air compressor

[Meir]

so i ended up getting this baby:
Amazon.com: Bare-Tool Makita BTW251Z 18-Volt LXT Lithium-Ion Cordless 1/2-Inch Impact Wrench (Tool Only, No Battery): Home Improvement
this thing work awesome. was afraid it will be too weak, but this thing will take a wheel lug without hesitation. the bolts of the cross bars are not even a challenge. at this point it will be perfect for me.
better compressor maybe in the future.
now for my question.
the mid rise lift i order back in August will be here tomorrow.
this is the one:
Automotive Scissor Lift
looking at the description, the minimum height is 7".
anyone have a nice idea how to build a ramp that will be easy to move aside once the car is lifted?
i remember seeing a post, but cant find it.

thanks.
