The Hudy cuts the comm from right to left.

McMaster sells some diamond bits for 50 something USD and the are perfect. I have one on my Cobra lathe and I can get cuts "almost" as good as the Hudy.

The PN from McMaster (http://www.mcmaster.com) is:


AL-4 3316A42 $51.67

The L stands for Left Cutting, but we use the diamond part facing down, so this means we need the opposite cutting bit (not the right one as it should be logical). Trust me I know because I had to buy two of them (LOL).


The Hudy Part number for the cutting bit is:

HU101081 Hudy Commutator Lathe Diamond Tip

And it's almost the double of the price.

(EDIT) I almost forgot about the carbide bits that fit. Here goes:



C6 Grade
AL-4 3367A341 $3.57

C2 Grade
AL-4 3367A131 $3.42

I understand that C2 is better for our uses (don't ask me why, but I guess it is)

Grade C-2 The best grade for general purpose use on cast iron and nonferrous materials. Grade C-2 tool bits provide very good shock and abrasive wear resistance along with high load and edge strength. Comparable to Kennametal K68, Carboloy 883, Sandvik H13A, Valenite VC2, and Wesson 2A5.

I have a Hudy lathe with a diamond cutter, after cutting well over 100 comms I still get a perfect cut. The tip under a magnifying glass shows no wear. The cost of the Hudy cutter is less than the price of a single modified motor it is very good value!

When I used carbide I'd get maybe eight or ten cuts at the most before they needed sharpening...

Try dismantling the lathe completely and cleaning out the threads and guides. Sometimes you can get little bits of copper shavings everywhere which can upset the cut quality.

Also when you re-adjust the tension on your guides be sure to do it evenly. I like to adjust one setscrew at a time, get that setscrew so that you just feel an increase in resisitance at the wheel and then back off a little. Repeat for the second setscrew on the same guide, this way you know you have both setscrews set exactly right!

AntonioP,
I got my Hudy Tech Lathe with V-blocks the other day and I order five of the carbide bits you recommended yesterday from www.mcmaster.com I got the bits today, because they shipped it from Cleveland and I tried the new lathe and bits out. All I can say it wow! The lathe is so smooth and vibration free and the bits gave an excellent cut. Thanks for the advice.

Those Hudy lathes are amazing.

With the correct bit they are impossible to beat.

Glad I could be of some assistance.

I have the new Orion lathe and it works great, easy and fast to setup, very smooth cuts. Comes with everything you need, carbide bit, 27t mod slave motor, switch, and wires. I am going to buy a diamond bit though.

Depends on which part of the world you are at. In Hong Kong that sells for around USD 175 with the diamond bit included!

I have a eagle lathe for about 6months now no problems. Every body spends high dollar on a lathe. 70 bucks is just right. even comes with a bit..

How much better is the Hudy lathe over the Cobra lathe. Is it really worth the price difference.
