I was thinking of utilizing bolts in my design. My first idea was having temporary cross members from left to right to ensure the distance between the ramps are even and square (kind of like the pics in the Corevette site but adjustable for different cars). The second was to secure the two portions on each side so they act as one piece.

I like the idea of having the ramps bolt on to the main assembly, so that's probably what I'll do. But I also want the ramps to be able to be easily disassembled to store underneath my car when the whole system is not in use.

I thought about using some metal grates, but when I laid it out the slope is very tame. And I'm pretty sure if all 3 sections are bolted to each other, that ramp won't move because of all the weight and surface area which will be contacting the ground.

 

I would imagine that with the angle of the ramp coupled with the static cof of the wood/floor that the ramp wouldn't slide, unless you hit it at high speed in which case you would have bigger worries lol.

 

^^ +1. Maybe if I it at 88 mph I'll end up in 1955... Lol

 

Damn thats kinda IFFY. Looks like a great idea might make something on the CNC like this.

 

It'll be ok. CNC would sure cost a lot of money. If I had my own house, I'd definitely spring for the all metal & hydraulic route... But this will do for now.

 

You don't have to worry about traction on the ramps. The 30" pieces I mentioned above are not secured in any way, just laying on the ramps and I've never had one slide on me.
Remember, the rear wheels are pushing the car forward, too. Plus, it's not like you're going to be engaging the aggressively.

Once I had my ramps in place, I made a few marks on the garage floor with a Sharpie to reduce future setup time.

A CNC seems like major overkill of precision, not to mention time, for ramps.

 

Thanks for the advice Evo8. Maybe I'll make some triangles like rhino ramps which the 6 foot 2x6's will rest on. And maybe they can double up as wheel stops once the car is up on the ramps. I'll need to draw it out...

 

Plot thickens...

Will be back home on Thursday - Sunday and hopefully I can get them finished on Thursday.

Also, I was looking at Race Ramps online today and saw their $2800 price tag... I'm glad I'll be saving myself $2500 dollars

 

Which ramps are you looking at? their standard ramps are like in the $300 range

 

Portable Pit Stop

 

^ wow those are exspensive, plus seemed over priced. Good call on makin your own

 

I think I may do something like this when I get my evo back

 

Nice, good idea for doing exhaust work.

 

Got in today from Japan and started working on the ramp. I'd say it's about 90% complete. The last 10% is purely cosmetic and not detrimental to function. Will take more pics tomorrow when there's light out.

FYI. Wheel center to wheel center is just around 59 inches.

 

A few more pics...
