It's fascinating to see this build take its final form-congratulations! The sight of the newly-mounted badge prompted me to think of the following Bad Idea: buy a lug-lining pen (which takes a small amount of paint) and use a dark-colored self-etching primer to outline the logo for a bit of decoration 🎨

Came out killer!! Nice brazing setup. You got to think of brazing as if you are gluing the part together since it is a form of soldering. Turn the torch down and use circles in the area you are soldering to control the heat, big circles for when it is too hot and to preheat in the direction you are brazing and small circles for adding heat to the area. When you lift you are creating stress areas from the heating and cooling of the area. Want to keep it a constant temp.

Hi Steve! First of all: I really like your videos and admire your work. I ride a cargobike myself for decades. What I do not understand in your design is that you connect the front rack to the front wheel instead of the frame. If the weight does not move you will have a stable ride. With weight you easily oversteer and start wobbling. A fixed rack is commonly seen on modern cargo bikes.
@PithyBikes 7 жыл бұрын
+Bas 't Hoen yes its true! I noticed that cycle trucks has an integrated front rack design for that reason. I dont really have a reason for not doing that too. I suppose nothing too heavy will be on that rack but you never know.

Beautiful work. When bending tubing I find it quicker to, rather than trying to hit the bend exactly, overbend by two or three degrees, remove it from the bender, then take the bend back to 90 deg or whatever. Dealing with springback is a PITA.
@PithyBikes 7 жыл бұрын
+blipco5 yes i found myself having to bend it further because of deflection. The nice part is that this bender is forgiving of you need to load the tube back up again.

Hey! I've been enjoying your videos. Please consider adding either another attachment point on the front rack (such as to the brake bosses), or a strap between the rack's loop (the one in front of the headtube) and the handlebars. That plate you have attached to the fork crown could easily break when the rack is loaded, resulting in the rack rotating forwards underneath the front wheel and a nasty crash. It happens!

You didn't opt to drill any vent holes for your brazed joints? I've found that leads to porosities in the brass.

Expanding air pushes the brass out or holes in it.

Yup, exactly. It's especially bad if you then powdercoat the rack, because you'll get nasty bubbles and holes in the coating around the brass filler, when the part is heated to 400°F in the oven.

If you don’t mind me saying, there’s *one* thing I might have done differently: the placement of this cable guides at the 7 o’clock position on the tube... slightly risky? I’m sure there was a reason why you put them there...
@PithyBikes 7 жыл бұрын
+Richard Hayter no worries! I love feedback! I didnt really have a reason other than it seemed like the best place for the least cable resistance. Should i have tucked it under more?

@benturner190 7 жыл бұрын
Brazing, especially with silver makes more sense for the smaller jobs such as the cable guides because it is very easy to create a low profile joint that requires minimal clean up to look good. I am a frame builder too - although i braze everything (with brass and silver)
@johnpossum556 7 жыл бұрын
Not sure exactly why he picked brazing but usually it is a matter of strength and convenience. Brazing is between soldering and welding both in convenience and strength. IE: Brazing is weaker than weld but stronger than soldering. It also takes less heat & less time. It's really a lot like soldering on steroids while welding takes a LOT of heat.
@benturner190 7 жыл бұрын
Brazing is not weaker than welding, in fact you are more likely to weaken a frame by tig welding due to the higher heat from the welding changing the properties of the steel.

@honorharrington4546 7 жыл бұрын
Your lower form being wood was the problem in shaping your badge. You should have put the butt joint at the rear of the rack where your flat metal bracket could have reinforced it. Next time you butt join tubing use an internal sleeve for strength. Remember, the first 10 to 20 frames are practice.

@Mad-Duk_Machine_Werkes 7 жыл бұрын
also Braze isn't suited for butt joints where you file and sand away all the brass.... it's stronger as a fillet material with a bead like joining pipes 90* to other pipes - Also WAYYY too much flux you're using, esp. since your steel is starting out so clean and new anyways- you're making too much work for yourself cleaning all that afterwards

Was there a special reason for brazing instead of welding or was it just that you wanted to get better at brazing? Btw, the bronze brazing looks very pretty :) I don't know how steep the hills are where you live but as a BMX Racer I would recommend a bigger front chainring for more speed ;) I don't what you're currently running on there but I have 44 to 16 on my bmx and you can ride that pretty much up every hill, but that's something you will have to decide ;)
