video....splining axles with a totally homebrew machine

That is creative but I'd like to be there when he slides them in. My have to use a little creativity then as well.
Kudos for his ingenuity though.
 
The US used to be that creative, now it's become lazy and cheap.

I was at a salvage yard the other day, 3 trucks there loading up body panels of various vehicles, even roof sections, to be shipped to Central America and Cuba who knows where else.

They'll take them back and the do what "WE" used to do and beat the panels back into shape and reuse them.

Nobody wants to do the work or get dirty anymore, it's just not cool.
 
Wonder how he is indexing it...and how those bolt heads are cutting it for that matter? They may be creative, but our shit usually fits together. :flipoff2:

my guess is he hammered it into a side gear to mark where the splines need to be and then he is using the vise to keep it perpendicular to the cutter while feeding it in. metric bolts are like grade 1 million plenty hard enough to cut that shaft. duh :lol:
 
Knowing the tolerances that it takes for splines to work properly, I doubt that will work or work well. The video says he's repairing the splines which is much different than cutting them from scratch.

Yes, this country has gotten lazy, but given the cost of a machine shop to even open the doors every day, things have to be done in a much more efficient process than this to be profitable. If you think about it, anything metal could be made with simple drills or files, but the time it would take you would be ridiculous! Besides, China hardly even uses manual machines anymore. If it's not an automated machining, you're wasting your time.
 
Im all about homebrew fixes. the old timers made AMAZING things with little to no technology. they are my heros.

From what Ive seen its not that the body guys dont want to fix the panels its that its cheeper to replace them then it is to pay the labor to fix them
 
I wouldn't say we've gotten lazy, just smart. I've seen a tailshaft shortened/resplined with a cutoff whel that worked just fine, but for the time invested it would have made more sense to swap the proper length properly machined shaft in. Like wise with body panels, I could fix the drivers door of my truck, but for the time and materials it would take it's more logical to put a replacment panel on. Chicken salad can be made from chicken shit, but when chicken is readily available why waste the effort?

It looks like the bolts may be being used as a setscrew/counterweight opposite of a cutter. In one frame I think I actually see the cutter sticking out the side of the shaft. I think??.

judging by your name and your comment, im guessing you are/were a machinist. you may be smarter than the average, but most machine shop guys i have met, especially old timers, dont have a clue how to do anything we would regard as "cool", i.e. splining, hobbing internal gears, etc. my point with the video was that most machine shops here know how to drill holes, cut tapers and do very basic stuff by hand. just like everything else in this country, people are too lazy and too cheap to learn to do anything themselves. sure its cheaper and faster to get a shop to spline something for you, but if you can do it on your own its often worth learning. besides, i doubt that guy even had a machine shop available to him that could do the work
 
Thats an interesting way to do that. And yes there has been a major lazy streak. It's easier to buy it to fix it or to buy it than build it. Old timers have some really cool ways of doing things and most are from trying stuff.
 
That is basically the same principle as a horizontal milling machine. Had he been using a carrier or something to index it, and the cutting tool profile was correct, it would actually work fairly well. If you look closely, there are two bolts on the shaft, and a threading tool for a lathe. One bolt sets the depth of the tool, and the other holds the tool in.
 
I'll just do it this way ;)

an old machinist that can cut splines, gears and broach a little as well.
 
semi-thread hijack. I got bored and made this just to prove that chicken$hit can sometimes = chicken salad if you try hard enough. my old willys dash was just rotten to crap so I stole the column surround and made the rest out of 4 pieces of sheet that was laying around. 4 hours invested and $115 saved. recycling baby, recycling. and yes its oil based, brush painted, but who cares it a working truck.

I am a machinist currently. I've been in the trade for 16 years. I've had a totally different experience with old timers. Most of the guys I've know have some pretty good knowledge of how to operate & setup old complex machines. Now we simply use software to program much more versatile machines to do the same things at 10X the speed. There's nothing I love more than old physical tools that used complex gearing & leverage to get the job done! The people that developed those kinds of tools are few & far between.
 
And another thing to be said about this is think about the tolerances that are used these days. Back in the day they could get by with 0.01 maybe more but now a days I've seen drawings with specs down to 0.0005
