MAKING STAINLESS STEEL BOTTLE CAGES
I have been hesitant to post this video. It has been edited and sort of ready for a while but the bottle cage making process has developed a lot since shooting these clips and I'd rather show how the newer version of the cages is made, but I won't have time to film more cages being made right now because I have some frames to make. I might film next batch and upload an updated version. We shall see.
If you are here for the jokes and fancy graphics I am sorry to dissapoint.

Making a fillet brazed steel bicycle stem!
zhlédnutí 13KPřed rokem
Watch me chop some steel tubes and glue them back together using fire. Things used: - T45 steel alloy from proformancemetals.co.uk - SIF 101 bronze filler - Bicycle Design LFB flux BAG MAKER witslingers.com/ witslingers
You Can Buy Tube Benders?
zhlédnutí 1,8KPřed rokem
Questionable use of lathe and milling machine ends up becoming a surprisingly functional tube bender for 8mm steel and stainless steel tube for racks and other bike related components.
Really nice vídeos, man! ❤
Just what I was looking for. Appreciate you sharing this!
Bro make more videos, These are beautiful.
I'll do my best. Got a lot of money making projects going on simultaneously so CZcams has been bot been prioritised lately 😊
Fabulous
Just fabulous. What size torch are you using?
Thanks man. The torch is an old AGA X something. Not aware of its size. Could be smaller for sure but its great quality so I'll live. The nossles I use are 1mm (160L), 1.2mm (300L) and 1.5mm (500L) openings. Not sure what that equals in "size" or other makes.
Ohh yeah and its 1mm tip for the bottle cages probably. But any of them would be alright
What filler material are you using?
Sif 101 bronze rod
What model finger belt sander is that?
It's a Proxxon. They make an aku battery one and then this on a cord. I can't recommend cordless. I have modified mine a lot and prefer this over any other I have tried as it's very silent compared to compressed air-ones and because it's super light. It's not very good quality as you'd expect from a hobby tool. But I've been able to to repair and keep mine going since 2014.
nice! what type of solution are you using for electropolishing?
Phosphoric acid
Thank you for sharing. Your videos are very good - please make more !
Thanks man. I'll do my best to make time for them
need to get me some cages for sure
<3
Quality video, quality products
Awesome work as always. Much love.
Appreciate it 🙏
lfgss represent. great to see you still making top-notch stuff, even tho i don't go on there these days
Thanks man. Lfgss is still my sacred space 🚀
P R O M O S M 💯
Love your work and videos, super inspiring. Id love to make my own rack, Do think it is possible to braze a rack using a mapp gas torch?
Thank you very much. If brazing with bronze filler you'd need to get the tubing up to 870°c ish and I'd think that would be hard with mapp. I haven't tried. If you used silver you only need 550°c and that could be possible, but you need to practice a lot to be able to create fillets with silver without it running off the tubing. I've made a rack once using fillet pro (which is sort of like using silver) and my fillets were too small and the rack failed after a couple of years. So, I'd be careful not doing a front rack as the consequences are severe. I am considering doing rack workshops (and balance bike workshops) where you join me for a long weekend and bring your bike and then we makes some racks together. Haven't gotten around to doing the math yet, but would be a fun alternative to a framebuilding course I think.
That's super helpful, I think I'll hold off in that case as I haven't the space for a full oxy acet setup. A rack workshop sounds brilliant, I'll keep an eye out. Bottle cages look great by the way!@@hulsroy
@@TandemUK thanks man
Lovely stuff
Another great video! please keep them coming
Yes boss
Love your videos !
Thank you ❤️
Excellent video
Sangat bagus pak pengerja an nya.saya suka sekali...👍👍👍🇮🇩
Sweet stem and wonderful camera work. Thanks for your Video!🎉
Thank you
I really enjoyed your videos. They are inspirational. I would love to see more videos coming.
They are coming I promise. I have part 3 shot already. But I am trying to launch this company of mine while also doing my best of being the dad I want to be.... so you are gonna have to be patient with me ❤️ But thanks for your kind words. They are the motivation I need.
thats a lot of hours by the look of things .
Inspiring content, looking forward for part 3...
Thanks man! I know it has been a long time coming. I got the footage for part 3 but haven't been able to find the time to get the editing done
What crmo tubes did you use, for the barclamp? 35mm x 2mm which you later reamed?
T45 steel size 1.375"x0.065" from Proformance Metals I believe. ID is 31.7mm and I ream that to 31.8 gently if needed.
Surprised you didn't use a slitting saw to cut the relief cuts.
I just bought one last week actually. I have only done one stem a year previously so never felt the need, but now I have more stems to do it made sense to speed things up.
That hole saw drill thing looks wonky AF
That because it is/was. Paragon Arbor and better hole saws on order.
@@hulsroy but does it matter anyway? Since I guess you could fix it with some filing? Or is it better to but straight and not worry about filing?
In this case the fit was good. Hardly had to use a file. But miter was also from a smaller tube to a larger tube which is more forgiving. The arbor was trued for a different holesaw and I have been waiting for a paragon Arbor for a while anyways. Will be good with a more steady cut
Exellent. Loved the dad jokes, too!
Loved it! As someone who fabricated an integrated rack on the stem relying only on the four front bolts this is a better approach as it removes a lot of the leverage effect.
Thanks for your comment. I'd like to see your work if possible
Excellent, cant wait for part 3! The rack is the part im looking forward to most!
How many hours do you need to do something like this stem? (including design)
That's a hard one to answer. One of my future videos will be drawing up a bicycle frame and forks in Rhino. That will give a view into my design process. The stem and rack is for Wit Slingers and there has been a lot of back and forth. I didn't keep track of the hours. I think I can make a stem in a day. Here I was filming and machining special bits which you could buy and save time.
Old school process! Oxyacetylene brazing is an art. I've been doing it for nearly 40 years, then tried GTAW silicon bronze and was amazed. The temperature increase was the hardest to learn. Longer arc is actually more heat, less concentrated. GTAW is constant current power supply with voltage being proportional to arc length so longer arc is more power. Inner fillet and complete joint wetting is important so I would use flux, at least on the first pass. Second pass can be a stack of dimes or more fluid, all a matter of puddle control. There is no way to stack dimes with 55% silver, that flows like water.
Yes, also a very nice process to use. I used CuSi3 a lot and it's a great and forgiving material for a lot of applications.
super nice. may i ask, why your flame is bigger while brazing silver than while brazing bronze? (at least it looks like this)
Well, it looks bigger but it's less "hot". I back off on oxygen when doing silver instead of having a neutral flame. It's just something I have picked up along the way from somewhere. I can't remember the actual reason and there might be other ways of doing it but I works well for me.
@@hulsroy i dont think your flame is that neutral when your brazing either ,,, but most folk online dont braze with a true neutral flame , the guy who taught me to braze over 45 years ago would have a fit if he saw me with a flame like I often see .. try adjusting it a bit ans see how it goes
@@tomthompson7400 thanks for your comment. I feel confident I am using a neutral flame when brazing, but filming at the same time and that can obviously make things a tiny bit sloppy. I will make sure to check up on my process and maybe post a new video with more focus and close ups of the flame!
@@hulsroy try with just a Tad more oxygen and see ..even if it's only on a scrap piece...but unless it's a trick of the camera that's not a neutral flame at all .
@@tomthompson7400 well the footage is definitely not perfect in terms on conveying what I am experiencing, but there is always room for improvement so I will have a look at my process.
Another lovely video! I hope your thumb is feeling better.
Nice and inspiring video! Which lathe and tig welder are you using?
Tak! Lathe is an Emco 8 replica from China. TIG is a Migatronic Delta 160 DC
I like your musical choice!
Biked and subscribed!
Helt perfekt. Tusind tak
This is great 👍
Thanks Paul 💖
