Pine flooring ply for the top. The light colour contrasts with items like small drill bits. I think mine is 24mm thick. Waist high or a bit higher is a comfortable working height. Ideally, anchor the base to the floor so it doesn't move at all but you can move around it as necessary. Mine is fixed t...

Coffs Coast holiday. Denwar Harps visit

A few months ago I mentioned in a post that we were planning a holiday on the NSW coast South of Coffs Harbour where we have a 9 acre property. Uke builder, Michael Connor, kindly offered us a workshop tour on our way South from Coolangatta (our point of arrival), but that didn't work out: he was he...

That A grade set seems too cheap for BRW. Warning bells! You get what you pay for. If your mate has the $$$ and is prepared to part with them maybe the higher priced set would be the way to go. Hand built in BRW - a few hundred dollars extra hardly seems an issue.

With Lutz spruce (can't comment on Sitka - never used it.) I don't get those shellac grain ridges. Maybe I've been lucky so far. Surface prep might have something to do with it. I progress through to 1500 grit. On the first guitar I used the True Oil sealer but switched to shellac after the bottle r...

Thanks for posting that bracing pattern Alfred, all good things to consider. This top is Engelman and is .110 right now, and it'll get thinned around the perimeter of the lower bout. Do you have the legs of the x-brace exiting the sides of the bridge, or out the back. The Norman Blake model, and al...

Hi Allen, Thanks for posting about this - a very interesting topic. I've built 3 guitars - another one on the go - based on the same or very similar idea: 13 frets to the body, bridge set further into the lower bout and more distance than usual between the bridge plate and X brace joint. I got the i...

Its a good product but very expensive. I managed to get two rolls of 120 grade before the local home center stopped stocking it (i'm not currently in Oz). Since then I have been using good quality paper + double sided tape and found that worked just as well.

Choice of bridge plate material is said to influence tone. Rock maple is said to have the least effect. i.e. it does not add any perceivable quality to the tone of the instrument. Martin guitars used it, then switched over to IRW for a while in the 1960s or 70s, and then switched back to maple. IRW ...

I've built a Size 5 Terz guitar. Used Scott Antes plans for the basic dimensions, but lightened up the bracing considerably. You can see the finished instrument in this thread. Size 5 Terz Wotta little beauty! That gets my vote. one of these years I would love to build a wee little guitar like that.

Ditto to Dave's comment. That scolloping is really extreme. There's no need to scollop the top half of the X braces. There's not enough meat below the X brace joint to support string tension either. I also scollop braces, but not to that extent. Industry standard for sitka tops is 1/8 inch (3.6mm). ...

This doesn't compare with Craig's beautiful set up. Hope the photo helps though. The drum is home made - a bolt epoxied through a wooden block. Nothing flash but it works. Changing the cloth backed abrasive is a PITA. http://www.anzlf.com/phpBB2/userpix/149_IMG_0136_1.jpg This might also be helpful....

Hi Alfred I never bother buying pumice, I just pick it up at the beach. To process it into powder just give it a rough crush then wash it out in a bucket. Take the floating pumice from the bucket, let it dry then grind it down to a powder (hammer in an old breakfast bowl does the trick). I put this...

It depends on what exactly you're referring to as "silica powder". What exactly is the product? Pumice is basically silica dioxide (Si02). I use Behlens 4F grade pumice for my pumice pore filling.

What I was happiest with was a combination of pumice and egg white. The best and easiest result I got was to use egg white with 400 grit wet and dry with just a little dusting of very fine pumice. It filled much quicker with the pumice in the mix. Would silica powder mixed in with the egg white do ...

Looking at that I was thinking how difficult it must be to properly finish a slotted peg head.
No doubt about jarrah. Made some very classy looking bindings from it but haven't used it yet for a fretboard.
If its at all possible, please post a sound clip.
