This was a recent collaborative project made at my work in conjunction with a master leather worker from the same building. He was the recipient of my Reifelholz and has supplied me with the leather used on many of my own projects shown on this site. The desk was for a client in Germany.
I was responsible for the under structure, trim and assembly while he made the covering panels. The basic construction was with three mdf torsion box’s, mitre joined with internal hardwood “L” reinforcement brackets and a mitred facing strip applied around the perimeter. The main panels were 1/2” maple veneered PC while the 1/4” ones were BB plywood. Macasser ebony trims it off. A 1” x 1/4” square steel tube is epoxied inside the top over its length.
Parchment is an very, very old material, dating back to about 2500 BCE. Basically it is goat skin which has been flayed, limed to remove hair and then soaked, stretched and dried. To make furniture panels with it the veneered boards are first covered with multiple thin coats of gesso and sanded smooth. Because parchment is mildly translucent, colour may be added to the gesso and thereby tint the overall appearance. The skins are then soaked and stretched over the panels with staples holding them in place on a back bevel. The adhesive most commonly used is rabbit skin glue.
While the skinned panels were still wet I full glue spread and clamped them one at a time onto the torsion box’s with cauls and mdf pressure pads. About a 4 hour curing time. This is done because the drying skin will contract smooth and tight but the panels will warp horribly if left unrestrained.
The wood finish is shellac, oil and wax. Drawers are lacquered BB plywood running on hardwood strips with false fronts. Coved undercuts on the drawer carcase bottoms allow for a pull.
The rear of the desk shows the same as the sitting position with identical false fronts.
Try an inlaid parchment panel on your next box lid or drawer front. It is uncommonly beautiful with a visual texture and feel like no other material.

In looking at the rear of the pictured piece (left side) you may appreciated with me the virtue of tightening the shaper fence before turning on the power feeder. There is nothing like the sound of a rapidly increasing cut, to snap open your eyes and tighten your gut.
