Dang it, Rob, you're making me feel like a slacker again.

I hung a couple of florescent light fixtures in the garage so I can see better when I weld. Unfortunately I only had enough bulbs to populate one fixture. I thought I had enough but was wrong, again.

a job well dun rob

Ed, I put in ONE of those cf twisty bulbs in my shop. It draws about the same as a standard 2 bulb florescent but delivers more than 4 times the light. When that thing's on it's daytime in here. My neighbor has two of the same ones in his shop (wood shop) and when he has both on, from outside it looks like a nuclear event just took place in there.

I finally got around to doing a bit of machining on the AR15 forgings I had acquired. Got the outside contour milled and the numerous holes and slots cut for the safety, mag release and hammer pivot, etc. It's been a while since I've machined any 7075 and I must admit, the stuff is pretty impressive. Nice sharp end mills are a must.

Just finished knocking up a couple of ramps to use at work , 3 ft x 1 ft x 6"  made from a wee bit of 1/8 plate .

Good for 50 ton the pair

Rob,

Those are seriously nice ramps! How much do they weigh?

Will they be in a rather permanent location? If not, would they need handles or slots to aid in having a lift point?

[dallen]

what size did you end up with for the selector?

I love 7075. It's incredibly strong for aluminum, machines a little tougher than 6061-T651 but the tensile strength and dimensional stability is superior. A place not far from me that specializes in AR15 type guns and accessories uses that 7075 for anything where steel isn't absolutely required. And they make top-notch stuff.

I used a .376 reamer David. Don't know exactly what the fit is, but it feels pretty good.

Ken,
It's surprising how much effort it takes to push a drill through the stuff, but it sure leaves a nice finish.
