Re: D9R and 463 pull scraper

Joe, awesome job, as usual. Do you have a reference for sizing the o-ring grooves? O-rings are easy to find, but I'm not sure how much clearance or squish to allow for proper sealing without excessive sliding resistance. Did you solder the large end on to the barrel or turn it from one piece of thick-wall tube? Thanks!

Ken
