Another Classic Briefcase



Having build a few of these already does it make sense to make yet another post about it?
I think it does as the process and techniques changes every time. It might not be big changes but even small improvements can make a big difference.

A while ago I stumbled upon a domestic website that offers laser cutting in many different materials. The prices are very reasonable so I used this build to get the pattern exactly right so that I can have it cut in 3mm acrylic.

After only 8 months the briefcase has darkened a considerable amount. The polished brass has also oxidized to a rich dark color.

Classic English Briefcase with a slightly different design No.2

4


The briefcase I'm going to make is a replica of this briefcase. It is basically the same as this one but with a longer flap, different color and thread. In this build I'm also going to use Natural Veg Tanned Tooling Butt from metropolitan leather with a thickness of 3,5mm and with a smooth finish applied to the flesh side much like the leather I normally use.
I had planned to make the gusset of Natural Veg Tanned Tooling Shoulder also from metropolitan in 1,5 mm thickness. This a bit thicker than what I normally use but I made a test and it seemed to work. I ended up using my "normal" leather for the gusset as the leather from metropolitan was discolored when I applied water to the folds. Actually I made the gusset 3 times as the second gusset had the wrong color. Something I did not notice before it was already done

Briefcase with 3 piece gusset

8


This bag is different in many ways form the briefcases I normally make. First of all it has a 3 piece gusset which is something I have never done before. Also it is made from undyed leather which is actually very different to work with compared to dyed leather. This came as quite a surprise as I was not excepting any major differences. The undyed leather gets marks and scratches much easier. Also when bending it around a buckle it is not necessary to wet it to prevent it from cracking.

This bag is very heavily inspired by Boles single minister briefcase: http://shop.boletannery.com/collections/frontpage/products/single-minister-briefcase

Also thanks to WyntonMarsalis for advice regarding the construction of the gusset.

Pattern for the briefcase with 3 piece gusset

6
If you decide to use this pattern remember to double check the dimensions and change them to your needs. Also take into consideration that this pattern (like most of my patterns) is not perfected in any way as I only have made one of these so far.

Things to be aware of is the spacing of the holes for the handle in the metal strip. I made them 18 cm apart but it really depends on the width of your handle and the billets.

Regarding the billets I might make them a tad smaller next time. Also if you do not want the extra d-ring for the shoulder strap the strip on the billet should be shorter. This again will change how the holes in the metal strip should be placed.

For the gusset I made the channels for the bends 1,1 cm from the edge. You might want to take this down a bit to maybe 1,0 or 0,9 cm instead. Adjust the pattern accordingly.

Briefcase handle

1
The handle is more or less the one from Al Stohlmans "The Art of Making Leather Cases, Vol. 2" page xx. I made it a bit shorter and the filler is also like 1 mm less in thickness.

3 piece gusset

0

I have never made a gusset like this before so some experimentation was needed to determine the best way to do it. You see that the stitching is on the bottom and not on the side of the gusset as most people tend to do. I prefer having it on the bottom as it gives the side a more sleek look.

Briefcase front

2
The front piece is very similar to this front piece. The biggest difference is that a pocket is added on the back side.

Here I put the lock where I wanted it to see if it looked okay.

Briefcase back

2
As always I cut the back piece to long. When making a new design it is hard to determine the exact dimensions so having a bit extra you can cut off is a really good idea.
As you can see here the back piece is a bit too long.

Briefcase shoulder strap

1
The shoulder pad for the strap has a slightly different design that what I have done before. The strap will run in between the two layers of leather in its entire length. The thick piece of leather is cut to size and the thin piece is cut a bit oversize. The two pieces are glued together along the side.


After they have been glued together trim all around the edge. Scribe a line for stitching 3 mm from the edge stopping at each end so that the two end of the lines are 3,6 cm apart


Sew it together and burnish the edges:

The straps are made as usual. See here and here

The start of the holes start 6,5 cm from the end.
