Removing Stuck Seatpost With Homemade Seatpost Puller Tool - Test 2 - Success!!!

Working on designing and building a tool to remove seized/frozen seatposts. This is my second version, and it was a success! This is an aluminum seat post stuck in a steel frame via galvanic corrosion. I also tried heat while the seat post was under pressure, which didn't do anything. FYI, the threads on the threaded rod were greased with marine grease.
Here is the first attempt:

Cut the end of the post down weld a large nut to the end then use a heavy slide hammer on it while the frame is securely held in soft jaws of vice. Nothing beats impact for removing stuck parts.

[@musicomarc6129]

Truely inspiring. Your sense of innovation, patience and resilience is unmatched. Thank you RJ.

[@dirtnastyish]

It's always so satisfying when a stuck seat post finally comes out.

[@rharro9482]

Awesome! As someone who has battled and lost to more than one frozen seatpost I am totally digging this thread. Thank you for the inspiration!

[@trekkie9942]

Yeah! That is a fricking satisfying sound! Great job RJ! I bet Park Tool will be coming out with a design like this one any day now! LOL.

Nice! that first pop sounded like the bottom bracket had cracked...very ingenuous idea RJ...

[@RJTheBikeGuy]

Just the seatpost moving a little.

[@Nellyofmoonchild29]

Awesome videos, and even more awesome tools by the master mind him self, RJ The Bike Guy. You need to patent that tool ASAP.

[@longrodlseries]

Oh man I just made a tool like yours and then my friend said to check out your video. The tool works! I do agree adding a handle would help for control and safety. I do like yours in that it is very heavy duty and the extractor section that connects to the seatpost is nice or what I need to build. Hearing the pop was victory!

[@tomroeber4861]

Thanks for the video. I had the same problem with the seat post, but no welder. I broke the seat post off just above the frame while trying various methods. I was able to grind down the diameter of some 1/2 inch washers, then slid them up the seat tube and engaged a nut into a length of allthread to catch under the seat post. I added the weight from a slide hammer over the allthread, then added washers and a nut for the stop. Worked great with less effort than I expected. I also had to drill out a couple of rivnuts for the bottle cage to get the washers past, but luckily you also have a video on installing those. Maybe Park could make some plugs with an ID thread and a cutout to clear the rivnuts. A few different sizes for different seat tube diameters. Keep up the good work.

[@dirtyshirtinfo]

Fascinating. Loved the multiple booms as it let go. I wasn't expecting that. The whole time I was wondering about frame damage..props for examining that at the end.

[@thedailycyclist9295]

That was so satisfying hearing it pop! Great job RJ, love your homemade tools. Still use the one to remove stuck BB cups that you showed us how to make.

[@ebi3141]

Great simple and robust design. Look forward to seeing future testing.

[@bryanmartinez5960]

Nice job on the seat post extraction tool! May wish to grease the threaded shaft to prevent galling and at the base of the nut/washer to reduce friction. A hardened grade 8 washer, or 2, will also make it easier to tighten. The In addition, once tension is applied to the shaft a few raps with a hammer may facilitate release of the stuck post. Where are you located I have a few stuck posts...?

[@davemitcheson4210]

I’m sure I’m not the only viewer to shout “GET IN YOU BEAUTY” when you got it it out. Top work, as always, RJ.

[@anzaborrego399]

Just amazing how resistant the stuck seat post was. Thanks!

[@yv5grb]

I like those DIY tools... Your brain is working! Thanks for sharing

Park Tools ain't got nothing on RJ........RJ makes the tool that makes the tool to do the job.

[@MrWeky12]

THIS IS AWESOME RJ!

[@celynjones4958]

Love it. When I was a kid I rode my Raleigh Ultra Burner through the local river. After the seatpost welded itself. My dad tried heating, wrenching, wd40, hammering etc. It didn't budge. Had to scrap the bike. Your contraption would have been a life saver. Cheers you've earned yourself a new subscriber.

[@galaxion62]

This geezer did a great job in making that extraction puller tool. If worried about the possibility of threads stripping, always use a finer threat to alleviate the risk. Great video, & safe methodology adopted here.

[@laurentiussoepomo7747]

The tool you make is just work well. Amazing.

[@johnpossum556]

If you are worried about the galling on that washer replace it with a drilled piece of the steel tube. If you want the closest fit you sneak up to it with an adjustable mechanical reamer. Cool tool, reminds me of things I've made for various automotive work. On the technique I would first use your tool to push it in before trying to remove it. I have better luck with this technique on seized joints. It doesn't need to be much. I'll share with you the best of the best techniques I know of from a mechanical guy who could do anything. ( He welded a hand trike up for his paralyzed son. Coolest thing I ever saw as a kid! ) You heat the joint then pull it away and apply beeswax (toilet bowl gaskets are a cheap source) and it sucks it right in there and acts like a lubricant and its amazing how well it works on rust (our state uses salt so we become experts on this while working on our vehicles). If you ever do rebuild it consider using something like an air chisel to vibrate that joint out of there. They can handle things that it normally takes a full out machine shop type hydraulic press to remove. Last note: I wouldn't try pulling on that extension of the seat post for two reasons: A) It's the obvious weak spot because it does a 90 right there B) If you look closely you see a line down the middle of it which is proof that it is casted metal. While casted metal is very strong it is also very brittle and when brittle metal breaks it is often razor sharp. It's just not worth the risk to your own body by a sharp piece of metal alloy when a seat post is basically a cheap item. Also that seized dark spot is a likely place for tetanus to reside. I've been told by ER folk (when getting evaluated for getting a tetanus shot because I couldn't get them for other medical reasons) if the metal is fresh its rarely a risk but metal that has been sitting around for a long time in the rust is more likely to have it.

Awesome video RJ!

[@waldameerrocks0258]

So me and my dad got my seat post out and found out that someone had cut the seat post down to fit them on a xl frame. Which made it extremely hard to get out. With some cursing and swearing plus pb blaster and a blow torch we got it out. It literally had a 6 inch post and we were baffled at the bike I had gotten for free. I'm glad that we had a steel pipe that was the exact diameter of my seat post because when we went to use a port a power the seat mount that was apparently glued in with some sort of glue popped out and we popped the part into the new steel pipe. Thank you for your videos and support on how to and diy repairs!

[@bmolendijk7884]

Haha, great! this tool is awesome! cool thinking. I have 3 steel bikes with aluminium seatpost, after seeing this video, i immediately checked if none of those where bonding, luckily not, used enough grease for now! cool video, thumbs up!

[@meadows408]

Nice job. Never underestimate a man with a spiral inclined plane...or a dremel tool. Keep the videos coming. And I wouldn't worry about the washer, just replace with each use.

[@jimmylovesbikes]

Soooo satisfying. Great job!!!

Maybe weld a washer to the coupler... I think it will be better than replacing it with a larger nut.

[@username-rd8cl]

I think this would work with some type of clamp surrounding the post. And in the front steel fork as well for pulling a stuck quill also. Just in case you want to save the part like in some classic old steel bikes. Brilliant design I must say, RJ.

[@sambananas4513]

Excellent video, a true inspiration. I think you could either aluminum braze or tig weld an aluminum plug into that hole, and reuse that post.

[@benspeedschannel888]

Fantastic job!

[@tad2ik]

Congratulations! This is the tool for for the job! I spent days fiddling with spanners, blowtorches and hammers to extract one seized seatpost. I would have been quicker building that tool and removing the seatpost even if it was just for one time. By the way you could put a flat ball bearing under top nut to reduce draging

[@grg613]

That's a brilliant idea. I'm happy you mentioned the plan for a handle because I was really concerned the threaded rod would snap while your fingers were less than an inch away.

[@RJTheBikeGuy]

I wasn't worried about the 5/8" rod snapping. More likely one of the 3/8" bolts. Or possibly the threaded rod stripping out the threads.

[@j.s.k.7746]

That’s excellent. I wish I could weld one up!

[@ninjaspam2000]

use a thrust bearing under the washer. That will help reduce the friction when tightening

[@RJTheBikeGuy]

The newest design has one. But I haven't had a chance to try it yet.

[@PhaseP1]

@@RJTheBikeGuy And good amount of oil or grease on the threads and where the nut presses on the washer/or bearing. Want to minimize the friction as much as possible with that much force on those, similar to automotive puller tools usage.

[@RJTheBikeGuy]

@@PhaseP1 It was greased.

[@wesleywashoe8029]

This a really cool tool you made, a high lift jack works the same way just invert the frame in a pro park professional bike stand and reverse the jack rathchet cranking it down while standing on the heavy steel plate.WD40 RUST REMOVAL is what i use to eat thru the corrosion.

[@ajslug]

Great job!! I cheated when I needed to get a post out. I made a solution of lye. It worked really well. I protected the paint by using rubber corks on all the frame tubes (inside and out), taped a home made funnel to the seatpost opening, then covered the entire frame with plastic drop sheeting, kept a loaded garden hose at my side.

[@doylerabjohn9057]

The position of your left hand while you are cranking on that is giving me the heebie jeebies!

[@tonyparrish5566]

Awesome idea! As for the last part, any time I've tried applying force to the head of the seatpost, it just pops the head off. I'd stick to drilling the post itself.

[@batbawls]

I have to admit that I wouldn't have the balls to try this twice, as it reminds me of trying to compress coil springs from a auto suspension. This was awesome nonetheless!

[@tedoyle61]

The absolute in seat post removal technolgy!

[@yerit4me]

I have made a lot of special pullers and I found that if you use a full cage roller bearing (a small rear axle outer bearing for a rear wheel drive car) it's much easier to turn the nut. Yes also put a extension in the top square stock for safety if anything breaks on the clamping assembly you don't want your hands down there.. 🤗
