modified quick 360 angle ruler

RFQ Description

I have modified a Quick 360 Angle ruler to give me a true centre line reading on the angle ruler I need some help with this as I damaged the digital reader when doing the modification. WE are an engineering company in Scotland UK We specialise in cutting metal parts for welding and manufacturing parts for equipment .These parts come in various shapes and sizes and on occasions it is tricky to do an accurate drawing to be converted into a code for the machine that cuts the shapes.WE have found that one easy way is to do a polar point drawing with a selected start point in which we than take an angle measurement and then measure the distance from the selected point to a node on the perimeter of the piece being drawn To be accurate we need to take the angle measurement from the centre of the ruler not one edge. At the moment we use a plastic 360 round protractor and an ordinary ruler to get an angle point and a distance.We purchased a Quick 360 digital angle ruler but we cannot use this to take the measurements since it does not have an open centre to accurately determine the true angleWe dismantled one of your angle rulers and had a centre slot cut on one arm of the ruler See attached photo We would attach the ruler to a drawing board and then take measurements at each the points on the perimeter of the piece to be drawn This is quick and accurate I have attached photos of the alterations I made to the angle rule, I had a slot machined down the centre of one of the arms My reason for doing this were that I wanted to have an instrument that could identify the true centre line angle of the lines to be measured. Without this the lines would be off set from the true fulcrum What I am attempting to do is possibly a bit academic but I would like the measurements to be true angles to the fulcrumThe measuring ruler mechanism became damaged when it was being machined I will now need to replace the angle measuring piece with a new one or have the ruler sent somewhere to be repaired .Could you help by either supplying me with the digital gauge which I could repair the altered ruler or suggest a repair company (preferably UK) which could repair it for us. I could send the ruler to ChinaI do believe that the digital angle ruler would be improved if they came with a machined open slot down the centre of one arm I think other people would be interested in this for doing drawings I shall be pleased to have your thoughts on what I have said.Thanks Robin I have photos but could not add them here
