To make the support bar you would firstly decide upon a length to cut the bar. I covered the bar in engineers blue which is a stain and would help show up the marks that I was about to put on then after the engineering blue had dried I measured up 300mm of the bar and marked it up with a scriber and Then I clamped the length of bar into a bench vice to hold it still as I cut it with a hacksaw down to the correct length and filed off the burr using a standard file then using some more engineers blue if necessary then I set up a scribing block to mark the centre of the tube I marked the centre by placing the tube on top of 2 V blocks at either end which prevents the tubes from any movement that would otherwise occur therefore keeping it still all these would be placed on a surface table then you have a scribing block which can be set up to the right height then you move the scribing block across the tube putting on a little bit of pressure and when the line is done you need to get a ruler and measure along the line on the tube and mark out every 30mm using a scriber in line with the line that was made …show more content…
The tube would be fixed to a machine vice in order to be drilled
