Thank you all for the nice words about the model

The important for me is that it got my WWI mojo bacv

This model is very nicely done!
How do you get the lines for the wood layers on the propeller blade so clean and straight?
Any tricks for that? I have struggled with that myself, using colored pencils and free-hand drawing on the blades. I find it hard to get them as straight and even as you have done here.
Well done!
I just glued two colours veneer together and then carved it

this way lines are perfect... I am doing this now for nearly every model. The first time, few years ago, it took me 4-5 attempts untill I get a fairly good result. Nowadays I usually succeed from first or second time max. SO just try it it is not that hard and there should be tutorial somewhere on the forum

best regards,
Sasho
