How do you use a DRO to make a bolt circle on a lathe ?

Do you need a gear, or just an index plate? If you have a DRO on your lathe, it's pretty easy to generate a list of drill spots for a bolt circle of 34 bolts... just search the web for "bolt circle

3D Printing gears: I am going to use a 3D printed gear on a spindle as an indexer to cut an aluminum or cast iron gear on my mill. I hope to make a 34 tooth gear to insert on my 9" Southbend to be

I have trouble at 100% because any inaccuracy in the filament diameter or print path causes an accumulation of bloat. 90% gives the print some "breathing room". Other folks print in the 75-90% range

For anything that needs to take mechanical stress you should set it to 100% in-fill. Since your printer can print ABS, you should be able to adjust the temperature to print nylon, which tends to have

Hello, can you email the pic direct? For whatever reason it says I'm not a group member but am. I always get this error. Thanks.

Perhaps it's my math Jim B,

Now I'm wondering if my math is wrong... Nope, just checked my lathe with a protractor, and measured about 3 degrees. Maybe different lathes have different screw grometries? Thanks!

Not sure where the day went, but... The print had "scaffolding" around it to hold up the overhangs. It all had to be removed. Carefully. Turns out there's a bug in my slicer that makes the

I did, it's a helix gear, just a very slight helix. Also, the gear library I had for the cad software knows how to make helical gears, and the printer doesn't care... made things a lot easier to do

Why did it take 5 hrs to assemble? Thanks

Just an enhancement. The next time you cuta thread dial gear, the teeth should run at a slight angle. About 6.5 degrees, tomatch the lead of the lead screw. Straight is OK sincethere is little
