I need to brighten/ bleach my pine picnic table 2"x12"x8' boards that have the blackened water marks, etc. before I finish with Spar. Its great to see after its done so. I have liquid pool chlorine, which does a great job of whitening, but may have its own drawbacks (maybe not), but someone mentioned oxalic acid instead. The problem with pool chlorine is that the poly doesn't stick after, but I've only ever done it once or so to know whatever I did or didn't do didn't adequately rid/neutralize it. Again someone mentioned sanding. I could work chlorine in earlier to the overall re&re process this time. I probably did nothing or a light water rinse before, &/or maybe a light sand. Again any further comments about neutralizing for either the chlorine or oxalic acid, or any other product. Oh ya, and where do I get it in Toronto? Not LV, CT, HH, or HD!
Has another used or will recommend buying the accessories that you can buy from Lee Valley for sharpening a cabinet scraper? I think I can sharpen and flatten the scraper alright without extra tools. Just need a good flat file after it is normal and true then take a few final level swipes. But I have yet to get a piece of (round) metal stock of hardness greater than the scraper for putting the crucial finish on it, and you just can't find something anywhere around the whole house can you. There are two (2) items I think might do the job, a piston wrist pin or a valve lifer, form an automobile, but don't know if either is a good fit. To get the hook I get the feeling (experimenting with a kitchen knife sharpening tool) that a load of exertion is required, and then there is the skill level too. I'm no craftsman but for getting rid of bondo on a door jamb there is no other tool, and the list goes on. But I wish I could get mine working right; barely useable as a paper weight when I am done with it currently. So here are the LV products. Are they good investments? About $37 for a sharpener! Or should I get to the auto rebuilders with a fiver?
BTW Is the simple act of posting here in NGs lately causing my junk mail quantity to increase? You can e-mail me an answer if you wish!?
