Awesome
I love the fast forward
I challenge someone, on the next resto project, to video document the whole thing
I'm trying to figure out the logistics of how to to a time laps of the assembly of a bed from start to finish. I would need another camera because my iphone would not have enough battery or memory and I would need to use it ... as... a... phone.
also my software has only preset fast forward speeds of 2x,4x,8x and 20x. Even at 20x I would have to be able to do it in less than 200 minutes to stay under the youtube limit of 10 minute of video. I suppose I could do a part I,II,III,IV,V...
Maybe I'll start at IV like Star Wars
Unless I can assemble one in less than 3hours 20min...

Can I still enter the challenge, if I have only rebuilt the rear axle so far?
Kevin: on your attempts to do time lapse: the GoPro does that. It takes video, time lapse, and stills. Those are the three options, but the time lapse is one of them.

Totally enjoying the vids
Thnk you !
Look so easy to do lol!
Wheels hump, they are coming......
Keep posting those video it's cool to see how you make those parts.

So just out of curiosity, and this may be a stupid question, but Kevin do you think this is basically the same process Toyota had to go through to make these beds back in the day? Do you suppose they had automated fabrication back then, or was it done by hand using tools like that press? Pretty fascinating to watch this process, especially if it resembles the original fabrication process.

My opinion only, but this first video is what I imagine the stamping of parts like floor pans, bib, bezel, doors... pretty much everything was made back in the day.
The only difference between that and modern stamping is the size of the tools (dies) and the complexity of the parts (meaning the number of bends, ribs and ripples). The actual presses used are the same with regard to basic design. It's the control systems that have gone from mechanically adjustable stroke limits to CNC.
If you watch closely you will see the dies are progressive - meaning the first press will stamp the basic shape, the second might trim off excess material, a third may add a couple more bends etc. This is true for all the three videos. Only the control systems change over time. The basic function is the same. Positive and negative shapes are milled out of solid steel. A thin piece of sheet metal is placed in the die and you squeeze the piss out of it. Doesn't really matter whether a man uses his hands to move the part or a robot does.

What I do with all my fancy bending is use creative flat layouts, bends and most important, welding in certain spots to mimic the one step stamping shown above. The early cruisers and on into the 45lv definitely were made by hand to some extent but there was always some stamped parts in the assembly. Over time the hand work would have been phased out and more, and more accurately stamped parts would have been used. The stamped panels would have been put together using several jigs where a few parts would be clamped in place and then spot welded and even hand welded in places. Slowly building up the tubs until they were done.
They will be welded to the side panels. More accurately they will be brazed to the side panels using the TIG torch and silicone bronze filler rod.
Uploading another vid now....
Is that the same as mig soldering, using CuSi-3?
Do you have experience with that, in mig or tig?
I'm looking at an inverter with CuSi-3 option on it and was wondering if that would be a better option too build up the panels. A lot less heat.
It doesn't work on every mig, you must be able to turn it down to 15 amps.
There are mig welders with special settings for it.
Do you have experience with tig soldering?

No, just the Everdure product. But it doesn't actually melt the parent material when you use it so it is kinda like soldering. It's tricky to use because its a fine line between having a ball of molten filler and then it spreads way out with just a bit more heat. I tend to put too much on and then grind it off, which is Ok because I am using it for cosmetics rather than structure. Almost as a "metal bondo" or like lead filler bodywork in the old days. It is softer than the steel and grinds away easy.
Are these solid or filled bars?
Thank you, I can work with that.
Think I will try the TIG first before I buy a new mig.
