Re: IBM 3278 beamspring keyboard restoration and usb convert

Very impressive! Though I must admit I laughed a bit when you used a pen to outline the holes just after showing a cad model of the part when then was laser cut and bended :) I had a hard time to convince a local plastic laser cutting shop to cut me the foam from the cad model but after 5 attempts ...

Re: IBM 3278 beamspring keyboard restoration and usb convert

Very nice restore! I’ve had one like this in the past and what really kill things is if the springs and stems are rusted though, so I’m glad yours was salvageable! How did you restore the case? Chemicals vs sandblasting, or both? What type of paint? I gave the case to a car paint shop and a color s...

I've restored a pretty rusty 3101 but this is another level! amazing work, an inspiration for sure.

Re: How to improve MX Blacks?

Hi,
I like linears and I find that mx blacks are too heavy for my fingers too.

I usually replace them with lubed Gateron yellows as You can see here, where I replaced even the pcb in a g81. If You buy them from china they are extremely cheap.

Re: IBM 3101 Restoration and Cerakote

I remind You that, if you plan to install a controller, all metal parts must be in electrical contact with each other and grounded to the controller, especially the upper and lower plates or Your controller will read wrong and erratic capacitance from the key presses.

Hi,

I've been given some 3276s to restore and some have one or two yellowed keycaps. I know how to retrobright but I'm afraid of bleaching the caps. Did anyone attempt a retrobright on those?

Re: Beamspring Factory process - How to

"The external coil springs are probably the last unsolved element at this time. "

Check Aliexpress, https://www.aliexpress.com/item/3296025 ... 4c4d90iFjC

Those are havier than the originals but better than none.

Re: UPDATED: IBM Model F restoration - May 2019

Great work!

And what a rust! I personally would have sprayed an antirust paint first on the plate as a prep to the final paint , but that's a matter of preference.

Thanks for the cross link to my Model F restoration video!!!
