There is a hinge at each corner, and one each in the middle of the side rails.Sgt42RHR Tenons_on_folding_side_rails_at_each_corner_and_middle.JPGTenons on folding side rails at each corner and middle142 viewsHere is a good shot of the curved tenons used at each corner and at the middle of the side rails. I made a metal template for marking out the shape which is a segment of a 1 1/2" diameter circle. I sawed off the excess waste, pared more of the waste away, and then finished with a shoulder plane. I sloshed some mineral spirits on before I snapped the picture to see what the grain looked like.Sgt42RHR Offset_mortises_in_head_and_foot_corner_to_receive_folding_side_rail_tenons.JPGOffset mortises in head and foot corner to receive folding side rail tenons198 viewsIn the head of the bed the mortises for the curved tenons lean 1/8" to the right and in the foot of the bed they lean 1/8" to the left. This will allow the folding side rails to scissor over and under each other as they fold.Sgt42RHR Washington_bed_Conservators_interpretation_of_stretcher_bar[1].jpgRecreated stretcher bar for Washington bed131 viewsThe stretcher bar (spreader bar?) was missing from the original Washington bed, here is the replacement the conservator made; I'll probably do something just like this in shape. If you look hard on the left rail, you can make out the mortise with a open sloped side to allow the bar to slide in. On the other side it's a regular mortise.Sgt42RHR Washington_Bed_Conservator_photo_of_partially_folded_bed[1].jpgHow the bed folds and unfolds314 viewsThe conservator sent me this photo which provides an excellent view of the relationship of the parts to the whole. Captured here in the midst of a fold/unfold you can see the necessary scissoring action of the side rails, the rounded stub tenons at the corners and in the middle of the side rails, and the folded legs and posts. My next challenge will be to cut the mortises in the center ends of the side rails. I can also see in this detail that the center side rail hinges are mortised into the side rails Sgt42RHR Washingtons_folding_field_bedstead_by_Dick_Toone~0.jpgShowing the linen canvas foundation171 viewsBecause there will be some sag in the linen canvas foundation (though less than in cotton canvas), the spreader bar underneath the bed must be curved so that the sleeper will not feel the bar. You can see Dick Toone's intrepretation of the curved spreader bar here.Sgt42RHR Ramped_mortise_detail.jpgDrawing detail of mortises for spreader bar186 viewsHere are the details of what I've been referring to as a 'ramped' mortise to receive the tenons in the spreader bar that will go under the bed's fabric foundation. The purpose of the spreader bar is to keep the side rails from closing inward.Sgt42RHR campbed10.jpgFolding bed forged iron hardware146 viewsHere are the drawings of the forged hinges and hook & eye arrangements on the Washington bed. I had them duplicated exactly; they are not lightweight.Sgt42RHR Washington_Bed_Conservator_photo_of_side_rail_center_hinge[1].jpgProblems with the side rail center hinge139 viewsThis conservator photo shows one of the side rails at the center hinge. You can see that the hinge mortise is broken out on one side, probably as a result of too much vertical movement. Perhaps this is why a center leg was added to the bed at some point in its life.Sgt42RHR Side_rail_mortise_and_tenon_fit_perfectly.JPGSide rail mortise and tenon fit perfectly!118 viewsAfter having drilled out the waste with a cetner bit, pared the sides to the gage line, the two center ends of the folding side rails fit perfectly. Ready for the hinges now!Sgt42RHR End_grain_mortise_completed.JPGEnd grain mortise completed160 viewsIt was easy to pare out the remaining waste left by the center bit. The bottom is nice and smooth as well.Sgt42RHR 15 files on 2 page(s) 1 2 Powered by Coppermine Photo Gallery and JoomBla!
