Normally I wait until the project is done but this time, I'll show it before, during and after for giggles.
This is for the guy who has everything, A BIG SPARK PLUG. People will say, why make a big spark plug? I say, why not? Add to it that I'm a little off my rocker so should be good times.
This will be modeled after an actual R45 spark plug that takes the 13/16 socket. (wanted old school stubby sytle) You would think a car guy like me would have an extra of these lying around but NO, I had to remove this from my 69 Chevelle! Seems I have tons of the smaller 5/8 plugs around but none of these. Oy!
Ok, getting back... as the photo shows, I have taken measurements with a digital caliper of the real plug in decimal inches and then I am multiplying those numbers by 53%. Yep, it will be 53% larger and will be kept very, very close to that size. I made some dial indicators mounts for my lathe recently shown here: http://www.348-409.com/forum/threads/metalworking-project-dial-indicator-mounts-for-a-small-lathe.35347/ so this will be a great project to try those out and to hone up on getting accuracy from them.
The photo shows an 1-1/4 nut which will be the size of the plugs hexagon area. Next to it is the blank I started working on which is 4.034 inches long and 1-1/2 inches in diameter. The part turned down some is from the bottom of the porcelain and up.
Well, that's all for tonight. I'll post the progress as it goes...
