the back turtle deck so it was closer to the back of my helmet and also make it easer to mount my version of the Felvo roof.

Here is a side view with me in the velomobile.


So I mocked up several back sections to see how I liked them.

First mock up still a little smaller then I would like. The carbon rod is used to simulate the approx. roof line.


Second mock up


I decided that the new back needed to blend back further. here is my first attempt.


I did not like how it was turning out so I redid it slightly smaller with a little more curve to it.

After I reshaped the back and before I broke out the epoxy and fiberglass, I got out the sanders and reshaped the front wheel wells. I tried to get it close to what was discussed earlier in the build.
Here is one of the modified wheel wells.


I removed the frame from the body and finished up trimming the openings on the bottom. I decided to cut one large foot opening instead of two smaller ones. I will eventually make some covers for of the chain line openings.


Next more fun with epoxy

Today I prepared the inside of the tub section for a layer of 9 oz fiberglass cloth At locations where I cut through the tub I beveled back the foam so I could get the inside layer of fiberglass to attach to the outside layer of fiberglass. That will stiffen things up nicely. I also added 45 degree bevels to the inside corners so the cloth would lay better.

Here is a picture of the inside of the tub just before I started to place the fiberglass cloth.


Next I lightly tacked (with spray glue) the fiberglass cloth the the inside of the tub. At this point I ran out of 9 oz cloth ( I ordered 15 yards to begin with) so I will need to order some more to the finish up.


After I wetted the cloth out I placed some weights to make sure the bottom of the tub would be flat against the work table while the epoxy cures. This should keep the bottom of the tub flat. The table is an old kitchen countertop on some saw horses.


I will order some more cloth tomorrow to keep the project moving along.

Man, that's awesome looking. By the looks of it, you might be able to rival the Cannon in his Quest. :) So, about the U-joint, I figured out what "small" item I'd like in trade/barter for the U-joint. I think you can guess . . . :)

Ok I will bring one of the small steel angles I used for weights in the picture I think that is what you are refering to for trade, right? I will not be bring the body to Indy this weekend still to much to do on it.

Rick has several of those small angle weights. I think they fell off a bridge somewhere...

Rick,

Sweet work, thanks for your continued sharing. Putting all the 45 deg bevel pieces on the inside is a great idea. It's hard to tell from the pic how much rounding you did to the aft part of the wheel well. As was noted earlier in the thread, you may want to round the bottom leading edge of the aft part of the wheel wells for the same reasons.

Thanks for looking and offering your great tips. As I was modifying the corners of the wheel wells I rounded them as much as I thought would look good. This is not a Battle Mountain vehicle, but hopefuly a daily driver. Please keep offering great sugestions.

Are you also going to be clever and mould your lights and rear view mirrors into the body now too or will they be predominantly surface mounts?

I do not want to be accused of being clever but at this time I have not thoght about those items yet. We will see once I get it opperational where everything needs to be. I should start looking for some mirrors that will work. Maybe something like what is used on the Quest.
