🔥DIY Cutting Guide

[@HulberkArmor]

“Look at thaaaat, get ya sum” lol. Listening to Bob talk and not taking things to seriously is what makes this. Full of knowledge as well.

[@williamtiebout7992]

As always, presented in a calm, cool, straight forward approach. It show you are an educator, well done

[@wailnshred]

I agree, he's a good teacher.

[@chrismclean8211]

I love the way Bob spoke as he was teaching. It really emphasised the methodological and deliberate nature of every step of his instructions. It kinda reminds me too slow down and do things right the first time.

[@loadpin]

Another great how to video Bob. I completely understand why you don’t have plans for the burn bars, a lot of the younger welders coming up will learn that “ necessity is the mother of invention “, especially when they are out in the field and need a quick tool or simple welding fixture that they can piece together to help with their welding project. Thank You Bob, Keep up the great videos.

[@billythebake]

loadpin - heck, I don't know why folks stop at asking for prints. What about requesting a 3D model? I mean, if they can't look at it and see it's a piece of angle with a piece of bar stock stuck to it, perhaps they aren't ready for a cutting torch...

[@loadpin]

The Carfarmer Shoot that’s a good idea, let’s ask Bob to do a 3D model of the burn bars, I kinda know what his response would be, and he probably couldn’t say it on youtube🤣😂🤣😂🤣

[@billythebake]

loadpin - maybe he could provide data files so we can have them 3D printed... (facepalm)

[@loadpin]

The Carfarmer 🤚🏼

[@melgross]

A great idea. But, sigh, when you’re not in the trade, and live in a city, you don’t just have pieces like that lying around. We have to buy them. That was about $25 worth of metal for a lot of us. It may not seem like much, but to some, making something here and there, it is.

[@gratismedia6574]

I cannot express enough gratitude, in how much you are getting me through welding school..thank you sir!

[@larrysperling8801]

as a millwright i built and used burn guides about 50 yrs ago ya i'm old. we seldom changed the tip size so we would find an angle that we could attach to the main body that you could rest the tip retaining nut on to give you a constant standoff distance. we never used acetylene ,too expensive. nat gas in the shop and propane in the field. great videos.

[@donsmith9081]

Exactly (on top)

[@WTFChuk]

Excellent tutorial as always, Bob! I use virtually identical burn bar as yours, except I don't have handles on mine. I think I will put a handle on one to try out. :-) Also, I have some that I have deliberately made from heavy material (i.e. 3/8" thick angle) to use good ol' gravity to keep them in place. A couple things to mention that might help some folks: Many fabricators, especially hobbyists, may not have access to a milling machine without having to pay someone. While hot rolled flatbar is normally reasonably straight, using cold-rolled 1018 flat material will usually give a very straight edge without needing to be machined. Just don't do any more than the tack welds that Bob showed to avoid warping it. Another tip I have is that there are collars available for most cutting nozzles that clamp on to the nozzle and set atop the straight edge to hold the nozzle at a constant height from the material being cut. Finally, if cutting with alt fuel gases (propylene, propane, Starflame C/Chemtane 2, natural gas, etc.), the nozzle needs to be between 1/2" and 1" from the material being cut. In that case, instead of welding a piece of flat material to the big angle iron, get a piece of 1"x1"x1/8" or 3/16" angle and weld it to the big angle "standing up" and out, so now you have a guide that is 1-1/4" off the material being cut. This, with or without a collar, will be at a suitable height for alt fuel gas cutting. If 1" angle isn't straight enough, and a mill isn't available to straighten it, a piece of 1" CR flat bar can be welded to the top of it to be the needed straight edge.

[@rmschrader36]

"I hate it when it does that"......classic!

[@jensonhartmann3630]

That's a Top Gun one liner lol

[@Whipple1]

. Thank you Bob. I intended to make one of these tonight in my shop. Couldn't be better timed. Appreciate your videos. Cheers! Whipple

[@bossmonkie]

I made a similar guide and I put a washer on the cutting tip to keep my gap consistent. I am able to make cuts so straight and clean this way it's hard to tell it was torch cut.

[@gregkellow4723]

Great build. I have flat stock that I use. But after this I think I'm gonna add a spacer. I wish my old boss was watching. He tore me a new one on my first day of work for using a cutting head for heating material. I never saw the harm, but it was his rule. We always had to switch to a heating tip.

[@benjamincullifer165]

That's cool. We do a lot of plasma cutting at work. We just use a piece of 1/2" x 2" flat bar, you know, however long we need. Keep em' comin'!

[@Iowahurler82]

With the tips we have on out plasma cutters, 1/4" lets you run a lip of the tip right on the steel. Unless you fall off, you will not get into the material you are cutting.

[@pieshka4509]

"there's really no plans" describes so many random things I've made around the shop at the spur of the moment and improvised as I went. Except the spool holder and deep shelf I had to make to put it on, I actually had to draw those out

[@dmr400]

I've really been enjoying your teaching style Bob, especially the stick welding side of things. Have been waiting to see a good video to say thank you on, and here it is...Hello from Klamath Falls, I live about 5 miles from Columbia Plywood. Small world.

[@Walaboro]

Fair amount of free hand cutting as an apprentice welder. Ive used guides with magnets and it feels great when they tip over doing a 1 1/4 thick plate cut. Thank god for low hydrogen and sanding disks, besides, "its not critical" XD

[@larrywallace3637]

Great idea. American ingenuity at its best! Thanks Bob.

[@johngroberts952]

I made one of those after I saw how well yours works. Now I am working on a whole fleet of them. Thanks Here are the plans, --make to size--.

[@lloydprunier4415]

With my nerve problem and my love of coffee I really need to try some of these!

[@bradblake9642]

Bob it works great I through one together after seeing you use one in a video. After you pass the 50 mark it take the shakes away lol.

[@larryelliott1417]

like your cutting guide...the older i get ...the shakeyer i get......just suggestion only......what about adding a flat strap rail standing up on edge for the tip nut to ride on, adding a little more stability for us oldtimers......thank you for sharing ....big fan of your videos and opinions of our trade.

[@JuanGarcia-ob5uh]

Bob, awesome video, I'll have to make three or four of them for different size cuts. I'll also make a couple of rings to hold the torch head at a 90° or 45°, or 37.5° and 22.5°....thanks again

[@charleswashington2126]

I've been curious bout those. Thank you Mr. Moffit.

[@drumtwo4seven]

Would you have to make something like this for a plasma cutter as well or not as elaborate?

[@rtkville]

I've thought about making one of these for a long time, I think you just pushed me over, perhaps I'll get it done! Thanks!

[@donsmith9081]

I use a pc of angle but slide the torch tip nut on top of the vertical part. That holds the torch at the right distance above material while also guiding left to right.

[@chrisbeard2869]

Thank you for this video bob, I’m taking a intro to welding course at my community college on saturdays. I’m going to try and make a burn bar as one of my projects.

[@stevecarlson5944]

Thanx Bob, Sometimes the most obvious, Isn't....... Awesome trick

[@billschuman598]

Hey Bob: Nice I was getting tired of holding a piece of flat stock, it usually moved or just got hot..

[@andrewrobinson2869]

Hi just wondering I bought myself a 100 amp gasless mig, due to $ issues. I am finding it really hard to do any type of a decent weld I take it if I had a better machine I would do a better job. It seems like my stick welding is much better . I am 57 so had my stick welder for 30 years don’t have much money . What advice could you me regards Andy Perth Australia .ps love your channel.

I dare you to put a square up to those handle bends haha. Good stuff sir.

[@Matcatgwp]

Really like the videos Gotta make one of these for the next project

[@johngardom]

Good idea workes for me I tweeked it....by adding a 1' x '3/16 or so flat bar to the length of the inside of angle iron ( handle side) will give you a nice but fixed bevel guide. You will have to adj. measurements per your tourch.

[@Mr215Alive]

"Get ya some!" Thanks for the picture at Fabtech. Say hi to camera guy.

[@joshgodwin6288]

Another great video Bob. I have a question related to torches. My neighbor and I share a lot of tools, especially more expensive stuff like welders and torches. I am a diesel mechanic for my day job but i am a weekend warrior when it comes ti metal fabrication. I borrowed my neighbors oxy fuel rig to do a little project (modifying some hinges to bear-proof my trash can) and he commented on the rising cost of getting bottles refilled. I said i have seen propane used for fuel as it is much cheaper but i don't know the pros and cons or how it would be set up. Would you be willing to address the topic of alternative torch fuels?

[@kf8575]

Propane, butane, or MAPP gas are all ok for heating and cutting, good for brazing, but no good for gas welding. Dont get a hot enough flame

[@the_millwright]

Love the millwright shout out 👍🏻

[@joebriggs9599]

Thanks I will build one and give it a try.

[@mongomay1]

Do you know Warren in Klamath Falls at Western truck tractor Service?

[@dakotadavis5462]

I push the torch to keep my heat in front of me plus in scrapping u xan lay the torch parallel to the metal and cut 3x as fast

[@warrenwilson7572]

You should do some I beam cutting. Using you burn bar. It would be appropriated. Thank you for your video s.

[@bjen2005]

Nice straight edge guide. Do you have any recommendations for making a guide that you can use to cut a bevel on a piece of pipe other than a metal lathe or pipe beveler? Trying to make a move and get into pipelining.

[@bobmoffatt4133]

Pipe beveler

[@Iowahurler82]

Yeah, not really any decent hand made rig for that I have seen. Unless you build one for each specific size pipe.

[@bjen2005]

@Chris Hurlbut -- That is what I was seeing as well. Been weighing the option and I think a lathe would be more beneficial for me at this point since I can bevel pipe and make some tools along the way. Hopefully, I can make enough on th side with the lathe and purchase a pipe beveler later on.

[@GosselinFarmsEdGosselin]

Really Bob??? Did you really just flip us all off????!! LOL 😎 I've never made any guides like that, I have made a few rolling guides, not just circle cutters... I've got one that I made, probably 35+ years ago, it's two wheels made out of 1" roundstock and two adjustable cap screws with the heads ground and polished on a curve. It was the cats meow for cutting tractor wheels to widen or narrow them!!! Made one out of an old horse shoe and three bolts for the same thing. Good video, as usual! Thank you!!

[@spurndirty9546]

How close to the line do you put the guide when using a torch?

[@bobmoffatt4133]

Depends on what side of the line you want to cut.

[@jeffgardner5302]

These are awesome, thanks very much for sharing, goin to the shop to build a couple, thanks again

[@barryw9480]

Long way round. Use a smaller bit of angle and run the nosle bolt along the edge.

[@brianbowman5402]

I like the gap under edge. How about two pieces of angle stacked together? No alignment needed.

[@Iowahurler82]

The issue there will be the radius with the inside corner and the sharp outside corner. Could work though.

[@customhaines2510]

Not a bad idea for small guides, but keep in mind the extra weight if you need something bigger. Also costs more, even if it is a cutoff.

[@brianbowman5402]

@@customhaines2510Use two short end pieces for the lower part if weight or cost is a constraint.
