Small inexpensive outdoor Blast Bunker for a 3lb BP mill


Recommended Posts

Low teck, inexpensive, small & very effective.

You can find irreparable steel belted tires for free.

Tire shops will give them to you free, as they have to pay to have them hauled away.

 

Acquire 4 or 5 used tires.

Drill holes in the tires & bolt them together tight side to side (nuts, bolts & large washers).

Bolt pattern is triangle shaped 3 per tire to tire.

 

Dig a small trench about 10 inches to 1 ft deep the combined length of the tires.

Roll bolted togather tires in trench.

Fill bottom of tires with sand or concrete to make a level floor.

(think dry sackcrete & hose in enough water to wet it & let it set up a few days)

 

If you use a sand floor, place a piece of thin plywood or board inside the tires for a flat floor.

To close > stack sand bags on both ends.

 

Cover tires with sand bags side to side.

Remove a few sandbags from 1 end for entry/exit.

 

Place mill inside on flat floor (use extension cord to power mill).

Replace sand bags, plug in extension cord.

To waterproof it, place a tarp or pond liner under the sand bags.

 

Sort of like a blasting mat.

Google "blasting mat" if you have never seen them
