Custom made crash cage?
Has any one ever seen or made a custom crash cage. I'm a fabricator and I want to make my own stunt cage. I don't really like the design of the 905 or sick innovations.

Re: Custom made crash cage?
Ya. YouTube has a sweet video on there...they used springs for shock absorbers.. painted it.looks good and easy..... .. search it...
I'm a pipe fitter ... Il be fabricating a subframe as soon as I get time off... saves a lot of $$$... good luck

Re: Custom made crash cage?
Cool man I'll check it out. Hey what thickness size of metal were you thinking of using? I want to start making the subcage stunt pegs. They look rediculousely easy to make and they want $200!! I can make them with under 20 bucks! But idk what thickness to go with.

Re: Custom made crash cage?
For the pegs...probably buy some actual bmx pegs and go from there... sounds fun...and easy...let me know how it goes....
Also any framing on any toys should be tigged out.... u can stick weld them too but tig is definitely stronger...
Good luck

Re: Custom made crash cage?
Every cage company started off in a garage, most are still there. If you have some ideas for one, make it. I used to make them for my stunt bike way back before you could just go buy one. Now id rather buy one cause my time is more valuable than the money id save just making a 1 off.
Let me give you some **** to think about:
Avoid having the impact points tied straight to motor mounts, like early cages had.
Be sure that both sides of the cage tie together with a good solid bar or better.
Use DOM for anything structural, not pipe. Ralph, you know better!
The main hits will happen towards the bottom half of the cage, but dont make it too low or the bike will roll over onto the handlebars when its on the ground.
There have been hundreds of threads about cage building over the years. Lots of info about what worked, what didnt work, and what banged up your shins. Spring loaded sliders, spring loaded cage arms, spring loaded frame mounts, most of which worked but is too expensive for an average stunter. Do some reading.

Drawn Over Mandrel (DOM)
Strong and well-finished DOM is an electric resistance welded tube tested for soundness of weld and drawn through a die and over a mandrel. This process imparts significantly improved mechanical properties to the tube, due to the cold working process. It is considered a high quality tube, and is normally constructed from SAE 1020 or 1026 steel. Note that, technically DOM refers to the process by which the tube is finished after having started as an ERW tube. Technically, DOM is not a type of steel tube, but rather a process. As so often happen though - in common use the term has become accepted to mean a specific type of tubing rather than a process. In this case, when people say "DOM" they normally mean an ERW tube drawn over a mandrel at (close to) room temperature and made from SAE 1020 steel. It is normally drawn to O.D. and I.D. dimensions. Here is what the Steel Tube Institute of North America has to say about DOM:
The DOM Manufacturing Process
The manufacturing process for DOM tubing begins with coils of steel, which are slit to the proper width for the desired tube size. The strip is cold formed and passed through an electric resistance welder which joins the edges together, under pressure, to complete the tubular shape. After testing the weld's integrity, the tubing is cut to length for further processing.
The cold-drawing process creates a uniform, precision product with substantially improved tolerances, surface finish and tensile strength, increased hardness and good machinability. In this process, the tube is cleaned and annealed, and one end of each length is squeezed to a point so it can be gripped by the drawing mechanism. The tube is then drawn through one or more dies and over mandrels. This reduces the diameter of the tube and thins its walls to the required dimensions in a controlled fashion to provide the qualities desired in the finished product. Metallurgically, drawing improves the tube's concentricity, tensile strength, hardness and machinability. Close dimensional accuracy is achieved through tight control of both outside and inside diameters.[10]

So I imagine it's available at any pipe yard...? Because if it's machined specifically it means more $.. right?

Re: Custom made crash cage?
This is a picture of the exact one from Impatech that I want to make. I found out its a 1" tube and it's 0.120 thick. From what I can tell in the picture,it looks like the pegs are 1" and the other tubes around it are smaller. What do you guys think? How big are they? Oh and don't worry Impatech! I'm not gonna copy your design exzacly! I'm gonna make it better

Re: Custom made crash cage?
I would go with std (standard schedule 40) just for the subcage .
For the pegs...probably buy some actual bmx pegs and go from there... sounds fun...and easy...let me know how it goes....
Also any framing on any toys should be tigged out.... u can stick weld them too but tig is definitely stronger...
Good luck

Re: Custom made crash cage?
Currently I'm looking for what kind of calipers I should use for my rear. I gonna fab me up a double or triple rear caliper braket.
good luck. Let me know how it goes... Thread Starter

Re: Custom made crash cage?
I'm doing the same thing you are looking around at all the different subframes and taking certain details from all to pretty much make a hybrid of my own. Honestly you can make that subcage to whatever size you want (your a fabricator!) But if ur asking what size...mmm I think it's 1/2" to 1" pegs..
