Washerless pinning questions

I love the clean look of vintage ivory scales with washerless peened pins. A search for washerless peening revealed an interesting post here, by AronX from 2008.
Has anyone any experience with this? Also looked up #6/0 tapered reamer that Aron recommended and,

1. They do not have much taper and
2. Prices range from $7.00 to $60. What’s the difference?

I would think more taper would be better.

In a 2011 post Neil Miller here suggest an ivory washerless pin was hammered by a flat or cross pein hammer, not the Ball side, if I read his post correctly. What is or would the benefit if this be?

And… here is a 2011 post by Skipnord of a beautifully re-scaled washerless pinned C.V.Hejestand, just to demonstrate the elegance of washerless pinning and Skipnord’s craftsmanship.

Stunning.

I really think you need to go re-read those threads, I am not reading the same conclusions as you, or seeing the same results as you are talking about..

The washerless pinning on the Vinatge Ivory scales is no different then the Washerless pinning on every other type of scales I have seen,, Some the best I have every found is on some of the Shumate razors their way of doing it left these beautiful near perfect domed peens that look ,more like they were melted then hammered :) simply awesome

If you want to go washerless with Ivory,after your pin holes are drilled,put a micro chamfer on the edge to distribute the pressor,than anneal the pins before pinning.JMO

Jewelers use small diameter tapered reamers, I've got them from 3,5 mm down to 0,3 mm, they look like needles.
Do you want headless rivets or just without the washer?

Wish I could take credit for the washerless pinning mentioned above, but I did not do that one. I've never tried washerless. From what I've read, it is very easy to crack ivory. This is a tad above my present pay grade. Maybe in the future. Good luck with your project.

Here's an old thread when I was trying to learn. It might be helpfull as well!
