Continuation of the last batch of No 982 planes
 
 


 

There are two reasons that I use the surface grinder a lot; the main one is for the precision and also for the nice textured finish. This usually means that I visit the surface grinder several times during the working of the plane as no matter how careful I handle the work pieces they seem to break out in a ‘workshop’ rash very quickly.

This picture here is the sides being ground true after the drilling and tapping. This also leaves the bottoms a true uniformed width and square.
 
 


 
Of course the time comes when the toe of the plane needs to be separated from the rear end. I can lose a lot of sleep here as mistakes are so easy. Any mistakes here will cost me dearly.
 
 


 
With the front and back ends of the bottom now separated each part is then milled to size and angle.
 
 


 

 
All my marks are stamped with my fly press which I couldn’t exist without. The No 982 plane is stamped with an edition and its number, the plane type is stamped on the front end of the bottom (just behind the bun). The HOLTEY logo is stamped on the inside of the right hand side of the plane.
 
 


 
The 55 deg milled bed is surface ground maintaining the angle to precision. This picture may be a little blurred but I wanted to catch the sparks.
 
 


 
Now the front end. I use two angles here. The one being ground here is the critical one because this is going to be the mouth of the plane. This is in a similar tradition to some of the wooden planes and is much easier to regulate a small aperture as desired by some.
 
 


 
This angle here helps to provide a better means of escape for the shavings and access for cleaning. The grinding here is mainly cosmetic.

These are the front bun chairs and once the blanks have been cut and trimmed up true to uniformed size the central fixing hole is drilled whilst still in the lathe. They are then tapped with an 8 x 1.25mm thread; this is for the bun screw.

The 3 x 6mm fixings are drilled on a manual milling machine using an indexing head as shown.
 
 


 
With the three index holes now drilled I only need a tool change to tap these three holes whilst still in the chuck.
 
 


 
Now that all my fixing holes are complete it is back to the lathe to form a small spigot where the bun in engaged.
 


 
The last job on the chairs now is to finish the bottoms to the 15 deg offset to the front buns. A small fixture has been made for this purpose. The chairs are mounted with the three bolts.
 
 

 
The chair is held in its fixture and secured on the saw for cutting
 
 


 
Whilst the chair is still attached to the fixture it is clamped onto the tilting milling vice for surfacing to the desired dimension.

The final part of the A6 construction.
 

Drilling and countersinking frogs for the rivets.
 

The bottom has been slotted out for mouth and drilling for the corresponding  frog rivets.

Adjuster components for A6
 

This item is most commonly known as the banjo and it is the most work intensive component in the whole plane.  This picture shows that it comes out of a round bar.
 


 


 

 There is a lot of preparation but this is not a step by step instruction manual, it is just a few snapshots.  In these pictures, after lots of preparation I start to ball generate the round part of this component.

A6 Part 2

*************
 

All of the woodworking has its edges squared up on the milling machine as I have a bit more confidence in this machine than I do a planer.

 

A pair of infill sides being drilled for riveting spacers. At this stage all edges are trued up

 

This is the infill side with the spacers pressed through the handle testing for fit. The two sides have yet to be separated.

The last batch of A6 planes part 1

After receiving a commission for an A6 smoother I decided to make a batch of six. The A6 is probably the most time consuming of the infill planes (well perhaps the A7 is worse!). When using the designation A6 one should realise that my A6 is not to be compared with the Norris or any other plane of this type – it is made to a higher precision and has some innovations not seen in the original. This standard is beyond the scope of those without a tool room; I am not aware of any comparison. I work from a reasonably equipped tool room; not a production line. All work is done in house with the exception of heat treatment for the blades.

Although this model has been blogged before I am running it through again as this A6 is just that little bit more special. I always try to make the current plane better than the preceding one. Also these will be the very last Holtey A6 planes. For all my innovations and upgrades my work is veiled by the Norris history and I feel it is time to move on.

************************

The first part of starting the plane is to get the timber chosen and prepared so giving the wood some time to settle whilst making a start on the metal work.
 

Here is a stunning piece of Cocobolo (Dalbergia Retusa) which was cut from a very nice log that I acquired from Timber Line a couple of years ago – thanks to a friend who spotted it on a visit there. This is the basic roughing out for the infill components.
 


 

With the wood put aside to rest, a good starting point is the blades as they need to be sent away for the heat treatment. This shows the milling of the faceted end and slot.

After the completion of the No 982 smoothing planes it was not long before I was pressed into making a larger version in the form of a panel plane.  Because of the enormity of work on this plane I have decided to make only 8 for this batch. 

 For the benefit of those who have bought this plane I would like to blog the making.  Hopefully it will show up some areas I did not cover on the smoothing plane blog.

 You will notice that I do change my techniques from time to time.

 I will start this blog by documenting the work on the lever cap.  I would like to emphasise the work that goes into this one component.  Though I have used castings in the past for my lever caps I feel more in control by making them from a solid bar and I produce a far better product.  I  now understand why some of the Rolls Royce cameras bodies are made from solid billets.

Starting with a bar of naval brass I go round and machine all the sides true, just like you would with a piece of wood.

If this was a piece of wood the next stage would be to machine a form i.e. either with a spindle or a router.  In the case of metals I have to concentrate more on work holding so this picture shows me setting up three vices in a line.  The bars I am working are 18 inches long and cut 8 lever caps each.

I have just found this blog entry for No 982 smoother that I forgot to finish.  As it is very similar to the blog entry for the No 982  panel plane 14 1/2″  I have already done this week I thought I would just publish the pictures with no comments.

A few more pictures to conclude the subject of polymer.  Feel free to comment on whether it is worth it when you have seen the finished product. 

Hopefully this plane will be on exhibition at the WIA conference next month with The Best Things.

As you can see the polymer is worked in the same way as wood and the shaping is all done by hand.

Another view showing the fixing recess.

A6 dovetail infill smoother

It was always my intention with this blog to show how much work goes into my planes and I hope that the format I have chosen has been successful as I don’t have much time to talk about my minutiae of everyday life and just stay focused on the work in hand.  I am sorry that my postings are so random but as they are time consuming I cannot afford to put them before my work.  I hope that you can see that my workshop is a serious workplace.  I have difficulty finding time for travelling to tool events.  I know this makes me seem a recluse but I can assure you that plane making to me is more than a full time occupation.

Sorry there has been such a gap since the last posting (and the time before), but any spare time I have had lately has been taken up with visitors and I have had to make some effort in my social life.   If anyone is thinking of visiting you must be prepared to climb a mountain as this is my relaxation.

———————————-

The prefix on the smoothing plane is almost irrelevant as the techniques are the same.  I feel that there are a lot of pieces missed out and this post is to try and fill the gaps.  I will also try and fill in any gaps on the No 982 next.  Then I will move on to new projects. 

The A6 is the only overstuffed plane in my range and is one of the main difference to the A13.

Sometimes it is nice to photograph components at this stage as it is an insight into some of the work.  Once everything is assembled it is gone forever.

As you can see here that the rear infill is made up in three parts.  In the second picture you can see the three parts assembled showing the brass rivet spacers/sleeves and the recessing for the sides and adjuster.  Also the adjuster fixing bar and the handle spine.
