I needed to ground the carb in order to have the electric choke work, etc.

Had only ring terminals with 1/4" hole, needed 5/16 hole.

In the past, trying to drill a ring terminal results only in a mangled terminal.

Clever trick here is a jig
Scrap wood
slit with hack saw
hold terminal with 1/4 hole up to wood, mark location, drill wood thru with 1/4 bit.

Put terminal in slit, using 1/4 bit to center it in the new hole

clamp wood tight as you can with e.g. Vise Grips.

now carefully drill thru with 5/16 bit.

Worked out great.

You do have to have a meaty enough terminal to start with of course.

Why not just get the right terminal? But I do understand as I gotta go @10 miles one way to get one.

 

You can also enlarge the I.D. of flat washers and ring terminals with a Dremel.

 

I've seen a similar trick using a split block of drilled wood and a razor blade to make a jig for slitting fuel line to make tubing shields. Makes sense if you're good with wood.

 

ok,now i have the idea for making a tool to strip the coating off wire thats being scrapped. thank you

 

Good with wood?
No complaints yet
:-)

At this facility, a parking and storage garage, I have only what tools I bring. Lucky to have a 5/16 drill bit. The long drive to a store that may not have what I need would take longer than the process I used. And cost a lot more.

"tool to strip the coating off wire thats being scrapped"

Aye, I have done this at work to slit plastic tubing. Same concept would work for wire.

Hole thru wood suitable for your tubing or wire.
Secure small block to the holey main wood piece, with razor blade secured to it. locate blade appropriately. Hinged spring loaded razor blade may work for wire coatings. Insert wire or tubing, get it started carefully, then pull it on thru. Motorize it for looooong lengths.

 

I take a 1/4" or 3/8" rattail file and put the terminal on it and a few quick spins and your ready to go.
