A video for the machinists on the board

This video shows 1) amazing machine work and 2) some of the best commentary I've heard in a long time. It is long, but if you are in to creativity and machine work, worth the watch. Caution: Canadian curse words aplenty!!

 

Awesome machine shop stuff: a couple notes: 4130 (chromo) yes man, was someone complaining about an axle? No lubricant: he said it work hardened on him. Thus why we use lubricant, he was lucky it was not Inconel 718 talk about work hardening. The broach, it's like that, but I have never seen a screwdriver tip used as a broach. Good to remember Ding. I normally go to Western Broach for my dumb ID relief's. Taping: back the tap off more than he does, breaks the chips. Running the die: some imperfect threads, turn the die over and pray. Helicoil blind hole: You need to make that Helicoil tap a bottoming tap by removing one lead at a time (4 times). Then keep it if you need a bottoming tap again since now it is worthless except bottoming. Bottoming helical drill (same thing). The reason why Helicoils are crap: The lead in is blunt, it just sucks, everyone loves a countersink that slowly leads into the thread. He called it a Pin, it is a shoulder screw. Using Moly-sulfide on aluminium pivots, not a good plan. He said he had some garlock bushings, then you do not need moly. Moly is hard, rock hard and it will grind the Al Aly on every motion.
But an excellent adventure in fixing a design flaw created at manufacture.
PS: Beer in BC is sold warm, if you are camping like me you need to buy ice with every 6 pack eh.

 

He is certainly colorful. But he’s been repairing tractors or something if a fine pitch bolt is considered exotic in his part of the world.

And designing that part in anything but aluminum would be silly. The steel repair part in 4130 is fine, but red loctite on the coarse insert means the next shock service will scrap the bike.

MIL-TFD-41C.

 

Machinists.........ahhhh, I thought it said masochist.

I'll see myself out.

 

Well duh!

You certainly wouldn't want to use anything but an aluminum fine-pitch bolt made of MIL-TFD-41C on your hobnostal defosticator! Does it work with resin pads?

 

So that's how Machinists talk?!

 

I'm not gonna watch a machinist video during after hours beer drinking time. Maybe tomorrow morning...

 

I’ll know now that dropping the F bomb during conversations is the norm when I am out riding with those who are Machinists.
