Advice on restoration
« on: September 02, 2009, 10:15 PM »
I probably posted this http://www.radbmx.co.uk/forum/index.php?topic=94090.0 in the wrong forum, so will ask some Q's here

I know that Del can do me stickers, and I'll get them from him, will probably rattlecan the frame/forks and will use all the parts I can from original (don't want NOS if I can help it)

  • I've stripped the old paint off, and there is some pitting on the downtube.. the original (Yelllow/Black) paintjob will cover this anyway, but what is best way to remove surface rust and is there a decent way to cover/smooth pitting so I can spray over it?
  • What is the best way to clean rims (1 x Araya 7x, 1 x Araya Aero) - Ovencleaner???
  • What is the best way to tyres - dishwasher?????)
  • I need the wee adjuster for the 880 front brake.. are they available anywhere?
  • Are new hollow bolts available anywhere ... threads on mine seem a tad worn after 22 years :)
I'm building the bike to ride, not for shows etc, so I don't need it to be 100% perfect/original (I prefer my parts to the stock bits on an 87 Tem Master anyway :) )

Help is appreciated, will be cool to get this aby back on the road.. and as soon as I get double decades back, I'll post a vid :)

Here goes:

Frame -
rust can be removed using, hammerite rust remover, or T-CUT and a scoring pad (depending on how bad it is). It's best to apply a rust preventer then, esp to the pitted area.

If u are spraying it, use a bar metal stopper to fill the pits and sand when dry with wet/dry paper.. varying grades.

Then use a good bare metal primer, and spend time smoothing this down, as this will have a massive impact on the finish.

Wheels -
If u are removing a anno finish, oven cleaner will remove this, but you are better using caustic soda (just be careful), if u are only cleaning and polishing the rims. Use a good cutting compound and lots of elbow grease, then buff!.

Tyres -
some say dishwasher, but I have never attempted this, I use the bath and give them a good scrub!

Brakes -
just keep your eyes open, parts will come up.

Bolts -
No end of specialist available, use the yellow pages for someone local - and take the bolts with you.

Cheers Sid

Frame is chrome.. does that make a difference to the prep?  Original 87 Masters were chrome at the back and the fors with middle section painted

oh yeah, crap! just seen the photos..

you need to seek advice from someone like 'N2CUS', spraying over chrome not easy and it will chip and peel like crazy... maybe look at having it annodised instead...

worth doing right because its a nice bike, I could not tackle that at home and do it justice!

there is a product made by 'dupli colour', but I would wait to hear from Rad Member with experience in spraying on chrome.

Sorry Fella..  :daumenhoch:

if your frame aint flaking i sugest rubing it down with 240 grit this should key up the chrome well and then  primer it use a high build primer to cover all the scratches if your using cans give it shit loads of coats, build it up till you cant see the scrathes then use a 1000 avlon pad to nib it down, then you should be ready for painting  :daumenhoch:

How about Plasti-Kote?  Any good? or better for covering up a total mess.. I'm getting the frame pretty smooth with that foil/water trick and some fine steel wool.  Happy to keep going to get things smooth enough to prime/paint, but I've read that Plasti-kote is a different compound and adhere's to chrome better (clearly I have no idea about these things!) :LolLolLolLol:

Its gone from this:


to this:



Excuse the pics, but the result is a fairly smooth downtube so far where the chrome has pitted at the gyro cable guides, BB is still a work in progress though  :'(

Cheers 4130, I had no idea how long it would take... I said to my daughter (13, who thinks its all like soooooo cool) , that she can "help" with the spraying this weekend but I reckon its another week of night-times sitting in the garage, with tin foil, wet/dry and all that, listening to the beastie boys before I can even think about a can of spray paint. :-[

Am thinking of Plasti-kote's mediterranean blue from this range :  http://www.plasti-kote.co.uk/Product/pcode---4181
 should match pretty close to the 88 sticker set http://ajkbikes.com/catalog/popup_image.php?pID=262&type=jpg&osCsid=fc0ea6bea050056cb0428f0940bea6db
Forks aren't original Chrome Haro's, they are old Streetbeat forks, which I'll just do the same colour

Profiles are in good nick, they still had the clear plastic on one of them, just a bit of pitting on on side.  They're 185's so feel huge, I got them from a spoiled kid in Cape Town about 20 years ago, I was there, and he had no idea how good they were.. Think I swapped him for a Vision Street Wear T Shirt :)

Brilliant, thanks Kuwahero.. give me perfect pics to base the painting on..
Yellow is cool, but I don't think I'm that keen, the red is nice too.  Mine was a pre-prod, so got the Turquioise from 88, I see the 88 brochure is there too, downloading now.

Many thanks.. will post pics when its in better shape :)

OK, progress so far:

Frame is now as smooth as I can get it.. pretty good tbh. I've keyed the frame and put a coat of primer on, looks pretty smooth, will do a load more and get some 800/1000 grit and make it ready for colour.  I've ordered black/black 88 Master stickers from AJK http://ajkbikes.com/catalog/popup_image.php?pID=266&type=jpg, and del's sorting me out with a peregrine CD decal too.  Decided to go for black/black so that its easier for me really - matching yellow/coral/blue/turquosie would have been a nightmare probably.
Forks are a nightmare to strip.. I've nitro-morsed them and taken most of the crap blue rattlecan off, but they are powder coated underneath with the white/lavender colour that streetbeat forks were in 86 or thereabouts (and no they aren't salvagable as originals, they are badly scratched all over) - whats the best way to remove (without going to expense of blasting)

ACS RL Edge tyres have come up well after some scrubbing, and the Araya rims have now pretty much got all the brake makes off.
Need to work on the DX's to get all the paint off, I think back to silver will be best for them
Hutch donut is defo staying on the bike.. no idea where I got it, but its pretty much perfect condition after a clean.
Haro Group 1 stem looking OK, but could probably do with new allen bolts to keep things shiny
Will post pics when I've got the frame painted

Whats the best way to protect the paint?  Lacquer, or use plasti-cote glass black in the first place...
Clear film over the frame to pretect - is that a retarded idea?  if its not should it be done over the decals, or will it knacker them
Cheers

OK, progress has been slow, but I've stripped sanded, primed and plastikoted the frame (still trying to get the old skyway colours off the forks)



Basically not too happy with the finish I've managed to get with the Plastikote, you can see on the downtube that its a bit rough - probably down to impatience, and lack of sanding on the primer (frame was v smooth)

Anyway, I'm just back from dropping it at the local powdercoater, along with the forks and the top of the Group 1 Stem, so in a week I'll have a decent finish on the frame/forks.  Have got the decals from Del which look v cool.  Powdercoater guy says he can keep the back section chrome and it'll all work out OK

Woody bars are pretty dull chrome now, so thinking of maybe re-chroming, but not sure I want to go to the expense.  No doubt when I get the frame back it'll change my mind though
Searching for some nice 48's to put on it too, and when I'm looking I do like the look of Tuff II's again.. I rode them for ages in the 80's, and I see that Grey ones are available for about £70 if you look.  I think that would be pretty cool

Got my frame and forks back from powdercoater today and am impressed with the difference between this and rattlecan, its totally worth it (got frame/forks and top of stem done for a mere £35 by a mob called P&J Powdercoaters in Glasgow)

Stickers supplied by Del now on the frame so looking pretty good.  (Many thanks Del)


I've built a fair bit up after this with original parts (this isn't a show bike, I'm gonna start riding it), and hopefully I'll have pics of the full bike over the weekend (Its taken me all night to get those profile cranks back on!)
I've also discovered the joy of Autosol, so my Araya rims are coming up a treat!
