Spent the day on domestic chores that where over due, but did manage to sneak in a tiny ammout of shop time cleaning the lathe and mounting a new (free) Starrett wall chart. The large Fisher-Price size numbers are easy on the eyes and the frame was already in the mix. Starrett will send out wall charts and pocket charts free if you register online with them. Another member shared this earlier in the week and sure enough it arrived. The yard work took up most of the day but the Hell Hounds (aka babies) sure appreciated the effort. http://www.starrett.com/documentation

Well this is not really a project of the day, since it has been a couple of months in the making. And came together today.
My 14 year old grand daughter asked me if I could help her with a science fair project that would be due in April 08, 2016.."Why sure, what is it?". I want to make a demonstration of how a canal river lock works. One of the historic Canadian Rideau river canal locks.... Sure that is fine..."with water". omg. How can one resist.
So for the past number of weeks I have been mentoring her on the use of my shop equipment. I made the original plans since I knew the travel limitations of my bandsaw, mill and lathe, so scaled the lock accordingly.
Since it had to be water tight we decided to make it out of acrylic, and put everything together with welding solvent.
The project involved machining of acrylic, brass, aluminum and steel. She learned to be comfortable with the lathe, mill, small rotary tool grinder, and a number of hand tools, including taping and cutting external threads with dies.
Today we finished off the lock push rod crabs. When I told her that we needed to drill a hole in each crab for the tension pin...she said ok.. put them one at a time (there are 4 of them) in the mill vise, used the centre drill, then followed up with the final bit without my supervision.
Although the final outcome is what she has been waiting for, for me it was the journey. She has been like a sponge, totally involved and wanting more.
The model working lock is about 22" wide and 10" overall high. Here are a couple of pics;

Depends on thickness of metal. On 1/8" metal I use 1/16 filler and 1/16" tungsten. Anything 3/32" or thicker I've been using 3/32" Tungsten and filler. So far on DC that has worked great.

I'll have to check at HD and Lowes then for some springs again.
I was wondering about the cup for the ram.
I guess I can add that to it, but hate to mess up my Blue paint job.

Not really a major project but...One of the Electrical/Instrumentation Engineers found a bolt in his office. He went 'yammering' on 
about how they only used small screws and bolts and why was this in his office. So, when he was distracted I pocketed the item in question. 
Not precise machining, all lathe work done in a couple of hours but...we'll see what he says when he finds it on his desk tomorrow.

Is this the equivalent of a hole in one or robyn Hooding an arrow ?
I had to drill out a scope mount screw opposite the head to get the mount off.
Not my taste in guns but fun to work on.
