Thans for beatiful like tutorial Mr thomas

[@ravenadair7451]

Such a beautiful process, thank you for using such detail, I’m beginning the process of refinishing my bass haven’t been able to find too many resources, how long does it need to dry between each coat?

[@MsBossio]

THANKS, muchas gracias por enseñar este trabajo.

[@nickyork8901]

thanks for the very informative and interesting video. May I ask, what type of UV lamps do you use? My reason for asking I have a large UV lightbox similar to yours, but the UVA tubes I use don't seem to be very effective - the tanning process is very slow unless I use sodium nitrite or Old Wood ground.

It want to stain the small blemishes i have in mine but sont know what to use. What can i use to stain ?

[@dividedwords]

Beautiful! Thanks for this. Can anyone tell me, what music is used for the background?

[@ThomasGeorgeViolinMakers]

You can find the music on Isabella Stewart Gardner Museum, Boston - www.gardnermuseum.org

7:46 is that oil?

[@dhtsoaedsdhtnadi9575]

oxidizing agent... i think in the episode where you glue the plates to the ribs, i read potassium silicate on the side of a container that darkened the inside. according to an article in scientific american, despite speculation that strad used potassium to oxidize his pieces, spectometry does not show this compound present in any of the instruments tested. i guess one possible method to oxidize is fuming, but that requires tannins in the wood. maple isn't exactly tannic.

[@ozgundemirr]

would be nice if you'd given us some in about the stain you use

[@kamanaos4643]

🤐

[@MrNedelcuBogdan]

What it the stuff you apply on the white wood???

[@ThomasGeorgeViolinMakers]

it is a water-based oxidising undercoat :D

[@MrNedelcuBogdan]

Can you confirm that it's potassium bicromate? Or it is mixed with some other chemicals? Can you tell what is it?

[@brunomaiamusician]

Regarding, the varnish , that is traditionally kept secret by violin makers. But I guess it also has something to do with those chicken.

[@ThomasGeorgeViolinMakers]

Hahaha, the chickens are 100% the secret

[@nagylaj01]

The oxidiser is Sodium Nitrite or something like that. Gives nice hue. But after it the stain is way too dark. And because lack of sealing on the top, the lighter rings soakes more stain. This gives an unpleasant negative effect. What a pity.
