g'day I'm Patrick from douglas-fir design welcome to the router pick Wow a quick look at these flush trimming bits they're really handy reroute a bit it allows you to duplicate a master pattern or a monster piece we've created so if you have one sort of shape these made that you like you can then use this to create exactly same shapes multiple times and similar pieces of timber when you're using a router bit that has a bearing line the purpose of the variants are follow a template or piece these creditor you're happy with to get the exactly the same space on another T now the reason that you might place bearing at the end instead of the base like on these demonstrates with variants is that you want to follow a template that's actually underneath the workpiece that you're working on to demonstrate the way that I use the flush tremendous I decided to create myself you pushed it out of timber first I chose my template out of one that I bought earlier and timber clock and then I cut it out with advanced or as neatly as I can you have to be careful it's a little bit slower I then sanded the whole thing so it feels like the peaks that I want to ultimately end up with secondly I've had a few of these much more roughly on the bandsaw just get it past the time have quite a rough edge but the cut has to be on the outside of that traced one and this is what your ultimate ly going to end up cutting with this is going to be your template to make this work you place your template down first you clamp your large piece the rough cut one on top of that so that the edges just overhang we clamp that whole piece down then you use the flush trimming bit with the bearing on the bottom the bearing is going to be touching that reference piece the whole way around and the blade is going to be in contact with a rougher cut bit just on top and that will give you a perfect duplication right so this little demo I just used on the quarter inch flush trimming bit in my small router little trimming Runner and did a great job create a perfect copy and also in the edge of the radix traders with keep smoother than the edge that I was able to get on the bandsaw a bit of sanding so if I was doing lots and lots of these the initial templates that I used on the bandsaw probably would've ended up being used because the finished credit has a router so much smoother so kind of have a few variety in the flush trimming this the one I just used with the standard variety they're the most economical they have to blaze carbide blades are they come in a quarter or a half inch shank the blades are just directly straight up and down perpendicular to the piece of work and it's perfectly suitable for light work it's a softwood with only 90 mm thick and also currently deep work perfectly to that the next one in the range is their heavy duty flush trimming bit they still have two blades but the blades are regular the net is negative angle what that means is that as a wave comes in contact with the wood it's one part of the plate at a time we just create the smoother cut the shank is also a lot larger which also helps with the smoothness of the cut and you can do much heavier work it's a larger pieces or heavier timber like hard recycled timber and that will be fitting to larger pieces that your nature the third variety are these ultimate flush trimming router bits rather than true blows on the shanks they have three the shank is also 22 mm thick rot the 19th that is just going to be a stronger bit with a smoother cut the blades like last bits are relative negative angles to the helps with the speed leading cut and then finish the exclude miss of the finish most of these relevance come with can come with a barrier at the bottom as well as the top if you want that extra versatility having a bearing on the top of the router bit as well as the bottom just adds to the versatility it's a bit it means you can reference a piece on the bottom of what you can trim or on the top without having to change people add bearings and take the one little push stick I made is just one of the thousands of things you can do with one of these mushroom bit you'll find all kinds of uses for them just use your creativity super handy all-around shop I'll talk on a flush trimming bits are available exclusively from timber cut you can grab them online Kevin columns are you want off the back of that trailer you
