Making a Rotary Table

<< < (20/20)

vtsteam:
Agreed. It's the Gingery influence.  :)

NormanV:
Did the basic machining on the castings for the tailstock today.

NormanV:
The tailstock is more or less finished, all I need to do is to knurl the knob (or other gripping system) and make a lever to replace the clamping nut. It is not a thing of beauty but it works. I milled a slot for a locating screw to prevent the centre ram from rotating and incorporated a proper clamping device to lock the ram. I had intended having slots in the base for clamping screws but decided I would use loose clamps which would give me more latitude in positioning it.
The vertical slot in the centre is for a jacking screw to facilitate adjustment of the height.

NormanV:
Two and a half years after completing this rotary table I have finally got a need for it but before using it. I decided to do away with the grid of holes in the top, that would fill with swarf the first time that I used it, and to cut tee slots. I have had the cutter for over a year but was worried about spoiling the table. I needn't have worried it was very straightforward to do and now I have it set up to cut the slots for the spokes in a rear wheel hub for a "Minnie" traction engine(cast aluminium of course!). First though I need to make the milling cutter for the slots as I do not have one of the correct size.
