Timber Quality
Several different combinations of timber
would be acceptable provided the components shown as A, B, C and D
are sound, and are relatively free of strength reducing
imperfections such as large knots, splits, etc. You may prefer to
use Appearance grade timber.
Consult your TABMA Timber Merchant (or your local equivalent)
concerning availability of stock, dressed-all-round (DAR) timbers,
seasoned or unseasoned, at least of structural quality. Some
suppliers may be able to dress material to-order.

Step by step instructions
Step 1
Cut these from the 75 x 50 mm DAR.
Note Dimension shown for C should be equal width of seat made up
of two widths of parts E.
Step 2
Cut these from the 200 x 25 mm DAR timber.
Step 3
Cut these from 75 x 25 mm DAR.
Note Dimension G should be equal to width of Part C.
Step 4: Assembling frame
Bolt pieces B and C to centre board
"D" as shown. Use 50 mm x 6 mm cup heads bolts, nuts and washers.
Head of bolt must be on the top side of D. Ensure that B and C are
at right angles (square) with D. To make a stronger joint use a
standard PVA wood glue on these joints.

Step 5: Fitting wheel brackets
Fix axle brackets to Part A
and B, using screws/bolts as appropriate. Heads of bolts must be on
the top side of Part D if used. Front wheel brackets must be
positioned to allow rope holes on the forward part of Part A and so
located that the axle position leaves pivot bolt and nuts accessible
for adjustments.

Step 6: Assembling steering
Attach pieces, Part A to Part D
using the 115 mm x 9.5 mm hexagonal bolt with washers and nusts as
shown with locking nuts on top of Part D (first check that hex head
clears axle, you may need to sink nto bottom of Part A.
Steering Lock
(Part J) Screw block for the steering lock
Part J to the underside of Part D, 30 mm behind Part A, using the
two 38 x 3.15 mm wood screws. Thread Rope through holes in front
edge of Part A and tie double knots on the underside of A.
Step 7: Fitting seat
Nail the seat boards Parts E, on the
cross braces, Parts C and B, such that the boards cover top side of
Part C, fitting flush with front edge and side (or ends). Use four
nails per board fixing firmly to Parts C and B. Nail sides (Parts F)
into the edges of seat boards and into the ends of Part C. Note the
cut-outs on side Part F are sized to fit closely over Part B. Use
four nails per side. Nail seat back, Part G between sides F. The
position of the seat back should be adjusted along the length of the
side depending upon the size of the drivers. Use two nails each side
of seat brace, nailing through side, Part F into ends of seat back,
Part G.

Step 8: Assembling wheels
Slide larger diameter wheels on to
rear axles, with metal bush to the inside, or use washers as shown.
Finally, insert split pins and bend open. Repeat procedure for front
wheels.
Step 9: Fitting footrest
With wheels fixed, position the
driver on the seat then locate the footrest, Part H onto the top of
Part D. Use two nails to fit the footrest in position.
10: The final step
The final step is to round off all sharp corners with plane or sander and finish
all over with your selected paints.
