What is the best adhesive to attach a felt
backing piece?My project steel is rock maple stained with Minwax oil stain and I will be rubbing on many coats of glossy tung oil as the final finish.
I assume that the area in back where the felt will be glued should*not* have the tung oil finish applied as I would guess it might interfere with the adhesive sticking well?Is this correct?
I chose the tung oil as no matter how carefully I vacuum and clean up my work area,I still manage to pick up a few tiny but very aggravating(!) dust particles whenever I spray on any kind of finish coat.
I can control dust better,I find,with hand applied (as opposed to sprayed on) finishes.I assume this is due to the force of the spray causing dust particle to rise up and land on the finish.
Of course I need an adhesive that won't damage the oil based stain I used.
I could skip using the felt,but the wood is a two piece join and I was not 100% successful in completely hiding the seam line with filler.A hair thin,darker line in the wood remains at the joint all along the seam.
Of course the felt would hide this seam line as well as helping to prevent the instrument from sliding off my kness,getting scratched,etc.
Thanks,
Malcolm |

Hard to get any adhesive to stick to an oil finish so keeping it off the area to be felted will be important and may be impossible.
Oil tends to soak into the grain and could permeate all around the edges of the felt area which is exactly what you don't want as it will cause the edges of the felt to lift.
One suggestion is to finish the part of the guitar that is to be felted with a couple coats of polyurethane before you oil.Then you can have at it with the oil and clean off the polyurethaned part with some lacquer thinner when your done.
I would experiment with contact cement or Gorilla (polyurethane) Glue. These will stick to sanded polyurethane.
If you use Gorilla glue it will foam up some when it dries so use it sparingly and expect some scraping type cleanup around the edges.I'd apply the Gorilla glue to the guitar in a very thin coat so as not to soak through the felt.

I havent used felt because finding a correct adhesive Was hard.
instead I used an old hard cover book cover.
first I made sure the book had no value. then I simply cut the cover to the shape I wanted.
make sure to cut it oversized first. that way you can use the extra width of outer cover to fold over the newly cut edges.
I used a simple adhesive to hold the trimmed edges in place.
I also used this method to slip guard the back of the neck. I found matching books at a thrift store.
then it is a simple matter of finding appropriate looking flat head screws to attach it to the back of the lap steel.
with the right book cover it will look vintage/awesome.
and it slippage wise, it works great.[This message was edited by Randy Reeves on 11 January 2006 at 06:15 AM.] |

A piece of luggage linen is cool. Like an old yard sale suitcase with busted latches. or a piece of tweed. I've done this over bare wood, with simple elmers white glue. then finsih with lacquer right over it.
However, oil finish saturates the wood as someone mentioned above. forget trying to have anytype of glue stick to it.
good luck. |

| Give the tung oil about a month to dry and then go over the back of the guitar with alcohol or acetone and it should stick ok. |
