Re: Getting closer to having a hood
I hit a curb once, out in LA, while going sideways at a pretty good clip. Caught it a pretty good lick with the back tire. Tore the tire and broke the center out of the wheel. Bent the axle too. Don't remember it tipping though. But I was only a few inches off my line so I can see where if you got really crossed up it could be different. I've tipped cars up a couple times, doing it in the MGB would be an accomplishment. Doing it with Jim's wide MGB would undoubtedly involve a considerably high rate of speed and something more significant than a curb.

Re: Getting closer to having a hood
Right, we're buying that!
RE: oval... I've seen folks do two round and then basically wrap them in thin sheet metal. Was thinking a wider one like that would look good on your car. |

Re: Getting closer to having a hood
Not sure I agree about not flipping it against a curb. Obviously it would take quite a bit of speed, but I'm guessing it won't take long to get to warp speed in that machine.
I'm thinking it may look better & sleeker without a roll bar. |

Re: Getting closer to having a hood
I had considered filling in the holes in the sheetmetal ahead of the trunk and not running a rollbar - I agree it would look better and sleeker without. I do want to run it at a Goodguys slalom event and they require roll bars on open cars and possibly run a track day sometime. I think that making the top section slightly curved to match the curve of the windshield frame will make it blend in to the design of the car better. At any rate, it will give me an attachment point for the seat belts.

Re: Getting closer to having a hood
Seat belt attachment calls for a second horizontal bar at approximately shoulder height.
Together with a little bracing, you can achieve a lot of side-impact protection. |

Re: Getting closer to having a hood
I will have a horizontal bar if I ever decide to use shoulder harnesses but for now the upper mount of a 3 point will mount to the vertical section of the hoop.

Re: Getting closer to having a hood
Got the skin crimped onto the frame so it's a nice rigid structure now. I added a center support to help keep the insulation in place. The weight of the completed hood is 33 lbs. I've never weighed one but I understand that a stock MGB steel hood weighs 30 lbs so it isn't too terribly heavy.
Now I have to work on getting it adjusted to fit well. Edited 1 time(s). Last edit at 07/14/2015 03:55PM by Jim Stabe. |

Re: Getting closer to having a hood
Fiddled around with it for a couple hours and have it fitting pretty well. The drivers side gap is pretty nice and I can close the other side up by moving the fender The gap at the back is wide in the center of the car because I didn't know how to bend a curved flange in sheetmetal when I made the filler piece for the cowl. It will be fixed before paint. I had to reshape the curvature over the grille with a little judicious hammer and wood block work but it fits pretty well now and the latch works.

Re: Getting closer to having a hood
It needs to be a particular shape, an exact width and I also want it out of 2" tubing to make it look right. I had another one made but it didn't look right because the bends were too tight. It's not a big deal, I just have to get the tubing bent up and weld on the plates.
