Wanted: Vertical Milling Head (Burke?)
I have the same mill with the vertical head you're looking for and all the accessories. Not sure what the condition of yours is but you're interested in the whole machine let me know.- bobbyf

WTB 10 or 12" Rotary table
Just catching up - I appreciate the replies. From what I've read, a 12" table is in the 150lbs range. That's a lot to move around on the mill. I'd be scared to go any bigger. Are there any style of RTs that weigh less than others?- bobbyf

The correlation between speeds, feeds and depth of cuts for a better finish ??
I'm a newbee myself and went through this last year. I can pass along a few things I've learned - could be wrong tho :) Look at the color of the chips. Lots of info out there on what to see. I seem to get better finish with a modest to deep cut. -

WTB 10 or 12" Rotary table
I'm not familiar with Tsudakoma. Looked them up and everything I saw was CNC. Made me realize I didn't provide very good info. I need a manual table. I'd prefer one that mounts horizontal and vertical but can get by with horizontal only if the situation is right. Sorry for any confusion, Bob- bobbyf

WTB 10 or 12" Rotary table
I'm looking for a decent 10 or 12 inch rotary table. I'm in Lynchburg VA so LYN, Roanoke, Richmond, Raleigh NC, etc. areas will work. Thanks!- bobbyf

OT- Favorite pistols to shoot
Second on the Springfield 1911. I don't know why but I enjoy shooting the SA more than any of my other 1911's. FWIW, for range use I also like the wheel guns.- bobbyf

Spindle Speed in Dead Zone
I'm all new to this so I'm just using the program as a starting point. I don't mind experimenting. What I'm asking is what should I look out for that will tell me I'm doing something wrong? -

Spindle Speed in Dead Zone
I apologize for learning out load - the more I play with this calculator the more it seems to be varying everything else to keep the cutting force and chip thickness constant. Is that right? does that mean I can use any value that makes the specified chip? -

Spindle Speed in Dead Zone
This is where I'm totally ignorant. The calculator lets me vary the spindle speed. If I start with 3" width it recommends 582rpm and 16in/min. If I manually increase spindle speed to 1000rpm the calculator says to feed at 27in/min. that seems like a high feed rate to me but I honestly don't... -

Spindle Speed in Dead Zone
I figured it wouldn't be that simple. I'm cutting mild steel with indexed facemills. The worst seems to be an ISCAR FS45ST3.0 with with SEKT43-AF-R inserts. The calculator recommends 582 rpm/16in/min at 3" width and .03" DOC. This is supposed to take 1.16hp. In high range my 3hp motor... -

Spindle Speed in Dead Zone
Hi, I have an Acer 3VS mill with a digital head. I'm new to milling and have been using FSWizard for calculating speeds and feeds. My mill runs 0-450 rpm in low range and is advertised at 0-4500 in high. My problem is that some of my face mills call for using 600-650 rpm and at that speed... -

Advice on insert style mill cutters
That's the plan - 45 degree cutter that takes SEKN inserts. I've been poking around. So far I've seen Shars and the cheapo ebay in that configuration. Still looking. -

Advice on insert style mill cutters
I was just playing with a 3 insert 45 degree cutter that I has in a drawer. It uses TPU 322 inserts and it worked when facing mild steel tube but the result wasn't what I hoped for. You said the TPU style wasn't good for milling - can you recommend a 45 degree insert that's common and works well? -

Advice on insert style mill cutters
Ahhhh...thanks! For now I'm looking to face off flat surfaces. So a 45 degree cutter that uses the APKT style inserts? I'm starting to see that there are a lot of different APKT inserts so like you said, I may not get the interchangeability even within that style.
