When carving a new bridge, the heart wing is very delicate and can easily break... quite annoying when that happens Surprised

Question... what technique do you use to ensure the delicate heart wing does not break? Do you do it first or last?

Cheers, ....Mat.

I was taught by ( hans nebel ) to make up a bunch of bridges ahead of time, put a drop of super glue on the wings and heart, and let hang up in your shop. this stiffens the weak parts . and use a sharp small knife .

Some people cut that thing off anyway. The usual (I think) recommendation is to trim the delicate parts first so that there is less chance of breaking them off when you plane the faces. I use a 3mm sharp chisel to skim the points off, and always take thin cuts. I've broken two or three and glued them back.

Bridge trimming (in this avenue) is mostly an aesthetic consideration. The bridge, in this aspect of construction, is mainly an aesthetic thing. The aspects of trimming and the aesthetic " looks" of the bridge - are mainly considered in a contextual aspect.
Sound versus - anything else ...

The workability of such a thing, (a bridge design, and construction ) is merely incidental to its appearance. If it works well - then fine. I not, then well - it is considered inappropriate,

Good luck with this aspect, as it will render its own verdict.

I use a curved knife and slice at the heart, some brands break more easily than others in my experience.

Second that. According to my experience, the Tellers can withstand much worse torture than Auberts, for example, if we are talking about - say - middle level bridges.

Here is what I finally figured out to do.... the jig has wood pins so that I am always cutting against something firm.... works well.
Cheers, Mat
