I recently bought a boring head on eBay which happened to include an
Everede boring bar. This bar uses replaceable 3/32" triangular
inserts which seem to be tool steel. I touched up the included
insert and found that it produces a much better finish than the
brazed carbide bars I've been using.

Are these little triangular inserts available and if so, where?

Carbide tip tools (regular tools and boring bars)don't produce a good
finish for me. They also seem to develop tiny chips on the cutting
point fairly quickly (which may be why the finish is poor) and I've
also had larger chips a couple of times. I've read that carbide
works best when taking heavy cuts and that light cuts (which is my
normal use) don't work as well because the thin chip applies force
close to the edge. I've also had poor results when re-sharpening
carbide -- the edge seems more fragile afterwards and rapidly
develops chips while turning mild steel; the finish is so poor that I
try not to use carbide on aluminum.

Based on the above, I'm shifting to cobalt steel bits but would be
interested to find out if there is some error I'm making in the way I
use carbide tools or if others run into the same problem using them
on minilathes?

The trouble is the future is always now! I got rid of the huge monster
because I never needed anything that big and the 7x12 was going to do
everything I needed now. Once it had gone, I needed the big one, (:o|/
especially for milling. So a new Mill is on the cards, I am just waiting
until I can get the conversation round so that it is my wife who suggests
it (:o)

It seems there are at least a few of us who enjoy the ease of using
DeltaCad. I have been using version 5, the newest I think, for about
one year. I also have Autosketch and need to refer to the user guide
for help in almost everything I want to do. It is a nice drawing
program but unless one works with it on a daily basis, it is
complicated.

To get back on track though, my DeltaCad quit suddenly and locks up
the screen requiring the "three finger salute" to get back in
business. All else on the computer, including Autosketch worked as
always. My first thought was to reinstall the CD for DeltaCad
thinking it would overwrite the program already installed. No
improvement. After talking to myself and others for a few days I
uninstalled the DeltaCad Program and then reinstalled it and all is
fine.

If yours should quit someday maybe this will avoid some fretting.

Why worry about it? You have already set a course and done the majority of the work/spent the money. If the part is within the capicity of your machine use it.

The 7x machnes are somewhat larger/heavier machines with threading capibility. They usually need some tuning by the owner to get the most out of them. Both machines have huge support groups and readly avaliable parts/accessorys (although sherlines are a bit expensive.) so that should not be an issue.

Smithy for less than $1,000. Now I know $299 vs $1,000 is comparing apples

than a grand, if you have the bucks?

Cause those dual purpose machines are not very good mills, not very good lathes, and you have to tear down your setup for mill to do lathe and vice versa.

I looked at the smithy web site, I assume the model you are talking about is the 1220 on sale in a flyer or something since that is their cheapest model. Reading between the lines and looking at their poor quality photo it appears that the 1220 does not have half nuts. and cannot cut left hand threads. Are they embarissed about how the chuck is mounted? Cause they don't seem to say on their web site. Lowest spindle speed on the lathe is listed at 160 rpm which is to fast for a lathe with a 12" swing.

Would't it be fair to say that the build quality of the Smithy compared to
the Homier would be at least one level better?

Who knows? they are both made in china.

And, unless you're Norm

Abrams with a 40' x 60' heated, dedicated shop, wouldn't it be nice to
have a lathe and milling machine in one, small package?

If you are really in a small shop setup then the fact that the smithy weighs approx 400 lbs will count heavly against it. Alternatives in individual machines are movable by one person. Renting? think about moving that 400 lb machine. (by moveable I mean one person can pick it up and walk away with it.)

Plus Smithy throws

in lots of extras, a video, etc.

Yawn.
If you get one of these be sure and budget for the $275 tooling kit(only place I know to get a 4 jaw chuck that uses their secret mounting system.)

Supposedly Homier will be back in town in two weeks, and I'll probably
take the plunge at time, if they bring one of the damn things to the show.
But I could be persuaded to save my hard earned scratch for the Smithy if
it's "better."

There is a 3 in 1 group or 2 you yahoo you should look there if you want to hear something good about these machines. Try google/groups for endless debate on the subject in RCM.

Regards
Bob (who feels like he has been trolled)

I tried to buy a $299 Homier 7 X 12 lathe at the big tent sale in Glenns
Falls, NY yesterday. It was advertised in the big newspaper circular as
usual, however, when I got there they had none; they didn't bring any this
time. This is the second time I've had no luck in trying to buy this lathe
at a Homier event. The other time the place was such a mob scene I wasn't
able to make the purchase either.

When I got home last night I dug out my lathe file (I've been thinking
about getting one for a long time) and noticed that you can get into a
Smithy for less than $1,000. Now I know $299 vs $1,000 is comparing apples
and oranges, but, please tell me, why would you NOT want a Smithy, at less

Thanx for the tip. I went to the cad site and d/l the program. It
looks like I will use it. Again thanx for the direction.

Sorry if this is a repost, never saw my first reply.
I've been very happy with Pro&#92;Desktop Express from PTC
<>. Under their pages for Pro&#92;Desktop, they've got a
'Learn & Trt' tab that has a link to download the express version. It
apparently doesn't have all the features of Pro&#92;Desktop, but it certainly
meets my needs. It requires registration to get a key, and they also
mentioned either to need to re-register or re-download the program every 6
months, which could be bad if they decide to stop offering it, since your
current version would stop working. But, overall, I have been very happy
with it.

I found the following message again in the Prints_and_Plans group.


Many Australian schools are using Pro Desktop software. It is a
quite good CAD program and is easy to learn. The site information
states:

Pro/DESKTOP Express
This is a 3D CAD package developed specifically for engineers and
designers who do not need the full functionality of Pro/ENGINEER.
The web page is


There are significant support sites for the software eg.


Don't know anything about the program. I looked at the site but haven't had
the time to download and try. Hope this helps.

I use Delta Cad & have been very happy with it.

I've recently been using a program called Pro/Desktop Express. It's a more
limited version of ProDesktop, but it has certainly done everything I want
it to do. Available for free from <>. On the info page
for Pro/Desktop, there's a learn and try tab that has a link to the
download. You have to register (for free) and get a key. And supposedly,
after six months you have to download an update or get a new key (can't
remember which), which means that there's always the possibility that
they'll decide to stop distributing it, and your current copy won't work.
But, it really is a modern CAD package, from what I've seen. Be sure to
check out the tutorials in the help files. After trying other cad
packages, this was the first one I really liked.

Hi Charlie,

I haven't checked out the one recommended by Bob, but I will. In the meantime, here's one that I have been using for several years. www.dcad.com It is called DeltaCAD and I swear by it. It is very easy to learn and use. There's a 45 day free trial, then it costs $39.95. They claim to have sold more than 150,000 copies.

Charlie Starks

You may want to try Pro Desktop Express. It is free but you do have
to register in order to get it working. You can find it at this link

Well folks, I fired up my lathe for the first time. I

started

out

by squaring the ends of on a scrap piece of brass, and then

cutting

two small grooves on one end. Then I used the center bore,

and

place a small hole in the end. My son thought I was making a
shotgun shell. At least it had SOME semilence (not sure if

this is

a word) to something real. I did however discover something

that

sucks about this whole thing, metal splinters ;-)

I have just ordered a face plate, a 4 jaw chuck, and a few

other

items. Once the faceplate comes I can try squaring up the

flywheel

for my Stuart D10, and the 4 jaw will allow me to start

getting

the

base ready.

I'll keep you all posted.

You might try turning the tool upside down and running the spindle
in reverse, it throws the chips down instead of showering you with
them. That is if your turning brass..
