we tested about 8 grinders and the one I have had the best results as far as finish and run out then the kwickway, and 3 suix's were all out about the same witch ws too much for anything I wanted to do, there good for roughing a cut down valve befor doing the final cut on a good machine. as far as seet work alot of that is the operator, Ive seen perfect equipment do a effup job and the neway style was the worst I had seen( I have a set of neway thingys I have never used, but I got them out of the hands of a VW shop that was fucking up heads with them. in diferent shops Ive seen many pilots are bent, and somany are just plain dead.and the chucks are dead as well as the holders. YOU HAVE TO TAKE CARE OF THIS EQUIPMENT BETTER THAN YOUR DICK!!!keep it clean!!! flush it out before and AFTER you use it!!!! dont beat on it!!!! true the stones as much as it takes!!! like a few times per seat and once before the last cut!!!! learn how to dress the stones!!! use the right stones!!!! .. the old peaterson pos we got new was a pos when we got it and I chewed on the factyory reps ass for it...didnt do any good, he was trying to blow some of that cali smoke up our asses so, me being me..I farted in his wheeties!!!! |

Kinda leaning towards the new3acut single blade system then keep an eye out for a good deal on a sioux stone setup. I would probably use the stone to clean up the 45 occasionally. Got the mill, may as well use it. My tools get well taken care of. My dad drilled that in at an early age. |

USED sioux kit......steer clear. Good chance you'd end up paying big bucks for worn out stuff.
Like buying used carburetors, they are either cores or ready to run, not much inbetween can be claimed or believed.....because everybody has a different "opinion" of the condition.
I bought a great stone dresser on ebay for oh... 90 bucks I think, and the description said "works as it should" but actually it was rusted solid, pilot was worn down .020, and the dresser diamond was wrong.
Of course, I assumed all that from the get go, from the looks of it, but wasn't sure if I should leave good feedback.
Stone dressers, stones, probably ok to buy used but the other pieces......you might be just as well to buy the copies made in india as chance used. I have two NOS sioux shorty "aircraft" stone holders I bought, still in box...... but the lube turned to wax, and they have an odd 1/2" hex drive, rather than the newer star drive........is that the stuff you used years ago? :D |

to be honest with you I couldnt tell you what stone holders I used back then. The driver had a long neck for getting down in the cylinders. The cylinders and head are all one unit. Ill take your cautions on the used sioux equipment. I rarely by any power tools off ebay. Might just save up and buy fresh equipment. This tool addiction is expensive, damn.....Steve |

most stone holders have a hole in the top of them(drive end) I wonder what that hole is for :shock:
on a nother note, if you need to enlarge seats the wore out stone holders work great for that as they chatter away the seat faster than smooth cutting action.whooda thunk it...never try to cwnter a seat by pushing this way or that way on the stone,do not apply too much pressure, very light works best. keep the pilot oiled lightly and CLEAN EVERY TIME YOU PULL THE HOLDER OFF OF IT.DONT LET THE STONE GET OIL SATURATED.if you do..use some breakleen to clean the stones and spin dry :wink: .iVE NEVER HAD A STONE FAILURE FROM THIS. if the holder is wore out it may cause stone failure(explosion) especialy if you apply toomuch pressure while it's chattering. stones also need to be balanced :shock: make a light cut all the way down the side untill it runs true.if you swap it to another holder you may have to do it again so dont trim too much as the stone will get too small fast.dont cut aluminum with the stones :roll: if you do clean them . always clean the guide real good befor incerting the pilot on every guide when you get to it. I keep them all covered untill that need the pilot incerted then clean them again and the pilot too, the abrasive from the stones and the seats will embed into the soft bronze guides extreamly eazy and will eat the valve stems every time the valves go up and down....or side to side,,,in& out...move!!! it's amazing how much effed up good shit Ive seen from a "machieiest" that didnt know squat and knew how to spell.. :wink: if there is a tiny burr on the valve stem it will kill the guide. do not over oil the guides, if you do rinse them out with breakleen after assy( rinse out the oil in the ports), if it sits a while and the oil runs into the ports....breakleen it out, you do not want any oil interjected into the chambers....it's not a effing diesel. |

The beauty of the Sioux pilot system is that they have incremental sizes. Awesome if you are regrinding used heads w/ guides still in tolerance.
But if the guides are slightly worn and you run a cutter w/ wobbly pilot, I doubt you will have a concentric seating.
Sioux valve grinder are the best there are. NOne even come close to accuracy even w/ used valves. It has the best holding/chuck on the market.
Black/Decker type w/ removeable collets is fine if you are grinding new stem valves. But for used valve stems that just needed some touch-up, Sioux all the way. |

I just made another sioux and decker stone holder :P
sioux holder converted to 3/8 pilot and 5/8 hex drive.
That was a challenge this one, in order to get the height reasonable, I cut it in half and welded back together. It came out straight, probably luck. Only took a few hours. I should be doing other things, but I like playing with these for some reason.
Sioux pilots, yes best design.....but, you can also use a straight pilot, if it's good and snug, or take one of the 40$ stright tapered ones .001 too big and polish down the middle, and it'll work just like a sioux pilot, well, darn close. |

the beauty of the sue pilots is..they can bend and wear out just lke the others....and they also break. i wish they all used the same dam plot sizes and stone threa sizes.. iv never seen soux grinder that would cut concentrick. my snappoff does. but that all comes down to life. i dont paticularry like my snappon as far as using it, but the results are outstanding. wish i had a quickway that worked as good.or even a suioux. imho you need to check your pilots weekley depending on users and usage. you can get new pilots cheep on fleebay if you have the time to waite for your size. ive even made tooling out of guide pilots. |

First off... bump. What angle plate is needed for t1 heads?
And also, I need to buy a 45 degree carbide seat cutter. Like this, https://www.ebay.com/itm/284298529805?chn=ps&n...dQQAvD_BwE
Problem is, I can't find them with an 8mm pilot. Anyone know who makes them? |

type "8mm valve seat cutter" into the search bar.
right away I found a kit with 8mm pilot
Your add says the brand is Danish.
No idea about these inda mystery tools, but I do know how to use fleabay. |

Haha. Yeah idk why it didn't come up for me. The only difference is I put carbide in the search box. |

Wrt which system to buy & use I think the questions should be:
1. How many heads are you doing per year?
If you do 1 set a month you can live with a slower set up.
If you do 5 or more sets of heads per moths you need something that does its job in a fast and easy manner.
2. Which types of engines are you making?
If it is engines that "just" need to run decent and you are not chasing power & driveability (like many apparently are) you can live with a system that is not super precise, but on the other hand gets the job done at a reasonable quality.
For us the rating is about like this, - from an industrial point of view. Serdi, Newen, Goodson, Mira.
From a small shop mechanics point of view it would be something like Mira, New3acut, maybe Siux.
Personally I don´t like the stone grinding, at all. Too time consuming, and you have to dress the stone and recalibrate after about every seat, and even then its a challenge to get it good. I had one of those sets years back, but soon found out that I could get a better job done on a proper seat cutter, so I sold it and went with paying my way from it on a Serdi.
As Brian (I think) stated, the valve job is only as good as the guy that activates the handles is. a good machine can make a lousy job just as well as a lousy set up can make a good job if the operator knows what he´s doing and knows the tooling.
I remember an old farmer from my yuth who had an on Farmall tractor with about ½ turn slack in the steering. He row crop cleaned with it, no problem. Then one year he finally decided to retire it and buy a new tractor, - which naturally did not have any slack in the steering. That guy harvested half the field before he got used to a no slack steering. |

do not worry about angle plate for VJ,use those for serfacing as your not going to find a head will all the guides at the same angle...put the proper pilot in and the bubble level and just see. So, build a 2 way tilt float table, not hard to do. you will be a lot better offt. or is that a lot less offt. |

This thing is alive? :lol:
First - those cutters you are looking at are hand-cutters. You will not need an angle plate. Just flop the head on the table and cut.
YOu have to decide how much equipment you want to work on heads. That is not even a question - I just know I need them. Valve grinder and seat grinder. If you don't have these - you will be sending out your cash to someone else.
2nd - my jig is plenty. Fully Adjustable to any angle - I even use this jig to cut carburetors.

Quick question:
If I do a light bead blast on old valve seats will this help by allowing to present a surfaced seat, rather than working directly on the hardened surface of an non-bead-blasted seat?
I have a set of Neway Cutters.
I have some old heads I want to practice on to attempt 3 angle valve job.
I'm concerned that the old valve seats will be hardened from years of use.
These heads are for me to practice on. They are not crucial. |

Blasting won’t change the hardness at all, just cleaning it up, and get the carbon off. I would do it for sure just so you will be able to see what’s going on.
