The Romford-based gearboxes have now reached a point where they're nearly ready for release - I hope it'll only be a week or two for the gears to arrive, the first production batch of etches being here already. We still haven't reached the bottom of the stack of etches that arrived last week!
So, there's three in the range. From left to right 30:1, 40:1 and 54:1, all come with two motor mounting plates so you have a choice of 10mm, 12mm or 15mm motor fixings. Useful for Mashima 14xx, 16xx and 18xx series as well as the Canon 1833:
The 30:1 and 40:1 use the same fret and are pretty small for gearboxes of this ratio, so perhaps best suited to older or smaller prototypes, here's a Canon 1833/30:1 from a test etch, the production versions are slightly smaller:
The 40:1 is substantially smaller than other equivalent-ratio gearboxes, which may have a significant advantage in some cases, here it is with a Mashima 1824. Incidentally, by choosing the other pattern of mounting plate the motor can be turned through 90 degrees:
And for those locos where extreme slow-running is required, or if you need to use a small (higher-revving) motor, there's a 54:1 version, shown here paired in a slightly incredulous fashion with a Mashima 1424:
Any of the above gearboxes are £18.25 as a kit (inc. fret, bearings, gears) or £40 as an ex-works unit (customer to supply motor and axle).
As usual there's some literature available from the
Downloads page of the website. For quick links here's the
planning template (pdf, 527KB) and the
instructions (pdf, 680KB).
Markits gears productionisation will continue tomorrow!
