Re: Spindle Plate Land

Craig C. Hopewell <[email protected]>
 

John,
I have not heard of this problem before, but I am new
to the hobby, and if any lathes had this problem I would
have expected it on mine ( 8^) or 8^( - don't know which).

I would want this to be accurate, especially if removing
and mounting the chuck regularly. If under warranty I
would request a new spindle. If not under warranty a
new spindle is available from www.littlemachineshop.com
for $29.95. Alternatively, an adapter plate similar to
those necessary for a four inch chuck could be made.

Is there a better way to center the chuck?

Mike,
Thanks for this information. I called Homier about this drilmill and
Shirley, who is alway extremely helpful but relatively
unknowledgeable, could not find anyone at the time who was familiar
with the drillmill. She did find it on the sale brochure and is
sending a brochure. Hopefully Homier will come to Colorado soon.

Some of this message may be off topic since it concerns the new
Homier 12 Speed Drill Mill. If so, I'm sorry and I won't do it again.
The mini lathe availablity is in the following paragraph.

For any who may be interested, I went to the Homier show in
Bessemer, Alabama this morning (2-4-03) and they had 5 of the
originial 7x12 mini lathes (one box was open and the way wipers etc.,
were on it), two mini mills and two $199.99 Drill Mills as of 11AM.
The $599 mill drill sold before I got there at 9:45AM. The sale starts
at 10 supposedly but folks were already leaving with their arms full
when I arrived at 9:45AM. There was only one $199 Drill Mill when I
left since I bought one. I already have both their mini mill and mini
lathe via mail order. Other than a $100 dust collector and a few
piddly odds and ends, the balance of the show was pretty slim. The
savings on shipping is huge.

Since I haven't seen any other descriptions of the Drill Mill #3989
(3/4 HP Drilling and Tapping Machine), I'll post what I have measured
so far for any who are interested.

This appears to be the same as the 12 speed Drill Mill Harbor
Freight sells. Except it is a peculiar shade of red-orange. The paint
really looks more like some kind of painted on filler glop and is
cracked in places. It could really use a nice new overcoat of (fill in
your favorite color here) paint.

Particulars:

-No vise
-MT2 spindle
-5/8" drill chuck
-Milling Table is 6" x 16 1/2"
-Travel is ~ 4 1/4" x 9" (the 4 1/4" is an estimate of where it
would hit the column if it were installed.
-The backlash checked 0.008" on the x axis and 0.011" on the y.
-The handwheels are pitifully marked with stick on paper labels
showing 1-4 with no zero and ten minor divisions. I measured 4mm
travel per turn for each axis.
-Motor is 3/4HP UL Listed. I haven't gotten the head out of the box
far enough to read the motor label yet. But the UL sticker is on the
top side and the literature says it is 3/4 HP.
-The manual stinks. No specs at all.

The table movement is far smoother than either the mini mill or mini
lathe. I bought it to do a CNC conversion when time permits. I'm
intending to try it with the existing lead screw first with perhaps a
mod to adjustable nuts to get the backlash down a little first. For
$216 out the door it's a much less scary thing to try if I should
attempt ball screws later. Plus I'll have the mini mill to work on it
with.

Re: Correcting Height Alignment

 

Most likely, the work is springing away from the tool
at the center point where there is the greatest amount
of flex. This will happen if the work is relatively
long (thus limber) compared to the diameter. For
example, a piece 8" long and 1/2" dia would have some
flex near the center, while a 1" dia. piece of the
same length would have much less.

Re: Correcting Height Alignment

 

Try making a couple of passes without advancing the tool. It
sounds like the work is deflecting, which a follower rest will take
care of. Repeating a finish cut without changing the tool setting
will also take care of it. You'll be surprised at how much cutting
is done on the 2nd pass! Then again, .002" is my idea of a heavy
finishing cut.

Point well taken Roy, although I have contacted Homier several
times, and wonder if I do exercise the option to return the lathe, if
they will give me the "newer" style 7 X 12, or another of the older

older Homier does have some additional features not found on the
newer style: oil ports, way wipers and lead screw extension. I will
attempt to shim the headstock, as this seems to be far less
complicated than cutting the tail stock base, as the tail stock does
indicate true in all three planes. Regards, Nick

Re: new machines

 

Well, I guess if you had both models sitting side by
side you could say that the older model is dark blue
and the new model is light blue. But without the other
one to compare to, you could say the the new one is
dark blue.

Here are links to the
reviews of the new and old style:

The quality varies from machine to machine, but from
what I have seen and heard, has steadily gotten better
over the last few years. The new ones are usually very
good right out of the box, although they still require
some adjustments and TLC for best performance.

The early Homier lathes were from a different
manufacturer. The good ones are pretty nice, but I
heard that they had a lot of QC problems and I believe
that was a factor in why Homier switched to the Sieg
brand.

Re: Correcting Height Alignment

 

Well, you needed an excuse to buy a mill anyway. You
won't regret having one.

Good Afternoon All:

Finally got most kinks out of my alignment

dramatically
improved,

lower
than the
tailstock.
What would be the preferred method of
correction?
Should I shim the
headstock, and if so, is there a difference in
brass vs. steel
shims?
Or, should the tailstock base be carefully cut
down? Replacement of
the parts has improved accuracy greatly, but due
to this height
difference, I get a slight chatter and taper
0.0055" on a 9.5"
length
of stock. I attribute the chatter to the height
difference as the
tool advances toward the headstock. If you
advise
that shimming the
headstock is the preferred method, I would also
consider upgrading
the spindle bearing to ABEC-3 units, in
contemplation of eventually
using a 4 or 5" 4-jaw chuck on this lathe. Have
any of you changed
these bearings? If so, any notable difference in
how the lathe
sounds/operates? Any suggestions/recommendations
would be greatly
appreciated.

Re: new machines

 

The quality varies from machine to machine, but from
what I have seen and heard, has steadily gotten better
over the last few years. The new ones are usually very
good right out of the box, although they still require
some adjustments and TLC for best performance.

The early Homier lathes were from a different
manufacturer. The good ones are pretty nice, but I
heard that they had a lot of QC problems and I believe
that was a factor in why Homier switched to the Sieg
brand.

Re: Correcting Height Alignment

 

Shimming is valid; I suspect they'd replace your lathe with
current production, not an exact duplicate of original. Shimming is
also much easier to undo than cutting ;-)

Re: new machines

 

I guess it all comes down to this: If money and space were no object, then a brand new South Bend 10" or one of the other lathes out there would fill the bill. On the other hand, for hobby/limited use, one of the bigger lathes is a considerable investment, not to mention cost of shipping and setting up such a machine. Given the small cost of these asian made lathes, even with their inherent inaccuracies, one would be hard pressed to justify purchasing a larger lathe, unless the intent is a start-up manufacturing shop, or serious production work.
