Need a blasting cabinet

Have a HF cabinet. Modifications I made are. Added another stove bolt between every one on stock cabinet, new gloves ( originals are junk), different lighting ( was going to use original as trouble light, it burned out instantly) , plumbed air to add a blow gun inside cabinet, added smaller spaced screen on bottom , added a baffle over outlet. The gun and siphon tube system needs help, (haven't quit figured that out yet but the more I use my media the better it works , suggesting that finer is better.
