This weekend I was working on my Lab style Espresso machine ( post coming this week ) and on the Top Speed Bicycle.
Good weekend of just hammering in the shop on all the projects and keeping the young kids happy teaching welding, by the way I had my youngest TIG student this weekend, 8 years old and I was proud to see him running the torch. Its amazing what kids can do if you get the wheels turning on proper methods and safety!
Friday I picked up the huge block, all 26 pounds of 7075 aluminum to make the front hub for the Top Speed bike. If you look at the 3D model you can see the front steering is inside the hub so it requires the hub to cup over the front steering point on the bike. Its not a big deal except for the fact that I need to start out with a huge 4 3/4 inch round of 7075 aluminum. This grade of aluminum is an amazing grade to machine and makes very light parts out of, but your welding fact for the day is DO NOT weld it, and there is a link why if you have some time to read about welding.
Yep, I used a can of Murry's for a size reference!!
After I am done making the hub I will have a good chunk left of this bar left and the hub will be under a pound with a huge pile of chips left in the lathe, which to me might as well be my paycheck laying in the machine.

I love my shop, its coming together very nicely
Thats Margaret Holland's Oil Painting of " Chuck " on the right
Chuck is a living legend in the Santa Cruz, CA area I've heard
She is a really good oil painter and I get to hang it in my shop as inspiration !!!
And on the left is Louise Chen's " Love to Bee Home" painting
Oh Yeah, the bike is coming along as well, got some 4130 tubes tacked on after 9 hours of making about 15 mistakes trying to put tight bend after tight bend on to rolled tubing ( kids don't do this at home, its not a good idea if you only have one shot to get it right )
Good People
