Pillar Drill Introduction_ There are two types of machine drill, the bench drill and the pillar drill. The bench drill is used for drilling holes through materials including a range of woods, plastics and metals. It is normally bolted to a bench so that it cannot be pushed over and that larger pieces of material can be drilled safely. The larger version of the machine drill is called the pillar drill. This has a long column which stands on the floor. This can do exactly the same work as the bench drill but because of its larger size it is capable of being used to drill larger pieces of materials and produce larger holes. Safety_ 1. Always use the guard. 2. Wear goggles when drilling materials. 3. Clamp the materials down or use a machine vice. 4. Never hold materials by hand while drilling. 5. Always allow the ‘chippings’ to clear the drill by drilling a small amount at a time. 6. Follow all teacher instructions carefully. Cost_ 15000rs Bending M

Aim  :-To study different types of hinges.  Requiremeants:-Different types of hinges as shown in figure  (Takkari hinges,plate hinge,T-hinge,parliament hinges. Process  :-Decide on the of hinges and sizes  depending on the sizeof door and window.Fit                 hinges according to opening of the doors.Mark  the holes by drilling with out making hinges.  Precautions     :-Do not drill hole of size bigger than the screw size.Do not over tightly screw .Do not hammer  the screw .Do not keep the screw head open from outside for the security reasons.  Conclusion :-The size of the hole to be drill should be small then the screw is tightly fitted.

Items: Sand, Cement, Wood Dust,etc Materials  :Phavda,Ghamela,Thapi,Brick making machine,etc Process: Take a measurement of  Brick. 4x5,5x6 inch. Make a molter of water, cement and sand. Use wood to make it lighter.  Make the ratio of molter in 1:6 ratio. Sand quantity:0.26 Ghamela for foot.  Cement quantity:1.5kg.         Labour charge=Material charge /25%=4=17.8/4=4.45 rupees.

Aim : Use tin sheet and give perfect measurement to it , then draw on it then cut it. Requirement: Tin sheet Tools :Big scissor, Hammer, Scale, Pencil & Soldering,etc Procedure: First take a tin sheet then draw a diagram by given measurements. Cut tin sheet in the shape of diagram. Then join the sheet. After joining, solder to it wiht solder meterial. Then cut its lower part in a round shape. Uses: To pour kerosene we use this a lot            We can use to pour liquids to a small hole.

  Aim:- To Prepare R.C.C Column. Requirement :-Tools and equipment measuring tape, thapi,                                 khore, gunny bags,etc Materials :-8mm torshan bar, 6 mm bar, sand, gravels, cement, water, etc Procedure  :- 1) Take torshan bar 8 mm and 6 mm bar  make frame and ring   2) Mix cement, gravels, sand,concrete  3)Take molde and fix torshan bar and fill with concrete 4) use G.I wire to roped it a molde.  Costing of materials:- Sr.no MATERIALS QTY RATE AMOUNT 1 SAND 4  TOPLI 15 PER 60 2 GRAVELS 2  TOPLI 12 PER 24 3 CEMENT 2  TOPLI 8 PER 112 4 TORSHAN BAR    8 MM 1.93 kg 48 KG 92.68 5 TORSHAN BAR    6 MM 0.222kg 48 K 92.68 WORKING CHARGE 25% 95.34 TOTAL 476.70

1.   Karvat  :  Used to cut wood. 2.  Hand driller :  Man power machine It uses to drill wood. 3.  State hammer :   Used to adjust wood peaces. 4.  Ambar     :   Uses to pull nails. 5.  Nishana   :   Uses to sharp wood to make slippery. 6.  Millet   :   Used in adjusting patra to wood.                                                          7.  Kikre  :   Used to remove useless wood.                                                               8.

When we are construct, We want to do one important thing is arrangement of Brick. Stretcher bond : In this bond we can seee the width and height. Stretcher bond       : In this bond we can see length and height. English Bond    : In this bond we use stretcher in second step and hider is we take in constructing. Flaming bond  : In this bond we take stretcher bond and after hider bond and      we taken this two bond the construction is very strong. Rat trape bond : In this bond between three bricks the gap is came the rat live in this and playing becouse after called by rat trape bond.

Aim  :-To learn about treading and tapping        Requiremeant's :- Take a bar of range 18mm to 12mm oil,treading die and use of pipevice. Procedure   :- Threading :-Fit rod in to the vice use of die range to threading give back to forth motion to the die use of oil for lubrication. Tapping :- Drill hole of proper size on the job .It is important to calculate size of hole required. As light drill can be made to fit the tap range .It is just over size then the daimeter  of hole ,deep of the cut is smaller with this tap range . oil is used for lubrication and cooling when aware we rotate we use oil. No tightly rotate because of that oil is to use to smoothly rotate. Conclusion :-Taps and die's are cutting tool'sused to creat    

Lathe machine:- 1) Turning  :-    turning means if any object like wood, metal are decrease thickness is called turning. we use tool and make a design in wood and metal. 2) boring :-   we use boring tools and increase the size of hole.  3) knurling :- use knurling tool to make a grip in metal. 4) tapering :- in lathe machine use tap set to tapping a metal and thearding part of lathe machine    : belt drive,  gear box, head stock,   three jaw chuck, , job, tools, , spindle, , chuck, lead screw, , handle,  tail stock, , bed, etc cost       :-1,10,000
