Experiences hammer veenering?
I have made a solemn oath: I can buy blades and "wear related" items,
jig supplies, fastening hardware and wood for the shop, but nothing else. Even planes are out (that is a toughie, though if I stumble across a bunch of excellent quality cheap molding planes I WILL sin). OK, I am not 100% successful at keeping it (and man does those HVLP threads make me tempted) but I am working hard to keeping it. But, I really would like to try a little veneering and -- if that works -- start making my own veneer (for my own uses, not commercially). I don't own a veneer press, don't own a vacuum press. Reading a very old article by Tage Frid, he makes hammer veneering sound pretty doable. However, a later article by Ian Kirby says it is pretty hard to do. Has anyone had any experience doing this that they would be willing to share? Particularly on success rate, number of tries to "get it right" and success with thick veneers of the sort you tend to get off of a bandsaw/planer set-up. Paul K |

Tried this, very tricky. Requires a real good touch, heat-press-move,
heat-press-move, give up. Get a piece of veneer, real veneer, not the stuff from Woodcraft, its too flat. Flatten it, takes several days, instructions on net. Spread glue, let dry, set iron on pretty warm, lay down veneer, heat-press-move, watch veneer buckle, heat-press-move, cuss, give up. Plan B. Flatten 2 pieces veneer, one for each side. Get oversize MDF at the Big Orange store. Put yellow glue on both sides. Put veneer on both sides about an inch form one edge. Put garbage bag over veneer. put MDF over garbage bag. Clamp well. come back tomorrow. Unclamp, trim to suit. Works for me. Be sure finish is water resistant or the drool will leave spots. Paul Kierstead wrote in message rs.com...

A very intentional loophole. After making some rudimentry jigs and other things instead of buying them, I realized it was great experience and that they worked the way *I* wanted them to. And were cheaper on top of that. So making a veneer press is very much in the picture. *However* my longer range intention is to veneer large surfaces; with a press I am limited and my shop can only accomodate so large of a press. With hammer veneering, Tage Frid claims you can "veneer the world". Although I have have a wood threader, so I could make a veneer press with very minimal investment... |

Interesting you should ask. I read the Frid article and it seemed so easy.
I was making a dining room table.....My wife agreed to help me with my first hammer veneering project. That was 25 years ago. It became known as our first "divorce". Talk about mess...hot (burned) hide glue, burned fingers, wrinkled veneer, terrible seams and lots of yelling. We are still together but....I have taken a solemn pledge....no more hammer veneering. The table is still in daily use; with its cherry plywood top. Anyone want a slightly used veneer hammer? Dave "Kim Whitmyre" wrote in message ... In article pmkierst-079689.02080109032004 @nntp.bloor.is.net.cable.rogers.com, says... Has anyone had any experience doing this that they would be willing to share?

But let me suggest "Making Classic English Furniture," by Paul Richardson, Guild of MasterCraftsman Publishers. He has an excellent section of the technique of veneering: demystifies it very well. He uses hide glue, which eliminates most of the problems relating to finishing the project. Kim |

Nothing that I read seems to get around to mentioning that the hide glue is quite *HOT*. Ran up some water to that temp, and it is pretty hot. Anyone want a slightly used veneer hammer? Naw, I am gonna make my own Paul K |

Will be posting more on all that I guess. But would to hear your experiences. Well I took the class. I am going to give a very short description of what I found out because the instructor will be giving the details in a Fine Woodworking Master Class to be published in the next issue or so. We spent some time discussing the various options for materials while we waited for the glue to heat up. We used hide glue on mahogany veneer applied to MDF. We practiced cutting the veneer and then joining pieces using a couple of different methods. The following is a summary of the major points Hide Glue - You want to use this if your project will allow. It gives you a reasonable working time and is reversible and repairable. The are several different kinds of hide glue. The stuff sold in many stores is a pearl type which takes forever to dissolve and heat and probably has unknown characteristics. The characteristics of the hide can be controlled when they make it. Get a 192 type ground hide glue if you can find it. Places that specialize in materials for making guitars will be your best source. Veneer Saw - Used to trim the veneer. They cost about $20 - $30 and will probably need a little tuning up before use. Remove any burrs on the base ect. When you cut with the saw you will probably use some kind of straightedge. A 2X4 with a jointed edge will give you a large flat surface that the back of the veneer saw can index on to give you a good straight 90 degree cut. Veneer Hammer - Look like a window squeegee. Used to press and scrap the veneer to get the glue flat, air bubbles out and the veneer edges tightly joined (if you are matching seams). You can buy one or you can look at a picture of one get yourself a piece of hardwood a large dowel for the handle(sometime omitted) and a small piece of 1/8 - 1/4 inch brass to inlay and epoxy on the edge to a grove cut in the hardwood edge. Glue pot - Heats the hide glue and keeps it a proper temperature. You can use double boilers or any thing else you can dream up to accomplish the same but it's not a good idea to have the glue overheat (or not be hot enough) so use a thermometer if you don't use a glue pot, be careful. Hand plane with a serrated blade or rough sandpaper - Used to prepare the base material before gluing. They make a specialty hand plane if you can find one but sandpaper will work fine. Rough up the surface and clean the sandpaper dust off. Masking tape and veneer tape - Use to tape together any joined pieces prior to applying the veneer to the base. This should be covered in the FWW article Card Scraper - Used to scrape clean the veneer top after the glue has set. Common house iron - Not a good idea to use your spouse's good one. Get a used one. Used with a wet rag between the iron and veneer to reheat and loosen veneer to correct any voids, glue pocket etc. In fact to whole piece of veneer can be removed if necessary. Good idea to practice this before you really do it to a good piece. Basic rules 1. Remember to apply glue to the base and to both side of the veneer. The top will have the glue "Squeezed" off when using the veneer hammer. By applying to both side of the veneer you will minimize any curling effect caused if you applied glue to one side only. 2. Be sure to keep working the veneer hammer to flatten any glue pocket and air bubbles. You will know when the glue starts to set up as the veneer piece will stop moving on the base and the glue on top will start to ball up and look like it came out of your nose. 3. The edges are the hardest part. Make sure all the edges are "squeezed" flat and are completely glued all around. Be careful as it is easy to crack the edge of any vaneer overlaping the base. |

Really appreciate the report. Quite helpful and will be looking towards the article. Nice to work with someone "respected". Veneer Saw - Used to trim the veneer. They cost about $20 - $30 and will probably need a little tuning up before use. Remove any burrs on the base ect. When you cut with the saw you will probably use some kind of straightedge. A 2X4 with a jointed edge will give you a large flat surface that the back of the veneer saw can index on to give you a good straight 90 degree cut. I bought one for C$13. I got about that much worth of saw; needed quite a bit of work, and needs a little more, but does the trick OK now. Veneer Hammer - Look like a window squeegee. Used to press and scrap the veneer to get the glue flat, air bubbles out and the veneer edges tightly joined (if you are matching seams). You can buy one or you can look at a picture of one get yourself a piece of hardwood a large dowel for the handle(sometime omitted) and a small piece of 1/8 - 1/4 inch brass to inlay and epoxy on the edge to a grove cut in the hardwood edge. Heh, in the meantime I went off and made one. I used 1/8" aluminum. Pretty rough, but should do the job: http://homepage.mac.com/paulkierstea...eer_hammer.jpg Glue pot - Heats the hide glue and keeps it a proper temperature. You can use double boilers or any thing else you can dream up to accomplish the same but it's not a good idea to have the glue overheat (or not be hot enough) so use a thermometer if you don't use a glue pot, be careful. I have been using a "Hot Pot" (C$20 at WalMart) with a candy thermometer. Seems to work well, so long as you get the water in it hot _first_, otherwise I think the heating element in the bottom would overheat the glue. I just have the glue in a mason jar. Hand plane with a serrated blade or rough sandpaper - Used to prepare the base material before gluing. They make a specialty hand plane if you can find one but sandpaper will work fine. Rough up the surface and clean the sandpaper dust off. Good tip. On my couple of trial runs, I didn't rough it up. I think this might be especially important on something like MDF which is so smooth to start. Common house iron - Not a good idea to use your spouse's good one. Get a used one. Used with a wet rag between the iron and veneer to reheat and loosen veneer to correct any voids, glue pocket etc. In fact to whole piece of veneer can be removed if necessary. Good idea to practice this before you really do it to a good piece. I am using the one I use to wax my skis... 3. The edges are the hardest part. Make sure all the edges are "squeezed" flat and are completely glued all around. Be careful as it is easy to crack the edge of any vaneer overlaping the base. I'll say. In my two trial runs, I had the hardest time with the edges. How well did the MDF work? Did it suck up glue like crazy? My first two tries varied...first one was one some very crappy softwood plywood. It telegraphed through. The second was on a scrap of baltic birch ply; no telegraphing in that case. But I have been eyeing some MDF... Thanks for the update, much appreciated. |

The edges of the MDF can suck up a lot of glue. So here's what you can do to help that situation. Depending on your brand of Hide Glue mix up a batch with twice as much water. Normal - 1 cup Ground Hide glue - 2 Cups water Wash Coat - 1 cup Ground Hide Glue - 4 Cups Water Apply this wash coat to the MDF and let it dry. If you are doing the edges you may have to try this more then once. Using "real" wood as an edging material on MDF is highly recommended over veneering the edges. Veneer is thin so defects will telegraph through. You could try applying multiple layers of Veneer. If you do treat it like you were making normal plywood and alternate your "grain" direction. If the base is really bad it will eventually telegraph through so use a good stable base. |

ER doc posted about the Rival Hot Pot Express a few years ago that has
a dial for maintaining heat at less than max. Mine was at a drug store for $15.00USD.

That is pretty much what I am using. However, the elemen is on the bottom; this means until the water bath gets up to temp, the bottom element will be quite hot, running the risk of overheating the bottom of the glue container. So I just let the water get to temp first and then the element runs in very short cycles. |

Thanks for the very valuable tip; filed away. I would generally always lean towards solid wood edging anyway, but just-in-case that is pretty handy to know. |
