  • Chuck to hold a regular pencil

    I have a 1200 lathe I just bought. What chuck would you recommend to hold a regular lead pencil? I assume I need something on both ends but the end without the motor would have to be a chuck that turns and be free wheeling on a bearing? I also want to know what tool would be best to cut into the pencil at 1/16" or 1/32" of an inch. Any info would be greatly appreciated.

    Re: Chuck to hold a regular pencil

    first I do not have a 1200 lathe, I do have a wood lathe and have used a number of wood lathes in the past,

    but it looks like it uses a #2 Morse taper on the head stock and the tail stock,

    I would probably get a 1/2 drill chuck on a #2 taper, for the chuck IF I am understanding what you want to do, a 1/2 chuck should easily hold a pencil,

    for the tail stock end,
    http://www.grizzly.com/catalog/2010/Main/129 here are some live centers, but I would think one would need to make some type of adapter to make it work,
    even the delta center, really does not have any thing that would work with a pencil http://www.dynamitetoolco.com/Delta-...del-46-490.htm
    one may just end up having to make some type of tail stock to work some thing with a hole in it, and put some wax in it to lubricate it, may be another chuck and put a sleeve bushing in it to support the end of it,

    you could look up pen lathes, but it appears on pens you drill out the center and put a mandrel though to support the wood when turning,

    it going to be tough to really work the pieces that are that small, you many end up sanding and filing to complete them at that small diameter, If you go to the grizzly page and go a few more pages there are some micro tools for, pen turning
    also there are some other types of three and four jaw chucks,

      I don't do any wood turning but I imagine the principals would be the same as turning small diameter rods on a metal lathe. To turn a diameter as small and fragile as a pencil I think you will need a follower rest to stop the pencil from flexing and shattering the lead. I think you will also need to drill out the end of the pencil the same size as the live centre spur so you don't split the pencil trying to push it into the spur

        Can you send me some pictures of what "follower rest" would look like?

            some follower rests in wood working use rollers on the points that rest on the work,

                Re: Chuck to hold a regular pencil

                I am now looking for a what could be a "pencil sharpener" that can grind down a pencil evenly instead of grinding a point. I want to stick the pencil in and have it grind it evenly about 1/16" deep the entire circumference for a length of 1 9/16" of the pencil (normally 7") . Any idea's of a machine that I can look at?

                  make a tool similar to a "pencil sharpener" or a "tendon jig"

                  by cutting a block of wood and drilling a hole in it and then mounting via a second hole a lathe tool or chisel in it one could make the cut, by spinning the dowel,
                  http://www.rockler.com/gallery.cfm?O...Select=Details


                  the other thing I would consider, is some thing like a "beall threader"

                  it uses a router to cut and the dowel is turned by hand slowly,
                  here is a pictorial demo of the unit,
                  http://www.woodshopdemos.com/beall1.htm

                  I do not know if the actual beall threader would do what you want or not, but I think one would be easy to make that would do what your wanting to do out of some scrap laying around,
                  link ot a beall threader,
                  http://www.rockler.com/product.cfm?page=9899

                  if one just make one by hand and mounts there router on top drills a hole the same the pencil, set a bit to the proper depth, and turn on and insert the pencil and rotate by putting a stop out back you have controlled the amount of depth you cut off,

                  if there is just a few, I would my self most likely just sand them in the lath, but if I wanted to make many I would my self make a Beall type threader jig and use a router, to do the cutting

                  here is the same concept but on a larger scale, using a router table,
                  http://www.rockler.com/product.cfm?page=11055 the concept of how it works


                  as far as it goes one could make or get a second rounter base and make a unit that just attached to the bottom of router out of a few pieces of scrap around the shop.
                  some thing like this,
                  picture found on http://www.woodworkforums.com/f44/threading-wood-8513/

                  I think that the above would be the easily way, the only other option I could see is a msc type fluting by jig on a lath, so one can cut it with out the stress associated with normal turning, but instead of having the work stationary have it turning, http://www.mlcswoodworking.com/shops...d_fluting.html
