Spent the day doing a second cut on shaft blanks.
First cut takes them from 1" round or square to about .94" straight.
This second cut roughs in a taper to about 16.5mm at the tip end.
From here things move a lot slower <grin>.
Just thought others might want to see how much wood a well tuned Unique Taper/Shaper machine can chew off in one pass.

DAMN!
Did you slow down the router a little bit with that 6-wing cutter?
Kinda scare a 80 thou thick blade going 28K RPM.
I find the 2-inch diameter of that cutter a little tight so I have to move the taper bar out a little more.

It is running 30,000 rpm.
I do worry about the carbide teeth comming off and I think I remember someone taking one in the belly.
It has about 5/8" of wood to go thru before it gets to me but I am uncomfortable even when I put my hands into the box with that thing spinning. That six tooth cutter sure does a nice smooth job.
Bryan should ship one with every machine.

I've got a couple of saw machines that will take a 4/4 square to 8.5 mm in one pass but it's not needed. I've not had a piece of carbide come off of a cutter but I did have one of the copper commuters on a routers armature come loose, go thru the router and thru a wall once. That could spoil a persons day.

A table saw machine is the nuts for cutting shafts ... IMHO.
I wish I had the room for one.
Did you make yours, Dick, or did you buy it ready to go.

I built my own 10 years ago. I've got everything needed, except time, to build a 4 or 5 shaft/butt CNC saw type machine so as to iliminate taper bars. My machines have the saw built into them instead of using a table saw.

Dickie,
HAHA, how about the time you were using your radial arm saw to rip cocobolo boards into turning squares? That's the one you were lucky to survive! LOL As I recall the piece of cocobolo caught you a glancing blow, on the side of your head (near the temple) before going through the 3/4" plywood wall of your shed and landing in the yard! That was a little too close for comfort!
We've all had close calls, I guess, but that one of yours made me re-think the value of a radial arm saw in my cue shop! lol
just more hot air!

Ouch, glad the ol boy was alright. I enjoy having him around to talk with :) . the temple is a bad place to get hit. Guess the radials have alittle more kick. I had My table saw kick a piece of ebony out, and I still felt lucky I was standing to the side of It, even though It only stuck in the drywall behind me. It happened in a flash, so quick, reflexes would have done no good. Seems like I did'nt have My fence setup with the slight wedge, as not to pinch the piece or something silly like that.

Just out of curiosity, what size ( of motor is running the cutter 110V, ?? amps, do not trust spec-sheet horsepower numbers) ? The shaft spinning motor would not need to be very big, but generally speaking the volume of material you can remove in a given time is proportional to the power available to the cutter. Taking a huge depth-of-cut can be done, just at slower feeds than a shallower cut, for a machine of a given power. Now if that cut was done on a full 30" shaft in 5 seconds I'd be impressed. If that same cut took 10 minutes, I'd say you have a pretty wimpy machine.
Now I must borrow another sign off line ... more hot air !

3/4 HP Ryobi.
Maple's pretty soft when being cut with 6-wing cutter.
The 6-wing cutter cuts them into smaller chips compared to the 2-flute 5/8 bit.
You can hear the motor slow down when stressed out. You have to cut less when cutting purpleheart or rosewood or bocote.

It is a Roybi laminate trimmer.
The trick is not that it is cutting so deeply ... it is that it is cutting a 30" piece of shaft wood that deep without destroying it. Vibration and tool chatttering can get so bad it will cut the dowel into.
The pass takes about 5 to 6 minutes.

I was cutting boards into turning squares on my table saw. I pushed a piece through, reached across the saw to pick it up and droped it onto the spinning blade. It kicked back and caught me right between my belly button and you know where. The bruise lasted about two weeks. Good thing it was not a little lower or I would still be rolling around in the fetal position puking on myself.

How was your wife for two weeks?:D

Hi Willee.. is that bearing at the bottom of your tool a modification or does that machine come that way?
Just curious.. Tom

My machine does not have that bearing.

hello WilleeCue , why my taper shaper do not have circle saw?
and seems like I can not install it....:confused:

Hey Joey,
Do you happen to know what is the largest collet/shank size that Ryobi can take?

I believe willeecue has modified his Taper Shaper to use the 6 wing cutter, guided by the bearing in the base of the cross-slide. That cutter does not come with the machine - at least it didn't come with mine.

Hey guys, The Taper Shaper does not come with the lower bearing, Willee has modified his machine. He might be able to help you with this addition, if you are interested in it. The next upgrade from Unique is the High Speed Spindle to handle larger cuts on wood.

It doesn't.
It comes with a 1/4 cutter.
You can get a 5/8 or 3/4 two-flute carbide if you want.
THose cut very nicely.

Thanks for the reply (you too Joey !), and I believe it Willee. Just out curiosity I calculated the chip load ... a 6 'wing' cutter spinning at 30,000 rpm covering a 30" shaft in 5 minutes cuts about 0.00003" per blade pass. I can see how that would not put much strain on the shaft, it's nearly polishing :) . Now, for perhaps a crazy idea, but if going faster causes chattering, could a follow rest somehow be used to allow a faster feed rate ? Not only for the time involved, but for the tool wear as well. Of course I am not a cuemaker, just an amateur metal-hacker and occasional woodworker with dangerously little knowledge.

The blades are cheap. So, even if you have to replace them every two weeks, it wouldn't be too bad.
I get a tool push off though near the center of the shaft when cutting fast.
Maybe a light spring pushing a wheel in the backside of the wood would help.

I think one cuemaker uses a slab of foam to lightly rub against the back of the shaft to reduce vibration.

Call me crazy but I would think 5 minutes to make a pass on a shaft isn't too slow....I can't imagine any cuemaker being so rushed that 5 minutes just doesn't 'cut' it.....LOLz

I guess it would depend on how many shafts you wanted to make in a given period of time, and also the opportunity cost of having the tool occupied.
