hi
great job, I will not go as far in my cabinet restauration, to hard for me.

for the métal buffing, you just have the right tools and is easy.
to draw, it's an another story.
hurry to see more, good luck

hi, just some informations.
the grain size of the flap disc is about 240.
Here the drive kit that I use with an électric engine ( 1500watts)
disc (resized).jpg

if you not have the flap disc, you can use sand paper 240/ 400.

to clean the coin door, it's not easy, you mustn't use the flap disc.
it's better to used water sand paper about 400/600 before polishing.
it's the same for the siderails, but be careful with them, it's a little dangerous.
be careful that clothing is well bonded to the body.
roll up our sleeves, pay attention to hair as that can be caught in the machine.
and of course mask and goggles and gloves.
to clean this part.=>
