Euro Pen Kits Assembly Instructions

Cut 16mm square blanks, to the length of the brass tubes (add 1.6mm for squaring off).
Drill a 7mm centered hole lengthwise through each blank.
Spread glue over the tubes. Insert the tubes into the blanks with a twisting motion to spread the glue evenly inside. Center the tubes lengthwise inside the blanks.
When the glue dries, square the ends of the blanks. Use a 7mm barrel trimmer or belt/disc sander to take the wood down flush to the brass tube. Turning the Blanks

Place 3-4 spacer bushings onto the mandrel. Place the cap bushing next on the mandrel, then slide on the upper blank. Place the center band or a scrap band over the center bushing, square end of band toward cap. Place this on mandrel. Use tape to hold the center band against the lower blank. Place lower blank against the center bushing, next, slide on the tip bushing, thread the lock nut hand tight. Bring the tailstock snug with the mandrel. (Do not over tighten, it could damage the mandrel). Slide the stop bushing towards the blank, adjusting to remove spaces, then tighten the screw set and lock nut.
Turn the wood down to the bushings and the diameter of the center band with chisels and sand paper. Taper the end cap and tip ends of the blanks (follow diagram C for profile) to conform with the cap and tip. Remove tape and use the outside dia. of the band to determine the outside diameter of the upper blank. Be sure the wood on the lower blank next to center bushing does not exceed the bushing diameter, it may cause the twisting mechanism to jam when parts are engaged. Sand down to the final size.

Keep the center band away from the upper barrel. Make a pencil mark 6mm from end. Use a parting tool to cut a 6mm tenon down to the diameter of the bushing.
Use the center band by sliding it over tenon to achieve a good snug fit. Make sure you keep a sharp outside 90˚ corner on the tenon. Finish, polish and wax both barrels.
Use a finish of your choice but be careful if brushing on a poly, etc. You can stick the tube, bushings, and mandrel together.
