Well maybe motivation instead of inspiration is more accurate. I took a could days of much need vacation and I spent today tinkering in the shop all day and reading LJ. I got to Neil’s blog, NBeener, and re-read his stove-pipe mod for his HF DC. It motivated me to start sealing some of my leaks. I said some!

I sealed all around the dust collector using foil tape after wiping it down with a rag and mineral spirits.

The secrete is to use small pieces and just do small areas at a time. I used pieces about 7-9” long. If you, read as ME, cut too long of pieces of that foil tape, it gets a bit unruly and hard to work with.

I also started sealing around the blast gates. Those plastic blast gates leak like a sieve! There’s on so much that I can do with them but ever little bit helps.

I did seal a couple of the PVC joints too with the foil tape but the PVC joints should be good. I put them together with silicone caulking. You can see where it squeezed out in the picture above.

Thanks Neil for the inspiration!

I need to get after sealing up the impeller housing on my HF DC… It leaks where the halves are joined… Not so much at the output side of it…

Great blog Chunky! My own DC is in serious need of an overhaul and this blog may be a lot of help.

Do the HF units really leak that much air from the housing?

I don’t think so but an once of prevention… Mine is definitely leaking some where. The collector is not that easy to get out of the hole it’s in so I just sealed every joint while I had it out. I even found a hole in the 5” hose where a brad nail was sticking through it. lol

It starts with thanks for the inspiration.

But … very soon … it’s more like “Beener What have you got me hooked on ?” ;-)

My gut tells me the stovepipe mod made the biggest bang-for-the-buck difference (other than the change to the Wynn 35 filter, that is).

HokieMojo: My guess is … no—not much. But a roll of the foil metallic duct tape is about $9 … and would do about 30 of these, so … it’s virtually zero cost, and may provide some benefit.

I think it IS just a good practice to minimize leakage wherever you can.
