Hi folks,
the last thing I want to do is show you radsters how to suck eggs :angel:, but I thought someone may find this thread of use, because we all start somewhere ???
Over the next couple of weeks - I will be restoring, mirror polishing and lacing these rims, and I will update the thread at each stage with images of how I am getting on.
Current state:
(http://www.radbmx.co.uk/archive/albums/ii368/sid1972/Picture015-1.jpg)
Stage 1:
Removing stone chips/dings and marks, tools needed and the methods I use.
Tools I start with.
(http://www.radbmx.co.uk/archive/albums/ii368/sid1972/images2.jpg)
Locate all the marks that are on the rim.
(http://www.radbmx.co.uk/archive/albums/ii368/sid1972/Image3.jpg)
This is the important bit , localise your repairs because the more marks you make the more you have to remove. Spend a bit of time choosing the right file (start with the smoothest to prevent over kill), apply light pressure all in the same direction.
(http://www.radbmx.co.uk/archive/albums/ii368/sid1972/image4.jpg)
This is how it should look finished. Work round each rim a couple of times to because you will miss some. :coolsmiley:

Next stage removing the anno with caustic soda.. :daumenhoch:

Cool thread,looking forward to this :daumenhoch:
-
yep...me too..excellent. :daumenhoch:

Can't wait to see these progress as i nearly told Spen to leave them in my boot on Saturday ;D

Good on you Sid , you're a thoughtful chap :angel:
Like you said , some members , who hadn't tried , or wern't sure what to do
will find this really helpful and hopefully have a go themselves at a bit of resto :daumenhoch:
Very satisfying too , DIY ::) :D
-
Nice one Si :daumenhoch:
They look very familiar those rims though - are you doing the hubs too? Some numpty had a go at polishing the rear hub and made a pig's ear of it I'll say :LolLolLolLol:
See you saturday for a quick brew - I have a boat-load of frames etc to pick up from Metal Magic finishers :shocked:
-
I am always scared of how far to go with removing scratches, shall look forward the finish here, got some rims to do in the new year.
-
kin ell si,looks like your playing a game of operation with all those little pick things :LolLolLolLol:
-
thanks guys - I will keep it running ;)
I am always scared of how far to go with removing scratches, shall look forward the finish here, got some rims to do in the new year.
Start off with the smoothest file and try to keep it flat - it is difficult to file it all away, trust me ;D
Spen - sorted front hub out and defo for a cup of tea.
-
just started to look at my concave 48s with redline hubs for re store looking farward to more posts :daumenhoch:
-
This has the potential to be a great post :daumenhoch:
Good on you

Looking forward to the progress on these Sid :daumenhoch:

Stage 2:
I 'm now happy that all of the deep marks are out - they look patchy to say the least, but ready for the next stage.
(http://www.radbmx.co.uk/archive/albums/ii368/sid1972/DSCF1225.jpg)
This is the secret solution, most use 'Oven Pride', which contains about 17% caustic soda and it's this that removes the anno not the rest of the crap in it. You can get this from any chemist, just read the label and respect it! I get as many items together as possible and then use the liquid to clean the drains after as well. It's cheaper and it will take about 1 to 2 hrs to strip the rims, not over night! :daumenhoch:
(http://www.radbmx.co.uk/archive/albums/ii368/sid1972/dscf1227.jpg)
Other Items you need; Gloves,mask,googles, mixing stick and a plastic container you can stand the rims in.
(http://www.radbmx.co.uk/archive/albums/ii368/sid1972/DSCF1226.jpg)
I stand them up, so I have more control rather than having the rims submerged, it also keeps them separated and allows me to spin each rim as the anno is removed (it's not unusual for one to strip faster than the other). (http://www.radbmx.co.uk/archive/albums/ii368/sid1972/dscf1228.jpg)
Put about 4 and half litres of water (warm) in to the tub and mixed about 200g of caustic soda.
(http://www.radbmx.co.uk/archive/albums/ii368/sid1972/dscf1229.jpg)
Stand back and watch the vapour begin to raise, this is the solution begining to work.
(http://www.radbmx.co.uk/archive/albums/ii368/sid1972/dscf1231.jpg)
Rotate the wheels, roughly every tens minutes..
(http://www.radbmx.co.uk/archive/albums/ii368/sid1972/dscf1236.jpg)
It took about 45mins to get the rims totally clean and stripped, rinse everything down with loads of clean water and thats it!!

Getting there folks! ;)
thanks for the comments also.... :4_17_5:
-
Top thread fella ;)
-
i find it only takes about 20 mins to strip in oven pride si :-\
-
Interesting thread this.
I normally put a couple of bricks or similar in the tub so you use less water and waste less soda. (adding the same amount of soda to less water would strengthen the mix and should speed up the process.
The best setup I have used is a big round tub (like the ones you dye/bleach your tuffs in) with a smaller bucket in the centre (needs a brick or similar inside to stop it floating :D) so you have a moat big enough to drop your rims into. No rotating required with that method - just place the rim inside and walk away. Sorted. :daumenhoch:
-
i find it only takes about 20 mins to strip in oven pride si :-\
::) tbh it depends on the anno - I have stuff thats not shifted for days in 'oven pride' and other stuff thats fell off, this shifts it regardless!! If you submerged the rims it would be quicker (10mins MAX), but only about 6/7 inches of the rim is in the solution for each of the ten minutes slots. Submerging you tend to get a build of a black carbon deposit - it does shift but requires more elbow grease. This for me works the best, it gives me total control and has never failed... :-*
-
i must admit tho rims are the most stubborn to shift ano,it seems that once the colour is off there is also a clear ano to shift as well unlike all the other parts,thats what had hhappened when i sent that set of rims to you si,i hadnt shifted the clear stuff too
-
::) - On some items it's a nightmare :daumenhoch:
I hope to give a few radster a clear guide on one way of making this resto achievable - like you I have felt like taking a sledge hammer to stuff :2gunsfiring_v1: :LolLolLolLol:
Resto is the best part of it for me :smitten:
Now give me some sneaky pictures of your build ;)
-
ive got nothing to show si except two boxes of bits designated to each build,one frameset is at the chromers
-
Cool! nice to see life put back into the used vharacteristic parts insteaf of fitting NOS parts :daumenhoch: :daumenhoch:
-
Looking good stripped of the anno. 45 minute seems reasonable to me. I thought you would have had to put some elbow grease in to get the anno off. Great Job :daumenhoch:
-
Hurry up Sid........... we wanna see 'em shiney >:D :LolLolLolLol:
Good work mate :daumenhoch:
-
Hurry up Sid........... we wanna see 'em shiney >:D :LolLolLolLol:
:shocked: Like 'Blue Peter '- I can show you some that I did earlier! :LolLolLolLol:

Stage 3
Sanding and Fine Finishing:
For this stage you really need a sander, mask and googles - I'm using 60 grit paper first and then 150 as the rims have corrison and brake marks visible.
(http://www.radbmx.co.uk/archive/albums/ii368/sid1972/P1.jpg)
Keep the bed of the sander flat at all times, its important that you do not press on as you will burn your power tool out. ;)
(http://www.radbmx.co.uk/archive/albums/ii368/sid1972/P2.jpg)
In this picture you can see that most of the marks have been removed, the one nearest still needs doing (before and after shot :D)
(http://www.radbmx.co.uk/archive/albums/ii368/sid1972/P5.jpg)
For fine finishing you need, a block of wood, soapy warm water, gloves and wet/dry paper (360,400,800,1000,1200 - this is the order of use)
(http://www.radbmx.co.uk/archive/albums/ii368/sid1972/P7.jpg)
I tend to go round twice with each grade of paper, checking in turn for areas that require more attention. Keep the paper wet using the soapy water, this increases the life of the paper by stopping it from becoming clogged up.
(http://www.radbmx.co.uk/archive/albums/ii368/sid1972/P8.jpg)
(http://www.radbmx.co.uk/archive/albums/ii368/sid1972/P9.jpg)
This is the finish you are hoping to achieve -smooth as a smooth thing :crazy2:
Top one completed.
(http://www.radbmx.co.uk/archive/albums/ii368/sid1972/Picture001-1.jpg)
Bottom one completed.

Good update Sid :)
I used to use oOven pride till I came a cropper doing some"Hard annodised " Pro Class III rims :crazy2:
J.T Racing told me always use Caustic , big tub , big gloves and treat with respect .
You can have a pair of rims done in 15 mins usually , usually covered in black , mind :-\
then another 15 cleaning em up :crazy2:
might as well do them the patient,, revolvo , dippo , turn roundy treatment you do instead , much cleaner
The rims are looking good already ,,,it's all about the prep :daumenhoch:
-
i use a mega strength formula, but i do loads of stuff at once. only takes a few seconds to remove. wash with a scouring pad in soapy water, then dry and on to whatever you are doing. easy peasy chris. Hard anno is just more anno. death strength caustic will eat your parts in minutes >:D
-
Blimey, 60 grit, I was scared using 240!!!, guess thats why mine still have marks then!!!
Good thread
-
Nice work Sid :daumenhoch:
:shocked: 60 grit with a power tool ...... your lucky you had any rims left :D :LolLolLolLol: Obviously works though :daumenhoch:
Great thread Sid , looking forward to the 'bling bling' ending 8)
-
Heh - just signed up and came across this thread - odd coincidence I started de-anodising a set of gold Araya Aero's on the same day you wrote this up :) Nice guide - would recommend though only using 100% caustic, as oven cleaner can pit the surface of aluminium, which isn't a bother if you're polishing, but if you want em re-anodising can lead to nightmares.......
Also found a handy container to do whole wheels in - in a local 'grow shop' - only cost £7 and will do a rim at a time.

These needed 60 grit, trust me ;) - only went round with a sander twice and I never apply pressure as such... :coolsmiley:
Thanks for the comments folks.. :4_17_5:
-
prety good work there fella but you would have been better off after 1200 using 1500,2000, and then finish off with a 3000 avlon pad, no marks and almost instant shine
:daumenhoch:
nice one Steve, I was always told anything marks that remain after 1200, the buffing process would remove ... going to give your suggestion a whirl, always learning.. :daumenhoch

::) I do that mate.. ;)

Stage 4: Polishing.
You need: a decent bench grinder, mops, gloves, mask and goggles. I have added some links of the products suitable.
http://www.thepolishingshop.co.uk/acatalog/Standard_Polishing_Kits.html
Following the instructions regarding the soap first etc. ;)
http://cgi.ebay.co.uk/150W-6-ELECTRICAL-BENCH-GRINDER-POLISHER-/270642905425?pt=UK_Home_Garden_PowerTools_SM&hash=item3f03930151
The grinding wheels come off easily to accommodate the mops - the guards need to me removed also to allow access ;)
You can also use a drill - I have completed loads of items using one, but for the price of grinder it’s not worth the hassle.
Begin by loading the mop with soap (mop spinning) - the colour of the soap will transfer onto the mop, this will only take a matter of seconds.
(http://www.radbmx.co.uk/archive/albums/ii368/sid1972/Picture004-2.jpg)
Loading the mop correctly takes practice - if the item does not polish simply add more. I black build up means that you have added to much.
I start by placing the rim in the middle of the mop and pusing it through to the bottom as the mop spins, so from 3 oclock - down to 6 oclock and then off. This follows the rotation of the mop and prevents the rim from being grabbed. Repeat this process as you work round the rim, 6 to 7 times normally does the trick.
(http://www.radbmx.co.uk/archive/albums/ii368/sid1972/Picture009-2.jpg)
For the rims centres the process is the same, just be careful not to catch the rim or your hands.. :D
(http://www.radbmx.co.uk/archive/albums/ii368/sid1972/Picture010-1.jpg)
The first rim took about 25 mins to complete..
(http://www.radbmx.co.uk/archive/albums/ii368/sid1972/Picture008-1.jpg)
and the second about the same. First set I did about 3hrs... :P

An excellent guide that :daumenhoch: that buffing wheel looks a bit bigger in your work-shop than it did in the link you put up tho? ???
-
::) it is fella - But trust me they works the same, I am teacher and that's our metal work shop. The one in the link is more for the shed , garage or in my case the cellar..

Just wanted to say what a great thread this is :4_17_5: I've got a set of 7x and the sides need some work and this thread is really helpful.
I found it by searching 'polishing rims' and had a right chuckle reading the comments/banter about that title on the threads ;D :LolLolLolLol:

'rim polishing' always brings the best out of the RADsters Doug ^"^ :whistle: :D
It is a good thread and should really be in the Tech and Resto stickies imo ;) :daumenhoch:
