One suggestion I would make; instead of "window" glass to sand on, buy a small sheet of plate glass at your local auto glass shop. Plate glass is absolutely flat. The thinner window glass can have ripples, waves, and is generally not flat.

I have had the same thing happen to me. I bought a sanding block for wood workers. It's about two inch's thick milled out of stone to within .oo1" flat. Made all the difference in the world!

My approach is to scrape down the stand-off side walls for the slide channel inside the housing a bit, so to reduce the channel thickness for the slide.

How do you do this evenly all along the slide channel, when it's embedded inside the CX12 housing?

@@BrendanPowerMusicI use the slide as a guide: Put thin tape on the slide to protect its surface. Put the slide in place, and scrape the plastic side rails carefully with a watch driver partly resting on the protected slide surface. Since the slide may travel freely inside its channel, the watch driver shall slide along with it without scraping on the slide surface. Besides, I also have a small honing stone which sits well on top of the slide surface. Protrude the stone edge a bit and slide it alone with the slide in its channel to grind down the said sidewalls.

Ah! Nice work strategy Mansing, thanks for explaining. I might give it a try 🙂

@@BrendanPowerMusic Just be careful not to over-scrape the walls. (Guess how I learnt that 🙂)

Brendan, are you currently selling your custom made sliders for the CX12?

Hello, I love all these improvements you make for the harmonicas. I'm picking up my harmonicas after a decade or so and hate to arrive late to the party of these great inventions, sadly. Will love to upgrade my old CX-12 still, do you know of other customizer that sells either your slide and improved comb, or has its own model to achieve a similar improvement? Thanks in advance!

@BrendanPowerMusic 2 жыл бұрын

Thanks for the kind words. Check out the new Kongsheng KB-12 Boogieman on AliExpress. It's a CX-12 copy but with several improvements, and a very reasonable price.

@@BrendanPowerMusic Great news, thanks! I see that the comb in the KB-12 is somewhat similar to your comb actually (metal over plastic comb). Do the slide happens to be somewhat thicker as well? Maybe even a perfect fit to use those improved parts as an upgrade to the CX-12? ;)

One thing I would like to add regarding the sanding of the comb is that using only away from you motion it is easy to not place the comb completely flat in between strokes. When doing this I sanded more at one end of the comb than the other and ended up having to get a replacement comb. I found it better to place the comb on the sandpaper then move back and forwards without taking it off the sandpaper. This gave me a flat result. Just a word of warning!

@BrendanPowerMusic 5 жыл бұрын

Glad that works for you, but personally I wouldn't trust it; the forward and back strokes could have a different force and lead to one end being sanded thinner. I find using the 'push away' motion gives a very even, flat result if you rotate the piece 180 degrees every 5-10 strokes. I always sand two combs at once in a holding jig, with the tines facing inwards. I've done hundreds of combs that way and checked the finished items with digital calipers; the difference in thickness between ends is invariably within 20 microns (0.02mm). Another hand-sanding method that some advocate is using a figure-of-8 motion, but the twin-comb jig combined with push-stroke direction and regular rotation gives a predictable result I'm happy with. Literally "Different Strokes for Different Folks" I guess ;-)
