To make this model casting I have machined the shape from solid then masking the areas to remain machined grit blasted the rest to try to simulate a cast finish 14-11-10

01-01-11 Made the container cylinder ends and prepared ready for painting the one on the left was grit blasted using 190 grit the one on the right using 80 grit I will see which paints up the better

11-01-11 Been out in the workshop again made the container pistons and rods

These nine tie rod nuts have taken three weekends to complete, I have included the drawing and a picture of the actual nuts. The larger model nuts at 1/12 scale weigh 80 grams each so the real thing would weigh 12 * 12 * 12 * 80g =138Kg so I have modeled over a tonne of steel saying it like that three weekends is not so bad. The next thing is 24 10BA * 5/8 bolts and nuts to clamp them. PS the tie rods do not yet exist.
