Model M Rivet Replacement - Sandy's Mod American Style This article is an Island. It cannot be linked to using wiki BB-codes.



First you need a bunch of tiny itty bitty little parts.





FOR A 1391401 (may vary a bit for other M models)

58 2mm x 8 x .4 Pan Head bolts - can order at McMaster Carr

58 2mm x .4 Hex Nuts - can order at McMaster Carr

8 2.5 mm washers

1/16" or 51 drill bit and drill (dremel best)

4mm socket

Chisel



OPTIONAL

2mm x .4 or 2-56 tap

Electric screwdriver

Female hands



I found this stuff at my local True Value store (told ya we're going metric) but you can also order online. Doesn't need to be fancy stainless steel or anything - buying German though feels right. If you have a choice get the lowest profile head bolt. Buy a few extras of the tiny parts, you'll see why in a bit.



First remove the grounding screw and gently rock the membrane connector to remove.





Chisel away the rivets with a twisting motion - you want a CLEAN cut. Sharpen your chisel first if it's not razor sharp.





Pull off the plate (if it doesn't come off easily check for rivets under the labels). Then the sheets, the rubber mat and turn the board upside down into a box or something to store the springs.



Time to drill. If you cut cleanly with the chisel this will be easy - if you didn't prepare for pain. The goal is to drive straight down into the stud. I used the slowest speed on my dremel.





Art Break.





Clean this stuff off every so often.

Sandy's mod to replace the IBM Model M plastic rivets with nuts and bolts is a classic. I got curious though what would happen with a Model M that was NIB - would I feel and hear a difference? Other geekhackers have reported feeling a difference so I tried it with a few little twists of my own.First you need a bunch of tiny itty bitty little parts.58 2mm x 8 x .4 Pan Head bolts - can order at McMaster Carr LINK 58 2mm x .4 Hex Nuts - can order at McMaster Carr LINK 8 2.5 mm washers1/16" or 51 drill bit and drill (dremel best)4mm socketChisel2mm x .4 or 2-56 tapElectric screwdriverFemale handsI found this stuff at my local True Value store (told ya we're going metric) but you can also order online.
