@aeversme Thank you! Looking forward to seeing the model. @DougJoseph I was wondering if a top mount for the spindle can be integrated with the cable chain mount that you designed a year ago, cable chain already on my LR3. I think that such an addition will be great!

Today, I worked on the Linear Rail Mount with a slide latch. I re-drilled the four rail holes on the mount to 4mm to accommodate brass M3 inserts, and it was so easy not to think about nuts during installation!
I also cut the EVA Form bristles with my daughter Cricut, which makes it easy and fast. Laser will come later on LR3 using the Kinematic tool mount.

Thatâs great. Youâre up on me there because I did not worry about nuts or inserts. I just let M2.5 screws cut their own threads in the plastic and called that good.
HEADS UP to anyone helping test this or planning to
I need to remix and reprint the âshoeâ itself (thatâs the same part that gets the EVA foam bristles inserted into it). Hoping to get to that today.
Last night / wee hours of the morning, I finally got to some more progress on prepping for trying this out.
The shoe itself, once slid on, is long, and the business end of it is hanging out there, acting like a bit of a lever. It can get shifted around (laterally, âleftwards and rightwards,â in the same XY plane as the material) pivoting from the point back on the end of it that âslides on.â This means it can collide with the core when it is getting âretractedâ upwards. I need to remix it to have more clearance.
Just wanted to mention this now, even before I remix it, in case someone is prepping to print it, so they know to hold off a bit.

Thanks, Doug. I am postponing the printing of it until you give the OK.

Looking forward to checking out the remix!
I have posted my hose adapter here: Printables. The slots for the c-clip are a little large; if someone wants to remix it to be more precise in relation to the c-clip and in terms of distance between the c-clip holes at the hard stop in the dust shoe mount, feel free. Itâs probably not as slick an interface as a shop vac hose, but it ought to do the trick. Havenât tested it live, though, since progress has been slow and my LR3 is not back on its rail yet.

Cool! Thanks!
Iâm trying to publish the remixes, and currently hitting a license roadblock. I have posted a question to Ryan about it.
OK, I went ahead and revised the license on all my upstream remixes to match what Ryanâs original Makita mount currently shows as its license, which is the âShare Alikeâ one. I was then able to get past the roadblock and set the newest revision on this latest remix to the same.

Change log:
- October 3, 2023 â Revised the Shoe Body and Show Lid based on actual testing. The shoe itself, once slid on, is long, and the business end of it is hanging out there, acting like a bit of a lever. It can get shifted around (laterally, âleftwards and rightwards,â in the same XY plane as the material) pivoting a little bit. This means it can collide with the core when it is getting âretractedâ upwards. This remix added more clearance, to help with that. I also revised the Slide Latch part, again based on actual testing. I made the âhookâ part of the latch stronger, longer, thicker, etc. To reiterate, these are the revised parts:
- Shoe BODY (for Makita, for 2.5-inch Hose) (qtr open) v1.0-A.stl
- Shoe BODY (for Makita, for 2.5-inch Hose) (half open) v1.0-B.stl
- Shoe BODY (for Makita, for 2.5-inch Hose) (full open) v1.0-C.stl
- Shoe LID (for Makita, for 2.5-inch Hose) v1.0.stl
- Slide Latch v1.0.stl
Thanks, Doug. Printing them now.

Just completed my first couple of test cuts with the new floating Z dust shoe arrangement. Video forthcoming (part 3). Definitely all but eliminates wood chips / saw dust getting out onto the table/workpiece. Whether or not this âsled shoeâ approach is good for the long run will be known over time. If a maker with this setup happens to be doing a job that is likely to have some of the cut pieces âpop upâ out of their slots and potentially collide with the shoe, then using the built in latch to hold the shoe up would probably advisable. For now, Iâm thrilled with its functionality.
ive try it and it work like a charm in a dewalt 611 with a bit a modifications i made my hose from tpu
thx lot for your work doug

I just finished editing the Part 3 video on this, and itâs currently rendering. My initial testing with the â1/4 openâ shoe has led me to think the best option is a shoe with the very same amount open as on Ryanâs original @vicious1 design, so I wonât be testing the â1/2 openâ or âfull openâ options. Just a heads up. The video will hopefully be published later today, as soon as I can get it uploaded and processed. Iâll also be making a thumbnail image for it.
The video is currently being uploaded and processed by YouTubeâs servers. As of 11:40 am (Eastern US), itâs not live yet, but when it is soon, it will be at:

Nice! I have only printed the âfull openâ shoe so far, but Iâm going to print a â1/4 openâ shoe right now. Once my LR is cutting (someday! sheesh), Iâll try them both out for giggles.

Another great video Doug - I would love to race out and just build one, but Iâm going to stick to my guns and start with the stock approach for now.
I am really interested in âdustâ collection efficiency so need to have a baseline before I start - itâs all a bit fascinating!!

Thanks!
To see my baseline, consider the video evidence I published in part 1, starting at about 54 seconds in:
Iâm worldâs ahead of that baseline.
Update
Printables listing was just updated.
As of October 4, 2023 â build and install now complete, and testing done (see video, part 3), and as a result, I am removing the prior three options of dust shoe (Âź open, ½ open, and full open) and replacing them with a single shoe that has about the same amount of opening on the bottom as Ryanâs original design.
