Tension Pin Help - Woodworking Talk

Rookie q here- but does anyone have any tips for inserting a tension pin. It is going at an angle from one side of a hub, through an axle, and out the other side of the hub. I'm not sure how to compress it enough to insert it into the axle. The hole in the axle was drilled for one-eighth and the pin is the same size. Thanks!

I'm not sure of what your are asking, I only think I do. Can you be more specific?

What I have is a spinning wheel- here's a pic of the wheel with the old pin.
I'm just trying to replace that pin as it was bent. The hole is the correct size, but I'm having trouble putting a tension pin in through the hole where the old one was.

Are you talking about a kotter pin. (A split pin.)

You may have to file a point of the front.

I'm at work and for some reason, I can see some pictures and not others. Apparently they get blocked. Whenever this happens, I seem to be the only one that don't see the photo.
I hate to guess not being able to see. Usually it requires some kind of lubricant like Vasoline. I would not use it or any other oils unless the spinning wheel was already stained and finished. Sometimes you can use bar clamps to push one pin out and the other one in. Sorry I can't be of more help.
Hopefully someone else will be able to help

Another thought. Put the pin in an electric drill. Hold some sandpaper in your hand and fold it around the pin. Turn on the drill and sand a small taper on to it. Be careful because the sandpaper will get hot from the friction of the spinning pin inside it.

Thanks for the help- I will try the vasoline and if that doesn't work I will try to make a small taper on the end to get it through the hole in the axle-
GeorgeC- it isn't a cotter pin- it's one piece with a split in it- I think I've seen them called spring pins or roll pins also
TonyB- maybe it's flickr that gets blocked, but here's the URL to the pic- it just shows the old pin that I was trying to take out, but it would give an idea as to where I'm putting the new one
here's the URL

I'm offshore on a platform in the Gulf of Mex. This particular platform has blocks on almost everything. I not only cant get U-tube, I cant even download news videos from Yahoo or Msnbc.
Anyway, I have a good idea of what you are trying to do now that you said spring pin or roll pin. I think that if you just lay the sandpaper on a table and put the pin in a drill and hold it on a small angle off of 90* and make a chamfer instead of a longer taper it should work. If that dont work, try it with the chamfer and Vasoline.
You might want to use a bar clamp around the whole thing and slowly use cranking pressure to ease the pin into place.
If That dont work, try using the private message on here with an 'attachment' photo.
