I spent abort four hours last night filing, and I've got about two more left, before I have enough stock removed to get a good space for the junction of the bolster and handle. I really need to learn how to fuller, accurately. I've been using a 2# hammer and a framing hammer, and made a makeshift fullering tool that has successfully pissed me off... I've also got to get my forge hotter.
I would love to see the hay rake tine integrals! I've got two head bolts and two rocker arm pins from a large Cummings engine I got from the scrap pile at work. They all seem to be pretty good steel. Im not up to forging the 1 1/4" pins yet, though...
