I have determined that my vac hose has been causing disconnects. Ready to pull the plug for an antistatic hose, but want one that works ( vs the sales truth). Looking for under $100 which leaves out Festool. Need one in the 1-1/4 size.
I then switched to urethane flex hose with a steel coil. Here is the 2.5" hose and 4" hose that I use now. I also have 6" hose that I bought, but haven’t used yet. When I do use it, it will be for a longer run out of my shed for my “big stuff” (jointer, planer, table saw. . .), since I don’t have room to run things in my shed, so I have to do the “big stuff” outside when it is not raining. I’ll use the 6" flex hose to go the 15 feet, then reduce to 2.5" to hook up to the planer or jointer or table saw or whatever.
I trimmed off some of the urethane and then ground the coiled wire to prevent static disconnects. My last disconnect was because the ground wire came off.
As a follow up: I bought the Makita 1-14" antistatic hose for about $60. Hooked it up and ran a bare copper ground wire taped to the hose every foot or so. So far seems great. Been able to turn vac on and off while cutting and no disconnect. Thanks for your input
I just modified my set up after a presumed static disconnect. I obtained some 16 gauge strand bare copper wire. I ran the wire inside of the suction hose from the spindle base through the suction hose to the outside of the enclosure and I wrapped it around the outside of the suction hose to the outside of the cabinet. I then ran two separate grounds. One is hooked up to a wire inside of my 4 inch dust collection hose and is grounded on the dust collection motor. The other is run to a common ground inside of the electrical box for the circuit that runs the spindle. So far, I have not had a disconnect.
