J_R's latest dust foot

[J.R. Hatcher]

Life needs to be convenient ;). This is why I made changes in the dust foot.
Dust foot 5th gen:

2678 2679

Most of time I had to raise the Z so I could drop the dust foot to do a bit change :( ..... no more :D.
The black knob is spring loaded and keeps the front half in place until pulled about 1/4", to replace the front you just push it back in until it clicks :cool:.

Nice work J.R.,

It's interesting to see the different methods/styles individuals come up with for the dust foot.

J.R. any chance of posting dxf's of that snazzy dust foot?

[J.R. Hatcher]

Alan this is it. I hope it works as good for you as it does for me. If you need any more pictures let me know.

J.R.

What material did you use to make the skirt around the outside and how well does it perform now that you have been using it for over 6 months, are you able to compare it to a brush type of skirt?

How did you spring load the black knob to lock the front piece in?

J.R. that came just at the right time thanks:D

Alan & Hennie, The material is used for the inner door of a walk in cooler. It's the strips you walk through and it works great for the dust foot. Alan I've never used brush material so I can't compare. A few months ago I needed to see the bit as it was cutting, so I removed the front of the dust foot ..... it has not been back on since. It sucks much better without it. With it in place the air is pulled from all the way around the foot, 60% or more of that air is not pulling dust from the bit. With the front removed almost all of the air enters there and passes the bit, making it much more efficient. The next generation will get the sides extended a little and will not have a front. So you don't need the little black knob. :D

Interesting, thanks - back to the drawing board(screen) ;)

That is typically called "flexible PVC" out here. Cape Plastics sells us a lot of 5mm thick sheet, I don't know if they have thinner.

I'm not in the shop, so my guess would be 2mm to 3mm and it's clear.
