How To Make A Tape Wrench Tap Handle

INTRODUCTION :

A tap wrench or handle of tap is a tool used to turn taps and make a thread or other small tools, such as hand reamers and screw extractors. In the market, there are two types of tap wrenches are available double-end adjustable wrenches and T-handle type wrenches. Double-end adjustable type wrenches are also known as bar wrenches, and have one threaded handle which is attached to one of the clamps to properly hold the taps. In the double-end adjustable tap wrenches the clamp is opened to insert the tool and then tightened down against the tool to secure it properly. This double-end adjustable type of tap wrench is used with larger taps and where there is room to turn a larger tap wrench.

The T-handle is more compact tap wrench. This type of tap wrench uses a collet to secure the tool or tap properly. In the T-handle wrench the collet design has two pieces as threaded (nosecap) and four collet fingers. The collet fingers thread on the outside of the wrench and the nosecap is screwed onto the wrench. The threaded nosecap is tapered, which causes the fingers to clamp properly onto the tap. This type of tap wrench is useful in confined spaces and where there extra reach is required. The hole which forms the collet fingers may be sloped or may be stepped. The former accommodates a wide range of the taps, but does not hold properly any of them with special security.

I decided to make a tap wrench with a new design for my own use. This type of tap wrench is very easy to make and is properly hold the taps. Also this type of wrench is used for wide range of taps.

Parts Used :

2 Nos. Solid square metal pieces 12mm*12mm (7” length)
2 Nos. ¼” Allenky bolts (1.5” length)

How to make :

This type of tap wrench is very easy to make and complicated parts are not required to make it. Only two parts are required here; first 2 Nos. solid square metal pieces and second allenky bolts. Not any other complicated parts are required here.

So first of all cut the 2 Nos. solid square (12mm*12mm) metal piece of 7” length. After that, make a V-slot on one side of the both metal pieces by using of hand files.

Now, Drill two holes on the both metal pieces. Drill first hole is of 6mm and second is of 5.1mm on both metal pieces. Then after, make a thread of ¼ BSW in 5.1mm hole by using of ¼ BSW tap set. Now screwed two allenky bolts in both the thread hole on opposite side of each other of both metal pieces.

Now the tap wrench is ready to use. It can properly hold the tap or tool. It is used for wide range of capacity of tap sets and it is very easy to make.
