Nice number plate!

I'm testing-out these 1/16" tag rivets which have the right look and size as original, but I think a true rivet which is peened-on real tight would work out better under vibration. I'd hate to lose one of these nice Terry Sullivan name plates on the track. Tom Smith is looking into a source for 1/16" alloy rivets which will sell smaller quantities than a million per box. I've also found sources but you end-up with hundreds more than you need.
I really think the head size in these tag rivets is just about right. I got them from LoveLady hardware in Torrance Ca for 5 cents each. Head diameter is .120 and the shank is .070 right under the head and the end starts at .062. Shank length is a very short .142
I used a .060 bit in a pinvise to carefully drill thru the name plate and a dremel to drill thru the shroud. It's a very tight fit using these spec's but haven't completed pushing them all the way thru to see if I can peen the end down a bit like a true rivet; they might be too hard. First I have to remove the adhesive backing paper and then there's not easy turning back. Will post more pics when it's done.
Terry has done a killer job on these name plates where they look like they belong on some high-end product/jewelery. You could just stick them one and forget about all this hassle I'm posting about.

Grainger also has 1/16" aluminum rivets in several lengths and head types from Hansen rivet right here in the USA.

Looks like quantities are 1000 though for about $15.

I didn't know what Mac used originally but I chose 3/32 because that was the size of the holes in the Mc10 shroud that I had for one of my engines. All the others were not drilled. It isn't a big deal for me, I am not a purest.

Scott,
Thanks for the spec on an original rivet hole size. I only had pictures of original motors (pic attached) and found something with the best looking head no matter what size shank. I'm not a purist either, but looking back at all my decimal measurements shows I do get "Detail-itis" Just thought it might help others and inspire them to give other options; Just like you have
I didn't know (or care) what the shank diameter McCulloch used since all my shrouds were not drilled yet. But it is nice to know 3/32" shank size was originally used for the MC10; Purists should take note
Whatever 3/32 shank rivet McCulloch used at the time really had a small head
Didn't want to mislead anyone thinking they must use a 1/16" rivet. What was important to me was to get the same look of the MC10's I had in the 60's.
Will be more careful in the future even when only a few MC10's are probably built worldwide per year anyways

I appreciate all your efforts in providing your nice pictures and information; really helpful. My son an I use your MC8 rebuild article all the time for reference and inspiration.

John, I have 5 NOS Mc-10s and have cut 4 of the shrouds for header clearance thru the middle of the tag. The rivets McCulloch used on those particular Mc-10s are 1/16". http://www.hansonrivet.com
I'll probably see you at Riverside, Tom

[Scott Kneisel]

I guess 1/16" it is!!
Tom always knows Mc10's best.

Maybe someone drilled mine out. Like I said before, I could really care anyway. Sorry I started this thread.
I'm out..................................
