Looks GREAT to me. Half pound 8 oz. I like 13 oz. Make a video of it in action please, and how about a video on the lathe you are making it on?

Well finished it to a playable point.  The original plan was to make it a one way bearing top, but I kept messing up the bearing seat.  I've thought about how to fix it and eventually plan on doing that if I can.  For now I just threw together a fixed tip to slap on it and to see how it plays.  It's super fun, but extremely different.  The largest top I've played with before this was 3", so this thing feels massive!  Here's a video of me attempting to use it, might have gone better if I decided which tricks to do before I started throwing.  Ended up being 300 grams (10 1/2ish oz) with the fixed tip, that's a number I can live with!

Oh, just for fun I decided to see how many short circuits I could fit inside.  Sadly it was just two  ;D

Fantastic!  8)

Only 300 gr for a 5" delrin top? You must have carved it really well.

I was pretty nervous hollowing it out.  Took a lot of time and light passes when I got close to my target width to try to keep things from getting too thin.  The walls ended up being just shy of 4mm thick (I was shooting for 0.15"), though I did add a hair of width at the widest part (just over 1 mm).  It feels pretty solid, but we'll see how durable this thing ends up being in the long run.

I think you did a FANTASTIC JOB. I like straight tips only. I want the stairway to heaven and the wire walkers. My self I would have made the wall 1/4 inch to be safe. Take that honey to the park use long line and let HER fly. JUST BEAUTIFUL.

Thanks! 1/4" would have been way too heavy for me, I figured try making it thinner than there's not too much money down the drain as the blank was pretty cheap, but it does feel pretty solid.  We'll see what happens.
I took my camera out to take video of finishing the top up, but I set it down and completely forgot!  I'm just using the Harbor Freight Benchtop Lathe.  Most of my hollowing is done with a homemade hollowing tool made from an old screwdriver (originally was going to put a carbide insert on it, but after failing because of how hard the steel was I decided just to turn it into a hollowing tool).  The tailstock has a bit of lateral play, which is part of the reason I don't think I've been able to get a perfectly smooth top yet (though there could be more factors at play).  It's a nice and cheap little lathe, but I'm thinking about upgrading at some point...

Yep!  Tip is also delrin.  I put a metal machine screw through the tip to reinforce it, this extends through the back of the tip and there's a nut on the inside of the top holding the tip in and in place.
