This project is simply to turn rough sawn timer into usable project material.
See image 6 of 6. I might add right from the outset this project is pitched at those learning woodworking and the results you can obtain from rough sawn lumber, its possible of no interest in any way to advanced skilled woodworkers.

Background:-
Upon my completion of my wood repair at Smiths Chips I had remaining stack of Aust hardwood.
Planks and bearers along with metal angle 50×50 x 3mm

The 150×25 x 1160 mm planks were milled up to make beehives so they have now gone.

The bearers 90×45 x 1160 I took a good hard look at and thought I could dress them and produce 2×19 mm x 85 mm x 1160 planks as a result and use them for cupboard door construction.

The Process:-

Preparing workable surfaces.
First of all I examined the stock and determined the faces and edges suitable for jointing.

See image no 5 of 6.
The jointer
To do this you use a straight edge to determine cupping and bowing on the face and edge of the timber.
Mark the edges and faces you intend to joint if the defect is only slight and not obvious.
The bow or cup has to face up an the lowest points being the ends of the timber face down on the jointer otherwise the bow down will not achieve a flat surface
Start with the face side and continue until its almost completely flat, the reason I say almost completely flat is if the timber has checks or split and other defects at the ends it will be cut off anyway.
See image No 4 of 6,
Next using the jointer set to exactly 90 deg to the bed joint the edge the same way.
Yo mow have a face and edge both flat and at 90 deg to each other.
The job for the jointer is now complete and it can be put away.
The Thicknesser
Next the thiicknesser is used to produce a parallel and flat face surface.
You can if you wish group them together jointed edge down and do the edges or just use a table saw on individual pieces.

You now have dressed timber to work with.

The table saw
Set the table saw to about 20 or 21mm and rip the boards face wise, this produces planks once finally thicknessed of a useable 19 mm thick.
Dont do the rip in one pass its too much of a strain on the machine do 2 x cuts from either edge, your going to do a final thickmess anyway.
See image 1 of 6.

Now for the other off cuts, if the bows and cups were not too great you may have a second plank able to be thicknessed to again 19 mm.
I think I only obtained 1 x plank for the 19mm stack.
The remainder were 17 and 18 mm so they got thicknessed to 16mm.
See image 3 of 6.
A couple were less than 15mm and 13mm so the finished up at 12mm.
The reason being after jointing and deducting the saw kerf it was not physically possible.

So what are they now all for?

no exact next project in mind but the activity provided me with some more practically dimensioned timber to work with.

Quite a lot of work but produced some nice workable timber which had nice features then the gnarly looking original bearers.
Conclusion:- You can also achieve the same results using a straight edge and table saw or a bandsaw, the bandsaw producing more pieces able to be finished to 19 mm due to its thin kerf.

Thanks for sharing this info.

It’s always good to see how others do this.

I just finished something like this with a pile of walnut, another of oak, and some cherry using a bandsaw, planer, jointer, and table saw. The walnut didn’t yield much as it was well and truly scrap, though I did get some decent boards out of it. The cherry and oak turned out better. Processing all of the wood has taken the better part of a month, working a few hours a night during the week and spending more time on weekends.

Around the Midwest (US) there are numerous saw mills where you can buy both rough wood like you mention as well as more finished wood. Rough cut boards from there are usually in pretty good shape and don’t make too much work to clean up.

There are also folks that want to sell their stack of air dried wood that has been sitting in a barn. Those boards generally are the ones that take a lot more time and effort, as well as having a lot more waste due to their condition.

You get what you pay for, rough lumber from a saw mill may be more expensive, but you spend less time turning it into something you can use.

Nice work Rob! Thanks for sharing!
Only a woodworker see the beauty in rough sawn boards. Non woodworkers look at it as trash.

I’m a little disappointed that you didn’t use your sander even once Rob.

Rob, some very interesting information and most of which I’ve been using for years as I am one of those guys that buy the air dried wood in the barn.
Thanks for sharing -

Note to noobs, read this post twice. This step is only the most important part of woodworking.

Start with fresh crispy edges, and wood of the same dimension, end up with nice projects. Just start putting it together as you bought it, well, we’re gonna call that “rustic”

Nice post Rob.
