Do all my wood cutting by hand with a scroll saw for circular stuff
i find a hacksaw blade with an electric tape handle very helpful ( the fine tooth one to cut steel)
i do have two saws with wooden handles that i got at the hobby shop ( do not remember the brand name )
One fine tooth and one coarse tooth use the fine tooth mostly
Cut metal screws bolts brass tubing wire landing gear with a dremal and a cutting wheel from the LHS ( or tower )
I am only cutting balsa wood up to 1/4 inch and 5 ply 1/4 inch ply wood
i would usually purchase light high quality balsa and plywood to replace any wood in a kit that is to heavy or inferior quality
Enjoy
