The 140 legs are a bit bigger so the scope should a bit steadier.

Yes and 140 legs dont slide down like orginal legs do, tighting system is not good on them, and they broke too easy.

My 80mm f15 Jaegers is on a 114 mount that has 140 legs. Seems like a good combination (the OTA is actually quite light). Very portable, but also quite stable. 

 

At first, I was a bit put off by the fixed height of the Unitron legs on the first 114 that I got, but then I realized that I generally use all my extensible leg tripods at the same height. There are a few situations, like outreach with smaller children, where it can be an issue, but the Unitron legs are quicker to get set. And as long as the ground will keep the tips from slipping, it can be adjusted for slopes by leaving off the spreader. 

 

Even so, I feel that I do need to build a spreader for it before it goes out on loan, in case it gets set up on a slippery floor.

This part, there is piece off metal inside and it falls off . Two small philipheads strips out off the wood.

The design is not good.  The nut in the wood is held in by the two metal brackets.  The nut should be on the inside.  Maybe you can just flip that part of the leg so it is.

 

Also, some similar tripods have a L-shaped piece of metal that the bolt tightens onto to keep from damaging the center section of wood.

Those old tripods have driven me nuts.  It seems no matter what I did, tightening the bolts, adding in shims, never seemed to help the little vibrations.

On a couple of tripods, I have eliminated those metal brackets.  Even with the bolts as tight as they can be, the tripod still twists a bit.  They eyepiece trays that are attached with those cotter pins do not help.

So I just eliminated all the hardware and bolted the legs together.  It's really not much harder to break it all down to put it back in it's box.

I also added in a chain for the legs that has a turn buckle to tighten everything up too. (turnbuckle is not seen in the photo)

He's in rehab.  A guy would have to drink a lot to get a whisky named after him.
