oldman_pottering Posted August 24, 2022 Report Share Posted August 24, 2022 (edited) I will start this by letting you guys know that I know nothing and this could be a bit long but I can't explain it very well I have a few pieces of Australian hardwood that I want to be able to use in some smaller projects and the timber needs to be resized to do this. I guess the dimensions of the pieces are not important as the same process would apply to whatever dimension the timber is ( I could be completely wrong too, feel free to correct). The one piece I have in mind at the moment though is 200mm W 35mm H 500mm L and is "machined" (I'm a mechanic and this is how I think of it, maybe it's S4S ?) straight and square but I want to "slice" it up into thinner pieces to be able to use it. I have a good bandsaw and also a thickness planer and I can cut the first "slices" from the outside edges of this block and then run them through the planer because the piece I cut off will already have 1 machined / surfaced side to face down in the thicknesser and I can then mill the other side which will have bandsaw marks in it and obviously won't be 100% square. I would like to know how I go about milling the "slices" I take from the middle of my block as each "slice" will have 2 non machined surfaces leaving me without a good reference edge to lay flat down in the planer / thicknesser. I hope you guys understand what I'm trying to say Regards Geoff Edited August 24, 2022 by oldman_pottering More info Quote Link to comment Share on other sites More sharing options...
Popular Post wtnhighlander Posted August 24, 2022 Popular Post Report Share Posted August 24, 2022 Typical practice is to run the working block through the thicknesser after each slice, so you don't end up with your working block having 2 rough faces. 8 Quote Link to comment Share on other sites More sharing options...
curlyoak Posted August 25, 2022 Report Share Posted August 25, 2022 Your wood could or could not be a good candidate for your requirements. To dress it right I'd want a jointer among your other tools...But that can be addressed with hand tools. Not my specialty. Quote Link to comment Share on other sites More sharing options...
Coop Posted August 25, 2022 Report Share Posted August 25, 2022 @wtnhighlander nailed it. Keep the bottom and the side against the fence flat and perpendicular at all times and only cut from that one side after running your stock thru the planer after each cut. 2 Quote Link to comment Share on other sites More sharing options...

Thanks mate Never even thought of doing that after each cut and I don't think I ever would have.............seems so simple now 3 Quote Link to comment Share on other sites More sharing options...
oldman_pottering Posted November 21, 2022 Author Report Share Posted November 21, 2022 As the above I did what was recommended and then left the timber in my shed untouched and now I have bananas I realise wood moves but........do I need to keep repeating the process or is it a matter of using it as soon as possible after any milling process ? I was hoping to make a simple keepsake box with basic joinery (probably rebates (rabbets) thanks Geoff 1 Quote Link to comment Share on other sites More sharing options...
wtnhighlander Posted November 21, 2022 Report Share Posted November 21, 2022 If you can't use the material immediately, best practice calls for it to be stacked evenly, and restrained from moving, as much as possible. Uneven exposure to moisture in the will usually result in some movement, regardless. True best practice is to mill in stages, evenly from all sides, and save the final dimensioning until as late as possible. Sorry your lumber took the turn that it did! 1 Quote Link to comment Share on other sites More sharing options...

Thanks mate It's all good, I think I will try and redo it when i'm ready to use it. it's approx 11mm thick at the moment, perhaps I can get to 8 mm and use it...............whatever happens I'm getting experience with my thicknesser AND making some nice sawdust 1 Quote Link to comment Share on other sites More sharing options...

Early on I would prepare material so it would be "ready" for use. My experience then was about like yours. Now I mill material as I need it. Another variant is that I make my large panels like table tops at the end of a build. They get finished and attached pretty soon after making them; I don't leave them setting around. 2 Quote Link to comment Share on other sites More sharing options...
Chestnut Posted November 21, 2022 Report Share Posted November 21, 2022 When i cut thin slices from a board i try and do that operation last and try and get the material in place as soon as possible. I have some 1/4" slices from 8/4 boards sitting around that have stayed flat for years but my shop is in my basement and the RH stays pretty consistent and changes slowly all things considered. 1 Quote Link to comment Share on other sites More sharing options...

Thanks to both From now on I'm just going to leave any milling to the end, I was trying to take my time and do things as best I could one step at a time but now I see I'm going to need to change that thought Quote Link to comment Share on other sites More sharing options...
Chestnut Posted November 22, 2022 Report Share Posted November 22, 2022 Another trick I've seen used when material needs to sit longer than you initially anticipated. Wrap the material in plastic. The plastic will keep the moisture around the wood consistent and some people have mentioned that it helps stop movement. Stacking stickering and weighting I think was covered as well. There are a lot of variables here though so it's not always a single silver bullet solution and you may need to just adjust. Also sometimes you have to work with what you've got. I've had to install cupped panels in frame and panel sides before in non-critical situations and just crossed my fingers that the rest of the case would hold things flat. This is not recommended but sometimes you can risk it. 2 Quote Link to comment Share on other sites More sharing options...
