Router Bit Kick

On a bit of a kick at the moment, each router bit is like a new tool because they work so differently one from another – some do edging, some shaping, some copying, rebating etc etc.  And there are so many interesting ones out there 🙂

Some that have recently caught my attention, and will be covered individually shortly are some Flai bits, to see how they perform compared to the brands I am currently useful.

Computer Depiction of a Flai Router Bit

I haven’t tried the Flai bits yet – I have a couple, and will be interested to see if they, and particularly their edges perform as well as their saw blades.

Double Rebate

This bit is one of the new ones in the Carbatec range – a double rebating bit.  It is used for picture framing, as it cuts a rebate for the glass (either 3mm or 6mm depending on which of the 2 you choose), and a second, wider rebate for the backing board.

One very useful addition for bearing guided bits is a set of bearings of different sizes.  This allows fine-tuning of how the bits work, increasing their versatility even further.

You can buy a set of bearings – there is a set in CMTs range for example

791-703-00 Bearing Set

But for the price, there is a better way: a rebate bit that includes a set of bearings.  The CMT bearing set is $77, for $22 more you get the full rebate set.

However, what really caught my eye (when I was shown it by a friend) is

The Grand Rabbet Set

835-503-11 Grand Rabbet Set

Now it may not look as impressive in the photo here, but that is in part because you don’t have a scale reference.  The rebate (or rabbet in American) bit itself is 2″ in diameter.  What’s more, those are not bearings in the box – they are a kind of sleeve.  And the concept is significantly cool.  Instead of having a whole set of actual bearings in the range of sizes seen here (which would be very expensive), these are solid, machined sleeves that fit a bearing top and bottom so they run exceptionally well. The bearings themselves are replaceable (if it ever is needed) at a comparatively low cost.

With the cutter at 50.8mm (2″), there is also a sleeve that is the same diameter, turning the rabbeting bit into the largest flush-trim bit/pattern copying bit that I have ever come across.

Looking forward to getting to try the kit out – bring on the rabbet stew!

Trimming to Perfection

During the Breaking Edges article where I spoke about using the FastCap Fast Break XL to take the final sharp edge off where an edge banding has been applied and trimmed to size.  During that article, I briefly showed how I used a sharp blade to trim the laminate to size. It isn’t the best technique (especially given the occasional time that I perform the task) that unless you have a particularly well trained hand, you can end up with a less-than-perfect edge. (Not bad, not perfect).

Not surprisingly, there is a better way, and FastCap (via Professional Woodworkers Supplies) has that solution.

The problem again, is once a board (melamine, or other veneered board) is cut, the core is exposed and that needs to be covered.  It is typically done with a roll of like material, with a heat-activated glue back.  This roll is wider than the width of the board, and therefore needs to be trimmed accurately.

Overlapping Attached Edging (upside down)

Step one is removing the overhanging end, and that is done with the FastCap Flush Cut pliers.

No point explaining what they do.  I think you can figure that out already!  Another lame parody of a movie title “Flush-Trim is, as Flush-Trim Does” (ok, too lame.  Think Forrest Gump)

Trimmed end

Step two is to trim the sides.  There are different techniques used to achieve that. There is “The Blade” which I have utilised in the past. Flush trim bits, mounted in a trim router is a very commonly utilised method by professional shops. And then there are edge trimmers.  These typically have two blades mounted in a spring-loaded handgrip to be run down the entire length of the board.

But again, there is a better (or in this case, a refined) way.

FastCap have come up with a Quad Trimmer.  This isn’t a Gillette solution (adding more and more blades to a razor, supposedly making it better and better), but instead it has a blade that cuts in either direction, and can be flipped over providing another two blades.

These blades are replaceable, and the Quad Trimmer comes in either in a carbon steel (blue) variety, or a tungsten carbide (red) one (called the Quad Pro).

FastCap Quad Trimmer (Pro)

I am particularly impressed with the simplicity of design.  Both sides of this unit are identical (and identical between the blue and red varieties), which makes the manufacturing much cheaper.  Furthermore, other than the fact that the sides squeeze together, there are no moving parts.  No springs.  Instead there are two pistons, with o-rings at the end (and some lubricant – presumably petroleum or silicon based – to aid with the seal)

Separated sides

The internals look a bit complicated, but it makes more sense in 3D.  There are two narrow tracks, which allows the overhanging edgebanding to pass through before hitting the blade.  There are a couple of full-length shoulders which supports the tool as it runs along the edge.

Performing a Trim

To use the tool, simply grip it, and run it along the edge, in either direction.  Openings in the side allows the waste to peel away freely.  An interesting fact about the blades is the carbon steel blade lasts 5 times longer than regular steel blades. The tungsten carbide blades last 5 times longer than the carbon steel (and therefore 25 times longer than regular steel).  That may help in the decision whether to get the Quad, or the Quad Pro.  However, as is true with other tungsten carbide tipped tools, TCT is not chosen because it can produce the sharpest edge, just one that is significantly more durable.  A steel blade (carbon or otherwise) is in fact sharper than tungsten carbide, and I noticed this when trying out both varieties.  The Pro certainly did the job as neatly as the standard model (and will continue doing so for a lot longer than the blue version can hope to achieve), however there was a noticeable difference (say roughly 10%) in how easy the blade cut the material.  Decisions, decision.

The Quad Trimmer (either variety) can trim boards from 1/2″ to 1 1/4″ thickness.  Neither have any springs, or even (as can be seen above) require a fiddly method to fit the blades.  Both cut in either direction, and with 4 cutters means they last a lot longer between sharpenings, and blade replacements

Precision Trimming

Combining these tools with the Fast Break XL, I guess the next laminate job I do will have an even better finish, and even less occasional damage I get when using the blade I have in the past.
