Can You Shorten My Pipes? Part 1

In this job, Im tasked to modify a pair of heat riser manifold pipes. The customer is making some engine modifications to on old Plymouth motor and he can't find these in the correct size needed. So I decide to cut them apart and put them back together in the length he requested. In this first part I explain my way of doing this job, lay out some steel for a jig plate, and build the jig to hold the parts. Mill work, including drilling and tapping, use of a slitting saw, and welding is what you find in this series.

[@not2fast4u2c]

I enjoyed seeing you do the Old School way of marking out the lines for the holes and making a jig to hold the part Looking forward to seeing part 2

[@stewkingjr]

If you stop the video at 14:20 it makes a pretty dramatic single shot with nice composition and lighting. And i like the way you explain what you're going to do, and then while you're doing the work. You're a pretty natural teacher.

[@Abom79]

Using a Sharpie isnt a method I have ever adapted to using, although I see it a lot more thanks to Keith and Tom. As I started, theres always more than one way to approach a job. Cutting it in the mill was the quickest and easiest method for me.

[@Abom79]

With hot rolled steel you have to deal with the mill scale on the surface. Many people disregard this but its what needs to be known. I know people in industry (think papermills) dont worry about it and paint right over the scale. Thats fine for normal industrial applications. Cold rold steel is more suited for machinists because of it being on size and no scale. Lots of the simple line shafts I build are made from cold rold shafting.

Adam I just like the way you work. your attention to detail and care taken in even the simplest tasks is a true testament to the quality of your work. I have really Enjoyed all your videos, your clear concise way of explaining your process is amazing. you have the gift of teaching and am glad you have found a forum to do it. I wish you all the success in the world and wanted to just say thanks for the entertaining and educational videos.

[@Abom79]

patrick jaroch Thanks for the comments Patrick. When I turn the camera on it just feels natural to explain my thoughts on the job I am approaching.

[@norceck]

The most informative machinists ever. A Pleasure to listen too. Always wanted to do some machine work with the real machines. Always had to do things with hand tools. Now in my 70's Only if I were 30 years younger. Love Your Teachings.

[@Abom79]

+Norman Recek Thanks Norman!

[@Abom79]

Good question Harleyghost. Theres a big difference in hot rold and cold rolled steel. Hot rold steel has a mill scale on it, and its not perfectly on size. the edges are more rounded off, and if you measure it with a mic or caliper you'll see its not perfectly on size. Cold rolled is manufactured to be right on size, within a thou or two. It is also perfectly square on all sides. Its much easier to use in making parts because of it being on size. It also does not have the mill scale.

[@Abom79]

Thanks. Making the jig plate was the way to go. It kept the halves perfectly square and aligned.

[@Abom79]

Bill, we used to have a nice carbide scribe, but I think it was lost with all the chips somehow! We used it all of the time but one day it just came up missing and I never found it again. Ive always wanted to buy another one, but just never have. I did buy the scribe you see me use in the video, not long ago. Its a Starrett! I only bought it because it was in our inventory at work and I had to have it. but I use it often!

[@bufford14]

Young man, it's amazing to watch your mind at work. That is a sure fired way NOT to get it wrong. Love your work, I'm going to episode 2 and see the rest of it.

[@leonardcolvin4398]

Old school,out standing! Keep up the good work.

[@Abom79]

Welcome to my channel orbiter8, and thanks for the sub! I'm glad your enjoying my work, and look for part 2 coming soon.

[@darodesk]

I love his old machines, made for centuries :-)

[@Abom79]

LOVE the Kool Mist. Its works good, keeps everything cool, and blows the chips out of the cut. Great for machines not equipped with flood coolant.

[@SlowEarl1]

nice set up fixture can't wait for part 2.thanks for doing what you do.

[@Abom79]

I used a bottle of the red Dykem layout fluid. I have a small bottle of the brush on, and also a can of the aerosol for laying out large parts.

[@oink079]

Speaking of punches...that might be a good subject to go into further. I would like to see more of your layout methods and how you might redirect a punch mark that didn't exactly hit the target. I've noticed you go all out to do the best job possible. Very respectable.

[@Abom79]

Thanks Scott. I didn't worry about a gusset because I felt the tack welds would hold it good enough for what I was doing. Second video will have slitting saw work.

[@floridawind1]

Part 1was great, we are all ready for part 2 now :-) also, would love to see you do a short video on power taping in the mill. Gill

[@Dsp.Studios]

Cool idea for the job Adam, looking forward to see the part 2 :)

[@Abom79]

Thanks Gill! I bet you enjoyed the "hands on demonstration" I gave you today! You need to get one for the Bridgy. They help a lot! Thanks for checking out the new video!

[@tomharrell1954]

That’s so cool. You made a jig! I would have done it like that too. But I think I would have just made a new part from there! Don’t have to deal with the cutting and welding on old pipe.

[@Abom79]

Surface finish, and being on size. With cold rolled you dont have to mill the factory rolled sides to be on size, so they fit in the mill vise nice and square.

[@Abom79]

Experience is always a help with what I do!

[@paltryengineer]

Outstanding Adam, i had a think about how i would have done this while you were explaining the job and i wouldn't quite have approached this job quite like this, i still would have made a plate but i would have cut them and machined the halves separately to size, i like your idea much better good stuff

[@davewood406]

I was going to ask this very question. All I knew from my uses of both is that the hot rolled was that there was more pre-paint prep work. All I use it (angle and c-channel) for is structural bracing. Pretty rough dimensions compared to machine work.

[@Abom79]

Thanks oink079. I will take that into consideration for future videos involving layout work. I always strive to do the best job possible.

[@Abom79]

Yes sir! I have to admit I made myself look like a fool punching those marks and not having my glasses down. I strive to always use my PPE, but I guess I forgot to slide them down over my eyes for that part.

[@Abom79]

Thanks Mark! Hope you enjoy the second and third videos too!

[@MatthewTinker-au-pont-blanc]

Thanks, it's what I thought!! Thanks for your videos, I'm very much a learner and I find your videos useful. I bought a metric 150mm hook scale on line from the US as here in France, they are not available! Regards, Matthew

[@62346]

elegant plan, nice work Adam!

[@Abom79]

Thanks Gill! Part 2 is on the way soon. I'll be sure to make another "Shop Talk" video on power tapping in the mill!

[@Abom79]

We've never had one but aways wanted one!

[@rchopp]

Looks like a good plan, nice job.

[@StraightThread]

Nice job, Adam!

[@Abom79]

Thanks rchopp!

[@Abom79]

I'm not quite sure which handle your referring to Tom. I think your talking about the quill handle though. If so, the quill handle is the factory style that you have to pull out and reposition. But I'm used to it and react to moving it around pretty quickly.

[@OrbiterElectronics]

New subber here to your channel Adam.. Liking your shop and the work you do a lot my friend. Looking forward to pt2 on this job now :)

[@floridawind1]

I like your cool mist system Abom. Gill

[@1954BJohn]

Great skills Adam

[@laurentcnc6662]

Hi Adam. Great fixture design simple and effective, I guess years of experience were talking ;-)

[@harleyghost]

Enjoy watching your workmanship, thank you for sharing your craft. I do have a question for you, you spoke about hot rolled and cold rolled steel. What does this mean to a machinist ? Is one machine better ? Thank you.

[@Abom79]

Not something I would try, but as I said, theres many ways to do the job, its just how you want to approach it.

[@TinShackVideos]

I've used nickel rod and Tigged cast iron before,held up well. On a marine exhaust manifold.

[@aryesegal1988]

Awesome job, Adam. Was wondering how you gonna line the two parts after you split it. Great way to go about this. :) Can't wait for part 2! :]

[@w056007568]

Making an accurate jig is a neat way of keeping everything together correctly.What was the marking fluid you used for showing your marks when laying it all out? Like everyone else I'm looking forward to watching part two.

[@Gloveman009]

Adam, that's a very cool project. I have not had much luck with slitting saws staying square so I am interested in your technique. Have you considered welding in a gusset on the back of the plate for support? Thanks for sharing with us.

[@Abom79]

Thank you. Part 2 coming soon!

[@oxtoolco]

Hey Adam, Looking forward to watching you whip a slitting saw through the pipe in the second half. What kind of handle do you have on your mill? Is it one of those lever type that you can re-position easily or do you have to pull it out and move it? Regards, Tom

[@krazziee2000]

nice set up

[@billdlv]

Adam your plan seems sound looking forward to part 2. I see you like using HSS scribes, have you used carbide ones?

[@donpollard9460]

I like the method!

[@Abom79]

Sometimes its easier OR faster to just lay them out by hand, depending on how accurate the part needs to be. This part is casted with slotted holes so I have some wiggle room. I actually enjoyed laying them out by hand.

[@marhue7026]

I like it, this is gonna be interesting, oh and i watch all your videos just never commented before. have been like forever.

[@davidtalley5051]

You did it the same way I should have

[@cryoburned]

Hey Adam, did you discuss with your customer possibly fabbing new flanges and making these risers from scratch? Seems like the 4 flanges are identical, just rotated. So 4 identical flanges and 2 pieces of 90* angle piping. Maybe if you got a plasmacam?

[@Abom79]

Thats what most people would do Im sure, but this customer is one of those guys who believes in keeping all the factory parts on the car. He wanted to use these old original pipes instead of making new ones.

[@awake.collective]

you do great work

[@toddadgr]

thanks for the reply like the video, been following youre thread on PM as well for a while now. Do you use the kool mist brand coolant with it as well? hows it work out on the lathe? Thanks

[@captainswjr]

How much better is that Dykem than a Sharpie? I'm guessing it's thicker and tougher. Could you have bolted the part to your lathe and turned it? I'm just thinking you could get some really nice "v" shapes by turning it, then bolt it up in your jig and do the welds.

[@toddadgr]

Adam, how do you like that Kool mist setup? been looking into getting one. Does it work well for cooling the cutter, as well as flushing the swarf out of say a slot that is being milled? Thanks

[@MrWaynepriest]

I am no mach as you are by any means,this is why i follow your great work,to learn from experienceLike i said,no pro.My idea would be once jiged up and ready to cut could you not taken an inch and half or what you were shortning.Take a rasp cutter that width and one cut it across,identical cuts both sides from one cut,,..What do you think,just thinking,without prejudice,,,STILL LEANING WAYNE THANKS....

[@2007markb]

As for the optical center punch, you can get a veritas from woodcraft for about $35

[@MatthewTinker-au-pont-blanc]

Curiosity, why would you have preferred cold rolled to hot, surface finish? Regards, Matthew

[@irrops]

How about clamping it in the vice as is and running a 1.000 or 1.125 end mill through it?

[@paradisevictor335]

what i was just thinking... slo mo steel cutting. seems like your the one who would do this.

[@dottiethompson4644]

Great guy with GET R DONE attitude... that is who I will listen too.. MORE VIDEOS..ADOM79

[@Abom79]

Got plenty to enjoy! 👍

[@oiadnz]

He used Dykem layout fluid, If you google Dykem, you will get their website.

[@oxtoolco]

Hi Adam, Sorry, the quill handle is what I was talking about. PM your snail mailing address. I have something to send you. Regards, Tom

[@andrekocsis2215]

Why didn't you just drill the holes on the verticle plate then cut it down 1.125" and after that you could have welded it to the horizontal plate?Then you have the correct height done and done.

[@bx2200]

How big a thread can you cut (comfortably) using the mill? Thanks.

[@Abom79]

Well I havnt ever tried power tapping a very large tap on the DoAll yet, mostly just the smaller taps. I'm confident it will pull a 3/4" and possibly a bit larger though with the right adapter to drive it.

[@mrhung9244]

[@beau8827]

Gaskets thickness play part in it ?

[@meyawabdulaziz3863]

hows the old saying goes ? measure twice and cute once ? is it ? thats what i fear about these kinda little projects is that after you have measured everything and then you start welding you might end up with it too high or too low...because of many things..welding gasket thickness like you mentioned even the thickness of the saw blade/ cutting tool have to be considered it has to be placed in the right spot what i would do it cut slightly less then grind it to size just in case...
