I originally was going to retire 6 years ago and now 6 years later still a little not sure I'm ready mentally. I figure if I'm not ready and want to go back working I'll be able to find something. We shall see.
  Anyway just about to go to a retirement party for one of my friends his last day was today. Go have a couple ales and unwind.
Not gong to get to the shop until tomorrow afternoon.

OK wasn't at the party long and did get out in the shop and worked on the legs. It's seems a little top heavy right now I'll see after I get the flywheel made and put in place along with power cylinder and see how it feels the. If it still feels a little tipy and top heavy I'll add a couple cross beam under it to widen its stance. So here is what I've got so far.

What are the white legs made from Doc. I assume a plastic of some sort, but machined or 3D printed?

Doc, I know 43 years is a long time and retirement will be a huge change, but you have nothing to fear. You are active and have many interests. It's folk who suddenly stop work and then sit in front of the tv / read the paper all day that need to worry. I stopped when I was about 67 and now do three short days per week looking after the boss's collection of "old stuff". It's wonderful :whoohoo:   Get retired and enjoy yourself.

Very Best Wishes.....................Terry

Thanks Terry!

  They are made from 1/2 thick Corian. I really like how that stuff machines! I cut the windows in them then buzzed around the perimeter on my NC mill at full depth of cut with a little air to blow the chips away. Looked like a snow storm hit my machine afterwards  :ROFL:.

Yeah I bet though I have only one experience with it so far. I understand you shouldn't breath it in any more than absolutely necessary though. The kegs look great though.

Rather than blowing away the dust, a vacuum cleaner set up near the cutting too would perhaps be better.
You might find that you will have to screw the legs on to a base board of some sort, even if that doesn't fall over, it will probably go walkies.

  Thanks Ian !
    I was thinking along that line I am thinking a piece  of corian for a base under the whole thing. Yes I do use a vacuum a lot on the mill trouble is doesn't seem to work very well on small end mills to get the chips out of the way. I need to come up with a smallish nozzle for the vacuum to get it where it will pull the chips a way. The nice thing it really wasn't much dust mostly chips that were along the line of feathers. May have had the feed-rate a little to slow I wasn't sure of the sfpm so I used aluminum feed rate and just increased it a little. I'm not up on feeds and speeds for plastics.

Was really nice outside this afternoon ended up taking Rowdy "my boxer" for a long walk so didn't get a whole lot done this afternoon king of like this morning. But I did get the bearing mount blocks "pillow blocks". So I am making headway on it just not to fast.

Hmmm guess I didn't realize that couldn't load it here it is just over 4mb and one file here cannot be over 1mb. I probably should remove it then.

Congrats on retirement Doc.
Sorry you were/got sick.
If it helps any...the 2nd to the last day of my work...I was passing a gallstone. Luckily that was a Thursday and we were off on Friday.
Had the weekend to recover before I retired on Monday.

(I don't have a gall bladder...but I have a stricture in a bile duct that, once in a while, gets plugged. Think the Alien movie.)

So keep at it! Enjoy! Most people don't have a hobby or anything to do. You have a shop. Enjoy!
