Problems about screwing of logs will always be the focus of attention as main wind plug and corresponding notch unfortunately can be connected only freely or by 2-6mm space between them. Thus accuracy to main plug requires wrapping of insulation materials around joints during assemble. Also carpenters will never handle such a mortise and tenon system and therefore cone-shaped surfaces must have insulation materials always pressed between. Somewhere joints will be pressed by insulation materials too tight and could trouble compaction of house. So problem is always tied with next problems for handmade.
Total level of accuracy for every structural element could be maximally 4mm and majority of house joints will be pressed too tight or left freely. Situation about house compaction, screwing of logs and shrinkage will be very complicated because everything is tied fast and even separate joint could spoil final result. Besides situation is endangered by difficulties to keep normal shape, depth and width of bottom groove. It is also almost unreal to meet four cone-shaped surfaces in exact point and do control all slopes and reserves of joints.
You can often meet inadmissible faults in proportions of joints as it is hard to anticipate catching lot of heights – side walls, top of apertures and window-sills, bottom and top of roof support logs or ceiling beams, outside and inside rafters, grooves for ceiling panels, terraces and lot more. Each carpenter has his own style and methods which sometimes raise conflict in constructions and brawl between workers, but finally customer will have wrong constructions, chinks after compaction and house with entangled outlook of joints.
Almost all joints are more or less weakened by too big angles used for cone-shaped surfaces, over deepened chainsaw, rough cuts from axe or chisel, empty space inside, chinks (as accuracy can be also -4mm) and cracks. In the same time joints have inner pressure from some bumps, hanging on top part, bended surfaces of cone-shapes and other problems tied with accuracy + 4mm. Duality of situation is reason why joints are opening chinks, screwing, moving aside from position and even breaking in the middle.
Wood structure is heterogeneous (branches, winding fibre etc.) therefore lot of wooden pieces will be accidentally broken or torn out and that will create fatal chinks into joints and between logs onto bottom groove. Way of treatment by rough hand tools such as axe, hammer, chisel and chainsaw can’t compete with quality of job done by high-speed cuts.
Small metal staples 5mm are used to connect logs inside the corner joints, but anyway huge pressure from house weight are moving logs aside and experience shows that chinks are growing afterwards. Electric cables could be installed only in dangerous and mutilated ways, but expenses will be more. Winding through foundation joints will be guaranteed as they can’t be handled with extra lugs. Later on every type of handmade joints requires more insulation materials or customer should squeeze them into chinks again and again.
Perfect quality of handmade houses could have at least double price, but unfortunately such a wasting of money will never help to reach outstanding standard of our quality!
