@Eshmiel the good news is that using a chisel to do paring cuts it actually quite effective without totally ruining the edge or tearing out any wood, turns out a heat gun is also my best friend, just hold it over the patch of goop and after about 30 seconds it becomes soft enough for the chisel to make light(ish) work of it, fortunately most of the blobs are big enough for the heat to not damage the wood around it. It also seems the blob I started on was one of the hardest of the lot. After an hour or so I'm nearing the half way mark, hopefully once i've got it to just the most stubborn bits a quick pass with a sander would be enough to finish it off. Sadly, no cranked chisel, but I may have to invest in a couple, I'm sure it's a tool that will have more uses than one would initially think so thanks for the suggestion.
@Morag Jones paint scraper would probably work too but mine has been AWOL for a month or so, have a horrible feeling it's under some floorboards. Another thing to invest in!
@Mick p, good to hear from you, hope you're well too. The lathe still runs beautifully and has seen plenty of use, thanks again. Things have been a bit up and down the last year or so, the black suit has made some unwelcome appearances and I was out of action most of January with pneumonia, all on the mend now thankfully. I was planning on getting a couple of bowls out of this board and then seeing where the rest may end up. Half the problem is there's a huge roundover along 3 edges so it doesn't lend itself well as square timber but I'm sure I'll find a good project or two for it. That's a lovely piece you've made there, I really should do more square bowls as they do look fantastic when done well.
