winona ph2000?
i would like to start cutting seats on my seat and guide machine.noticed in another post that the cutter body from regis with the lower support was recomended.is my ph2000 machine and the tooling from regis capable of cutting seats in a decent manner?how much would a carbide pilot help?also looking at some cutters from goodson.been cutting seats with stones and using the typical 30,45,60 angles.could someone recomend some good cutter profiles to get me started?will the 4 and 5 angle cutters cause more deflection and chatter then a typical 3 angle cutter?
I've never used that type of machine so I'm probably not the best one to answer your questions.
Yes carbide pilots are considerably stiffer than steel ones, I'd consider them a good addition.
Chatter will always be a certain amount of an issue, this is true with most machines that use formed cutters. Much chatter can be eliminated by proper fitting pilots also by finding the correct speed, feed and some cases lube. The more area you are trying to cut with a formed cutter the greater your chances are for deflection and inducing chatter.
Think I would opt for a seat cutter with the desired angle on each side of the seat, then for any additional angles purchase cutters that match your needs.

Re: winona ph2000?
I have done some research on this. talked to many users and suppliers. I.e t&s machines, regis, goodson, silver-seal and also several machinists. Not sure who had lower guide support. The story seems consistant that sometimes a ph2000 is ok on some heads and not on other. One machinist I talked was acheiving .002" runout on his ph2000. He was by letting the table float a lttle bit. claimed he wasn't having to lap seats after.
.002" runout isin't close enough for me though.
Some I talked to touch up with stone after the three angle cutting.
T&S machines claims to have developed the dead pilot ball drive form tool system. He told me that "IT GAVE EVERYONE A TASTE AND THEN THEY BOUGHT SERDI'S".
T&S reccomends the best set up(besides a dedicated machine) was using a bridgeport (raised with a three inch spacer). Putting a winnona air float table on the bridgeport and then using the dead pilot ball drive form tool system with that. Add up a variable speed drive, 3 inch spacer, used winnona table, ball drive tool kit, a level and it's around $3000 to convert the bridgeport.
the ph2000 could be going for the price of a kit $750-$1000, but may not give the results you need. The problem is lack of quill support . No one I talked to would say a carbide pilot gives much better results in a PH2000 or other similar seat and guide machine conversion.
Maybe lower guide support helps, but I was talking to the owner of t&s machines only a month ago and he did not mention it as a solution.

Automotive Machining, cylinder head rebuilding, engine building. Can't seem to quit
max effort what type of heads was the guy using his ph2000 on? i mostly work on dart 23 degree sbc and conventional dart bbc.i am looking for an easier way to do the valvejobs and dont mind touching up the seats with a stone or lapping.i have found the more complex seats move more air on the flowbench but are a pain to cut all the angles with stones.just looking for something a little faster i guess!
