The modification to the towing post to enable it to be used for proper towing
is based on the unit 'Paul Freshney' built and describes in the
Model Slipway "Wyeforce" Kit review in Model Boats Magazine December 1996.
The brass tube used for the main central unit is approximately The same diameter
as the white metal and wood dowel supplied (in the kit). being 5/8" OD.
I used the KS Metals brass tube No: KS143
The Outer tube fixed to the hull being KS: 144 (21/32" OD),
The 143 being A sliding fit inside 144. A bolt was used to lock the two tubes together. The supplied white metal cross pieces (shown dark blue) were used,
but I first drilled a hole through them for the clamping threaded rod (red).
The two outer vertical posts can either be 'as supplied' or use 143 brass tube.
The complete assembly was fixed together with slow setting (2 hr) Araldite,
By using slow setting adhesive it is possible to check everything is aligned
before the adhesive sets.
Once set and cleaned up the actual swinging part of the tow post was fitted as normal. The lower (144) brass tube is splayed at its bottom end
and glass fibre tissue/resin used To fix to the hull.
I also reinforced the deck where the tube passes through it,
by adding a wide deck beam across the hull.
The two outer vertical tubes simply drop into holes in the deck and fixed.
The holes being blanked by plastic sheet underneath.
When towing I put a cord JUST round the centre vertical post (brass tube),
with a large loop, which I find works well, the swinging tow arm
just moves freely.
