Thread: Ripping (resawing) long boards

It might be a lot easier and very much faster to break them down with a hand cs at least until the size is more manageable.

Otherwise you need a long table in and out (which you could knock up outa coupla the 8 x 2's

Which he just cut up into 6x10's.

Al :eek:

I've seen a guide & fence arrangement that used skateboard wheels instead of the usual toothed anti-slip cog guide powerfeed. It was home made & seemed to work well.
It consisted of a false table that the single point fence sat upon. The 'roller guide' was just a long cuphead bolt with 2 or 3 skateboard wheels attached.
The infeed & outfeed tables were 2 sets of roller stands.

If all else fales give the timber to ME!

Hi BitingMidge!

Several questions present themselves:
1: Do you absolutely need to retain a board length of 12m (really? - where'd that come from?) - or can you reduce that to a much more manageable 3m or so?
2: Even with a 3m board you'll need either in- and out-feed tables or multiple rollers - preferably with vertical guides as well to stop the out-feed end of the stock "flapping in the breeze" so to speak.
3: I presume you have either a) a 14" bandsaw with a riser kit, or a 17" / 18" B/S that can take 200mm in stock height.
4: You'll likely need to make a supplementary fence, clamped to the original, that is about 3/4 of the height (e.g. c 150mm) of the board starting size.
5: You'll need to adjust the fence such that it accommodates the natural blade deflection (see Rogowski, et al)
6: You'll also need to make sbsolutely sure that your B/S blade is perpendicular to the table, and absolutely parallel to the fence - or you'll end up with some nice wedges:eek:
7: Best to start with a freshly sharpened (or new) blade - and with that much resawing, you'll likely need a few
8: I do a fair bit of resawing, but not that much at a session. Rather you than me
9: Have you checked out the cost of a professional mill resawing your stock?

Cheers - and good luck!

How come you blokes are giving me hints I'm trying to avoid doing??

Major, maybe I could be persuaded to SWAP some of my ratty old oregon for say, a few cube of silver ash???

Thanks all, I'll keep pondering!!

cheers,

Could you use a similar board on trestles as in/out feed? You'd only need 3 1/2-4 meters on each side. Anything to make it slippery, even stapled on plastic drop sheet would work. A helper, yes indeed. And those fence ideas
already mentioned. That's going to be a pretty fragile 6m plank.

It's preferable,the bits are going to be the Gunwhales and Inwhales of the canoe, but they are actually just on 5m long, so 5outfeed, 5 infeede =10 space required.. I can scarf them, and may have to, but I'll give the long lengths a crack first, if I can pluck up the courage.

2: Even with a 3m board you'll need either in- and out-feed tables or multiple rollers - preferably with vertical guides as well to stop the out-feed end of the stock "flapping in the breeze" so to speak.

It's the table bit I haven't done before, I've used trestles and rollers and all manner of other things, but have been "building up to the need for a table!

3: I presume you have either a) a 14" bandsaw with a riser kit, or a 17" / 18" B/S that can take 200mm in stock height.

Just a standard 14", but that's ok, I'll rip them on the flat, in 30mm or so bits.

4: You'll likely need to make a supplementary fence, clamped to the original, that is about 3/4 of the height (e.g. c 150mm) of the board starting size.

Yep, maybe longer is better too.

5: You'll need to adjust the fence such that it accommodates the natural blade deflection (see Rogowski, et al)

That'll be part of the trick I think.

6: You'll also need to make sbsolutely sure that your B/S blade is perpendicular to the table, and absolutely parallel to the fence - or you'll end up with some nice wedges:eek:

Great point!

7: Best to start with a freshly sharpened (or new) blade - and with that much resawing, you'll likely need a few

Bummer.... maybe it'd be cheaper to buy a few lengths! ??

8: I do a fair bit of resawing, but not that much at a session. Rather you than me

Now you've made me scared!! Or I should say more scared than I already am/was!!

9: Have you checked out the cost of a professional mill resawing your stock?

No, didn't give that a thought, but will do if it doesn't work out!

Thanks for all of the above, we'd better report back on how it all went I think!

G'day Midge,

If I was resawing that sort of stock to your kind of sizes I'd be doing it on the table saw. Why the band saw? OK - wastage but 12mm out of 200mm :confused:

You'll still need infeed & outfeed support or maybe Andrew after all it is his home type timber

FWIW

Regards

Jamie

Midge,
even though I currently have a mother of a table saw with a 3m sliding table, faced with this job I'd set the planks up outside on a couple of saw stools and go for it with a 9" saw fitted with a thin kerf blade. Alternatively you could toss them on your BMW's roof racks:eek: and bring them here to swap for some silver ash. Then I'll rip them up for my boat's spars.

Mick

Funny you say that Mick, I've just borrowed a 9incher from a mate, but with my skinny little biceps, who knows what sort of trouble I'll end up in!

Whatever I do, I've put off the decision another week, and when I set up I WILL be ripping the staves for the new hollow mast for Gruff at the same time!

cheers,

P

What Al said or send them to brother Termite. He’ll take anything.

Here am I tripping over these lengths of oregon, running out of things to do before I need that timber, and almost ALMOST convinced I'm going to cut it in half and rip three metre lengths, when I decided I do one last trawl through the internet to see what I can find.

The very first post I find is my first post above!! :eek: :eek: :eek: :eek: :eek:

So now it seems I'm asking myself for advice as well!!!
