TITLE CHANGE
Ok, going to do a diary of this build, will take a while to do but will keep updated for you
(http://www.radbmx.co.uk/archive/albums/p191/carpcrazyox/mg3.jpg)
Hi, bit of help on this please.
What is the best way to remove surface rust from these parts of a frame. Sawzall did tell me yesterday of a liquid you could buy but i forgot what it was called instantly.
Would leaving it in vinegar/ lemon juice work ???????????

cheers.

oxalic acid bath
-
Tape the holes u with gaffer tape then fill the brackets with vinegar and leave 4 a week 2 dissolve the rust ;)

I reckon what Animal says would work a treat andy but I don't think you need leave it that long - 24 hours should do it - then have a scrub up session and if it needs a little more go for another 24 hours ;)
-
Let us know the results and how long ;)
-
I had an old rusty reflector bracket I removed from an mtb, and just to try it I popped it in a tub of my favourite sarsonns pickling vinegar half in, half out for 24 hours. I pulled it out earlier and wiped it off and the bit that was submerged has come out spotless, the rest obviously still think with rust.
Dont want the bracket, but it was a nice little experiment.
-
good thread andy,im in the same boat with my gusset goose!!! :D
-
oxalic is the only way imo.
-
Out of interest. Would vinegar damage paint on a mx 1000 brake if left in for 24 hours? I need to clean the surface rust off the cable fixing. Cheers Ben
-
I haven't tried oxalic yet but its not the cheapest and it means ebay which is a ballache. Tried vinegar and it worked not bad but I'm hearing good things about Citric acid has anyone here tried it? How does it compare to oxalic? Seems to be cheaper and easier to get hold of...think thats gonna be my next experiment!
-
Use oil and wire wool and a tooth brush. i did in those parts on my goose and it came up like new.
-
I've used citric in the past.
It was ok, less special than I was hoping. So I've just scored a bag of oxalic off ebay. Just need to find a bath big enough to bathe my frames in.
Chemically oxalic should work well as it is attracted to the iron oxide of the frame, ie it actually attracts rust and chemically bonds rust to it.
-
These are the latest pictures using just vinegar.

Still needs a lot doing to it so maybe an oxy bath will do the trick.
Where do you get a pot big enough for a frame :shocked: :shocked: :shocked: ????
-
Surprised with the results there andy :( Thought all the rust would be well gone - I used tesco lemon juice for just 24 hours on a seat clamp that looked like it had been dipped in sh!t and ALL the rust was removed :-\
-
I think i need to scrub a bit harder John, it didn't help that i knocked the pot over the other morning on the way to work :LolLolLolLol: The gusset hasn't been worked on yet.
Will try again tonight on the easier bits to get to.
-
I think i need to scrub a bit harder John
Andy - When i did my really sh!ty seat clamp in lemon juice the rust just fell off mate - I just gave it a gentle rub with a soft cloth no scrubbing required mate :-\
-
Right, ok sorry for boring you all :LolLolLolLol:
I have decided to do this build as a diary as such, bear with me it will take some time. For one, i'm not loaded and secondly, time is something i sadly don't have too much of.
So i'm going to build an 83 Cali special. I've been informed by the Mongoose chaps on here that this is probably what it was in the first place. There doesn't seem to be one in the museum so i'm going to work from info that John and Kev have dug up for me.
The build will hopefully look like this below, will be doing the black one.
(http://www.jpdeane.com/bmx/CaliforniaSpecial.jpg)
I've currently been trying to remove any rust that has built up in the horrible places with a small bit of success. for this i have had it dipped in hammerite rust remover, then scrubbed then dipped again.
Now looking like this.
(http://www.radbmx.co.uk/archive/albums/p191/carpcrazyox/mg7-1.jpg)
(http://www.radbmx.co.uk/archive/albums/p191/carpcrazyox/mg2-1.jpg)
(http://www.radbmx.co.uk/archive/albums/p191/carpcrazyox/mg1-1.jpg)
I have been polishing up other parts of the frame too.
(http://www.radbmx.co.uk/archive/albums/p191/carpcrazyox/mg4-1.jpg)
(http://www.radbmx.co.uk/archive/albums/p191/carpcrazyox/mg5-1.jpg)
(http://www.radbmx.co.uk/archive/albums/p191/carpcrazyox/mg6-1.jpg)
Another part that have come up nice has been the seat clamp
(http://www.radbmx.co.uk/archive/albums/p191/carpcrazyox/mgc.jpg)
I have also bought another Pro Class rim and today won a Mongoose headset off the bay.
I'm struggling to do the other rim as some of the corrosion seems to have eaten into the alloy ????? I have been sanding this down like a maniac but it's not shifting, some has but other bits are proving very stubborn.
(http://www.radbmx.co.uk/archive/albums/p191/carpcrazyox/proclass.jpg)
I have the original Tange BB and a Pro Class stem to go on but these need polishing. Also John ( Bobafett) has sold me a nice set of Mongoose bars for this project that i will collect at MK. :4_17_5: I also have a nice set of Suzue hubs and a Shimano 890 rear brake with a Pre bent Shimano lever, again these need polishing.
So as you can see from those photo's (hopefully) the chrome is not the the blingiest but is in survivor condition.
The big question is............
Would you leave as a survivor..... or..... would you get a rechrome done ???????? Obviously i'm not keen on shedding out hundreds of pounds on it.
Please bear with me on this build, it could be a longish one but i will keep this updated as of when and what i have.
cheers
Andy :angel:
-
nice work andy,i havent even started on my goose yet ;D.i really fancied going down the cali special route too but decided against it as im gonna use most of the parts on my first build for it instead and do some trades for the rest of the parts i need(lots of minty stuff to trade soon).reckon my frame is in better nick than yours just dull as hell,reckon it will polish up a beauty,the only rust is in the usual places.hurry up and finish yours so it gives me some ideas for mine!!! ;D
-
" Hurry and up and finish it" :LolLolLolLol:
No chance Mark, i've not really finished my Kuwi yet mate, sorry. :-[ Time and money will determine this. I like the idea of survivor frames to be honest so a few parts may be easier to come by.
-
Andy - i'd go survivor build on that personally. At the end of the day you picked it up cheap and you've gathered a few key bits in survivor condition without having to fork out loads. I reckon the frame looks quite nice in that final shot of the full frame as well ;)
Build her up as cleaned up as you can - she'll look nice - you can always go for a re-chrome at a later date if you think the build warrants it when yer done :daumenhoch:
That's just my opinion though bud :angel:
-
Cheers John :4_17_5:
Added a poll anyhow to see what the masses think. :coolsmiley:
-
You know how much i love a survivor... and this bike has turned out brilliant imho Andy, well done buddy :daumenhoch: :daumenhoch:
-
Think I would leave it as a survivor too mate , like bobafett says you can always get it re-chromed later if you really want to . ;)
Doing a great job by the way :daumenhoch:
-
Ok update required on my bits and bobs that have been scrounged. :LolLolLolLol:
So far i have managed to get a set of Mongoose bars from John ( Bobafett), i have removed all the surface rust from these not that there was a lot but they have come up very well.
I got a Black Aero saddle and replaced the guts with the original Viscount ones. The guts that were on there were totally screwed and they were unstamped so probably not original. I won a Mongoose Headset on Ebay but am short of the bearing race that fits over the forks, hopefully there is one in the post from Daz BMX.
I also secured a Pro class rim from Marc ( Kuwahero) these rims do need a small amount of polishing as does the Pro class stem. I also now have a shimano 890 caliper and a Shimano pre bent lever so things are falling in to place.
Now with things on this being slightly anal, i still need some Mongoose forks in chrome, i did buy some Tange ones off of Jai at MK09 which will do for the time being. The hubs are Suzue ones which i will get built up as soon as i can get the rims polished.
I've also had the rims and the stem sandblasted by a mate to remove a lot of the cack that had built up there.

(http://www.radbmx.co.uk/archive/albums/p191/carpcrazyox/goose4.jpg)
So things that are next on my wanted list for this are..............
Mongoose stamped One piece Crank
Black Mongoose grips
Gold takagi spider or Gold mongoose spider (yeah right)
Mongoose seat post
A few other bits aswell that will probably be a bit easier. The thing is, i look at those bits above and i feel like i'm banging my head against a brick wall.
Anyway thats it updated for a bit. :coolsmiley:
-
looks class so far mate :daumenhoch:
-
She'll be sweet mate :coolsmiley:
-
dude, PMd you bout forks :coolsmiley:
-
thats coming together nice now
:daumenhoch:
-
Where you hidin' Andy ??? Haven't heard from ya in a while bud - how's this one comin along ?
........get some update pics up mate :daumenhoch:
-
:LolLolLolLol:
Coming along very very slowly John, i've sort of got bored with the BMX scene at the moment but Bmxbob may have just rekindled my love affair so fingers crossed.
I've also been away on my summer Jollies so i also have post holiday blues to contend with.
Anyhow........Phil ( Sawzall) has still got some of my bits which i need to collect. I am going to get the Pro class rims powder coated chrome like Spesh's beach cruiser in the Non BMX topic place, these will then need to be built.
I've been offered a stamped Mongoose crank by someone on here, just waiting for some funds in the bank first though. I'm also talking to JimmyP over stickers for it, i'm hoping he can do a set, if not then it's off to America for them. :buck2:
Thats about it i'm afraid, other than that it's been stuffed under the stairs. ;D
Oh yeah, i'm sort of trying to finish Reeces Halfords build first, the pre bent brake lever came today from Biaggio. :daumenhoch: :daumenhoch:
-
I am going to get the Pro class rims powder coated chrome
Really ? :shocked:
That sounds mad mate - are you sure a little polish job on 'em wont suffice ???
:)
-
hey andy,mine is gonna be done by next week fingers crossed,south coast chrome promised it will be ready to collect by early next week,whoop whoop,will fire the pics up when done,i think its gonna rock in chrome with gold and black!!

One of the rims is fine but the other one has had some of it's alloy eaten away.
(http://www.radbmx.co.uk/archive/albums/p191/carpcrazyox/proclass.jpg)
Phil said it would show quite badly if polished as he had a quick go, he suggested i had them powdered silver, i then saw Spesh's beach thing he had powdered chrome and it looks superb. i reckon thats the way to go mate, it's not as if this bike is going to be ridden so i wouldn't have to worry about brake rub.
-

Looking forward to that Mark, the colour scheme sounds great. :4_17_5: :4_17_5:

Ah, right-o mate, makes sense :daumenhoch:
Have you had a quote for gettin it done yet ???
-
i voted re-chrome, there's loads of good condition cali's knocking around, nothing wrong with loosing the og chrome. unless you rides it.
-
loving these ongoing build threads , i voted for survivor , i`d keep at the polishing when you have the time , it`ll make it seem more worthwhile when you finish it because it will all be done by your own hand , and you`ll be more proud of it ( and yourself). the frame has come up superb already i.m.h.o ...keep up the good work !!
-
Ok, thought i'd get to work on the small bits i can today as i had an hour free.
MarkyP's fault as he has now inspired me to crack on with this after seeing his superb build.
My Pro class stem polished then along with the Shimano rear brake.

Time for a small update with a couple of add ons whilst listening to the football this afternoon.
Mongoose Bottom bracket fitted along with the gold Takagi spider and chainring and Mongoose One piece crank.
(http://www.radbmx.co.uk/archive/albums/p191/carpcrazyox/goose2-2.jpg)
(http://www.radbmx.co.uk/archive/albums/p191/carpcrazyox/goose1-2.jpg)
Mongoose decals and grips have been ordered aswell now from BMX products.
I also made this the other week out of an old Numberplate i had and the Mongoose vinyl that Phil gave me. Thankfully the vinyl fitted quite nicely with the all the straps on the old plate :coolsmiley:
(http://www.radbmx.co.uk/archive/albums/p191/carpcrazyox/plate-3.jpg)
-
coming on a treat that Andy :daumenhoch:
-
Looking good Andy mate :coolsmiley:
:daumenhoch:
-
Class rebuild so far! :daumenhoch:
-
What a resto - top lad Andy, can't wait to see this done !
-
Coming on very nicely sir :)
-
Update then :LolLolLolLol: How long has this been going on. :crazy2: :crazy2:
A set of pedals for it which have since been stripped properly.
(http://www.radbmx.co.uk/archive/albums/p191/carpcrazyox/pedals22.jpg)
The pro Class rims which have been powdered chrome due to the Ali rims having a certain degree of corrosion.
(http://www.radbmx.co.uk/archive/albums/p191/carpcrazyox/proclass1.jpg)
I've also fitted the stickers and managed to get some pads off of MarkyP in a trade. :4_17_5: :4_17_5: Cheers Mark mate.
(http://www.radbmx.co.uk/archive/albums/p191/carpcrazyox/goose1-3.jpg)
(http://www.radbmx.co.uk/archive/albums/p191/carpcrazyox/goose2-3.jpg)
Renthal seatpost and Mongoose grips have also been fitted.
Sooooooooooooooooooooooooo close to finishing now. ::) ::) A few more bits and pieces to go. ;D
-
Can't wait to see this finished Andy - lookin good mate :coolsmiley:
-
looking good andy,nice to see it nearly done,youve got far more patience than me sourcing all the correct parts,my goose took 3 months and that was supposed to be my long term project!!!nice pads btw!! :4_17_5:
-
Cheers Chaps, just to reiterate what i am attempting to build here
One of these below but the tyres are going to be a major headache so Comp 3's will have to do for the time being.
(http://www.jpdeane.com/bmx/CaliforniaSpecial.jpg)
The wheels have actually been built now but i need to do some work to one of the drop outs as the spindle wont actually slide all the way along it. It just needs to have some minor filing done to allow full movement. The dropout is very slightly crushed, you cant see it though.
-
Coming along nicely :4_17_5: im right in thinking those tyres are gonna be a b*tch in finding? :-\
-
its looking good andy :daumenhoch:
-
Looking great Andy :daumenhoch:
It will all be worth the effort when it's done mate ;)
-
andy simply carn,t wait to see this all done you are doing a fine resto job there mate :daumenhoch:
-
:4_17_5: :4_17_5: Looking forward to seeing this top resto work on a really nice bike.
-
Yummmmmmy Pro Class :smitten: :smitten: :smitten: :smitten:

(http://www.radbmx.co.uk/archive/albums/p191/carpcrazyox/pro.jpg)
with Suzue hubs and skin wall Tioga Comp 3's. Obviously not the tyres i require but they'll have to do until if and when i source the correct ones. More an "if" i reckon. :(
-
This is now finished :4_17_5: :4_17_5: :4_17_5: :4_17_5: :4_17_5:
Although i'm not happy with the rear brake as it doesn't work too well, i think the spring is bent or something. I'm sure someone was selling springs a while back and also the tyres are not correct. I need snake bellies for it so some old skin wall comp 3's i have hanging about will have to do.
I actually need 2 sets of snakebellies, 1 black and 1 red :( :( what a nightmare. :yahoo_silent: :yahoo_silent:
Will try and get photos done either tomorrow or Thursday, pointless at the moment.
-
'bout bloody time ::)
:LolLolLolLol:
Come on Andy - get yer pics up :4_17_5:
:daumenhoch:
-
This is now finished

Come on Andy we need PICS :daumenhoch:
