Re: Pulley for the Woodchuck

Yup, I use the pucker factor as well, it just has to feel right.  
Sometimes the vibration from out of balance could be caused by wood 
density even in the same log.  learn to feel the speed, feel the force, 
it's strong with this one.

What's the diameter of the piece you are turning?  The latest 
instructions are to cut from the headstock to the tail stock using 
1-1/4" flat bottom router bit.  The spindle would be turning counter 
clockwise and the router is offset towards the back by a 1/2" or so.
The speed was based on a average of 120 ipm (inches per minute).  The 
diameter of the piece will affect the speed. Honestly, do what feels 
safe.  I use the tachometer in my butt cheeks, if it's going to fast 
and my cheeks tighten up, I slow down the speed :-) !!!  How's that 
for advice!
By the way, the flat bottom bits have to be flat.  It is very common 
for "Flat Bottom" bits to have a 1 degree taper towards the inside, 
and that will not create a smooth surface.  You will see ridges all 
along the piece.

I hope this help some, if not keep the questions coming.

Bill,
I am using a straight 1/2 inch bit, cutting from the side. *_All I
do at the present time is to experiment. _*Has anyone found that
300  rpm is too fast, and if so what happens, The longest length
that I am turning is around 2 feet x 1 1/4 inch dia.
I am taking it steady on the travel as I do not trust the limit
switches too much.
If travelling from tailstock to headstock is there a best way to
turn the spindle,,_clockwise or anti clockwise_
The router cutter is rotating clockwise as seen from above
(Tritons largest router ) and not trying to walk into the wood
Regards to all who are giving me guidance

Sounds good 300rpm is faster than i would use but if i
remember Tim suggested it would work ok. 200 is as fast as I
would go

But your saying you have been using 300 ok, great with a slow
saddle feed you must be getting a nice smooth finish

Are you using a surface planning bit or perhaps a corbox bit?

Bill

Have checked the speeds, At 50 cycles, ( that is the U.K.
supply,) the spindles RPM is 227 and the revs that I have been
using so far ,are 300 r.p.m. approx.

I do not use it for more than a few minutes, but keep all
bearings well oiled.

My pulley is a bit too large in dia.  Will turn it down to fit
the 50 cycles/ 300 rpm.

My inverter does, and will go up to 75 cycles per .min. So
could get the spindle even faster,,, maybee get vibes!!!???

I am still working on these skittles out of some quick grown
softwood, awful stuff, can't wait to get back to oak and beech.

I quite like this old Woodchuck, it's growing on me. Have to
work on a rotary table one day, my metal work one is too heavy
to lump around.

Cheers

Richard

Hi Bill

I will put the Tacho on it today, and will let you know,,
however the inverter has a potentiometer on it ,so I can vary
the revs. As long as it does not over heat it can go to nearly
zero. The spindle as you know does not need a lot of power. (
also gives the good Wife's arm a rest  )

The ply is secondhand and is the best I have ever seen ,or
used, I think it was ex, film studio or something similar,
shiny black on one side and mat black on the other, when I cut
it ,I have never found a void, all well glued.

Looks good do you have any idea how many rpm it spins the spindle?

Hi All

Today I fitted a plywood pulley to my old Woodchuck. It drives
the spindle via a 3 phase motor using an inverter to control

I am going to be ordering some new half nuts as well as a couple lower 
mounts, I will get the ones you will need for your legacy as well as an 
old style like the one you have in your pictures.  I'll take some pics soon


Mike OK

I, as you probably know, I  have recently bought an old Woodchuck. I 
paid £500 for it, but it did include a Transformer and a router ( 
worth about £100 for the pair )

The seller stated that he had paid over £2000 for it when new in 1994.
Although I am pleased with it, £400 when new would have been the right 
price for it. !!! ? -- Engineering wise, it is very poor quality,just 
basic materials.
What I do like about the box section tube that is used in it's 
construction ,is that enables me to add my l_ittle_ modifications to it .


I notice that Mike has a similar Model and he has also, has done a few 
Mods to the Woodchuck.
Well,, what made me Post this, is that ,   I am slowly reading all 
the posts on this Forum, and one that I found interesting was dated   
  4/26/07 interesting I must say.


Curtis very kindly threaded two pieces of Delrin 4 t.p.i. and sent 
them to me here in the U.K.  Unfortunately the overall size was too small.
Today I am going to make a clamping device so that Curtis's time was 
not wasted.
I did write to someone called Cindy at Legacy,  Re: half nut but no 
reply,  Good business  technique  for future custom ,!!!
 Meantime I will keep on modifying this old Woodchuck of mine to make 
it more user friendly .
*_I find that if it had been perfect I would have been more 
disappointed, Hence no CNC for me in any shape or form_*

Kind Regards, and many, many ,thanks again Curtis
