I just got another makers stamp. I have been wanting an oval stamp for times when my other one doesn't fit or look right. My other one is a steel stamp made by Infinity Stamps. I wanted to see how the Grey Ghost Delrin stamps are. The order went smoothly and after I sent my artwork to Jeff, he had the stamp to me in a couple days. Great service, there. It took longer to get the steel stamp but there's more involved in making it.
This one was inspired by a Main & Winchester stamp.
Here's how it compares to my steel stamp.
The Delrin stamp is laser cut so the whole thing is straight cut where the steel stamp has tapered lines. The impression is ever so slightly crisper with the Delrin one but not greatly so. The image made with the steel one is slightly softer and maybe a bit more historically correct looking, but not by a lot.
What is the most different about them is that the laser cut image requires a heck of a lot more oomph to get a decent impression. My 32 oz UHMW mallet wasn't up to the task. I tried several times with it but finally found that I got a good impression from two whacks with a 1lb dead blow hammer (which is now one of my leather tools). On the plus side, lining up the stamp for the second blow was easy. I think it would work better with an arbor press or maybe in my drill press.
So which do I like better? I like my Infinity stamp a little better but the Grey Ghost stamp was considerably more affordable. Both are top quality. The steel stamp will last forever where the Delrin one may not. You wouldn't want to toss the Delrin one in a drawer with other tools. When the time comes to get another stamp, it'll depend on my mood which one I get but steel will probably win out.
