Beadbreaker Design

Hello All,
Here is my newly crafted beadbreaker.

Shows side view, where you can see the grappling hook (notch is for hooking onto "spokes" of 120 GX steelies) and the push foot partially engaged.


Here it is again, on a 13" trailer tyre.


So what's my verdict?
Advantages are:
- Breaks stubborn beads easily. It has a 200mm stroke, so once the tool is set (grappling hook has squeezed the tool feet behind the rim), the push foot WILL push the bead off.
- Smaller form factor than R&R Beadbreaker & Tyrepliers.
- Works very quickly - can set the tool with a spanner in about 15 seconds, then break the bead in another 15.

Disadvantages are:
- Bigger, heavier, and more complicated than AJ120's simple beak breaker (which is ideal for all but the most stubborn beads anyway).

Nice work mate. I have always just used my highlift jack to break beads.

Thanks for the nice comment, much appreciated.

Yep, I like the idea of a "jack powered" bead breaker because its simple and always on/in the car.

On this occasion, I went with this design I saw some youtube videos for a similar design that made it look kinda cool to use. That, and because my spare tyre was stuck on so well, the jack method didn't work.

Anyway, I reckon the hi-lift or "OEM jack-with-spade bit" methods will work for most people.
