Maik, the main problems the weight and size, too much hassle to move from house to workshop and then back to house again every time it’s worked on. My old workshop was nearly 10 times the size of current one, but was even worse for humidity and condensation. Had a de-humidifier going 24/7 but it could only do so much and many projects, tools and machinery suffered badly over time.
The big rectangular ‘treasury’ door (started about 1985 I think) was actually so bad I eventually salvaged lock and parts and ‘scrapped’ it. Learned a big lesson from that but even so my current ⅙ scale steam locomotive (started 2004) is also showing signs of corrosion on many of the steels in my current shed. One of the disadvantages of living on the coast and the salt air I suppose.
Im still stuck for a solution to thousands of pics stuck on USB memory sticks with no PC or laptop, and a house now full of IPhones and iPads!
Also, I’m from a time before digital cameras when a really good clear photo meant having some photography skills with a manual SLR camera, and faffing around for ages to get the settings right, so sadly things rarely worked out that good back then!
The more recent projects I have on USB stick so if I can find a way to access and transfer I could then send you pics of the other stuff
