Custom made in Sheffield for Workshop Heaven, these extra long Y-lever castings are designed as the ultimate bench plane upgrade for those who like to indulge in a little bit of hand plane fettling.
As the name suggests, you file the rough casting to fit your particular plane, precisely!
Much of the ‘feel’ of a bench plane comes from the fit between the Y-lever, the adjustment wheel and the cap iron. Fine tuning these relationships to closer tolerances can transform a standard Record or Stanley bench plane into one that truly feels hand built.
You are aiming for a ‘close running fit’ between the contact surfaces of the adjustment wheel, pin, cap iron and Y-lever. The sum of the tolerances in those areas will determine the amount of hysteresis (often incorrectly referred to as ‘backlash’) in the mechanism as a whole.
As well as the additional shaping on the tab, we have also added some extra meat to the ends of the arms, so that the fit with the adjustment wheel can be fine tuned. The position and diameter of the hole is also crucial to keeping just the right amount of slop in the mechanism: present, but minimised.
We took the foundry owner's advice on the best available grade of gunmetal to use for the castings, quite a bit more expensive, but it is absolutely gorgeous material to work with hand files and laps. Brass would have been cheaper, and fine for a component that won't have further work done to it, but it clogs up your metalworking files a treat, rendering them all but useless - you wouldn't have thanked me for that.
Gunmetal is a traditional planemaking material common in infill planes, possibly for the reasons outlined above, it is also self lubricating, corrosion resistant, and when finished and polished looks the business!
