 |
|
WTB: Want to Buy a head assembly for small shaper.
This would be ever thing that mounts to the ram.
Something from an Amoco, Southbend, Brodhead-Garrett etc. size
machine would be ideal.
An operational (or easily re-buildable) and complete assembly is
required. Light surface rust ok.
Slide to ram angle scales are not particularly important as these
may be fastened to the ram.
I am also looking for advice and suggestions in addition to a
head assembly. Would anyone care to share their pet peeves
and/or desired features about a shaper head assembly or shaper
operation? For example, how would you feel about using a large
knurled knob with detents in place of the classic ball handle
with a small collar with hard to read scales? Instead of
adjusting 10 thou in by the scale, just go in 10 clicks.

George..you looking for the clapper box or the clapper box, compound
etc?
What length extension do you need and what size tooling will you be
running?

I want the whole skippy.
Actually as I considered the problem in more depth I could even
use the ram. Largest tool that I would ever consider using is
1/2-inch sq shank. Most likely tool is 1/4 inch sq HSS as this
is both cheaper and easier to grind.
The following may be of more interest to the RCM people than the
AMC people (although the keyway question was asked in AMC).
As you may recall I have been exploring the interest in armstrong
[hand powered] shapers for occasional use.
As I was planning the prototype while setting in the shop
drinking a root beer, it came to me that I already had far better
machine slides that I was ever likely to build, namely those on
the lathe.
After some additional consideration and another root beer, it
appears that the same pieces, although assembled/installed in
different configurations, could provide both a keyway
cutter/broach for work in the headstock and a light duty
armstrong traveling head shaper.
In many cases it appears that a small shaper, even if hand
powered (and in some case particularly if hand powered,
permitting delicate operations on small parts such as sight
bases), would provide more functionality to many home shop
machinists / model makers than a milling attachment, in that the
need for special tooling/fixturing is minimized, and the control
is better. Indeed, with only a change in grind [rake/relief],
the same HSS tools can be used on both the lathe and shaper, and
with a little care the tools can easily be resharpened. Even for
the maintenance machine shop this could be a handy, even life
saving, addition as more spare parts must be fabricated because
of unavailability or excessive lead times. Many operations that
are trivial with a shaper and a hand ground tool bit are
difficult with a vertical mill and may require a custom cutter.
Of course the production rate is much higher with a mill and
multipoint cutter, but when you are only making one, the original
part was made with a shaper, there is 2 weeks lead-time on the
special cutter, and the factory is down....
The basic thought is to bolt the shaper ram to the cross slide
and use longitudinal motion toward the headstock for a key
seater/broach and toward the tail stock [must be removed] end for
a shaper. The cross slide is used traverse the ram and tool
across the part. The compound on the ram is used to adjust the
vertical height/ depth of cut as a shaper.
Assuming there is a shaper ram available, the problem is then how
to power this lash-up. A review of the old pictures of similar
universal style machines gave several hints, but these appear to
be overly complex, and naturally enough don't incorporate
components that were developed later.
If armstrong power is used, many of the complications with simple
linkages such as changes in stroke length and mechanical
advantage disappear as the operator can pull the handle a little
farther/faster as required.
What I now envision is a block that bolts across the bed of the
lathe (not on the ways) to which a lever is mounted. For key
seater operation the block mounts to the right of the cross slide
with horizontal lever action. For shaper operation the block
mounts to the left of the cross slide with vertical lever action.
In both cases [different] lever extensions will be required for
convenient operation. Motion is transferred from the lever to
the cross slide through a block that bolts to the cross slide and
a threaded rod [allthread] with a ball/Heim joint on each end.
Gross stroke length and mechanical advantage is adjusted by
moving the ball/heim joint on the lever. By using ball/heim
joints, any problem with binding due to cross slide movement
relative to the lever is eliminated at the cost of some changes
in mechanical advantage, which can be minimized with a fairly
long rod.
On my lathe at least, the tail stock end is well finished, and I
can bolt a vertical plate with several tapped holes and some
guide pins to it, although this will required drilling and
tapping two or three holes in the bed. The guide pins are to
keep an inexpensive [Enco] right angle iron in a known
orientation, and the tapped holes will allow bolting it at the
desired working height. If an aluminum sub plate is installed on
the angle iron, and faced with the shaper, this should be true.
The vertical plate and possibly the angle iron/sub plate should
be able to stay attached, as they won't be in the way.
Not the thing for any type of production, but should be very
handy for one-offs or delicate work. Should be an easy/quick
change over.

George,
I know someone with a cute little bench shaper that I think would be willing
to part with, considering he doesn't have the slightest idea what it is,
except I told him it's a shaper.

The guy is my brother-in-law, I don't know if he even has an email address.
But I'll get in touch with him and if he wants to part with it I'll take
some pictures of it.
