This is the first boat-building post to show up on my site, but it's actually the third kayak I've built. The first two were "one-sheet" plywood stitch and glue kayaks, each 92 inches in length. This boat will be just short of twelve feet. It is made of pine, cut from a wide board to get a nice quarter-sawn grain.

| You've probably seen how that modern circuit boards are all made with
the new (or maybe I'm just old?) surface mount technology, or SMT.
Well, what's a guy supposed to do when he wants to salvage SMT
components from such "modern" boards? The commercially available
hot-air tools are quite expensive, in the hundreds of dollars, some
even thousands. Hmm. I wonder if I could make one...why not? The
following is a not-yet-complete story of one in the making. |

Here we are pouring a sand casting for the Gingery Lathe I am working
on. It is the head stock casting, note the 2x4 box built to extend the
drag portion of the mold. The crucible was quite full, and when
beginning the pour, the metal was a little difficult to aim squarely at
the mold's pouring cup (note the metal splash).
Click the picture and PLEASE NOTE! The person in this picture is CRAZY! (Oh, wait a minute...that's me!) DISCLAIMER: I assume no responsibility for damages caused by the use or misuse of the information on this web page or site!
Another thing I noted was that the metal was just a touch on the warm side, so the casting had some minor sand inclusions. |
