Thanks Crowie ! I didn't show the rear view, that is a surprise element for later.

Excellent Work as always Gus. I am really enjoying this. Look forward to the next post.

Recalled the number of initially unsuccessful elements of the last project, I decided to make the mechanisms without positioning the M & F characters in the beginning. They are leaning forward, so the head movement parts will be at an angle to the drive shaft/gears etc. I needed to see if I can make a workable uni joint to overcome that problem. Made using 15mm square jarrah, 60mm long overall and using steel pins for the pivots. Seems to work smoothly, now just have to figure out the rest.
Thanks for looking.

Looks Great Gus,

These will be painted possibly white. This is the last of the works before the mechanicals begin, hopefully will have some progress soon.

Coming along beautifully Gus

The waiter must have two quite long pauses, when arriving at the table, and in the kitchen. Other movement must happen during this period. The previous automata mechanism I used did not provide enough time, this clutch appears do that.
The output gear turns a shaft constantly. The lever which moves the rack and pinion is engaged when the cam followers are enabled by the fixed cam adjacent. There is some fine tuning to be done, but it appears to work as intended. I hope the very poor video will illustrate the action.
Thanks for watching.

I have already said it in my personal email to you Gus but

WOW, WOW, WOW, WOW - you are a genius mate. How did you think that out. What fantastic skills. I am in awe. Make my stuff look pretty mundane. You are indeed a very skilful person - FANTASTIC - can't wait to see how you connect to the dining setting you have made for the anniversary.

Involving three gears and a pinwheel, the speed reduction is 11:1, leaving ( I hope) plenty of time for movements between pauses each end.

Very clever engineering Gus.....might catch up if you're at the show on Friday early...cheers crowie

Most of this is crude prototype, but it does exactly what I was wanting. Fixed block on the frame turns it to the guests, cam under turns it to 180º against a stop pin, the linear engine moves it back to the kitchen, a cam under turns it to the start position.
Thanks for looking,

No luck, I will get advice and repost.
