Amelia Squariel: Square Four Toolkit

After all this work on W/NG tool kits it is about time I paid a bit more attention to the kit on my Square Four, which has served me well for several years. Before we get into that, here are a couple of excellent examples from club members:

Here's Scott Williamson's 1949 tool kit from the Square Four belonging to his father. The tool roll should be a 6640-46:

Scott Williamson's 1949 Tool Kit

This is not a Square Four tool kit as such, but belongs to David's 1949 VH so is a similar period to my 1951 Square and shares some of the tools.

David Andersen's Tool Kit

Currently my own tool kit looks like this:

It's in pretty good shape, having been used for maintenance & repairs for a couple of years.

As you will know, until the early 1950's Ariel parts lists were conveniently illustrated. This is the last Square Four list that was illustrated, from 1949:

Here's the tool page from my 1951 parts list

The 6607-39 single ended spanner is the only deletion between these tool kits; the later list includes the tools for the QD rear wheel. Note that they both identify the 6640-26 tool roll which is a mystery, since the later civilian tool roll (6640-46) appeared in 1946 - the illustrated list gives the game away though, because it has the 6640-26 roll in the list, but the 6640-46 roll in the illustration. The entry in the list is obviously a typo.

The QD rear wheel tools are illustrated here, in the 1947 singles parts book:

Here's a list I made a while ago, to collate what I had. Decimal dimensions come from the factory drawings in Ray Tolman's list.:

So here are the tools:

Item 1 G1/125 Open Ended Spanner

Item 2 G1/110 Spanner for brake fulcrum adjustment

Item 3 G1/59 Double Ended Spanner

Item 4 is slightly odd - not made for Ariel, but modified by or for them. It has the original makers name ground out and 'Ariel' stamped in its place; it also has the sizes in BSW form.

Item 4 G1/124 Double Ended Spanner

Item 5 G1/66 Double Ended Spanner

Item 6 G1/55 Double Ended Spanner

Item 7 G1/55A Double Ended Spanner

Item 8 G1/102 Clutch hub nut tube spanner

Here's one I made earlier:

Item 9 Spark Plug spanner

Here's a real one, courtesy of David Andersen; along with a real tommy bar and a hub locking ring spanner. As you can see, mine is not too bad.

None of the tube spanners in my SQ4 kit are genuine - they are modern or old spanners of equivalent size.

Item 10: This does service as the G1/99 wheel spindle spanner

Item 11: Modern tube spanner pretending to be a G1/122

This is the clutch centre pin box spanner that currently graces my W/NG tool kit - I only have one of these:

Item 12 - Clutch centre screw spanner

This modern one does the job:

Here's my tommy bar - just a bit of 5/16" rod. Note that the real one has two steps - the smallest one is for the hole in the front wheel spindle, and this is not the same tommy bar that appears in earlier tool kits:

Item 13 Tommy Bar

Recently I turned up a tommy bar to the Ariel pattern Here it is, with a W/NG one alongside:

I've asked Acme Stainless about making some reproduction tommy bars.

Item 14 G1/94 Ring Spanner

Item 15 G1/103 Ring Spanner

This is the tappet adjuster spanner - unfortunately I only have one of these at the minute and that is in the W/NG tool kit. I guess I will have to make a copy.
