Introduction: Crankshaft Shop Stool
This one isn't too challenging, but it sure looks cool and I always get compliments on it when guys come over.
The crank was left over from a 383 stroker engine build and it seemed like such a waste to toss a good part, so I tripped over it for a couple of months until the neighbors threw out a kitchen stool on week. Then an idea hit me.
Step 1: The Whole Ordeal
3x Adjustable feet
3x nuts to fit feet
1x bolt that threads into crank snout
1x Stool seat top
1x something to mount seat to crank (I used a 6 1/2" saw blade)
First, I threw the crank in the sand blaster to get 40 years of grime and grease off of it. I had some adjustable feet off of an old washing machine (for a firepit, I'm sure I'll make another instructable about it in the future), but you can just as easily get a set from a scrap yard or local hardware store. I used 3. So I ran to the hardware store to find a nut that fit the threaded portion of the feet, and also a bolt that would fit the "snout" or hub area of the crank. I'm sure that somebody makes stool mounting kits for DIY'ers like you and me, but I had an alternate solution.
After inserting the feet through the holes in the flexplate (flywheel, for those of you with shick-shift cranks), I threaded the nuts on tight and welded them to the flexplate. The the feet can be adjusted to set the height.
Note: on my crank, the flexplate to crank bolts protrude past the ring gear and made it wobbly without feet. You may not need feet, or may not prefer adjustable feet. If you don't have access to a welder, using nuts and lock washers top and bottom would do the job just as well. We use the tools we have been provided.
For the top, I threaded the hub bolt through the center of an old used circular saw blade that happened to be a little smaller than the inside diameter of my stool top. Then, I put a handful of screws through expansion holes in the blade (you may have to drill holes, my blade had some already) to hold the stool seat on. Where the seat contacts the hub nut, I drilled a relief with a spade bit so the seat would sit flush on the sawblade. (Sorry, I really don't have any pics of this part). If you want you can reupholster the seat with your favorite color, or iron-on a decal for your favorite car or racing team. Be creative, it's your seat.
