Today I finished up fitting the pass down tube, made some gussets with smaller diameter DOM tubing, and welded it all in. I had an "aw crap" moment when I realized that my cage fit so tight that I couldn't slide my bars forward enough to lower them to weld the top halves. To solve this I had to remove the support that runs across the roof panel. Glad that was only spot welded at the ends and not along the roof itself. I did make 2 slight positive bumps in my roof moving the cage forward, oh well. I'll see if I can tap them back down at a later point. I also rattle canned the bars to minimize flash rusting. At a later point I'll add a bar that runs across the main hoop for mounting seatbelts after I get seats, mount them and all that. Same for adding angled tubing from that point to the frame rail itself. In the meantime I will add a few attachments to the body to stiffen the body, and a few more gussets, too.
Just a few hours today so i worked on mocking up the driver side down tube. It fits better than shown in the pic, it was difficult to hold it flush and take the pic. I tacked it to the main hoop and will start on the pass side next time.
My neighbor bent the tubes for me and I started to mock up the main hoop inside. It's just loosely sitting in there, it's not squared up yet, but I'm very happy with how it fits and it's going to be nice and tight to the body.
Small update today so I finished up modeling the downtube. I only need to mock up one, and then have two bent to match. All the support braces, gussets, and such don't need to be modeled up. I may still model up a side bar for the doors but I'm thinking about a removable one, so nothing is built yet. I know there are various clips and bolt in mounts, etc. I could use so I need to look into it more.
