Tangent Corner / Tools Explained.

                                                                                                                              Tools Explained

DRILL PRESS: A tall upright machine useful for suddenly snatching flat metal bar stock out of your hands so that it smacks you in the chest and flings your beer across the room, denting the freshly-painted project which you had carefully set in the corner where nothing could get to it.

WIRE WHEEL: Cleans paint off bolts and then throws them somewhere under the workbench with the speed of light. Also removes fingerprints and hard-earned calluses from fingers in about the time it takes you to say, 'Oh sh--!'

SKILL SAW: A portable cutting tool used to make studs too short.

PLIERS: Used to round off bolt heads. Sometimes used in the creation of blood-blisters.

BELT SANDER: An electric sanding tool commonly used to convert minor touch-up jobs into major refinishing jobs.

HACKSAW: One of a family of cutting tools built on the Ouija board principle... It transforms human energy into a crooked, unpredictable motion, and the more you attempt to influence its course, the more dismal your future becomes.

VISE-GRIPS: Generally used after pliers to completely round off bolt heads. If nothing else is available, they can also be used to transfer intense welding heat to the palm of your hand.

OXYACETYLENE TORCH: Used almost entirely for lighting various flammable objects in your shop on fire. Also handy for igniting the grease inside the wheel hub out of which you want to remove a bearing race.

TABLE SAW: A large stationary power tool commonly used to launch wood projectiles for testing wall integrity.

HYDRAULIC FLOOR JACK: Used for lowering an automobile to the ground after you have installed your new brake shoes, trapping the jack handle firmly under the bumper.

BAND SAW: A large stationary power saw primarily used by most shops to cut good aluminum sheet into smaller pieces that more easily fit into the trash can after you cut on the inside of the line instead of the outside edge.

TWO-TON ENGINE HOIST: A tool for testing the maximum tensile strength of everything you forgot to disconnect.

PHILLIPS SCREWDRIVER: Normally used to stab the vacuum seals under lids or for opening old-style paper-and-tin oil cans and splashing oil on your shirt; but can also be used, as the name implies, to strip out Phillips screw heads.

STRAIGHT SCREWDRIVER: A tool for opening paint cans. Sometimes used to convert common slotted screws into non-removable screws and butchering your palms.

PRY BAR: A tool used to crumple the metal surrounding that clip or bracket you needed to remove in order to replace a 50 cent part.

HOSE CUTTER: A tool used to make hoses too short.

HAMMER: Originally employed as a weapon of war, the hammer nowadays is used as a kind of divining rod to locate the most expensive parts adjacent the object we are trying to hit.

UTILITY KNIFE: Used to open and slice through the contents of cardboard cartons delivered to your front door; works particularly well on contents such as seats, vinyl records, liquids in plastic bottles, collector magazines, refund checks, and rubber or plastic parts. Especially useful for slicing work clothes, but only while in use.

SON-OF-A-GUN TOOL: (A personal favorite!!) Any handy tool that you grab and throw across the garage while yelling 'Son of a GUN!' at the top of your lungs. It is also, most often, the next tool that you will need.

Thought I would post this just in case any newcomers are unfamiliar with the tools we use for our delicate CNC work.

Sorry Guys just couldn't resist - got your attention though.

Happy New Year to you all.

This may be too risque - if it is moderators please delete.



General Mach Discussion / Free 2D Clipart.

For those of you who use Vectric software (or anyone who can translate a .CRV file) the nice Guys there have an advent calendar and are giving away a free 2D clipart image each day up until Christmas. http://www.vectric.com/WebSite/Vectric/seasonal/christmas/advent-calendar-2010/vecric-advent-calendar.htm



These downloads wil, I believe,l work with the trial versions of Vectric software so anyone can use them  ;)

Tangent Corner / The first of the Winter Snow.

Looks like winter is here, the first snow fell last night.  :'(

The "old swimming hole" has been drained down ready for the winter freeze and it's time to get in the stock of survival beer.


Tangent Corner / Scary ??

This brought back my memory's of bungee jumping.  8) 
Watching this video, I found myself holding my breath when the guys got to the antenna part - see what you think (it's better watching full screen).

If this Guy ever builds his own CNC machine I would really love to see the pictures.


*****VIDEOS***** / Laser Raster Engraving.

I have already posted this under the laser project thread but it is perhaps helpful to have video's all in the same place.

This is my video of laser cutting the Mayan calendar into Obechi. It's really quite boring, like watching paint dry, but the music is good  ;D

Something that would be nice is a 'progress bar'.
Large DXF's take some time to process - sometimes it works OK sometimes it locks up - a progress bar would at least let me know something is happening.


In some ways this is a continuation of ‘The Laser Project’ but because there are many ways in which 3D Printing can be achieved I thought it perhaps deserves its own thread. The method I have decided to initially follow is that of Selective Laser Sintering. http://en.wikipedia.org/wiki/File:Selective_laser_melting_system_schematic.jpg

My initial model is only 2D (about 3mm thick) and was produced in just two layers using a simple stacking frame – this has, however, given me sufficient confidence to start building a larger frame or jig with a moving Z Axis base that will allow models up to 60mm deep to be produced on my existing machine without any additional modification. If this is successful, who knows?
My initial inspiration for trying this came from the Candy Fab project and more details of their progress can be found here http://candyfab.org/

Although I accept that the quality of my initial model is not very good I think that by using fusible materials which have a finer grain structures things can only get better.

I would appreciate your comments / suggestions relating to this or 3D printing in general.
