by DKP

W13 EASTLAKE SOFABED 22w13-eastlake-sofabed-89 This is the third post in a series on this project.  This post continues from the previous post: East Lake Sofa-Bed Upholstery #2A: Repair.  To begin at the beginning return to Eastlake Sofa-Bed Upholstery Conservation #1: Excavation.

The front arm panels were repaired, beginning with disassembly.  Note the broken structural back panel.

W13 4 FXSB REPARATION 37 W13 4 FXSB REPARATION 38 W13 4 FXSB REPARATION 39New structural back panels for both front arm panels were created.  The location of the new hole in the new pack support panel to the original front arm panel was marked, drilled, and new dowels were secured using warm hide glue.

W13 4 FXSB REPARATION 45W13 4 FXSB REPARATION 46 W13 4 FXSB REPARATION 47After curing, screw holes are readied, and new brass screws secure the arm panel pieces together.  Both arm and leg panels are repaired, and the reassembly continues.

W13 4 FXSB REPARATION 65W13 4 FXSB REPARATION 57The seat frame, previous created (East Lake Sofa-Bed Upholstery #2A: Repair), was finally assembled.  As it was assembled, with new corner blocks, it was screwed, glued with warm hide glue, and leveled flat.

W13 4 FXSB REPARATION 66 W13 4 FXSB REPARATION 67 W13 4 FXSB REPARATION 68 W13 4 FXSB REPARATION 69 The arm panel bases were blocked to the new frame for strength.  New mortice and tenons were secured using hide glue onto the seat frame.

W13 4 FXSB REPARATION 75 W13 4 FXSB REPARATION 76 W13 4 FXSB REPARATION 77Leg and arms were glued and screwed, and the entire arm-seat is elaborately clamped to cure square, not torqued.

W13 4 FXSB REPARATION 78W13 4 FXSB REPARATION 79W13 4 FXSB REPARATION 80 The back was reassembled in the same basic manner, conserved holes, mortice and tenons cleaned and made anew as necessary, and the reassembled using warm hide glue.  After reassembly it was attached to the seat frame with the hinges.

W13 4 FXSB REPARATION 82W13 4 FXSB REPARATION 81The bottom of the armrest was assembled next.  The bottom bed frame/armrest was reset properly with Mitchell’s expertise and calculations.  Originally it was set at an angle (simply sloppy, not intentional) which caused the piece to wear.

W13 4 FXSB REPARATION 83 W13 4 FXSB REPARATION 84 W13 4 FXSB REPARATION 85 The hinge which holds the arm-seat must be placed so that the front apron can bend and move as the sofa-bed is deployed and returned to a sofa seat.

Hinge holes were conserved as shown in the leg reparation.

The mattress was not engineered properly to allow for the mattress to move onto the frame.  Mitchell added new tack strips to support the mattress properly, assuming that the sofa-bed will occasionally be used as a sleepover for grandchildren!
