ACG build progress.

One thing to keep in mind with any spalted wood is how far along in the decay process the wood is. To far along and the wood is very soft and pulpy which makes it very hard to work with. Also make sure you wear a mask whenever you work with it as the dust which contains the fungus that causes the spalting can really muck up your lungs. Same with any wood dust but complicated by the fungus in the wood.

Thanks for the suggestions and tips. I've read up a bit in the past on working with spalted woods (which is why I haven't tried beech yet) and I've seen a few ways to improve the stability like having it impregnated with acrlyic as one known wood vendor does and I see you've used this process before as well. If I go through Gilmer for the wood, I know that they can be of great help in choosing pieces for luthier work, so I would get as solid a piece as possible and then see what I could do with epoxy or CA to stabilize it further if need be. The fungus thing has always worried me, I am fairly careful about protection and always wear my mask. I'm allergic to dang near everything that an allergy test can test for, so I always try to be extra careful when working with wood. Again, I thank you for all the help and suggestions, please post some more pictures as you finish it and maybe some more info on how working with it was. Best of luck and keep up the excellent work.

I am just waiting for all the hardware to arrive to work out the control cavity to make sure all the bits will fit in.

Also working on the Redwood Recurve at the same time. Redwood is quiet bad for tear out as it is a soft wood to start with. Sharp tools are essential and it also helps when routing to have a long hard look at the grain direction especially on horns or any tight curves as this is where tear out is most likely to happen. Redwood also is hard work to finish as it is very porous and will drink in finish. I sealed this one with epoxy which hardened the wood and pore filled at the same time.

Thanks for the info. The piece I have feels downtight spongey compared to the other woods I have lying around. It's about 1/4" thick, but I don't think I'd have any problem snapping it with just stiff finger pressure.

Since it's so soft AND with no real grain direction, I should take itty-bitty bites with the router? All I'm figuring to do with it is shape the body, give the edges a roundover, and the basic pup routes. By the time I can do any of that, the micro-plane drill-press thingy will be in, so maybe I should use it for the shaping instead of the router.

SKELF & PROSTHETA: When the time somes, is it OK if I PM you for input?

Same rules as always apply - just take your time with your work and plan your cuts. When doing roundovers, it's a good idea to take bits at a time by gradually lowering the bit each pass. Half depth first pass, 3/4 second and so on. The closer you get to full depth, the more chance the bit has of grabbing material out.

Create a thread for your build so it can all be shared rather than PM I guess.

Feel free to get in touch.

The thread above certainly covers doing the roundover. I lower the bit down very gradually and it is important to buy a good router bit for this job and type of wood. I use the CMT ones they are not cheap but are the best I have found to date.

I agree totally about the quality of CMT bits. I won't settle for less now unless CMT don't do what I need.
