ASA Dimension

[m600]

Hi

Trying to make an ASA on my lathe and im looking for the dimensions past the thread, I.E the surface which the oring on the air bottle seals against . I think its around 17.8mm? but the oring is 18mm so i dont want to make it too large

Any help appreciated

Many thanks

I was just going to ask the same thing last week. I found this page and maybe it can help you out if you have access to 3D cad:

Unfortunately, link is dead. I have one on my drive if anyone has questions about dimensions.

So I actually went through and measure every ASA I had on hand not too long ago and they ranged from .69-.705.. I had a couple outliers that were close to .72… but those were a mix of anodized multiple times and reeeeeeeeaaally old.. so I didn’t include them. In everything I’ve machined I aim for .695 and haven’t had a problem yet
