In this video we learn about the Sony digital readout system on The MakerBarn’s Bridgeport. This video is Part 3 in the MakerBarn Bridgeport video series.
This video describes some of the major accessories available for the Bridgeport Mill at The MakerBarn. This video is Part 2 in the MakerBarn Bridgeport video series.
An Introduction to the Bridgeport milling machine by George Carlson. This video is intended to help introduce the milling machine to new users. It not intended to show operation, that will be covered later. This introduction is the first video in a planned series on the Bridgeport.
Demonstration by George Carlson of using 3D printed models to make metal castings using sand. The parts are upgrades for the TronXY X1 3D Printer.
A demonstration of Investment Casting using a 3D printed model. The printer was a Wanhao D7 using Senertek Castable Resin.
A tutorial on setting up and using the dedicated dado saw at The MakerBarn.
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.
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
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 email@example.com for questions or reservations. This is a members only class, there is no fee for this class.
With the completion of the downdraft table/powder coating booth, and the acquisition of a new oven, we now have the facility to do powder coating. Powder coating is a process where a dry powder-like paint is applied to a metal piece using electrostatic attraction. The piece is then baked in an oven, causing the powder to melt then polymerize into a very durable coating. Here’s an example. This is a butterfly cut from a piece of 1/4″ steel using a plasma cutter. The butterfly was cleaned and then blasted in the abrasive blaster to remove the mill scale and give a nice even surface for the power coating to adhere to. After this point in the process you should use gloves to protect the clean object from oils on your skin. Oils on the surface of the part are not good for the powder coating. The powder is then … Read More
