At no point in the beginning of this restoration did I think it was as big as it was. Like, I knew it was "big" because of the engine size, but like with the Sally Saw, it's just so much bigger than at first glance.

Likely cus they hate us? Slightly more likely is that welding aluminum wasn't much of a thought when they made it. There is a glimmer of hope, depending on if you can find out exactly Which hiduminium alloy they used... I found one article thats hidden behind a pay wall, and a PDF from the company that made the alloy. https://dl.asminternational.org/alloy-digest/article-abstract/4/11/Al-34/399/HIDUMINIUM-RR-58Heat-Treatable-Aluminum-Alloy?redirectedFrom=PDF Thats the article And im trying to figure out how to send you a PDF LoL

Why even use this alloy for some parts of this chainsaw?

Not liking what I'm seeing so far. It's a precipitation hardening alloy, and the hard part is the ~ 1% nickel and iron they threw in... Likely a solution anneal, weld while soft, then re heat treat for full strength, but finding filler to match that mix would be tricky. *might* be able to get away with using 1100 but you'd have a "soft" spot after, and that's assuming it didn't ruin too much of the properties in the HAZ...

Hiduminium. Let me know what you find!

Out of personal curiosity, what alloy was it? I am well aware that many alloys are "near imposable" to weld but I like to figure out the "near" part... like is it imposable because it involves heat treatments that are too expensive to deal with, or does it actually have a metallurgy that prohibits welding.... 7075 is a good example. In the "finished" heat treatments of commercially produced parts, a normal weld will crack like 99% of the time in a weird delayed fashion because of one of the alloying elements not playing right in the as welded condition. However if one has the facilities and reason to do it, 7075 can be welded then heat treated and will work fine...

Another fine restoration. It’s a beautiful machine with lots of danger involved in its use so what’s not to like.

How would you start it up back in the days?

You got me at the loose nut, I chuckled audibly and woke up my 9 month pregnant wife, I hope you're happy with what you've done

Thank you!

Hand Tool Rescue

DO IT!!!! Let me know

Loving this, thanks! And as always, EAAEAAEAG!

Nicholas Leskiw

great show. Was thinking the same thing when wire wheeling the chain. WTF! Also, did I see the fractal chair in the background? Been enjoying your morning coffee in the most steampunk chair of all time?

I can't wait for Making toothpick from log with plane part 2.

Peter Špalek

As an Australian I appreciate good Canadian engineering! Why make something thats easy to handle when you are a Lumberjack!

Dalek Supreme

My guess would be that the company was just trying to avoid chainsaw bar patents for some reason and then designed a bow chainsaw around patent shenanigans to get to this thing?

Serious congratulations on the 1 million subscriber milestone. So well deserved.

Goose Gosselin

I was so happy to see the rusty old Canadian spark plug fire - hope it says in the final build! Pro: Finds the missing dough funnel for the big noodle cutter on auction. 😲 Con: it’s a rare part for the larger “B”/“2” size cutters, so they want 50$ for a bit of cast aluminum. 😮‍💨

John willis

Another glorious restoration. Amazing! Thanks for the tip about oiling the oil. I always felt I was doing something wrong. Now my life is complete.

Steve Z

Who cares? 2 videos in 2 weeks of this high a quality? I'll stick with Jeric!

Mike Bird

Man I love you & your channel! Just sat down with dinner and now I'm watching this b4 many others. #BigSubscriberHugeFan

You can't imagine how much it tickles me when I hear you say "shite".
