Chris, I think you are right to go with tumbling rather than sandblasting. If you get aggressive enough with the sandblasting to remove burrs and tool marks you will likely be rounding over some sharper edges you want to remain. The tumbling may do a little of that too depending on the media but it takes longer and you can stop the process at any point. I prefer bead blasting for just adding a nice matte finish to metal and not to remove metal. You may well find that the tumbling is enough on its own.Bill
Quite an improvement in the looks department after tumbling You are on quite a streak here with another great long build - only problem, I'm using way to much because of you
Looking real good Chris! I think the finish looks really good. I like the way you created the center "lug/Grouser" with the ball end mill. It's definitely worth the time spent making good jigs & fixtures. You'll have quite the collection of them when this project is complete. Really nice work! John
Hi ChrisThe tracks sure look good after a trip through the bowl. Are you running them with some soap; and for how long?Dave
Chris, those tracks look great! Although I'm not sure it'll make much difference when they're all mucked up with mud from running around in your backyard! I'd love to see a picture of your tumbling setup if you get a chance.Jim
