Like the down tubes on the Bronco ?
Well they look funny but they serve a function ..... you decide, It's your rig

However
SWEET doesn't have them ..but no one said you have to make an exact copy

I love confusing you

Morten

Bart bender · 04-23-2011, 07:44 AM

I detached them and The Saundo and I decided that they just don't work on this rig. That EB on the first page is just SOO Bad ass. SWEET is the driver of the MB I am modeling? Morten I am easily confused

SnoopMaxx · 04-23-2011, 09:29 AM

The rig you are modelling this after is named SWEET
The driver on the photo is Håkan

mjderstine · 04-27-2011, 12:13 PM

sorry i missed this build man. this looks awesome. i cant wait to see the finished product. are you gonna stick with those tires for now? or perhaps get some padles?

i wish i had a welder! but i live in a condo. i can only use hand tools here. and a drill press.

nice nitro too! is this thing around 1/6th scale?

Bart bender · 04-27-2011, 03:40 PM

Thanks MJ. It's scaled down to 1/8 from the exact spec Morten sent me from the 1:1. Yah unless you have a garage with the Condo I would strongly say no welding

These tires for now untill I get finished and tuning and then come the Panther Paddle tires

mjderstine · 04-27-2011, 08:48 PM

3.2's? right?

i might be able to braze on my balcony, but that's about it...

slimm87654321 · 04-28-2011, 08:11 PM

its nice to finally see a foff tuber...its lookin good keep the updates comin

Cordwood · 04-29-2011, 04:15 AM

It's coming along nice, Bart.

What kind/brand welder are you using?

Bart bender · 04-29-2011, 05:41 AM

Yup, 3.2's. Height is bad.

Miller 180. One kick ass little welder. I'm used to a Shop Master 300 with a 22A feeder. All the power in the world. But this little guy I would HIGHLY recommend. And thanks

It's kind of dead right now. Spare time is at a premium.

Edit: sorry 180 not 185.

Thank you.

Hope to get some more done this week.

This is looking awesome... cant wait to in motion

cummins driver · 05-03-2011, 11:11 AM

Looks great man!

The only question I have is about the gearing. You are probably not going to want a 40mph top speed. Im afraid you wont be able to gear it low enough with the big tires and center diff, however, i dont know what the gear ratio in those axles is. I figure maybe 25mph will speed would be about right for FOFF, but thats just a guesstimate. Have you done any calculating on the gearing?

Looks great though!

Bart bender · 05-03-2011, 01:03 PM

Diffs will be 4.3 and the center will be 48t. The RG is a low end motor and with my 007 pipe it should make good power down low. The Panther paddles I'm gonna run are a lot shorter than the Aftershocks that I'm mocking up with. I do have my fingers crossed too

cummins driver · 05-03-2011, 03:02 PM

The axle ratio is a little lower than I thought it might be, which is good! haha I did some math for you using a 12t clutch bell. Lets see here.

48/12 = 4:1 x 4.30 = 17.2 final drive ratio

I have a calculator on my computer that i made in excel. Just plug in the tire size and final drive ratio and a certain engine RPM and it will give you wheel speed. I looked up the paddles and they are 5.5" diameter.

So I plugged in 5.5" tall tire, and 17.2 final drive ratio.

35,000 rpm = 33.3 mph
30,000 rpm = 28.5 mph
25,000 rpm = 23.8 mph
20,000 rpm = 19.0 mph

That should be about dead on your wheel speeds at those RPM. That should be pretty close to where you need to be. Hope that helps give you a little better idea and looks like you'll be alright

Maybe if you need to you can find a larger spur gear. I know they make them up to at least 62 tooth for some truggy center diff's, so if you decide you need to after running, you can still go with quite a bit more reduction id say.

Keep us updated man!

Bart bender · 05-03-2011, 07:21 PM

Cool little calculator you have there. Thanks for computing that out. Great name too

Hope to have my shafts tomorrow so I can finally get to the links.
