Next on the list of stuff and things and whatnot.
My TOP SECRET project is nearly there. I spent a solid 18 hours working on finishing stuff up followed by dropping the parts at the powder coater that morning. Yeah, I literally started doing the final work on the project at around 11:30am and didn't stop until after 6am the following morning. I went and showered and then dropped the parts off. Hopefully they'll be done by next week.
I decided I wanted side rails like those available for so many other Toyotas. I found a decent deal on some 200 series Summit side rails from ARB. They match the main bar diameter of the Tundra/Sequoia Deluxe Bull Bar, 60.3mm OD.
I had to print a jig to help align the rails at the bullbar and a jack and some tape to line everything out. I trimmed off the brackets at the bottom using my trusty Milwaukee corded portaband. Then I lined up the bars to figure out where to drill the holes in the main bar for the attachment hardware. You can't use the 200 series rough measurement. After figuring out the rough alignment I taped the main bar with painters tape, realigned my rails and traced the fitting.
I used the paper templates and drilled a hole in conjunction with the tape marking. I drilled just large enough for the allen bolt to go through. I attached the rail and checked fitment. I then removed the rail "tuned" the front facing hole with a round file and re tested. Then I went through and drilled the front hole for the remaining piece.
With the rails loosely hanged, shimmed out from the fender and leveled to the silder with a floor jack, I made my preliminary cut of about 2.5" from the slider end.
Then I went about using a small remnant piece of birch plywood butted against the inner rail of the Tandem slider to make a tracing of the contour. I measured, plotted points and drew that up in Fusion 360. This along with the rail dimensions allowed me to make a cope in Fusion 360 which I printed and mirrored. I was able to utilize that cope jig to get a rough cope on the rails.
I wanted the rails slightly longer and I knew they would require welding to the sliders. So I devised an adapter to lengthen the front and one to act as a joiner at the rear. I printed and test fit the adapter and decided I was okay with it. I didn't like where the joiner had to go but there wasn't really a better place I could think of. Anyway I sent out the files for quotes; and after having 3 pretty crazy quotes for the small parts I decided to just buy a small metal lathe.
I have some other things I will need a lathe for and I've wanted one for years but just couldn't justify it. However, with the price of the 4 parts plus what I will need made in the future, it made sense.
Here I've made the first adapter, it is only 35mm longer. I also turned down the original attachment piece. I didn't want to make the side walls too thin. Looking back I think I would have liked to extend the main tube, not the front bend. It would have kicked it back just a little farther and made it more anesthetically pleasing. I only had a 12" piece to work with, if I had gone any longer I would have had to buy 5 feet. The local metal supplier had this remnant laying around and sold it for a decent price.
Here I have all the parts made. It started as a 12" section of 2.5" OD .500" wall DOM.
I then made jigs to hold the pieces in my drill press vice, as well as, allowing me to drill the pilots, rotate them and put a pin in the backside. This ensured 180⁰ of separation.
