What I'm actually more worried about is the weight of the top (I'll be
doing
this solo). With the wing removed I believe I can manage it. Any idea
what the
weight of the top is?

About 250 or less...I don't recall exact dimensions but they're roughly
27" deep by 40" including wing iirc. Presuming extension is 10" that's
27x30 and if assume 1" thick on average that's just a little over 200
lb. or so.

I think you are way over estimating, the motor and trunion will be a
majority of the weight and the top is not solid, typically it is about
1/4" thick.

A) Intended.

B) Is solid, but webbed.


Yeah, what I meant to indicate was not solid 1" thick.


Actually to be anal about it, using an iron weight calculator, a 1/4"
thick by 27 x 40 would weigh about 70lbs. Add 50% more for the webbing
and you are at about 105 lbs.


27 x 40 would be the dimension of the top w/both wings attached. I would've
thought that would be closer to 200lbs or more.

I Checked the thickness of my top. Took a 6" C-clamp, screw side underneath, and
snugged it up on a flat area (not on webbing). Wrapped a piece of tape around
where the clamp's male threads entered the female thread clamp portion. Removed
clamp, screwed the thing until the the tape just hit the female portion and
measured the distance between the swivel pad and the stationary thingy and got a
distance of 3/8"!

The top by itself (no wings attached) measures 27 x 20, it's 3/8 thick, the edge
is 1 5/8 wide, the edge and webbing are roughly 5/16 thick.

I'm curious to know what the weight is if you plugged those figures in your
'cast iron calculator'
