Heres what came to mind.:dunce:

Lets hear some feed back.:cuss:

Link to bit.:mrgreen:
Irwin 1/2 x 12 Installer Bit [HN-38908] - $11.95 : Seven Corners Hardware, The finest quality tools, accessories, and hardware at the lowest prices

3in pipe, pink=reduction fitting or something like that(need holes for trim to go though), yellow=bearing(we have a big bearing shop close by), blue=cutting bit.

Metal pipe would be nice, but maybe the first one in PVC ??:confused:

Cutting platform, maybe lexan ??:confused:

Vac connects to bearing side, power with 1/2 drill ??:confused:


Second bearing on the motor side ??

I don't have any experience with trimmers but I think I get the concept. If your trouble is how to secure the bearing, why not just mate the outer ring to the inner diameter of the pipe and the inner ring to the drill bit with an epoxy like JB Weld. I've seen people hold together engine blocks with this stuff - it's stronger than many types of steel. You could pick up the JB Weld and bearings at your local auto parts store. So basically you would have the outer bearing race fixed in the PVC pipe and the inner ring fixed to the drill bit and the two inner parts could spin inside the outer parts. Here's a very rough sketch.

How would one of those tiny handheld and battery powered hedge groomers work? I think black and decker makes a rechargable one.... I'm not talking the big clipper that has the long trim bar that has 20 blade sets on it that you use to shape hedges around you home......I'm talking a tiny baseball sized one that has maybe 2 blades on it....Would something like that work??

That sure would be a easy way to mount the bearings, but we need to exacuate the cuttings to the vac bag, the hose dosn't have to mount to the end I'm going to look around, I'll get the bit and bearings today.

Still a little big but thanks a lot, Outlaw, REP+ for the effort.

Now that I think about it, it could be made to work.

Couldn't get the bearings in the same size O.D., but I'll deal .

$20 for the bit(9/16X18in.), another $30 for the JB Weld and bearings.

The bit is Irwin very good quality (they make Vise Grips)

The motor side bearing is a perfect fit, the tip side has a tiny bit of slop, maybe two thicknesses of paper all around.

I was thinking of using MarineTec, but I'm going with JB Weld.

Yeah, that JB Weld is good because it withstands high heat and has good resistance to sheer force. It sure does stink though. I think I could be more help if I knew more about the trimming concept. I've never trimmed a plant manually, much less with a power trimmer. Let me see if I get the idea. A branch, bud and leaves and all, is put in the PVC pipe and the drill tears the bud from the trim. Then the trim is vacuumed out. Do I have the right idea? It hard to see from the product pictures of those trimmers exactly how they operate. I like Irwin tools, too.

Been playing around, making a mock-up, using hot glue for now, I can peel it off if I want to change something.

The trim can't go past the front bearing, so I'm going to put a Y-fitting then another piece of pipe to hold the rear bearing.

Mared, the idea is, cut off a branch, big nugs. Rub lightly over slot, vac pulls in smaller leaves and the bit cuts them off,the bud won't fit though the slot but the leafage will, I'll whack the fans off by hand.

Trimming SUCKS, I love to do everything BUT THAT.

Spent 3 years laying-up fiberglass boats, going to smell good.

Ohhhhhh. I get it now. As long as everything is sealed tight except the one end and the slot, it ought to work. You're just planning on pulling the vacuum through the hole in the bearing opposite the drill side? That should work even with the bit spinning in there. I'm interested to see the results.

Not to pretty, but I don't want to cut off the excess glue till I disassemble it.

Tried hooking the vac(12amp) to the Y works very well, lots of suction at the slot, a small vac will work nicely I think.

Spun it with my 1/2 drill, spins good.

I want to get a couple of clamps for it tomorrow, make a mount.

This is a shake-down version.

Another idea, laminate an eraser shield to the bit side of the lexan(epoxy and the seal-a-meal). I'd like a spring steel slot.

I make small carbon fiber and fiberglass parts for my toys that way.

This thing WORKS !!

Vac is too strong, its a full size upright.

I'll try to make a movie, I couldn't post the last movie I made(it was from my camera) I don't know why.
