For the brayer  I used gasoline rubber hose (for motorcycles)

2 cm the outer diameter,1,4cm the internal, (if you can find bigger  the better). Long as you want

A gas hose that I put inside the gasoline hose. 1.5cm the outer diameter, 0,8 internal.

a screw and nut, a piece of metal  1.8cm width and a piece of wood for handle

For 6cm brayer you need:

1.Cut  a 6cm long gasoline rubber hose and a 6cm gas hose

2.Put the gas hose into the gasoline, it must be tight.(soap helps if you have problem)

3. Take the piece of metal and a drill one edge 0.8cm.

4.Warp it in the vice,make a Π 3.5x7x3.5cm.

5.Drill the other edge using the first one as  guide.Grind their edges to be round.

6.Make a small drill in the midle of the Π for the handle

7.Put  a wooden handle 9.5 cm long is good ,2cm diameter

8.Put the screw 10.5x0.7 from one edge, the hose and then the nut

(i don't know how you call them, but these screws have turns only to the edge)
