Help in removing playing surface. I have a pot call and want to replace playing surface without damaging call. Rather ask for help vs jumping in. Thanks
I use a hot air gun like for wallpaper use-heat the surface avoiding the wood (will scorch) until the liquid nails or goop loosens then pop it of by pressing the sound board off first then the surface with a striker tip from the bottom sound hole.
I attach my surfaces with silicon. So, don't laugh or kill me... but I use a hammer to remove mine if need be. I just pull the pieces out and then scrape all the silicone off and replace with another one.
If the surface is glass/crystal I usually take a hammer, break it out the best I can and then cut it out or press a chisel onto the top edge (avoiding the pot) and break it up small enough that I can cut or scrap the rest off.
If it is aluminum I put it in the oven as low as the oven will go for about 10 minutes and press it out with a dowel from the back through the holes. You will usually have to take the soundboard out also and let it press against the surface and push both of them out. I work my way around using all of the soundholes.
I have also drilled a couple of holes in the aluminum around the edge and heated the pot. Then I took a piece of metal clothes hanger bent on the end and stuck it under the aluminum and pulled it out from the top saving the soundboard.
However you get it out, I have found that it is very important to remove all of the old adhesive for both the pot and the soundboard. If done well the call should sound the same as it did the first time you made it.
Thanks so much guys. I will try the hot air method. This is a well made call and I 'am guessing goop is what was used.
If you use the oven method as Andy told you about...WARNING pot is hot when you pull it out! Trust me on this one use a hot pad
So it's not your pot? I wouldn't risk it since you said it was well made.
I use a embossing gun found in the scrapbooking supplies at Michael's or Hobby Lobby. They are like a hair dryer with higher heat and lower airflow (not as intense as the one mentioned in the first reply). I have never had the wood scorched, but I have warmed my fingers beyond a comfortable level. ;D
After I remove the damaged surface, I use a round sanding block that I make on the lathe. Turn a scrap blank of wood so that it is the same outer diameter as the inner diameter of your call surface "shelf". By that, I mean that once you turn the sanding block, it should fit nicely inside the rim of your call, just like your surface material. I use a pot call blank out of a less expensive wood. Once you get the diameter right, adhere a piece of 120 grit sandpaper to the surface of your sanding block with spray adhesive (I use 3M and am still on my first can). I rough cut a piece larger than my sanding block and trim it to size on the sanding block once the adhesive is dry. The heat from the heat gun will soften the glue, and some of it may pull out with the surface. The remaining glue can now be sanded off of the "shelf" with the sanding block. I use a thin, cheap carving gouge to scrape any remaining glue off of the area where the side of the call surface would go.
I also make a smaller sandblock that can be used to sand the surface of the pedestal if this has to be removed. I also use these prior to gluing soundboards and surfaces in on new calls.
Just curious if your replacing the surface or plan on putting a different type surface in it ,,I know my pots are slightly different for each playing surface to get the sound i want ,,Just something to think about ,,
Hi,
I do appreciate all the support. No I didn't make the call and was planning on changing slate to aluminum. Its not like I 'am short on any calls. After all of your knowledgeable inputs I have decided to abandon this project. Someone told me it was the spring fever, but mine has been going on for a few years. :laugh:
Thanks again all
heat some large washers and place in a tuna can......this heats up the calling surface w/o heating the wood
place the calling surface face down to the heat.......
let the surface get hot
take a dropper and add laquer thinner through the sound holes in the back.....enough thinner that it will start to boil..........
lay out some news paper
the surface will fall out.........or fall out with only slight pressure.....
do this in a well ventillated area........
If you used Goop to glue the top surface on you can use the microwave. Warm it and do not cook it. If you warm it slowly it will loosen up and come off. If you cook the call it will burn the wood. Lastly wait until your wife goes to the store before you do it.
LOL I could tote the microwave to the garage. She has already banned me on searing duck breast in the house.
Easiest way is to use a nailset and hammer to break the surface then pry out the pieces. Whole lot faster than trying to heat one too!
Well I'm glad this topic came up. I'm about to have to remove my first surface. I made a good looking laminated pot but did not notice I had a little ridge on the ledge when I glued it up. It does not sit perfectly flush on the ledge and the sound is off. I like Wendell's idea on the sanding disc too. Gonna have to try that one.
If the playing surface is Glass, you can flood the top with Acetone it will seep in around the edges and soften goop. Then take a single edge razor blade and using the corner go around the edges an few times and then put some more acetone on it as it will evaporate pretty fast. Once you can get the blade in there all the way around you may need to add some more acetone and the goop will begin to get really soft then you can pry the glass up without breaking it. If all else fails ....like everyone else said....Put a piece of cloth over the glass and smack it with a hammer!
I gave the old nail trick a try tonight. Worked pretty good. I was pretty surprised to see the Goop was still pliable after being on there a couple months. I went to pop out my sound board from the backside and did not fair as well. Part of the soundboard pedestal came off with it. No big deal. I'll just sand it down flush and glue one in. Other than the little goof up with the pedestal ther was no damage to the call and I'm back in business again.
Here's how I remove a playing surface. Very simple and does a perfect job every time. First get yourself a dent puller the size of your friction call. Then
on a low setting and paying attention not to scorch or burn the wood i program the micro wave for 10 seconds. Take the call out of micro wave and place the dent puller on...and pull up. DONE
my soundboard sits on some metal washers-if I microwave it ........ :o

Honey, why is the microwave on fire? :o I can hear it now. If you try it, be sure to get video and put it on youtube.
I have heard of using washers, but never figured out why... If you turn your pots, try turning a pedestal in the pot. I think you will be pleased with the results.
