Next 1/16th machine; Universal Miller

Can anyone guess what it is?



I cant be just laying bricks, so i started on the next machine.
Those paying attention can likely guess, and it is based on a CHB kit.

Looks like a serum injector, used by Dr. McCoy, in the original Star Trek series.

Did I guess correctly!?

Horizontal milling machine?

What is the blue material?

Hello Marty,

how each model of you certainly great.
I'm looking forward to the continuation of you.

Good Job! Paul & Chuck!

I have not found too many images on the 'net or any very useful information.

The main/blue part is some sort of acrylic Mr. potato Head sent me.

Marty,

I have a book that might be useful, let me take a look and see whats in there, I can post some scans.

OK I checked my book and its not as good as I thought for pics, lots of text about dividing and such.

Try this link, scroll down to the B&S stuff, lots of other info too.

You've got a bunch of work to do before Marc's guess stops looking like the right answer! 

Looking forward to more miniature machinery madness!  -- Dallas

I'm still working on my serum injector...er...um...Milling machine!

That link is excellent! Thank you!

I have a question; May be you or Russ (NEBrownstone) can answer?
On the back of the machine there is a guard,
runs from the driven pulley shaft to an idler then to the gearbox or "variable feed mechanism"
In Charlies 1:48 model he calls it a "chain guard"
It looks more like a belt cover than chain.
And a chain seems very unlikely to me.
Any thoughts or knowledge?

Thanks!

Hi Marty,

Do you have a picture by chance?

From what you are describing it IS a chain guard.  My old mill had a "silent chain" kind of like the old timing chains on engines that was hidden under a cast iron guard.  It transfers power from the spindle shaft to the gearbox that drives the table.  There is a shaft that connects the gearbox to the table through a couple of universal joints.  All of this had to be "timed" when using a universal power dividing head when milling spirals (twist drills and spiral mills) so that the path would remain the same, with only the tool depth being changed for another attack on the material.  You could change the speed of the table and the dividing head gearing to produce helix paths of varying degrees depending upon the requirements.  Simple indexing didn't require this timing and most of the time the gearbox was simply for table feed speed. 

Some of the earlier mills used small belts to power the feed, but that went out of favor since belts have a tendency to slip.

Hope that answered your question.

Hope that answered your question.

PERFECTLY!
Thanks!

Now how to model that "silent chain"...............

Put cover over it and pretend it is in there.
