hi all,gun all assembled and shooting now..thanks everbody for sharing your knowledge with me.. had the metalwork hot caustic blacked/blued.mechanics went ok once i got the correct piston head.. i machined up a delrin spring guide and top hat and made up a plastic piston liner,only shot a dozen or so pellets through it so far but it shoots quite nice for an old springer.its doing a tad under 11fpe which i am happy with.next job on it i am looking forward to ,refinishing of the walnut stock.does anyone know a good method of refinshing the gold lettering on the compression chamber?,cheers greasemonkey
