Metalworking at the barn

George CarlsonBuild Log, Making, News, Tools

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.  

Welding and Fabrication shop almost ready

George CarlsonBuild Log, News

The welding and fabrication area is almost ready.  The area is located in the South-East corner of the barn.  It is about 14×20 feet, not real big, but should do well for our purposes. We covered the outside walls with steel panels, which assures there is no exposed wood in the shop.  A six-foot high fence with a gate was built to control access to the area.  An exhaust fan will be installed on the far wall to provide good air exchange.  The area has it’s own electrical sub-panel, so installing power for welding machines should be easy. A bit more relocating the material on the west wall, and we should be able to start setting up equipment.  We a very nice oxy-acetylene rig and also some equipment that members are willing to loan to get us going.    

Powder Coating at The MakerBarn

George CarlsonBuild Log, Making, News, Tools

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

Downdraft Table for Sanding and Powder Coating

George CarlsonNews

A new Downdraft Sanding Table was built in The MakerBarn.  The table has a large squirrel-cage blower from a 5 ton whole-house air conditioning/heating unit.  The blower pulls air down through the table top, filters the air with a two-stage filter, and blows it back into the room.   The unit moves a lot of air, and can be used for cleaning the air in the finishing room while using the stationary sanders.  The hood allows the unit to also serve as a powder-coating spray booth. The unit is 60″ wide, 30″ deep, and 65″ high.  It was built using pre-finished birch plywood.  This is the same type of material used by cabinet makers for internal shelves on kitchen cabinets.  It has a tough epoxy finish that is easy to keep clean. The table top is a grid made from the same plywood.  There were over 400 dado cuts made … Read More

Bridgeport Milling Machine for the Shop

George CarlsonNews

 This machine will help open new possibilities for makers at The MakerBarn. The machine is in excellent condition.  It has a 48″ table with movements of 36 x 12 inches.  The Sony digital readout has a resolution of 0.0002 inches for very high precision.  Installing the machine was easy, except it did need quite a bit of cleaning.  It is now up and running so come visit and see what can be done.  Instruction on the machine will be on a one on one basis making a small project to help familiarize the maker with basic metalworking methods.  

The Wide Belt Sander is Ready

George CarlsonNews, Tools

Today Greg and I extended the dust collection system and connected it to the belt sander and the router table. The sander is awesome. We currently have 80 grit belts for fast stock removal, and several other grits up to 220 for finish sanding. The machine is somewhat complex to operate, but still not hard to learn. If you want to get qualified, let me know. We will be changing the V-belts and adding automatic controls for the air supply, but the machine can be run right now.

New Sander for the Woodworking Shop

George CarlsonNews, Tools

Big belt sander  – We are always trying to improve The MakerBarn, adding new tools and materials.  Recently we had a very generous donation of a Sheng Shing SDM-15 wide belt sander.  This machine uses a 5HP motor to power the 16×48″ sanding belt.  The belt oscillates back and forth, which helps lengthen belt life and avoid streaking the wood being sanded.  It can sand a 15″ wide swath, but being open ended on one side, the operator can rotate his panel and sand a piece 30″ wide!  The machine weighs about 800 pounds and is very solid. When we received the machine is was complete, no missing parts.  It even came with two copies of the manual.  The machine was built in October 1996, so we just missed its 20th birthday.  The sander was also in good condition except that all the internal pneumatic tubes had disintegrated.  Not a single … Read More

New machine at The MakerBarn

George CarlsonNews, Tools

The Sieg Super X3 is now at The MakerBarn.  It has a longitudinal travel of 17″, crossfeed of 5.75″ and the head can be moved 15″.  All three of these movements are displayed on the DRO.  The quill has a travel of 2.75″ and has its own digital readout.  We should be able to do some very precise work on this machine. What’s your first project going to be? Soon I’ll post a shopping list for those expendable tools each member may want to buy.  The shop will provide clamp-kits, vises, chucks, collets, and other larger items.  

The Stand is Completed

George CarlsonNews, Tools

The stand is finished, well, until we decide to make some improvements.  The stand has small iron casters to make it easy to move, but also has leveling screws to level and lock the machine in place. Now we await the arrival of the digital readout (DRO) system.  This consists of a display units and three glass scales.  The linear glass scales are packaged in aluminum spars that protect the scale and keep it free from dust and dirt..  The readout device has a resolution of 0.005mm, which is about 0.0002″!
