Hinge Design ?

[Lbob131]

Our LARGE Neat Elite Hinges now have built-in lubrication points.  This is an innovative design and no other hinge design has this as a feature.

Can anyone  explain  how  that  is achieved?
Also...
solid brass and have a fully balanced built in stop which locates at 92 degrees

What  machine  do I need  to make  this  hinge?  Any pointers?
I get  the feeling it is  cnc.
Many thanks.

As one would expect from a (parent) company like Hawthorne Fine Boxes Ltd., Fine Box Hardware is running, per their own account, a machine from Haas.

Thanks  so much.
Looks like  a  mine  field. [unsure]

I've  had  time  now  to search  all through  the Haas  website  and  they  just  seem  to make  high end  factory  machines.
However  I came  acrosshttps://www.prototools.co.uk/  here  in  the UK  and  their  High Z  machines  certainly  seem  to be on a par  with  the  one  in  the  Hawthrone  video.

The  one  big difference  I notice is  the  y axis  motors  are  mounted  on  the  X  beam.

A small mill/drill machine and a rotary table could machine that hinge. 
You might have to get a little inventive on how to retain the hinge pin.
But if you are asking how to make it, you don't have the skills/tooling/measuring instruments to machine it accurately.

It's purely about volume at this point. Any competent manual machinist could make such a thing, but I guarantee you that you are ready for the price of doing it that way.
CNC offers speed and minimal human interface, other than creating the model in the first place. Once that is done, an operator can run these all day long.

Thats  quite a  statement. I almost  find  it offensive. [blink]
I  may  not  have  cnc  but  I made  this  with  the  tools  in my  work shop....
An  exact  copy  of  an  English  Saxony spinning wheel  made  from a  slab  of  mahogony  that I chopped  up..
That  sat in that  exact  corner  topping a  cabinet.

The Haas CNC stuff are all very nice machine tools but there is a serious commitment that goes along with the purchase.

The smallest machine they offer is the TM-0 which costs $32,995, weighs 3660 lbs, uses 220V @ 40A or 440V 3-phase @ 25A and needs a compressed air supply of 4 scfm @ 100 psi.

If the standard 4000 rpm spindle is too slow (most likely) then you'll need to pop for the 6000 rpm spindle at $3895 or the 10,000 rpm spindle at $4995.

Add in the tooling, accessories that are needed and the facilitization and this soon becomes a $50,000+ endeavor.

These hinges could be made on a conventional mill/drill tool but it will be slow going.

You might also consider the Shaper Origin to machine the basic hinge leg profiles along with the attachment holes however the
hinge pin area will need some special fixturing and possibly tooling.

This is all possible as long as you stay with brass as the material, if you want stainless instead, then all bets are off and the Haas will be your friend.  [smile]

That spinning wheel is beautiful!

May I kindly ask what the goal is in regard to these hinges?

Do you want to make a pair for yourself to use on a box project? And there is the "sole authorship"/ I made all of it aspect to it?

Do you want to make a pair to prove to yourself you can do it? Is it the reverse engineering aspect?

Because looking at the price of these from Fine Box Hardware, Brass is 47 Pound (large) or 27 Pound (small), and Stainless would be 65 Pound or 47 Pound, I really don't see any economic advantage when you need to start from scratch and probably need to invest in at least some form of tool(ing).

So maybe just tell us what it is about, to better understand the situation? ( I've done a lot of crazy things, so I totally get the "sole authorship" thing for example, if that is what it is.)

Kind regards,
Oliver

If you had to you could make it with a drill press, an end mill bit, a drill bit, and counter sink bit. Then a polishing setup. But starting with a proper milling machine would be better and safer.

I mistakenly  thought  the  wood  cnc  in the video  was the  Haas. [embarassed]
I had  seen  utube  videos  of  people  machining  brass  with  their  standard  cnc  router  set  ups.
Heck.. I've machined  brass  on my  wood  lathe.

The  hinges  are  for a  set  of  small  boxes  my nephew  is making. I have  seen  cheaper  ones  else  where.
Im not  sure  I'd  want  to delve  into  any  form  of  cnc  as  my  main  line  of  work  does  not require  it.

The other things to consider if making more than a single pair, is the need for a number of jigs to handle the multiple machining processes required. Then of course after all that, polishing to remove all the machining marks will be fairly intensive.

Machining brass on a small CNC isn't an issue, it's actually quite easy to machine, but it does also work harden which can be a problem.

I have worked brass with the Shaper Origin. I opted to use the Orign to create a patern in the brass then cut with a band saw and sanded/polished. The reason was the brass shards, they're very sharp and get everywhere.

The hoop for these door knockers are what I patterned with the Origin, all the rest was lathe work.

I mentioned in the Working with Aluminium thread I may be making some door knobs. Paint can for scale.

Man I'd love to see the door THOSE knobs are going on!

Nice work Tom!

Beautiful work Tom! They look great, and I love the colour of the doors!
