First I sanded down all the pieces, then melted white legos with acetone and painted it on, so that the sides would be smooth and uniformed.
I like this a lot! Nice call on adding real screws, hot glue and supporting the barrel with a rod
Can you clarify....from what I gathered.... acetone chemically dissolved a lego brick and you lightly painted some on the outside for a smooth finish? or am I completely off base? hahaha
