Picklez:
So I'm just trying to show a little :radbmxsmilie: spirit here, and do another member a little favour.

A while back on here a member had a Wanted ad posted up for a silver Dia Compe MX1000 caliber. Another member (selling his brothers stuff, can't think who that was  :-\  :LolLolLolLol:) offered a faded red example. The guy looking for one wasn't too sure about stripping and polishing so I offered.

As such I thought I'd run a little thread on the task, in case it inspires others, as it's really not too big a job. Anyway, enjoy:


So as it arrived (the control's just obscuring the senders address):






And then stripped down as much as possible:




Then out with the 'scary stuff':








Then after 1 minute - you can just see the colour starting to come off:




and 3 - you see lots of foaming as the acid takes grip:




and finally 5 minutes in:




and et voila (SAFETY WARNING!!! wear gloves unless you have leather hands!  :LolLolLolLol:):




And then the second arm:




same process as above, but also taking a mini bladed screwdriver to get into some of the difficult areas:




Now this arm was being a bit of a basket, around the recesses




So, normally this just means, no worries, round 2




But interestingly this area has proved a little madam. The ano just won't shift (in fact it seems to have spread if anything after a second coat - not had that happen before). So thank god it's getting a fresh decal over it  :LolLolLolLol:. Anyway, after a further 5 plus minutes on the second arm and a good run under a hot tap (very important to get all of the acid residue off as otherwise it will continue to work away and start to eat the metal):












That's all for now folks. Tomorrow we'll 'see the light' when the polishing starts.

Then some fettling work will be required to assist the quick release back to a more natural shape:




Oh yeah, and wifey came out to finish loading the dishwasher midway through my antics  :LolLolLolLol: Needless to say she knows me well by now and just chuckled



Enjoy, and tune in tomorrow if your interested  :popcorn:

Oh yeah, if the new owner could please check their pm and let me know whether they'ed also like the lever stripped it would be much appreciated. Cheers  :daumenhoch:

Great job so far. Dia Compe calipers/levers polish up a treat. I'm sure they'll end up looking amazing  explosion

Yes, should do, my last turned out like this (so hopefully this guys will look ok):



Only part I'm unsure on is how well the QR will finish up, but I'll give it a good go for him  :daumenhoch:

CustardLips:
Try some nail varnish remover over the unaffected area Pete... could be a little sticker residue left on there. Oven pride won't shift the anno if there's any traces.  :daumenhoch:

You actually left the original decal on the brake in that recess, you can see the edges of it in this picture  ;)
