Jim,I am looking at your video and the box. Just need to get to the PO.I bought my sand at Northern but up here where their HQ is. You probablywent to the one in Richardson on Arapaho. You need to go to a place calledClemtex, Inc. last known address to me is 4770 Gretna, Dallas TX 75207 214631 0584. They are at the Motor Street exit south off of I35E nearIndustrial Blvd./Irving Blvd. Look in your Mapsco.You get #5 sand, remember by five fingers on your hand! They might bereluctant to sell it to you if you say you are sandblasting so if they ask,say it is for the ashtrays in the office building where you work. It is thesame stuff. It should be 5 or 6 bucks for 50 lbs and get two bags or so.They have all sorts of other stuff. If you are not derusting and descaling,you might consider glass beads for more money.You will also need to get your "gun" there. As a matter of fact, I mighthave you be my go between as I can't find a source up here. I might haveyou pick some up for others on the piet list that need them, prepaid ofcourse.The gun you want is stock number 10107. Gun Ass'y Complete is what it sayson my receipt from 4/2/93. Can't make out the manufacturer but looks likeCIGWK. Price was 54.50 plus tax. I will send a picture later today of itso you can walk in with the picture.You want to get the right gun. It is expensive because it has a CARBIDEventuri but mine has been in good use for 9 years now and shows no wear. Itis imperative you have this gun. No ceramics here. If you use the wronggun, it just won't work right after an hours use. I will measure theorifice size of my gun and send youthat when I send a photo. You do notwant a bigger orifice, same size is ok, but smaller is probably better.Better to retain your pressure and cover a little less ground.As far as the vacuum, you are creating a mammoth sandstorm inside the box.It will be so cloudy after a minute that you won't be able to see your handin front of your face. You are pumping air into the box at 100 PSI and at11-15 Cubic Feet per Minute. All the air has to go somewhere. If no vacuumthen it will blow out through every seam and put dust all over the garageand make a big mess. It will also go into your lungs and you will contractsilicosis and die a horrible slow death. The key is to create a negativepressure inside the box so that the dust is trapped by the filter of thevacuum. Better yet, use an extra lung vacuum hose and put the vacuumoutside as even the filter on the vauum won't trap all the fines.You must use a vacuum.I hope you took pictures that we can share with everybody. I would not mindhaving some to post on the EAA website.chris-----Original Message-----

You could check out your local "Harbor Freight" store -- I remember seeingboxes of sand there by their blast cabinets -- don't remember the price'cause I wasn't looking for more sand -- I get mine from the "Sand Dune"exhibit we have at our museum -- it gets changed periodically after itstarts to look gray from the Alum. fan blades wearing away!! (it's a sealedbox with a fan to provide the "wind" to drift the sand)Mike C.Pretty Prairie, KS----- Original Message -----

You could also try a larger swimming pool dealer. I carry Red Flint Granitesand in my shop.(.45-.55 mm) It is rather aggresive but doesn't dust nearlyas much as white silica sands. It really depends on the nozzel you areusing.Dick----- Original Message -----

I have heard Soda Bicarb beads refered to as "green" sand. I have seen adsfor Soda Blasting in the papers for old car restoration. Yes it isconsiderably less dangerous healthwise but also beware of going to the beachon a windy day. Free silica is present in all sand and taking properprecautions will take the risk We sand blast swimming pools forrepainting. When working indoors we cover the pool with poly and installducting fans for intake and exhaust air and anyone in the work area is inprotective gear with fresh filtered air in helmet.I dont think using a small blasting cabinet poses any real risk as long asyou vacuum as earlier discussed, or let the dust settle before opening.Dick----- Original Message -----
