spark plug caps

I like the dressy look, copper and brass, but hate chrome. Brass has that old brass era charm.
 
Does anyone have a picture of a spark plug with the cap from Restoration Supply Co. installed? Would like to compare with pictures of spark plugs above.
 
Site will not let you copy image, the cap is smaller and costs $3.50 each, does not even come with the knurled nut.
I like the way these homemade ones look better
 
Yes Burner. I was able to grab a picture but was hoping for something clearer on a W18? And without that funky top? They are a bit expensive.

I agree, I like the looks of the homemade ones.

Hey Y-Blockhead, on making your own caps. How did you hold the caps stable when using a drill press? I don't want to mar the outside or bend them out-of-round with a pair of pliers.

Hi, I didn't actually use my drill press to drill the hole, just to mark center with a ½" drill bit. Sorry for the confusion.

When I drilled the hole I used a 5/16" drill bit and held the cap with my hand against my wooden work bench. The copper cap is soft and drills easily. After drilling I polished them on my bench grinder.
 
I really like the look of these caps. I'm on my way out to buy some caps at Home Depot. And these don't affect the plugs or the way the car runs?

Hey Marty. I actually thought about that. I have a 12v Pertronix Flame Thrower coil. I started my car last night in the dark to see if there was any arcing. I did put a little di-electric grease inside the cap to prevent moisture from collecting "Just in case".

But no, I haven't had any problems, just a fun thing to do. It makes the W16/W18 plugs resemble 3X plugs.

Thanks again for sharing your idea Bob-A.

Got the 1/2 in copper caps and made me a set, buffed and drilled they look good. I found small brass accord nuts at the hareware store and look fine, had to use brass washers. Can't find a way to post photo's.

thanks for the idea,

Well, I just finished putting my Spark Plug Caps on my car and they look great. This was a fun project that only cost about six bucks. The caps and the knurled nuts all came from Lowes. When I went to Lowes and asked if they had parts for a 90 year old car they thought I was crazy. Maybe I am.

Y-Blockhead & others,


I'm always willing to share my idea's with fellow Model-A'ers.;) No matter how scatter brained they may be.......:eek: My idea's not you guys!

Finally got my caps drilled and installed. To find center I used a center punch after marking the middle with an X with a fine sharpie. Then I used a very small bit in my drill press to get a pilot hole, then held upside down against wood with a small rubber jawed bar clamp to drill larger 5/16" hole. A rat-tail file to smooth burrs and a little Never Dull made for some good looking caps for very little price.
 
They are only penny's from the suppliers. Not worth the effort to mess about. I get mine from Bert's.

Bert's sells copper plumbing parts? I see the brass knurled nuts, but that is not what is being talked about in this thread.

Lighten up, people are having a little fun with their sparklers.

Neat project! However, I'm thinking the vertical length when installed should be shortened by one-half or more. Anybody agree? If you do agree, what would be the easiest method of cutting without damaging the appearance. Copper is soft.

I did experiment with the length but decided I liked the longer one better. When you shorten it the 'ribs' on the porcelain show and IMO it looks better with the ribs covered. The 'rib' do show on the 3X plug tho. The W16Y is a lot taller than a 3X.

But have fun with it and do as you think best.
