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.

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.
