I've machined silicon bronze shafts for a boating buddy and found it
fun.  It makes very pretty ribbony swarf.  IT's tough, similar to
SS.  For slitting saws just use any speed/feed table and use the
diameter of the saw.  With a 3" saw, you'll end up pretty slow.  HSS
should work fine, especially with coolant. If you don't have flood
coolant, squirt it frequently with some light cutting oil. I often
run slitting saws very slowly so that I can just squirt coolant onto
the top of the blade and let centrifugal force feed it in.
  Cheers,
Jerry

I have a Rong Fu 45 and the weights should be similar. I have weighed
all the compoments at one time or another. I don't have the exact
numbers infront of me but I can provide you some targets.

Approximate weights are:
Motor 50 pounds
Head without motor 200 pounds
Y axis saddle 50 to 75 pounds
X axis 100 to 125 pounds
Column 125 to 150 pounds
Base 75 to 100 pounds

Most of the weight is in the xy table assembly and the head. If you
can get a buddy you can leave the column connected to the base and
move it into your basement. If you are doing this alone please don't
cut corners and break the machine down to pieces you can safely carry.

Let me know if you have any more questions.

That is great news.  It sounds like it will be much less of a problem
then I had feared.

I have been hesitant to get a RF45 based upon the overall weight.
While I have moved a 250# tablesaw, 200# bandsaw, and 280# jointer
down to the basement by myself, the 800# shipping weight of the RF45
definitely gave me some concerns, and steered my attention to the much
lighter weight X3.

Now I just have to decide between a Lathemaster ZAY7045FG ($200 S&H)
and a WTTool ZAY 7045M (90 mile drive to pickup).

The RF-45's and clones are in demand. I was in Wholesale Tool in Indy
Friday and they said they did not have any in any of their stores. And
Lathemaster has been out for months.  The ship from China must have
run out of gas.

My DM-45 clone has a clear tube that comes out of a fitting on the
right side of the top of the head.  This tube crosses over to the
other side of the head and back into the top of the case.  What
function does this serve.  I thought it might be to carry oil over to
a different area of the head but the tube has never had oil in it.
Can someone enlighten me as to it's function.  Thanks in advance.

As far as I know, it is a drain hose so when you turn the head upside
down to drain out the oil, you can put a bucket under it.  Some of the
clones have a drain plug in a back lower corner, but mine doesn't.  It
can also function as a breather.  I've never seen anything in mine either.

Thanks, I kinda thought it might be a breather also but didn't think
about using it for a drain.  As far as I know, my mill doesn't have

I use my milling machine for longer parts.  In order to do this I set
up two milling machine vises.  I purchased two 4" Kurt Clone vises but
they do not line up.  The vise on the left is off by about .42.  I was
wondering what the proper procedure would be for making the two vises
the same.

Thank you

OOPS! sorry for not making myself clear.  The heights of the two vises
is right on.  The back side of the vises is where the problem is.  If
I use an edge finder on the one vise, move the table over to the other
vise it will be off by .42.  I want the two vises in a perfectly
straight line.  I am not sure how to answer your simple question.
Would this be considered square to the table?

Anthony

May I assume you don't have .42" of runout on the table <g>?

Also, may I assume the problem is that you're attaching the vises
with t-nuts and bolts, that one vise is off by that amount, and
there's not enough wiggle room to move it that much?

If so, then you have a couple of choices:

- Rather than bolting both vises down directly using t-bolts, you
will have to clamp one vise down instead. If for some reason you
can't do this, then:

- Cut out a ~0.42" thick shim appropriately sized and drilled, and
insert it behind the rear anvil on one vise. That should get you
close enough to square it up.

If your using keys on the bottom of the vices, then
you will have to make a set of off set keys to align
them. or remachine the keyways wider, and make new
keys.

I recieved my 6" Rotary table today from Wholesale Tool.  I am happy
with what came out of the box.  No grinding, a tight rotary action, of
course the usual bondo and heavy paint but all in all a good $100
investment.  Only complaint, absolutly nothng in the way of
instruction or any form of paper work.  But for the price I can live

Quill                18
Quill auto feed      35

Vise                 54

My unit is a KDM-30 from 1985, this is what mine weighed, I'm sure
they varry from year to year...

The tube is a vent/oil overflow, sometimes is actually goes somewhere
(nowhere important), sometimes it's simply a cap with a hole in it.

The biggest reason it's needed is incase the oil foams, this way it
comes out in a controlled fashion, otherwise it might come out in a way
that could damage a seal or such.

Hi Aaron,

I'm no sure this is the case. For example: If the geared head contains
say 1 gallon or air and one gallon of oil then after you churn it up
to create the oil foam you still only have the one gallon of air and
one gallon of oil. So its not clear how a seal would be damaged due to
foaming. Foaming the oil will not increase the pressure in the geared
head. Increased temperature would cause the air to expand, possibly
causing a slight increase in pressure.

The tube arrangement may be something to do with venting the case when
the head ir rotated 90 degees for "horizontal milling". But from the
desription I don't see how. My RF 40 clone has a normal plastic
vent/breather and I have not yet worked out how to turn the head 90
degrees without pouring the contents of the geared head all over the
floor, other then removing the vent and plugging the hole.

Phil Burman

Philip,
If you are confident in your argument, then I suggest that you take a
kitchen blender, fill it with a bunch of stuff, place the lid on top.
Do not clip it on, just place it there and press the PUREE button.
Since the foam has no pressure the contents will not fly into the air
and splash your ceiling.

No offense intended, but this little science experiment may be enlightening.

cheers,

Does anyone know where I could get a set of plans for a Slotter
attachment (to fit onto quill) and/or a rotary cros slide attachment
(like Volstro makes & attaches to quill) for milling circular grooves?

Or alternatively where to buy either inexpensively.  Do not have the
2,000 to 3,000 desired for new kit.

Eric

Well ... I bought one of those enco swivel base vises everyone is
ravin about LOL ..

I came in a box which was inside another box with NO PACKING
material ..  lol can you believe it ..

It had dings in the base that I had to take out ..

ok ..  question is .. whats good enough vs should I call them ..

indicating the vise bed, lengthwise .. its great .. less than 0.0015

can't complain about that ...

HOWEVER, across the bed its out almost 0.005"

and its not the base ... thats out .. its the actual vise..

should I call them ? or is that the best I should expect and
have to take it to my friends house and put it on the surface
grinder ??  ideas? thoughts?

funny thing is .. the base is parallel to top of the vise jaws
LMAO ..
lot of good that does me ..

Foam has pressure??? Well It doesn't. The reason the lid flies off the blender is the vortex created by the cutter, pulls the contense down and up the sides where it will push the lid off... The reason the seal leaks is because it's a bad seal or sealing surface. For a oil to turn into gas the temp would have to 450+ deg so that's not what's happening either. If the gear box was completely sealed heat is the only way it can build pressure. Here's a experiment for you... Put some soapy water in a pop bottle and shake. Watch out it might blow... As you will notice it will be full of foam and no pressure. Come on...
