Ok I used the JET Holiday sale and bought a DC-1100VX with the cyclone set up. Before this I was using a HD and Fein Turbo 2 with a cyclone set up.

Most of my tools are portable so they do not have 4” ports on them. The biggest reason I bought it was to keep up with my Dewalt Planer. I thought I could retire my above set up and use the Fein hose for my track saw.

I understand that DC works on less pressure but moves more volume correct? For now I am simply using a 4” hose that I was going to move from machine to machine which fine for now.

Problem is new set up just isn’t working as good as the shop vac and cyclone. If I take the 2”?? Fein hose and try and get it stuck to my open palm it just falls off. It doesn’t provide enough suction to work on the track saw or even the miter saw. It will barely clean up the floor.

Any advise? You can see that if I pull the plug off the other 4” port on the DC the bag fill right up and it is getting full air movement. Is using a DC and reducing the hose down to 2.5 or even 1 1/4 for a mitre saw or track saw not feasible?

I thought I ended my dust issues and now have an expensive item that only works well with the planer. Do I have an issue? Is anybody using a DC with these reducers effectively?

Thanks

I have found it okay to reduce from 4” to 3.” Small than that I think becomes problematic.

I would say that no one is getting vac type performance from a DC with a small hose. The tools are made for different circumstances. The vac overcomes high static pressure (resistance to air flow) to mover small volumes of air. The DC is the opposite. so hooking a DC to a small hose introduces so much drag (SP) that it can’t move the air it is designed to move. You did the right thing buying one, both are needed in a shop (IMHO).

It was an impulse buy and they never work out for me. Got the 20% off and free shipping to my garage. I would have upgraded the TS if I had thought it out. This woodworking is expensive.

I am still not sure if I have an issue as hooked straight to my planer I get a lot of debri all over the machine I did not get before. If I pull the 2nd plug it will suck everything right out. I am assuming it is creating a vacuum with the additional air flow?

I am going to check it out today. Anywhere I should look for low vac pressure besides clogged hose? It is only a 10’ run straight to the machine with clear hose.

Thanks and I appreciate the info.

I’m not following exactly how you’re set up. If the DC is hooked to the planer with 4” hose it should be getting 99% of the chips. No need to leave that second port open, you want all the air flow into the DC coming from/through the planer…same with any other tools you hook it to. When you say you have a cyclone setup, is that a trash lid? if true, you can’t have any leakage there….the lid needs to be completely sealed to the can.

Part of issue found. There was a 2×2 square caught in port I was having issue with. That is why when I opened other port bag would fill as it was getting full flow. Planer now works better.

I was at Rockler and started talking with someone buying hose and he had a good idea.

I was coming out of DC and reducing down to a 2 1/2, 2 1/2 hose to the TS. He told me the 4” to 2 1/2 adapter was killing my airflow. I then went to 4” from DC to a 2 1/2 reducer to my TS and the difference is night and day. Not perfect but a lot better.

I am surprised nobody makes better flowing fitting rather then hitting a wall down to the needed size.

Waiting on more hoses and adapters to hook up other machines and leaving track saw on vacuum.

Thanks
