I have now finished two handles in Thuya Burr for a special little lever .
As the threaded portion on the lever and the Portafilter are quite short I’ve inserted some Aluminium tube for 3/4 of the length of the handles . The aluminium was threaded to size , then knurled on the outside to be a push fit into the wood and glued .
The handles have three coats of cellulose wood sealer and finished with multiple coats of Melamine lacquer.. Sanding to 2500 grit between each coat . Finished off with some buffing. Also included a picture of the finished tamper handle ..
