Ok, so recently I have really been struggling with mitred joints. Particularly the long ones that you can cut with a 45 degree bit on a router….
I try cutting them with a mitre box, they don’t fit right, so I try building a shooting board and fail at that miserabley (Probably because I was trying to use a jack plane that doesnt have enough side to stay really square.) I tried cutting through the joint with a hand saw and fail at that too. I need a lot more practice with my hand tools.

That being said, I’ve got a couple of projects I’m trying to get done by a particular date and while I intend to keep practicing, I need to move things forward, and I was considering adding a power tool to the stable to help out. What I can’t decide, though, is which one would be better for the task, a sliding compound mitre saw, or a stationary sander? I don’t mind upgrade side table rsupports for the saw or a better table for the sander, i’m just wondering which one would be better? are compound mitre saws usually true enough, or should I keep making the cuts by hand and use a sander to true them?

I would definitely go with a miter saw. They can be adjusted for trueness, and should give you excellent results. I build a lot of small boxes, and do all my miters on an inexpensive Ridgid miter saw.

Each tool has its place. I have the dewalt 718 miter saw and was suppressed how accurate it is. You still have to have precision tools to check or perform the alignment. You will want to extend the saw to support longer pieces and a measuring system to get repeated cuts of the same length.

When I need to trim a smig off of a piece I will use a stationary belt sander. I use a precision triangle or 45 degree square to set a scrap piece on the sanders table and then I can gently touch the wood to alter it’s angle or remove a smig at at time.

Are your pieces coming up at different lengths causing the miter not to be exact or is it the angle?

Do you have a table saw? A very good miter gauge, such as the ones made by Incra, can work wonders. That said, there is always a place for a good(!) miter saw in the shop, especially if you plan on doing any trim work at your house. When I first started out, I had a Ryobi sliding compound miter saw (SCMS) that wasn’t worth a dime. I finally upgraded to a Dewalt miter saw with a 12” blade and the difference is night and day.

A table saw and a sled works best for me. Just make sure you have a way to check your blade angle. Never rely on the gauges on the saw. Just because it was correct once, doesn’t mean it will be forever.

I find a good sled with a good clamping mechanism for your piece is awesome. You don’t have to worry about the piece jumping a bit when it first makes contact with the blade. You can also set stops and repeat your cuts accurately. A miter saw does work well, but I don’t have the space to dedicate a miter saw station incorporated with stops and hold downs

I, too, vote for the mitre saw over the sander.

Having said that, though, I think you’d be better off (and spend less money) going back to the shooting board. A low-angle (bevel up) jack plane would do the job. You can pick up the Stanley right now (Amazon) for around $126. A Veritas will cost around $225, and a Lie-Nielsen around $240.

I’d go for the Stanley. You can invest considerably more in a sliding mitre saw but, to get the quality (accuracy and stability) you would need to cut consistently good mitres, you’ll be spending a minimum of $500. An extremely accurate shooting board can be, basically, free to make. That and a $125 low-angle plane should give you good joints.

I agree with Brandon, the table saw does beautiful miters with miter gauges and sleds of various kinds. They are also easily and quickly set up. The table saw will also do many other nice things.

Jesse brought up an important point. If you are trying to make something four-sided, like a box or a picture frame, having your opposing sides identical in length is just as important as the accuracy of your miters.

If your boards aren’t flat, miters won’t turn out right.

I’d say miter saw if you don’t have one. Next to the tablesaw, it is one of the most versatile tools you can have.

Many miter saws are not very accurate and can be hard to adjust for a true 45 degree cut, but I would select a miter saw over the sander. If It were me I would make a jig and do your cuts on the table saw.

Yeah, the problem is a gappy joint. I’m positive that the boards are the same length, when stacked together I almost couldn’t feel the difference on the ends. That was of course before my botched attempt to shoot them with an inappropriate plane.
I’m trying to avoid going the a table saw route if I can, I have several reasons that I won’t go in to here.
The plane does sound like a good option and I would probably enjoy that solution, but I think I may pick that up for projects I want to spend more time on and go ahead and get the saw for things that I just need to knock out.
Thanks for the advice guys.

Miter cuts always need tweaking to close perfectly. No matter how much you fiddle your set up, there will always be some error, albeit very small with a good set up. One trick I use on the miter saw is to use a very thin shim(s) to shift the opposite end of the board to the end being cut. A guy can make super small adjustments to the angle this way, far finer than that by trying to tweak the setting on the saw itself.

I make all my miters on a table saw.
I have an Incra Sled and an Osbourne miter gauge.
I find them both to be extremely accurate.

a sled on the tables saw is usually more accurate than the miter saw. if you have a decent table saw take the time to built a sled for it. There are dozens on the site that you can look at.
