Chipping question

Jerry Berg · Post by **Jerry Berg** » Mon Nov 24, 2008 8:08 pm

It takes me about a 3 hour or so round trip to pick up some 100 grit or above aluminum oxide blast media, haven't been able to find anyone closer. My question is will 70 grit work out allright? I found a place about 15 minutes from me that carries the 70 grit. If I use the 70 grit is there something I should know, and why would it not be recomended if it is indeed not recomended. I'm trying to save myself a long drive if I can.

Thanks, Jerry

I was mainly worried about the rougher grit eating away the vinyl stencil. Could I use less psi and be very careful and still get an etch without eating the stencil? I guess I'll find out because I just picked up the 70 grit!

I have used 30 grit with low pressure but have the best luck at that point using sandblast stencil. With 70, I can use vinyl.

Hey Jerry,
This is off topic a bit, but why not just have 100 grit shipped to you? If it cost you $50 for shipping, it would still be worth the expense vs gas and time for 3 hours of driving.

I used to blow a good part of a day driving from Moore to downtown Oklahoma City each week to buy a couple of quarts of lettering enamel and some tape. After moving to JH back in 1986, we had to ship almost everything to us. We had to pay shipping expenses, but they were much cheaper than our shop time and gas.

Mike,

Having it shipped was my first consideration. I got to thinking just how much it would cost for packaging and shipping on a 100 lb shipment. I thought that I could make do with the 70 grit for now untill I have the extra time to drive. I've got a few days off here for the holiday and really wanted to get on some chipping. I usually do stock up on things when I purchase materials, saves $ all the way around. Also, I'm really trying to watch every cent I spend at this time. I've got a number of birthdays to buy gifts for this winter and Christmas, and who knows what's going to become of this economy. (now that's really off topic!)

Thanks, Jerry
