So your tree is broke, what do you do with your saddle now? Personally I say throw it away. Most saddles out there are not worth replacing the tree in. You would never pay someone to replace the frame in your pickup after a wreck, saddles are the same.
Replacing the tree in a saddle is labor intensive and after its over you still have the same old saddle. The better option is to get a good used saddle that is in as good a shape and many times you can do this cheaper than replacing the tree.
If the saddle is something that seems impossible to replace then its worth using the broken tree as a model and getting a custom saddle built as close to it as possible. Most custom shops like us have the ability to reproduce even the most specialized trees. If that seems like too much of an investment then its not worth replacing the tree.
Most true custom saddles come with at least a ten year tree warranty if not a lifetime warranty like ours. In this case the saddle from the start is worth the trouble of tree replacement and should be of no cost to you.
When deciding what to do with that saddle with a broken tree, compare what is TRUELY worth to what it will cost to repair. Most of the time it isn’t worth the money… But it may make a great bar stool!
