Seat post removal tool...

[WillWork4Parts]

The tool frame is attached to the crank spindle. And it does sound like someone is hammering until the very end where it's a fast repeat hammering noise.

The guy's Instagram account shows the tool a little better.

Wish they would have had a zoomed out view to show the handle being turned, the post moving, and then zooming in on where the sound is coming from. It's the post popping loose/chattering making that sound...like if you've ever used a press to remove a drum brake or cylinder.

Here is an older video with a different fabricated tool.

This tool is pretty sleek, but uses the same principle of drilling a hole in the seat post. I'm not a fan as I've seen too many rip through that hole. Plus, that's the reason I usually end up working with a mangled stump only sticking up about an inch above the seat mast.

This hack... doesn't even look like more than a pair of gloves would have been required to remove the post. Looks like a good way to do damage or get yourself hurt though!

It's good to have different ideas before you start fabricating though. Eyeballs the "Little Brute"

Here a few more examples of some Hillbilly version$.
As mentioned, I have never witnessed any brute force of this magnitude for this specific purpose.

That rig is stout! I agree, the clamp may be lacking in needed surface area, the height that one is sitting at, you could add plenty more clamps though. The sound it is making, it's doing some significant work.

Geez, makes you wonder if this would work on stuck handle bar stems as well. Quite the contraption I must say. Cool, cool COOL Machine you have there.

Interesting idea. I think I'd have to see it in action more before I'd buy something involved or expensive. I don't pull enough stuck seat posts to make something expensive worthwhile. I'm not a big fan of repeated hammering because it shakes everything loose on the bike, and I suppose could crack a seat mast joint on brazed frames.

The last one I pulled - cut off the seat post top, insert and tighten a quill stem inside the cut-off post, use a set of old handlebars in the stem as leverage to twist and pull the post out. No hammering needed. There was enough post above the frame that I didn't need to go down into the frame with the stem wedge. I believe the post was just plain stuck, not chemically welded into place (at least no signs of

Honorable Sir Mike, that is a great idea. I have a stuck seatpost on an old Murray that is jammed into the tube, with not enough stem to really get ahold of it to pull. Using a quill stem seems like it will be perfect. But the top of the post that is showing is sort of oval shaped, like it was squeezed. So it's stuck. But this should work...with some P Blaster, of course. Here are some pics. It's a Murray Westport...26 inch. Found next to a dumpster. Bearings are all good. I'm just going to clean and preserve it, with a vintage leather saddle and cream tires, for an old board track look.

Thanks for the link. I love the come-along method, and how the pull is exactly linear down to the bottom bracket. Ingenious.

Stems are a different ballgame, but some adaptations could be made to use the same puller probably. It's got me thinking about a shorter tool that would sit on top of the seat tube. Using just that thin lip might have some slipping off issues if the tube edge has been mangled by the seatpost clamp or other tooling. The top nut of the headset would have to be there to protect the threads while removing the stem. It would be nice to be able to twist the stem or post too.

RJ the bike guy is the one that actually developed the first prototype of this tool. Its interesting to watch him in his quest to develop a solution for this problem. You can check it out at:

This is what Ive used..Ive clamped it onto the seatpost and used the part of the stem that normally goes into the fork as the "handle" so I can work the post back and forth.as trying to use something like vice grips are about useless ..Of course,use lube and heat also

I CAN hijack my own thread.
I found this grassroots bike mechanic worthy of my attention and wanted to share with the like minded.
@BikeFarmer keep'n it REAL.

Inspired by Bob Ross, the BikeFarmer videos are more of a 'Watch Me Work' style than a 'How To Fix Bikes" channel, the BikeFarmer videos will follow lifelong shop owner and mechanic, Andy Q as he works through bicycle projects, mostly refurbishing used bikes for resale, but also anything related...

I've watched a few of his videos. Saw the one the other day where he said he's closing the shop to the public essentially and only working on what he feels like as content for the channel. I don't always agree with the way he does things, but I think that's the point of him doing what he does. I do enjoy a bit of that attitude. Lol
I've never necessarily been directly for hire either, but I like taking on the interesting projects that standard bike shops don't know how to do anymore or don't have the parts inventory for...the things that keep the vintage cycle hobby rolling!
I fully support the stance about how most people are narrow mindedly led to believe that the only way to enjoy yourself on a bike is to lay down $1000+ for a NEW bike, then buy all of the appropriate gear, take riding courses, etcetera, when all you Really need is a bike, not purchased from Walmart or Temu, to get out on and immediately start enjoying yourself....you may likely even have more fun on a budget bike!
