Lacquer thinner could most likely strip off all the lacquer, and while pretty toxic it would still beat sanding if you have good ventilation and a respirator with carbon filters. You would still have to scuff up the finish, but it would be much, much less sanding.

Someone may know better than i though.

I tryed thinner the first time round made everything white and messy im not sure why but im peeved at my self for making the same mistake twice im wondering if the lacqer dont eat the poly wether it would be better to just do another coat of lacqer

These things happen John, i feel for you. I was cutting lumber this weekend to start a build on an entry bench for the breezeway at our house. I was using the dimensions off of a piece the wife found in a catalog. I had just finished jointing planing and cutting them all to size when i realized that i had made the width of the bench 22” not 42”, a typo in drawing my sketch. A 22” bench … cmon man! Luckily i had underbought lumber and i could use the messed up pieces for leg glue ups. Back to the lumberyard though.

@chrisstef – That’s a chair, not a bench!

@John – Recipe for success: take a nap, watch tv for 30 minutes to sufficiently wake up. If you fall asleep again, it means that it was a good thing you didn’t work out in the shop. Repeat process until fully awake. Next, set up a tool, like a router table, that is marginally related to what you’re working on. Next, cut some wood just because you feel like it. BEHOLD the POWER!

Congratulations, you have completed your woodworking calisthenics.

Finally, Make a few pencil marks, table saw rips, and passes on a router table before it gets dark out. Complain at the lack of light this time of day. Retire back to the couch.

Congratulations, you’ve accomplished something!

AKA, how yesterday went for me.
