Rockytime Posted June 28, 2020 Report Share Posted June 28, 2020 Perhaps this only happens to me, but...I'm cutting 1/2" Cedar with #1 PMG blade. As I'm cutting fine sawdust piles up both behind the blade as well as in front of the blade which obscures the line I'm cutting. My dust collection is adequate. While it does not pick up the sawdust when the cut is completed it often sucks up the piece that was cut out. The DC orifice is 1/2" tubing. I've tried a Lock-Line nozzle which does not work as well I'm assuming it is static holding the sawdust in place. I tried wiping the pattern down with fabric anti-static sheets. Dumb, but it did not help. I just finished cutting 1/2" Oak with #3 PMG blade. No problem. So...just wondering, could it be the Cedar and small blade causing the condition. I don't call it a problem. When it occurs I just lift my foot off the foot switch, brush off the dust with an acid brush and continue. I would not post something so trite or weird but things are awfully slow in the Village this summer. amazingkevin, OzarkSawdust and OCtoolguy 1 2 Quote Link to comment Share on other sites More sharing options...
OCtoolguy Posted June 28, 2020 Report Share Posted June 28, 2020 Doesn't your blower work? It should keep that dust from piling up. Rockytime 1 Quote Link to comment Share on other sites More sharing options...
kmmcrafts Posted June 28, 2020 Report Share Posted June 28, 2020 I quit cutting cedar shortly after starting.. there was two reasons.. and this was one of them.. The other reason was it was quite fragile.. not much strength to it after cutting out all the inside cuts.. I made ornaments with it thinking they'd be pretty out of the reddish color plus many people like the smell of it.. But for me they broke very easily.. the sawdust around the blade as you are experiencing.. also to me the smell was quite strong and irritating.. But I'll admit I cut it back when I was first learning scroll work back in 2005 ish.. never cut it again, LOL amazingkevin, Rockytime and OCtoolguy 2 1 Quote Link to comment Share on other sites More sharing options...
Rockytime Posted June 28, 2020 Author Report Share Posted June 28, 2020 I agree Kevin. However, keeping in mind how fragile it is I love it for certain projects and it cuts beautifully. Smells good too. kmmcrafts, OCtoolguy and John B 3 Quote Link to comment Share on other sites More sharing options...
kmmcrafts Posted June 28, 2020 Report Share Posted June 28, 2020 It cuts easy.. just the sawdust is like sticky or something.. maybe sap from the tree? Not sure.. it does smell good to cut for a short while.. but after cutting several hours it gets a bit strong for me anyway..

I don't use blowers on my saws. I want to get rid of the dust and not spread it. The dust from very tiny blades is nasty.

kmmcrafts Posted June 28, 2020 Report Share Posted June 28, 2020 I think this might work to move that sawdust.. You would need a hard hat and epoxy glue the hose onto the hat so when you look down it blows the dust off the line.. https://www.amazon.com/Husqvarna-570BTS-powerful-X-Torq-Backpack/dp/B008JL05I4?ref_=fsclp_pl_dp_12 nickp, stoney, poupster2 and 4 others 1 6 Quote Link to comment Share on other sites More sharing options...

OzarkSawdust Posted June 30, 2020 Report Share Posted June 30, 2020 I get that also Les, but a much smaller pile...with a blower on my King. But I get it with different woods, and not all the time. I can even be cutting a line and get it for a couple of inches then turn a corner and it's gone. I just figured it had something to do with the piece of wood, maybe the clear shelf paper/pattern printed on a label, or humid/dry air in the shop. In other words...I have no idea!!! amazingkevin, OCtoolguy and Rockytime 2 1 Quote Link to comment Share on other sites More sharing options...
Rolf Posted June 30, 2020 Report Share Posted June 30, 2020 What is your top layer? Paper or do you have packing tape on top of the pattern? OCtoolguy and Rockytime 2 Quote Link to comment Share on other sites More sharing options...
kmmcrafts Posted June 30, 2020 Report Share Posted June 30, 2020 That's a good question from Rolf.. because I really get this when I put packing tape on top of the pattern.. however it isn't piled on the top, it gets piled between the tape and the pattern.. why I do not cover my patterns with anything unless it's a necessity..

No backer, BB covered with Duck brand shelf paper, pattern sprayed with 3M 77, pattern attached to shelf liner a d burnished for good adhesion. No packing tape. The wood is Cedar but it occasionally happens on other woods. I'm thinking it happens when I use very fine blades and the sawdust can't escape easily.

dgman Posted June 30, 2020 Report Share Posted June 30, 2020 Les, most cedar is not kiln dried. It also contains a lot of oil. So you get a moist, oily powder rather than dry dust. It’s probably not dry enough for your dust collection to pick up. Like trackman above, I have my blower pointed at my dust collection port. I don’t have a remedy for you, just wanted you to know what your problem was. poupster2, DJ2772, OCtoolguy and 2 others 3 2 Quote Link to comment Share on other sites More sharing options...

DJ2772 Posted July 1, 2020 Report Share Posted July 1, 2020 Interesting stuff here about Cedar. I just watched a video about how Cedar is a unique wood as dgman said in his post. What happened to you reminds me of the time I experimented with a design that I put clear packing tape over...thought it would help cool the blade, yeah just got dust stuck underneath and made it next to impossible to see the line haha.

I always apply clear packing tape on top of the pattern. The trick is to burnish the tape down with a block of wood so the tape is perfectly adhered to the pattern. If you do this, dust can’t get under the tape. kmmcrafts, Jim McDonald, John B and 2 others 4 1 Quote Link to comment Share on other sites More sharing options...
Norm Fengstad Posted July 2, 2020 Report Share Posted July 2, 2020 Thanks for the discussion.Cedar does look , cuts nice and has an appealing aroma. For me it also gives me water blisters mostly on my face. An Occupational Hygienist told me years ago I had a sensitivity to the oils in the wood. These oils are not good for the lungs, enter your system through the eyes and sometimes through the skin.

OCtoolguy Posted July 2, 2020 Report Share Posted July 2, 2020 Les, you mentioned that you didn't want to "blow" the dust around. When you are going to be cutting cedar, why not put a box fan next to your saw with a furnace filter attached and blowing away from the saw. Then you can aim your blower right at the point of cut and the dust will be picked up by the furnace filter. Not 100% but pretty much. I have done this with very cheap filters. In fact I bought a 4 pack for about 4$ at H/D. and bungee'd two on each side of the fan. It's amazing how much they catch. You wouldn't have to do that with anything else, just the cedar. A thought!

Ray, I have a 20" box fan which I used to use. I stopped because while it did collect some dust lots of dust would escape into the air before reaching the filter. Even with the fan close to the saw. I removed the blower hose and replaced it with suction line. If it were possible I could hang Wen dust collector from the ceiling. I physically am unable to do that. Easier to just exhale.

amazingkevin Posted July 7, 2020 Report Share Posted July 7, 2020 i spend more time fixing cedar and don't use it that often. Beautiful wood and my favorite but I'm not looking for extra work. Rockytime and John B 1 1 Quote Link to comment Share on other sites More sharing options...
