Goodson Tech Bulletin Board

Hi Jim. Read your reply to post on 10/03/07. Regards bridgeport type machine use (R8). If the valve seat has to be alligned as critical as you stated why do I need a pilot at all? I could make a rigid tool holder to fit R8 spindle and use your 3D tooling. I use rigid tooling and time consuming allignment to install various size valve seats. I’m looking to speed up the process. The problem is that the allignment is too time consuming. It would seem that ball head drive should be somewhat forgiving?

Thank You – Ben

I recently purchased a used Sunnen VGS 20. It has the early style seat cutters. I would like to upgrade to a better three angle type setup…the main reason for this is I have alot of sioux pilots with the .385 top and this machine only came with five sunnen sized pilots. I dont want to have to buy a bunch more pilots. Or is it a bad idea to use expandable pilots for this application? What do you suggest a 3dfastcut system? What all would I need to upgrade?

I have been using your 3-d system on my bridgeport for about six years and I am still trying to get the concentricity perfect on all my seats. I would like to know if carbide pilots would make it worth the cost of replacing all of mine? Also would the harley head plate and tilt fixture you sell lock up solid enough with the single handle lock? With the plate I use now I have to double clamp it and use a machinist jack to secure it enough to get a true seat. Would a airfloat table work on the bridgeport and are they available. Thanks Gary at Universal Machine Shop Inc.

Who can I contact for parts for a Van Norman 944 boring bar? These are parts for the bar itself and not covered by the accessories that Goodson carries.
Thanks

I left a question a week ago and still did not receive an answer. It was concerning your equipment and tooling Does anyone there have an answer?

Are the economy bore gauges you sell accurate enough for engine rebuilding? I have to rebuild a tractor engine but dont want to spend the money to buy a sunnen right know. Also how do you set the economy bore gauges?

Thank Rick

I’m in the market for a new seat and guide machine. My old neway and Serdi 2000 just isn’t cutting it. I need to keep concentricity to .001 and replace seats and guides. I do mostly motocross dirt bikes and some road race engines with titamium valves and small guides. I would like to stay around 26K. I Didn’t go to the PRI show and I’m not sure what the current options are on these machines.

Just recently purchased this machine (super deal) and I’m wondering if anyone offers a video on valve and seat grinding.
Thanks

I have KO Lee stone dresser equipment cannot find a 1/4" diamond dresser with 20NC thread.
Can you help?

Are there any makers of Valve Seat Stones that will work for older model KO Lee equipment?
