Outdoor Workbench part 4, Wood Movement

An outdoor workbench is more likely to swell and shrink.  As a result careful construction is required.

The outside bolts holding the table to the legs, is normal.

The inside hole for the bolt is a little different so the wood can shift.

Note that the outside hole has the bolt in it already, and the hole is filled with wax mix.

This slit will allow some movement over time, and may keep the wood from spitting.    Wood swells most across the grain.  Since the legs and the top are attached along the same grain intersection,  they should match a bit for expansion and reduce the issue.

The stretcher is matched with it’s greatest expansion axis against the legs least expansion axis.  Cedar is a very stable wood, and this cedar has been seriously wax treated, but this is where a problem could easily arise.  I will be doing a bit more to improve it soon.

The base is also a big, big issue.

Two different woods, treated pine and cedar.  Both have different expansions qualities.  The pine does not expand much along the length, and the cedar will expand a bit along it’s width, so this is potentially a big problem.  If left on it’s own without compensation, it is sure to split the cedar during dry months.

This cedar is actually juniper and it’s greatest expansion axis has a maximum expansion of five point four percent.  Since between the bolts is four inches, the expansion range is a bit under a quarter of an inch.  Does not seem like much, but it can split wood and ruin what could have been a long lasting work.  So I need to modify the base of the legs and the stretcher to be able to handle a quarter of an inch stretch.

Here is where a lot of reading comes in handy, Fine Woodworking has a really nifty workbench that uses a trick that will do perfectly here.

Outdoor Workbench part 3, Tools Needed

Tools used for Worktable

The first tool I show on the bottom right, is an open ended wrench.  the closed end can be ratcheting, but a good open end wrench will last a very long time.  A small set of the basic wrenches can be gotten for about $20, and is a must have tool set.  Probably an SAE and a Metric Set would be good if you plan to be handy in life.

The second thing I show on the bottom right, is a socket wrench with a deep wall impact socket on it.  A good socket wrench, should not have plastic parts.  The ones with plastic tend to stay filthy, and give up early.   The plastic cannot handle the odd oils and solvents that a wrench will often face.   A release button at the top is is a must.   A decent one can be had for around $20.

On the socket wrench is a deep wall, impact socket.  Impact means it can take impact.  Sometimes things get stuck.  Nice to have.  Deep wall means it can handle fairly long bolts.  Also a must have over time.  A set of these can run another $20, and having an SAE and Metric set is also a good idea.

So far, to make this table I have suggested you have sixty dollars worth of tools, and said you should probably have a hundred dollars worth.   So far, I have only described two of the tools on the table.  All told, three hundred dollars will cover all the tools needed here.

The next tool is one of my favorites, the Japanese Socket Awl!  It is easy and fast to use and allows for great precision.  You can get it for under ten dollars.

The nice long clamps are from Harbor Freight and are about ten dollars each unless a sale is going on.  If you plan to do much woodworking, then clamps are a must.  So many clamps.

I am showing a forty inch  Stainless Steel Rule a ten dollar or less tape measure will do fine.  Test the end pushed and pulled, for accuracy.  If it isn’t accurate, then start measuring at one inch and remember to subtract an inch every time you do.  “This is called burning an inch.”

A Brace is for serious drilling,  Power tools are inferior or even dangerous when force is needed.  A used one that will blow away anything you can get for three times the price can usually be gotten from Walt at Brass City Records.  Click on the tools for sale, and tell him that Cedarslayer sent you.

The double edged saw is called a royoba.  One side is for cutting with the grain, the other is for cutting across the grain.  I love the  Razorsaw 650 an amazing saw for about thirty-five dollars.  Japan Woodworker Carries it.

The Long Drill Bit can be had in a set for about thirteen dollars from Harbor Freight.  Long drill bits can drill very deep holes.  They have another profound advantage.  It is much easier to see if you are drilling straight with a long drill bit.  This is a precision hand drill cheat.  I line up my bit using the combination square.  I check it at multiple angles, and then start drilling.  A long bit makes this possible.

A good set of Forstner Drill bits can be a bit pricy.  At the lowest a set may be about fifty bucks.  At the high end, several hundred.   A Forstner can drill, in wood, neat clean, relatively square bottomed holes.  Seriously these are a must have.
I am using a section of a stainless steel ruler as a scraper.  I use it because it works.  A good scraper is a dream for cleaning up wood surfaces.  I just used it on this table to remove splinters.  I am keeping the surface a bit rough for now.  No real reason, this table is going to be a work in progress for a long, long time.  WoodCraft sells a nice set for about fifteen dollars.  You will also need to be able to sharpen it correctly.  There are a lot of way to do it.  Here is my way.
Scraper—It looks like a rule, but I use it as a scraper.  $15 for a set

As far as the vise goes, I didn’t use it on this project.

Big Orange Speed Square—One of the best and cheapest must have tools out there.  Any good hardware store will have one for under ten dollars.

The drill is a Ryobi Lithium 18v one plus.  I do love this power tool.   It comes in a set, and it does the job.  About a hundred dollars for the set, get it around Christmas time for the best deals.  The brace will do the job quite well, so this is not a needed tool.  This speeds me up a bit except when the hole takes a bit more torque to drill.  Then the brace is needed.

Using a Japanese Socket Awl

The Japanese Socket Awl is one of my favorites!  It is great for making starter holes for drilling and lines for accurate measurement and work.   Here is how I use it.

First I find out where I want a mark.  In this case I want a line lined up to match another board so I can drill matching holes.
Awl Stuck into wood
So I lined up the board, and pushed the awl in right where the center of the original board’s hole is.

Then I lay the board down flat, the awl stays in place!Board with awl

Then I bring my square right up to the awl.  Normally I would have a hand on the awl, so I don’t accidentally knock it out with the square but I was using the camera with my spare hand.Awl and Square

Now the awl is almost competely hidden by my hand as I draw it back and make a nice scratch for lining up holes for drilling.
Making a mark

I also pushed holes at two inches and six inches, using this awl so I could then easily start my drill with great accuracy.
Drilling on marks

This gives me fast and fairly precise holes.  If I wanted better precision, then I would use a finer rule than the one on the bright orange combination square.

There, I am all done and quickly.

Outdoor Workbench part 2, Details

This is continued from the original post

First a few more details on the table,WorkTable

The bottom most part of this table is ground contact treated 4×4.
Base

Big holes are drilled halfway up through the base for the bolts to fit.  Smaller holes are drilled through so that the holes shown above allow washers and nuts to be tightened onto the bolts.  All very snug and solid.  One small issue.  Cedar is very acidic, and tends to eat steel.  This is why there is a dark stain around the screws on a cedar picket fence.  I have used my wax mix to try and reduce these issues, but time will tell.  In any case, I don’t want to leave tools out on this table overnight.  Bad idea anyway.

Here is a closer look at the stretcher connection.
Stretcher Connection

The stretcher is what gives stability to this table.

Another View of the Stretcher;

Stretcher

The holes don’t go all the way through, no reason really, I just felt like being different on this part.

The odd part about this table is that it is really two seperate tables.  The gap at the top is two inches, the gap between the legs is four inches.  The legs and stretcher are two by eight cedar, the top is two by ten cedar.  I plan to do all sorts of experimental modifications on this bench, including mouthing a treadle into it.  The split in the center is to be able to run a belt up and provide power to tools on the table top.

Here is the end of the table;

Table End

A very simple design so far, but I have some pretty involved modifications planned. This table is going to end up with all sorts of holes drilled and parts attached.
