Chariot Plane

I find that I try to avoid using the term A28 because there is a lot more here than on the original A28 plane. These six are the last I will make as the cost of making is too high.

One of the original A28 Norris planes was sold at David Stanley’s auction Sept 2014 for £8,000 (+ commissions). In the light of this my price of £4,800 is very reasonable, especially as my plane is far superior in quality and construction. Who knows what these will be worth when I am gone.

There are some who would think that because this is cut out with a CNC mill there is no work here, to them I say “make one” :-) There was a lot of work to get here and still a long way to go. (all finished now – look out for the next project).

It has been a long time but the Chariot Plane is now finished. I have some No 983 planes to complete and then I am moving on to something new.

Despite having some part made infills which had been drying for 20 years, I decided that I preferred this piece of rosewood (which has also been in my workshop for a long time, and I have very little left) – Dalbergia Cubiquitzensis – it has more ‘bling’ :-)

I am in the process of making a small batch of these planes, which will include this rosewood, Boxwood and a mystery wood – photos soon.

I am occasionally asked how to dovetail. It is a bit of a cheeky question and it would take me several months or more full time to teach this properly. Sometimes people seem to forget I am running a business.

I have been making dovetailed planes for over 25 years now and I still keep trying to improve my system. Another plane maker described my dovetails as made on the CNC and are very cold and clinical – is this how one would describe a precision job? Then guilty as charged.

Here are some photos of part of the dovetailing process.

Sometimes it is frustrating that I have to do this much work before closing a plane up. The pictures above show a Boxwood spacer which supports the sides whilst peining the dovetails. Sometimes I use aluminium for this process but as I am only making 6 planes it doesn’t have to do much work. Also the sides of the plane will not be scratched when removing the spacer. A lot of work for a piece of tooling which will be discarded after six uses.

Showing everything in place ready for clamping in the vice. Note that the clamping plates support the dovetails as well. There is no movement and everything stays true to size.

This is the first stage of peining. You will see that the peining looks quite messy and untidy as I am stuffing the extra brass into the voids.

The last stage of peining the dovetails is the sides. Again the assembly is clamped in a precision vice with a spacer plate between the uneven peining on the underside so true reference is maintained.
 
The use of bimetals will show up any untidiness.
 
Easy isn’t it :-)

Progress on my A28 Chariot Plane

Holtey A28

This picture shows some idea of all the work that goes into this plane. Unless you have done it yourself you can never imagine the effort and thought that goes into making this Chariot. This plane is made to a standard light years beyond its original counterpart made by Norris.

During the working of this A28 plane I have been neglecting this blog but now I am ready to update which I will do over the next few weeks.
 
 
Holtey A28 f
 
All the sections I use are cut out of stock material and brought down to size, by sawing and milling.
 
 
Holtey A28 g
 
As most of my working and setting out depends on a high degree of precision (which has never existed before) surface grinding in the early stages allows me to achieve my goals.
 
 
Holtey A28 h
 
This picture shows the edges being ground. This is also important to have a true pinch dimension. I need this for the dovetailing.
 
 
Holtey A28 b
 
Jigs and work holding fixtures are also all made to precision. After much preparation work to the brass, similar to the steel work as described. Then rivet positions are drilled and I am able to screw these sides with purpose made bolts to the fixture for profiling and chamfering.
 
 

Holtey A28 c
 
After routing out the profile then the chamfering is completed whilst the sides are still jigged.
 
 
Holtey A28 d
 
Just overall set up pictures.

Here are the some sides already milled and some pre-prepared waiting for profiling.

This Chariot is the last item in the series of low angle planes I have been making recently. I have only made a few of these planes and that was a long time ago in my early days of plane making. Then my side profiles were cut by hand and I made up a template which I would scribe round. Now that I CNC these the machine can’t see my template so I have had to re-draw it showing co-ordinates to write a programme from.

This line drawing by today’s standards might look a bit primitive but I have never had the leisure to learn to use a CAD. With a drawing showing contours I can write this in to my control unit. Drawing contours is more instinct than anything and I just know when it is right however long it takes (I would be ashamed to tell you how long these ones took).
