    Sorry, I’m late getting back to this thread. Didn’t even notice that new posts were up.

    Things I’m thinking about redoing…

    I used 1/8 inch plywood for the base. I’d switch that to 1/4 inch for the stiffness.

    I’m going to a big gulp style flange/port in the bottom when I switch to 1/4 inch plywood

    Switching to a high density foam strip or door insulation foam to seal the bottom

    I used a Bosch ZCI and put a piece of Fastcap zero clearance insert tape over it to stiffen the plastic plate. Since I live relatively close to Fastcap and the US border, I asked Paul if he would be able to sell me a piece that was wider that the tape used on mitre saws. I was able to get a 4 inch wide piece. SO far it works pretty well in stiffening up the plate.

    I’m pretty happy with the Sawstache pieces. I wonder if I should have taped on the inside of the saw purely for aesthetics.

    I’m going to try Reflector’s mods to the area around the blade to improve the movement of dust out of the rear port.

    Sorry I haven’t been updating that topic for a while. I haven’t had time to make some improvements lately.

    Just start with the shroud between the tabletop and the motor support/sawblade cover. I found that nothing really drops out from below anymore except for that little area in the front where there’s a gap.

    Also seal it from the outside of the plastic shroud, I need to change that when I have time to since it works well right now and I don’t find myself tilting the blade.

    The free hanging strip on the left side where the motor is also helps a lot, that was a big improvement.

    Once you get that done you’ll be dealing with overhead collection more than anything else.

    @Reflector

    What material did you find work the best for around the shroud. Anything that you are thinking about trying?

    @Kamster
    In the video I used shelf liner, I found they were listed online as this:
    Con-Tact Brand Industrial Solid Grip Non-Adhesive Non-Slip Shelf and Drawer Liner, 18-Inches by 4-Feet, Dimples Black
    Con-Tact Premium Ribbed Shelf Liner, 18″ x 15′ Roll, Clear

    But you can find those at Target or Home Depot (Maybe, they might not have the black shelf liner)

    Optionally you might want to try what I did with the clear door sweeps on the bottom of the motor housing:
    http://bethepro.com/forums/topic/4100-dust-control-modifications/#post-424466

    And if you want to go all out on the motor side (It helps with the suction since most of it is lost at that large gap) then cover the inside up where the rods are exposed with the clear door sweeps. They’re visible at the start of the video in that topic.

    What I want to do is to move all the shelf liner material I taped on the inside of the plastic shroud to the outside of the shroud. That way it would wrap around and deform easier when the blade is tilted (I don’t tilt the blade that much as I said before) so it won’t end up compressing and getting cut by the blade. That way I can achieve a 100% seal against the underside of the table and the housing. No need for the door sweeps in the front or any in the back. All the dust would go to the chute and nothing ends up below the table.

    But as of right now, if I’m not making very hard cuts the little gap at the front doesn’t leak too much saw dust. Most of the sawdust on the 4100 is generated above the material and ends up landing all over it. That’s part of the next thing I’d like to do: An overhead 4100 dust collector/blade guard. Some of the designs out there use the airflow coming off the sawblade to assist the process.

    The other, more experimental thing I want to try out but I don’t recommend anyone doing is to channel the air up higher in the sawblade housing. With the sawblade fully down, there’s about a fairly large gap (~2″?). What I was considering was to split the inside of the housing (Using flexible material inside) so some of the suction is directed up towards the front of the housing and the other part of the airflow is where the port still is.

    The problem with the 4100’s design is a lot of air pulled from the rear where the riving knife is and it isn’t pulling air near the front of the sawblade. After getting a Mafell MT55cc I looked inside to find that Mafell did a really amazing job in directing airflow right to the front of the sawblade where it exits the material. I had previously found that sticking the shopvac onto the 4100 means most of the airflow is sucked down right at the riving knife area and there’s barely any airflow towards where the sawdust is coming down. That interior splitter should help pull a little suction towards the front and assist in sawdust collection. Even without a vacuum I theorize it should help since the movement from the sawblade is sufficient to remove significant amounts of dust.

    I don’t recommend anyone to do this one since I haven’t done it yet and it’s a bit risky since it involves making modifications right inside the housing where the sawblade is.

    Shelf liner cut into strips:

    But if you enclose the shroud and the table, you won’t even have to deal with that. I found that enclosing the shroud to the table means there’s effectively very little/no sawdust escaping beneath the table and spewing out the front or rear.

    Any idea how effective these are?

    Looking to do these modifications to my bosch this evening. Came across this video today for overhead dust collection. Gonna give it a shot and see how it works. Little leary of having a bolt directly over the blade. Thoughts?

    maybe instead of a bolt, clamp with some super glue or some other adhesive and let dry then there wouldn’t be a bolt directly above the saw blade.

    Have a look at Dan’s (woodman_412) design for overhead dust collection on a table saw. I think that its a better/safer design especially if you are able to mount the arm to your table saw

    I’m sorry for the late question to this topic. I’ve got a Bosch 4000 and I’ve really liked the saw but man the dust stinks out of it. If like the overhead blade guard that attaches to the riving knife. Like the one pictured earlier in this article. But the power tool spares people are so useless. They aren’t any help. I can’t call them either because I’m in the states and don’t have international calling. Please confirm with me that the vac port guard will work on my 4000 saw. Also what riving knife will attach to my saw. Or just splitter. I don’t have it. I bought my saw used. Thanks.

    Welcome to BTP!

    The 4000 is a great saw, but does not have a riving knife, which also means you have nowhere to clip the dust collection blade guard.

    If you want an aftermaket, your choices are the Microjig MJ splitter or something more elaborate like the shark guard

    I will endorse the MJ splitter. I have one on my old Unisaw mounted in a shop built ZCI. I went with the MJ after a near miss with a kickback. I love it! For dados and other non-through cuts I just swap the ZCI with the splitter for one without. Easy!

    Sorry, doesn’t help with your DC issue.

    BE the change you want to see.

    I hate to say it but that blade is in backwards!

    I got my cover. I kinda fits but I think I am going to modify my riving knife. The dust collection is great on the two boards I cut.

    I have the same – Im just pinching the riving knife. How did you mount yours?

    It creates less dust that way,,,
