George Carlson was interviewed at last year’s Houston Maker Faire by Spaceboy. It’s a nice overview of the history and philosophy of The MakerBarn. Video courtesy of SpaceboyUniverse on Youtube.

Sand Casting at The MakerBarn

Clay McGovernMaking, Materials, News, Tools

The MakerBarn recently added the capability to cast non-ferrous metals. One of the simpler ways to cast metal is to use sand to make the mold. At the Barn we have Petrobond, a special sand mix for casting. This training video shows the making of a branding iron with “The MakerBarn” on it. First a pattern was cut from Corian using the CNC router. This pattern was used to make the sand mold. Scrap aluminum is then melted and poured into the mold.

Metalworking at the barn

Woodworking has always been a big part of the work going on at The MakerBarn, but now we are seeing more metal projects being built.  With the completion of the machine shop, addition of powder coating, and the near completion of the welding shop, expect to see even more heavy iron at The MakerBarn in the near future. Jody Cochran is powder coating a small weldment used on the new miter saw table being built by Kyle Fraczek. It’s just a large washer with a 1/2″ nut welded in, but you could never find one at the hardware store.  It’s used for mounting the feet on the large cabinet. Rob Nixon made this super dial indicator holder for the lathe.  Made from 6061 aluminum, brass, and steel, it should last a lifetime. This is a special quick-clamp designed for the new welding table.  It is a good example of offset … Read More

CNC Router Class

George CarlsonEvents, News, Tools

The CNC Router Class held on March 26 was a success.  The class covered CNC (computer numerical control) in general, and specifically for the CNC Router.  In the last half or the class, V-Carve was discussed and examples were done.  V-Carve is the CAD/CAM software used for controlling the CNC router.  It is a very powerful design program that can be used to generate DXF files for the laser cutters as well as G-Code to drive the CNC routers.  The MakerBarn is fortunate to have a makerspace license for V-Carve which allows members to use V-Carve free of charge on their own computer. The next class will be held on April 23rd.  There are only 8 openings, so be sure to sign up early.  Contact George at geotekds@swbell.net for questions or reservations.  This is a members only class, there is no fee for this class.
