Keith, many thanks for yours!
I am sorry with my term "not very important"... I didn't mean that a stopper is not important in a front rest, I use the stop most of the time myself, too. My 'thought' is just, I have provided a stop assembly that can be folded 90% & tilted up & down by a bit (in effort to suit various stock designs), easy & quick to adjust (even without tool), and option of rubber O-rings or smooth delrin.... This is probably one single item that has most changes in my rests!
Re; the height of the stop, some people ask it's to be taller (done), some others need it's to be shorter (done too, but then I make it in 'medium' tall).....some need the leverage to be longer (done), some say it's too long...some prefer the O-rings, some prefer the smooth delrin...and on....
My 'thought' is, people can easily change or modify the height of the stop by him/herself. For instance like what Richard did to his. Put a spacer (or a series of spacers), and voila! It's still pretty & work fine/functional, too.
The "heart" of my front rest is the head/coaxial unit.
The "soul" of my front rest is the smoothness & workmanship.
Richard, good job there! Many thanks for posting the photos! I like it.
Wilbur, many thanks for yours!
You're right, I would add spacer(s) and/or different stop design, soon.
