Fishing Net Build

I've been working on making a fishing net, taking inspiration and techniques from some fine examples that Sd_Andy and Nick2cd made.

This is one of those projects that is predominantly an exercise in jig building.

and the steam box equipped with Earlex steamer:

I did a practice steaming/clamping session today. Next step is to cut some wood, steam it, and put it in the jig...see what happens...

I had a nice long day in the shop today.

Before lunch I set up and cut my thin strips. I went with 3/32" thin strips but when five of them are put together they look a little beefy. I may have to go down to 1/16" for later nets, or vary the thickness to obtain an interesting pattern.

After lunch I cranked up the steam box and waited a bit to let things come up to temp. At this elevation (6250') I have a hard time getting the internal temp of the box much over 200 deg. F, so I let the pine box heat up real good, until it's is puffing nicely.

From what I've read a good starting point for successful bending is to apply the steam for one hour for each 1" of thickness of the stock. My steamer produces 1.5 hours of steam which gives me plenty of time. My stock is 3/32"x3/4" and 60"+ long so I figured on what I thought would be a long time but hopefully not too long a time; say 10 to 15 minutes.

So I put my three maple and two walnut strips in the steam box and gave it some time. I open it up and and fumbled them a bit trying to arrange them for the jig. I had practiced putting a strip of wood in the jig, but 5 strips were more challenging. I hadn't thought about if I should put them in one at a time or stack them together and get them in the jig all at once. It wasn't what you would call a smooth operation. 

While futzing with one at a time I snapped one of the walnut strips. Oh well, this isn't a glue up; I'm just trying to pre-form the strips. I continued on with the next maple strip. Then I snapped the second walnut strip. Hmmm, there seems to be a trend going on here. So I clamped in the last maple strip and there is lies cooling over night.

So...what was my problem with the walnut?

Did I have a weak spot in my stock?

Did I steam it too long? Not long enough?

Was I too slow to make the bend or did I not bend it gently enough?

I don't know, but tomorrow I try again and the first variable I'm going to check out is steaming time. I feel like the porous nature of the walnut and my long steaming time may be the culprit.

I'm going to guess you had a grain switch in your strip. A simple grain change, say a few inches from a knot will still give a significant weak spot in a piece so thin. Bending stock needs to be very straight grained or it will snap just like that. 

Ive boiled walnut in a stock pot for an hour before bending, I doubt 15 minutes was too much steam..

I went over to the shop this morning and took the maple strips out of the jig. They sprung back a bit but have a good enough curve for my purposes.

 I stoked up the steam box and put in a couple of strips of walnut. I left them in for an hour and put them in the form without a problem, so it appears that I hadn't steamed yesterday's attempt enough.

Moving on, I cut and shaped a handle and it's ready to glue in tomorrow.

That jig is paying off big time! Dave, I noticed that you are cutting your strips to the left of the blade. I cut mine between the fence and the blade. What are you doing to get accurate thickness. I'd much rather do it your way than mine to save on chopping up my push sticks.

See that stick I have clamped to the table just in front of the featherboard? That stick is secured so that it acts as a stop block. Regardless of how wide my board is, I can adjust the fence so that the board just touches that stick and then rip off the thin strip.

Marc has a video from not too long ago on ripping thin strips (which I recommend.

No Kidding Terry! That's just what I was thinking!
 I could be the only old guy on the court with a zebrawood and wenge racquet. :)

It also occurs to me that a person could make a pretty cool set of badminton racquets.

Or, on a related note, custom ping pong paddles wouldn't even need a jig.
