    Default Butterfly/Bowtie jig problems

    I bought a solid brass inlay kit some years ago and promptly broke the 1/8" cutter. Now I have a couple of jobs that need multiple butterflies and so bought the carbatec specified replacement router bit to use with a Jasper Butterfly Template to speed things up a bit. Bugger! Cuts the hole too big! Got around the problem by wrapping a couple of rounds of gaffer tape on the brass collar. Works , but ugly and probably prone to disaster. What do you reckon? Undersize replacement router bit? Turn a new collar? Other options?

    If the hole is too big, your bit is too big by the thickness of the tape. Could it be that you're using a 1/8" bit when you should be using a 3mm bit?

    Got hold of some verniers and checked the new bit, 1/8" alright, and the original kit said 1/8" too, so although that's a good suggestion I don't think that's it.
    The original inlay kit does not have a brand as such but was distributed by Harbour Freight. I wonder if anyone else uses the same? Perhaps I could compare dimensions of the collar to see if there is any variance?

    If there is any play in the plunge guide posts, it will create a gap in joinery because the arbor is moving in relation to the base plate. Because of the natural way we use a router hand held, the gap due to guide post play will be greater in one direction than the other. My triton routers developed a fair amount of play in the guide posts and every time I tried to use guide bushing for snug fitting joinery, it ended up loose and I had to fudge it with a hammer.

    Whilst this may not be the issue here ,there can be issues with run-out on the shaft.
    Buying a router with multiple collet usage ,its imperitive to also check the run-out on the shaft if the router using the large bit collet gets some hard usage either hand held or in a bench before reverting to the smaller collet.
    It's a constant that is readily overlooked in routing.The internal shaft bearings have to be of a quality to withstand the forces implied ,this may or may not be consistent with routers that are marketed for the DIY intended users.

    This is what most people may find happens with most users of this combination inlay kit especially if there is a large cut-out to be made. This is the time to consider using an alternative method of cutting recesses and inserts. By selecting a suitable template guide and cutter to rout the insert then with a change of Template guide and cutter combination to rout the insert

    It is all about understanding how template guides and cutter's can be used to produce a greater number of routing projects. If you have any questions I may be able to give you advice.

    Sorry Tom, I'm confused. I didn't think the template would be a problem too. Can you recommend an inlay kit that does not have the same problem?

    Yes Lappa I had a look at what there is to offer and looking at the largest template is what I was referring to it's a fair bit to get cut with such a small cutter especially if a hardwood is to be used. My suggestion is to make your own template to suit the choice of template guide/cutter combinations that can be used to complete the process.

    My suggestion is to produce your own template to accommodate the template guide/cutter combination to complete the process.

    To follow on to my last post. I need to know what template guides you have for your router. Regarding the diameter of each so that I can suggest the various combinations necessary to complete any inlay problem you may have.

    I'm not sure if you have any template guides or if you have used them or not.

    I had already read your postings and that did not answer my question
