Nice. How are you sealing the edges? Looks like some sort of o-ring material.

Yeah I'm just using rubber oring, kinda stiff stuff, proper material is a foam rubber gasket cord, much softer but I can't think of the name right now
 
What I did in my shop today: I had brain farts.

I was making a couple of boring bars to use in my boring head. I needed to cut a 1/8" slot in the end of one about 3/4" deep. I was wondering how to best go about this without breaking the end mill. I was standing in front of the machine thinking about this. Right next to the machine stands a plywood board with a bunch of nails in in it. On each nail was at least one slitting saw or horizontal mill cutter. What makes it even better is the fact that I made an arbor for my mill drill last week so I could use them.

Later on I needed to mill another bar at 60° so I was trying to figure out how to hold my 30° angle block along with a 25° and a 5° block to get 60°. Then I remembered and rotated the 30° block to the 60° position.

So I'm not feeling too smart today.

The trained monkeys who built my Vertex rotary table didn't quite finish the casting, which is surprising because the rest of the fit and finish is great. The bolt holes in the base still has casting flash and were never finished so a 1/2 inch hold down bolt would not go in.

Maybe they were M12 holes…

Just to show curious minds what I was actually cutting out on the vac chuck, I've been working on a knife blade design, once I'm happy with the blade design I will design the handle (titanium) around it. This is the second revision of the design, it features a machined bevel to the edge which is obviously not shown, but I have proven the machining of it in simulation....

Shaper use.
My day off!!
A friend of mine called wanting to chat while he was driving home from work.
I mentioned that I had to go check on my shaper.
He asked "shaper?". You seem to use that alot.
Truth is- yes. She gives as good or better finish than the mill. Yes, she is slow. But, she enables me to multi task.
I can set up a relatively inexpensive HSS in the tool holder and let her go. If she overcuts by an inch no harm done.
Can't do that with a mill which needs expensive cutters.

Meanwhile I can be at the drafting board, sometimes the lathe, and certainly on the phone.
I.m not clear on why they aren't more common.

Hey Daryl, I bought an Acme 7" shaper back in March, but have never set it up yet. Need to make a stand for it and it's just been too hot down here in S. Texas to do any welding and fabricating. Also had colonoscopy done today, which turned out ok, thank the Lord.
Anyway hope to get started on it in the next couple of weeks. It was working fine when I bought it, got to run it for a while. Has all the original parts, including vise and tool holders. I do see where they would come in handy sometimes.

The cutters are ground a little different than lathe cutters.
She fun, simple and effective.
You.ll have fun with her!
