[QUOTE="specweldtom, post: 444331, member: 2580"] Welcome to the site. It is a good one. If the Sako 85 has inch pattern barrel threads, it will be an easy rebarrel. If they are metric, many 'smiths won't take the job. Metric threads can be cut on inch pattern lathes that have spud gear setups for them, but my understanding is that once you start the thread, you can't disengage the carriage until the thread is finished. It would seem to be very tricky stopping/starting the lathe and backing the crossfeed out and feeding it in for each pass. I wouldn't even try it going toward a shoulder. I guess you could invert the tool and feed out from the shoulder with the lathe in reverse. That would cut a right hand thread without risking chewing up the shoulder and breaking the tool. Maybe someone will jump in who knows what barrel thread the 85 has, and if I have described the metric thread problem right. Good luck, Tom [/QUOTE]
