So here's my new contraption. It's a 8$ oil pan with a cutout and a 1 1/2 electrical 45 in there. Used it on 4 jobs and really like it better then the mortar pan. You make the conections in the pan. So if you make your own, learn from my mistakes and:
-insert the elbow close to the handle, this way if you pick it up by the handle, nothing drips out.
-use a guide hose only 4 long.
Total cost was under 15$ to make.
