RESEARCH EVALUATION AND SELECTION OF: Design Modifications – The specific design of this particular prayer table is comprised with 3 sections; top face, turned centre and legs. Its constructed by 6 components of wood; 1 for the top face, 1 for the securing plate which is placed directly centre underneath the table top, 1 turned centre which acts as a beam support and 3 single pieces of wood which are legs connected evenly around the bottom of the centre support by screws. Decorative aspects of the table top is that it has a routed finish around the top face of the table, the centre support is lathed for a sculpture look and it finished with a decorative finish. Materials – There are a variety of materials both woods and tools required throughout this project to have a successful completion. There are 3 different woods needed for each section of the table. The woods and sized required are: ALL MEASUREMENTS ARE IN MILLIMETERS. * Table top: Wood - Hoop Pine – 90 x 19 x 4/360 (WxTxL) * Securing Plate: Wood – Ply Wood – 120x120 * Turned centre: Wood - Meranti – 65x65x450 * Legs: Wood – Meranti – 260x70 There are several materials needed in the process of this Prayer table. Screws are needed to connect pieces together and ensure a firm hold together. Two screws in each leg to be screwed into the turned centre and 4 screws to connect the securing plate to the table top. Also PVA glue is needed to assist joints and give them a firmer hold. Tools and Equipment – * Try square – used to ensure that cutting lines on the wood were accurate at 90 degrees. This makes the project look professional and precise. * Steel Rule –To ensure markings marked on the project were accurate to required measurements. * Tenon saw – used to cut the wood into measurements from the plan which was given. * Marking Gauge – used to creating a mark on the turned centre so when planning I didn’t plane past the mark * Jack Plane – Once the marks were set in place along the turned centre the jack place was used to cut out an accurate 45 degree angle on all four of the top edges of the base wood. * Protractor – was used to create the specific radius of the circle along the side face of the turned centre wood. This was done to create a planning path and know where to stop. * Coping saw – once the marking of the legs was correct the coping saw was used to cut out the legs following the markings. * Half round Rasp – used to mend uneven edges and make them accurate and to level. * Half round file – after the half round rasp done its job the file was used to clean it up and make the particular smooth again. * Drill Press – used to produce a hole through the legs in order to be able to be attached to the turned centre by being screwed down. * Electric drill – used to fix legs to turned centre of wood. * PVA Glue – assisted the screw to build up a more secure hold. Components – Once Brocken down, there were 3 structures that consist within the project; top, middle and bottom. The top, meaning the table face, the middle meaning the turned centre beam and the bottom meaning the legs which hold the table up. All three structures are constructed differently which contain different process, materials and tools. TOP (table top) – The wood required for the table top are 90 x 19 x 4/360 pieces of hoop pine. A portable router was used in order to cut out the joints which were then used for the connection of the biscuits. Pre cut biscuits were used to connect the 4 pieces of wood together in order to create 1 piece of wood which then was marked out by a circle 360degrees with a 350mm diameter. MIDDLE (turned centre) – The wood required for the turned centre is one 65x65x450 piece of Meranti. The tools used in order to complete this particular task were a pencil, protractor, steel rule, jack plane and a lathe. BOTTOM (legs) – The wood required for the legs are 3 pieces of maple with the measurements 65x19x260. The tools used in order to complete this particular task were a pencil, steel rule, coping saw and band saw. Processes – TOP (table top) – Stage of process and steps of construction: * First of all we cut out 4 pieces of 90x19x360 hoop pine. * Once all 4 pieces were laid out correctly we then marked out were the joints were going to be cut out. However we had to make sure that the joints were not marked near the edge of the project other wised when we cut out the circular table top the biscuits would be cut through and this will increase risk of joints snapping * Once the four pieces of hoop pine were cut out to size we laid them out the first and third alternate in grain direction to the second and fourth. This was to ensure once glued and fastened together the wood would then not turn or bow. * Then once we had ensured opposing woods grains were alternate were places the biscuits into the joints with glue and fastened all four pieces together in the sash clamps. Once that was done we put waits on the corners and middle to ensure bowing or bending wouldn’t occur. * Once it was dried we then marked out a circle with a diameter of 350mm ensuring we came in 5mm on each edge to make the diameter 350mm not 360mm. We then cut it out on the bandsaw and routed the edge. MIDDLE (turned centre) – Stage of process and steps of construction * First of all we cut a piece of Meranti 65x65x450 * In order to lathe it effectively you first have to make sure the corners of the piece being lathed are not 90 degrees but rounded first. * So we marked diagonals on the face edge of the centre column to identify centre point * Then a compass was used to create a circle * Next step was using a plane to create a cylindrical shape. * Once that was done connected it to the lathe and shaped it down to the correct requirements BOTTOM (legs) – Stage of Process and steps of construction * First of all we cut 3 pieces of 65x65x260 maple * Then we marked it out and draw the shape given to us on the plan * We then used the band saw to cut the shapes out and half round files and rasps to smoothen the side corners out. CONSTRUTING (putting together) Once all parts were cut out accurately according to the plan it was then time to assemble the project together. In order to attach the table top to the centre column it would have to be done by attaching the securing plate to the table to via 4 screws in each corner and to the centre column by 1 large screw directly down the centre of the column. Also in order to attach the legs to the centre column it was drilled in with 2 screws in each leg into the lower section of the column.
