If there's a great concern regarding the correct depth of threads there's another way to do it.? The motion of the compound when it's set over to 29.5 degrees can be approximated by two separate

The motor controller may not be adjusted correctly:? or the controller is a POS.? A good motor controller uses feedback to maintain the RPMs under load. Or perhaps you don't know your own

Paul, the power is very low when the speed is turned low. You may want to try and hold it while someone slowly increase the speed. These motors have poor torque at low end.

Sharpie may last 30 seconds. I like the look of manufacture type dial. My second lathe had most of marks worn off and I used a center punch to fix it look tacky Dave Dave > > >

I have look dog clutch but I have never seen any manufacture use a dog clutch. Even the automatic type still used a gear on the screw for engagement of haft nut. Dave

I like direct dreading / diameter reading dials What is your cross feed screw TPI or mm? Can be simple to do Dave

I for one would be happy to purchase replacement dials that measure the diameter change, rather than the radius.? One less thing to remember as a novice.

It is a discussion on standard and direct reading dials,? and how too. I started out with standard reading dials and new lathe I purchased in 1976 had direct reading . For it was big change for

Rather than building a thread dial for metric threading (needs multiple gears) you might consider building a dog clutch - it works for imperial and metric, eliminating the thread dial.? You can

There were special lathes made for this that were very appropriately called "armature lathes."? The lathes were small and didn't have much power (didn't need much) but the swing was big enough to

Or maybe you could get really bold, join the rest of the world and stop mucking around by reading the dial as intended.

No offense to anyone who's considering this, but Instead of changing the dial, why not just learn the principles involved in the normal dial. Taking a certain amount off the radius of any cylinder

Here what looking at can see any mistakes?

I have had to go back forth all life . Direct read they found machinist make fewer mistakes. For high precision turning I use a Starrett dial indicator with ?" shoke and reads to 0.000,1 work great
