HELLO ALL! Well for some time now I been working on a Tumbler build.... Worked on it for a while before I stumbled across this site and was amazed by everyones work. I've been spending a lot of time researching how to get one of these bad boys built. I should state a couple things first.... I'm very good with my hands and I'm very good with computers. With that being said I'm pretty average with cars (but I do have people close to me who are car experts) and pretty bad with Sketchup. Not sure what it is but this program and I are just not on the same page... I wanted to post the pictures of my chassis so far and get everyones feedback. At least find out if I'm way off. I'm a perfectionist so its probably not a good start that I'm somewhat frustrated with this chassis. Also, ignore the center of the chassis. My frame was in half and I just combined them to throw them on here.
I made the chassis so it would fit into the sketchup Tumbler. I can see its going to be very difficult welding this guy together because of the pieces not all angled the same. Good news is my bro is a professional welder .
As far as the dimensions are concerned, I want it to be street legal. I made it so the width would be 8 1/2 feet. There wasn't much room left for the engine so I have the length at just under 15 feet.
I would really like to have this planned out 100% before I begin to start building. I know it wont go according to plan (It never does) but its the only way I'm comfortable in doing things. Does anyone have any specifics on steering and suspension? I saw how Conrad did it on his cart and its great, but I would really like to know the names of all the parts involved. Any additional information would be great! And I'm prepared for beating on my build so far so let me have it...

Looks great! Thanks for sharing your progress and your measurements! I'm also in the process of working out the chassis for a street legal tumbler. May I ask where did you get the sketchup file for the tumbler? I'm currently using Solidworks and would like to find a somewhat accurate model to import in and work from. I'm pretty new to Solidworks, and its a bit more complex than Sketchup, but there are some features like "sheet metal" that I want to use to help me work out the panels whenever I get to that point.

I found it here: http://sketchup.google.com/3dwarehouse/details?mid=9b859dc6ddc6b5dc6f48b04a2541e8a9 Im 99.9% sure that it is Shaggy's design. Sweet, you and I will have to share info on Street legal models.

I like how your planning is coming along. Are you going to setup the engine the traditional way? Or face it opposite with the transmission pointed back?

This is how I've planned it so far. I have not confirmed this is the best way to do it with my experts yet. Im not to keen on having the engine next to the driver. I also would like to know the advantages of having a V-Drive transmission. I asked one of my friends if he thought having the trans right there by the differential would be a problem, but he said it doesn't matter. We didn't get into it, but assuming I would have to get a extremely short drive shaft.
Also, the engine in the pic is Chevy 350. I read some people recommend using truck parts. Just curious if anyone has any suggestions for a smaller motor, but I don't want this guys top speed to be 45mph LOL

A V6 can be bumped up to 250 horse without too much work. You can buy a full size truck with a V6 in it with about 190 hp, so the possibility is definitely there. But will it have enough torque to turn those big tires?

Hey SuburbanKnight and Lilboatsman. Just wanted to chime in if you don't mind. I like the inline configuration better than the reverse engine design myself. I think its important to worry about the size of the engine as there is a lot of spinning mass on those wheel. The 44inch TSLs with steel rims run about 150 lbs each and you have four so 600lbs in spinning mass. We know the carbuerated 350 Chevy engine with an automatic engine was used with the original Tumbler. There were many vans that used these engines where you sat right next to them. Race cars use a scatter shield over the transmission to protect the driver from a possible tranny explosion. This is going to me necessary because the engine configuration has got to move forward so the end of the tranny is closer to the rear firewall. Shelby cobras have one of the shortest driveshafts at 13 inches so I wouldn't go shorter than that. Its also necessary to incorporate limiter straps to prevent the rear axle from dropping further than the combined angle of the two u-joint on the driveshaft. The worst thing is to have so much time and money in the v-6 and not enough torque to move the vehicle adequately. Hope that all made sense. Dave aka BWD
