Bent my first madrose side this afternoon, it is still in the bender. Now if I just don't crack the other side.

It bent as easily as the cherry I've been using, with light bulbs, no problem. I thinned it to .085. One thing I understand now with my first rosewood attempt: it really does screw up the sandpaper.    I built three whole cherry guitars with the same paper on my drum and could have built at least two more, but thicknessing the sides of the rosewood was much more trouble. I did have to change paper finally.

Also, bending a $200 set of wood is a much more tense operation than bending a $60 set.

I can't imagine the agony involved in bending BRW.

Ron-
I wonder if there are any tricks to keeping the sandpaper from gumming up? I did some EIR binding strips and it just gummed up the paper something fierce.
Might be worth a thread.

Good luck with that second side!

Ron,

I saw your topic title, "Mad-rose is cooking!" and got an image of some crazed old flame showing up on your doorstep to set up house!

So far, I've bent only one pricey set that had me sweating bon-bons. It was koa though, so it was a piece of cake. Good luck on side 2!

Tony, I only found the "Hook and Loop Stearate Paper Rolls", is that what you use?

There are certain woods that are just going to clog up your paper. Different rosewoods and Cocobolo are some. It helps if you feed the piece through the sander with the grain at an angle for your stock removal. If you finish off with a few light passes going with the grain then hopefully you won't have as much trouble.


I just assume that with some of these woods I am going to go through a lot more paper.

I'm using hook & loop stearate paper, and I used my cleaning stick several times, had to resort to a utility knife and scrape the gum off.    The wood took a lot of sanding, it was pretty much in the rough (from Vikwood). It looks good, but Vikwood doesn't process it nearly to the stage that our sponsors do. (I didn't bypass our sponsors, I've had this set for a long time).     I did feed the wood from several different angles, maybe it was just gummmmmmmmier than some others.

I also got my first rosewood splinters and I need to go dig two out pretty soon.

Yes Arnt .. I use the hook and loop ... but now just wrap it around, wedged at one end, band clamp at the other. I used to have the velcro on the drum (thats what got me used to this paper), but getting the paper on straight so that it would wrap was a real drag - the velcro also had a bit too much give to it.

And yes, some pieces are just way too gummy - I have aset of coco that was really resiny downt eh centre 3 or 4 inches - it destroyed a wrap of paper on its own. Same thing, had to clean the gunk off with an old chisel , but that also wrecks the paper. This stuff can sand mahogany walnut and koa, plus tops all day long.

Way to Go Ron.

So, my first question is where do you buy madrose for $200. That is a great price.

and with respect to the sandpaper, use lots of vacuum, clean it often and use different parts of the drum. If you can keep the paper from getting hot it won't gum up as bad. I just sanded 2 sets of coco and I don't have hardly any build up on an 80 grit roll.

I've solved the "oily wood on the drum sander" problem by useing very
coarse paper to thickness the stock. For instance I use 60 grit to go down
to .100" and then go to finer grits to go to .085" or .090". the 60 grit will
not load up no matter what you do to it, or what you put through it.

That sounds like what I needed. The coarsest grit I have ia 100.    I'll order some tonight. Thanks

The coarser grit thing is something that I forgot to mention in my last post. I now use 60 to thin down the more oily woods and it works great.


I have went through a lot of 80 grit paper over the last few years but my one piece of 60 is holding up very well.

Thanks for the sanding hints, guys!
Lots of good info.

I've been using 38 grit and it really "hoarks" it off quick. (I'll have to pinch that term off Hesh).

I've just thicknessed some Padauk that was 7mm thick down to a bit over 2mm.

If I try and put Padauk through the thicknesser it just spits chips at me.

I'll change to something slightly less aggressive at a bit over 3mm.

Ron, You bend the second side yet? fingers and toes crossed...

I have one set of mad rose, it's purty stuff for sure. Really reminds me of brazilian I've seen. Good luck.

Lance,

Please add "Hoark" to the OLF Glossary of Lutherie Terms. Put it somewhere between the "Crazy Ritz" and "Zoot".

Thank-you.

Ron,

Where did you get your Mad-rose? I'd like to get a couple of sets myself, but I'm having trouble finding really nice sets that I can look at before buying. I looked into ordering from Madinter, but the shipping is very high.

TIA

Post subject: 

Yeah, very.

Getting really killer stuff, the stuff like LMI used to sell as their "special" sets is virtually impossible. Thankfully I grabbed quite a few of those sets while they had them, but as always I wish I would have gotten more.

I just snagged this set from Todd @ allied. He has some sets posted in his weekly specials page (click on page 2)

Brock,

Beautiful set, I think you got the best of the lot, unfortunately for me

Not yet, Bruce. I spent the afternoon at the dentist.
Will try tomorrow afternoon.    If it doesn't work, I might just make a one sided guitar. Big sound port. Yeah, that's what I had planned all along.

That's a beautiful set, Brock. I hope my back looks that good. I haven't started sanding it yet and it is too rough to tell what it looks like, but my sides look almost identical to yours. My back does have sapwood, so I think it will be wonderful. I probably won't sand it until my 60 grit paper arrives.
