Although my 200ml upright Reilang oiler seems to be an excellent piece of kit, I find that the flexible spout is a bit oversize and awkward when it comes to filling oil caps on eccentrics and other parts that are under the boiler and between the frames of my 5" Alice class quarry Hunslet. I would like to make a new spout that reaches those places that other spouts can't reach. The thread on the existing spout seems to be 7mm external diameter and has a very fine thread. Can anyone suggest a way of identifying that thread please?

Use a thread gauge or simply measure the distance between thread crests. Once you know the pitch in mm, you can look it up in a thread chart.
Alternatively, someone here will either know or measure it for you.

Yours must be different to mine. I've got half a dozen or so solid spout ones (200, 300, and 500ml) and they all seem to be 8mm x 0.75mm pitch.

Which I am perfectly capable of doing and arrived at 9/32" x 32tpi. However, I am sure you will agree that, for a Swiss product, would seem somewhat improbable! |

i use my reilang oiler for steam oil as the super duper pump on it is great for steam oil.
i have an ordinary oil can with pump for lubricating oil. this had an ali curved pipe on the end which removed and i cut back and tapped 3/16" x 40 tpi or whatever suited the bore then a matching fitting was silver soldered onto some 3/32" dia thinwall long length copper tube to screw into said ali oiler spout and has never failed to 'reach the parts others dont reach'. the same oil can has now been in use for 31 years.
cheers,
julian

Thanks Baggo, I knew it was not M7 x 1, but M7 x 0.75 is a pretty near to 9/32 x 32 tpi and that had been my previous best guess Just curious, is yours a fairly new one? Just wondering if they have changed the thread size. Mine are all s/h ones picked up from Ebay so probably quite old. John |

Just wondering if they have changed the thread size. Mine are all s/h ones picked up from Ebay so probably quite old. Mine was bought new not much more than 3 years ago. The difference between 7mm and 9/32" is less than 3% and the difference between 32 t.p.1 and 0.75mm pitch is about 6%. At those sizes I do not have absolute confidence in my ability to distinguish between them. But Reilang is Swiss so I am betting on the thread being M7 Fine and will put my money where my mouth is and order taps and a die later today. |

I said measure the pitch in mm, not the tpi. That way, if you measured the diameter in mm, you wouldn't arrive at 9/32" x 32tpi.

I have a very old Reilang oiler which must be forty years old at least and it has a fine spout as referred to earlier in a post. they are metric threads but may be swiss metric as used in portescap motors used in OO models? These threads are based on a constant pitch system as is BSP BSB and cycle threads. Morris cars used a French Metric system on their Bullnose cars.

Next thing you'll want the moon on a stick. Sheesh ! Some people are never satisfied. Oh! But I am! And I thank you for your kind suggestion which I would be happy to accept in the spirit in which I am sure it is meant. Should the stick be measured in metric or Imperial units? Also, do you think it wise? The Americans have planted a flag there and they might want it back. |

Unfortunately, wooden sticks are only sold in 300mm units as they don't sell it in feet any more. Consequently, I can't get the exact size to reach the moon and it's so expensive I would rather not buy too much and have to cut some off.
As far as the American flag is concerned, I thought that the consensus of the conspiracy mongers was that it was all a "set up" and the "so called moon landing" was actually on earth - as the flag moved in the wind. |If that's so, there wouldn't be a flag on your moonsicle.
