Re: Clearvue shaker?

 

Installed this before the official accessory existed....Amazon buy,pneumatic vibratory mechanism GT13. I consider it necessary equipment, esp. if you overload your cyclone ever or you don't have a perfectly sealing dust bin like my current one.? There are electric variants that also have merit. Also prior discussions if you search back a couple years in the messages.

Hi Larry,

Bridge City Tools sells a less expensive version. I have not tried this but it is very similar to the design of the Harvey version and only $49.99.

Correct, the bands have a North Pole arrangement in the banding that repeats every 5mm, so cutting it would make it almost impossible to get a continuous correct reading across two pieces.

Re: Selecting a dust collector

 

To add anything that might be helpful, I am currently in initial installation trials of a Oneida Supercell Turbo for a specific situation. It top?dead heads in the 90+ in.H2O range (WOW!), the tradeoff is that the head/flow curve puts it usefully in the 400-600cfm range for most tool?ports on this setup. It requires specialty hose to withstand the suction levels.?

I also very much appreciate the self-cleaning filtration feature built-in after feeling the pain of the "oops too full" aftermath of my cyclone filters (another reason I'm careful not to plane a full 5mm cut on wide boards on my AD941, but that's another story)

So far it has been massively impressive at point-source collection. But also not nearly as exciting at working-area collection. It's just different circulating 1200 cfm+ versus 400+ cfm in a work area. To points I recall from Pentz's documentation, that additional recirculating flow in a work area is a big factor in reclaiming the fugitive?dust that doesn't get caught the first time at the source. It's a trade off with the same power capacities - head vs. flow between the two systems.

I will say the biggest improvement ever made to my multiple clearview setups was adopting 6" drops and 6" flex all the way to the tool ports over?6" drops and 4" flex I originally thought was adequate. The flow performance is mathematically improved as expected, but in practice it takes a machine like a bandsaw from 70% dust captured to 90+% at the source. Another example is that you can lay a 6" open hose?on the floor working with a router on a work table above, and the flow visibly alters the trajectory of falling particulates. That never happened with a 4" hose unless already close by.

You have to be careful on your main duct size. ?I considered this in my setup. ?If you look at my pictures, I have a very short section from the collector where the main is 8¡± duct (right before it connects to the cyclone). ?Then it branches/splits off into different 6¡± main ducts. ? You have to make sure you have enough velocity in your system to pull the sawdust horizontally along the main duct. ?This prevents debris from building up in the duct (this can be a fire hazard). ?If you have a 5HP dust collector and expect to run more than one tool at a time, then an 8¡± main duct can be good ¡ª to a certain point. ?If you are running a really long 8¡± main duct and then do a 6¡± drop at the end, that¡¯s not really a good design because you likely will not have enough air velocity in that 8¡± section of main duct to keep it clear of dust/debris (does this make sense?).

Re: Selecting a dust collector

Thank you Joe,

When I had my?Sawstop, the overarm dust?collector? hose was 2" or something like that and did a poor job,especially MDF. I made my own overblade?dust cover from 3/8" plexiglass, suspended from the ceiling with a cantilever lift arm. (you can see many examples on youtube.) I also added?1/16" side guards on the sides that could slide down to the tabletop if I was edge cutting. This was an amazing?improvement.? I ran 4" hose from the overarm to a 4X8 wye.? Locate the 4" port on the overarm guard just past the apex of the sawblade. I found that the majority?of dust is flung from the top.

My Plan is to 3D print an adapter from the Felder Overarm and attach directly to the plexi-portion. Not sure about the configuration yet until I have the saw.? I will run 4" at least and possibly 5" from the overhead guard.
I am amazed at the lack of dust collection optimization on the Felder saws.? They make a good product overall.?

When I get it complete and tested I'll send you and this forum pics.....

Cheers.
