It can comprise of two clamping aid tools (100) and (130), each having i.e. a 1 inch elongate slot along its length. This allows equal size straight edges of 1 inch minimum width to be used to extend the length of the tool and hence the accuracy of the angle finder. It can act as two separate torpedo levels (a level with multiple vials for checking various angles, including vertical, horizontal and 45 degree surfaces or other degrees common in different trade work). It can be used with various component brackets disclosed, to perform various other functions. The center of the ‘V’ grooves on the top edge surface of the first component bracket when attached to the clamping aid tool of the angle finder can align with the center of the top edge surface ‘V’ of the other clamping aid tool of the angle finder.

[0124] The present invention also provides a hand clamp adapted with clamping aid elements for use with the clamping aid tools of the claimed invention. A jig for clamping can include one or more clamping aid tools for use and mounting with various common tools, including a carpenter square, framing square, speed square, and various straight edges, for easily and accurately positioning various objects, either flat and/or round, magnetic or not. The clamping aids can easily clamp such a square to round pipes at correct angles while being fitted, secured and/or welded together that may be difficult or impossible to do. The square can be clamped for most or all of the process to increase accuracy and efficiency of the work, prevent errors and save money. The claimed invention as a whole, is a versatile tool or jig, that can be used in many different arrangements and replace several tools such as a corner clamp, a variable and/or extendable angle finder, a speed square, a welders magnet, a torpedo level/extended level, a ‘T’ square, a Try square, a depth gauge, a combination square, etc.

[0125] The clamping aid tools can be made of any suitable material or alloy metal that is durable, including aluminum, steel and or hard plastic or a combination of materials. As an example the main body will preferably be aluminum, and any clamping aid tools with a level feature will include spirit vials made of typical construction.

[0126] The triangular square and alternative speed square can be made of traditional materials, such as aluminum or hard plastic, but most likely of a durable aluminum material such as aircraft aluminum would be ideal.

[0127] The component bracket can be of various metal alloy material but again, most likely of very strong aluminum;

[0128] The various hand clamps can be made of various materials or a combination of various materials, depending on the type of hand clamp. Various hand clamps can be adapted with a clamping aid element(s), and the element(s) can include some or all of the features of the clamping aid tools of the present invention. These clamps can include various locking clamps, bar clamps, regular ‘C’ clamps, pipe clamps, etc.

[0129] Magnets included in accordance with the present invention can include earth magnets, ceramic or other suitable material.

[0130] Mounting screws can be made from a metal alloy, including brass which may be non-marring.

[0131] While embodiments of the invention have been described in the detailed description, the scope of the claims should not be limited by the preferred embodiments set forth in the examples, but should be given the broadest interpretation consistent with the description as a whole.
