Spent a lot of time looking at the mess that was my 80mm spindle with dust extraction hose and water lines ez-tied together for a temporary solution. Could not wait to make it better, and after a considerable amount of time staring at the machine, I came up with what I think is a very nice system that works perfectly.
I upgraded the router power cable chain to a 18x25 id to fit my double shielded spindle power cord and the 8mm water hoses, as the stock chain was a little too small.
I then modeled a 80mm modular clamp for the spindle and designed a new hose bracket for it with a vertical cable chain bracket. I took a section of the 18x25 cable chain and ran it over the top of the HDZ and secured it in the back to my wire cover assembly with a nice sturdy bracket, it all bolts together perfectly for a secure fit. I also modeled new hose rings that bolt to the cable chain in between the links so they still articulate.
Photos show the Sweepy all the way up, and all the way down, and with the HDZ in it’s lowest and highest position.
Thank you Bruce, I hope the parts serve you well. I was recently contacted by another forum member for the models. These were some of the first 3D printed parts I ever designed. I have learned a lot since, and they could probably use an update one of these days.
2 piece rings you don’t have to shove the hose through and better attachment methods come to mind…
I intentionally made them a tight fit so the hose would stay put where located, I would slinky up the hose and slide it through a little sideways to insert it… I will work on an update in a few minutes.
I think it is a decent upgrade, made a few small revisions for the next version. The Nema cap is now a clamp, the tiny top screws were not a great fastener, though I left in the holes…
Slightly heavier then the old version with the added weight of the hardware. Much easier to adjust with the 2 piece hose clamps.
Was getting some flex due to the thin metal brackets on the back of the HDZ were not designed to support a vertical cable chain with a triple shielded wire and two water lines. Old design was sandwiching them for support, redesigned and replaced the original metal brackets with a more robust 3d printed bracket and connected it to the Y stepper for stability.
