Ripping (resawing) long boards
Question:
What is the best guide/support system for resawing long boards with the bandsaw?
I'm talking six metre oregon here, and I'm ripping some smaller sections.
All my jobs to date have been much smaller lengths, which I've happily kept straight by eye, and balanced on a series of contraptions.
I'm thinking it's a two man job, and a serious fence will be needed, as well as a means of supporting the stuff ( a total of twelve metres of in and outfeed!):eek:
Currently the planks are 200 x 50, and I'm going to end up with some 12 x 20's I hope!
Cheers,
P

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

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!

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.

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

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.

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,

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!!!
