CB 750

I have been designing my next bike using Solidworks.  I have done a few test designs on girder front ends. I tested 2 designs to see the strength comparison to the two.

I like this design the most each leg should weigh about 9.8lbs.  The simulation is short but it shows a static load of 550 lbs pushed to the ultimate point.  With a safety factor of 1.98 calculated this should withstand 1000lbs+.

This is a tried and true design that you see most often on a girder style front end.  With the same load this safety factor was only 1.57, and will hold about 870lbs.

The Idea is to cut this out of 3/8 solid plate.  Either using my CNC plasma, or just cut the shape out with the plasma, and then do the insides by hand....

I drew this up to simulate 1" DOM with .120 wall.  Simple but it gave me a great idea of what the other design will hold.

This is what I have so far. I posted another mock up a while bike.  You may notice the bike is shorter in the rear, more rake in the front, and obviously the new front end and some color scheme that I think I will go with.  I just need to do handle bars.

Elegance in machinery

I really think that moving machinery is so beautiful.  I love this table.  Some times I wish I was creative, or something.

This is your mind on KZ

A friend of mine put DJB in contact with me so we could fix up is boring old KZ1000

First thing that has to go is all that junk in the trunk!

Here's a tip use 1" conduit to mock up your next build 10' for $2 = way cheap!  I had this pic with the top rails being tacked up on the out side of the motor mount rails.  

Your next tip is Pick a better frame to chop...  Not that this won't turn out looking SWEET, but that it is all sorts of weird Japanese fabrication that I have to deal with to get good looking lines.

I borrowed the same seat DJB wants to use from Brandy Knotts, and I think it Looks SICK!

Tip 3, when you need to make a slot in your stuff always drill a hole at the end of the slot to make that drop piece come out nice and easy, and it looks totally cleaner.  Luv the port-a-band

And here you have it all chopped, cut, bent, and tacked together. Not bad for just one days work on the bike actually doing some work on it.  Only had to cut one piece over, so I used about 12' of 1"x.120 tube.
