Thread: My Clear vue installation

A little more information on the double joint. When this small gate is in use the 150mm duct is only open to 120m duc.t So there is plenty of suck for both ducts. The small duct in photo is more like two 45 then a 90 degree bend.

All this aside there more then enough suck at the cutting point to pull all dust away above the and below the table. I just hope the paint on the inside of the bandsaw covers is not pulled of by the air flow

I am most happy with the baffle plate that I put under the table it has work to date 100%. No small chips getting between the bottom wheel and blade.

Hi
Got to used the downdraft table (ddt) on a project, machine sanding, hand sanding and then spray painting. No dust or fumes in the shed. After painting I left the CV on low RPM for a while to take away the gassing off from the paint. Happy with this feature.
Very pleased with this bit of gear, best bit it cost me nothing, made it from cover sheets of packs.

Got a little more done on the ducting. This should be the last bit, I hope.......
A new drop for the bench drill and bracket the ducting to rafters with metal straps which replaces the rope and string.
Have made the new gate up ready to attach, just try to work out the best way to mount end of flex near the drill bit. Anyone got a suggestion here???? Also thinking a grate of some sort might be a safe idea.

John Samuel has a done a setup for his DP that seems to work. I still haven't done mine because I haven't been use the DP much with wood these days.

Rusel,

I use a Big Gulp from CarbaTec modified from 4 inch to 6 inch pipe. BobL tells me a bell shaped end is likely better, and I plan to replace the Big Gulp with a piece of 6 inch PVC pipe thermoformed to a bell shaped mouth ... one day. If you decide to go down a similar path a thermoformed bell shaped end is also a cheaper option.

It does not pick up all of the big drillings. However, I tried several things, including the shop vac and after deciding that it was the fine dust I was after went for the solution in the pic. The big drillings it sometimes does not pick up don't worry me ... I am not breathing them and I grab them next time I have the shop vac hose in my hand.

It is brilliant for the fine dust. I use the drill press to sand small radius curves, like those on cabriole legs, and it does a great job. Leaves no dust at all on the table or in the air. The blast gate in the pic has been moved adjacent to the overhead main.

Rusel,
My recent testing on dust levels while using a DP may prove of interest to you.
They are posted here.

In summary, it appears that compared to other WW activities relatively little fine dust is produced when drilling and that it needs very little suction/draft to collect that fine dust.
However as JS and FF indicate good suction helps keep the area clean of chips which has definite advantages.

Hi John,
That's a neat looking blast gate, I am trying to recall whether I saw them in your system when I was there, obviously made out of perspex, Did you make it? Buy it? A few close ups would be appreciated if possible please.

They look like Clearvue blast gates to be - although JS is a pretty crafty fellow so he might have got extra crafty with these?

Hello Pete,

Those blast gates were there when you visited. They were bought from ClearVue.

They work a treat, too. Did a static pressure test with about 2 ft of pipe sticking out from the cyclone. Did another with the ductwork hooked up. There was virtually no difference at all, so they do not leak.

On the road right now. Will post close-ups next week.

Thank for the info guys most enlightening, but I had made this up before looking here, Seem to work well as I only use it for big chip drilling.

Final finished of the exhaust ducting and sound reduction, before this it was just some bits of mattress foam leaning around the ducting.
Using my phone at 3mts the sound level where, With no box and stuffing around 75 and this dropped to 65 with the completed box.

Hi Rusel, can you please tell us what materials you have wrapped the exhaust pipe with?

Thanks

Started with Johns method of a 300mm AC flex insulated duct over this with a 600mm of the same then some old foam mattress blocks and then chip board, would have used mdf but when it free.......Most of the noise come from the exhaust port straight out and out of the top part of the elbow of the ac ducting. So this is where I double the foam up top and at the top right side.
Well now it is inside the box I can us this for hanging things of. First will be the bandsaw blades. dropsaw blades and table saw accessories.

Looking good!
