grovey Jul 28th, 07, 10:34 PM I watched horsepower tv today and they were using a new crane cam and valve springs that were media blasted with walnut shells. Whats the skinny on these? are they not as new as i think ? Maybe a older show, as i have not watched it for awhile. pdq67 Jul 29th, 07, 2:02 AM I have NO idea why they would walnut shell media blast new parts unless it's just ta do a final de-burr/clean-up??? Sounds like they have way too big a filming budget to do something like this, imho..... pdq67 zdld17 Jul 29th, 07, 9:55 AM This is as PDQ mentioned, deburring for removal of stress risers, but you would think that a company like Crane would have done this in the manufacturing process. Maybe these media shot springs were used? 461RAT Jul 29th, 07, 9:58 AM PDQ,Parts Delivered Quickly.Ever see those little pickup trucks with those letters on the door? zdld17 Jul 29th, 07, 10:05 AM PDQ,Parts Delivered Quickly.Ever see those little pickup trucks with those letters on the door?
