Rat Table Two

After flipping it and determining where the holes are to be placed it is off to the paint room.



This is where the center table gets attached. It will stay stationary, yet be slightly above the large table that spins.





Here is the top and bottom view of the center table. I had to stack and glue 3/4 ply to get the height from the base to above the table. As well as, I put in some recessed screws so the table will remain centered and stationary.



This is the ram in the closed position (above) to lock the the table. The open position (below) the table will free wheel.



This is a view of the complete mechanism. I used a horizontal hold down ram and lengthened its ram and made some brackets out of Al and delron.





The bottom is complete. The wood slats on each side of the holes are brackets for the cage.



The table right side up on cleaned and painted tripod. This shows the cage in one hole slot and the lock mechanism.




This is it! Finished. Notice the scale it is too big for the hall. The rat, blindfolded , is set in the center and the nest (cage) is in one hole. They take the rat and replace him on the center and spin the table to a different position. Then they track how the rat navigates with minimal external information.

Rat Table

Table Bottom (on its edge)...


Table Top (also on edge and center not built)...


Tripod (needs cleaning and paint)...

This is a table that rotates so a Rat (that is blinfolded) is to be placed on center, and is to find its home. The table then is turned and the Rat starts out again. The Psyc dept is studing the navigation routes for Rats. I am about half way done with this project. I had to build the tool to cut a table this big. The Department dreams up these things. I just bring them into reality.

Back at it!

Life interrupts when I sit down.
In addition, it can be painful.
I guess if I feel pain,
then I must be alive.

Follow up!!

The aluminum edging in a previous post is now in place. I used the edging to make a cover for two displays in the Biology museum.





These guys were watching me very closely. I had the feeling they were pissed off at something.

Hand stand

I was asked to make a stand to hold a very large crystal for the annual rock sale. As I was holding the crystal, I said my hand would be perfect if it were larger. LODI! Eureka has too much credit for inspiration, So I made this hand after mine but scaled it up by 1 and 1/2.

New projects

Project one is to make another one of these.(top three photos). It is a platform for a doppler sounder submerged in the bay. The instrument is to detect sediment from dredging.

Project two is to build a couple of animal skeletons displays for the museum. The excreted Aluminum runners just arrived. This will be interesting.(bottom two photos)

Stakes

The Biology Department every year asks us to make up some stakes for the Arboretum on campus.
These stakes hold signs giving the proper name of the tree or plant. Usually they ask for 100 or so, but this time it was for 400.
So I had to cut bend and drill 400. I know them personally, and will miss each and every one as they go out and do their job.
I think most of previous ones are getting sold to the same company I purchase these from, cause they look the same, just my opinion.
