Mikuni Mouse- Computer Mouse / Carburetor Hack

Picture of Mikuni Mouse- Computer Mouse / Carburetor Hack
I had an old carburetor I was cutting up to make a cutaway out of, and this project just kind of fell out of my brain and splattered on the table...  Why not take the other scrap part of the carb, and turn it into a MOUSE for my computer!?

That was literally the extent of my planning.  Next step: have at it with various sharp instruments!

Supplies Needed:

1 carburetor
1 working mouse
2 rivets or bolts to use as buttons
Misc. nuts and bolts
Sheet metal for base
Scab bicycle tire tube patches or other thin soft anti scratch material

Tools Needed:

Milling Machine
Drill or Drill Press
Marking tools- awl, marker, ruler, etc
Additional metal cutting tools- aviation snips, notcher, punches, etc.

Step 1: Cleaning Parts

Picture of Cleaning Parts
When cleaning carbs, I have settled on a process I thought I would share here.  Turns out Pine Sol makes an EXCELLENT aluminum cleaner and degreaser- so I soak the entire carb, disassembled, in a vat of it for about 24 hours.

Once the carb has soaked, rinse with warm water.

Next, using compressed air and carb cleaner, clean it all again.

Finally, spray all the parts with WD40 or another light oil, and reassemble (except... we are going to cut it up some more!)

I really enjoy seeing good uses of old gear. Steamy!

Well done, very sideways thought out!

Beautiful job, VERY steampunk, even with the grey colors (easily remedied). now fix that scroll wheel and make the whole thing more secure.
Looks great, but it will probably be tough on the desk.

So far it hasn't scratched anything. The metal of the carburetor doesnt actually touch the desk, and when I made the sheet metal skid underneath I bent all of the outside edges up just a bit so no sharp edges contact the desk. I do plan on putting some contact pads underneath it though just to be safe...
forget the tube patches: they'll drag HARD. Get some Teflon tape, won't be cheap but it'll glide like butter in a hot skillet.

Very awesome. This would kill my hand ergonomically but I love the design and creativity way too much. Nice job.
