The bit and bulkheads will arrive tomorrow I have come up with a soultion to the wier comb I can go use club workshop if i bring my own tooling the are trying to phase out plastic use with their tools but I am still able to use the equipment so I figured I may as well make a custom sump where is a good source for plastic also I assume I should use 1/4 for the box is this right? was planning on 1/2 for the sump
