When my old big money Snap On creeper died, basically the wheels failed mainly,
I had a brainstorm {or brainfart maybe}
I couldn't find anything I liked or that was what I wanted that wasn't $250-$500 or
some ridiculous amount of $$$ for a damn creeper, so I made my own...
I took another cheepo one $69.99 Grand Auto POS I had from a long time ago &
made it a low rider & made external outboard side wheel pods
with 2" x 1/4 flat stock I bent 4 of them up in the vise & added some gussets
to lower the main body, using small outboard ball bearing wheels,
along with some added tool trays, 1 above my head & 1 on each side
for when I was working with jack stands,
It helps to keeps you away from fluids/stuff better/lower too, off the damn floor
{you can see where the old org. wheels were, underside photo, it was about 4"'s taller},
it gives you places to store my/your hand tools, wrenches & air ratchets etc.
I should have put bigger wheels on it, but works really well except for,
with larger wheels {pneumatic too} would no doubt make it easier to go over stuff...
anyway a couple hrs with a welder/grinder & some scrap metal
{maybe some store bought, larger wheels...LOL}
you can/could do wonders...
Never knew how much the simplest things, like a couple of tool trays,
one above my head rest & one on either side,
it makes things on your back way easier,
way less getting out from under the car or
searching for tools that you ultimately will run over
or scattered under the car, just when you have one hand occupied with a task &
always seemingly will need another wrench or tool etc.,
wallah shazam it's right by your side or above you head in easy reach...lol
I could be improved on, I will someday, but I've used it for well over a decade now...
I also use a big piece of cardboard or carpeting remnants, from time to time too,
I prefer not being on the floor thou, sometimes you need to do what you have to do...
I'm getting way to old {too stiff afterwards} to be on cold or hot concrete,
all damn day too...
She's a little rough, thrown together quickly/hastily,
but she gets the job done, really close to ground level too &
not being on the floor, saves my old bones too !!
My new shop will have a lift again...
