Friend of mine gave me old black and decker vibro centric valve seat grinder. I found 45° grinding stone but that's about it. Didn't see 30° and 60° stones and 7mm pilot for it. He also gave me a valve refacer that I will pick up this weekend.

Check with Larry cav

These guys list black and decker,not sure what parts they stock but they might point you in right direction www.rtsalesinc.com/web_quotes_english/Va..._Equipment/index.htm

No eBay APP ID and/or Cert ID defined in Kunena configuration
Not sure if theyre what youre looking for but theyre listed under black and decker anyway
Oh hell says theyre sold,maybe they can find you some more though

check with,

www.barksequipment.com/

call em they can get you anything you want.

do you have a stone dresser?

if so you dress your stones to whatever angle you want (after you square it up) if you can't find the right angle.

also might check goodson

www.goodson.com/

you need to know the top size of the pilot to fit your stone holders.

i had an old black and decker like that,i had to cut the end of an allen head bolt that had the right hex and weld it on the stone holder to rebuild it because it was all wallowed out.

but then i got sioux valve grinding equipment and haven't looked back ,until now hehe.

hth,

Try here at Cylinder Head Supply:
www.cylinderheadsupply.com/nsearch.html?...pply.com%2Finfo.html

If what you want is not shown, I'd email or call, as he can get it for you.

You'll want more than one 7mm pilot. Get .274, .275 & .276.

Some suggestions, do with this as you please:

Stay away from expandable pilots.

Use a bounce spring.

Use Ruby stones.

Face every stone, every time you change one.

Don't even think about putting a top cut above the 45 using the grinder unless you're really practiced with it. 35 or 38 is better than 30.

Best results are obtained by cutting the top first. Get the top cut straight. Cut the inside, then use the 45 to locate the seat on the valve face properly. Push it out there. You're wasting your time and loosing flow area when you locate the seat in the middle of the valve.

Exhaust seats are always way low on the face. Push them out.

Now you need a way to tip stems and measure installed heights. You should measure before you even cut the seats so you see what you're up against. 1.475" is your target for mid shim range.

that is solid advice that would take most folks years to figure out,if you did it every day...

thanks for just layin it out there larry.

if you have any desire to ever do your own valve job print out what larry just wrote.

Thank you everyone.
I am having problems with sprint wireless hotspot lately and can barely look thru web. I love living in the rural except this. Cable and DSL come short to turn into the road I live off. Not enough houses for them to run the cable according to them.

Anyway I really thank you all for information. I need to check out those places when I go to "city" where I can get better and faster connection on business trip this week. I will have to mess with it and learn how to use this thing.
He also gave me this thing. Coolant nozzle is missing so I need to make one up. other than that looks like it is good shape. I need to learn how to use this thing too.

Looks like your missing coolant line is standard "loc-line". The stuff is common on most machine tools that need coolant. www.loc-line.com/quarter-inch.php I would guess that is the quarter inch size that I linked.

I cut and pasted the NC vendor list from their website for you. I would bet you could pick some up at Grainger if you are in the city on your business trip.

Cool. Thank you.
Looks like something like this will work.
"40473 1/4" Mixed Element Kit $18.20". I will need elbow, straight, elbow and nozzle.
I will check at Dillon or Grainger. they are not too far.

You might have to fiddle with the chuck a bit to get the valve to spin straight. Make sure you face the stone on that as well.

A spray bottle with water will work as a temporary setup. Go easy....
