Planing the end grain of a pencil sized tree core
 

Does anyone know if it is possible to make a flat surface on a pencil sized, 16" long piece of end grain using a hand planer? I am trying to count very faint tree rings on a sugar maple without using sandpaper, which clogs up the pores with saw dust. Would a hand or electric planner catch rather than cut, or create a rough surface when viewed under a microscope? If anyone knows of a better method then please let me know.

Here is a link to an image of what I am trying to create an even and smooth surface on:

I would think that a stain would help see the growth rings. That's
its purpose, though perhaps a woodworking stain isn't the best
solution. Biologists have a number of stains they use for this sort
of thing. You might try your state's extension service.

I have used stains to help clarify the tree rings, but it is only after sanding to 1200 grit that I am able to see the rings. I only use stains if the sanding is not adequate enough which is rarely the case.

Dave Picciuto got pretty good results using both sandpaper and hand plane:

Got a microtome? Or a sharp knife or chisel? Razor blade?

Is a microtome a place where really short people a buried?

Oh wait...that's not a b. ;-)

A SHARP hand plane, adjusted to take light shavings, will work very
well. To avoid breakage, I'd make a jig to support the core. Dado a slot
as wide as the core in a board, but shallower, with an end stop, to hold
the core in place as you plane off the protruding top. Or build up a
slot along a core by tacking slightly thinner strips of wood alongside.

I would try a a quality card scraper before I'd try a hand plane.

Have you sharpened your core sampler lately. Hone its cutting surface.

Is getting/having more than one core sample possible? I'd try Larry's (very sharp plane, etal.) suggestion and, maybe, wet one sample... see if that softens the fibers for better/best/easier planing. Slow, not fast, planing strokes?

If the log/tree has some significant age to it, I'd like to see a pic of the log/tree/snag. I enjoy "visiting" old grandpa trees/snags and the like. When I come across old magestic(?) trees, I sometimes imagine what stories/life they could tell or have experienced.

Thanks for the suggestion. Do you have any recommendations for a brand or type or hand plane I should use?

Planing the end grain of a pencil sized tree core
 

Three things I'd try:
Bore a hole in a wood scrap, put the stick in and wedge it, and fill with paraffin wax. Then,
with a heavy workbench vise, you can hold it still for a swipe or two with a sharp plane.
Low-angle (block) plane would be suitable, maybe a final pass or three with a card scraper.
Hole, wedge, wax again, only this time make a crosscut pass with a steel plywood blade in
a table saw.
Hole, wedge, wax again, only this time make a light pass with a straight carbide router bit.

Planing a loose knot is a close approximation to the task you have ahead of
you; making it a NOT-loose knot would be a high priority.

This sounds like instructions for planing the end of his "stick", like the end grain of a dowel. Am I thinking correctly?

I think he wants to plane along the length of the stick, which is a core sample, which the end grain is along its length, is perpendicular to the length.

That's correct. Wit3rd, are you thinking of encasing the core in wax and then shaving off small sections with a planner?

I've never heard of a vacuum pot before. Is that needed to stabilize the wood in resin?

Ah, the LENGTH. In that case, forget the microtome et al, a hand plane will
do the job but it must be sharp. For what you want, I'd think a block plane
would be the thing, just rig some way of keeping the core immobile.

Ok thanks, i'll look into that.

For most species I can see the rings despite the saw dust. The reason I want to cut rather than sand is that it will save time, money, and provide a better image when looking at rings that are only a few cells wide.

Easy to duplicate. Take two sticks and place them on either side of the
work to be planed. Somehow (ok, this part isn't so easy) hold the core
steady and run the plane along with the smooth parts of the plane running
on the sticks. A block plane would be ideal, but a good jack plane will
be of some use.

Lee Valley has a variety of planes that are well worth looking at, from
the really inexpensive miniature planes to the unbelievably (until you
try it) expensive ones. The most important thing is getting a sharp
iron. If you can sharpen, you're all set. If not, well that's another
thread or 20... I'll just say for a standard plane iron the Work Sharp is
as close to "no experience but nicely sharp" as you can get.

If you actually want to save the slice, that will take a little more
effort.

I have already made a vice for the core. Any recommendations on the size, price, brand, or angle of the plane? I need to be sure that the plane will cut the wood without sacrificing too much money to find out it does not work as well as sandpaper.

I used a phloroglucinol dye to distinguish the lignified wood from the non-lignified wood. Still, I need to be able to slice the core to remove the pains of going through all of that sandpaper.

I would think that a stain would help see the growth rings. That's
its purpose, though perhaps a woodworking stain isn't the best
solution. Biologists have a number of stains they use for this sort
of thing. You might try your state's extension service.


I have used stains to help clarify the tree rings, but it is only after sanding to 1200 grit that I am able to see the rings. I only use stains if the sanding is not adequate enough which is rarely the case.

But you said you couldn't see the rings because the sanding plugged up
the grain?

For most species I can see the rings despite the saw dust.

I'd think the stain would help with that (again, perhaps not wood
stain).

I used a phloroglucinol dye to distinguish the lignified wood from the non-lignified wood. Still, I need to be able to slice the core to remove the pains of going through all of that sandpaper.

Use Granat. ;-) Seriously, how often do you do this?

The reason I want to cut rather than sand is that it will save time, money, and provide a better image when looking at rings that are only a few cells wide. For those who might be confused here is a pictures similar to what I am trying to achieve: http://www.wsl.ch/medien/news/video_...1/Picture2.png

Yes, that looks like a microtome that someone else was talking about.
I haven't seen one that long.

Easy to duplicate. Take two sticks and place them on either side of the
work to be planed. Somehow (ok, this part isn't so easy) hold the core
steady and run the plane along with the smooth parts of the plane running
on the sticks. A block plane would be ideal, but a good jack plane will
be of some use.

How about a slot routed in a larger board? Maybe with a fence to keep
the plane in a channel so it can (eventually) run on it's
(non-cutting) edges.

Lee Valley has a variety of planes that are well worth looking at, from
the really inexpensive miniature planes to the unbelievably (until you
try it) expensive ones. The most important thing is getting a sharp
iron. If you can sharpen, you're all set. If not, well that's another
thread or 20... I'll just say for a standard plane iron the Work Sharp is
as close to "no experience but nicely sharp" as you can get.

If you actually want to save the slice, that will take a little more
effort.

I think the only problem with this whole idea is that it's a
cross-grain sample and not so easy to plane. Maybe a router or maybe
even a planer (with a slotted boards such as above)?

Even glue the sample into the slot before planing? This would give it
support so it wouldn't come apart. You'd then have a pretty plaque
with the growth rings to hang on the wall. ;-)

This sounds like instructions for planing the end of his "stick", like the end grain of a dowel. Am I thinking correctly?

I think he wants to plane along the length of the stick,

AH, a light dawns. I'd still recommend the same thing, but for a 16" long item, you get the hole
by grooving two boards and fastening 'em around the stick.

Maybe a bead of hotmelt glue or construction adhesive would be better than wax...

I have already made a vice for the core. Any recommendations on the size, price, brand, or angle of the plane?

The intended function of a low-angle block plane is to cut endgrain; it should be good
for the intended task. If you use sacrificial wood jaws, a tight-mouth smooth plane (#4) ought
also to work, if you hold the iron at a slight diagonal to the cut. The bed of the plane ought
to ride on something other than the work, but that's what the wood surround is good for.

It seems that I would need a 13000 grit stone to sharpen the blade which would cost me 150 dollars, totaling to about 250-300 dollars.Any ideas on another method that would involve disposable razor blades?

You don't need that fine of grit to sharpen any average/reasonable quality blade and sharpen it well enough to shave your rod. As for as grit, your local auto parts store has 2000 or 3000 grit sand paper ($5), for honing an already sharpened planer blade. Securing the sand paper to a glass pane, or a scrap piece of smooth granite, will do fine, for honing the blade.

Might want to wet (several - 10 drops of water) the sand paper, when honing..

A grafting technique set the twig in wax use a scapel to slice at an
angle, a back and forth motion is best. Take a few twigs from bushes
trees and practice.

Surgical scalpel, with disposable blades ... Xacto knife in lieu thereof.
