Hey guys. Picked up this sweet Tempo for 10 bucks. It has a lot of rust but the paint is clean in most sports. Do you think its too far gone? If anything, I got a nice headset and seatpost binder bolt

EDIT: I got the headset, cups, and Bottom bracket no problem. . .

It ain't beautiful, but then if it were you wouldn't have gotten it for $10.

I wouldn't bother with much more besides removing the worst of the rust and some rattle can touch up. Then build it with spare parts form the salvage bin, and you'll have a decent beater bike.

It wasn't much before I joined BF that I sold a Tempo for $10 at a garage sale. It was in far better shape than the one pictured above.

I would have it sand blasted to see the extent of the rust damage, then rattle can it. Framesaver for sure as that looks to have been an outside bike.

You did okay for 10 bucks. Looks like a good winter project. As others have said, can't really tell about the frame until you clean those areas very well. You will probably find some hidden rust in other places. If after cleaning the frame it is still strong, treat for future rust problems....then you come back and tell us your plans for it.

Look forward to the report! Those are good bikes. Too bad the frame did not come with a fork. Is there tube damage near the HT joining the top tube or down tube ?

It actually did come with a fork . I'll have to post a pic.

I think I will do a Evaporust treatment first to assess the dmg. Im not sure I want to spend the 70 (sand blast and podwercoat quote) + decals for this.....Decisions

The fork is the only thing that gives me pause and is the main thing that could cause a serious crash if it failed. That said, consider this another vote for fully removing all the rust via naval jelly, evaporust and/or some vigourous wire brushing and you will be able to see what the condition is of the metal underneath. I am doing the same and then POR-15'ing and riding the heck out of an '84 Mongoose frame that looks like the BB area was submerged in the Puget Sound for a couple years.

Any tips on evaporusting? Ive seen people using a kiddy pool, but not sure a gallon would be enough of it. Evaporust is kind of expensive per gallon. Id like to fully submerge the entire frame and fork if possible

I use old fashioned Naval Jelly. It's basically similar chemistry -- phosphoric acid, but thick enough to stay put when applied, so I can brush it in the areas I'm treating vs. having to buy enough to submerge whole parts.

ALso, I believe this is an 1985 model. Is that correct?

exmechanic89

Those are sweet bikes. I'd de-rust it and if you're lucky, the thin tubes will not be rusted through anywhere. Then build it up make a cool and inexpensive racer out of it.

primo123

Where can I purchase Naval Jelly? Do i just apply it and let it sit for a day, then scrub it off with a wire brush?

FBinNY 

Most hardware stores sell one version or another. It's a water soluable acid jelly, and yes, you give it time for the chemistry to happen, but more like a few minutes than hours. Then water wash or rinse off.

Like the other products, it doesn't actually remove rust, but converts it to another compound. Depending on your application, you can paint over it, or wire brush it for a smoother finish.

Good luck,


BTW- I just looked at the bottle, mine is a Loctite product.

I'm a fan of Evapo-Rust, but I prefer oxalic acid for frames and forks. It works practically the same and it's cheaper, making big jobs more feasible. You can pick up a small tub of oxalic acid crystals (sold as wood bleach or deck bleach) for under ten bucks from hardware or paint stores like Sherwin-Williams. Mix the contents of that small tub with a kiddie pool full of water, let it sit overnight, and voilá.

1985 is correct. Under that crust is a bike that looks like this

That looks like a decent project for ten bucks. What city are you located in?

primo123

Im located in Marshall, Missouri. I am between Columbia and Kansas City.

I would start at the bottom bracket first, since there is significant rust at the base of the frame and if you can't remove the bb cups, well don't bother doing anything else.

Spritz PB Blaster or the rust penetrant of your choice to soak into the threads. Reapply daily for 2-3 days. Then give it a try, use a torch if you need to too.

If PB + patience + heat doesn't work, you may need to dip the frame in an Oxalic acid solution, basically Savogran wood bleach, about $9 for 8 oz of powder soluble with water.

The fork can be soaked too in OA, or hit it with a wire brush and poke at it with a pick.

Thanks for the tips. Fortunetly, the headset cups and BB cups all came out really easy. No troubles at all. I went and bought evaporust ( a gallon ) but spent about 2 hours and about 6 beers trying to figure out how to soak the bottom bracket completely. I tried everything, bags, cups, bowls, tubs. I couldnt find anything. I am going to go to my local sherman williams and look for some OA crystals. How much water should I mix it? What is the ratio?

oddjob2

A kiddie pool, garbage can, or a bike/flat screen box and a construction grade garbage bag. I use about 1/4 cup per gallon. HD, Lowes, Ace all carry it.

primo123

Do you have any pics of the kiddie pool or garbage can set ups? Maybe a link to a thread?

oddjob2

Actually, thinking about it, grab your frame and head to Walmart. They sell the wood bleach too.

what is the OA product called at walmart?
