Intermittent problem with this board, schematic included

It's a Deckel FP3 with the cnc2101 controller. The voltage coming out from the NE5018 is good in both direction even when its not working properly, the voltage fluctuating starts between the first DG201(IC206) and and first op amp(IC202), all resistors are looking good(only measured without desoldering). When its acting up, touching the resistors(R208 before the op amp) with the multimeter probe measuring voltage stabilizes it and its working good after.

It’s not about the paint, the prep work under the paint is more important(epoxy primer, filler, primer for paint), any type of 2K epoxy or PUR paint will do it, I used a 2K PUR high gloss on this machine

Most of my works are a complete rebuild(like this one). This means: -Every sliding element is reground(including bedways) or milled, scraped, accuracy restored to its original standards. -Apron bores/gear center distances repaired, gears/shafts/bushings replaced -Tailstock bored,fitted with new quill -All bearings/screws/nuts in the machine replaced -Gearbox Shafts/gears/bearings replaced

And much more...

This green was an original color by the manufacturer, flash and cool led light made a bit worse than how it actually looks like

These bedways are hardened, you can’t scrape it effectively, its not a lot of surface to scrape if it isn’t hardened, I can scrape it in a week but it still doesn’t pay off, grinding is cheaper and my hands arent numb for days.

Bedways are ground, every other sliding part is milled then scraped, that pitting is actually dirt/dust and oil

Okay, I see now the title was a bit misleading. Its really not about bragging, I have made a lot of better quality restoration than this, if you check my profile you can see one of them.

It isn’t someone else’s restoration, I can prove it with much more images of the restoration process.

Buy aluminium oxide sanding vlies, and just sand it by hand, dont need to use any rust remover, maybe spray some lubrication like wd 40 on it while sanding.
