    First wife was away for the weekend with her GF, so I got two days to myself, working on the roll cage. Reading this post you might not think I've got much to show for it, but this gives you an idea of how much time goes into building a race car, especially if you are an amateur.

    From previous posts, you will gather that the cage has been fitted up, now it's time to weld. I'm using a TIG welder, which is slow and a bit "fussy" in terms of preparation, all surfaces need to be cleaned with acetone, and joints beveled. So I pulled all the tacked in tubing out on Saturday, beveled and cleaned it, and took the opportunity to weigh it. Here's what 31kg of roll cage tubing looks like:



    I think it will end up about 34 kg with the boxed front foot mounts.

    And after a day's TIG welding, it doesn't look much different. I decided to fully weld the main hoop with it's diagonal brace and harness mounts outside of the car, so I could weld it on the table, whereas the pros tack them into position inside the car. result was the unsupported leg of the main hoop (in the left of the photo below) pulled inwards from the heat of the welds around the harness bar, and is now sitting 15mm inboard of where I had planned. Hopefully I can heat opposite the weld and pull it back to it's intended position, if not, it's going to need lots of muscle power to correct.

    Thanks for your kind words Highco.

    Given the wife was away this past weekend, I don't have a lot to show for my efforts.

    I found some nice die punched bracing plates from an Ebay supplier at a good price, so ordered a pair to tie the front legs into the A pillar. For all you UK and Continental members, I've seen a UK guy who also supplies these.




    I was not too happy with my first attempt at welding the thin plate to the thick tubing, so I carefully ground it off, turned it around and rewelded it using the so-called "lay wire" technique, which is a bit frowned on by professional welders, but good enough for this situation.




    I did manage to clean up and paint most of the tubing with the satin black rattle cans, which did take a few hours of sanding and cleaning prep, none of which is very photogenic. Here's a pic of the plate welded on and painted.




    And here it is sitting back in the car. The paint on both the plate and the inside of the A pillar will need to be ground off prior to welding
