Hey Conrad, looking good I have two suggestions hope you don't mind.  I see you attached the front shocks using the pass through bolt similar to the Tumbler's original. But the shock mounts being so small expose a lot of the bolt shaft to stress....You may want to consider some side brackets to help shoulder the stress on the bolt instead of using a single steel plate. It looks like a grade 8 bolt but that's still may too much stress put on the shaft of the bolt.

The doubling up of the shocks will work great during the compression stage of operation[ as you hit a bump] but you may have a problem as the compression is released taking the weight off of the front end.....You might want to consider a secondary shock absorber under the control arm to handle the release of compression.

Another option on the engine and especially lack of space, heat generated by an engine and gearing issues might be to use the rear axle from an electric golf cart. These used golf carts are readily available and the electric motor runs parallel to the axle....Just an idea.....Project is looking great....Keep up the great work....Dave

Great Shagg! I'm having lots of fun learning as I go!  It's people like you and the Mrs that keeps me motivated!

Thanks Dave and yeah I was thinking about the bolts and was going to ask for thoughts on the mounting. I can't wait to get another pair of shocks and see this thing sitting on it's own. I'll get an idea of how the front end will react. 

Works going to stop for a bit as my vacation ends and work begins. Back to the hum drum 9 to 5 of information technology and corporate america.  Hum drum compared to the week I had!

you could also use a jounce bumper to slow and stop the arms in full extension. It wouldn't be as smooth as a shock but would do the same job, and I bet you could get a couple at the salvage yard for just a few bucks..... just another option.

Hey Chilebean, sorry I'm not familiar with a "Jounce" bumper unless that 's the same as a bump stop. A solid rubber or polyurethane stop that prevents the suspension from over extending. Unfortunately it does nothing to slow down the suspension.  Shocks for a domestic car are like $15 brand new. Even with shocks limiting the suspension bump stops should still be used to prevent overextension. King shocks have the bump stop incorporated in the shock....

Also if you get another pair of coilovers even if they look the same they may have a different spring rate due to wear and tear. So you may want to consider putting one of the new shocks with one of the used shocks to help compensate for that difference...Just a thought...

Another option on that shock mounting bolt would be to remove the rubber sleeve at the end of the shock and slide a piece of steel pipe through that. Redrill the mounting plate so the tubing can slide through and run it through the second shock then run your grade 8 bolt through all of the tubing to hold the shock ends. As the control arm moves up and down it requires the shock end to rotate slightly with the tubing.

On that original Tumbler design the vertical shock plate with the bolt holding two shock ends is a weak link as well as the single plate welded to the control arm. Breaking at either point while cooking down the road could cause a catastrophic failure.....Just a suggestion....Too bad you have to go back to work at the rate you were going you would have been done by month's end....Dave

Dear Conrad, that is amazing work you are doing there!, and I thought my batmobile go cart was alot of work! I have a couple of questions. From the full scale tumbler, is yours a 1/2 version or 1/4 version of it and is yours going to be a one seater or a two seater.

Thank you! This little guy is about 1/2 scale i think.I do have plans to build a full scale one but it seems like the shop I thought might be helping me may not be ready.  Don't know if they'll ever be but for now I am enjoying the learning experience.  This mini-me will be a one seater.

Hey Shagg...someone told me it's possible to add reverse to an engine like that Honda...I can't see how...

the only reverse i've ever found is a steep hill (go down it backwards) or stick foot outside and push backwards. But i'm not saying it cant be done, i've just never seen it.
