How Big a Log?....

Im hoping to make a carved chair seat. Ive been searching for a slab of lumber with no success, so now Im going to start looking for a log that will yield a piece of wood 4 thick; 10 wide and 24 long. Ill resaw it to make a piece 2 thick, 20 wide and 24 long. After end checks and cracks, I figure Ill be able to get a piece 18 wide by 20 inches long.

Anyway, Im trying to figure out how big the diameter of the log has to be to yield a quartersawn piece 4 x 10 x 24. I figure I want to avoid the pith, right?
Would a 24 diameter log be big enough?

I've attached a sketch to describe what I'm thinking.

If it matters, Im hoping to get cherry or walnut.

You know it takes forever for a log to dry sufficient. Cherry would be more prone to checking than walnut but working with green wood I think you would have better luck with eastern red cedar or cypress.

Im not planning to dry it as a log. I would cut out the 4 x 10 piece, then resaw it into the 2 thick pieces. Then Id only be 2 years from being able to use it. (Unless I can find someone to kilo dry it for me)

You might save yourself a lot of grief if you would just glue up kiln dried lumber.

I would gladly glue up two pieces of kiln dried lumber, but I cant seem to find a piece big enough.

For a long time I was only able to get lumber 3/4" thick. I made a lot of very large turnings and carvings out of gluing up 3/4. On walnut it isn't difficult to grain match to where when it's done you can hardly tell it was made of thinner stock.

Hello Quickstep,

Let me know if my advice here is not in your style or the way you want to approach this?

I will just follow along otherwise.

These types of chair bottoms are usually made of green wood...not dry lumber!!!. Its not how it was or is done typically, and the thought of doing this with "dry lumber" is a..."modern concept." So I commend you on trying it "old school"!!

The type of wood does matter even though the approach is pretty much the same for the most part.

For beginners a nice bolt of White Pine is a great "first try." You want a bolt section between the "limb whirls." Many other species will work well too...What do you want or have?

At this stage however things really do go "old school" as you are going to rive the wood out of the bolt section...So I will be quiet now if you want to do it some other way?

Good Luck!!

Kinda like these air dried....OR maybe there might still be a few chunks to rive.

Not size of logs marked on the ends and when cut 04/16 ....2 seperate logs...I would have to confirm as I sold one a few months back of the many I have.

2nd log has white streaks...BUT may be a little smaller than desired.

Well now...those be some mighty sweet slabs!!! No need to really rive such fine stock! Just some very pleasant shaping with fine edges for the task of solid wood chair bottoms.



Note: if you do have access to such things as these beauties...the sky is the limit in what can come of them...

walllumber.com has all kinds of lumber up to 16/4 thickness and some even 16" and wider.

As they used to say, "let your finders do the walking." What you need is easy to find.

Thanks for the tip, I thought I’d looked everywhere. But, I don’t see any 16/4 walnut or cherry on the site. Also, most lumber yards don’t want to sell a short piece.

I imagine, as I sit here sipping my morning coffee, and watching this snow storm roll by, that like many of us (me included) that start (or are) getting into such projects as Quickstep is alluding to...they both won't to save money (who doesn't) and try their hand at a "stomp to chair" project...The popularity of Alexander's "Make a chair from a tree" and related text on traditional Windsor Chairs, along with the boundless workshops that have been conducted around such tome over the decades is testament to that interest by many...

Here's a link to my short walnut logs cut http://www.tsmfarms.com/walnut-shorts.html . I normally try to do slide show of all flitches in log starting top , open as bookmatch and continue down through stack showing the front in one pic with back in next so you see actual order and bookmatches.

My numbering system on the end of log AND usually as the control # will read something like this
20" x 21" - 67"L sometimes a 3rd width is used with crotch slabs....It is basically widest width end x widest width other end (x sometimes 3rd W that would be a odd middle) - Length (W" x W" x L").

Sorry I haven't been sawing as much in the last year and half.... I keep MANY irons in the fire and the primary incomer gets priority....We have replaced our saw with a wider Cooks 52" superwide....weather has been hades here for outdoor work on farm so the start-up has been delayed. We've added a show for April 6-7th in Lebanon TN at "The Mill in Lebanon"..... HHhhhmmmmmMMMM...I see more late nighters coming on.

Enjoy....

Hey QuickStep,

If you haven't seen any of Mr. Chickadee's videos, you may enjoy them...

Here is another video outlining many of the steps by another very talented young woodworker out there creating great stuff and keeping the skills alive!

This style (and modality) of chair making is perhaps one of the most elegant from the 18th century...and with...perhaps the broadest range of approaches in creating them. The basics are the same, but the "hidden" trade secrets that went into these kept some shops open while others failed...
