Unstealthy bomber : The Aluminum Overcast

[DeathBlade]

Well I'm on a new build, no more with RC builds I've stepped up to the cromotor v3 But onward.... (also noticed I cant spell aluminum for some reason) :lol:

I've loved the design of the stealth bomber downside I don't have the cash for one.
Now I love the design but it simply doesn't isn't made completely out of aluminum.
So here enters google, TechShop, corel draw, a cold cut saw, and a 72" hunk of 5" aluminum C channel and I have this

Then add a Tig welder, a hunk of 2.5"x.5 wall tubing and metal lathe and you have this.

Now if the tracking is correct I'll have a cromotor tomorrow and the shifter for the Alfine 8 speed hub I'm using as a jack shaft.
So tomorrow will probably be swing arm and jack shaft mounts.....


And a little bit of grilling.

Sweet setup!

Looks like you've got room for 2-3 more packs of dogs.

 

[DeathBlade]

Got the Cromotor!!!!!

Forgot the hotdogs...

Got to Techshop late and ran into a TIG class another 45min till there done so did some mock ups.

And got some work done on every ones favorite deathbot...

Got my rims in and tires in and the rims were a funky translucent yellow looked like a funky anodizing job must have been why they were $30 but a quick bit of powder coating fixed that little red wagon with some superdurable wet black now to lace some hubs.
Funk

Fixed

On the side note of powder coating, I had just pulled the rack from the oven and was admiring the coat and missed the fact the one of the rims swung into my arm
Hot things are Hot!!!

welded on a lip on the side to cover the edge of the side plates now for even more diamond plate!!!! muhahahahah!!!

Shown next to a injection molder for scale, well scale if you know how big out injection molder is.

12v waterproof LED modules I have a few dozen if anybody wants any their $16

Haha, i used that exact injection molder in college...

 

[Fidel]

I loved your work.

Nice one!

Whats the plan for the swingarm?

Nice one!

There is no plan! I building when I get to it

No really I have a some 2x1x.125 aluminum tube and some 1.75x.75 aluminum bar for the drop out and that will get a .25 thick stainless inset to keep the axle from torquing.
Biggest thing I have to do is figure out how I'm mounted a Shimano Alfine 8 hub as a multispeed jack shaft, Since the actual bomber gearbox is near unobtainable.

Patterson drive?

Wow, been a while and not much progress till a bit ago. Found my first fork wouldn't fit my moto tire.
So I bought what the ebay seller called a kz100 fork for $100 when it came in it turned out to be from a kz250 or 350 (if anybody need a big fork tell me)
So enter a couple of months of doing nothing and ebay trolling, till I got a honda fork from a cr80 a actually one this time for $50

Downside it needed new bearings and I'm a cheap ass on the wrong parts.
Seeing that the CR80 used a 26mm bearing which really wouldn't fit my headstock which I bored for my DH bearings. I decided to turn out the inner races on some 1" trailer bearings.... How hard could they be... well thank god for carbide lathe tooling. But extra downside my headstock was still to small for the bearings so I had to get to some creative mill fixtures to get it bored out.

Then started working on the swing arm machined some drop outs out of 1" aluminum with a pocket for a stainless anti torque insert.
Along with a mounting bar for my new robots chassis.

fresh off the flowjet some 3/8" 304

The anti torque plates toke some persuasion to break the tabs so have some sanding to do, here one of the plates in mounted in one of the drop outs, along with the new headlight.

Got one of the 24fets from lyen.

still need to get the aluminum to mill for the swing arm/jackshaft mount, along with a rear shock but.

On a side note where do you guys think I should mount this horn on my jeep? I can go along with passenger frame rail or sideways behind the bumper.

 

[GiantEV]

That's the same headlight I use. It's nice and bright.

 

[DeathBlade]

Finally getting back to working on my bike!
Got a one of Lyens 24fet 1ok monster controllers
Got the cr80 fork mounted and welded up my rear control arm
Got a set of 203mm rotors and milled of the rear to fit the cromotor case pattern so I have more room for the wires.
Now I have to get brakes I was thinking maugra MT4'w or MT-S, for formula the one, which one s would be the best?"

Got my pivot ready to weld, but big gaps so I built a convertor to put a hobart/miller spoolgun on a lincoln powermig256 (also my onboard welder on my jeep)

Finally a good mockup, now to just get my shock and make the seat and shock mounts

A little scissor lift I'm making for my robot.

 

[DeathBlade]

I'm ordering brakes now, I'm trying to decide between these three.

Formula RX
Magura MT6
Magura MT7

Any other suggestions would be helpful.

I have no experience with this (I should just post that phrase in my sig), but...mount your rear brake disc to the Cromotor, and then take it to a high-end off-road bicycle shop, and have them test fit the calipers over the disc. Maybe all of them will fit, but if one or two are too wide on the inside of the disc, that will narrow down the choices. You may even find that variable regn 9 afeature on some controllers) will make a valuable magnetic brake on the rear wheel (keeping the pads cool and long-lasting).

also, consider this:
