Danish Chairbuilding Extravaganza 2018, day 4

Yesterday we all worked like crazy. Somehow Thursday manages to slip itself in every time we have those events - and it is a stern reminder that we ought to get closer to completion of a chair or two.

Ty needed to get some really precise holes drilled in his frame assembly. My pillar drill is incredibly inaccurate, and those holes were sort of make it or break it for the project- As luck would have it, Olav had acquired a professional pillar drill /milling machine some time ago, and we drove to the workshop where it still is. (He hasn't moved it home yet).

We got all the holes drilled, two that were square to the surface, two that were at a 15.6 degrees and two that were 14.7 degrees to the surface (like all chair making angles it is measured from 90 degrees.)
This machine was up to the task and I am a quite a bit jealous at Olav for having such a nice machine.
Good thing that I can borrow it though :-)

Brian started adzing out his seat, and he has made good progress.

I worked on the seat and got all the holes laid out and drilled. Next I made the legs and that was done with the copy attachment on my lathe. This attachment works really well, and the whitebeam gave a nice surface.  I am not a fast turner, but using this attachment made it both fast and I ended up having four identical looking legs.

Olav continued on the shaving horse, and was mostly occupied in making huge mortises in the base and the upper rest part.

Danish Chairbuilding Extravaganza 2018, day 3

I felt like rephrasing the title post used by Ray Schwanenberger some years ago when I first spotted the nanny rocker, instead mine would be:
Oh heck, is it already Wednesday!

I feel that I should be half done with the chair by now, because clearly Ray is able to complete the chair from starting out quietly Monday morning and being all done on Wednesday. At least that is what I imagine from his blog post (I have very high thoughts on Rays work as you might have guessed).

Well my Wednesday saw me completing the sack back bend, and from then on it was spindle making time.

There are 28 short spindles and 7 long ones. I discovered that I could make them much faster and better looking using a spokeshave than I could on the lathe.
Before calling it a day, I started sanding them, but I didn't get all of them done, so I'll have to continue with that today.

Generally there has been a steady progress on everyone's projects, and it is interesting to watch the different techniques employed at each participant's workbench.

Danish Chairbuilding Extravaganza 2018, day 2

I made a bending form for the sack back and then I readjusted the bending form for the arm crest, so it would fit the plans I got from Ray Schwanenberger.

The sack back bending from is advanced for me, because you need to bend it in two planes.
I made three attempts at that, but all of them broke. So I'll have to see if I can get it done today.

Of other things I managed to flatten the seat for the chair/cradle and I made a run of the short spindles that I tapered. But there is still a bit of a way to go.

As usual I forgot to take many pictures, so all I have for you today are 4 "crappy" shots,

Everyone else in the shop seems to be making great progress, which is really nice, because it means that as a whole, we are all getting better at building chairs.

We forgot to buy some new pastries, so we failed to live up to our own goal in that respect, But to compensate for that we had an opulent dinner with all the bells and whistles (Waldorf salad etc.)

Danish Chairbuilding Extravaganza 2018, day 1

DCBE day minus 1, Olav and I drove to Aalborg Airport to pick up Brian Eve.
We had a great ride home and Brian was impressed that the Danish legislation allows you to drink a beer while inside the car. Even the driver can have a beer, just as long as he/she stays below the BAC limit of 0.5 per mille.

Earlier that day, I had picked up the extra workbenches at Olavs place, and Olav and I helped each other unloading them at my shop, so all was ready for building some chairs.

The first day started with going through the stock of wide boards and determining which things we wanted to build.
Brian has decided to make a Velda's rocker, Olav wants to make a shaving horse, Ty is doing a new design and I am going to attempt making a sack back nanny rocker.

Ray Schwanenberger had graciously offered to send me a copy of the plans for his nanny rocker.

They were scheduled to arrive Saturday, but thanks to the incompetence, lack of service and skills by the Danish Mail (which is now called Post Nord), the planes didn't arrive until Monday afternoon.

Fearing that the plans might not arrive until the end of the week, I started designing my own nanny rocker. I made it as far as building a bending form for the arm crest, and then suddenly the real plans were available to me.
Those plans are spectacular - nothing less!.
I decided to ditch my own design and follow the plans, then I would know that the concept would work and I can always try out my own design when I have built my first NR (nanny rocker).
So I sort of started from the beginning again in the early evening, so that's why I haven't got a lot of impressive stuff to show.

In addition to this I forgot to take a lot of pictures during the day..

Danish Chairbuilding Extravaganza 2018, preparations

I'm signing off tomorrow afternoon, so I should be home early Wednesday morning.
That will give me a bit of time for preparing the oncoming DCBE.

There are a couple of things that needs to be done prior to getting the shop filled with people.

First I have to remove Gustav's mopeds from the shop, and also the motorcycle lift that is currently residing in one part of the shop. Then I need to do a thorough clearing up and cleaning, so it will look nice an inviting.

I'll have to arrange with Olav to pick up some extra workbenches, and have those put in the shop as well.

There is likely going to be some steam bending this time, so I have decided to make a proper steam box, instead of relying on my old gutter pipe balancing on top of a micro deep fat fryer.
There was one sheet of plywood left over from building the two Mini Max hydroplanes, and that should be sufficient for a steam box. I need to buy a wall paper steamer for supplying the actual steam, but I think that they have those at at the local home center.

I would like to make some sort of kiln as well, but I am not completely sure if I'll do it from scratch. An idea that has crossed my mind is to just get my hands on an old cabinet and install a heater inside that. But I think the steam box is more important, so the kiln might just have to wait.
In a pinch it should be possible to stack some insulation around an old table, and then put the heater below that. So given that there are a bit more options for that I am not so worried about the kiln.

I need to go and talk to the caterer, and discuss a menu for the week, and agree on when I should come and pick up the food. That is a very important thing, since we need to be well fed to yield maximum power!

Due to the planned return to chairs featuring some turnings, I thought that it might be a good idea to see if I could get my act together, and install an electric motor on an old wooden lathe that I bought at an auction in Sweden maybe 15 years ago. I don't want to make a foundation for it, so it will just be clamped to my workbench. That way there shouldn't be a traffic cork for a lathe when the need arises.

As usual I am probably way too optimistic regarding how much I am able to achieve in a few days, considering that I also plan on talking Bertha for long walks, ride in the forest with Mette, and I have signed up to chaperone the first school dance at Gustav's boarding school.
But on the other hand, once in a while I am actually able to impress myself with being efficient, and I hope I will be able to do just that this time too.

Making a tenon saw 2, saw completed.

Fabricating the handle was just like what I did for the Simpson saw, but I had planed a little bit more of the blank before starting. something like 1 mm (5/128"), which makes the handle a bit more comfortable in my opinion.

The screws that Pedder had sent along were of a much stouter type than the ones on the old saw. In addition to that, they also happened to be metric which made it a whole lot easier finding a drill that corresponded to their size.

Drilling the holes in the saw plate was kind of hard, since the steel is just a bit on the hard side for a regular drill to go through. A really good drill press helps, but I still had to regrind the drill one time. I started with a small drill, and made it up to the correct size in the next step.

Due to my reopening of the spine, the saw plate slid in place without any hick ups. 

The handle was sanded and smoothed with some steel wool, and then I gave it two coats of varnish where I wiped off the excess after each time and followed up with some steel wool to give a matte surface.

I had a feeling that the spine and plate were not completely in line with the center line of the handle. So I checked it and it seems that I was correct.

Over the total length of the saw the plate/spine bends 0.8 mm farther to the right than to the left.

This is over a length of 43 cm, so using a cotangent function I was able to establish that the angle was 0.107 degrees off to the left.

With the risk of being called a crude worker with sloppy results and no regard whatsoever for precision, I have to admit that I can live with that. It wasn't enough to get my fired up for making a new handle.

My guess is that it is some sort of optical illusion due to the grain lines on top of the handle that causes the eye to think that it is all crooked.

I tested the saw for a couple of cuts, and it cuts beautifully. No tendencies to wander off or pull to one side. But I attribute all this more to the sharpening of the saw than to the handle and spine. 

Conclusion of those two saw builds/rehabs:

Making a saw handle is not that hard. 

Making a nice looking handle on the other hand takes a long time. 

Making a really nice almost perfect handle is a lot of work, and takes a lot of time.

I think I ended up in category number two. It is nice but it isn't perfect.

The spine ended up looking fine, but again not perfect, It is not completely symmetrical but that was due to how I bent it. 

While it is possible to make a saw completely from scratch, I think that getting a kit for a first time is well worth it. I noticed that Two Guys In a Garage sells kits. And I think that there might be other ones out the who does it too. (I am not affiliated with TGIAG, but I have looked a lot at their saw handle scans page, and I would like to give them credit for making those public available)

For me the most fun is in shaping the handle. Bending the spine and filing the teeth are just things that need to be done in order to complete the saw. So I am happy that Pedder did the filing job for me.

But just because a project is difficult doesn't mean that you shouldn't attempt to do it if you feel like it. There is also a special feeling in using a saw that you have made yourself, and that has to be taken into account too.

If you count out the metal bending brake and the 25 ton hydraulic press, the rest of the project can be made with very few tools and in very little space. So the way I see it is that getting a kit is a cheap way to avoid a divorce and an eviction due to mounting a large hydraulic press. Just in order to make a bent saw spine.

Do you remember to help other bloggers?

Fueled by a casual remark from Brian Eve the other day, I revisited one of my old posts about blogging.

I read all the comments again, and I remembered that it was a long time since I had done anything in the respect of updating my blog link list.

The first new (to me at least) blog I found was by reading some comments on another blog. I held the mouse pointer over the name of the person commenting, and to my surprise there really was a blog to be found there.

A bit of looking at this blog too, and I found another one that I hadn't come across before.

The first blog is called "An Unplugged Woodworker".

The second one is "The Apartment Woodworker"

So I'll ad those to my list of blogs that are out there for you to read.
