Green Hammerite was the original colour of mine so you may have just reverted back.
The guide block faces can be smoothed in the same way that you would sharpen a plane, all you need to do is make sure you maintain the original angle, if the sides have been mangled by the holding screws just flatten them in the same way. The guide blocks should be long enough to regrind the faces many times
(lower guides) and they are reversable.
The table never slid smoothly. Paste wax almost every where will help. I can probably count the number of times I have tilted my table on the fingers of one hand.
I should probably check mine and disassemble my table (I never have).
The thrust bearing that is badly scraped and partly ceased will be the top and if you cant get it off then just swap it with the bottom. That one will be in near mint condition. BTW if you do get it off and get a replacement could you give me the detail of the bearing? I should do mine too.
It isn't clear from your photo the condition of the upper guide bar plate, the one you tighten it against. This should be about 1/4" steel and flat. You can see it in the 3rd photo on my website
here. If it's not flat then flatten it. & if it's not flat this is probably due to the fact that the original design was for a thin, light aluminium blade guard (on the table in
No.10 No.11 No.12) and yours is a later version and steel.
BTW I see you have an original Elu router table. Do you have the complete router accessory set that it's part of? With the clamps it makes a nice horizontal table.
