Project Example: Morse #0 taper blanks are the starting point for many accessories.

What does this tool do? One can cut Morse Taper and Morse arbors easily even on a small home shop lathe. Since labor costs are not an issue for hobby type work, you can make these accessories by yourself for close to zero dollars. All you need to do is setting the cutting angle precisely enough. Our mechanical protractor is exactly doing this for you, making the entire process a piece of cake. Cutting a perfectly fitting Morse taper takes 5 min / piece. Actually, we are crazy offering this kind of tool. Sure one can cut any small angle taper: Jacobs, Jarno, Morse, etc.

Project Example: Center drill -
Morse Adapters.

Further accessories for your Protractor / Taper Cutter

Steel Test Arbor Set
Morse #0 Arbor and Morse #1 Arbor

Reduced length (approx. 1"), steel

Plastic Morse #0 Test Arbor
If you machine your own Morse adapters an arbor for test fitting the pieces properly is essential. The piece is cut in transparent plastic using reamer. Thus, one can perfectly see if the Morse taper fits.
One of these is included in the LASER protractor package.



Adjustable Tailstock Center
(Morse #0 taper to dead center)
Cutting taper in longer and/or larger diameter stock without a center is dangerous and basically impossible. This adjustable tailstock center compensates for the offset when cutting taper by rotating the headstock. Details & images --> [ manual new design ] [ old design manual ]

$59.00 (Shipps priority mail for +$5)

Customer projects: we would love it to see your own projects. If you like, e-mail an image to us. If you agree we would put it up at our website, but no compensations.

Example: Morse taper #0, #1, #2. Cutting larger size Morse tapers is actually simpler on a smaller benchtop lathe than on a full size system.
