Valve Seat Cutters

[Barry Townsend]

Can anyone tell me where to acquire a valve seat cutter - I've tried all the obvious places on the net with little success.

I can't justify spending a kings ransom on a tool I'll probably only use the once.

[Colin Wilks]

I went through the same process a while ago and decided it was more sense to pay a trusted engineering shop to do the work. Received wisdom if you want to do it yourself is Neway, which is quite an investment. 
I am sure somebody on here will have a recommendation for a shop in N Wales.

What size do you need Barry? I have a 30 mm one:


Neway, tungsten carbide 90 degrees.

I could lend it to you.
Photos if needed!

[Barry Townsend]

I agree Colin but on this occasion it would mean removing the engine and stripping etc for a relatively simple once in a blue moon job.
In typical Austin 7 fashion what started out a a simple decoke keeps growing by the day!

I need to cut my 1931 RN valve seats - valves measure about 26mm so yours would be ideal assuming the angle is correct.

Hi Barry 

I bought one similar to this  and it seemed to work OK. 

I had to make up a tube to convert the diameter of the mandrill.

Hi Howard
I'm glad you told me that because a few minutes before your email I'd ordered, with crossed fingers, the very same thing from eBay.

Assuming that they solve the immediate problem I wonder what other little delights my RN will throw at me.

What you ordered should work Barry. This is exactly what was in every "garage" in the fifties!
My offer still stands if needed to anybody on your side. It would be my modest protest against brexit...

[Barry Townsend]

Hi Renaud
Sincere thanks for your very kind offer.
Like most I hate to borrow tools for the obvious reasons but it was good to know that the 'Austin 7 Brotherhood' comes up with the goods again.

Best wishes to you and yours for Christmas and beyond

Blimey, it's all spend, spend on A7s these days! Mine have been " cut" with a piece of emery paper glued to the underside of my "penny on stick" valves ( 30mm valves with 30 degree seats altered on my Myford 7 lathe but used to be by holding a file on the valve seat zone). Stick valve/ emery disc in guide, attach rubber sucker mounted in electric drill and give it a wizz. Finish off with valve grinding paste and check the sealing with pencil marks on block valve seat. Anyone gringing yet?

I'm amazed you used the electricity...
