cutting steel - accuracy

[robo]

If you are having problems with your freehand cutting get one of these gadgets http://www.ebay.co.uk/itm/4-1-2-ANGL...8333%26ps%3D54 The do them for 9" grinders as well. Used with a thin disc it would do all you need. Its not a good idea to gap craft the joints because the weld will pull and cause distortion making it harder to keep everything in check. Practice weld on all the off cuts of material before you start on the chassis, good luck.

Thanks for all the advice.

That tool for the grinder looks good. I will order one of those.

I have redone the sections that I wasn't happy with. Cutting long and grinding to the marked line works well.

I am only tacking at the moment and practising fully welding on offcuts as I go. One of the reasons I wanted to do the whole thing myself was to learn new skills like this so its good to get advice on here and see my work improving.

Thanks guys.

Good on you, its always good to learn new skills. The closer and neater you can make your cuts the easier it will be to weld, also make sure that where you are welding it is clear of rust and any protective coatings, i.e. oil are cleaned from the area, remeber clean is good

I was in a similar boat and wanted to learn some metal working skills while building mine. I ended up using a black perm marker to draw the lines for the cuts, then cut slightly wide on purpose with a cutting disc. I then slowly grinded away all the black ink from the pen using a grinding disc to get my final line and then took a metal file to it if it wasn't a flush fit.

Will take about 20 thin cutting discs to do a full chassis
