Many thanks for all yours comments guys, I really appreciate them all !
Lee is right, it's a long time I'm working on this one (but eh bro, that's about the same time you're working your ST

) and I'm not in a rush to finish it ! Just want to get it right and I want it to be the master piece of my collection because the ROTJ AT-ST means a lot for me... This movie was released 2 months after my birth !
Yeah bro you're ight for the plans lol it took 20 full days, 10 hours a day to draw the first draft then I refined them again and agaim... It tooks 7 months to get them correct and ready to be given to the machinist !
And I'm still refining my parts... just built another "8 rad" assembly for the back of the chassis because mine was off (1 millimiter too long and the angles were off by 2° and I noticed than the upper and lower parts didnt share the same angles, yeah there are not symetrical

).
Well, I go back on the feet and some explanations :
First I reworked the feet. Shortened them from the rear, reshaped the rear of them and changed the angle. I also redid the kind of rounded shields from styrene (my previous ones were from aluminium) and this time I get their shape correct. I also built the toes. The "312T parts" are scratched from brass, aluminium for strenght and styrene for details.
Then I primed them
And now that's the trick.
Plaster of paris mixed with white glue, water and sand (from Maldives, very thin

) That was a friends gift :lol I just used a few

).
Applied this mixture BEFORE the basecoat, that's very important, it was applied before the basecoat on the ILM props.
Then the paint job can begin
Basecoat from a rattlecan (the only way to get the orange peel effect that the ILM walkers have, and the only way to achieve the same weathering effect

).
Then weathering with the airbrush and brushes. Filters with oil and acrylic paints.
The next touch is the grass

Made from foam I found in my garden

Fixed with white glue then touched up with paints !
And voila
