i scraped the brake rims away to clean and then went through a three stage wet and dry paper sandaway - i then had to get the original shape back and make them smmoth and look like were back in the day - then stuck them in bleach for a week to get them back to white  (just waiting for swivel to send me some decals to finish it off)

you can see that if you put in the hard work, you can sand back to mak them look clean again and back to the right colour - it just takes time - the smoother you get them they will look a better colour as the is more solid

cheers B  ;)

B your resto work is always impressive fella and they look well sweet  :daumenhoch:

im about to strip the wheels now and make a basic start to see what direction i need to take with these puppy's

cheers for all the advice so far chaps  :daumenhoch:

BENDYCAT ELEVENTEEN:
Take them all apart - carefully and slowly as not to make the holes/nipple to spoke any bigger (they do get bigger when used as the wheel flex's it moves the spokes)

give them a good wash - theis will get some of the dirt out and grease off so you can see where to start - a dish washer is good for this or just a bucket of hot soapy water

Sit out side and get a good lock on with one hand and use you knees or feet to lean on

don't go to higher grade of wet and dry - the smother you start the easier it will be to get it smooth - 600 - 800 -1200 - you can use a razor/stanly blade but i'm guessing you don't need to reshape them and get them back to white and they are blue (but it is up to you and you need to know how to get the best out of a blade and how it works the item and not dig in or cut lines )

do one side with one grade of wet and dry - then go onto the other side and the same with the other rim - this way you will feel with you finger when you get a good smooth finish and both will look the same

just keep working down the grades til it's silky smooth - you learn as you go on through each grade

any prob pm me

cheers B

oldskooldayz:
Right some great advice on this topic so big thanks again  :daumenhoch:

i dont want to start useing a stanley on them in a big way as i dont think i have the skills to do what is required so will take it very slowly and use one on selected small area's  :daumenhoch:

i have just stripped them and they are now ready for the dish washer, i actually asked my wife if it was ok to use her most valuable machine and the answer was simple

if you break it your doing the dishes for the rest of the year and buying a new one  :LolLolLolLol: i just fooking hope it dont damage the wheels i told her  :LolLolLolLol:

again she replied why dont you just put the whole fooking bike in  :LolLolLolLol:

anyway stage 1 underway peeps  :daumenhoch:





Now i went down the lazy bastartd route of just cutting the spokes with wire cutters  ::) ( they were shot bent and loads wouldnt undo )

but i am faced with a little bit of a prob and that is the front hub has a buckle in it one on each side of the hub





one is a good 8-10 mm out the other side is about 4-6 out, is this a case of put them in a vice and straighten out with a plier type tool ?

oldskooldayz:
Just took them out of the dishwasher and they look the same  ;D

But and a BIG but I have found a split in one of the rims and am mega pissed off now  :'(

they are hanging on by 5mm each side of the outer rim and 7 mm inside rim

can i fix this to ride them or is it goodbye sweetheart ?









as you can see with a little pressure i can open the rim up

theRuler:
That rim is scrap mate.

And in future, remove the freewheel while the wheel is complete!!!
