While spending a couple of days with my buddy flowing his heads he was telling me about some custom seat cutters he had. I have been using Neway cutters for the last five years or so and have been limited to 60-45-30 and 15 degree angles. Some of these heads really look like they needed a 70 degree bottom cut so I ordered a couple different 70 degree sizes, a 30, and a nice 15 for top angles. With the guides and needed tooling it came to slightly over 200.00 and a 3-4 week period to make up the kit. Can’t wait to try them out.

What brand are they PBR? I have been close to pulling the trigger on either an old Sioux stone grinder or a set of Neway cutters a couple of times but neither option is inexpensive. Care to share a link and what number cutters we need to handle valve seats in common small block and big block sizes?

I love my Neway cutters and hope to never touch a stone again. This guy is on eBay based in China. Very good email communication back and forth as I came up with what I wanted. Had a late January to mid February shipping date and I got it fedex today. I will try to post a link from my desktop later.

Cool thanks. Let us know how they do v/s the Neway stuff. I have seen the sets from India on ebay but did not want to buy them as I didn't know anyone with any experience with them. I even thought that if the India set cutters did not work well that they maybe could accept cutters for a Neway seat cutting head.
 
I cant believe anyone would want a grinder , or even think about it , no comparison !!
Maybe a lawn mower head ?!
 
Like Woody at Radar's shop says, "we don't machine heads with a rock"! (they have a Serdi) LOL
 
Curious what's needed to use these. I seem to remember, as a young lad, working with the machinist at the auto store worked at a sort of "slow drill press" looking thing that turned the carbide pretty slow. Could it be done by hand with a speed wrench?

Well, there was a time when most all reconditioned valve seats were done with a grinder. Some were still able to get pretty good results using them. Its kind of like bondo. In the wrong hands you can wind up with a mess for sure, but if used properly there is nothing wrong with it. That said the Neway multiple angles on one head cutters are looking pretty sweet.

Neway has a t handle that comes in their kits. I would assume something similar in PBR's new purchase. They also sell a motorized drive for them as well.

Ah, so with the "T" handle it's sort of like driving a tap?
 
My son uses a Serdi styles they are removable multi angle bits. He has up to 6 angle you can go to 7. Also he puts in an under cut.

I have the drive system for my Neway cutters but have been doing them by hand for years. A few turns by hand and proper fluid from Goodson and you are moving on. I am still kicking around buying this

Here's a link to the guy I dealt with and he has excellent reviews. He communicated great by email anytime I had a question or wanted pricing. Do your homework if and before you order as many of the kits are for many or different sized valve guides. I didn't want 5/16, 7/16, or 1/2 inch pilots so why but them. I didn't want cutters to do rototillers or go-carts so why buy them. I paid a little more by piece to get the ones I wanted without the fluff. Remember he's from India so don't expect IMEADIATE responses as it may be night in his area.

I used to work for dresser ind. , the pipeline engines compressors had poppit vales in disc shaped housings , with around 27-30 (cant remember for sure) , In each disc , had to grind those seats for more years than I want to remember , hated every minute of it , probly ground more than u guys have seen , altho they wern`t performance type stuff , some times 30-40 discs in a single compressor , 4 to 8 compressors on each engine , depending on how big it was .
They had v-16 and v-20 engines that were bigger than a lot of buildings , they were so big they couldn`t be shipped assembled , much less w/ the compressors bolted on the side of them. Best thing I ever did was get away from that place !
If I need any head work done , I have a friend that has a serdi machine -------------

I’m kinda stubborn about asking for help or favors sometimes to a fault but that’s me. I’ve never paid to wash, wax, detail, or change oil in any of my cars ever.(except if my sons needed the money). I’m kinda nutty.

I have zero valve work right now. The speedmaster heads flowed great on the intake side for Ethans heads and they lapped in nice on the ones I checked so far. I didn’t check the exhaust side on Ethans heads yet but the set I ported last year worked so good I was afraid changing it could mess it up. I may be awhile till I try them out.

I like stones, they're what i use.. but they sure are messy.

I did it like that for awhile and still have my equipment. My stone holder needs replaced but I hate doing it like that so hopefully I never touch that stuff again. That’s dirtier than porting aluminum heads. Notice I said aluminum not cast iron. Lol
