A carbide holesaw would have cut the whole 5 times faster. And little filing after. Welders and fitters like to use harder/ old style techniques. Make it more complicated

great stuff!! thats one the best ways to find the center , but an ol timer taught me that you gotta divide your O.D by half after leveling your pipe and using your big square (depending on pipe) and level mark it and there you have a true center 👍🏻
I have never seen that center punch mark trick to keep from losing the marks! That is definitely going on the mental to box. Great info, great video. Thanks 👍
I learned the center square method in a fab shop I worked at. As a matter of fact, I learned how to do all kind of shit with the center square. Good stuff!!
Wow I really enjoyed this. Learnt heaps. Great teacher right here and very humble at that. This video will definitely be copy and pasted into my welding tips diary 📔.. thanks mate. Legend 👍
As an old welder fitter you done good. Easier to cut the inside line and grow the hole, you will not get any more flow with an oversized hole and may create a vortex with flow and bypass. Good tips for the newb tho.
Great knowledge! Only problem is, if you were my high school math teacher I probably wouldn't be welding 😁 just kidding! I eat sleep weld ! Thanks for the great tips!
Nice video :-). But with calculator in hand I would not round anything while doing the math. Rounding can come back to bite you so IMHO it is a habit to avoid unless you are forced to do the math long hand with a pencil ;-).
I agree, doing the math not rounded was roughly 1/16” different or about 1 degree. After you factor in the thickness of the marker I was using, etc... it really doesn’t throw it off enough to affect the overall outcome of the layout. Thanks for watching sir!
I did my apprenticeship training at sait in Alberta. Another good way to find your center mark for your fitting from top dead center is using this formula. Degrees divided by 360 - take that number and times it by the radius, times two, times pie. That’ll give you the full arc length. Looks something like X*/360* x 2 x r x 3.1416 Both work just as well, just something different!
I always take a welding rod, at about 2" use channel locks to bend a hook. Then when i start my hole with the torch, put the rod in. Keeps your coupon from falling in the pipe. And no soapstone at WeldTube?!?!
im a commercial pipefitter...woulda used a mechanical T....i'm also a welder....still woulda used a mechanical T....(installs with a drill and hole saw, for those of you that dont know.)....what you welded on has no connection point....no victaulic or threaded connection....what connects it to your next section of pipe?.....or do you weld all of your pipe?.....
It’s a socketolet, one side saddles the pipe and the other side is a socket connection. I have never fit for anyone else only myself, I weld all my own joints, a one man show if you will. Thanks for watching and your input! Take care sir!

Cool video and educational. I’m a machinist by trade 33 yrs come October. The biggest thing is see with the younger generation coming into our field or Maintance in general is they can’t read a tape measure, a rule or a scale. They won’t ask for help or when they do they loose interest or don’t pay attention. Just my little rant. I’ll be using the tricks with the center head and framing square. Even an early 50’s old guy learned something today. 👊👊👊
Yes, only error in the video is he said PI is 3.14 inches which isn't quite correct. PI is unitless. You can convert directly into the arc length from degrees by using the formula PI X Deg X OD / 360. Put whatever units you want into OD and it will give you the corresponding arc length of the same units. If you use the same numbers from the video in the formula I've provided it will give you 1.34" of arc length at 28 degrees with the 5" pipe (5.5" OD). This is exact. In the video he rounds pretty significantly which would cause him to be off by over a degree (29.1 vs. 28).
I just stumbled into this channel and it was very interesting. I followed all your calculations up to where .05 was 1/ 16th of an inch. I know this video is two years old but if somebody runs across this and can explain it to me I would be very grateful, thank you
1/16 of an inch is also measured as 0.063 (63 thousandths of an inch). He realized that .05 was basically a 16th and that was close enough for the math he was doing.
Faction measurements can be converted to decimal take top number divided by the bottom will give the decimal . 1/16 is .0625 I worked I CNC machine shop and used a similar formula to machine .
Excellent info. But one thing that you can build on all that math work, has to do with A) estimation of pi and B) round off error from division. Instead of getting intermediate numbers from every step and getting approximations, do all the math in one fell swoop, and you will be even more accurate. IOW, do: 5.5 x pi ÷ 360 x 28 all in one-step on the calculator. You end up getting 1.343903524, which you can *then* round off to 1.34" which can then be translated into 1/32s to try and maintain the accuracy (it ends up being 1+11/32 ". You end up getting less cumulative round-off/estimation error, and you end up with a more precise location which is roughly 0.050" from where the 1.4" measurements lands you, which coincidentally ends up being roughly 1° off. Just food for thought from someone who has a good formal training in math. ;)

Slide a file over the center punch marks to shine them up a bit and make it a little easier to see while cutting

Very cool, could use a klein inclinometer as well on top of your framing square. Zero at TDC and slide the square around the pipe to whichever degree
That's the way I do it but this stuff is good to know.

True welder/fitter👍🏽 don’t really see that anymore
Good one but one question. What's the purpose of the welding rods taped to the pipe? Allow full bead on the inside?
I use tig wire to space the weldolet off the pipe 3/32”
As an old welder fitter you done good. Easier to cut the inside line and grow the hole, you will not get any more flow with an oversized hole and may create a vortex with flow and bypass. Good tips for the newb tho.
Glad to see someone useing the down and dirty ways that still work to do this
Also that square edge is more important then most would every understand
Great knowledge! Only problem is, if you were my high school math teacher I probably wouldn't be welding 😁 just kidding! I eat sleep weld ! Thanks for the great tips!
I use a 6010 rod on the core side to torch melt into the cutout piece, so it don't drop in the pipe
One of the best tricks there is when your adding on to a existing system that is drained.
Nice video :-). But with calculator in hand I would not round anything while doing the math. Rounding can come back to bite you so IMHO it is a habit to avoid unless you are forced to do the math long hand with a pencil ;-).

proportion
28o / 360o = x" / 17.27"
so x"= 28o * 17.27" / 360o = 1.34"
They should have taught us these practical applications in school and make the subjects interesting. What a waste of school life. Thank you man
I did my apprenticeship training at sait in Alberta. Another good way to find your center mark for your fitting from top dead center is using this formula.
Degrees divided by 360 - take that number and times it by the radius, times two, times pie.
That’ll give you the full arc length.
Looks something like
X*/360* x 2 x r x 3.1416
Both work just as well, just something different!
Did anyone else notice he was using the stinger end of a carbon arc?
I use an optimus 400 amp stinger
that trick with the framing square to find tdc is amazing. cant wait to try that
"I'm a welder, not a fitter" , try telling my boss that.
😆😆
Great video and sound quality. Hope so u do welding with good quality also. :D
Pie is a contestant not in inches. Say you can lay out your paper flat and measure it right on you paper to.
Why don't these guys wear respirators?

I need one of those center punch deals u got there ....
Thank you! I have one question, how do you weld that fitting for it not to move up and down or side to side?
Roll the pipe to 12 Oclock Level. Tack it, then Roll it back down to the Degree needed to make the fit.
4 tacks about an inch long, feathered.
Great video Thanks for sharing
Thanx for the video learned something.
