If anyone in the Central Virginia area is interested, I have a baffle I built and used for a while, a couple of years ago that is now disused and just collecting dust (no pun intended) in my shop. It worked great but I decided to make a Franken-collector tophat with my HF DC a couple of years ago. Anyway, I don’t need the lid anymore and I figure trying to sell it is just more trouble than it’s worth, but I would rather give it away than throw it out. I made it with 1/2” MDF, a couple of 4” adapters, weatherstripping, bolts, and garden pipe for covering the bolts. It’s not the prettiest thing in the world but it works well. It’s sized to fit on a 30 gallon steel Behren’s trashcan. Attached is a picture of the lid. Also, I made a Sketchup model of my take on the tophat design that is up on the Sketchup warehouse. You can find it by searching for “Meglathery” in the warehouse. I based it off of a 6” hose inlet design. I may post a photo of that in another post.
PM me if you are interested.
