Hey guys, I'm new here. I'm planning on making some mortar racks that fit dr11 HDPE pipe for consumer shells and I'd like to get your guys' input on this. I'll be buying 50 mortars, and I'll make 10 racks. The holes on the sides are for a bolt/wingnut that will attach to some plywood or 2-bys (haven't decided yet) with many holes in them so I can flexibly arrange them in a finale or fan rack style. 2.5" holes will be bored out with a 2.5" DIA hole saw (bi-metal's okay right? and do you suggest getting an arbor?). all the wood here will be treated 2x4.
It seems sturdy enough. What do you suggest for fastener type (screws preferably) and placement?
Any advice would be great.
