Mike Molnar's Bench

Recommended Posts

I glued a Christian Bayon style bass bar in my violin the other day.  I had two closepin type homemade clamps (the other 3 were too big to clamp, I don't usually go as low as 14 mm, and the bar was not as tall) and two big spring clamps.  Left them on for about an hour.  Took them off, and clamped the belly on to the ribs with spring clamps do see how stiff it felt. 

Worked fine.  Even with the almost 2 mm drop to the neck block that I hadn't planed on.  Apparently the top of the block wasn't that square to the side.

I used a piece of Spanish Cedar from a guitar neck I'm making for the bass bar on on the Alaskan Yellow Cedar top.

You don't have to worry about kosher Mike!

Work on the coronaviolin continues. Today I glued the fingerboard and nut onto the neck. I know this clamp setup is not kosher, but it works well for me. Tomorrow, I will remove the clamps and finish up this neck assembly.

I hope that everyone is well and safe.

 

I use a length of twine to clamp my necks. It works great every time. More 'n one way, they say.

I purchased some hardwood ash from a woman in New Hampshire. I put 2 lbs in a 2 quart Mason jar and filled it with filtered water removing any chlorine or other chemicals. I let it stand for about 2 weeks with an occasional shaking. No boiling. I then filtered the liquid through a coffee filter and got what you see in this photo. I quickly dipped one end of scrap maple in the real wood ash solution and the other end in my synthetic version. I feel that there is no significant difference. The real wood ash solution is on the left in the photos. 

This proves to my satisfaction that this is a chemical reaction involving the high pH components, namely KOH and K2CO3. So, I do not do any UV tanning.

BTW, any difference is due to odd wood figure in this trash maple.

Hey Michael, hope you're well. Coronafiddle is looking great. I somehow missed this section of the discussion last time I took a spin through your bench thread.  That's a very interesting color. 

A former teacher of mine used to treat his entire billets and got the wood looking a fair bit like this, but perhaps skewed a little redder/browner. He would never tell us what the trick was. All he would reveal is that he "soaked it in reverse osmosis filtered water in a large stainless steel tank". I suspected, from peripheral conversations, that he may have added wood ash to his water bath. 

Notably, the wood was consistent in color all the way through. I once split a billet of spruce he treated, and the color and texture of the wood were as homogeneous as wood ever is. I've seen people post here about ponding before and split billets to find untreated wood at the center, but this was not the case here.

Since learning of the stuff from Tommy Coleman, I'm clamping boards with surgical rubber tubing. That stuff can do anything!
