I would still triangulate it..cheap, easy insurance. A couple more cuts, four more welds...priceless. :laugh: Looks like a great project!


What I've decided to do is actually use some trianles made out of 1/4" steel plate. Tat way the triangulation can be MUCH smaller, still allowing the whole "empty" look.

Glad your going to triangulate, and using the 1/4 steel is definately a good idea. Your probably right about it being just fine without triangulation, but it just makes me feel beteer knowing your going to do it anyway! :P

suh-weet!!!

I like the design dude. That's gonna be a beautiful ride.


Haha, I work in an automotive manufacturing plant and they make us wear safety glasses even when we're walking across the plant on the cat-walk. 30 feet above the working floor... At home, I never touch them though. Gloves either. And I have the scars to prove it. :blink:

Looks good twowheeled -- I too think you should triangulate -- don't think it'll hurt looks too much, but then I realize I'm not sure of your plans here... It's not the weight so much as the fatigue issue of bottoming, hitting bumps, etc.

Slow to check in here again. Bud -- thanks for adding a pic there. That's the spirit! You know you can spit/drool on the grinding wheel to cool it down -- just squint a little as you get down there. :P

Ryan -- I do not have to tube-ordering and welding skills of twowheeledterror. I ordered this frame bracing kit from Kosman engineering, and had somebody weld them in place. It's an excellent kit, all precut. Used for the dragbike guys. Made a BIG difference along with the motor mount kit in stiffness of frame.

Bangshift,
If you have a weight hanging from the bottom of your garage's roof support, you take a chance of pulling it apart or just breaking the horozontal boards.

Most of the time one or two hundred pounds can be ok hanging from a bottom rafter, but if you use a comealong you jerk the load going up and down and this creates more stress.

You can put a couple of vertical boards under the horozontal board and this may keep it from flexing and breaking.

If you are going to try to do it right, you need to hang the weight from the top of the roof support. (This does not mean to screw in an I bolt.) With the weight hanging from a chain looped over the top of the roof truss the roof support is pulled tighter together instead of apart.

Be concerned about the load capability of your roof.
Here in the midwest where roofs are designed for a significant snow load, the roof supports hold up pretty well to this abuse. However poorly built and home built garages are often just waiting for a reason to fail.

I think you should grind off the center stand mounts. Keep the side stand and make yourself a paddock stand.

I've found that masking tape in good quantities treats me well. :D
