Good exersize too :-)
Does what I'd hoped. I've had to devise ways to hold it in place when working with harder woods.

The Miter Trimmer worked great. I will have to make a supplemental jig to support long pieces but it works great

Perfect joints
Remember, this isn't for cutting a piece to size. It's for fine tuning your cuts. It slices very fine pieces off of a cut piece. If you want it to cut a piece of oak that is 2" thick, it's not the tool. Use your saw for that. This makes the final cut incredibly smooth and perfect. You can slice as fine as you need to get a perfect fit. Highly recommend this trimmer if you want to make perfect picture frames.

Love working with the Miter Trimmer
I wish I would have bought one of these 35 year ago.
I had trouble making tight miter jonits, but with the miter trimmer
it was considablely easier. I never made miters this tight before.
All finish carpenters should be using it. Makes job much easier and faster.

A must for precise frames
This tool was originally produced in the 1880s. The factory produces these for many companies, but they are all the same. The key is to pre cut the miters about 1/16th over, then use the trimmer to take off about 1/32nc. I mounted mine on a sheet of ply with a 1/1 1/2 wooden piece on one end that fits into my wood vise. That holds it very steady and helps make for perfect cuts. I tried all kinds of jigs and could not get a perfect miter. The slightest blade deflection will ruin the cut. You will find one of these in every frame shop because it is the only guaranteed way to get a perfect 45. Just don't try to cut off very much. The Rockler price is good on sale. Once you use it you'll wonder why you waited so long to get it. My wife is a budding artist, which automatically makes me a frame maker. Make sure your stock is flat or you will have trouble clamping and gluing. Splines in the corners make for a much stronger frame. Don't sand finer than 150 grit if you want the stain to penetrate properly. Pre finish before you cut the stock because glue squeeze out will spoil the corners if you finish after, unless you use paint.

Use it for what it was made for!
As a Journeyman cabinetmaker You need to know that this cutter is for sliver cutting NOT the hole raw cut! that's what the miter saw is for. This tool is to fine tuning your miter.

Woodworking Experience:
I just finished installing several hundred linear feet of standing cherry molding in my home. I purchased this about 1/3 of the way through the job- and what a difference it made. As others have noted, it has only 90 and 45 degree fence positions. Having this same concept with high-precision fence adjustment would be much nicer and, perhaps, prohibitively more expensive. However...

Using this tool to shave extremely thin shavings- to the point of translucence, is what it's all about. This tool is designed to be introduced into the process after getting the pieces as close to correct as possible with the miter saw. Placing one, or more, business cards between the stock and fence, or even under one edge, provides sub-degree precision just not possible any other way. I've heard professionals rave about these machines and was very excited to finally find one. After a very short learning curve, this has allowed me to consistently produce the absolutely tight miter joints I have strived many years for, and yet rarely attained.

I have used one of these years ago and it always trued up any miter joint. I am doing a variety of projects and want to have better miter joints

I need to make a lot picture frames. I've been using a table saw and jigs... but I used one of these years ago, it made great easily cut miters, so I thought I would get one. They are fantastic for cutting and trimming perfect miters.

Daryl S on Apr 20, 2015
I had one in the past, it did a good job other then the 45 degree angle did not stay in place until I drilled holes for it. I am hoping there has been some changes so it will keep the angle when cutting 3 1/4" trim without moving

Can I buy a handle for the Miter Trimmer ?
Butch on Oct 27, 2015
Where is this tool made/manufactured?
A shopper on Jun 18, 2015
BEST ANSWER: Says made in Taiwan on the box.
Can this cut/trim a 1 x 2 (3/4" x 1.5") piece of oak?
Wood Guy on Apr 16, 2016
BEST ANSWER: No problem. This tool is designed for such tasks. Keep in mind, this is a trimmer. It is prudent to take several paper-thin passes as opposed to trimming to your mark on the first attempt. I have trimmed pieces up to
3 1/2 x 2 with ease.
One thing I would point out is to keep the trimmer oiled with a light oil when stored, or make sure it is stored in a dry place.
Trim a scrap of wood to take off the oil the first time you use it for the next project if oil on your trimmed piece is and issue. This is a tool that makes me wonder how I got along without it.
It is spendy but worth it if you demand precision and don't want to waste good wood.
how many cuts on average per set of blades?
gerald m on Oct 16, 2015
BEST ANSWER: Gerald, I trimmed an 1800 sg ft basement remodel and blades are still in good shape. this is a trimmer for very paper thin cuts. if you try and cut bigger chunks it won't work and will dull out the blades. hopes this helps.
What is the largest piece of wood this can handle?
Dave307 on Dec 30, 2015
BEST ANSWER: Because it cuts on the diagonal, the width of the board you can trim depends on its thickness. a 3/4" thick board can be between 5 and 5 1/2 " in width. A 1 1/2" thick board has a max width of approx. 3". This is all for a 45 degree trim. Hope it helps.
What do you use for blade guards when not using?
James F on Dec 30, 2017
BEST ANSWER: Are you guarding the blades from being knocked? ... or are you guarding your fingers from the blades? In either case, I just move the miter trimmer off my work table and onto a nearby shelf. Better to keep it mobile, and occasionally apply a trace of machine oil.
Will it cut molding 6 inches height??
Joe M on Dec 1, 2016
BEST ANSWER: If you are talking about baseboard around the bottom of a wall - no max height is around 3 1/2 " If it is picture frame moulding laying flat - yes you can cut a 45 degree with it laying flat. Hope this helps
How can I order replacement parts. I need the Spring (17 in drawing). Does Rockler handle parts or do I have to deal with a overseas dealer?

Can anyone provide a link to a video that shows the miter trimmer in action? I would love to see it.
Vivian A on Jan 11, 2017
BEST ANSWER: I don't know about a video but the trimmer works beautifully. The secret is to sneak up on the cut and take very thin (very thin) slices. Be very careful handling the unit thise blades are very sharp
