The set is made of solid beechwood, and it is robust and absolutely acceptable as a basis for necessary changes. For me it is necessary: elevate the height approximately 6 cm, make the most stabile building (with cupboards for example) replace the four gourvernantes log on presses front and back with much more precise sticks quadrangles and make canals under the working table, make new online quadrilateral holes for new cams for the front of the press and the professional cams or buy them moimeme wood and metal, I will be happy after AC, I think. jannis.
