My blog consists of all things wooden and engineering, as my career as an mechanical design engineer was coming to a decided end and the far eastern mechanisation was looming and removing ones ability to stay in the arena, I decided it was time to make a few new directions in life.

Those directions were to gather as many of the traditional skills as possible before the starvation of the hand to eye coordination that was now driving those hands dissapeared before our very eyes.

Having already made a myriad of different things including spinning wheel and traditional wooden wheelwrighting and traditional wooden tools, I embarked on a future using the skills set gained over several decades. The Chevalette marquetry arena is one I feel I need to futher enhance using alternatives.

My journey has been rich in others willing to teach this oldish dogs some new tricks which has saved me many thousands in retail therapy. I have used the skills to get the things needed done, others now realising what the high tech future has created, need to work fast while the real life skills on offer are still being shared.

In my blog are many items that I have made for myself over the last 25 years, using the skills gain from many of the old masters themselves. Skills like the wheelwright which I now use for traditional wheelbarrows and carts etc.

I am also a fully time served traditional shoe and boot maker with a full electric free workshop, doing thing in the ways of old, including making the bespoke wooden lasts, and traditional clogs.

At Wooden Engineering we consider any challenge with an open book and would try anything once.

Over the last couple of weeks I have been building a copy with a few of my own mods this Victorian era piercing frame or donkey saw.

I got the idea after seeing one in use on the series of videos called hands a superb set of 14 DVD’s of all the old crafts to be found in Ireland, my faviorite the Shannon Class sailing boat maker and farmer Mr Fury.

Back on topic, The frame saw I have made uses a frame and blade that slides up and down via a full width foot peddal situated at the front of the main frame which is powered by one or both feet.

The foot board pivots towards the rear end of the board so the action is one of a forward push down with the front of the foot and there is still enough rear leverage to assist the springs that pull the frame back upwards again.

The foot boardconsists of an inch thick board with a full length 2 by 2’ batton screwed to the underside about 3/4 of the distance from the front edge, it pivots on two bronze olite bushes drill into the center of the cross baton and fixed by two plain steel pins from the outer sides of the frame feet see pictures.

The two end pivot bars are themselves secured by two brass plates that are secured by an allen bolt threaded into the rod itself and then a brass crew into the timer to prevent it from moving.

More to follow soon.

The rope seen here is weed whacker starter cord, this is fastened to one side of the cutting frame bottom rail and travels through two nylon pulley’s which are fitted into two routered slots and secured with a wooden dowel, the cord then returns up the opposite side to the lower bar on the frame.

If you try to use two seperat cords they have to be exactly the same length or the frame can jam which i soon found out, so a continuous ford and pulley’s balances out the motion with each press of the foot board.

The upper frame is made from 3 X 3” ready planed stock, this has a 2 X 1 inch rebate removed for the frame and guides to sit into afterwards, the top rail is 3 X 2” and through tenoned into the rebate.

The main table is 40 inches high and made from 3 X 2” lumber

throughout with the exception of the two foot rails.


The table top is in two halves and fitted over the top with foam board which has a central cutout which can be changed if damaged, this opening also accomodates the lower blade holder when changing baldes.

The blade frame is made from 2 X 1 and measures 14” deep and 33” wide to fit inside the to frame.
The blade holder is made from 3/8” square steel bar which is morticed into the middle of both top and bottom rails.

The lower blade holder is drilled to take a washer and bolt to prevent it from being pulled through the rail.
The top blade holder has the same half joint nut and an added adjuster in the form of an outer tube, washer and wing nut, please see pictures.

Showing upper blade holder with its outer tube setup which draws the blade upwards to tension it.
The last job needed is to fit a bellows to keep the vision clear whilst working, I will show how I do this soon.

Forgot to mention the two 8” springs that return the frame each stroke and the two 1” X 1” guides that secure the cutting frame which guide the frame on its stroke.
When the cord and table have been removed the sliding frame can be slid upwards and outwards without removing the guides.
The redfoam board can be bent so it fits in between the frame quite easily.
The beauty of this donkey is it gives you both hands free to hold the veneer packet and can accomodate quite large sections.

This type of tool is to my own design from a video and can be made to any size you like really, if I may have missed something just holler and I am willing to help.
