Yamaha 360 is a good bike. I had a (mostly) stock one. It had excellent balance., great feel. I think a homemade chamber like this should be as short as possible, but, go with the math! ,,,Izzy Strong,,,,
your tig wire must be rusty due to being old or kept in a damp place that's why it looks like your welding with a sparkler. use mig wire its cheaper! Also thinner so it doesn't take as much heat to join the weld pool so you will have a thinner and less blobby weld. try to use a bench grinder or even a cutting disk when sharpening your tungsten so you don't have abrasive/bonding contamination. everyones a critic I know, Im no expert myself but it makes a hell of a lot of difference. you will find you will have to feed more so u will get the weld pool rings more consistent. AND most importantly only wear a glove on the hand you hold the torch with! its soooo much easier to feel what you are doing with the wire and when auto feeding the wire between your fingers n thumb becomes 2nd nature start wearing the glove again. well done anyway. ive gave you a like. keep up the good work
Top tip - grind all the pie-cut ends flat and fuse weld them together. There shouldn't be any need for wire... well maybe a little if it blows through.
Around 3:30 you stack the pie cuts and it had to be approx 12.250. How did you know you were at that length you just went a ahead and started welding. Not coming off rude I love the vid good info I’m actually trying to make one myself using the same spreadsheet!
The best way to find out would either be to measure across the center of the tubes using a string line, or measure each segment before welding. I could have been off a bit, but I wasn't too worried about it haha
I could easily clean them up a bit, but it's my first real TIG project and I'm gonna keep it as is. In a couple years when I have some skill developed, it'll be cool to see where I started!
@@FormulaJake up to you of course though you can see exactly where you started by watching this video you posted to the world. It be interesting to see how strong this sort of quick and dirty welds are compared to something done proper and back purged.
Definitely. I know back purging is much more crucial for stainless, and isn't as big of a deal on mild steel. If it were stainless, it would be a disaster on the inside.
Just checking my understanding , needs to be 12 inches of curved lengthy before the expansion chamber , would you just measure with a piece of string I’m guessing
Remember that the curved tubing is measured at the centerline of the tubing. You can use a string, but since I made pie cuts and measured the height of one piece, and stacked enough of them to get 12 inches
@@FormulaJake i mean.. The stroke is the same my main concern is pin diameter. Not a bad job on that exhaust. I'm getting ready to do a street tracker build with my 76 dt400. So I'll be doing a low pipe.
Johhhh. People like smoothe welding on a oioe. Betyer use oxy acethileen welding. Nobody like bumpy welds. Just giving u my opinion and from people around me
Any of them will work! In our part 1 video, we showed our spreadsheet in a Google Sheets document. Here it is! docs.google.com/spreadsheets/d/1nksxtd8M9KeJJ8l10ZHtq8yk8W6gZQZhXmFXj4fGZC4
Well done mate, I like your honesty! Tig welding is hard when you start out but fun!
You could also use a jet washer to hydraulically form the expansion chamber 🔧👍
Great Stuff - your are very talented Guy!
Good job man ,i am learning from your video,thanks deeply
Hey thanks for making this video! This is great information and was just what I was looking for!
Glad it helped! We have a couple other parts as well, and part 4 (silencer fab) is in the works!

great job! thanks for all that information as well :D

Thanks for the good criticism! I need all the help I can get, lol. Great tips 👍🏼

What type of welding do you use to weld the exhaust material?
I used TIG welding
Get yourself one of those harbor freight band file Sanders and clean those welds right up

@@FormulaJakemy bad Thought it was stainless...
@@axa.axa. You're fine! I'm new to this, eventually I'll try my hand at stainless but not quite yet.
This kid is smart he just doesn’t know it yet.

A wise older man said to me once . Nothing "s easy !
That's a dt400 yes?? With an old-school aftermarket head.
Not sure about the head, but it's a DT360. I have a 400cc cylinder sitting in a box, ready to be installed some day 👀
@@FormulaJake i mean..

Bro , that was a calculation chamber EXPANSION,, 🤔🤔🤔 a ? ?, it's a 175dt Yamaha, headblock can be fitted on RX 135 .
dt250?
DT360 🤘🏼
You could of sanded those welds bro of you wanted it to look pretty.
I definitely could have, and I guess I still can! But it's a nice reminder of where I started welding. And it fits the ratty nature of the bike 👌🏼
next time use a much larger cup like a 13 k bro
Biggest I have is a 12, I'll give it a shot 🤘🏼
Johhhh. People like smoothe welding on a oioe. Betyer use oxy acethileen welding. Nobody like bumpy welds. Just giving u my opinion and from people around me
It can be welded smoothly with TIG, it just takes practice. This was my first time welding pipes, I'll get better 👍🏼
@@FormulaJake ok that i understand totally. Respect!
@@FormulaJake which software do u use to calculate the pipe? TsR. Wizzard, Bimotion pro??
