Popular Post derekcohen Posted December 29, 2018 Popular Post Report Share Posted December 29, 2018 I have struggled with dust collection to my bandsaw, a Hammer N4400. The outlet is a 120mm (close to 5") port that is linked by 5" hose 2 hp dust collector via a Super Dust Deputy cyclone. The DC is the next planned upgrade, but it does a decent job of sucking dust (but more power and suction would not go amiss).The dust port ...My plan was to add a hose near the source of the bandsaw dust, that is, where the cutting takes place at the blade. Not sure how to attach the hose, I did a little research ... and came across a video on YouTube by Rob Cosman. I am not sure if the idea is his, or whether he borrowed it (I did come across another that was made several years ago). Suction in this case would be via a Festool CT26E.The idea is very simple. This is the construction of the dust collector ...Just a bit of 2" PVC tubing, with an end cap (I planned to lock the end to the bandsaw with a spacer, but this was unnecessary). The tube is sawn half way for the blade (in this case, a 1" Lennox) and opened up a the top (for sawdust). Behind the dust collector is the holder. The holder is attached on the Hammer here (red arrows) ...This is half the holder attached (with bolts) ..This is the other half of the holder, with recesses for the bolt heads. Obviously, the pieces are screwed together.This the collector attached ...So, the question is does it work?The inside of the bandsaw is usually coated with dust and quite thick on the floor. This picture was taken after a clean and then sawing about 20 feet of MDF with just the lower dust port in use ...I found that the lower dust port needed to be connected for the system to work optimally. It was not enough to just use the upper collector. However, with both connected, after repeated use through the course of an afternoon, this is the inside of the bandsaw ...The connection from the CT26E may be may with either the 28mm hose ..... or a 50mm hose ...Both worked equally well, but in the end I decided to use the 50mm hose, as it was possible to swap it over to the K3 slider as well (where it has reduced dust spray considerably) ...Hope this helps others.Regards from PerthDerek 5 1 Quote Link to comment Share on other sites More sharing options...
Bombarde16 Posted December 29, 2018 Report Share Posted December 29, 2018 This helps quite a bit, thanks. I've got the same struggle with my little Porter Cable, so I'll have to give this a try. Quote Link to comment Share on other sites More sharing options...
Tom King Posted December 29, 2018 Report Share Posted December 29, 2018 I like it. Just like sharpening, where sharper solves all sorts of problems, moving more air solves all sorts of DC problems. I wonder if a hole in the PVC cap, or even the whole end open, would help by allowing more air flow across the blade. Quote Link to comment Share on other sites More sharing options...
drzaius Posted December 29, 2018 Report Share Posted December 29, 2018 I too saw that video & plan to do the same on mine. I like the holder for the pipe & if fitted with wingnuts would make remove quick & easy. Quote Link to comment Share on other sites More sharing options...
wdwerker Posted December 29, 2018 Report Share Posted December 29, 2018 This looks like a great idea . I will have to see if I can make it work on my old Delta bandsaw. Quote Link to comment Share on other sites More sharing options...
derekcohen Posted January 1, 2019 Author Report Share Posted January 1, 2019 I did not want to live with a double vacuum system, so connected the main 5" hose to the collector at the blade. My concern was that the 2 hp DC might not be powerful enough to pull dust through two hoses ...This is a 2 1/2" hose ...With all dust collection switched off, this is the result after sawing 1500mm of MDF ...Now I tried a few variations after this: removing the end cap for increased air flow/ventilation (the cap on was slightly better), and taping up the blade kerfs in the tube (this was slightly better). Essentially, these all resulted in this ...Bottom line: I think that the little dust in the corner is a dead spot for cleaning. The system is working so much better than ever before, and now it only needs one switch at the DC to get it going.Regards from PerthDerek Quote Link to comment Share on other sites More sharing options...
Chestnut Posted January 1, 2019 Report Share Posted January 1, 2019 Is there a way you could remove the air seal from the bottom edge of the door? It looks like there isn't enough air flow in the lower part of the saw to clear the dust out. The fully sealed lower cases of band saws aren't the best for air flow. My saw has a gap along the whole bottom of the door and the floor inside is spotless. Just an idea. Quote Link to comment Share on other sites More sharing options...
treeslayer Posted January 1, 2019 Report Share Posted January 1, 2019 Consider this idea stolen Derek, it’s amazing how much sawdust a bandsaw generates, I see all kinds of benefits from your idea. Quote Link to comment Share on other sites More sharing options...
