    Scaled up Cracker

    This will be my build log for a scaled up Cracker. I had every intention of making 2 identical Crackers for my son and daughter. Then I saw xo18thfa's Nina build and I decided to make a scaled up version of the Cracker. I am scaling up to 1/16th for every 1mm. I will still make the smaller...

    Small Tap Wrench

    So I have hit a snag with my .60 Crusader build. I have also not been able to visit the shop as much as I would like. I have visited here almost every day if not twice a week. I started on a Rocking engine to take a break from the Crusader and ran into a problem. I have no small tooling! No...

    Titanium in the home shop...

    Had some time to work on my Cusader WIP and decided to machine the last crankcase. Since I had broken my last insert in my boring bar I tried a brazed bar from my boring head. Worked OK but I had to keep depth of cut to .020. Now the problem. I had built up enough swarf to make a rather large...

    Chuck issues

    Guys, I have an old Takang TK-105 lathe circa 1978. It came with a PUUR chuck which I am told is an old Bison and the spindle is an A1-5 mount, not common. Lathe: My lower jaw on one of the jaws was broken before my tenure and the previous owner just ground the rear 3 teeth off! This makes a...

    Honing a tool (how to)

    I have seen many references to honing a tool to get a sharp edge. I bought a diamond lap and I use it pulling away from the edge like sharpening a knife. I have seen a couple of references where it was used pushing towards the edge. Is there a right way? I would think that removing material...

I decided to take the tailstock apart and found 2 6" Tilton steel rules under the joint between the base and the tailstock. With those removed I...
