I am typing on a fully assembled new prototype F62!

We are getting there – thanks to everyone for their patience with the factory delays.

The feel is very comfortable to type on. Another buckling spring fan in my family hit 112 WPM on 10fastfingers with this first-run F62! You can really notice the difference with new springs that have not been worn out and oxidized after 30 years, some more than others – creating an uneven typing experience with a high-mileage Model F.

Everything is working very well so far. The powdercoated die cast zinc cases are excellent quality. It was well worth the couple extra months to get the paint job right. The off-white/beige color is almost an exact match to the 1988 F107 case I mailed them as the reference.

The texture is the same bumpy, mostly matte but slightly reflective powdercoating as the original. The True Red and Black cases look good. In the next week or two they will mail the Industrial cases.

The capacitive PCBs, controller PCBs, inner foam, and outside foam are all good. Every PCB is being grounded in two spots to the bottom inner assembly with 6-32 screws to eliminate the risk of stray capacitive signals.

There were a number of issues that I have told the factory to work on and prioritize for completion as soon as possible. Some notes:

The top inner assembly parts are very good but slightly off spec. The TIA curve is about 1mm off from the ideal. My XT sample has a perfect curve that matches my CAD files exactly so I have asked the factory to remake the samples to this standard. The perfect curve helps ensure a more even pressure on the barrels between the top and bottom inner assembly. The wrong curve can result in wiggly barrels and clicks that are not as sharp so it is important that they get it right. To correct this issue they are going to adjust their tooling and mail corrected parts ASAP.

The compact cases had some issues with the color of the hard anodizing being slightly off. They are adding another couple screws on the bottom to further secure the case.

The product boxes were 2.5mm thickness instead of the 5.0mm I had specified so those were rejected, though the box artwork is well-printed.

Finally the springs are very close to the originals but I want to see a few more spring samples with different materials before the springs go into production.
The springs have improved sound but the top inner assembly needs to be re-made and accurately curved before the Model F sound is at its sharpest. Currently it’s well within the range of the original Model F’s that have gone through my refurbishings over the years.
