One thing that I really believe in is that is cheaper to make a slightly thicker cut and have a useful piece of wood, than to cut to too close to the finish dimension and have nothing but expensive scraps if the cut doesn't go very well.

Basically, being stingy is not being thrifty; being cheap can be expensive.

Still, I abhor waste as much as anyone.

I don't do much resawing, but I still love having two band saws, one 12" and one 24". I say go for it if you can! My big saw is a bit cumbersome to change blades on, especially if I change the blade dimension and have to adjust the guides, I don’t know if that is an issue with your saw.

I remember seeing pictures of Shane Niefer's set up. He has a shop made sled arrangement for resawing, I think he said he got the idea from a FWW article. I can't find the thread now, but it is one where he shows his procedure for processing tonewood.

As for how close to final dimension you can resaw, that probably depends both on the quality equipment and the skill of the sawyer. Like Douglas, I probably stay on the conservative side.

Kent-
1- Yes, you will enjoy having two bandsaws- one for resawing and ripping, and a second, smaller 'utility' saw.

2-Laguna now provides ceramic guides with their 16" saw, though I'm not sure the same guides will fit your saw.
Laguna Guides
I got excellent advice from Don Dedo at Laguna via the telephone- Phone: (800) 234-1976 Ext. 9606
You should give him a call.

Kent-
Just checking the pile of notes here on my desktop...

FYI, Bob Cefalu told me he uses the 1" Lenox Aluminum Master CT on his Laguna16HD, and also recommended the Lenox Trimaster blade. For expensive stuff where thin kerf is a must, he uses the Laguna Resaw King blade.

It doesn't take long to have a lot of $$ hanging on the 'spare blade' peg on the wall!

Cheers
John

As someone mentioned, the Laguna saws now come with their ceramic guides. They came on my, BobC, and Don Williams' saws and I'm pretty fond of them.

I use aluminum cutting blades (not from Lenox, but same geometry) for most stuff and the Resaw King for Brazilian and ebony resawing, as BobC does.

With a blade that leaves a really clean cut, you can get -really- close to final dimension with a properly setup saw. I do some precision resawing for people from time to time, usually on Brazilian or something else expensive, and it makes a whole lot of difference to the customer that they can get their six slices out of an inch. The setup for that takes about an hour, just getting everything on the saw lined up perfectly.

Just out of interest i am now using bi metal blades from a company called
hankinsson they do a 4-6 tpi bi metal blade that is the best blade i have
ever used on my 18" saw.

I must stress that it is only the hankinsson bi metal blades that work for
me i have no luck whatsoever other bi metals in the past.

I will still use lennox for cutting neck blanks and ripping but with the
hankinsson i can cut to 3.2mm with saw marks you hardly see.

In fact it saves me having to sand with most woods (especialy rosewoods)
as the saw marks are so fine.

But as Bob says set up is essential and the saw HAS to be cleaned and
reset up for every billet.

Time consuming but critaical to good resawing.

Joel.

Hi Kent,

I have an 18" saw dedicated for resawing and ripping and a little 10" Delta which I use for curves. Having the second cheap-o saw is very convenient, plus the blades for the smaller saw are much cheaper than blades for the big one so that helps recoup some of the cost of an extra saw.

For resawing I really like the Lenox Trimaster. It cuts smooth, fast, and reliably. I have the 1" blade and there's absolutely no blade lead so it's really quick to set up. The kerf is large, though, I think I lose about 1/16" per cut. Another downside is that it's a pretty expensive blade.

If you need a smaller kerf for a really expensive board you might look at the woodslicer blade that Highland Woodworking sells. There's pretty much zero set so it has a very thin kerf (1/32" if memory serves) and leaves a very smooth surface. It dulls very quickly though and easily wanders once dull - especially in figured wood - which can quickly ruin your day.

Thanks all. OK, OK, twist my arm. I'll get another saw.

The more I get into this, the more of a job it looks like. I won't have time to really deal with it till January but it's going to take some work to get this thing in good shape. The sliding track that the upper wheel rides in, where the tension adjust is, allows the wheel about 1/8" of side to side play! I haven't had the wheel off to look at it but I don't see an easy fix. And the guide arm is pretty funky too.

John, thanks for the Don's name at Laguna. Looks like I'm going to need some help.

Doug, yes I've learned the hard way that trying to cut it too close is the opposite of saving. But I can't help but be an optimist!

Bob, why use the Resaw King only on the good stuff? Is it slow or is it just to minimize the use of the expensive blade? And what kind of final sanded thickness can you get with 6 slices/inch? I'd love to get that.

Ringo, how do you like your 10" Delta?

The resaw king is a very, very expensive blade (4-5X what I pay for the aluminum-master type blades) and because of the tooth geometry and super-thin kerf, it cuts slower and dulls much quicker than the other blades.

When going for six slices, I use the Resaw King. The stellite teeth on it are a lot like a table-saw blades teeth, so they leave a very smooth surface on the wood when it's cut. If you're careful, you can essentially go to finish sanding on the surface that blade leaves. In this case, you'd be able to get 100 to 120 thou slices.

The new ceramic guides rock. There are basically four contact points instead of two. It holds the blade really well on track. In fact, I never have any issues with blade wander. I never have to set the fence for drift like a lot of folks do with other saws. I'm not sure how much of that has to do with the guides, but I'm betting they help a lot with it.

Only badly."

I use Lennox Woodmaster for Spruce and cedars(1" 1.3TPI), Lennox Trimaster for most other hardwoods, Occasionally I use woodslicers for low loss cutting. The problem I have found with the thin kerf tight set blades is that they do tend to wander if you do not slow down enough for them to clear extreamly well. This makes them touchy and a little more risky. If you are sawing a lot of wood, it is usually better to go for the trimaster (reliable, and speedy).

Cleaning your guides and blade is HUGELY important to me. About the best way I can think of to keep things running well. I am not running ceramic guides, but am running extra wide single bearings(not the standard ball bearing style), and find they give me little trouble.

I use my slider table for squaring wood more than resawing(I hate resetting things between slices). I use my fence to do most of my resawing. I did notch the outfeed side of my fence to allow for the problem you mention. As I feed the material I pretty much focus on keeping the material snug to the infeed side of my fence just before the blade.

As far as kerf, I find kerf is what the kerf is. I don't have much deviation from cut to cut, which is really important when you surface the wood. You want to be able to set your sander, and feed piece after piece with no resetting. If you think your blade is wandering a bit, you may be having issues with the blade clearing the cut. If you see sawdust building up in the cut then you need to allow the blade more time to clear. I find oily woods like Cocobolo are really touchy about this as the dust really likes to clog if you try to move too fast.

Good luck!
Rich

[/QUOTE]

It is a light-duty machine, but I pretty much only use it for cutting curves so I rarely have to cut through wood thicker than an inch or two. For me this type of work depends more on a sharp blade and a slow hand than a beefy frame and more power. I would think pretty much any entry level machine at the local home improvement mega store would work well provided it doesn't have tracking/vibration problems.

Bob-
Where do you get your Aluminum Master CT blades? (I wanna know where to get one for $50! )
The best price I've seen online is $162 + shipping at Spectrum Supply for a 150" blade for the Laguna 16HD.
Laguna is charging $240 for the Resaw King in the same size.
All these prices take my breath away, anyhow.....

Cheers
John

I don't use the Aluminum master blades, I use some sort of bi-metal blades I got from R&D Bandsaws. I asked for something with specs as close to the AM blades as I could get since I know the other guys have had good results with them. They cut me an awfully good deal on the blades, and they were good to deal with.

Ah, now I understand- thanks, Bob.
I've dealt with R&D 'a bunch' and have always been very happy with the service and the blades- good prices and the shipping is VERY reasonable- under $10 in most cases.
I've had good results with their 'Little Ripper' blades (not on a Laguna, though) and at $25 (on special) for any length up to 150", the price can't be beat.

Bob-if you find the R&D spec/catalog # for the blades you use, I'd appreciate it if you could pass it on. With the concerns about privacy/identity theft these days, I'm not sure that R&D would look up your invoices and find the info for me. Thanks!

John
