Title: Made a dust shoe for my router.
Post by: ger21 on September 07, 2009, 01:12:16 PM: Needed to keep the dust in check, so made this for my second project.

That looks really nice, Gerry.

It works really good, too. :) Here's a video of it with NO dust flying around.

Where do you buy the brush strip?

Nice job, look like reel alu.

Nice work

Where do you buy the brush strip?

McMaster Carr. Was only $10 for the 3 ft I needed.

May I ask what you think of the LoveJoy couplers? If you went to buy a new set would you still buy those or possibly it's too early to tell?

I'm debating whether or not to buy the helical, the Oldham, or the LoveJoy types.

Thanks,
Dave

Post by: ger21 on September 08, 2009, 12:17:12 PM: Actually, I have helical couplings on all the other screws. I got the helical couplings for $5 each a few years ago, after I had purchased the Lovejoys. For the Z axis, it seems to work fine. Backlash is less than .005, but I haven't measured it. I zero my Z with incremental jog set to .005, and it moves both diections. :) Although the 1/2-10 acme on my Z would show less backlash than a higher lead screw.

I actually swapped it out for a helical coupling, but it wouldn't run with the helical due to resonance, possibly caused by some misalignment. My Xylotex suffers from resonance badly on all the axis, but all the other motors have dampers that get rid of it. The Z axis has a single shaft stepper, so I can't use a damper. Fortuantely. the Lovejoy seems to cure it.

If I had to pay full price for the helicals, I probably would use the Lovejoys, for 1/5 the price. But the new machine I'm designing will be belt drive, so it won't have any. :)

If you look at the Joe's cnc's at CNC Zone, Joe cut's new, tighter fitting spiders out of Delrin or HDPE to make them virtually backlash free.

Post by: Ron Ginger on September 09, 2009, 10:52:41 PM: How did you hold the brush strip into the base plate? I see the groove but dont see how its held in.

Post by: ger21 on September 10, 2009, 05:36:12 PM: 5 minute epoxy.

Post by: Garyv on November 02, 2009, 06:27:04 PM: Rats now I have to re-design mine and get the bristle from McMaster Carr..
Thanks I have been looking for that stuff, and you have made exactly what I need to make for my router , the MDF dust is killing me in the garage just went to harbor freight and got a 99 dollar dust collector today and drawing out my plate now going to add a .250 groove for the bristles..I had eve looked around and was going to cut some hand brushes in strips.. I have used heavy clear shower curtains in the past but they tend to fold up after the vacume hits it and the brush will sweep out beter than the plastic..
Thanks , always get good ideas on this forum for building

Post by: ger21 on November 02, 2009, 07:23:21 PM: The brush I used needed a 5/16" slot. Also, I used .014 dia. bristles, but will go with at least .020 next time, as they're a little too soft and occasionally get twisted together.
Title: Re: Made a dust shoe for my router.
Post by: Garyv on November 04, 2009, 06:22:37 PM: Well I got my brush material from Mcmaster carr today , man fast shipping ordered monday got it today..Great stuff , just wish I knew that there was a 1/16th wire in the frame holding the bristels in after my first cut the hait went flying , then piched it off before cutting the next one..
Had to clean up all of the mess from the starboard I cut it from but now next cut get to use the dust collector..
I made the pocket .350 wide and the brush was a good press fit so no glue had to be used..
Thanks
Gary

Post by: Sam on June 05, 2010, 12:42:27 PM: I think I'm about ready to get started making one of these. Besides the .02 bristles, is there anything you wished you would have done differently? Adjustable height? Quick release mount? Anything?
Title: Re: Made a dust shoe for my router.
Post by: ger21 on June 05, 2010, 12:56:24 PM: I made some spacers to adjust the height. Be aware that if the bit is below the brush, the shoe becomes practically useless, as the chips will fly everywhere. You need a good seal to the table.

Quicker release would be nice, but I don't change tools a lot, and I can get mine off on a few seconds. Next one will probably use magnets, with maybe a single thumbscrew for insurance.
