View Full Version : Wood find

I just found this at my local wood supplier - a 12 ft length of 6x2 sapele with an amazing ribbon or flame figure.
103568
Because of the presence of tiny pin size worm holes at intervals along the length, it was priced at an irresistible 25.
Moisture content is currently 9%, and I am hoping my bandsaw can muster the power to convert this into soprano and concert sets, though I'll be needing a new blade.
Any advice on the conversion process welcome! It isn't quartered, more like 45 degrees, but the figure runs all the way through.

Have any problems with this Paul, pop over and we'll convert it no problem together on my dedicated resaw. I have plenty of new blades...

Many thanks for the offer Pete. My Axminster BS11 should in theory be up to the task, but if not I'll be in touch! Are you using the Tuffsaws "SuperTuff Fastcut" blades with the unset tooth? http://www.tuffsaws.co.uk/index.php?route=product/category&path=4_15_91

Yes. They work very well.

Nice find Paul, should get a few sets from that, and would make some nice necks too( probably laminated). Mike

Nice score. The "worm" holes can be filled. Probably not caused by worms but by what we call over here powder post beetle larvae. Be aware that the little bastards lay their eggs in those holes so kill them now before they continue to eat your excellent find which does have some nice flame. Lotta ukes in there... The concept of quarter sawn wood still confuses me at times, but you say it was probably sawn at a 45 degree angle from the log, wouldn't that make it quarter sawn?

That's an incredible buy. I use sapele for necks and I pay a lot more than that for plain stuff. Don't worry about the angle of the grain, it's not exactly slab cut. I'd be tempted to use it all for body wood

I think these holes are due to ambrosia beetle and larvae, which as far as I can discover only attack growing trees or freshly felled logs. The holes are small diameter, quite deep, run across the grain and are black on the inside - which I gather are all characteristics of ambrosia. It doesn't attack seasoned wood, and kiln drying sees it off. Classed as "no treatment required" by specialist wood treatment companies.

I've ordered a couple of the supertuff fastcut blades, so I'll give resaw a try in a few days.

Any tips for resawing old furniture. I picked up a large table for 40 a year ago from fleabay with the intent to turn into ukes when my current stash runs out. Its more or less all perfectly quarter sawn 5/6" sections but over a metre wide.103582103583

Nice piece of oak. I'd separate out the boards and take it from there sawing each board and then cutting sets out of the yield. I would also shoot for 4 slices per board. I am trying to source some larch which teams up well with oak. Get in touch when you have your sets and I'll let you have a set to play with :)

First lot of concert sets successfully sawn this morning. Have to say I am really pleased with both the Axminster BS11 saw and the supertuff fastcut blade. The BS11 may be only a 250mm benchtop saw, but one incorporating all the features you would expect on a full size floor standing machine (heavy cast iron wheels, 3 bearing guides top & bottom etc.). I have mounted it on a wheeled cabinet which also houses my Fein dust extractor, since in my somewhat compact workshop I need to be able to move it easily. I also like the table at chest height as provided by a benchtop machine. Its expensive, but the quality is there.

Anyway, set up with the Tuffsaws 1/2" supertuff fastcut blade in accordance with the teachings of Alex Snodgrass, it coped very well with the sapele.

I actually have two alternative sets of sides cut - one set incorporating the full flame figure which I have some trepidation about bending :), the other sets are from the plainer side of the timber.

Struggling to get the bandsaw pic to appear vertically!

Anyone know how to delete photos / attachments? I can't find a delete option anywhere. I tried to delete a photo and it has just appeared as an attachment instead!

Hi Paul, try editing your post, and highlight the code which represents the pictures. Then press the delete key on your keyboard, not the delete button in the edit script. This seems to actually delete the code, but the edit delete key doesn't.
Cheers Mike

That is cut very thick Paul? What did you set your saw at?

Wildestcat
10-13-2017, 10:15 AM
Pete: I set up for 4 mm thick slices. I like to join my tops & backs at 4 mm, and with 45 mm thick wood I could easily get 8 slices at 4 mm + 1 mm kerf. I didn't think 10 slices x 3 mm would have been practicable given my inexperience. The final slice was a little thicker as all the vertical fence/blade alignment errors compounded. I probably should have re-squared the edge as I progressed, but I'll be taking these down on the drum sander so wasn't too bothered. I'm happy with four 6-piece concert sets with 4 spare sets of sides from less than 1/3 of the timber I picked up :)

Mike: I thought that's what I did! I'll have another go ...

Pretty sure that's what I did first time around Mike - the offending picture disappeared from the main body of the text but re-appeared as an attachment. I've just tried again with all the editing features I can find (including in "manage attachments") but no luck finding a delete option.:confused:

Hi Paul, just tried it on one of my posts and it seemed to go like this. Go to the post , click edit, then "go advanced", then manage attachments. The pictures relating to the post are at the bottom in the attachments pane. I ticked the box on the picture, and then (if I can remember correctly) I right clicked on the picture which gave me the delete option. It deleted the picture ok.

Thanks Mike - sorted! There is a cross which appears top right of the thumbnail once the attachment is selected - hadn't spotted that before.

I've just completed the first concert uke from this piece of figured sapele - a bit of a rush to get it ready for my youngest grandsons Christmas present, but just made the deadline! A few corners cut, but the mark on the front binding is actually in the wood, not filler. Wish I could say the same for the purfling ends :o. I filled the tiny worm holes with an epoxy & sanding dust mix.

I was able to cut two sets of sides for each top & back set - one from the highly figured part of the timber and one from the plainer side. The figured sides were simply impossible for me to hand bend, and I suspect the remainder will find a use in neck laminations or cigar box designs.

Wow Paul, that's great. The wood is beautiful, some of the nicest wood I've seen regardless of what it is. Well done on the find and the build.

Thanks for the kind words everyone - have to say I'm chuffed with how it has turned out, particularly since I think I will get at least 8 full concert sets and 8 soprano sets from the board. The only issue is with bending the sides - even the plainer set took me a long, long time to hand bend.

How does it sound? Well I find it difficult to put sounds into words, but starting from the fact that overall I think it sounds pretty good, the first adjectives that spring to mind are "clear" and "bright" with plenty of volume.

Whilst I have always been pretty happy with the tone from my concerts, they have hitherto been lacking a little in volume.

For this one (and the spruce & London plane example I completed alongside it), I made several changes to previous:

1) Tops thinned by ~ 0.1 mm to ~1.75 mm for the sapele and ~1.95 mm for the spruce (before final sanding).
2) Bridge plates thinned a further 0.1 mm to 1.7 mm.
3) Fan braces stopped short of the lower soundhole brace and tapered away to nothing, where previously they would have butted up to it.
4) Fan brace profile changed from "peaked" to the continuous curved shape I used on a batch of three baritones built earlier this year, which in turn were derived from the bracing I used on my Cumpiano inspired nylon string guitar. Coincidentally, the latest in Pete Howletts truly excellent ukulele club workshop videos shows a similar development.
5) Bridge reduced 6 mm in width (or is that length? the longest dimension anyway) and switched to a lighter, pinless design.

This is the spruce/London plane concert, but the sapele one is the same: 105456 Earlier example for comparison: 105457

So now I'm happy with the volume as well :)

With the success of the Martin OX laminates, even the formica countertops are looking good!

Big thumbs up on this. I think it makes a big difference. Structurally weaker sure. But allows the lower bout to vibrate free without damping. That lower brace can really suck up vibrations and kill the projection. .... Nice looking uke by the way. Very nicely done.

Here are the latest two to emerge from this billet - another concert plus a soprano. Usual batch of cock-ups and senior moments during construction e.g. the upside down flame on the soprano and the tenor size bridge on the concert :o but hey ho I've stopped worrying about it. They both play nicely and having settled in a bit sound pretty good to my ears. Hoping to have them an show/for sale at MUMF in May.

Sorry about the sideways photos - they are the right way up on my PC! Anyone know how to sort this out?

As I've mentioned previously, this is the hardest wood to hand bend I have yet encountered - worse than ovangkol and that's saying something. Sides from the figured part of the board are simply impossible for me.
Some of the wreckage accrued ...

MUMF looks really cool.. wonder if there are similar events in US.
Are you open to shipping it to US and selling them here? ;-)

Hi. Thanks for the interest in the instruments, but they will only be available at MUMF or in the UK if I still have them after that.
