Making a cylindrical object more straight

Hi I have a art object made out of wood (obviously) shaped almost like a cylinder. It's about 36 cm tall and it's diameter is about 6 cm. The wood itself is extremly hard and dark (unfortunately I don't know what kind of wood it is, but I think it's from a root). Now, the problem with this object is that I want it to be able to stand straight on a flat surface, but the bottom is a bit tilted, so the whole object is "sloped" (it looks kind of like The Leaning Tower of Pisa when it's standing). I want to correct this, i.e. make the bottom straight, so that the whole object is standing straight. Now, since it's a art object, I don't want to put in a machine lathe or something, because I'm afraid it might be damaged then. So my question is how would you suggest making the object the way I want it. I.e. what kind of tools would you suggest to use and how - I'm especially wondering how to make it exactly straight - i.e. 90 degrees in relation to the cylinder height. Thanks!

A disk sander would work nicely. Just lay the piece on its side and gently push into the disk. you have quite a bit of control with a disk sander.

A STATIONARY belt sander would also work but just a tad riskier. If you don't grip the piece just right it could get ripped from your hand and flung across the room. A hand held belt sander in a vice or other steadying device would also work but raise the risk factor by 100.

Instead of straight I think you mean to say make the base square to the sides.

Tony's idea of a disk sander is good. Most disc sanders have a slot for a miter gauge. I think you would need to use this gauge.

The other possibility would be to cut it with a power miter saw. Or if you hand a hand saw miter box big enough that would also work.

Disk sander sounds like a good idea. I guess it should not be too hard making the base orthogonal to the sides just by hand and eyesight, without any special tools.

Yes, it should not be. I do it all the time.

By disk sander I'm assuming you mean a belt/disk bench/stand type sander like this. If one isn't handy, hand tools work well. One of my most used hand sander tools is an easy shop made block sander made from hand held belt sander belts. I make them for 3"x21" and 3"x24" belts. Just between those two sizes there are many choices for belt types and grits. They look like this...

That's a bit of a contradiction. Either it is a cylinder or it is not.
If it is a cylinder there wouldn't be any problem to get the bottom square to the sides using the above mentioned methods.

If it's not cylindrical then you need to get the bottom square to the center of the object. To achive that you may have to make som kind of jig to hold it in the right position before you get it to the disc sander or miter saw.

table saw or chop saw, a miter blade, a couple layers of blue tape wrapped tightly around the end to be cut with the same around the other end to make it lie straight.

And If I understood your efforts at describing the geometry you are hoping to achieve the proper way to say it is " Squaring" You want to square the end of the cylinder.

Hey~!!! It's a hobby~!! It's not supposed to make sense.
