Welding done

Having shopped for materials and looking around house, cutting and welding could begun. For the main shaft and tailstock I took 20mm threaded rod. I wanted with 8.8 strength but got 4.4 one. 2 metres were about 10 euros.

 Tailstock and support are sliding on two 38mm pipes. Large homemade washers clamp both of them to the bed. I added a short pipe to the supports washer to lock it between bed pipes. The nuts were made better too.
