My favorite seized seatpost story; 24 hour soak with WD40. Bike was stripped of most other parts, but BB and cranks were in still. Seatpost was decided to be a throwaway and got clamped into a bench vice. Heavy action on the post with a propane torch, a little bit on the frame, too. Two mechanics grab the frame and start levering on it. It starts moving. Slowly at first, then slowly all the way to the end. There was a lot of friction. When the post finally came free, and oxygen reached the superheated WD40, a 16 inch jet of flame shot out of the seat tube. It was glorious. I would use the same technique again, but just pull the BB to prevent a "framethrower" incident.

[@oldshovel]

Awesome story 🙌

[@murphykenji]

"Framethrower" is an amazingly good misuse of the english language. 😂

[@kristiandawe85]

I love that Calvin Jones from Park Tool is in this video

[@emlyndewar]

Had similar on a used old frame several years back and saw a forum post advising to use caustic soda as it just eats aluminium. I left it a few hours and there was nothing remaining of the post in the morning. Was great, as had been tearing my hair out. Heat and large amounts of penetrating fluid did nothing.

[@ethanjack4298]

I've also done this with a stem to great success.

[@dumpkingbikes405]

Been there, tried all that. Chemistry works the best!

[@cccpkingu]

Disposing of or neutralizing caustic soda seems easier than to get rid of gallium.

Gallium ... what a great Idea. I have a 1993 Marin Bear Valley SE in my Barn .. Nowadays totally stripped for Parts but with a Setpost that Stuck even the Frame is sucked on like Shrink Tube. I never won't to let it go and throw it away. Now i know a new Route to go. Thanks alot

[@oldshovel]

It takes more work than it looks like in the video but it did work. The Gallic process took most of a day, letting it sit for a couple hours between “soakings” and chipping. Good luck.

Awesome new life given to that sweet old bike... The floor of the Old Shovel shop must be its own work of art from the blending of all the cool paint colors you've used for the rebuilds over the years...

[@oldshovel]

Lol actually one thing I like about the spray.bike paint is that it drys to a powder about 18 inches out of the can (ideal spray distance is less than 6”. So after a paint job I just sweep up.

[@scottenglert4083]

@@oldshovel Whoa that's really cool - never knew that could be a characteristic of a paint that could also be resilient enough to use on a bike frame... I've learned lots from this video !

[@jerrys.projects]

I found blow torches to work best. They tend to heat up the seat post way more than a heat gun and bbs, seatposts or forks come out so quickly and easily. I`ve been giving up on my favourite frame, rode it with a stuck bottom bracket and I've been so happy the day I finally got it out - without any harm and sweat - just by the use of a blow torch.

[@martimcfly6207]

I did that as well. It worked fine. But it was an aluminium fame. Since the temperature coefficient of aluminium (frame) and steel (bottom bracket) are largely different, the frame will expand more. Hence the BB will become lose. With steel on steel, or even an aluminium seat post in a steel frame that probably does not work.

[@jerrys.projects]

@@martimcfly6207 In my case: It did. I think all these approaches really contain some luck in every case. :)

[@martimcfly6207]

@@jerrys.projects good to hear. Maybe the expanding and shrinking also helps to loosen the bond between steel and steel. If it works, it works

[@raulelumano7902]

You had to apply the good old alchemy to disolve that seatpost, uh? Amazing determination.

[@mountainsmoore3657]

Awesome video and awesome opportunities for you, man! I mean, it's every bike geek's secret dream to get to travel to new places, work alongside Calvin & Truman, show off your work to the guy that is responsible for the bike being manufactured in the first place, and then present it to a non-profit back home as a fundraiser. Okay, well maybe ALL of that isn't every bike geek's secret dream, because who could've dreamt all of that up for one sub-20 minute video??? Another cool bike build and another great job of documenting it.

[@jeremy5393]

[@graememorrison333]

After trying everything else bar the blowtorch, I had to get similarly mediaeval on a campag chorus carbon post which had welded itself into a very expensive carbon frame. Thankfully it worked and with no (apparent) damage.

[@joaobikes]

Belíssima bike. É parabéns pela sua ajuda no trabalho comunitário. Projetos como esse são ainda mais importantes. Obrigado e continue sempre seu trabalho artístico

[@Flako-dd]

for aluminum/steel galvanic corrosion i always go pretty quickly to the reciprocating saw and cut the top then the inside. It is usually the only way since it is almost like it's welded. Puts less stress on the frame you just have to be careful to only cut the seatpost.

[@desohara7466]

Love your videos Sir! All done for the love of cycling. Keep up the great work!

[@garysprojects]

Wowww! That seat post was a really stuck in there, glad you got it out. I thought mine was stuck but it was no where near as bad as yours!! Great to see it saved ! I was surprised how light the frame was all the welds/joins were spot on. Fat chance makes great bikes. Nice work on the resto 👍

Thanks my friend. It was a rough one to get out. I’ve had some bad ones but not this bad. 🙌

[@michaelsnedden9029]

I was having flashbacks to my past adventures and disasters with stuck seat posts.

[@sagehiker]

Think you might test the seat post first before picking a bike out? Watching Spindatt last year scared me and a lifetime as an industrial mechanic have me leary of extra wrenching and heating. Great work for a fantastic organization. Rather than collect the big parts bin, your channel has inspired me to pass on working spares and take-offs to Boulder area coop since I don’t have one in my area.

[@jjonsolomon]

Oh boy. Right after graduation I worked at an engineering college. I purchased a bike from the police auction with a stuck post like that. I worked an hour a day in the machine shop with a drill and a rat tail file. It took 3 weeks to get that seat post out. When I was done the machinist asked how much a bike without a stuck post would have been. Good learning discussions were had

[@tonydejesus2134]

Wow, I feel you man. I had a stubborn seatpost last year I had to take a blowtorch to.

[@curtislee6242]

Been there, done that. It took me weeks to get it out. The alloy had fused with the steel frame. I had to saw and chisel it out. There's still a bit left in the frame. So much pain.

[@hramsay8756]

After stripping the bottom bracket, invert the bicycle. Fill the seat tube with Oxalic Acid. Let it sit in a well-ventilated area for ten days. Drain the acid out and rinse the bicycle with water. The acid dissolves the chemical bond between the steel frame and the aluminum seat post.

[@blue3549]

beautiful vintage Fat Chance, love the way it turned out

[@oldshovel]

Thanks

[@Gabbro.88]

Buona Pasqua 🐣

[@coletrick8748]

I’ve removed no less than a dozen severely stuck posts. Lay the frame on the ground flat (on grass), take the pipe wrench and put a pipe on it for leverage, stand on the frame and push down with leverage.. I use a four foot pipe for leverage. Sometimes I’ll have someone stand on the frame so I can concentrate on the pipe wrench.

[@stever2726]

Adding to all the others who've shared ideas... I had a stuck carbon fiber post in an aluminum frame. There had been a chemical reaction that bonded both in place really tightly. I used citric acid drops around the insert point to soak/seap down into the spaces around the seatpost inside the frame. That helped break the chemical bond. Then I used repeated rounds of nearly boiling hot water over the seat tube to create a gentle expansion of the aluminum. After a lot of that and multiple rounds of trying to wiggle the post, it finally broke free after like 45 minutes. I was able to save the frame and not damage the paint with a torch while still doing the job of adding the necessary heat. The seatpost came out in one piece too.

[@oldshovel]

Interesting. I haven’t heard of that technique.

[@stever2726]

@@oldshovel Thanks! I can't take credit for it. I found it searching online. Some engineer type who loves to wrench explained that it has something to do with the two different types of materials and how they both oxidize. I'd been using citric acid to remove rust oxidation on bike parts, so figured it was worth a try. Lo and behold, it worked great! Thanks for all your great videos!

My Cannondale F1000 had a snapped seatpost when I bought it (got it ridiculously cheap b'cos of this) .. but it was just below (like 1-2 mm) the seat-tube opening.. 05:57.. this looks VERY similar!.. I had MONTHS of messing around..trying not to damage the frame.. I got hold of one of those "single sided" hacksaws.. Padsaw i think its called.. and started gently sawing away.. cut out 2 lines opposite each other till i was close to the frame.. then just swapped sides after a few "saws" and POOF..or POP..out it flew.. hardest thing I've ever had to fix on a bike..it wasn't going ANYWHERE..litterally snapped on the other fella who tried to get it moving..thing was STUCK!.. it's starting to come together now though.. I ADORE this frame tbh.

I don't know if I should change spokes... not rusty at all)

[@Caseya1980]

If you take a can of duster spray and hold it upside down while spraying it will instantly freeze anything in front of it . I would try heating the steel seat tube as you did then freezing the inside of the seat post next time . Just a thought , love your videos .

Great vid. I was "listening" to the banging as I was trying to remove a wire-bead 30tpi tire from a MTB wheel to convert to tubeless...bead was able to get a perfect lock between the J hook and the rim tape and would not budge...ended up separating one side with a vice, and the other only came out after I destroyed and pulled out the rim tape to creat that much tiny of space...two wheels, took about 2 hours before I decided that something had to be sacrificed. No Rims, Inner Tubes or Tires were destroyed in the making of all these sweaty spots.

Graet idea with the Gallium. When I was in this situation i used sodium hydroxide solution which solves aluminum but not steal, and it is more accessible than pure Gallium.

[@barthanes1]

Wow, a gallium removal. Haven't seen that one before. 👍

[@keithschrack]

Gallium...what a concept! I know that lye will do a similar number on aluminum posts, without harming the steel. Been in the same situation and I really hate it when an otherwise good post has to be sacrificed. It leaves me feeling defeated.

[@ToddNZMTB]

Is that what that stuff was?! Seemed to work, I've not seen that method before!

[@komoonkh]

Yeah, Gallium. Spindatt Eric did a video about that. It is better than lye, because it wont destroy the paint. But it is kinda expensive, if you can get it at all.

[@keithschrack]

Me neither. But, as soon as I saw the vial, I knew what he was up to. It's a strange molecular reaction that causes solid aluminum to become crumbly. The whole idea is inspired! DON'T use it anywhere near an aluminum frame, though!

[@oldshovel]

Yep I saw Eric Spinny do it and tried it out.

[@abandoneduniverses]

Ι use diesel injected with the frame upsidedown from the bb straight to the seat tube.leave it for a night or so..and if still resist drill the seat post to insert horizontally a long lever in hole and turn...its always working..regards from a vintage mtb collector from far away Greece

[@hotrodjoey50jo]

When I have one that stuck I take the seat post water bottle cage bolts out, turn the frame upside down, then soak the inside of the seat post tube overnight with your favoeite penetrating oil. then, clamp a pipe wrench in your vise THEN hook your seat post in the wrench and twist the frame. also, would help a lot if you could get your vise bolted down solid. GREAT video as always - good work sir
