I’ve been asked to make a built-in cabinet to fit in between a stone fireplace hearth and a wall. I’ve have no problem building the cabinet, but I will need a filler board between the side of the cabinet and the rough-edge stone hearth. I vaguely understand how to do scribe line transfer to match the contours of the stone to the filler piece, but I was wondering if anyone knows of videos or pictures of actually doing it.

I will want to make a right-angled piece that will contour-match vertically from the floor and horizontally to the wall.

Here’s a photo. The cabinet will go to the left. Also, I will probably fill in the gap at the back of the hearth with some mortar before I fit the filler piece.

Anyway, it really just looking for the best way to scribe the contour to the filler piece.

Thanks!

I can’t advise you on the scribing, but I would first use a masonry blade to true up the edge. And then you will have a narrower gap that can be filled with a caulking material that is tinted to match the existing mortar. Or, at least, it will make the scribing easier.

With the “fine-grained” roughness in the hearth surface, I’d use a small compass to transfer the detail of where/how to trim your side panel. Let the compass steel pin trace the hearth surface while the pencil end marks your sdie panel.
The profile could also be obtained with one of those “bed of needles” type devices for transferring contours.

The matching is easier if you back cut the side panel enough so that you only have to shape a thin layer of wood.

Alternatively you could either flush up the hearth edge or make a shallow groove in the surface so the side panel effectively is inserted into the hearth surface (kind of like a rabbet in the hearth surface).
An 4-1/2” angle grinder with an inexpensive diamond blade would do the cut quickly.

Compass for tracing works, then issue is how to contour edge. If contour isn’t excessive a belt sand will make fast work of the job. Band saw, scroll saw or jig saw would be additional choices in descending order.

I would just make it fit as close as possible and find a slate wall trim piece and mortar/adhesive that down. Plenty of sizes and shapes of trim/finish pieces. They also sell tubes of sanded adhesive in every possible color.

Have your say...
