shot blaster question

The smallest width I been able to find is 8"-9" wide. Has anyone had any experience using one and cutting down the width? I am to do a job on a military base that calls for 3" wide zone marking. 50% is on untreated concrete surface on the exterior of different bldgs. The other 50% is on the the interior warehouse/hangars concrete floors. Quite a few are treated with Epoxy paint and/or sealed. I want to get the pattern as minimal as possible in case they (powers that be) require me to re-coat the affected areas that remain exposed after painting the 3" striping.

Tape it off with duct tape.

To protect what you don't want blasted.

I run a reducer on our Blastpro 10/27, it works well. This is a ride on machine that has alot of power though, I am not sure about the smaller electric units. You may want to look at the B&W SB6, it has a 6" pattern that is more like a 4"effective width that fades to 6". call me if you need some ideas. [phone removed] - Jonathon

We have 2 of the BW SBC 1200 ride on units that have 12" blast heads. BW Manufacturing makes a "line stripe adapter" for them that adjusts the blast to a 4" pattern. Be prepared to spend a lot of money though. Those units are not cheap.
