I'm still kind of experimenting with that. This is the third frame I've used it on, and I'm doing less each time. This time as an experiment I scuffed the top tube up quickly with some coarse sandpaper, but didn't touch the down tube or head tube. As you can see, the sanding wasn't necessary in this case. I have a theory that there is some correlation between how well the paint bonded to the frame and how much prep is needed. On my 1973 Nishiki, the paint on the frame softened but didn't blister like this, but on the fork it blistered easily. This stuff takes paint off of chrome like it wasn't even stuck on there to begin with.

For the second picture earlier I just wiped it off with a shop rag -- nothing abrasive. I put on a second coat this morning and got most of the places I missed last night. After wiping with shop rags again, I went over it with a dry Scrub Daddy sponge, and that took most of what was left.


I discovered tonight one embarrassing thing tonight. The paint on the drive side chain stay just wasn't coming off at all -- not even a bubble. Then I scraped at it a bit with a plastic putty knife and that didn't scratch it. Can you guess why? Yeah, there was a clear stick-on chain stay protector. You can even see it in one of the pictures I posted yesterday. I didn't notice it.

When it's nearly done I'll use a wire brush on a Dremel tool to clean up the tight spots and anything else that's still there. It looks like I'm only going to need to sand to get rid of the rust and prep the surface for primer.

That’s good to see work. I like keeping toxic chemicals to a minimum..

I managed to squeeze in some time on my Peugeot project in the last few days. Here’s the as found pic again:



Cost to me was $50, and I’ve sold off the pump, saddle, hubs, and brakeset for $126, so I guess I have a $76 credit (plus a $108 budget? Not quite sure how the accounting works). I had to drill out the cotters, unfortunately:



But otherwise the frame cleaned up reasonably well:






Current build concept is a single speed porteur with 27” wheels, coaster brake and front rack. I’ll likely re-use the BB and crank arms with single alloy ring. I have a rim and rear hub on order.

Dang, you guys have vision...!

Very nice weather today so got some more work done on the Motive. Turns out the tires were bad looked good but failed after about five miles so replaced them with used junk set of Kendas and patched tubes and put on nice used 7 speed freewheel from my parts bin so figure another $25 so I'm pretty much at budget about $100 total. So it looks like other than some additional cleanup and service I'm will be going going with a single speed/screw driver gear change for this one and will just have to he-man 90 miles or so on back roads and dirt trails to complete the challenge. Bike actually rides pretty good and the frame is nice so ounce the challenge is done good chance I will put a proper 8 or 9 speed drive train on the bike.Did get a short ride into town to the library for another 5 miles or so.

That sounds so much nicer than telling me that I'm hallucinating.

I'm hitting a wall here. Attempting to build a front wheel is going to send this project in a different direction. I have hubs, rims some spokes and a fork that do not fit neatly together in my Venn diagram.

The difficulty stems (no pun intended), from the fork being spaced to 90mm. I really think that attempting to spread it 10mm would be pushing it too far. I have a rim that I'd like to use that has an ERD of 584, and a hub that I could lace it to that is made for 90mm. The problem is that the spokes need to be 285mm - which is out of stock here. Alternative 2 would seem to be replacing the fork, which has a 1" diameter steerer that is 5-3/4" long... which is also out of stock.

Sooo... Plan C involves compromising on the wheelset entirely and going with what I pilfered from a Ladies' 1970 Raleigh Sports that I picked up in a thrift store in Bellvue, KY about 5 years back for $20.00. The wheels are chromed steel, heavy, and there's no way I'll be able to remove every single hint of rust that long-ago set in beneath the rim strips, but the rear is a 3-speed coaster brake, the rim diameter matches that of those Kurt sent me, they spin pretty well, and even if I can't get them any truer, they're not too far out. One way or another, those yellow fenders are going on this baby, and at some point beyond the challenge the wheels are going to change.

Looks like it should be tethered to a hitching post.

I rode over 1000 miles last summer easy on a 1973 Huffy Scout I paid $3 for at a garage-sale in the spring. I put $5 worth of used tires on it, about $6 worth of new brake pads and maybe $3 worth of new spokes. Also put a new chain on it that was surprisingly cheap at about $7. So that is $24. I did spend time cleaning and lubing the moving parts of the bike,bearings, lubed the cables etc.. Trued the wheels of course. the only part I replaced besides the tires was I swapped another old seat onto it because the seat I got with it was missing large chunks of it's cover and padding so half the metal pan was showing and it would have hurt my butt. I even played with the old combination lock on the bike until I cracked it's code and used it. I am sure I will put hundreds of more miles on it this year. Is this the type of bike this thread had in mind?

Clang

Yes. With the Clunker Challenge you get points for lucky scores on nice bikes, but you also get credit for riding total garbage.

What's wrong with this one? That spoke protector...

Andy_K 

It goes nicely with the bash guard on the crank.

I (more or less) finished stripping the paint from the frame on the Centurion.





It frees the rust to express itself without the distraction of the surrounding paint. Next, it was on to the fork.







Tonight I've been working on sanding the rust off of the frame. That's a very satisfying process. It's just about done, but I'm going to leave it until tomorrow to take pictures of that.

Sure

The weather is finally nice.

I’ve never see a BB-CS20 before. I came out of my Schwinn Impact Pro easily which is a plus. It is not real crunchy but it does bind every couple of rotations in the hand. I removed the seals, dripped in some Liquid Wrench followed by 3-in-1 for no noticeable improvement. The sockets required for adjusting must come in the same set as those required to adjust PD-M324 pedals. Cool thing is that when I reinstalled the BB and put on the cranks, it spun A-OK.

It rubs the Citri-strip on it's skin!

First ride of the year, 14 miles done. Getting better with the dt shifters.

at the Redwall castle. Took me a while to find it.

Seat could be raised some. I tried to remove the stem spacers last night but they are stuck. Could do without the pedal reflectors, "dork disk" and kickstand.

Well, I unwrapped the mummified in Evapo-Rust-soaked cloth LeTour to find ... very little difference. Certainly not photographable - but it feels slightly less crusty. I think some sandpaper is in the bike's future, but I've talked myself out of repainting it. I hope to find some time this weekend to do some more cleaning, and then begin repacking and reassembling the bike.

I'll be interested in seeing what the brake lever hoods are like under the electrician's tape. I actually have a set of suitable hoods I pulled off the mismatched levers that came on last year's first Clunker Challenge entry, the '86 Cannondale - but they, along with the pedals I think I want to use, are at the back of the storage unit, and probably in the bottom box of the stack. I'll probably spend as much time getting to them and then putting everything back as I'll need to repack all the bearings.

I'm amused when I remind myself I will probably spend more on a set of decent tires for this project than on everything else involved!

No pix today - maybe later ...

This is easily my favorite comment of the thread so far.

What makes a bike total garbage?

beng1

I don't understand how all the photos of my yellow bike ended up here. Yesterday when I tried to upload them it said I could not do it unless I had more posts or something, then today I log in and take a look at the thread and there they are. These computers are sure a double-edged sword.

Clang

Here's something from the first thread that spring to mind: a literal dumpstered bike with a chain rusted into a rigid zig-zag pattern and Pacific Northwest moss sprouting on it.

\ Hard to say but for starters if you got it out of a dunbster or trash sure yet... Pretty much got eliminated in the challenge prior yearsr for bikes that were too good. My last entry a trash bin find Schwinn Mesa GSX just was great but didn't really hit the meaning of the challenge

I own it….
