[QUOTE="swampratt, post: 3107609, member: 15054"] I did not measure I drew lines on wood but those were useless. I set the teflon block on the wood with 1 screw in it so I could change the angle by pivoting it. I looked at the disc on the dremel cutter and lined up the valve seat on that and stuck another screw through the teflon into the wood to secure it. I then took a test valve and seen if it was on the money. Now the seating area of a used valve will be sunk.. and if you watch that video above and forward to 1:30 seconds into the video you can see where his valve was being surfaced on the outside edge and inside edge of the seating area at the same time. During the initial hit of the grinding disc. That would put you on the money as to being square with the seat. Or darn close and close enough to work. That is the way my valves acted when I began resurfacing them on this crude tool. I ground them all and lapped 2 valves in so far and it looks great. Only issue is the small diameter disc will only allow my teflon block to do the 1.5" or 1.60" valves in the current screwed down position.. the 1.94" intake valves I will need to move the block and readjust. But those intake valves are not pitted and will lap in as is. No grinding needed. [/QUOTE]
