Teardrops n Tiny Travel Trailers

Dear All,

I am still demolishing the teardrop4vets frame. I came across a type of fastener I know nothing about and have to remove quickly.

It is sort of a rolled up piece of metal used in a similar way to a cotter pin.


connects a rod inside a tube.

How do I get it out?

Can you tell if it has a split? If so, you should be able to drive it out with a punch or something similar. It is probably just a compression type pin and can be driven out.

It is a coiled spring pin. Looks like I can bang it thru but I do not know if that is proper

...like TP said, it sounds like a basic "split pin"...it should just drive out with a punch, small drift pin or whatever you have on hand

It is a roll pin. Made of hardened spring steel. You can’t dill it out with out breaking the drill bit. You have to use a punch just a little smaller than the hole the pin is in. If the punch is to small it will go inside the pin and wedge the punch in the pin or break off.
If the punch breaks off you are in trouble. The only thing you can do is use lot of heat to try to take the hardness out of the pin and broken punch and try it again. If what is left is not damaged from the heat.

Guy, it sounds like it's a coiled roll pin and probably looks like this.

Like everyone said, it will just drive out but it's too hard to drill out. If it's rusted in place I sometimes heat things quite hot then put cold water on them. A lot of times it will break loose enough to finish the job with a BFH.

Thank you guys.

I wondered if there was a special tool to do the job, but guess not.

Actually I do recall seeing spcial punches for roll pins. They had a sholder to catch the edges of the pin with a short mandrel that fit inside to keep the punch centered. Even if you could find such punches you would have to find one just the right size for your application. I've had good luck driving them flush with a brass drift to prevent deforming the end then finishing up with a punch just smaller than the hole in which the pin fits. Main goal is to not deform the end of the pin that you are driving through the hole (you only get two chances).

Oh and as someone already mentioned a BFH could be useful too.

The special tool is called a "pin punch". It's just a round, flat ended punch of a slightly smaller diameter than the hole.

Just when you thought it was safe to go back to work along comes the Google fairy and you find out about a "Rolled pin punch"

The punch you describe is the one I recomended using. But the roll pin punch I mentioned is a bit different than a standard pin punch. Either will work if used properly.
