Leather working methods.

There are many ways to work with leather. It's really one of the oldest and most versatile materials. Leather is available to every human and the methods of making it are ancient. Now of course humans generally don't hunt their own food and so they don't end up with skin that they need to tan. So let's skip ahead to leather products and the various ways that they are made today since most of us are consumers who buy those products ready made.

The point of this discussion is to make you familiar with the various methods that a cue case can be constructed. Not talking about protection here, I am talking about the way it's put together and why certain methods are used.

A case can be as simple as folding any piece of leather over and sewing up the open side - you have a leather container. Or it can be as complicated as cutting many parts to exact measurements and carefully assembling them.

All leather is not equal. Just because a product is said to be leather doesn't mean it's good leather or well constructed. "Leather" does evoke a certain amount of comfort and durability in people's minds but the fact is that leather itself while a great and versatile material has a wide range of qualities, not all of which are suitable for all uses.

Leather is heavy as well. So figuring out the best way to bind heavy material is not always an easy chore. Sewing is generally thought to be the best way and the double needle saddle stitch is considered to be the strongest sewing method. This is because when done properly the saddle stitch is essentially a knot at each stitch point meaning that if one spot breaks the rest of the line maintains strength. This method of sewing is also the most labor intensive. Machine stitching though is just as strong when done right and important to remember that military gear is all machine sewed.

So not all hand sewing is automatically strong or properly done. Nor is all machine sewing weaker.

----------------------- I have to go for now so this is where I will stop for the moment. ----- I will update this post later with more information and pictures and videos - let you know when -

Ultimately the goal here is for you - the consumer to be able to pick up any cue case and be able to inspect it thoroughly armed with real factual knowledge - so that YOU can decide if it's worth your money or not.
 
I missed the part where you put thin leather over cardboard on your cases where most use plastic like Fellini,Engles , Justis and Volturi or am I wrong and they use cardboard as well?
Maybe Jack and Roger could chime in I do know Fellini and Engles do not use cardboard it is a plastic tube

Not sure what you are talking about Ron. If we make a tube case then there is a plastic tube where a tube should be.

If we make a semi-hard case such as a butterfly then we might use some fiber board to add structure. That is a normal practice in leather working.

It depends on the type of leather used what methods are best suited to achieve a well made case.

We use many types of leather Ron and we have the experience of 23 years of leather working to allow us to choose what we feel is the best method for the materials chosen by the customer.

Also I would love it if other makers want to chime in because we have a lot to discuss.

We use many types of stiffeners. Each one specifically chosen for the application.

Sometimes Ron it's not wise to use only leather on a cue case. Sometimes it's much better to add some reinforcement to insure that the leather isn't taking all the stress. Any good case maker knows when a stiffener or reinforcement material is needed and what the best choice is.
 
Ron, that fibre board should be alright in a case as long as you don't submerge it in your bathtub for a week. :-)
 

That is woven cardboard Ron. That is the best available and any good leather goods maker will use this or similar extensively if they need to stiffen the leather.

Nappa leather for example is too soft to use by itself for the type of tube case pictured. So we bond it to this board which is especially engineered for this purpose. I can understand your ignorance about this but this is a staple in leather working for bags, cases, briefcases and shoes to name just a few products.

This is an example where we used nappa and a gator print. Both leathers are too thin to be used without bonding. So we bonded these leathers to the cardboard stiffener and to leather depending on the part.

For this one we bonded the elephant print to cardboard for the body and then veg tan for the lid. We also use goat skin to reinforce the lid at the stress points where the parts meet.

Here is an example of why we use many different methods of reinforcement.

On this brand new unused case, not our brand, the leather is already tearing at handle.

Appears that the product is used for shoe insoles and is an engineered product and not even close to cardboard... Google shows several entries for the nikson 626 product.... Dunno if this was a question or accusation.. If it was the latter I see it as a fail.......

Than you Chris. I forgot to mention that bonding to this material also helps to reduce leather fluctuation due to cold and heat. As we saw earlier this year it is possible for leather to shrink to the point that the lid will not close.

Veg tan leather which has been tooled is particularly susceptible to this type of movement.

We try to make as tight a bond as possible to reduce movement in any direction.

This is a 2008 case which has been bonded to the board substrate. Anyone can see that it is in perfect condition after nearly six years of use.

In contrast this unbonded part in red and black is already developing stress fractures because it was not properly constructed to allow for the bend. This case has never been used and with use the problem is likely to get worse. Compare that to our work on the brown case with more than five years of use on it. The bend is less because I designed some stress relief into the parts.

The brown oil tanned case belongs to me and I will attest to the durability of the construction. It's been all over hells half acre and it's still something I'm proud to carry.
Hey John...while your at it, take a look at where the local shoe repair guy attached the new lid. If you can straighten it out I'd be happier.:smile:

When I was looking for a case, even though I could afford any case in the world I bought a Barton.....and glad I did.

I will vouch that the woven cardboard when contact cemented to leather is as tough as nails. That stuff is so tough it's hard tear with your bare hands, then when you add the cement and stick it to the leather and it's a great product to use in leatherworking. The inside of pockets on the top part of the pocket is a great place to use it to help hold their shape over the years, if you don't use it they will be sagging in no time.
