Has anyone made the College engineering supplies 6" rotary table ?

I understand these castings are no longer available, but I have a set and would like to get started on it,

Any problems ? how did you get on with it ?

Richard.

You are lucky, I have wanted to build one for years, such a shame CES don't sell castings anymore.

FYI Harold Hall describes how to make it in MEW 101/102

There does not look to be anything special about the castings that could not be cut from a block and 2 discs of cast iron bar

Hi Alain,

I built mine around 1988 and think that the only problem would be making the worm and wheel. I got round this by buying them ready made 8^)

My workshop has been in limbo for about 12 years but now I am picking up the pieces again. I cannot immediately find the drawings for the table.

A question to you or others on the thread - what is the collar and lever rod on the drive shaft ? I am guessing it is a lock for the table. It is immovable on my version. Stored out of doors in cling film for a year or so probably a bit rusty although overall the unit is black and greasy.

Regards, elegy

Pure guesswork on my behalf, but it looks as if it controls the mesh of the worm with the wheel.

(Based on what a similar lever does on a Vertex HV6 - hence guesswork )

If someone has the original drawings and instructions, they could confirm or refute this proposition.

WD40 or some form of penetrating oil might help free it off, if only gradually, with lots of wiggling to and fro.

Yes it is for controlling the mesh of the worm. I have the drawings and can post them if anyone is interested.
