PEATOL/TAIG: Milling attachment 1220

Milling attachment

Part # 1220

From Taig: The milling attachment is used to hold the workpiece while the cutting tool is held in the headstock spindle. The attachment provides vertical travel of approximately 1 3/4 inches. The dial provides travel in .001 inch increments.

The cutters (end mills) are held in the spindle with collets to provide maximum rigidity. Miniature end mills come with 3/16 inch diameter shanks and various size cutting diameters. The end mills will cut all materials steel, aluminum, brass, plastic and wood.

Milling on a lathe? If you already have a mill, you will find are needed more passes and lighter cut with this attachment.
The attachment may also be used for gear cutting. Check out this video by xynudu on youtube:

OUTSIDE: Making gears at home

Making gears at home is quite difficult and a lot of tools and machinery are needed.

At least you need a rotary attachment for a mill or lathe with a specialized tool (involute gear cutter).
Another drawback is that to cut a specific gear you need a specific size of involute gear cutter, so a complete set (normally 8 pieces, around 100 bucks) is needed.

Chet out this great video by Tubalcain:

Another option is to build a small spur gear hobber machine (project already in the wishlist) like this beautiful one by Jack Hayes:

Also in this case, only the hobber, quite difficult to find, at least requires 80 bucks.

Solution? Not for helical or spur gears, but there is a particular set of gears, called worm gears you can machine at home. 

From wikipedia: "Worm-and-gear sets are a simple and compact way to achieve a high torque, low speed gear ratio. For example, helical gears are normally limited to gear ratios of less than 10:1 while worm-and-gear sets vary from 10:1 to 500:1"
Is possible to find this set of gears in telescope aligning mechanism or in a mill 4th rotary axis. In this set the two axis are perpendicular, and only one is driving.
The drived gear can be machined easily using only a lathe, and the other one may be simply a machine screw with imperial, metric, acme or custom thread. Is only needed to have the a screw tapper.

Check out this self-explanatory video by Dalibor Farny:

Finally a link of great kinematics models. From KMODDL site: "KMODDL is a collection of mechanical models and related resources for teaching the principles of kinematics--the geometry of pure motion. The core of KMODDL is the Reuleaux Collection of Mechanisms and Machines, an important collection of 19th-century machine elements held by Cornell's Sibley School of Mechanical and Aerospace Engineering."

PEATOL/TAIG: Radius turner 1210

Radius turner

Part # 1210

From Taig: The round nose tool bit can machine a radius at the end of the workpiece by swinging around the material. The bearing's inner race on the radius attachment bolts to the crosslide and then the entire base can rotate with the bearing. The rotation is done by hand.

If you want to see a radius turner in action, check out this video from ElationProduction on custom built ball turner for taig.

PEATOL/TAIG: Steady rest 1190

A photo review of the Peatol Taig Steady Rest (Part #1190).

Capacity: 3/32" to 1 1/2 " - 2.38 mm to 38.10 mm

From Taig: The Steady Rest is used to support long workpieces that extend out from the spindle. The support is needed so that the cutting tool does not deflect the workpiece as the carriage is traversed away from the spindle.

If the standard steady rest does not suit your needs, check this awesome work by Joe D Link to homemodelenginemachinist.com

If you want to modify this steady rest to use roller bearing, check out the encyclopedic Cartertools blog:

PEATOL/TAIG: the most beautiful affordable metal lathe

I bought a PEATOL/TAIG because i need a small lathe (despite i have a 7x20 lathe) i can operate in my house. I have known about it from the conspicuous fans all over the world.

Peatol/Taig lathe overview

The Peatol 0,18kW motor, 1360 rpm

Here some links if you want to know more about PEATOL/TAIG:
Peatol Machine Tools: the home of PEATOL/LATHE;
Deansphotografica: beautiful projects;
CarterTools: the biggest resource i know about taig;
LeeValley Instruction booklet;

I received it from Peter of Peatol (UK) on August, and now i'm showing it once assembled the base, the motor and it's fully functional. The motor was blue so i repainted to black.
I assembled also the motor mount from aluminium with primitives dovetails. My version of lathe come with powerfeed already installed and a sturdy block of aluminium for raise the entire lathe.

This is my start package:

1015	Micro lathe with power feed
1030	Four jaw chuck, with reversible, heat-treated steel jaws
1092	1/16"-3/8" Jacobs chuck
1150	Drilling tailstock - lever operated
1151	Needle bearing centre - spring loaded
1160	Spare belt
1161	6 step pulley set (2 pulleys) including Vee belt for 11mm motor shaft
1095	6 piece tool bit set - HSS, left & right, round nose, boring bar, cutoff, 45 degree chamfer
1200	Compound top slide - mounts on cross-slide for cutting angles and tapers - with toolpost
1002	New electric motor - 11mm shaft
?	Drill chuck arbour - attaches Jacobs chucks to headstock spindle
1173	T-bar cutoff tool, height adjustable

Peter form Peatol said me this is a very comprehensive set of components to give a working lathe, and i must admit he was right.
For the base i used a wood block from a ikea countertop (very hard), a drip pan upside down and a wooden frame to finish the base. To lock the lathe and the motor's dovetail to the wood base i used brass barrels in the bottom plane.

A review: this lathe is beautiful, sturdy, small, precise, simple to assemble and use. A must for every workshop. This is only a start because there are a lot of implementations you can do to this little lathe.

The pulley system, note the rubber band

The toolpost, simple and effective

To enable the power feed you simply lock the handywheel 

I think i will replace the spring with a coupler 

The Taig headstock

My home made motor mount with dovetails

The depth stop

I bought also two IGaging Scales (IGaging site), a 6" and a 12" which i've cut to size and mounted on X and Y axes. I've planned to convert the DRO to Yuriy's Touch Dro (Yuriy's Toys Dro) using a tablet and a TI launchpad.

The other IGaging support

The stock IGaging magnetic reader.

With IGaging in this position you lose some x width with tool post installed.
