Could someone please explain or give us a link to a site that explains thread numbers? I grew up with Imperial threads but that was 30 years ago. Adaware asked the question but the answer by stevehuckss396 just gives the metric equivalent but doesn’t really explain it (no criticism meant). I’ve just spent nearly an hour looking for the answer but with no luck. I googled it but it seems that computing and internet threads take precedence over physical threads.
I realise the last number is the threads per inch but what do the first numbers mean? (eg: #8 or #10) Is it like gauge numbers where the smaller the number the bigger the size? I looked at gauge numbers but they don’t seem to line up with “#10 = 4.82mm” so I really don’t have a clue.... Does this relate to all (american) threads or only Spark plug threads? I even checked out NGK's web site but found no help.
thanks in advance.

A number zero screw has a shank diameter of 0.060"

Each screw number larger increases the shank diameter by 0.013", up through #12. After #6, there are generally no odd numbers.

Thanks guys! This place is awesome for the body of knowledge of its members. The bit of info I was missing can be summarized by:

The thread numbering system is a system that fills the gap for all imperial (inch) threads under the 1/4" size. #12 being the first size under 1/4" and #0 (probably) being the smallest on offer. The second number being the TPI and the first number being just an assigned number with (as Tom said) each screw number larger increases the shank diameter by 0.013", up through #12. After #6, there are generally no odd numbers.
Once again, thanks guys!

and #0 (probably) being the smallest on offer.

There are smaller but harder to find. I have had the need for a 000-120.

0-80
00-90 .0350
000-120 .0260
0000-160 .0155

Hi Mick
Have you sent the plans for the V8

I have been playing around and I think I will try to reproduce the Engine on http://www.weberprecision.com/. I have modeled the pistons, rods and working on the block. I am just designing as I go so we will see how it works out.

What size bore and stroke are you going to make it? Will it be big like the original weber?

[eartaker]

Right now looking at a 1" bore 1" stroke giving me 6.28ci or 102.9cc.

Thanks Steve. Keep it coming!

Cross lifters off the list. Both sets are complete. I am hoping to get back to rockers this weekend.

[eartaker]

Wow that is awesome. how long did it take to mill that block down and what kind of mill did you machine it on?

Hello everybody!
Finally managed some progress this week. I spent the weekend at the Detroit Maker Faire so today I almost finished the intake manifold. First thing i did was drill the mounting holes thru and then spotted the passages with an endmill about an eigth down.
　

　
Finished drilling the water passage and the fuel passages on both sides. The vise is tipped on a 5 degree angle.

　
Wasen't sure about this one but i used the new angle blocks to tip the part at 68 degrees. I was a little worried but it worked perfectly.

　
Then I drilled to intersect the fuel passages both forward and backward.

　
　
Bolted it on the block to be sure it fits. The only thing left is to drill the distributor hole and finish threading a few holes and it should be a keeper.

The valve corvers took forever.
