Welding vs. Tapping vs. Roll Pin
I want to permanently attach 3/8" diameter rods to 3/8" rods end-to-end and was looking for advice on the best way to accomplish this. The methods I'm considering are welding, tapping, or use of a roll pin.
The rods will only be about 3-1/2" long, and the pieces that I want to attach are 1/2" long. Perhaps a combination of the attachment methods mentioned for this rod extension project would be warranted. Any advice would be appreciated. Thanks. Darren Harris Staten Island, New York. |

That sounds like an easy lathe job. Do you have one? |

How much force will be on the extension?

I think there must be a lot you have not mentioned. Otherwise you would just use a longer rod to begin with and not have to do any attaching. Dan |

Yes, I have a lathe. What I don't have and was looking into getting is some welding equipment. (I have a little MIG welding experience from back in the early 80s).

As I recall he lives in the city and has limited space for machines. Repairs old arcade games like pinball machines :) -- Leon Fisk Grand Rapids MI Nah, I stay away from Pinball machines. This is actually another video game related project. You know the standard ball-top video game joystick? I plan to take them apart so I can make the joystick shafts longer. Here's why. The bottom of most joysticks poke through holes in little metal plates. These are called restrictors. (Diamond shaped holes are used for a 4-way joystick). As a result, the movement of the joystick is restricted in the desired 4 directions (usually up, down, right, & left). This makes switch activation a lot more accurate. I plan to remove the joysticks default restrictor so I can use a special restrictor I designed, which will be located at a lower position, therefore I need longer joysticks. Thanks.

I suspect it is that one end of the original rod is threaded. So what is keeping you from using the lathe and cutting a thread on a longer rod? Dan |

It's a joystick. And I can't find what I need in the size I need. So I figure I'll try to extend what I already have.

The ball-tops don't screw on. They are molded onto the rods.

The idea was to drill a 1-1/4" hole through the center of a 4 inch square piece of 2 by 4. And then cut it down the center into two pieces.
This would be the work holder for the joystick. In the end there can be no protusions, and I'll need to round off the end. Darren Harris Staten Island, New York. |

I'll look into that.

This is new to me. I'll have to research it. It would seem to be the easiest way to get this done.

Have you looked through the different handles and shafts at McMaster? https://www.mcmaster.com/control-handles On the top left side of the link page you'll see a picture of a ball-top shafted handle (Handle Style - Machine). Click on that and scroll down the page. Maybe your could just buy the 3/8 inch ball top handle in 4 inch length and cut it to suit. Providing of course the bottom part of it can be made to fit :) -- Leon Fisk Grand Rapids MI |
