Default Birdsmouth Cutters
Report Post Report This Post!

I recently attended a what was to be a demonstration on Butterfly cutter and Birdsmouth cutters. Curious to see what a birdsmouth cutter was intended for I fronted up to the demo. Unfortunately the demonstrator had been asked the night before to show the cutters and therefore he had little time if any to prepare the demo therefore it was in my mind a flop as people left still not knowing the use of the Birdsmouth Cutters.
We were presented with the cutter (Birdsmouth) actually there were three of them, without any explaination so it got me thinking as to how they were to be used. I spent some time at my computer and drew up the answer. I had never seen them advertized in any catalogue before that day. Has anyone any experience and comment on the use of the cutters. I certainly can see merit in their use

Hi Tom: I have the three birds mouth cutters, and I have used them to construt rounded objects ie; a waste basket out of cherry lumber to match a vanity. The birds mouth shapewere used in building masts for boats, it allows the strips of wood to interlock, and once glued and dry a plane or other cutting/smoothing tool may be used to make it round. The three cutters are for making cylinders using different numbes of of slats, for different circumferences. Hope this helps> Woodnut65

Hi Tom

Just checking to see if we are on the same page ?

If so,I use the Edge Banding bits all the time but I don't use the Butterfly bit because it's a pain to setup.

Thanks for the reply and as I said they had some merit for their use to do exactly what you said you used them for. It was the first time I had seen the cutters the name intriqued me as I had made many Birdsmouths in my time as a carpenter but on roof jointing so I was interested to see the result with a router cutter.
Thanks for your reply and wondering if others have used them.

Not really the same page Bob these were used to construct masts as explained below but they were new to me


Never having used the Buterfly Bit either I do have to agree it is a pain to set up at least the demonstrator thought the same with the results he was getting

Is there such a thing as a double-dovetail bit
I would not like to say No to this question as I was surprized to see the Birdsmouth

Your drawing or sketch is right on!!!

The birds-mouth bit comes in three sizes for either a 6, 8, 12 or 16 sided cylinder or cone and can be used to make columns, planters, bowls or elaborate corner details.

I have never had the opportunity to use a birds-mouth but have seen them in the local Lee Valley store and catalogue.

Here are two links, you may find interesting, one being Lee Valley and the other a shop tip from Wood magazine for your information.

Hope this helps those who may be interested in using these bits.

Also called Multi-Sided Glue Joint Bits

http://www.mlcswoodworking.com/shops...ed_glue_anchor

Great Links Ric

I ordered a set from MLCS tonight because of the 3rd. snapshot below
Think out side of the box ,it's great way to make a corner joint.
Can't wait to give it a try out...and with a 1/8" x 3/8" spline it would be a strong joint.

Thanks Labric and Bob for including the pics you say you are never too old to learn so I certainly did learn something since last weekend and you are right we must think outside the square. I suppose that is what I have been trying to get others to do when it comes to using the template guides. Think outside the Square and you will find greater use for the template guides That is why I think we should have a topic on Template guides I could fill a book on how they are used actually I have. When I was conducting router workshops I began introducing the acccessories like the side fence attachment and demonstrated how it was used. Not a great deal you can do with the attachment you may well ask! well I use it for my circle cutting jig my elliptical cutting jig it is great for a router support I produced when routing the edges.

There was at one time a trimming accessory which has now been removed from most router accessories since the introduction to the cutters with bearings.

The template guide was the other accessory supplied at the time of purchase, and this was the remainder of my three hour instruction. How to get more from your router with the aid of the template guides. I introduced a variety of guides and showed them how they were used. Thinking outside the square was important and that is what I have been doing when it came to using template guides for a number of years. I am still convinced that there are router enthusiasts who still do not use the guides

Hi Tom

I know I'm not the sharpest pencil in the box that said, I think a topic on Template Guides would be great BUT I would suggest you bring your tutorials down just a bit you are to smart and you know way to much and your URLs/post show that and it's hard for me to read and follow some of them , you need to make it simple.

PLEASE take this the right way Tom

Bj
