    I started with 3/8 inch (9.5 mm) plywood that was left over from construction projects. This was laminated in three layers for a thickness of 1 1/8 inch (28.6 mm). A rough shape was cutout with a bosch jigsaw and then rasp and file were used; there was no real plan.<br><br>Sandpaper in grits of 60, 120, 500 and 1200 were used. Learned a new trick - the paper backing on the sandpaper kept ripping so I put duct tape on the paper and this solved the problem. Next tried the chrome polish and this really smoothed things out.<br><br>A thin coat of resin glue was applied as a sealer and when this cured a red acrylic ceramic paint was used. After this several more coats of resin glue were applied with a quick steel wool rub down between each.<br><br>By this time the slingshot had a real nice shine and I was pretty happy. Decided to finish it with some Bar Keeper's Friend (a stainless steel polish) and then some toothpaste to smooth the resin and give it a nice shine. And also as a bit of an experiment. This is where everything went to shit.<br><br>The resin started to come off like rubber cement. Not sure if there was a chemical reaction with the bar keepers friend but this was really surprising since resin glue is basically epoxy.<br><br>Really unhappy with this. Guess I will band it up and see how it shoots.<br><br><a href="http://m.flickr.com/photos/[email protected]/7300433810/lightbox/" class="postlink" target="_blank" rel="nofollow">photo 1</a><br><br><a href="http://m.flickr.com/photos/[email protected]/7300413394/lightbox/" class="postlink" target="_blank" rel="nofollow">photo 2</a>

    You forgot to upload an image.<br>When you write a message, look for the green icon which reads 'Image' when you hover the mouse pointer. enter the image link that you have uploaded on a image hosting site. Or, if you want to upload directly click on the similar icon with floppy image.

    Sorry about the pics. I am having trouble with Picasa.<br><br>I worked the slingshot back down and repainted. Got one coat of resin glue on it. Either I didn't wait long enough for it to cure or maybe it was the humidity. Used three coats on a hammer handle a few weeks ago and the stuff setup like a rock.<br><br>I will post photos as I work on it.

    Just sand it off and try again until you get it right. You have it cut out and shaped, so don't worry about it. Just take your time until you get it. I am curious why you would apply a glue finish and then put something else, such as the paint, over it. I mean the glue finish is used as a clear protective coat for the stain, paint, etc. used right? I don't think it's necessary, but I don't know much about it. I would wait until you have it coated the way you want it and then worry about the clear. <br><br>In any case, no need to get frustrated. Looks like you did a good job with the woodwork. Worst case scenario, just sand and polish the wood as much as possible and leave it that way. Should look and work just fine.

    Cbsmith,<br>the paint I used is for ceramics and is designed for hard surfaces. The first coat of finish was just to put the paint on and allowed me to keep it thin and see-through. My frustration was actually caused by three things: this finish, a crack in the one-tool fork I was carving and none of my posted photos were working. Decided to change pace and make a few knives since my luck with slingshots was so bad.

    I see. Still though, the slingshot looked good to me. I was just saying don't worry too much about the finish.

    It won't let me see them. Is there a reason you always post links instead of the actual pictures?
