I am planning to make another set of planing forms - the first set I made were done following the Thomas Penrose layout and I have been pretty happy with the forms overall.
Reviewing the details to refresh my memory I looked at the Waldron layout which has the dowel pins close to the push/pull bolts rather than centred between them as in the Penrose layout. Sometimes I have noticed a slight binding of the dowel pins when making large adjustments such as setting out the butt side and wondered if the Waldron layout might reduce this at all?
It is not surprising really given that the forms are flexing slightly between stations - and with the pins bang in the middle of the "flex" at times this is what must cause the slight "creaky" binding of the pins.
Is there a preference for dowel pin positioning or is it just down to personal preference?
The forms I am planning will be at 6 inch centres as I have a lot of old English tapers which are all given at 6 inch centres and figure a second set of forms will reduce the "faffing" involved in interpreting these tapers for 5 inch centre forms.
I also like making stuff so it will be fun as well.
