Finally riding a big boys bike
What is the best tool to remove headbadge rivets from the inside of the headtube without damaging the rivet or prying the headbadge? I thought about getting one of those tack pullers behind the badge and around the rivet, but i dont want to bend the badge. What kind of tool is used for pressing rivets that are deep inside a tube? I would like something like that to press from the inside.

Not helpful. I'm looking for serious answers and practical advice, not satire.
 
I use a solid steel rod about 3/8" to 1/2" in diameter. Insert it into the head tube and position the edge of the rod against the back of the rivet. Then use the end of the head tube as the fulcrum and gently lever the rod to press the rivet straight out. This applies pressure directly to the rivet from the inside without prying against the headbadge itself, which helps avoid bending or damaging the badge.
 
There just isn't one tool made for this job.

Use the largest diameter rod you have that will fit inside headtube or cup, insert just to meet the edge of the rivet tail, then lift and push to other edge of rivet, pry against opposite side of headtube or cup to push the tail of the rivet out and flush with the inside of the headtube. I think even a seatpost will work for this step, 1-1/8" solid rod probably works best. Next, I use a cotter pin extractor, find the center of the twist rivet with the pointy L shaped end of the cotter pin extractor and pry in the same fashion as the rod. The pointy tip is usually enough to push the rivet all the way out, so be prepared to catch the shooting rivet! Finding the center of the rivet tail and staying on it is the hardest part. Not all cotter pin extractors are created equal either, so you may need to add a flat shim behind the bent part of the tool for better leverage against the inside of the headtube. Some rivets are tough too and you may have to tap the top of the cotter pin extractor with a hammer. Holding on to the shim, extractor, and hammer while catching the rivet can be quite the juggling act...so, a piece of masking tape over the front of the rivet comes in handy to keep it from flying.

This is helpful advice, I'll try that, thanks. I guess more what i was wondering is, what tool is used in manufacturing when pressing a tubular rivet into the middle of a long tube? Say you need to rivet something three feet into a tube, how do they do that? There has to be some tool that reaches far into a tube to press the rivet from the inside. I'm talking tubular rivets, where it needs to mushroom out on the inside to attach, i figure a tool for installing those that can reach really far into a tube would work great, but i dont know what that tool would look like or what its called or if it even exists to search for it.
 
Terminology is important when talking about fasteners ...
The fastener for head badges is NOT a rivet it is called a Hammer Drive Screw or U Drive Screw.
Tubular Rivets come in solid or hallow and the tool name is a Rivet Squeezer, they come in different depths to accommodate what you are looking to achieve.
