make a Wilesco dome whistle fit on a Jensen75 can it be possible i've got the whistle stuffed in a drawer-doing nothing-I'd like to put the tooter to some use.

I would think not easily. Wilesco is metric and jensen from memory is 7/32 imperial

you could find a bolt that is the smae size as a jensen whistle and drill a hoel through it and tap it to fit wilesco and presto. I have done it with my Indx model 200 since I had a spare wilesco whistle | ||

Nothing is impossible

Well, I made a little adapter for him so he could make the wilesco whistle fit on a jensen. Will put up pic tomorrow. | ||

Clever work their Ranger. Did you drill then tap the metric Wilesco threads??
Were you able to find a bolt that simply threaded into the Jensen whistle hole?? Just curious how you did it? Roger |

I'll get some pictures of what I used to make it. The process is realy simple if you have the right tools. Until then I used a brass hose connector, (forgot what its called) and my dads tap and dies set. Then I cut a the long piece off the hose connector and the hole was just the right size to tape for a wilesco whistle. To make it fit on the jensen I found a bolt that fit in the boiler and matched a die that fits and with alot of fuss trying to get it strait about 30 minutes later it was done. Took about an hour to do the whole process. | ||

Ranger, I think all the threads are different for each style of whistle
|

Hey Hey Hey, Dont go ruining all this good fun. That whistle was a dome whistle at one time, only thing is everytime I made it whistle it burnt my fingers because the steam went 360 degrees around the whistle. The threads should be the same on most of the whistles. Since he ahs a dome whistle it should be ok, I hope |

Sorry mate! | ||

Very clear Ranger...same principle would apply to any engine, whistle combo if you have access to the taps and dies.
Good work! Rog |
||
| Cranko |
Have you retaped the whistle hole in the top of the boiler
|
||
| rangerssteamtoys |
No, I tapped the adapter to fit the jensen on bottom and wilesco on top | ||

| steamyman |

please chk your pm.

Jeez, well done Ranger, great vid. I like that kind of engineering, way to go man!
If you ever figure out how to make your own steam valves or whistles, I'd like to hear about it! 
|
||
| steamyman |
so would I.
|
||
| rangerssteamtoys |
Steam valves......Hmmmmmm well I have tryed in th past but its worth another try
|
||
| oldstuff |
Me too...pretty frustrating...I never solved it. 
|
||
| James |
You mean a regulator? | ||
| mc_mc |
How do you use those taps and dies? Just clamp the piece in a vice and then forcefully screw it on some how?
It's not something that I've ever seen done. |

Basically, that's it, but you have to be a bit more carefull than that. The main precaution is that, for every turn clockwise, you should back up half a turn. Otherwise, the thread clogs up with swarf in a couple of turns. If your tapping steel then it should be lubricated. You should also make sure the tool is perfectly upright at the start - you can't correct it once it's started!. The only other thing to watch is that the hole or rod is the correct size to start with. Honest - it's much simpler than it sounds once you've seen somebody else do it and you've had a go yourself. |
