Yep...this is the guilty one.
This summer a fellow astronomer from our local forum donated me an old, pretty fragile aluminum tripod from an EQ 1 mount or something.
So finally after a couple of weeks with a rocky health I started to tune this baby up a little. Decided to change the hole base which is ridiculous tiny. So I went to my country house the last weekend and turned on my home made lathe some plywood disks which will be glued togather with epoxy to form a solid ~5" base.

The plywood base is made of 4 sheets 7mm thick. The idea would be to cut the last one to insert the 1" aluminum brakets which will connect the legs of the tripod.
So I've started to drill 1" holes first and tommorow I'll finish to cut the hole thing. Then epoxy  ...lots and lots of epoxy.
In the end I'll bind all three legs by aluminum tubing to make the tripod as stiff as possible.

Hey, I've got a tripod like that from a 4.5" reflector I rescued. OTA is on a GOTO mount now, so the tripod has been sitting there unused, because it's... well, as you said neo - old and fragile.
I'll be watching your progress with much interest.

Thanks guys!
Well...a little update..
Today I've finished cutting the plywood disk and I've cut the three brakets which will hold the legs. This brakets are simply 1" aluminum tubing which will be glued and tied up with screws to the plywood base.

The base with the 3 brakets in place.
I've drilled the holes for legs screws. In order not to wear out the thinn aluminum brackets because of the screws I plan to epoxy some 8mmOD x 6mmID round tubing on each of them. So the legs screws will hold on a much larger area.
Tommorow I'll finally glue the base togather and I'll drill the rest of the holes.

A small scope that gets used often is a better investment than a big scope that stays in the closet.
Unitrons, you spend more time looking at them than you do through them.

I'm liking where this is going.
What scope(s) are you planning on using with it, neo?

This is nice, but because the entire scope weight is bearing on the interface of aluminum to wood, I think I would secure the leg bosses from below with machine screws - drill through the wood and aluminum then tap out to the needed size - cap off with a hex nut epoxied in place. Nice wood work!

Thnks again guys! You're to kind. I had no idea that a humble tripod would be so popular 
- drl...of course I have that allready in plan for today. I'll secure with two screws and epoxy each bosse...bracket...whatever ..thanks for observation.
Well...the tripod is mainly for my 70mm Rodenstok lens refractor which I'm currently trying to rebuild. But I believe that after all the tweaks are done I can load it with much bigger scopes in the future.
I still have to buy some more supplies for this project including a new set of thumbscrews and a nice blue bag from Telescope House

you could of course replicate the wood you already have and sandwich the aluminium sections between two lots of wood.

I've thought of that too. But first of all I wanted a thick solid base, second, I wanted to keep the legs ends a bit beneath it to get more clearance for the rest of the mount. The problem is that the aluminum tubing is 1" thick and the plywood is 0.27" so in order to build a full base with that sandwich configuration it gets bit more complicated. I like to keep it simpe for this project  .
Ok boys...I'm out to buy some epoxy...

All righty then ! 
Some progress today...
I've finished to drill all the holes (to many ) and to cut the small tubes which will hold the legs screws.
Then, epoxy time...
Today, while I went down to the local hardware store I jast got the idea of using some 1" table legs covers for the brackets. The result is quite nice, I believe.

Finally the big moment...glueing the base.
Tommorow will be the moment of truth .

neo..I hope your wearing a respirator or have lots of air movement while using epoxy, in some people , exposure leads to allergic reaction to the slighttest whif of it, Im in that boat from building rockets indoors in the winter.Just a heads up.
Very nice Job though,
