[Well, uranium would be about the same specific weight :mrgreen:
Die steel would do anyway. You might need a bit more, but there´s enough space under the seat.
During early flight testing of the Boeing 747, wing flutter was detected. The solution was to add weight to the engine nacelles. From 1968 to 1980, about 600 to 1100 pounds(per airplane) of depleted uranium was installed as counterweights in production aircraft to solve the issue. I believe the weights were substituted with tungsten over the years. :o

Now that I think on it, I'm sure my aunt's Chistmas fruitcake would outweigh either lead or depleted uranium, and having it sit under the seat for several years might improve the flavor and consistency ...

PS - have to take a break here - my therapy after the accident didn't include bending over a motorcycle with wrench in hand for hours at a time. <G>

I always put a connector in. Sometimes a plug for trailer hitch but must of the times a 5-pin automotive one I can source easy.
On all my rigs I have to tilt the bike from sidecar to do the service. It´s comfortable if you just can plug off the electric lines
So noted! I'll put the connector on my to do list. Looks like I'm going to top out with six new wires, so a standard 6 pole trailer should do the job.

I will say, the floor keeps getting further and further away. I wish I could tilt the bike up on the sidecar too when wrenching on this and that. Or maybe invest in a lift. I've got a Laren jack here that's set up for a Royal Star - maybe modify that to lift the Ural. Almost the same weight, but I expect balance would be an issue. Worse comes to worse, I've got a chain pull that I've been known to use for changing tires and such. No rush there as most of the lower work is done now.

Well, lifts for rigs are a bit pricey. But if you have to work often on them (like I do in my shop) or if you´re handicapped, it might be a good investment.

In my shop I take the sidecar off the rig and then use a lifter for solo bikes.Talking about Urals, this can be done relatively easy with two adjustable center jacks. (one under each lower joint). By turning them up or down you can adjust sidecar to the bike without having to lift something by hand.

If I have a rig with reserve gas tank in sidecar and lots of electric lines etc, I place two lifts side by side so I can push the rig onto this pair of lifts and work on. I don´t think that´s an option for you. For my use a wide lift for rigs does not pay, so I keep it simple within my scope.

Ya ... I don't have room for anything too major here, so I'm eventually going to try to modify the Laren lift I have. That, along with a couple "custom" wood braces AND the overhead chain lift made for a real stable work platform on the Royal Star, and should work with the Ural. Once it's in the air, I can probably use the scissor jack I picked up for the road under the sidecar axle to level the load.

Just picked up the ULTIMATE ACCESSORY ... a crash test dummy for the car ... <G>

PS ... anyone ever try one of those inflatable bag lifts on a Ural hack?

How is it going; are you making any progress? We are rooting for you, and look forward to some photos of you riding and not just wrenching!

Nice timing. I just got done putting together a slideshow for an amputee support group I attend regularly. The hospital's "adapted bike" specialist had been trying to talk me into a three wheeled ebike instead of the two wheeled fat tire I'd been thinking about, and she's scheduled to give a talk tonite. I'll surprise her with MY three wheeler.

"But ... you TOLD me to get one??" <G>

Here's a link to the slideshow - let me know if it works for you or not. I tested the web version on my laptop anyway. It auto advances every 10 seconds, but you can hit the pause button upper right to stop the show, then hit run when ready for the next slide.

Most of you have probably seen the basic mods already - tank shifter, foot box, VW damper, etc. Only major additions here are brake mods to get the pedal higher and out from under the jug, and extending the rear brake arm for better leverage and less travel before they bite. Also added a heel rest. I also had to modify the sidecar linkage to adjust for the new pedal position, but it's working slick. That all took some serious cutting and welding on the stock parts, but happy to say no major dOH! moments, as it all came together nicely, and I didn't burn the garage down. I expect I'll have to do some fine tuning once I get it on the road.

I also did bar risers to set them back and up a couple inches for less stress on my replacement shoulder. The saddle seat is more for creature comfort. Adding a LOT of running lights, backup beeper and light, a headlight modulator, Back Off module for the brakes, and 130db horn. At least I'll be able to blind and deafen the next yahoo tries to run me over.

Anyway - still a work in progress. Here's what it looked like a couple hours ago.

Think of the fun you could have with that - put signals and a horn to make it street legal and just do laps around the interstate of major metros during rush hour ...

Updates:

Finished the seat mount today and right proud of how it turned out seeing as how I was pretty much slapping garage finds together to make it. Almost looks like it belongs there, and gives me a seat height pretty much equal to stock.

Image

Just gotta bolt the seat on to the bracket and it's done, but I'll hold off on that until I finish most of the dirty work. That seat is just too darned pretty to screw up, right?

Image

Also tweaked the new brake pedal setup. That's extended to clear the jug, and I added a heel rest using the "volunteer" left foot peg rubber that was no longer in use. Waste not, want not. A neat trick on that, courtesy of Shawn - ground down the end ridges on the rubber so I don't have to be right on for foot placement.

Image

Slowly but surely ...

Progress report, with possible screw up?

(oooh ... bet that got your attention) <G>

Got the car fender lighting done. Pretty straight forward once I figured out the wiring. I think it looks pretty slick - Larry the Dummy thinks so too. The reflectors in the old tail light mounting holes are temporary as those will be filled eventually.

Image

Here's where things get interesting.

Image

Got the left side hooked up and working on jumpers, but had to cut the rear grab rail off to clear the new light - as expected - forgot to mention that was the plan earlier. Anyway, I don't think it provides much in the way of structural support, and if necessary I could replace the loop with an internal flat brace under the fender between the existing fender mounts if it's going to be a problem, but it looks and feels sturdy as is. Certainly won't see the extra load of a passenger as this is a strictly solo bike. Might actually be worth another topic here?

Still needs the sidecar lighting wired up, and various marker lights at strategic points. Oh, and relocate the original left rear turn signal to the sidecar. My checklist of things to do is getting shorter!

No need for the rear grab rail... I had to cut this one off as well to get the rear light mounted. Keeps going since 2011 as a commuter
Fender is stiff enough. On solo and on rig, doesn´t matter.

Good to know - Wasn't all that worried, but nice to see someone else has been there, done that.

I see you also cut yours further in and tapped for new mounting holes in the fender. Looks a lot cleaner. Think I'll do the same here. I may still fab a new grab rail or short sissy bar that comes up behind the police saddle, but that's a project for later on when everything important is done. Been busy with gardening and a couple other projects here, so work on the Ural has slowed a lot, but getting there. Get some interesting curve balls every now and then - hiding the wires for the new tail lights turned out to be a lot more complicated than expected, but I got it done.

Now that the left foot box, handlebars, and seat are done, I can actually get on it! The foot box is long enough I can get both legs on it to make stepping over the saddle easy enough. Had to make some changes to the rear mount on that and nice to see it can handle my weight without any sag or flex. Running out of excuses to fire it up and go. Gotta admit, I got cold foot every now and then thinking about that first ride. My Evel Knievel moment, right? <G>

PS - your 2011 custom is one clean machine. I may have to steal (er ... borrow) a couple ideas from that!
