This aluminum miter box is great for rough 45 and 90 degree cuts. No matter what miter box you have there will always be inaccuracies when cut. This is more so from saw movement than improper angle placement. These inaccuracies are easily cleaned up with a shooting board or simply ignored if + or - .5 degrees is acceptable for your project. My project is picture frames. So, four miter joints can add up to a lot of error and gaps are much more noticeable in picture frames compared to say, baseboard molding in a bedroom. The miter box I received has two 45 degree cutting slots. One is quite accurate and I can rely on to produce a proper 45 degree angle + or - .5 degrees or so. Two or 3 passes on my shooting board plane and I am good to go. The other 45 degree slot is much less accurate. Im guessing it may even be off a degree or two. Again though, I can use it I just need to spend more time finishing it on my shooting board. The 90 degree slot works very accurately and is also easily cleaned up on a shooting board. The miter box opening to put material in to cut is just under 3 inches wide (~1/32nd inch shy on mine) and 2 1/4 inches tall. It is around 9 3/4 inches long. The width of the cutting slots is pretty small, but it does fit a standard miter box saw. It also fits most any razor saw. This miter box has a clamp part that can be screwed down into the work being cut. The clamp end that will touch the work is around 1/2"x5/8". It is kind of small so I usually put a small piece of 1/4" softwood between the clamp and the work to prevent damaging the work. Another thing absolutely essential to using this miter box effectively is to put scrap wood on the bottom of the box. This prevents you from hitting the aluminum when you saw through the work. I have attached a picture showing my setup. I have also attached a picture that shows the capabilities of the accurate 45 degree slot I have. Pros: *One of the 45 degree slots and the 90 degree slots works well *Small cutting slots that provide an accurate cut *Built in clamp that is very useful Cons: *One of the 45 degree cutting slots is very inaccurate(-1/2 star) Additional Considerations: This box does NOT come with a saw. You will need to get one. I recommend a <link jap saw> Overall: 4.5/5 stars (>=.5 rounds up, <.5 rounds down) => 5 stars If you have any further questions regarding the product in my review please leave a comment below and I will get back to you as soon as possible.
