So i decided to finally build my Thien Dust Collector. I have to say this thing work un-believable….. The only picture i’m missing is with the reveal cut out of the lower baffle. Lets just say i took the bottom baffle, measure the circumfrance, divided by 3 and i started right at the mouth of the inlet pipe and measure 1/3 around, then next 2/3 (which returns you back to the opening of the inlet) were cut back 1.25”. I took the shop vac apart and cleaned it since it’s about 8 years old and never been cleaned. I put a new filter in it and it SUCKS!!! i will begin to crush the steel garbage can if you block to much of the suction. I vac’d up a ton of sawdust from plywood, mdf, hardboard, and then opened the shopvac, and the filter was still pure white. PERFECT…. How did i live w/o one of these before…...

I have had the plans to make one of these seperators for almost a year now and i still havent gotten off my ass and made one yet. Yours looks like it turned out great, i dig the viewing hole through the side of the can .. slick idea.

I have one of the trashcan cyclone lids and, while it works ok, it suffers from poor design. The Thien Cyclone is so much better. I have one on my to do list. Great work!

I have a “viewing port” on mine too. It’s the bag on the DC. When I get chips in the bag, it’s time to dump the barrel. I’m curious as to how well the widow works for you. My thoughts would be that dust would stick to it because of the static electricity rendering it useless. Also, my chips tend to pile up all on one side. so it may look have empty yet still be passing chips on through the DC fan. I would love one on mine if they work.

@ChunkyC: so far testing it i haven’t had anything stick to it, time will tell more i guess.

@AaronK: The lid is just sitting on the can with a snug fit. I debated some sort of weather stripping but decided against the when it fit so snug. And with the can wanting to collapse so easily i think i have a nice airtight seal…..

@Paul Pomerleau – Would love to have the plans to your circle cutting jig. I have yet to make one and your’s seems to be just the ticket. Maybe another Video on how to build it. Thanks

@John_G. – Very nice and when it starts to collapse the can you know your seal is good.

I’ve made a couple of the Thein Collectors; a small one with a 5 gallon bucket for my shopvac and a 55 gallon drum version for my shop dust collector. They work great. Your filter doesn’t need to be cleaned very often when you have one of these.

This will be my next project. the only thing i am considering differently is to use my elec leaf blower vac instead of my 12 gallon shop vac. the reason being that it has twice the cfm per minute and there looks to be minimal dust in the vac bags. maybe ill have a duel set up and post my results. great work.

Have your say...
