I checked out their website. The prices seem quite reasonable. I guess now I have to tear into the existing controller to see what I need to buy for the new one.

I am also looking into the Acorn...

Here's what I'm looking to accomplish

Current setup:
Vertical Knee Mill
NASAII iron
Anilam 1100 controller
Controller and servo motors are working fine, but I'm limited on my capability due to...

A long time ago, I remember a photo gallery of the year long move and rebuild of a large (~100 in. swing) VTL. I think they called it a vertical boring mill. I was pretty sure it was in Michigan. ...

Here is a drawing of what I am looking for. I would like to get one pair made initially for test. Subsequent orders will be made in quantities of 10 pair each.

Material for initial will be A36...

I saw this listing on my local Craigslist. I thought someone on here may have a use for something like this. I would really hate to see them not used.

I ran into this problem a couple years ago. Here's a guide to tell you how to draw them:

I don't know if tooling is the issue here. Feeds and speeds, as well as a light cutting oil are important for working with aluminum. If you have a decent endmill available at the shop and let us...

I've successfully used Toshiba laptops. The one I run WF2 on is something like 5 years old and runs P4 2.4GHz with 1GB of RAM, but I don't do large assemblies. It cost me $600 used four years ago,...

Experienced welders rarely have problems with burning out electronics on items they are welding, but it does happen. If it were my machine with the table and controls capable of conducting...

For a long reach application like this, you want the stiffness of a HSS/Cobalt tool bit. Tool bits, that's what they're called. Here are a couple links to a popular supply house and a less...

I am going to advise you to get whatever arrangement you have with the owner of the shop in writing and keep impeccable records.

Here's why:

Just last week, I was subpoenaed to testify against...

I don't have anything to say about this that hasn't been said here:

$100k would be enough if you had a start on your machines (and they were...

Class D fire extinguisher = Bucket of sand

Seriously, that's all you need. A couple of galvanized pails from Home Depot and a big bag of sand should cost less than $20.

As far as coolant goes,...

For me, it depends entirely on the number of posts/holes to be threaded, the time difference expected, and the cost of the tool and/or workpiece.

If it will save 10% on time but eat up that...

Why wasn't the copper TIG welded?

I'm a little confused by your question. I would assume they operate like any other business that sells things and pay taxes only on profit made. The IRS here in the states calls that adjusted gross...

Geof has the way you need to do it. You can either use a lathe or a horizontal boring mill. It would take some work, and a very stiff boring bar. The benefit of the boring mill is the rigid setup...

I am going to recommend www.bearingsdirect.com for the bearings. When I was looking, they were much cheaper than McMaster.

A woodruf cutter could also work. I have used them before to make retention ring grooves in parts that would be difficult to turn.

It's probably worth about $100 in cast iron. So, even if it's not serviceable at all, you're not out anything. I'm sure that there are parts on it that are quite usable for other projects or...

MrWild,

I hate to contradict you, but ASTM A-36 (ASME SA-36) is standard hot rolled steel with a minimum tensile strength of 36,000 psi similar to AISI 1018 in most characteristics (AISI 1018...

OSG Makes some wicked taps. They're pricey, but a great product. You can buy them from MSC or your local supplier. I would recommend the spiral flute for blind holes and the spiral point for thru...

cnczoner,

I just found a site last night while looking for Timken roller bearings.

www.bearingsdirect.com

They had the actual Timken bearing I was looking for at 1/3 the cost of McMaster, so...

mactec54,

What's sad about that picture is that setup probably works extremely well with the inconsistent power provided in places like third world countries. I've been to places where one day...

jcnewbie,

I am going to recommend you get the book Machinery's Handbook (Amazon.com: Machinery's Handbook, 27th Edition (Toolbox Edition) (9780831127008): Franklin D Jones, Henry H Ryffel, Erik...

I am going to agree with millman52 that cutting with LPG will have near identical performance to Acetylene because it's the oxygen that does the cutting. Preheating is another animal entirely,...

There's a big difference between M02 and M03, namely the direction of the drill.

A piece of steel that large flying at me would make me reconsider how much I trust that enclosure.

Yes, salaries vary wildly. In Kentucky, an engineer with 5 years experience can expect to make around $60k.

The Sheet Metal Workers Local 110 pays journeymen $28/hr which translates to about $56k...

Ok, for starters, your RPM looks about right for the material and endmill size. You should be running at least 0.001" per tooth or 0.002" per revolution (36" per min ~ 1m/min), so you need to turn...
