when i had one, it was already fitted with the tip and stuff, so not really sure exactly what set up it had, sadly didnt have it very long before life got in the way.
should be able to talk to a local welding supply house and they would be able to give you information on what you need exactly and to get what they recommend for filler rod. buy extra filler rod though. if you think its going to take 6 sticks, buy 8 or 10 lol. if memory serves me right, you should get half the length of stick in weld length. so if the stick is 12", should get you 6" weld. been awhile though but i think thats what i remember.

but thats if your good. ill buy like 14 sticks to cover the pipe and practice. ill definitely talk to a shop.
 
Damn Z! I go on holiday for less than 2 weeks and come back to more insanity! :ROFLMAO::ROFLMAO:?

Have you ever tried tig welding? It is not for the faint of heart. You need to know how to compensate for a ton of variables and have an extremely steady hand. I'm totally all for seeing you burn up some metal, so don't let me dissuade you! (y) (y)

so that's were you've been! Lol. No I have never touched a welder before, that's why I'll buy alot of spare metal and rod, so I can practice before I screw a actual piece up. I Know that people always say Tig is hard and such, but that won't stop me You know! And I really want to learn.
 
What? You though you had scared me off or something? Not a chance! I was in Iceland and Scotland without any cell coverage, and mostly drunk, so I wasn't able to keep up on the forums.

I'm all for you trying and learning something new. If you aren't going to be welding Ti or Al, you can always try Mig welding to start with. It's easier to learn at first, and will give you almost as clean a bead with some practice.

I learned on an Arc/Stick welder when I was close to your age. Family of iron workers made it a required skill. Moved on to using a Mig for sculpture work at University. I have tremor, so I can't hold a Tig torch and rod steady enough to get a good clean bead on small welds like the size of exhaust you're looking to build, but I got damn good with the Mig!

If you really want to learn, I would suggest taking up a welding class locally. Most community colleges offer one that anyone can attend. They cost some bucks, but this is a life skill that you could possibly use in a career (wink to mom and dad). Those classes are actually a hell of a lot of fun. You get to cut metal with fire, and then use electricity to put it back together!

Mig is also a option for me. I'm not sure what I'll do, I do like the challenge of tig, but it seems very hard and time consuming to learn. Depends really on price for me, if Tig is cheaper, then Tig, if mig is cheaper than mig. I'll have to learn either way to get a good weld. Not sure if I'll be able to take a class, by then (this is probably Gunna happen in winter or spring), but if I can that would be great.

its kind of funny about the order you learned, in highschool i started with Arc, went to oxy welding. then about 6-7 years later went to a tech school to motorsport and chassis fabrication and design, i didnt recall too much at the time about how to weld, but they only had so many welders of each MIG and TIG, so i started on Tig, it definitely took a bit of practice, but got it down and loved it. then midway through the semester i had to switch to MIG, got it figured out, but once i got all my lessons and grades done, i switched to TIG every chance i got. almost regret that because i didnt get a whole lot of practice with MIG down, so i can get by on MIG, but it doesn't look pretty most of the time.

Yeah, I'm kind of the opposite. With a gas shielded solid wire Mig, my beads are damn near perfect. Spent a lot of time getting it right though. I hate stick and cored Mig just because of all the damn slag, but I can still get a good bead. Never used a full sized Oxy torch to weld, but I did a lot of brazing with a micro oxy and natural gas torch when I was making jewelry. And of course, having the shakes made Tig an absolute nightmare for me. Good thing I never dreamed of being a surgeon!

I cant find anywhere that would rent a tank

@Z.hb71 that's a bad run of luck there bro! Those tanks are stupid expensive to buy outright. Then you have the regulator and everything else. I got lucky and had an Airgas store nearby. I could rent a tank for like $20 a month, but if I recall correctly, they still wanted a $100 deposit on pickup.

Yeah, I'll keep searching tho. Oxy-acetylene I can rent the 2 tanks but I can't get argon as far as I know so far.
Also how big of a tank would you think I'd need ?

So I'm just gonna toss this out there. Even a cheaper air cooled tig is gonna be in the $250.00 ish range till your set up with everything. Till your done with material purchase and everything you'll be well over your $300-400 price for a pipe. Now add the cost of a class and your prolly closer to the $1k mark. Not saying don't go for it but just realize you'll have more money into it. Now on to cylinder mapping.

Lots of good info from this guy.
Crankcase compression ratio calculator
http://www.torqsoft.net/crankcase-compression-ratio.html
don't get too hung up on it. Remember when I was talking about messing with your crankcase volume? That has to do with the compression ratio. Basically how much pressure and vaccum your piston generates when going up and down. Like I said don't get too over excited about it. Increasing it isnt necessarily a good thing. Search for 2 stroke crankcase volume vs compression ratio in Google and read your hearts content. There have been a lot of debates about making more power from increasing the pressure and decreasing the volume (stuffed cranks and pistons) but there is a lot of compelling evidence that leaving everything alone and making nice transitions to the transfers is best.

Not looking to change the volume, just wanted to know what it is. And if I'm Gunna be spending $300-400 (which it looks like that's the case) it's Gunna be a waste of time and might as well just get someone else to do the welding and such. I'd like to learn at some point but for just one pipe it's not worth it. So I'll design the exhuast myself, buy the meterials, then take it somewhere to get welded and such. Much cheaper.
Also guys thanks for all the welding info and such!!
