View Full Version : Bycatch

The following bycatch appeared on deck after I was forced to use a
net rather than my customary hook during a recent outing.


http://www.slalom4me.com/imaged_a01/jpg/other/tools/lifts/2012.05.19_Chief_EVCM100D_02.jpgDidn't know what it was but concluded that it looked like a wall or ceiling mount.
Appeared to have two sections with four latches to clamp these together,
but I couldn't separate them. Also noticed that it weighed more (48 lbs)
than its dimensions (approx 10" x 16" x 4") would suggest. Initially, the
plan was to turn it in on my next trip to the metal scrap dealer.

Turns out that the device is a Chief EVCM-100D motorized projector lift.

There is a motor and a cable winch inside. It has a maximum capacity of
250 lbs and a maximum travel of 20 feet. After releasing the four latches,
the lower plate descends suspended by two cables paid out from the
winch in the upper case.

I do not have an immediate use in mind for this unit but I anticipate
putting it to work in the shop as a lift for moving work onto the lathe,
mill or perhaps work benches.

Oh, below is the principal catch I set out to land: a Di-Acro #1 Rod Parter.
It has eleven holes from 1/16" to 3/8" in steps of 1/32".

Holy crap you can see that the rod parter is the mother of all leverage tools --- don't git yer finner in there...

--- don't git yer finner in there...Di-Acro no longer seems to offer the #1, but there is still their #2 with
capacity from 1/8" to 5/8". The #2 has the same configuration as my #1,
though I am unsure how much it is scaled up in size, if any.

5/8" ?, now there is some leverage. Apparently, there are or were
powered versions of those, too.

So im curious - is there replaceable hardened insert plates ?

they cannot just be using the casting material to do the sheering right?

It's a very nice looking well built unit.

So, I'm curious - are there replaceable hardened insert plates ?Exactly right.

My photos do not have sufficient contrast to show the difference in material
but there are separate disks of tool steel, one in the base and one in the
articulating lever arm.

These are thick enough to allow numerous resharpenings and they are
reversible to extend the period between resharpenings.

Here is an exerpt from the Operating Instructions (http://www.neme-s.org/Shaper%20Books/DiAcro/1_Hand_Rod_Parter_Manual.pdf)

"The Di-Acro Rod Parter No.1 is equipped with cutting heads
that provide eleven holes graduated in size form 1/16 to 3/8
diameter in steps of 1/32. Cutting heads of heavy alloy tool
steel, properly hardened and precision ground, assure a high
degree of accuracy and are reversible to offer double service.
They are easily removed for resharpening and can be quickly

The 3 pg document includes an exploded view parts diagram.

Yes, it works nicely. What's more, by removing the handle and the
gauging rod, the parter becomes very compact.

There isn't much to keep an HSMer from duplicating it. There have
been a few threads about bolt cutter blocks on the forum and I am
posting about the Di-Acro in part to offer a variation on the themes
presented in those threads.

I bought this one knowing it appeared to have been repaired. The
repair seems to be well done and to have lasted for some time. I
am confident that the parter will serve well for my purposes.
