Re: Saddle/Carriage adjustments
I remember Ted Hansen's article about correcting the carriage when it appeared in Home Shop Machinist. If the book is the same, I was not impressed. In the HSM article, Hansen designed an additional

Re: Saddle/Carriage adjustments
Bruce, it is not being a broken record when what you are saying is worthwhile advise. And I completely agree that Ted Hansen¡¯s book is very worthwhile and very reasonably priced. Check out

Re: Saddle/Carriage adjustments
Hi Bruce, I have that book. What you are talking about is in chapter 5. I've considered doing that but being a newbie I've been a bit apprehensive about trying some of the upgrades/mods I've read

Re: Saddle/Carriage adjustments
Thanks everyone for the replies on this. The backsplash is still in place. I'll remove it and see if I can adjust the carriage so it moves easier once I have some more time. Stan

Re: Unwanted taper when turning

Re: Unwanted taper when turning
I agree, it sounds like the cutter is "not dubbed" on top rake as we used to call it, grind it neutral correct and it shouldn't "suck in", same idea with drill bits in brass and bronze, the taper you

Re: Unwanted taper when turning

Re: Saddle/Carriage adjustments

Re: Saddle/Carriage adjustments
Certainly begin by looking at and adjusting the saddle.? ?The saddle adjustment is a rather crude arrangement - you will have to remove the apron and the back splash (if still in use). -- Lone Tree,

Re: Unwanted taper when turning
Judging from what you have said, my question is ¡®are you using a lathe tool designed for steel and having top rake¡¯? If so, turning tools for brass should be 0 deg top and side rake ie a flat top.

Re: RideTheGearTran has a new feature
For the standard of threading that most of us machine, the easiest method of finding out tap drill sizes, is to look at a chart ! The next easiest is to subtract the pitch of the thread from the

Re: RideTheGearTran has a new feature
"real engineers" are likely working with metric holes and you don't need a table to figure stuff out. It is simple enough you can just remember it for common sizes. There are not so many metric drill
