I remember someone talking about this awhile ago but i could not find the old info.


opinions on 3 in 1 mill/drill/lathe
--------------------------------------------------------------------------------
I have been looking at a 3in1 machine because of very limited space and cash. the 3 machines i am looking at are:

Harbor Fright 1299.00 FREE shipping
Shoptask 1895.00 plus shipping
Smithy 2199.00 plus shipping

the shoptask and harboir freight look exactly the same in the pictures and all of the specs are exact except for the shoptask has 2 motors and comes with a table and some extra tools.
Do you guys have any opinions?

thanks
Chris

To use one of those well, I think one has to be a superior machinist, bordering on a magician.

For one thing, they do not have any controllen downfeed of the spindle or controlled movement of the table in the vertical. This makes it hard to say take a fixed amount of material off in the milling mode.

If it was me, I would shop around for a used lathe and a Bridgeport type mill. Done right, you could get both for less than the $2100 Smithy and have real equipment.

Also, take a look at the equipment sold by Grizzly (http://www.Grizzly.com). We got one of their combo lathe/mills a few months ago to add the capability of making metal components for our F2000 and other projects. As we have all our equipment and race car in a one car garage and a small part of the cellar, we could only get one that we had the space for. We settled of their Model G4015Z. It is not the most accurate thing on the planet, but works well and is accurate enough. As my driver, son and machinest says: "We are not makng a rocket ship, parts are parts." He had never run a metal working machine before and has had no problem operating it or devising fixturing methods. We did not need a drill, as we already have a floor standing one to go along with the hydrolic press, gas welder, Datona TIG welder, fiberglass body/wing/diffuser fab. stuff, etc., etc. Grizzly has other larger models if you need the capacity and have the space (G9729 & G4791). However, take a good look at the size and weight of the machine to make sure that it will not only fit, but that you can put it on its table or base. Ours weighes in at 500 lbs. unboxed. We had to use our engine crane with a special extension to lift it high enough to both get it off our truck and put it on the table we made.
If you procure one from another manufacturer, at least get their catalog. They have loads of accessories (you are going to need some of them) at reasonable prices. In any case, have lots of fun with it. You will be surprised as to how handy it will become, even for home defense projects.

I've had a Smithy 1220 XL (next step down from the Granite you mention) for about 7 years, and I'm pretty happy with it. Yes, I would prefer a 'real' mill and a 'real' lathe, but this fits my space, and allows me to do a lot of things I couldn't otherwise do. What surprised me for the first couple of years was that I used the lathe function at least 3 or 4 times as much as I did the mill/drill function.

The Granite is a useful improvement in that it can powerfeed the table in one direction when using the mill. I haven't really missed a vertical powerfeed.

The biggest limitation to accuracy are the machine rigidity and the precision of the moving parts like the table and spindle. The Smithy is only ok at best, but most of the time that is plenty good enough. From looking at the pictures, and some limited time looking at other models, I tend to think that the Smithy is at least as good as any others and better than most.

Don't forget that even with the tooling packages that typically come with the machines, you'll end up spending another $500 to $1000 on tooling and measuring equipment in the first year that you own it if you use it much.
