Re: Boom Arm progress


 

What I need to do, is extend the plates mounted on the arms, further apart.? That will give more room for the hose and not have it pinch as it shows. I was experimenting at the time I did all this and did not have a hose to test with.? There is no sag at all with the boom arm I have now and it's holding the dust hose, a festool cord with an extension cord for it and a solo extension cord.? I also had an air hose in it as well.. no sag at all

I don¡¯t know that one style bearing is better than the other. This is a low speed operation that isn¡¯t really meant for either type of bearing. Did either one sag less than the other? Kind of hard to quantify that with one being wood the other being metal. So just go with whatever is easiest and simplest to do.

The knuckle using wood is wider than what Randy made with aluminum. ?I did not yet see how the hose would work with the wood version yet. ?That is next as I will make "real" arms with pipe and hose now that I have the knuckle worked out. ?In addition to the wood version having a wider knuckle, I extended the top and bottom pieces out farther and that gives more room for the hose. ?In Randy's version if you will note, the gears are cut. ?I was planning to not only have the arms back a bit farther on the extensions that attach to the top plates, but also notch out a little on 1 side of each arm (as shown in the black lines) so the flex hose can be a bit longer so that ?the flex and compression will not be over such a short distance. ?Once I try that out, I will see if I need wider top-bottom plates.

Any thoughts from anyone on the 2 options for the bearings? <Center flex copy.jpg>
