Maybe I'm getting old and lazy or maybe it's old and wise! LOL

Was in RONA last night getting some "all tube" compression fittings and with
all the advise stuck in my mind about sticking with the small MAM pump out
cups.... while there grabbed an ABS male sweat 1-1/2" to 3/4NPT bushing and
a 3/4 NPT x 3/4 hose barb. This made a perfect adapter for the standard
Beckson float cup pump with a piece of 3/4id x 1" od hose on it. The Beckson
pumps rubber seal fits tightly inside the bushing and doesn't fall off
allowing your to use the pump for either size cup. I already had 4 brand new
Beckson pumps here so wasn't buying another one.

I also picked up my new (Howard's old) air lift for the plane on Tuesday
morning.

Basically 4" x 4" alum angle welded together. Built in two sections that
bolt together in the middle so it can be transported and carried. Two
Stainless steel 2' x 2' x 4' air tanks that bolt under the frame on the
outboard end. Wood deck the shape of the float bottoms to sit on. When you
look at the pics you will see a large tube welded to the bottom of the tank.
This is a hole into the tank bottom. Air pumped in forces water out and it
lifts the airplane out of the water and will stay there for months. The tube
stops any leakage from the unit rocking in the water. When you want to go
flying just open the dump valve and the water replaces the air...thus
sinking the unit and the airplane will float off.

I have posted pictures of both to the Rebel - Float installation section in
the archives.

Since the aircraft looks to be tied down to the lift it might be
desireable to have some residual water in the lifting tanks to provide
some weight during a windstorm. Ahh but you guys are probably clever
enough to just not blow out all the water or to lower it a bit during a
storm. ;)

I'd estimate the lifts weight at about 600lbs...plus it's attached to the
shore...although in Howard's case that was just some 2 x 4 pieces lagged
into the rock shore to form a hinge block for the front angles.

Didn't blow away in 7 seasons on the water and he was pretty vulnerable to
North/South and Eastward winds. Don't remember him ever saying he sunk
it...but he could very well have and a great idea Ken for when not attended.
Partial submersion!

Thanks....at least I know someone's ready my posts!,

Wayne. I personally read your posts every night. The wealth of information
and replying occasionally to duplicate requests refreshes my tiring mine. I
am sure there are many others who also do the same. I would just like to
know how you find the time to answer so many requests. After next week I
will join the group of semi-retired and may be able to contribute a bit more
myself. There has been many requests I would have liked to answered, but
have been just to SHORT on time.(as well as height). Now I can get to some
serious Rebel building. Bob J Formerly Rebel "652" currently assisting on
Rebel "725"

Thanks....at least I know someone's ready my posts!,

Thanks Bob! My posts are probably going to come to an end very shortly. As
most of you already know, I sold my share of the plastics business end of
Feb.... so I can spend more quality time with my honey while she is still
able. Not going to wait until it's too late. I've still got a full plate
here before I can really go up North (CYP still not back from paint #$*&#*#!
and still have my float install to do), but once I do get North the posts
will end until late fall probably. I have no intentions at this point to get
internet access up there.

Cheers,
Wayne
