I have just completed a download on how to make a miniature vacuum box for forming small boats, or other similar hollow items from stryrene sheet. The download is 20 pages in length with 5,658 words and 39 images in colour and B & W. It contains a historical article about the British full-rigged ship Denbigh Castle including deck and sail plans. And an article on making the miniature vacuum box. It took me 14 hours to research and write, so there is a nominal charge of £1.49 on it! After the link opens, scroll down a bit to read the synopsis. Then if you wish to purchase a download, a button for Paypal or cards is provided for £1.49.
Here is a picture of the vacuum box. It can make two sizes of moulds, and the image shown below has the adapter iin it for smaller items.
Here is the link: **LINK**
