Shaping work is done. Only 1 coat of garnet shellac so far. The handle wood is Walnut.

Hi Stewie,
that is certainly a very well made and designed handle. But I've two concerns.
The first one is minor: the curve on top of the upper horn could be more fluent.
The second one is bigger or even minor: You've reached a design, wich is classic but no longer
identifiable as a "Stewie Saw". This saw could have been made by Tyzack, Eadon
or Spear & Jackson. What could be what you or the future owner of the saw wanted on the other hand.
Cheers
Pedder
ganz kurz: ich finde die Kurve am oberen Hörnchen könnte gleichmäßier und ich finde Stewie verlässt seine Designlinie

Hi Pedder. I will double check the top horn curvature tomorrow. Appreciate your thoughts on the direction of my saw handle designs.

Work on the saw plate assembly is now complete. The handle has received its 4th coat of amber shellac. 2 more coats remaining. After the last coat of shellac I allow 5 days for the shellac to further harden before I work the surface down with a cutting paste, then buff to a shine with a powered mop.

While I wait for the shellac on the Walnut handle to harden before buffing the surface to a shine, I am shaping another backsaw handle using Queensland Maple.

When I use shellac on my saw handles I apply a total of 6 coats. The 1st coat is sanded back to 150g. The 2nd coat to 220g. The 3rd coat to 400g. By that stage I expect most of the grain should be filled within the wood surface. The flat faces of the handle are always sanded over a glass surface. The time delay between each coat is minimal.
The last 3 coats of shellac are to add depth over the wood surface. Each is given 24 hrs between coat. Each coat is lightly abrading with a very fine grade sanding pad before the next coat is applied. After the last coat the shellac surface is then left for 5 days to harden.
The shellac surface is then lightly rubbed back with a cut and polish paste that's hand buffed to a shine. To achieve a greater shine, the surface is buffed again using a power mop fitted to a pedestal drill. (no cut and polish paste used) This step is again repeated 30 min later.
Job done.
