| Post subject: | First Radial rosette. |
Though I'd try a radial rosette for the first time. Client said he had some Plum wood and could I use it for the rosette. Turned out to be a few thickish branches from a local tree growing in a wall, cut down by the local Laird which said clients Wife had aquired. One log he'd tried to help (bless) by drying it out, putting it next to the wood stove for a month or so (split everywhere of course) Another other chunk he brought was rotten in the middle (lying in a field for a several years), but I managed to salvage enough for this. I do like the wood, subtle, with pink/lavender/purple hues in it. I still have to level everything, just waiting for the glue to dry. |

That looks really nice, Colin! Should have some pop when the finish goes on! I did a book matched end grain olive wood, for my #2 in progress. Alex |

No worries Alex, nothing proprietary, got the general procedure from OLF, Burton LeGeyt and Todd Stock IIRC. Made some wedges at 2mm thick on a small shooting board set at 22.5 degrees and superglued (thin CA) them to a 0.8 mm (1/32") square ply backing board double taped to a formica laminate board, cleaning off any excess CA with acetone. Adjusted the last 2 wedges at the top for any cumulative error in the angles. Then thicknessed the assembly on a 10-20 drum sander to 1.8mm and cut the rosette out with a wells-carol circle cutter. (target thickness for the top was 3.0mm) Removed carefully with Naptha (messy!) and cleaned up. Glued this into a channel cut in the soundboard (thickness set with the excess rosette material), left overnight to dry. Channels for the purfling were cut with a bit the same size as the purfling. The back edges of the purfling were bevelled, it was formed to diameter in steam, then tapped in with a small hammer. Excess purfling levelled with a block plane, dried overnight, soundboard run through the 10-20 to level and clean-up, final thicknessing done on the back. All bits used were downcut spirals (1/4" and 1.3mm), TB glue was used on the soundboard channels, sealed with 1lb cut shellac. |
