Got the hubs for the rear beam sorted. I've also had a few messages about the type of paint i'm using, how i prepare things, whether i'd recommend etc...
I'm not an expert at this by any stretch, just a hobbyist restorer who's making mistakes as he goes along and learning through experience.
But for anybody interested in the process here goes. If you're only here for waxed-up-wednesday look away now
And if any professional or experienced restorers look on here, i'd love to hear any advice, tips.....
So the first job is to disassemble the part.
I then fully degrease, descale and remove any rust. I don't have a shot blaster at the moment which would make this job so much easier, so everything is done by hand. I also use Bilt & Hamber Surface-HD degreaser, but i guess any quality stuff would do the same job.
As you can see there's quite a lot of pitting, but i'm not overly worried as most of the hub is covered by the rear discs and rust protection is the goal.
I then cover the parts in B&H DEOX-GEL and then cover in clingfilm to stop it drying out. I used to be a big Evaporust fan but i like the GEL as a lot of the restoration i do involves parts that are too big to dip. I'm also going to try the DEOX-C soon which is a concentrated powder which you dilute in water.
I usually leave the part wrapped for 12 hours. I find any longer than that the GEL is harder to clean off. As you can see the results are pretty good and the steel is nice and clean. More importantly it's chemically clean. I remove the GEL with warm distilled water.
Next i coat the part with B&H Hydrate-80. I love this stuff. Basically it's a rust coverter which leaves a lovely deep Black rich barrier. From the website - its electrochemical function stabilises existing corrosion by converting the iron oxides into a protective metal complex and it also combines with surface moisture and oxygen depriving the corrosion process of the conditions it requires.
You can see the results here. This is after only two coats. It doesn't take long to dry either, providing the room is a reasonably warm temperature. In the winter i'll usually stick a small heater on in the room, as the effect isn't as good if the temperature drops below a certain amount of degrees. At this stage you could just go ahead and paint it with an aerosol or stick some Expoxy-Mastic on top, but i like to go one further.
This is the part with some H&B Electrox zinc primer. I use brush on, but you can get it in aerosol for a better finish. I usually stick a couple of coats on, then lightly rub the brush marks back with wet and dry. On this part i've avoided applying primer to the mating surfaces as it's pretty thick stuff and the Hydrate-80 will hold back any corrosion once the two parts are reassembled.
Finally i apply some H&B Epoxy-Mastic on the inside of the part, but cover the outside with a satin Black aerosol. In this example i've lightly coated the mating surfaces as i'm not fitting the parts for a while yet. I'll rub the mating surfaces back a bit before reassembly.
And that's pretty much it. The beam on the other hand has a lot more coats of everything, but i follow the same process as above.
Just the brackets to do, then that's another job out of the way. Thank you for reading
