Great Tool
This is a great tool for sneaking up on a good fit and the sharp blades make taking a "hair" off of molding a breeze.

Broke the Gear - but that's OK - it's not expensive to replace
I have used this tool for at least 10 years with great success, makings thousands of perfect miter cuts. Unfortunately the "gear" (#12 on the parts list) that moves the miter blades in conjunction with the handle broke (the gear snapped in 2 pieces). I went ahead and ordered a new miter trimmer to replace my existing unit, but was curious if I could replace just the gear and repair the older unit. I called Rocker Customer support and they did not offer the gear. Turns out Grizzly Industrial does and it's only $4 + shipping. At that price, I ordered two gears. I thought it wasa Rocker specific tool. It's not. Other vendors carry it and carry the parts to service them as well.

Worth every penny
Like most people I had trouble getting all 4 corners of a picture frame square and closed. This trimmer makes the miters perfect every time, you just have to remember to only shave very thin amounts at a time. My first cuts were just on 2 pieces of scrap birch trim. I cut the miters on my miter saw and then trimmed both miters with this tool. When I put them together the seam disappeared. I then added a little glue and put together with just a little pressure between fingers and joint was so tight no further clamping was needed. I have since used several times when adding trim around a banquette and the were perfect. Should have done this years ago.

Works well; performs as advertised
Performs the job very well. Precision cuts are very accurate. Heavy base and razor sharp knives are what you want from a quality tool. Does a great job on 45 and 90 degree angles. It would be nice if there were more stops drilled into the base to allow more angles (such as 67.5) for making other types of frames (such as octagonal)

Scary sharp and very effective
Used with care this is an awesome trimmer and lives up to the expectations set by the original Lion trimmer. Take a thin slice and you can get a perfect bevel on even the hardest of woods.

Great tool
I use this in piano keytop replacement to remove the old keyfronts . I find the precision and razor sharp blade make a precise cut every time and save up to an hour on almost every job.

Excellent tool
Excellent end grain shavings. Make sure to take small shavings since larger shaving will move the workpiece inwards the blade.
I really like the design and heavy construction of the entire tool.

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

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

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?
Donald C on Nov 23, 2017
BEST ANSWER: Donald I️ have no idea.
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
