I had to change back to the regular Sweepy due to a part interference with a deep cut.
I put the regular Sweepy on an my vacuum hose collapsed due too much restriction.
Has any one else found this ? The hose I have is 4", spiral wound, semi clear, very supple.
It came from a shop that cut graphite. No material sticks to it. I do not want to change the hose.
I am thinking of drilling whole in the regular Sweepy bottom half to allow more air. It will need about 2 sq inches of holes to be the same area as the Deep Sweepy
I have not experienced the hose collapsing, but I hate the noise when using the regular vs the deep.
I was cutting some pockets in MDF yesterday and somehow my deep Sweepy came off and got caught under the spindle and the bit chewed on it a little. I was standing right there but not looking so I don’t know what happened. I was able to pause, remove the sweepy and finish the cut which only had a minute left. It wasn’t a super important job so I let it roll and luckily nothing was knocked out of alignment. I stared at the workpiece and clamping and still have no idea how it came off unless it just wasn’t seated properly to start and the brush fibers got snagged between the edges of the piece and a clamp.
Anyway, I switched to the regular sweepy later for some profile cuts in plywood. The bit protruded about 3/4” or maybe a little more from the bottom of the brushes. I was surprised at how well it actually sucked up the material.it was better than I would have expected from that distance on the initial passes. I think that since I switched to a water cooled spindle the vacuum is more effective as it isn’t fighting with the airflow from the router.
I had a recent problem (twice in a row, junked the wood) where the Deep Sweepy brushes had folded in and reduced the OD opening by +50%. The wood particles filled up the rest of the opening, sucked the vacuum hose tight, pulled off my spindle mount and got in the way of the transom. Dang …
The solution was to trim the brushes back so the opening was clear. I generally have the brushes at least 1/2" off the part, that collects 90% of the debris. I also allowed more slack in the hose loops to be more tolerant of compression.
Now I know to watch the hose. So when I put the regular Sweepy bottom on, I saw the hose ( heard the change in pitch for the vacuum) and just went with out for that cut.
