Is My D C Too Small?8/12/16
I have an older Jet 2Hp 1Ph collector, bag on top and bottom, with 8' of 4" flex hose.
I'm getting chip dent running soft wr cedar thru my 15" planer. Is this collector too small, or is the flex hose the problem?
I have a 15" Jet planer that leaves chipbeat marks on anything I put through it unless I take off .015". Doesn't matter what I put on it for DC.
8' shouldn't be that bad, wouldn't go any more. Get a shorter pc and try it out.
Chip beat is a common problem. While not always the cause, good dust collection/chip removal solves it for most shops. Top filter bag collectors are also known for variable cfm, depending on dust on the filter bag, air tightness and type of hose. The corrugated hose can really suck the cfm's out of a collector.
Assuming your planer is in good operating condition (tight exhaust hood, proper knife projections, baffles in place), the next thing is dust collection.
I once replaced a top filter bag collector with a full shop system once I did the calculations on time spent with the hobby type Powermatic collector. I dealt with dust - and got a good dose of fine dust - several times a day when changing bags, hauling bags, dumping bags, etc.
After the Oneida system was up and running, I dealt with shavings once a month or every 6 weeks, dramatically decreasing my exposure.
In labor savings alone, the then 3k system paid for itself in 9 months. That was 26 years ago, and it still runs perfectly. It is cleaner, quieter, and more effective than any starter system.
I suspect it's the flex hose, does anyone make a flex hose that''s smooth on the inside?
Just use rigid duct. Knock the cake out of the top bag. Start saving for a real dust collector system that filters out the fine dust that really does the damage to our lungs!
Oh I have great airflow out the shop and no neighbors to coat with dust, trouble with rigid duct is I move the planer around, but then I move the DC too, I'll look into rigid!
would anyone have any Info or photos of a rigid duct setup for a mobile planer and DC like mine? I only use it on this one 15" planer.
So this is how I have it set up now. How would I run rigid ducting to the planer, maybe using a short run of flex hose at the planer end? What type of fittings would I use?
here I'm planing 20' long pieces, running shorter lengths I usually have the planer close to the DC.
I'd sure like to see similar setups as mine :-)
Hey Leo, good advice about only taking of .015, that helps a lot with the chip beat, thanks for that!
Only problem is it usually makes you take 3 passes. I'm old school so 90% of my work passes over the jointer. I face, then I plane.
So I'll set the planer for .030 over the final thickness. Usually get a good amount of chipbeat on that pass. Then lower it .015 and do the 2nd pass and then .015 to the final pass and now you have both sides looking good.
Wouldn't be a problem if I had a widebelt.....
That's about half the dust collector you really need. Get a cyclone style machine with a real filter on it. That little dust collector lets the fine dust through the bag, into the air, then into your lungs and blood stream. About all that thing does is limit the amount of sweeping you have to do.
So what would be a good cyclone collector, and what size are you thinking?
I don't worry too much about fine dust as I have real good airflow out the back door especially with the fans going.
