what CAD software are you using? Looks like a good project!
You'll need bushings, or bearings, or something if there's play in it. But some material mates up really nicely, and you wouldn't need a bushing. I don't know if there's any materials that are that size that fit together that well, but you might look at some ID and OD size charts.

I'm making the rear suspension now, so more pics later.
I've read of people using pvc with holes drilled to hold grease. good idea?
this is also an area of concern. will it hold up?
where would you recomend adding brases? this is where I thought it would be good, and easy to get in and out

Lovely cad work there, wish I could produce drawings like that.
If you can get hold of the new Haynes book build a sports car on a budget. Why not take a look at the suspension set up on these for ideas.
Use a library if needed to read the book, there was also an older version that may be out of print.
Guess what my new project is!
Go-kart anyone?

Where did you read about PVC? Sounds sketchy.
The area in question about holding up: maybe ... matters what the material is, but I think that i'd brace the crap out of it. maybe even some 1/4" plate running down that whole length...
Heres the rear suspension with braces. I'll add gussets to the braces too.
should I use the same method of bracing up front?
bottom is toward the front or on the Z/blue axis
here are the dimensions (same as front suspension) should I change them somehow?

pvc bushings will work...
I've run the PVC without grease fittings(greased every few times a year), if you buy a bolt thats long enough to not have threads on the pvc(chop the ends for apearance if you choose) it should last 2-3 years, mine did on another project... if the pvc sits on the pivot bolt threads, a season of riding perhaps, but it might be sooner depending on how much you ride. when the PVC wears out, it will get sloppy quick and if left unfixed will damage the metal parts. this is the reason most people have bad experiences with them, IMO
You can get urethane bushings online from advance auto parts that will fit into pipe/tubing (using the black water pipe I had to sand the lip on the bushing a little). do a search for universal bushing on their website http://www.partsamerica.com
I'd go to http://www.energysuspension.com/pages/sk_bsp1.html
and choose which one you like (go with the 9.8113 style, they are halves, MUCH EASIER for you looking at your setup) goto advance (partsamerica link) and order them, around $6 a "pair" (2 full bushings, or 4 halves) you might be able to get them ordered at a local store as well
you could also get 9.8107 and cut them in half, that would be less diameter if you need it.

This is what I'm hoping for, although, finding 13 long bolts might be hard.robert said:
I don't know what to do with the short bushings ryf suggested. since the whole thing is 12" long, AFAIK I'd need 12" long bushings
What issue?
The only problem I'm having is not knowing what to use for a rear hub. I was thinking of a .25" steel plate with a bearings in the middle for the axle shaft

you could buy any of the ones with a flanged outside edge and cut them in half, then turn down the inside to get the desired diameter (slightly larger than your tube/pipe. the lips on the outside edge will keep them in place. I used 9.8112 and if you leave the lip as is, it will not fit inside 1" black pipe, cutting it as stated, and turning down the middle section into a slight wedge shape will allow it to be hammered or tap into place (leave a flat spot for binding and to make sure it goes straight. tap them witha hammer and a buffer board.
or you could use the two I mentioned that are already large wedges and it will self align (put them on the end of the pipe)
I turned them using a bench grinder and a bolt, wear gloves and let it spin against the wheel, it will go quick so watch and check often. good luck

uploading them is fine. they get automatically thumbnailed and there's plenty of space.
Are you linking to them now?
about the hub: I still don't understand how you're going to keep the chain from falling off. Maybe i missed a post or something.

yeah, I'm uploading them to photobucket and them linking them.
I'm gonna have a cv axle or something similar going to the wheels, and the sprocket and caliper are going to be in the middle of the black box. something like this
Now only to know where to get those bearings

that thing is the definition of badass, how much has this project put you back in materials minus the tires and motor?
