Sold 200x Mapes $5 Chips (1 Viewer)

Up for sale is 2 racks of Mapes $5s. These chips have all been flattened, and are probably the best Mapes $5s you are likely to come across for this reason, as most Mapes chips have severe warpage problems (see pics below of before vs after flattening). I also have the 50c fracs and New China Club $1s for sale.

Price is $550 per rack + shipping

Good luck!

I'm Curious about how you do this flattening process.
How are you doing this ???

Is it hard to flatten them? Id hate to mess em up.

Selling... Why??

Because I got an offer I couldn't refuse for part of my Mapes set which allowed me to fill my 2nd rack of Pick Hobson fracs, as well as a couple dozen more of my grail chips After that, I decided to focus on my grail sets, so I'm letting a lot of other stuff go... Here are a couple pics of where my grail chips are at now...

I can walk you through it. I used a clamp with ceramic blanks between each chip, then heated them 10 chips at a time at 130F for 30 minutes. Here are a couple pics of them clamped:

The wood clamp is a nice touch. Metallic clamps may facilitate too much heat transfer into the outermost chips, although adding an extra ceramic chip at each end is suspected (confirmed?) to address this.

Wow..well done. I may ship some racks to you if you want to offer this as a service. How hot does an EZ bake oven get? (I'm totally serious...lol)

I'm not sure about how hot the EZ bake ovens get (I think I recall someone saying 175F?). We actually discussed this in another thread. I first set up a hair dryer "oven" that I made out of some aluminum foil and a snowboard boot box with a meat thermometer. It actually worked pretty well, but I had to sit there and hold the hair dryer. I ended up using a suggestion by @bentax1978 to use a few incandescent light bulbs inside my oven to get it up to 130F. Worked perfectly.

It takes a REALLY long time to do it unless you get multiple clamps. It took me about two months to flatten all my Mapes. I was basically doing 10 chips per day. Because you have to leave them clamped until they cool off, and I didn't want to put them in the fridge as I wanted them to cool slowly. I usually ended up leaving them over night in the clamps after heating them. I know you can do 20 chips at a time side by side in those clamps, but there's just too much variance in thickness for me to want to do it that way. I wanted them as close to perfect as I could get them. I wanted as little 'gamble' as possible with the project, being is that they are Mapes after all (y) :thumbsup:

Plus, getting them all perfectly centered on the ceramic blanks is tricky. 10 chips at a time worked well for me.

Thanks for all these détails.

So in your before/after pictures is that the same rack? Did you gain room enough to fit a spacer? The before pics dont look that bad to me, but I guess it makes a big difference.

 

[AfterTheFact]

I used metal clamps and no spacers. (Mostly because I didn't have any blank ceramics). I used a block of wood on each end and nothing in between the chips.
I did NOT use an artificial heat source. I simply put them outside covered by a towel but in direct sunlight. These were severely warped Paulsons and it worked well. After a couple of hours in the sun I cracked the vise down another crank and left for a few more hours. It's summer and mid 90's every day here.

Now, these were NOT high dollar chips. It worked very well and there was no ghosting. Here are a couple of before and after pics.

Not to derail, but my 5s don't have warping issues. Mapes are always get the most attention from my chipping and non-chipping friends that visit the Panel Palace. GLWS!

Ya, it's the same rack. I couldn't fit the spacer before. The biggest difference though is in how much wobble was removed from the stacks.
