Isometric Drawing Basics: Sheet Metal Layout for Julian
ฝัง
- เผยแพร่เมื่อ 28 ธ.ค. 2024
- This is a simple video showing one functional way to begin drawing a sheet metal fitting or piece of duct isometrically in freehand and not to scale. It is something that is easily accomplished and is meant to give viewers that are wanting to improve their skills in measuring sheet metal adaptions 'on site'. This is in no way a video intended for those with any degree of experience and is not the way it is taught in trade schools or union apprenticeship programs. Its primarily a way to help someone intimidated by the demands of an industry that will come in handy when thrown into a situation that seems a bit beyond their ability. Start off small and build on it. Place equipment to be most advantageous to you as an installer and service tech. Measure what you know to be accurate and work from that point...and remember that a big problem is just a series of smaller problems stacked into one. Solve the little problems one by one and soon you will surprise yourself at your abilities.
Bear in mind not everyone has the ability to pay for HVAC training nor is everyone afforded the opportunity to enter into a 3 to 5 year Union Apprenticeship training program. For those that can and do have that opportunity, good for you....in my estimation that is the best way to go. But there are many, many others that find themselves thrown into the workforce without that luxury. There are tons of guys in the field that are great service techs that have never been involved in the sheet metal side of things but are wanting to expand their base of abilities. On the other side, I have friends with 40 years experience in commercial service and startup that wouldn't even touch tin snips for love nor money. I put myself in the 'untrained hack' category when it comes to sheet metal layout as I for one have had no real formal training. What little I know was learned on the job starting out with a small one man shop as a helper during my HVAC training at the local community college. When I got a better paying job in the big city I wasn't asked if I could install a furnace or fabricate ductwork. In the mid '70's and at $5.50/hour it was expected of us. So it was trial by fire and I was thankful for my previous employer allowing me to stay after work and play with his bench top lockformer and ancient 8' brake to figure out how to use the machines using scrap metal scraps.
Everyone has to start somewhere and as a retired HVAC service tech, I feel it my responsibility to pass to the next generation what little knowledge I have with the major caveat: Try instead to learn the proper, correct and accepted way through an accredited program, be it trade school or apprenticeship program. But if you find yourself in the situation where it is sink or swim, do what is necessary to survive the industry...it is a great career choice and expanding your abilities will have the tendency to make you more successful. Consider the basics in this video to only provide you a momentary 'stepping stone' in the proper direction...and that direction is formal training. Doing it the hard way is tough.
This video is specifically for a young man named Julian that posed some specific questions that needed a bit of an additional 'visual' answer. Hopefully he will find this video and benefits from what little it contains.
From an Instructor. You kept it simple and from what I see, you get an A+. Well done again.
Well dang, coming from a real instructor, I take that as the supreme compliment Duane !! Thank you sir. Like I told others, this is not to scale and not necessarily proportional. In the field when its your responsibility to get the job done, the luxury of time is not there to waste on an absolutely perfect drawing. I was hoping to give the young man an insight as to how to see what it is he needs to fabricate and in my estimation, an isometric drawing is what makes it 'jump out' of the page for you. Otherwise three views are required, front, side and top....and in tough ones, both sides. The isometric drawing eliminates that. At least that is the way I taught myself to measure. Thanks again for the awesome comment sir. Disclaimer: There are always exceptions to the rule....LOL.
You just made me a Julian #2
Excellent job teaching, I appreciate it. Thank you!
Well I'm glad to have been a bit of a help to you. Once you learn to draw your oddities in isometric form the layout really proves to be much easier to complete. At least that's the way I figure it. Btw, have you found the playlists above..? If you're into sheet metal, consider giving this one a looksee: th-cam.com/video/wAKLPMRhCOA/w-d-xo.html The good ones start down about 6 or 7 though.
44 brings back memories of 50s in High School and 5 and dime stores were great thanks for the trip
God Bless All

Wow Peter...Five and Dimes....inflation has replaced them all with Dollar stores....LOL !! I think mechanical drawing has been out of schools for a couple decades now....but I don't know for sure. Glad to meet you out here on 'Memory Lane' this evening. Have a great weekend my friend !!
Your explanation is done in a very understandable way. Thank you for taking the time to do this for Julian and the rest of us out there. There is always something to learn from every one of your videos. Keep it up!
He probably won't even find the video, but in case he does, here it is. Guys in the trades gotta get a toehold any way they can if they don't have the opportunity for formal training. I was an electrician in the Marines and that training plus the Community College AA in HVAC provided by the GI Bill got me started, but beyond a high school semester on metalworking, nothing formal in sheet metal, not even an apprenticeship. What's that they say...Trial by fire..?? Thanks for watching as well as the compliment.
Never learned this in school but I always manage with electrical drawings to get by and with your instruction, I`m that much better and that`s all I need.....CHEERS
Yes Gator, I've looked over tons of electrical drawings as well. You guys have so many symbols to memorize I go brain dead in no time. I don't know HOW you guys remember all that stuff !! Thanks for the visit my friend.
Hi Wendell! For someone who doesn’t do “how to” videos, that was an excellent “how to” video. You did a great job of explaining the basics of isometric drawings! Thanks for sharing!
Well, like I said it really isn't the perfectly proper way to do a drawing, but on a jobsite you've gotta get in there and get it done. I seldom if ever draw to scale when fabricating an item. There is no need and no time...IF you want to keep your job anyway. Now, if you are measuring for shop fabrication by some one else, that's a totally different story. A much more detailed and accurate drawing is required. The guys in the shop can't see what you are thinking unless it is noted and dimensioned on the drawing. Thank you Martin for a kind comment. I hope the young man finds this video to give him a little to think about for smoothing out his learning curve.
Don’t believe you would be considered a “hack” by any stretch of the imagination in most anything you attempt. Just watching your videos you would have made a great teacher as thorough as you explain things. Being able to convey a process is an art in itself. Good video, enjoyed watching.
Hahahaha....thank you for your kind words. I never thought it a good thing to keep things learned to myself...but not totally sure they are learned correctly so I like to add the disclaimer that there are many, many ways to accomplish a task of any kind. Thanks again and please have a wonderful weekend !!
I am a Civil Engineer. I had 3 yrs of mechanical drawing in high school and had to take it in college. You did good. Sketching is a very useful talent to hone.
Thank you Roy for the cool comment. A sketch makes it much easier for someone to see the intentions of the build and the exacting drawings are just not necessarily required for this kind of work. Julian was just needing a little push to get him started and hopefully this was helpful.
Wow excellent as always Tractorman! I agree isometric view helps me immensely to visualize any work or fittings. Agree drafting class in high school helped me and it’s probably possible to take a night class or online class if Julian finds one it’s worth it.
Thanks Roger, I agree with all you’ve said. A simple isometric makes it jump off the page right at you. Hopefully the young man will search out the training he needs to move forward into a rewarding career.
Bonsoir Monsieur le Tractorman 44 ! Great detail design informative about basic isometric drawing ; ) You are a great Picasso drawer Sir ; ) ho boy we are far from this ( In the mid '70's and at $5.50/hour it was expected of us.) Cheers !!!
Hoo Boy...Dave, that's funny. But wait, wasn't he the one that painted all the funny looking things as an 'Impressionist' ? Well I just do my 'impression' of a piece of duct by taking a nice, pretty flat piece of metal and bend it all crooked and out of shape into something I think it wants to be. LOL. But I am absolutely certain he was much, much better at his trade than I am at mine.... Thank you sir for always the enjoyable and fun comment !! And yes, in the mid '70's down here if a contractor paid you $5.50/hr you better prove your worth pretty quick or you were down the highway in no time at all !!
@@tractorman4461 In my mind you are a Steel Artiste Mon Ami and thank you very kindly for your fun Up spirits Sir !!! You do write down your bio trough your outstanding comments Mon Ami ; ) Cheers !!!
@@RCAFpolarexpress hahahaha.... I’m too lazy to put that much effort into something that would probably make the New York Times ‘worst’ sellers list of badly written fiction. LOL.
@@tractorman4461 You are very funny Sir LOL !!! No more snow for use since it is going to be up to 65f all next week !!! I think your writings will be a best seller Sir Cheers !!!
Thank you for sharing some knowledge OG , tin knocker bang the hardest!!!
Thank YOU for watching the silly videos I do Bryan. Aw, I guess there's one ever now and then that ain't to awful bad.....LOL Hey, if you get the chance check out this one: th-cam.com/video/i2KFLZGbZwI/w-d-xo.html and if you are REALLY serious about sheet metal, check out one of the playlists up above like this one: th-cam.com/video/PvDab537ul4/w-d-xo.html thanks for watching today !! (-;
Great tutorial . I learned hands on myself. Sadly schools seem more on BS ,then learning someone a trade. these days. Sorry for my late reply. Has always I Liked,shared. All my very best.
Thank you Bobby for stopping by for a Sunday visit !! European and Scandinavian countries are way ahead of us in tailoring education to the student. Many countries, as I understand it, require the kids to declare the basic direction they want to go in life in high sshool. Technical, medical, mechanical directions. Then schooling is provided appropriately. Now this is a very vague description of the process and not entirely accurate, but they do bypass a lot of frivolous studies. They get right to it !
I agree with you on joining a sheet metal union company. We had night courses on layout and fabrication paid for by the union to make their apprentices better. Some courses today for journeyman to improve their welding skills or blueprint reading. Very informative isometric tutorial. I'm sure if Julien applies himself to absorb the many different aspects of this trade he will be running jobs in the future. Thxs for the vids!
Yes, we have to be tested and licensed in the City and outlying counties and to keep the Mechanical Licenses, we have to maintain a given quantity of PEU's every three years. If your area doesn't have them, PEU's are Professional Education Units. So many core units that deal specifically with the trade, then so many elective units concerning jobsite safety, OSHA training and a hoard of others. We can even take college courses relating to the field and upon satisfactory completion will be reimbursed by the union. Even business courses are considered trade related as well as math of any kind.
We have a comprehensive facility that allows any member to come in after hours and burn rods, apply for a myriad of welding certs or learn one specific type of weld. We also have a comprehensive DDC controls training division as well. So many people do not realize the real benefits to being in the building trade unions. Thanks David for always the supportive comment.
I remember being taught how to do these drawings with an old drafting board and sliding T square. Also say what you want but as far as I'm concerned you're a sheet metal wizard!!
Yep...I too had the same setup in class. I really enjoyed transferring the dimensions to the top, then to the right then connecting them all into a 3-D Isometric in the top right. Wizard, huh.... maybe a wizard with a broken wand....LOL.
@@tractorman4461 lmao broken wand or not you do a mighty good job on all your tin work from what I've seen, it's a real art what you do! And them old drafting boards could produce a real nice drawing I still have a sliding t square and just need to cut myself up a new drafting board tho I've built all the coops n stuff on my property just with my own image in my noodle lol I gotta get back into the habit!
Awesome video thanks
Thanks Scott for taking the time to comment. Here's the whole playlist on the 2000 Ford: th-cam.com/play/PLk72G9DTzZ1ud7EttOd9HeA6diEdU2tU9.html. Just in case you are interested in the application.
A 44 Adventure with another cuppa Friday morning JO, which I toast your way! Supposed to be in the 60-70s next week and I have plans for outside more comfortable work, tutu perhaps,,,,,may be camo! I've been figuring out how I'm lifting a plow blade on my Craftsman that was for another tractor. It's the lifting that I'm working on, as its a heavy built blade probably 45-50 years old with very little wear. It belonged to a man who bought all Craftsman equipment. It's a challenge, which I enjoy but my Lincoln SP 100 ain't a werkin! I think the gun needs a new liner cuz i plum ain't gittin a spark much. New tip? Yep! But a small spool of wire that tangles a bunch. So I'm going to buy a 10 lb. spool that always seems to work far better than a small spool. I have a few weld jobs I need to do. Luckily my JOcup ain't steel cuz I'd be caca outta luck! Well, on all these heavy topics talked about, I need a refill and proceed with great and stupid ideas. A Fine Friday Friend Forty Four! From DaveyJO Holler to Yerz
Hey you know for the MIG wire they make a split-felt piece that clips over the wire and held in place by a little clip. They have a small squirt can of liner lube that you soak up the felt with and that keeps the liner in shape for a lot longer period. If you get a new liner, ask them about that stuff. I swear by it. Of course I swear at anything...even the hammer when it hits the wrong nail and I end up with a sore finger !! LOL Sometimes the lack of spark or poor spark is the ground clamp not grounding good too. Let me know if you get the kinks out it DaveyJO and for now, please have a wonderful weekend my friend !!
Well, you and I started tin bending around the same time!
Wendell, I have doing drafting for almost 50 years, starting in high school, through college, and now at my current job. Of course, now we use CAD programs, making 3D solid models, but until we had solid models, we use wireframes, which your isometric, or trimetric sketches depict. When I first started out in high school, I wanted to be an architect, but somehow got into mechanical design. Making a drawing using mylar pencils, or mechanical pencils, or putting ink on mylar, has become a lost art. I have a bevy of drafting tools, scales, templates, triangles, ink pens, mechanical pencils, etc. that I probably will never use again. With retirement looming in a couple of years, they probably never will be used again by me. I would like to get back to doing some artwork that I used to do way back in school. I had one oil painting go to state back in high school, but I degress.
BTW, since I have your attention, I picked up a 1944 Ford 2N. You wouldn't happen to have any Dearborn 3 point, 2 bottom plows, preferably 12 or 14 inch bottoms, would you?
I had mechanical drawing in high school, and that really helped me in the field many years later. I know you know some stuff about drafting !! I'm almost embarrassed to have you even see this feeble video....LOL. But what we each make our drawings for are WORLDS apart !!
Yes, I have a set of 2-14 Dearborn plows for the blue 2000 Ford....but doggone it they aren't for sale. Ain't that the luck.
On another note, I found a lot of water in the H rear end I'm working on and also two bad seals in front of the transmission and a bad bearing...(Video coming soon)....but you may need to check your H's rear end for water. Btw, there are drain plugs front and rear on these tractors. Let me know if you find water in there. I was shocked at mine and it was INSIDE the shed for months !! Had to be rain water from before.
@@tractorman4461 I have downloaded all the manuals, and even found out how much the rear end takes, which is 6 gallons. There is a plug that you removed, and when the oil seeps out of that hole, it's full. The transmission, differential, and the PTO should share the same fluid, if I remember correctly. I haven't gotten around to changing out the rear end yet, but that was on the list of things to do it. I already changed out the engine oil and filter. Someone had the wrong filter on it - the earlier H's took the long filter, this one had the short filter on it.
I found a few Dearborn plows at Coles Tractor, so I might be headed down that way today to look at them in person.
@@316jd140 good luck with the plows. Yeah, the weep plug is just below the clutch. But don't forget about the front drain plug..... Video coming soon.
Thank you
Start with the simple squares and rectangles, then move on to fancier fittings with angles and turns. Thanks for watching.
Hey Tractorman!
Hahahah....Hey R A !! LOL
