  • Finished my workbench!

    I finished my workbench. It took me about 12 months and a broken toe to do it. Very happy with the result but now I need to fit the vice. I copied Paul Sellers’ design from his YouTube videos. In fact his videos inspired me to get into woodworking to start with.

  • I am transitioning GPG keys

    -----BEGIN PGP SIGNED MESSAGE-----
    Hash: SHA1
    I am transitioning GPG keys from an old 4096-bit RSA key to a new
    4096-bit RSA key.
    This transition document is signed with both keys to validate the
    transition.
    If you have signed my old key, I would appreciate signatures on my new
    key as well, provided that your signing policy permits that without
    reauthenticating me.
    The old key, which I am transitional away from, is:
    pub   4096R/505E764E 2011-06-28
          Key fingerprint = B10B 2E72 BB30 FE47 ABC2  F1B9 FA57 1EC7 505E 764E
    The new key, to which I am transitioning, is:
    pub   4096R/93176CCD 2016-10-14 [expires: 2026-10-12]
          Key fingerprint = 4639 4DFE EFF0 344F E116  E974 C4E9 00B0 9317 6CCD
    To fetch the full new key from a public key server using GnuPG, run:
    gpg --keyserver keys.gnupg.net --recv-key C4E900B093176CCD
    If you have already validated my old key, you can then validate that
    the new key is signed by my old key:
    gpg --check-sigs C4E900B093176CCD
    If you then want to sign my new key, a simple and safe way to do that
    is by using caff (shipped in Debian as part of the "signing-party"
    package) as follows:
      caff C4E900B093176CCD
    Please contact me via e-mail at <jason@dickson.st> if you have any
    questions about this document or this transition.

  • Command Option R on a Windows keyboard

    Today I had to do an OS X internet recovery but I only had a Windows keyboard. Normally the keyboard combination to launch the Internet Recovery on Macs is Cmd+Option+R but I couldn’t find the right combination on the Windows keyboard. After much googling and experimenting, it turns out its Windows+Alt+R

  • Poor man’s router with wedge fail

    Poor man’s router with wedge fail

    I tried making a Paul Seller’s style Poor Man’s Router plane. It worked quite well but I couldn’t get the chisel’s blade edge to be really perpendicular to the surface of the wood. As an alternative I thought I’d try cutting a slot into the piece of timber and making a wedge to fit it to hold the chisel in place.
     

    As much as I tried I couldn’t get the wedge to hold the chisel firmly enough that it wouldn’t slide up once I started cutting into wood with it. I think this was partly to do with it being a bevel edge chisel. This meant there was less surface area in contact with the wood, so less friction and easier to slip.
    I might try making a hardwood wedge for it. I also need to try a firmer chisel instead of a bevel edge one. The extra surface area might be enough to hold it.
