Table Saw from a Circular Saw Redone

http://www.instructables.com/id/My-Table-Saw-from-a-Circular-Saw-Redone/
I bought a good circular saw and hung it below a piece of 3/4 inch plywood. I added a couple of my own innovations, and it could do very precise work. I could also remove the circular saw to rip a panel too large for my table saw, and put it back into my table saw without the need to align it again. I no longer have that circular saw or the table I made. See how I made that table saw here.
But, I wanted to have a table saw again and wanted to utilize my Porter-Cable circular saw (Model # PC15TCSMK). This saw has a rigid base that does not flex easily, a 13 amp motor, and almost no run out to change the line of cut when the motor starts.
What I do not have is a lot of space to store a table saw, so I wanted a saw that almost stores flat. See the second photo. When I want to use the saw, I back my car out of our garage and set up my saw near the open door on folding sawhorses.
Materials

• 3/4 inch plywood 29 x 48 inches for the saw table
• 3/4 inch plywood for the fence and the face of the miter gauge
• Steel bar 1/4 x 2 inches and 1/4 x 3/4 x 24
• 1/4 inch and 5/16 inch threaded rod
• 8-32 machine screws about 1 1/2 inches in length
• Various nuts and washers
• 3/4 inch water pipe
• Angle iron from an old bed frame
• Steel fence post
• Steel electrical boxes and covers for a switch and an outlet
• Three 3/8 inch romex connectors
• 15 amp duplex outlet and 15 amp toggle switch
• Twist on wire nut
• Three prong male plug
• 16-3 rubber covered wire
• Round steel bar to make the collar in step 2
• Concrete reinforcement bar for the carrying handle
• 1/4 inch plywood

Tools

• Circular saw
• Radial arm saw
• Dado blade (adjustable)
• Framing square
• Folding rule
• Router
• Handheld Drill
• Drill press
• Welder
• Angle head grinder with a cutting wheel and a grinding wheel
• 3 pound hammer
• "C" clamps
• Plywood straightedge guides
• Pliers
• Screwdrivers
• Files

Step 1: First step: cut the miter gauge slots

The miter gauge slots need to fit the miter gauge's steel bar precisely. I used an adjustable dado blade with carbide tips to dial in the exact width of the 1/4 x 3/4 inch steel bar I planned to use for the miter gauge. I made test cuts in some scrap lumber. In the process I learned two bars may be classed as 1/4 x 3/4 inch, but one is a bit narrower than the other. I cut my slots to fit the piece of steel I would use.
I also have a radial arm saw now. One capability of a radial arm saw is using the edge of the table nearest the operator as a cutting guide together with a straightedge clamped to the bottom of the work piece. I described that process in this Instructable. I have a piece of 3/4 inch chipboard about 4 inches wide and 36 inches long. It has very straight parallel edges on both sides. I clamped it under the piece of plywood you see in the photo. It was positioned midway between the two slots in the table and was parallel to them. All I had to do was set the depth of the dadoes and hold the plywood firmly on the table while cutting one slot and then turning the plywood end for end to cut the second slot. The process is almost failure proof and the finished product is very accurate.

Easy Aquaponics from "mostly" re-purposed materials

Okay folks - let me have it. My first Instructable was some time ago and it wasn't much so I thought to myself, "how can I really bring some value to the community" and this is what I came up with. My son (15) and I built this over two weekends. Granted, if you had the supplies ready and handy, you could easily do it in a day if you really hunkered down.
Without further delay, I present to you our (roughly) 200 gallon aquaponics system, built from re-purposed wood, a cheap pond kit, some PVC, and lava rocks.

Step 1: Tearing down the old raised beds and getting the base built




 

What really prompted this project was the fact I was getting very tired of the fire ants getting into my raised beds. After losing much of my crops to ants, I decided I was going to grow in water via hydroponics. Then, I learned about Aquaponics and it was on.
Thanks to the help of my son, all of the 6" screws were taken out of these timbers, we cut them to size and ultimately built a smaller version for the tank and used some of the pieces for legs and supports on the grow bed. It is worth noting that we were able to reuse most of the screws that came out of the timbers as well so I did not have to buy any.
The size of my grow bed and the size of my tank were based on mathematical calculations made by me based on the amount of pond liner I had available to me. I bought the kit (see picture) on Craigslist for $25 - it was still brand new in the box. The liner was 8x10 so I had to figure on how much I could use of this. I elected to build a tank that was 2x7 x18" deep and row bed was 1x7 x1' deep for optimal root space. Of course, if you are using a different size liner, just keep in mind that your depth will take off length and width from ALL sides (if you go 1' deep, you need to take off 2' from length and width, which works out to 1' all the way around)

Reclaimed Wood Flat-Pack Picnic Table With Planter/Ice Trough

http://www.instructables.com/id/Reclaimed-Wood-Flat-Pack-Picnic-Table-With-Planter/









Here's our Reclaimed Wood Flat Pack Picnic Table With Planter (I know. It's a mouthful). There is a gutter running down the center below the tabletop surface that can be filled with ice to put your beers in on a hot day, or for planting herbs (reach across the table to get the freshest seasoning for your food) or decorative plants.

Making this table flat-pack was an easy decision: neither of us has a truck.  The table was made in pieces: two ends that provide the structure for the table, two center pieces with the tabletop slats, the trough, and the removable legs that simply screw in place.   Disassembly and reassembly take minutes, and everything can be fit in the back of a compact car.

All the wood in this project is reclaimed except for the table legs, which were purchased from Discount Builder's Supply in San Francisco.  As always, the design was influenced by the materials: we would have made the slats go lengthwise, but most of the beautiful pieces of reclaimed redwood we had were short, so they're widthwise instead.

At the time we made this table, we didn't have access to a jointer or planer, so we sanded our reclaimed wood with palm sanders.  The whole project took us about a week, but it would take far less time with a jointer and planer.

This was made at TechShop San Francisco, TechShop Menlo Park, and in the backyard.  It was inspired in part by Far Out Flora's Succulent Table and Ana White's Outdoor Dining Table.

Note: this Instructable is for the table only.  Another Instructable, for the two matching benches, is coming soon!

Step 1: Materials and Cutlist

The tabletop is 60 inches by 41 inches.  Our trough is 5 inches wide.

Reclaimed Wood:

Tabletop: Wood of varying widths, enough to cover a tabletop that is 60"x41", accounting for small gaps between each slat.  These pieces will all be cut in half, and end up being 1"x any width x 17".

     There are also two tabletop end-pieces that are longer.  These are listed below, under "Outer Aprons".

Table Structure:
     2 Inner Aprons:
          (4) 1x4x64 1/2"  (long apron pieces)
          (4) 1x4x10"        (short inner endpieces of the apron)
          (4) 2x4x10"        (table leg supports)

     2 Outer Aprons
          (2) 1x4x25"         (outer end pieces of the apron)
          (2) 1x any width x41" (Long tabletop slats)

[Note: 1x and 2x mean wood that is "one inch" thick and "two inches" thick.  However, that is their nominal size.  A 1x board is usually around 3/4" thick when measured.  1x boards all used to be one inch, but in order to make them flat, a sawmill had to remove some of the thickness.  Generally, when naming the size of a board, the thickness comes first, then the width, then the length, as in 1"x3"x11".  The x-es stand for "by", so you would say, "One by three by eleven".]

Salvaged length of gutter or trough: 6 feet.  You can also use any old bendy sheet metal if you have it.

Table legs and leg attachment hardware: Throughout our project, we looked for some beautiful old table legs, but weren't able to find any.  We bought ours from a hardware store.  They were screw-in legs with metal top plates that attached to the table top.  They were easy to install, but not as sturdy as we'd like.  If we were to go it again, we would come up with an alternative way to attach the legs to keep them removable, but still sturdy.

Hardware:
Screws: a box of 1 1/4" and a box of 2".  Make sure your screws are outdoor friendly: I used decking screws.

I used a nail gun with 1 1/2" nails and wood glue to attach the top slats to the tabletop supports.  If you don't have that, I recommend using screws and a screw gun.

(8) 3/8" bolts, with one nut and two washers for each.

Waffenherstellung mit 3D-Drucker

Das South by Southwest Festival in Austin, Texas hat seinen Themenbereich in den letzten Jahren erweitert. Ursprünglich nur auf Musik und Film ausgelegt, bietet das SXSW in diesem Jahr über einhundert Veranstaltungen zum Thema DIY. Dazu gehört auch der Themenbereich 3D-Druck. Ungewöhnlich ist, dass Cody Wilson für einen Vortrag zum Thema 'Gun Printing' eingeladen wurde. Wilson ist der Gründer der Gruppe Defense Distributed, die Informationen über die Nutzung von 3D-Druckern für die Waffenherstellung sammeln und verbreiten will.
Defense Distributed ist eine Nonprofit-Organisation, deren Ziel es ist, die Herstellung von Feuerwaffen mit 3D-Druckern für alle zugänglich zu machen. Eine Sammlung von entsprechenden 3D-Designs, die Dokumentation von Tests und die Suche nach der günstigsten Form des Drucks sind die Inhalte, die die Aktivisten verbreiten möchten. Zweck der Organisation soll es sein, herauszufinden „wie sich Regierungen verhalten, wenn sie davon ausgehen müssen, dass alle Bürger fast unmittelbaren Zugang zu einer Waffe […] haben“.
Seinen Vortrag auf dem SXSW hat Cody Wilson dafür genutzt, vorzuführen, welche Designs für Waffen schon vorhanden sind und zu kritisieren, dass sein Anliegen von anderen 3D-Druck-Anbietern nicht gutgeheißen wird. Die Annahme des Jura-Studenten ist, dass die Verwendung von 3D-Druckern für die Waffenherstellung unvermeidbar ist. Da, so Defense Distributed in seinem Blog, die Maker sich mit dem Thema nicht auseinandersetzten, würde seine Organisation dies tun. Das Magazin Wired hat ihn Ende des letzten Jahres auf Platz 14 seiner Liste der 15 gefährlichsten Menschen der Welt gesetzt. Die bisher rund 100 verfügbaren Waffen-Designs wurden seit Dezember 2012 circa 400.000 Mal herunter geladen. Defense Distributed hat sich um eine staatliche Lizenz für die Waffenherstellung beworben.

The FP-45 Liberator was a pistol manufactured by the United States military during World War II for use by resistance forces in occupied territories. The Liberator was never issued to American or Allied troops and there is no documented instance of the weapon being used for their intended purpose. Many FP-45 pistols were never distributed and were destroyed by Allied forces after the war; and most of those distributed were lost or disposed of without any combat use.^[1]

Project History

FP-45 Liberator on display in Les Invalides

The concept was suggested by a Polish military attache in March 1942. The project was assigned to the US Army Joint Psychological Warfare Committee and was designed for the United States Army two months later by the Inland Manufacturing Division of the General Motors Corporation in Dayton, Ohio. Production was undertaken by General Motors Guide Lamp Division to avoid conflicting priorities with Inland Division production of the M1 carbine.^[1] The army designated the weapon the Flare Projector Caliber .45 hence the designation FP-45. This was done to disguise the fact that a pistol was being mass produced. The proposed intent was to drop these weapons at concentration camps where internees would pick up these weapons overcome Nazi Guards and hopefully liberate the camp. The original engineering drawings label the barrel as "tube", the trigger as "yoke", the firing pin as "control rod", and the trigger guard as "spanner". The Guide Lamp Division plant in Anderson, Indiana assembled a million^[2] of these weapons. The Liberator project took about 6 months from conception to end of production with about 11 weeks of actual manufacturing time, done by 300 workers.

Design

The FP-45 was a crude, single-shot pistol designed to be cheaply and quickly mass produced. The Liberator had just 23 largely stamped and turned steel parts that were cheap and easy to manufacture. It fired a .45 caliber pistol cartridge from an unrifled barrel. Due to the unrifled barrel, it was intended for very close ambush (1-4 yds). Its maximum effective range was only about 25 feet (less than 8 m). At longer range, the bullet would begin to tumble and stray off course. Because of the low quality, it was nicknamed the "Woolworth gun."

Wartime use

The Liberator was shipped in a cardboard box with 10 rounds of .45 ACP ammunition, a wooden dowel to remove the empty cartridge case, and an instruction sheet in comic strip form^[3] showing how to load and fire the weapon. Extra rounds of ammunition could be stored in the pistol grip. The Liberator was a crude and clumsy weapon, never intended for front line service. It was originally intended as an insurgency weapon to be mass dropped behind enemy lines to resistance fighters in occupied territory. A resistance fighter was to recover the weapon, sneak up on an Axis occupier, kill or incapacitate him, and retrieve his weapons.
The weapon was valued as much for its psychological warfare effect as its actual field performance. It was believed that if vast quantities of these weapons could be delivered into Axis-occupied territory, it would have a devastating effect on the morale of occupying troops. The plan was to drop the weapon in such great quantities that occupying forces could never capture or recover all the weapons. It was hoped that the thought of thousands of these unrecovered weapons potentially in the hands of the citizens of occupied countries would have a deleterious effect on enemy morale.^[4]
General Eisenhower's staff never saw the practicality in mass dropping the Liberator over occupied Europe, and authorized distribution of fewer than 25,000 of the half million FP-45 pistols shipped to Great Britain for the French resistance. Generals Joseph Stillwell and Douglas MacArthur were similarly unenthusiastic about the other half of the pistols scheduled for shipment to the Pacific. The Army then turned 450,000 Liberators over to the OSS. Resistance fighters in both theatres were supplied with more effective weapons whenever possible, and French use of the FP-45 remains undocumented; although OSS distributed a few to Greek resistance forces in 1944. 100,000 FP-45 pistols were shipped to China in 1943, but the number actually distributed remains unknown. A few were distributed to Philippine troops under the Commonwealth Army and Constabulary and resistance fighters.^[1]

Firearms collectors

The original delivered cost for the FP-45 was $2.40/unit^[3] ($32 in 2010). A Liberator in good condition today can fetch approximately $1200, with the original box bringing an additional $500, with an original extremely rare paper instruction sheet the value could exceed $2000 to a collector of rare World War II militaria. Fakes of these sheets exist, but authentic copies have a watermark that can be seen clearly, which is difficult to duplicate.

The Concept Revived
The Liberator was replaced with the Deer gun in 1964 when a modernized equivalent was designed for possible use in Vietnam.^[3] This was because the CIA needed a weapon of this type, and most Liberators were scrapped after World War II. The Deer Gun was chambered for 9x19mm Parabellum and was loaded by unscrewing the barrel and inserting a round to fire.
