Semi Circular Bench Plans
Feb 21^st, 2008, 8:41am

I want to make a semi circular bench to fit into a walled part of my garden. It would be almost like the sort of thing you find for going around trees but reversed.

My carpentry skills are limited - as in I can cope with mortice and tenon joints but prefer not to Undecided

I am also thinking that it will need to be made in a series of flat sections (hexagonal) rather than a continuous curve.
Any suggestions as to where I might obtain plans? Also what timber would be best for outside use?

Thanks

Hi

What is the radius you what the bench to fit ?

I would say you have the choice of three timbers Teak, Iroko or cedar all have natural oils to keep them in good condition. But you can also consider European oak or pressure treated soft wood.

Regarding construction the back and front rails could be laminated from strips of your choice of timber. And regarding the number of segments that depends on the radius.

Let me have the radius and I will do a quick drawing for you to consider.

Many thanks - the area is shown below. It has a 50 inch radius but is not a full 180 degrees.

Please excuse poor drawing - I am a bit rusty.

Asuming its fabricated from mild steel then the best finish will be to get it hot dip galvanized. This can be left as is or have it powder coated or treat with a proper primer for galv metal then finish paint with oilbased paint.

Thats a very tight radius for the angle at the front of the seat, may be better to carry the flat of the back along the seat and weld to a 40x3 flat to make the angle.

Hi

Yes it is proposed to use Mild steel as stated in the notes

I would presume the fabricators would remove one leg of the angle, form the radius. Cut to shape a piece 3mm plate to suite and weld it in position. But its down to the steel fabricator to make his or her recommendations on the fabrication techniques.

Regarding the finish would Hammerite – Hammered finish give a rustic look say in the dark green?

.

The wall seems to be well built 9" with a top of Engineering bricks on edge. The curve I would assume would give a greater strength say than a straight wall of similar construction.

I am open to advice.

One benefit to me is that if the supports are painted say a dark green then the bench will appear to float in space.
