ohhh fr8s with a bonus wood refinishing project, nice
Craigory I feel your pain...countless hours of my life I'll never get back trying to hit various things and fiddling around with a few Jungle carbines. I liked everything about those rifles but they just weren't accurate enough for me and I had to finally set my sentimentality aside and move on.
I applaud your resolve to get that FR8 up and running and your work so far looks great but if it wears you down and you are looking for a rifle that is the modern version of the FR8 or Jungle carbine the Ruger Scout is the easy button. Accurate, stainless, great irons and 10 rd magazines. If wood strikes your fancy grab a laminate one.
If your impartial to wood or synthetic and not married to a claw extractor you could grab an American Ranch and equip irons for half the price of the Scout.
Looking good, but if you are going to refinish it, I'd polish out the Dremel marks with some 200 grit before it gets sandblasted. Polish around the circumference, not along the length of the barrel.
Good call, should be pretty easy to do with thin strips of emery cloth or plumbers abrasive using the typical plumbers technique for prepping copper pipe.
I'd be tempted to start with 100 and move towards 200 as needed.
I did do this with the thin strips of 200gr emerey cloth, what I had on hand anyways, I put the barrel in a vise and went back and fourth with the strips until they were worn out, the Dremel marks are still quite prevalent, if I wanted to make them disappear more it would require removing alot of material.
