As we near the end of conserving the Poor Law Union and Workhouse Records, I have been busy completing the final lot of repairs to especially damaged material and creating bespoke boxes. Today I thought I would share how I’ve been making the enclosures.
Around fifty of the Poor Law Union volumes are too large, too damaged, or otherwise poorly suited to fit inside our standard archive boxes (or would rattle around our next standard size). In creating bespoke enclosures, I was looking for a design that would be:
- Simple to make
- Create a minimum of waste board or card
- Did not require rivets (to avoid purchasing materials and equipment we didn’t already have).
After completing several tests designs, I found a one that fit the bill. Once a workflow was established, these enclosures could be completed in about 20-25 minutes each, doing four to six at one time, as the space allowed.
I choose a four flap design, made with 1000 micron (1mm) archival laminated boxboard and tied with 16 mm unbleached cotton tying tape. I based the design on this one here, but modified slightly it avoid having the abrasive tapes directly against the books (a majority of the volumes had red rot damage which was just consolidated).
Below is a diagram of the boxboard construction and measurements.
First, the volume is measured using a book measuring machine, which helps ensure that any wonky books are accurately measured at their largest dimensions. These dimensions are entered into an excel file I created with the box formula (linked at the bottom of the post). It doesn’t take much time to calculate by hand for one or two enclosures, but when completing them in batches, I found this system reduced the overall making time since the measurements could be done ahead of time and boxes completed when it was convenient.
The boxes are made from three pieces of board (protector piece A, vertical piece B, a horizontal piece C ) that are cut and creased so that they fit snugly against each other. The two pieces of equipment have been helpful is a board chopper and a board creaser, which improve accuracy and speed when creating the boxes. The pieces are then rounded at the corners with a corner rounder, and then folded into shape.
I use a straight chisel to create a slot one-third of the way from the top and bottom edge of each side of horizontal piece C. The tying tape is threaded through the slots using a piece of polyester as a needle to pull it through, this holds the tapes in place when the enclosures are tied. Pieces B and C are then adhered together with EVA and weighted down until dry.
Once it is tested for size, the enclosure is now complete!
Thanks for reading!
