Part 119: Channel Segment
|119||Channel Segment||1923||1935||8||0||n/a||n/a||'Large Wheel Segment' until 1924|
Clive Weston has found even earlier UK price lists, August 1923 for the introduction and March 1924 for the new names – we're awaiting scans!
Eight were included in the outfit 7 of 1925 (enough to make one wheel), increasing to 16 in 1930 (when 8 were also included in the outfit 6). These quantities continued in the K and L outfits of 1934, but were dropped in 1935 when the part became one of the very first significant obsolete parts in the Meccano system. The 1935 printings of the F-L manual include several models where the picture clearly shows channel segments, but the text explains that these should be replaced by the new Ring Frame (later Large Flanged Ring, part 167b). This would seem to be a cost-cutting exercise, and would have created some disappointing models as the large flanged ring is considerably smaller.

Although DMS/EMP describe only channel segments with holes on the flat face, the earliest versions had no holes on this side at all. If you look very carefully at the Meccano Magazine extract above, you will see that the Channel Segments are attached to the hub disc by 2½''x½'' double angle strips. This is the only method possible with the first version of the part, shown as part 119.ni in the table below.
The "Improved Meccano Parts" announcement is in the January 1929 issue of Meccano Magazine, but it seems most likely that this change was significantly earlier, probably mid-1928. Further examples of channel segments will probably help us date this change better.
Variations and oddities
In that article he describes how the first couple of thousand made were unstamped, but the subsequent ones are clearly stamped W.R.I., as the example shown above. You might also just notice that the left-hand side hole is not perfectly circular because of the process used (which he mentions on his site), and this key identifier helps you to spot an unstamped WRI part. However, all the two-lug nickel Meccano parts found to date are stamped Meccano.
These excellent replicas were only A$35 for a set of eight (which is a fraction of the price an original Meccano set would fetch). These parts are no longer available new as, sadly, Bill passed away in May 2009. Further information is here.
Ashok also makes reproduction channel segments, of a modified type where the two lugs oppose each other on the two curved sides. This allows the ring to be stronger than the one-lug "type 1" variant, but still allows a smooth flat surface for use as a built-up roller bearing. Although this is a clever variation, it doesn't represent a Meccano part that was ever made.
Dealer spare parts boxes
Now that would be nice. The parts themselves are rare enough, and I've never heard of a spare parts packet, but surely they will exist somewhere. Has anyone ever seen any?
Individual part numbersPart numbers for the parts on this page are as follows: Unique part numbers
For identification, each variation has been given a suffix to the main Meccano part number. These suffixes consist of a two-character code for the colour, and if there are many variations, a further number and sometimes letter code to identify each variation. See the bottom of the 'Parts' page for further details.
You don't need to worry what the codes are, just click on any one for a photograph.
The button above turns on and off the display of DMS numbers (where they are known). The DMS (Development of the Meccano System, Hauton and Hindemarsh) published in 1972 and added to in 75 and 82, suggested part numbers for every variation of every Meccano part. These numbers aren't perfect, but they are recognised and also referenced in the EMP (Encyclopedia of Meccano Parts, Don Blakeborough).

|Medium red, two lugs, three holes on flat section||33||.mr1|
The Channel Segments are painted red before they gain the extra holes and lugs, however we can safely assume that these later types were available as a special order part in nickel plate, along with most other parts. The entries above are therefore theoretical, but likely to exist.
Please send us pictures of missing parts! Hints and tips for pictures
Take a picture of the part in very good light, preferably on a plain yellow background, without a flash but with a tripod.
Ideally, trim the picture to about 150 pixels per inch of the Meccano part (unless the part is particularly big or small), save it as a reasonably good quality jpg file with a filename of exactly the part number, for example 19b.ni1.jpg, and email it to us by clicking on 'Contact us' at the top of the page. Thanks!
- A greyed-out box shows that no part exists for that colour combination.
- Part number codes with a green background have an attached picture of the part, just click once on the code to show a photograph of that part in a separate window.
- Parts marked "" were temporary or economy parts, or existed only within specific themed outfits. The previous part continued throughout or afterwards.
