In this episode of Tech Lab Tuesday, Goodson's own Dave Monyhan talks about lapping as in Valve Lapping. Not only does he explain how lapping works and why you would want to lap your valves, he demonstrates several of the lapping tools available.

An old timer (LOL now I'm one) showed me many years ago to use blue chalk on the valve face to check the seating of the valve after you lapped it. Rather than Diecom. Great video love your products. I have been a customer for decades.

Not to be confused with Lap Dancing.

I've been wanting to upgrade to an electric or pneumatic tool but I'm curious how you can even hear or feel when the process is working over all the noise and oscillation from the tools?

@GoodsonShopSupplies 2 года назад

your results are determined by sight and not really in feel or hearing. Even with the air tool I can still feel the grit working into the seat to mate the valve face to that valve seat. Your eyes and measuring tools are your final confirmation on whether you have achieved the proper lapping result.

I know I have a choice, but what if you don’t know what you want? After watching this video 2 weeks ago I went to your website and sent a request using your Contact Goodson link and still have not heard back. I purchased the 400 grit VLC only because I din’t know which grit to choose (in the middle) and because Goodson didn’t return my inquiry. I have never lapped valves before so I have no idea. In fact, I have never rebuilt an engine before. That said I am now rebuilding my 1987 560SL and I’m using the old valves. The valves look great to me (I have videos uploaded if interested). Can you please describe the different VLC grits & their uses please?

Hey Tony! Sorry about no one getting back to you. We had some technical issues with our online forms so they weren't sending the messages to us. I will get your question to one of the techs and we'll post the answer here for you (and everyone else).

@@GoodsonShopSupplies I never heard back so I decided to do a video comparing top brand lapping compounds and Goodson won! I test the results using a DIY vacuum tester I made. Here’s the video. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-2S8I5tb0TGE.html

You will never be able to lap valves very well with the wooden handle that fat , put it in the lathe and slim it down alot to a concave shape , this will keep your hands in the correct place and rotate the valve at a better speed .
