I’ve loved my little Bosch 4100 table saw but have always found the dust collection lacking. A while back i found an article on fine woodworking regarding closing up these little jobsite saws to catch the dust. I set out over the weekend to upgrade the dust collection and this is what I came up with.
1. I added a zero clearance insert and sprayed some slow expanding foam under the table where there were cracks between the table and the base. I did this on the front and back edge but let the edge by the motor stay free so when the dust collector was on it would try to pull air mainly from the motor side of the housing. I did this for two reasons
Next i cut out some covers for the front and back face of the base assembly and stuck them on the saw with velcro so when i wanted to cut at a 45 degree angle i could simply take them off. This velcro didn’t stick well and I’ll be using some magnets next.
I then added a piece of 1/4” ply between the gravity rise stand and the base of the saw to close off the bottom. At the same time i noticed that the most effective place a dust collection fitting would attach to the base was in a area that had me turning the saw around on the base. I mounted the dust collection fitting to the 1/4” ply with 1/4” bolts(overkill but it is what i had on hand). Don’t forget to cut out the hole under the fitting either.
Lastly i attached a section of 2.5 flex hose to a 4” x 2.5” wye fitting and attached a 4” main trunk to the under cabinet side of the the base.
Hooked all up to the dust collector this badboy stays clean as a whistle. It’s a vast vast VAST improvement and I can still fold the saw down too!!
Hope the pictures help to explain my ramblings.
