FrameSaw for carpenter and woodworker

Building a FrameSaw with changeable blades for sawing WetWood, Rip & CrossCut, CurveCut. It can be put in pieces to carry while hiking or to harvest wood in the forest. No power-tools, silent hand-tools only. While building i use my existing saw to demonstrate its functionality. Also my selfmade Workbench was of great help!

-------------------------------------
What wood is used?
- It is Rowan, also called Mountain Ash. It grows in our little forest, is quite hard, very flexible and i love the grain. The pieces used are dried for about two years.
What finishing has been applied?
- It is self-made wood finish, mixed with different plant oils like Linseedoil, Tungoil, Poppyseedoil and some Standoil. Later some beeswax will be applied.
What measurements are needed?
- Nothing else, than the length of the blade.
Where to get blades?
- Mine are made in Germany by E.C.E. They are sold by good handtool shops.
Why the handles are not self-made?
- I still had a ready pair in my storage. Only the lack has been removed for oiling.
What parts came from a shop?
- Additional to the handles, also the blades, the saw blade holders and the hempstring came from my tool-shop.
One saw for all - are there situations, where this saw is not good?
- Yes, there are! For very fine cuts, i prefer my small saw or my japanese saw. Even, if japanese blades are available for frame saws, i would prefer a smaller and more handy one. But that is just my own taste...
