I did a post somewhere with more details of the process  ...  I'll see if I can find that. Weight is not really an issue when winding because the core sits in one spot for quite a while  ...  then you jiggle it around a few degrees to get to the next section. Well that was my experience anyway. My big tx was certainly heavy when I finished and difficult to move around  ...  but I didn't find it an issue to wind. It's about 57 or 58kg now!!! Hopefully Mark will start a new thread so others will see it and chime in.
