Really enjoyed this as it's what I remember. I used absolutely love gas welding. Really takes me back in time. Quite miss doing it.

[@trevsblog]

Thank you!

[@CulinarySpy]

Love ya work Trev, I've kept my oxy set for the past 35 years and now I realise that I finally have a good use for it to restore an old car in the shed.

[@Peter-V_00]

How to compress several hours down to 20 minutes, always the best Trev, you RULE!

[@markespinoza7090]

Genius. If you every come to a Southern California you have a place to stay just help me fix the roof on my Supercab Ford F-250. You are truly a Master.

[@matthewinga9546]

Attention to detail was fascinating. Finest work I’ve seen in a long time.

[@GregPalmer2]

Great work young Felah,glad to see old school oxy welding like i used to do,like you know there are always problems when you oxy weld,one being you need good access to the rear of the panel to fix the profile and its time consuming. I can still oxy weld and lead fill and its a pleasure to watch other people with the same skills,modern panel shops avoid these types of repairs because of time and the newer type cars haven't got thick panels to be able to oxy weld. Thanks

[@ibana8449]

So much to learn from this one Trev, radius the corners, and no filler butt welding. Quality

[@ab-bc2gr]

Excellent. Most clowns today use MIG welders. No rod is a sign of a really competent beater. I once watched my late father join a whole door panel with only gas and no rod. It was wonderful. Hope this trade will never be lost. Would have liked to see how you put (i presume) the lead in before painting.

[@andrewnichol1658]

You and matt are artist. The work you both do is beautiful. Much appreciated...

[@carlcorby3764]

Thanks Trev, great vid. You had me confused at the start of this vid as I am already subscribed to urchfab. Thanks for sharing the other channels!

[@MrCrankyface]

That fit is just amazing. Thanks for all your great videos and content!

[@ginfizz20]

Ah thank you and good job. I have watched many of your posts and you often talk about repairing a "wing". Today I found out what a "wing" is.

Thanks Tom 👍

[@nomad74777]

Awesome video! Thank you. I'm so glad i'm not the only one that still acetylene welds. I guess i'm old school but that's what I learned.

[@jh5881]

so impressed with your work and your personality...wish I was your friend and lived in UK... really appreciate your work

[@kevinhintz1903]

Very well done! With the advent of affordable MIG welders, few are aware of the old Skule oxy-fuel capabilities which have been done for a hundred years +! The real beauty of gas welded seam , it leaves the seam extremely malleable (not weak) but so workable! Great presentation!

[@CulinarySpy]

Great seeing the torch work, the stopping and planishing all makes sense now, I wondered why the old blokes used to do that!

[@Yelwas]

Just awesome to watch a skilled professional at work

Top work. Love that bead rolled edge tip...going to have to utilise that for a return lip in the near future me thinks... Shout out much appreciated Trev...👍

[@billnlori3149]

Love the cross promotion Trev!! I found your site when Matt mentioned you a few months ago. I have learned so much from both of you. These old school techniques are dying so its awesome to see them passed on!

[@nickpanico5441]

Thank you for your video . Sir you are a master of your craft . Be well !

[@markd2322]

Thanks for all the great information Trev. The explanation of the finer techniques are left out by so many others. The flame adjustment tutorial and aiming of the flame when the weld is made were extra informative i helping me understand what you were doing there.

[@paulerickson1906]

Dang! That came out perfect.

[@kensendelofski3761]

Reminded me of welding class back in the late 70s in high school. I always preferred using the torch over stick welding. To be honest watching a 6012 electrode melt away can get really boring after about 10 minutes. Thanks for the video enjoyed it. Also trigger was my favorite.

[@oldschoolgarageaust5261]

Perfection. Great to see perfectionist at work.

Beautiful work.

[@docfischer7291]

Found your video while searching what would be good to use for oxyacetylene as a filling rod. Unfortunately but fortunately with the defibrillator placed in my chest lots of electrical frequency is a no no. Thank you for the skill sharing . Just ordered a Smiths AW1. Can’t wait to play.

[@timgreen6522]

Trying to teach myself OA welding thin sheet at the moment so this was really very helpful. Lovely 'no filler' welds at times, still blowing holes at other times but generally improving. Many thanks

[@legendfpv]

Check your tip size

[@djpenton779]

Nice. I only have a flux core welder and an oxy acetylene rig. Now I am confident that I can do some planned sheet metal projects - with tons of practice of course.

[@trevsblog]

I’d definitely prefer to use TIG but there are a great deal of coach builders that only use Oxy acetylene. Many of them use it because the weld is softer and more workable. All of the hand built cars years ago were welded together using it. Cheers Trev 👍

[@djpenton779]

@@trevsblog Would you leave out the filler rod with TIG also?

[@trevsblog]

@@djpenton779 it depends how well you can get it fitting. To be honest I always use a tiny bit of .8 mig wire when I TIG weld. It’s so thin it melts and absorbs instantly. I like to use filler for aesthetic reasons as well as strength but it’s evident that many of the original coach builders didn’t use any as the undercut to the original construction welds is obvious. Cheers Trev 👍

[@SteveP-vm1uc]

Hey Trev, if you really want to see some car-fab magic, look up " PROJECT BINKY " . These two guys have created the unbelievable Mini. Incredible fab skills mixed with impeccable humor. You will end up going to the beginning and watching every episode.

[@jeadie8131]

How long did this take and how would that compare to the same repais if you used TIG? A video with identical parts repaired with TIG and Gas. perhaps left and right fenders, would be great to see. Thanks!

[@geeper2142]

The weld was still slightly low ,did you use high build primer or a skim of body fill ?

[@philt9246]

You are 1 bad dude

[@burtreynolds3143]

never seen anyone do a sheet metal repair with a torch ...... plus no filler ! I am going to try that tomorrow and see if I like it better than MIG which leaves those weld lumps.

[@curtispooler6497]

Just how I put in mind with mig

[@snowflakemelter1172]

I can't see how gas is better than TIG for this. TIG brazing might be less heat distortion ? ( never done it though )

[@looking_33]

The difference between this video and the second one in the list by “MY FRIEND PETE” is astounding. You treat this like an art, near perfect results, with no bondo. “MY FRIEND PETE” told me to make a flange, mig weld and cover with bondo. Results may look similar but this is obviously the proper method! I think I’ll buy tig instead!

[@trevsblog]

Butt welding is certainly preferable to lap welding but both methods have their place. It’s all about experience, cost and how quickly you need to get things done. I’m very much trying to perfect the art of coach building and restoration and I’m also now not doing it to earn a living, so it now doesn’t matter to me how long something takes. Many people making videos have been caught in the trap of having to get things done in next to no time at all so they only learn one way of doing something and that’s what they show. Cheers Trev 👍

[@leslieturner8260]

how do i get to that music it is amazing. great vid

[@RickRose]

Fine work. I just got directed here after watching you do a TIG demonstration. Do you think you'd prefer TIG for this application now that you've become handy with it?

[@trevsblog]

Rick Rose I don’t do enough welding to make a real balanced final judgment on this, both have their own characteristics. Some top coach builders will only use gas full stop, but is this because they don’t want to learn another technique, I really couldn’t answer that for you? My preference is currently is definitely for TIG. If you gas then things tend to end up more malleable but distortion is increased. I’ve never learned to gas aluminium properly so I cannot comment on those differences. Cheers Trev 👍

[@chrisjackson9102]

What, no plug for Bad Obsession Motorsports and Project Binky? They also refer to us as "colonists".

[@camaro19690]

Wow,great work learned a lot.How long would that repair process take just putting in patch panel and welding it? Just curious thanks for all the lesson ,just found your channel yesterday.jason

[@trevsblog]

[@groovedodger]

Cheers Trev great job on that wing. Whats the advantage using gas welding over Tig ?

[@trevsblog]

groovedodger I’d actually prefer to do TIG but gas is slightly softer which is preferable as far as welding goes but I’d rather TIG any day, this was done mostly to show asa demonstration. Cheers Trev 👍

[@jmyers9853]

one thing i have noticed is how clean you make the metal before you work on it.

[@raymundsantos2324]

Hi! I have a question, why does the torch sometimes pops when welding panels with filler wire? Thank you!

[@trevsblog]

The oxygen acetylene mix is extremely volatile. Welding can cause pockets of unburned gas which then ignite with a pop. Another really common problem is having a leak where the nozzle screws into the torch, there is an O ring there. When you’re welding sparks fly up and ignite the gas at the nozzle leak, again causing a small explosion 💥

[@raymundsantos2324]

@@trevsblog thank you very much!

[@kanishkaranasinghe4405]

Great video! Why gas welding and not TIG or MIG?

[@elaineyare6580]

very enjoyable try number 1 nozzel it,s better

[@timgreen6522]

Recently been OA welding repairs on my 1928 wings and although I got there in the end (having watched this video many times for inspiration in the four years since I first commented) I still struggle to get a soft rounded flame like yours appears to be. My flame, although small, is pointed and quite aggressive and I have to be super quick to avoid holes and I think I'm making progress harder for myself than I need to. I'm using a #1 nozzle but can't seem to get away from the pointy flame. Any other tips (if you'll forgive the pun) greatly appreciated.

[@trevsblog]

Hey Tim this can only be a torch or a gas problem. I’m 99.9% sure I used a #2 nozzle. Are you using pure acetylene or a mix? If you’re using a mix this will definitely affect the result. If you are using pure acetylene then I’d definitely consider trying out a different torch. 👍

[@timgreen6522]

@@trevsblog Thanks for coming back so soon. I'm using straight Acetylene (and Oxygen of course) I must admit that I don't really like the standard torches that amateurs like me tend to buy as it just too clumsy for the thin metal sheet bodywork that I do most often but there is not a huge amount of choice on the market and the nifty little Cobra (?) jobs seen in the USA aren't available here I think. Also, do you modify your nozzles to get them closer to a 90 degree bend? The slight bend on a standard nozzle means that you have to have your arm up in the air to get the flame angled down. Sorry for the long response.

[@trevsblog]

@@timgreen6522 no I don’t modify the bend and yes your arm is cocked a bit too much. Why don’t you try some larger nozzles first, this would be the cheapest and easiest change you could try. If you think about it a larger diameter nozzle will work less hard to generate the same heat as a smaller one which may well generate a less ferocious flame as you can back off on the amount of gas you have coming out the end. Try a #2 first. Raise the acetylene until the flame starts to flicker lightly on the tips then introduce oxygen. If the flame is too hot turn the oxygen down slightly then bring the acetylene down to correct the flame if it’s still too hot repeat the process. I’ve actually welded using a #5. I’d personally start with a #2.

[@timgreen6522]

Thank you for that. I hadn't thought of it in those terms. I'll give it a go.@@trevsblog

Great workmanship... do you still use this welding or it's all TIG now?

[@thinkerdoit]

Trev! Following for a while, cant say thanks enough for your time, energy and video quality! Have a question. @ 38:52 ...before you put the paint on...Im seeing some small pits left over. Did you go back w a gas weld and filler? How do deal with this, in body prep? I get that you planished earlier but i still saw tiny divots in the lighting. Noob here, u remind me of a mentor I once had.

[@trevsblog]

fancypants 38:52 is the end of the video. I think you’re referring to weld under cut. Where the weld area looks pitted, this is because it is slightly lower than the steel around it. The demo was really to show how the old time coach builders used to weld panels together without filler rod, many of the hand built cars we work on look like a patch work quilt once you get under the paint. This was smoothed over with a skim of filler during the paint preparation stage. Many people go to a lot of trouble trying to disguise where they have welded, myself included because it just looks so much nicer, but back in the day they really didn’t go to as much trouble, once the paint is on you cannot tell the difference. Modern paint processes give us the impression that theses cars looked perfect but in fact they looked very wobbly compared to today’s expectations. Cheers Trev 👍

[@thinkerdoit]

Trev's Blog sorry i meant 28:40. But i believe thats the patchwork you referred to? So in the good ole days, they didn’t fill but just painted over it? The primer and sanding was enough to hide the pits?

[@trevsblog]

fancypants they didn’t have fillers but they used lead if the joint required it. I suppose it depends how far back in history we go, the earliest cars were basically a horse drawn carriage minus the horse, wooden wheels and brush painted with oil based enamel paints.
