I was very critical to few of your old videos and repairs you have done. But this machine is amazing I can see how wrong I was and how great machinist you are. All the best !
@@PaulXchannel very interested! thank you for the reply, as a car builder and hobby machinist and now full time automotive machinist not to mention motor cycle lover, you gave me a bit of much needed inspiration in this covid mess! I appreciate it!
Very nice machine, would be interesting to see more details on the build, mainly the air locking spindle! This puts some of the store bough pro seat cutting benches to shame!
It's awesome that you added an air brake what an awesome machine. I wonder how much faster it would be on this machine compared to a milling machine? Good stuff I love your videos.
Amazing machine. I had a Serdi 3.0 and this is such a similar machine. Great build!!! Any chance of sharing how you made the spherical head? I am looking at making a machine like this myself.
Now valve seats are lowered, and valve stem might be to long to set proper valve clearance.. how do you fix this issue - would you grind valve stem to the length ? Great machine - you inspired me to make one...
@@PaulXchannel Ift there is a shim - ok, but like I said - there is no such option. What will you advice then? stem grinding, or replace a whole set of buckets??
@@PaulXchannel I have read some of the comments .. this video was made more for people like me . People in the trade doing this day in day out. I don’t do motocross bikes so no conflict but the development of a product like that blows my mind. I have parts designed and CNC made and that’s tough. To piece this together is like I said brilliant. Entirely and Absolutely !!!!! Your on another level ! I’m a fan ! Love the videos, the videography, the enthusiasm you have for your work. We all bow in your presence ! You def get a YOU DA MAN !
How are you checking heights? Do you have to remove your cutter, pilot, and spindle each time to check with a valve and dial indicator? I think this is the first time I've seen a pilot that spins in a guide vs. the cutter spinning on the pilot.
@@PaulXchannel So you're not checking to make sure that the each exhaust seat and intake seat height match? I didn't pay attention to the top of the cylinder head to see it it has rocker arms or overhead cams. If it's overhead cam what are you going to do to match installed heights? Just shim the springs and grind the tip of the valves? But aren't you running titanium valves? Then grinding the valve stem tips wouldn't be possible right?
This is a nice piece of design and engineering, I like the magnetic lock up (bit of a problem for ferrous heads)Many Serdi design cues used here though.
@@PaulXchannel how about original valve? Same treatment or not as titanium valve... Sometimes i was worndering after making valve seat angle cutting do we need to grind valve or not either titanium valve or original valve
Hi Paul. You are a very talented engineer. I really enjoyed your video. I think you are a great video editor too. I have a small question for you...What is the power /CFM of your vacuum pump you use to lock the boring head?
Thanks for your reply. I was referring to measuring the angle initially, to determine the correct cutter to use. Do Yamaha, Suzuki etc differ from KTM seat angles for example?
There is not much difference between manufacturers. The standard is 45 angle. The top is 30 angle. The inside is 60 angle. Then there are also 5 angles.
You did leakage test with vacuum, but in our countries guys usually do test with kerosene. Because it is very fluid or fluent. What is better in your opinion?
I think vacuum equipment is used in the factory. It's fast with the value on the display. Kerosene is used when there is no vacuum pump - it is also good. It just takes longer.
Ive cut seats like this on my mill and you need to put a sponge under the cutter to prevent chips from going down the guide to prevent galling with that rotating pilot.
So you are telling me that you designed and built this thing, including the air lock swivel tool holder? The R&D put into this machine must be enormous
I don't understand the function of the "adjuster nut for cutting". Shouldn't there be a spring inside to take the spindle back up again after cutting? Nicely made machine, though! ;)
everyone's an expert, don't listen to the doubters, you do great work, keep it up.
Thanks for watching.
Add the tools to your custom bench for lapping too! Then its complete hahaha
Great work!
Please never lapping titanium valves.
Thanks.
@@PaulXchannel I wasn't saying for the ones you just put in, but to make the tool set complete :)
Fantastic. Good work.
Wish i have such a good equipment ...
Paul, you are grate mechanic! Thanks for another one video!
Thanks for watching
I need this machine

Oh man. You just took custom machine building to a whole new level. That's inspiring !
Wow, very innovative design using the electromagnet brake and the air lock spindle. Very cool, thanks for the video :)
Thanks for watching
Beautifully made machine. Congratulations
If we lived in the same town, i would have so much work for you!!
Excellent machine . Any shop doing head work would want this right next to the flow bench. They always say the horse power is made in the heads.
Do you lap the valve after seat cut?
Looks a very well thought out machine. Do you sell these ?
Not. I only have one.
@@PaulXchannel you should think about marketing these there would be a market for them.
👍
Paul did you build this seat cutter
Yes
Did you make the bubble level holder?
Yes .
Video next weekend.

Thanks for watching.
Is there a valve seat pocket cutter?
Beautiful tool, a touch over the top but a thing of envy.👍
Insane! Absolutely insane.. and to say it's all hand made 👏
Thanks
The head is moving around while cutting...need something there.
Good invention
Very nice machine, would be interesting to see more details on the build, mainly the air locking spindle! This puts some of the store bough pro seat cutting benches to shame!
Thanks. I will show in future videos.
It's awesome that you added an air brake what an awesome machine. I wonder how much faster it would be on this machine compared to a milling machine? Good stuff I love your videos.
From where to buy it...🤔
Very slick setup! Can you use this to cut the seat completely out and replace them?
Working on it.

Very impressive! Love your work
Thank you very much
Man where did you get that air brake head?
Where did you get the round bubble level?

So like this tool will work on any kind of engine block to cut an reseat the valves
Now valve seats are lowered, and valve stem might be to long to set proper valve clearance.. how do you fix this issue - would you grind valve stem to the length ? Great machine - you inspired me to make one...
smaller size shim under buckets?
@@chem6269 Not every engine use such great invention like a shims :( I had this issue many times - last time with Ford's 2.0 Duratec... :(
smaller size shim

I cut the valve seat only minimally.
To make the right angles.

I think today most of the VGS machines are live pilot unlike the Sunnen VGS20 for instance.
Beautiful work as always, please keep up the good work.
Thanks
The air brake on the spindle is pretty cool... did you make it and is it ridged?
Not. It's just machined
Very impressive machine you built👍
Thanks
Are the pilots / arbors made of carbide ?
hardened steel and ground
It's really amazing you do it, a round of applause Master!!!!👏👏👏👏👏

I would like build a machine like this. Exists some way for get your help? Thanks.
pretty interesting.....i think they use a nearly identical machine for doing stereotactic craniotomies
Wow,what a piece of kit,top job as always,👍👍
I wants this machine. But where l contract.
This is a nice piece of design and engineering, I like the magnetic lock up (bit of a problem for ferrous heads)Many Serdi design cues used here though.
Thanks
Nice nice stuff man... u are a genious... with a lot of nice machines... u are good... damn good at what u do
Thank you very much
Hello sir how to grand this tool make avideo
If i may ask after valve seat cutting do we need to grind the valve again
Titanium valves must not be grinded due to the coating.
Therefore the machine must cut the valve seat accurately.
@@PaulXchannel how about original valve? Same treatment or not as titanium valve... Sometimes i was worndering after making valve seat angle cutting do we need to grind valve or not either titanium valve or original valve
A steel valves can be ground.
Especially after manual cutting.
High speed engines should not be done by hand.
@@PaulXchannel alright thanks for the info
Never lap a valve and seat.
good work man all the best to you
Thanks.
You too.
show, otima maquina , ela sera comercializada?
Hi Paul. You are a very talented engineer. I really enjoyed your video. I think you are a great video editor too. I have a small question for you...What is the power /CFM of your vacuum pump you use to lock the boring head?
Thanks.
8atm.
@@PaulXchannel Do you happen to know the HP of the electric motor that drives the pump?
No
I really like your machine, very good idea and job. Thanks for show us.
Thanks for watching
Amazing and correct way of working
Hi Paul Great work. How do you measure the valve seat angles?
Thanks.
The cutting insert has exact angles at the factory.
Thanks for your reply. I was referring to measuring the angle initially, to determine the correct cutter to use. Do Yamaha, Suzuki etc differ from KTM seat angles for example?
There is not much difference between manufacturers.
The standard is 45 angle.
The top is 30 angle.
The inside is 60 angle.
Then there are also 5 angles.
@@PaulXchannel Thanks 👍
@@PaulXchannel pros and cons between 3 and 5 angle cuts? Can one say one is better than the other?
Que máquina!!!! Felicitaciones
Hey Paul, amazing job! Where did you get the seal adapter for your vacuum pump to test the manifold?
Thanks.

how do you keep the same seat depth please
Cut only to clean
Donde la puedo conseguir
Great! Cool machine! Done accurate. Curious, how it works - airlock spindle bearing?
Very simply .
I will show in future videos.
Qual valor de uma máquina dessa
Without lapping ???
Titanium valves must not be lapped !!!
During cutting, there is no visible indicator showing the deviation of the spindle from the cutting force. The console is in action.
Can we buy it ???
Great job where I can buy your seat valve machine?
Thanks.
Not for sale.
Wow۔۔i love it my future wish this machine
Where can I found the air spindle mechanism?
I invented this system myself.
I will show in future videos.
Gostaria de saber se vcs enviam para o Brasil ?? E qual valor da máquina ??
What engine did that head come from? It doesn’t look like it would be on car engine, or an airplane engine. Just curious.
Cylinder head from a Ktm 450 sx-f motorcycle.
Paul X Duh! Intake on one side, and exhaust on the other! Thanks for the reply!
exactly

Plz reply
Thanks
great, greetings from Indonesia
Everything is so cool and solid and technological but... To affort that you need to do A LOT of valves repairing ☺️

how can i buy air valve seat
apparently just produce
How much whole machine?
So this video shows how to make a bigger valve?

Not for sale.
Thanks for watching.
Where I can buy it? And how much is price?
凄い❗装置も全部、自分で作ったんですか。
Really nice machine, great work!
Thanks
Ive cut seats like this on my mill and you need to put a sponge under the cutter to prevent chips from going down the guide to prevent galling with that rotating pilot.
Does it really need this level of complexity ? There's already a valve guide. Why not use that ?
The accuracy of the valve seat machining is very important.
Man that is awesome! What is that air locking swivel called? First time I’ve ever seen one. You do great machine work 👍
Thanks.
I will show in future videos.
All most the same as a series 100 or 80.i like the one you use what the price on it
It's not bought.

Not lapping?
Titanium valves don't need lapping
titanium valves should not be lapped. Sorry for my bad english...
Some machines have coated valves that must not be lapped and just rely on good seats.
If the valve face and the valve seat are cut correctly no lapping is necessary.
I want this machine plz reply
I don't understand the function of the "adjuster nut for cutting". Shouldn't there be a spring inside to take the spindle back up again after cutting? Nicely made machine, though! ;)

Is there any chance to get your blueprints for this valve cutting machine? I want to Make one myself 😁
The machine is made of old parts.
You just have to improvise .
