Where can I get a arbor and cutter for a drill that I can use to cut the throad diameter? the guy that did a couple valve jobs just left a 72degree inner cut to the stock port.. so I gotta remove a BUNCH of seat materiel there,and it is VERY tediuos to do by hand. so anybody know what I need exactly, and where I can get it? thanks


note; I am not trying to do my own valve jobs.. just want to be able to open the throat/venturi out with acutter and arbor than by hand. something near a 90degree cut.

 

Jordon go to your local shop and find out where they get theres. We get our stones and cutters from Goodmark up here. there are many places to get this stuff so check the local guys

 

Theproblem you may encounter is finding an arbor that fits into a drill press or hand drill, if that is what you are after. Most arbors/tool holders will be designed for use in a dedicated cyl. head machine.

 

I wouldn't even mind making something that will work.. local shop said there is no way a serdi or sunnen cutter would hold up with a drill or drill press.. said the guide can't center it well enough.. *shrug*

 

Thats good and truthfull advice the shop gave you...If you used the arbor as a pilot in the guide you will still have some problems due to guide wear..I would search for a head shop that will allow you to carefully check over the work..Preferably one that does a lot of stock and superstock work...If your sereous about doing your own work then you can find cheap sunnen or serdi equipment on the net for just under 8 grand..I know how hard it is to find a shop that does good work..Luckily i have a good friend that owna remanufacturing facility and lets me use his equipment and a head shop that is very **** about his work...

Maybe a bowl hogger on a drill press..With a custom made fixture it should work fine..I use a fixture i made on a 3/4" drill press to do my own top side head machining..Strapped some tungsten steel to the base and its pretty damned sturdy and checks out perfect every time..
