Re-Sawing timbers
As I'm sure there is a lot of swing bladers like myself that ask the same question on re-sawing of timber I would like to know what is a good way of re-sawing timber.
I cut a lot of larger dimension timbers on my mill but on occasions come across situations where I would like to re-saw smaller size timbers.
For example early this year I had a client that wanted some Marri cut up for stick flooring(13mm). I cut up the logs into 4 x 4's to get re-sawn into 17mm floor blanks before machining into boards. The smallest I like to cut on the mill is 25mm and even then not happy with the amount of sawdust.
The closest company with a commercial re-saw is over 1 1/2 hrs round trip away so transport is costly and they are very busy and really not interested as expected.
I have come up with 2 options that I can think of as buying a large re-saw or a small woodmizer is not an option. I think a small woodmizer would go great with the Lucas but I cannot afford to go down that track.
1st option is to buy a larger size bandsaw( 20 - 22inch) and re-saw on that but I am concerned about the cutting speed of 400 + Lm of 4 -5 inch stock.
To be realistic I would need to be able to cut that size stock at 15 - 25 ft per min.
2nd option is to use my Altendorf panel saw with a thin kerf blade. By memory it has a 5-6 meter cut on it so length isn't a problem and speed I think would be within my 15 - 25 ft/m range easily but how realistic is the thin kerf blade in relation to staying sharp with cutting large quantities of timber and how much larger cut would it be compared to a bandsaw blade?
I cut primarily Jarrah, Marri and Karri etc and would be mostly greensawn. Any input into my 2 options or other ideas into how other people re-saw there timber would be appreciated.
Thanks...MarkWhen I die, I want to go peacefully like my Grandfather did, in his sleep---not screeming, like the passengers in his car.

I did some re-sizing for a chap recently, I set up a bed with a staidgt edge screwed to bearers, I then ran a second staight edge parallel to the first and spaced slight wider than the stock. I then placed each length between the straight edges and I used small wedges to hold the stock in place. I then re-sawed, removed stock and repeated. It worked well for that job. For smaller timber I use a large Hafco saw bench and a Hafco planner with a 6 ft bed plus rollers.

i couldn't see how the tablesaw could come close to a bandsaw with a power feed fitted and roller bench set up in and out.that's the way i think i'll head down the track

Thanks for that Mike but freight would be a killer on that one. Always good to know if desperate.
Thanks to all the other replies as well. Definitely food for thought.
While at my workshop today I had another couple of ideas in that I have a 10inch table saw that I could setup permanently or my Radial arm saw has a long work bench and can turn 90 deg parallel to my bench. Same as with the panel saw I would need to get a thin kerf blade. If Im not wrong I would also need a powerfeed for the radial arm as I gather it will want to lift up if that makes sense. Do people use the radial arm saw in this way as it locks into position at 90 deg and can be locked along the slide?

if your cutting from bog stock you should get an extra board with a bandsaw blade .
spliting timber and lots of it you need hp on your motor, you might cook the motor or will you get off because the fuse keep popping.
big table saw if you dont mind losing timber with the thicker cut. you can get a old saw for not much investment. plus keep fit pushing the timber through

Mark I'd think you can get a good ripping blade thin kerf on a table saw (just like a no2 bench really) a couple of in feed out feed carriages on rollers, set the fence 17mm from the blade and just keep feeding your 'blanks' through it. this will give you good consistent results and I dare say you could get the production you are after too. Yeah a bandsaw would use a little less timber, but you also have to have a pretty big bandsaw to be able to handle what you want, something with a 2" band and probably 1 or 2 tpi and then you have issues with keeping your cuts spot on...
My money would be on the no 2 bench setupI love my Lucas!! ...just ask me!

Mark,
I would forget about the altendorf, radial arm and small workshop sawbench. Your sawing hardwood and they won't do it for very long and will be painfully slow.
Next I would ask myself do I really want to be bothered with the double handling of resawing - but that's why you started this thread so I guess you have worked out that you can make a dollar doing it.
Sigidi suggestion of a no. 2 bench is what I would go for. They usually run a 36" saw and you will get good production speed that will outweigh the loss from sawdust. I have a band resaw with power feed and it is slower than a number 2 bench even though it has a 75 hp motor and 6" band. I use mine for high value cutting like guitar sets etc. I rarely use it for hardwood. The breast bench is the go for that. Also you can't face off with a bandsaw. You have to follow the cut from your portable mill.
Best bet is to avoid the double handling and don't take on the resaw jobs but if you must............. then copy those who are successful. Nobody resaws for long on joinery type equipment.
cheers

Thanks everyone for your replies. Yeah I think you might be right Steve and Allan and the #2 maybe the way to go.
Come across this for sale and may be worth checking out.
24 inch with just the need of a riving knife, shroud and a 3 phase motor. I think something this size would suit my needs.

I was looking at that last night!!
Im wanting to cut down some roofing beams so I can better use my timber. I recieved a Truck load of Jarrah from a mate when he extended his 20yr old house.
Im looking at building a large blade table saw just for ripping. Something with a 2m bed would be nice.
My biggest problem is if I dont use my timber Ill have to give it away next year!!
So If my mission doesnt work some one will be lucky!
Good luck with your search!
Rick
