What size capacity do you have for turning wood? Our main lathe is a J.A. Fay and Egan timber bed lathe circa 1900 of 22' in length which gives us a turning capacity of nearly 18'. We have turned column bases as large as 6' in diameter. Can you supply virtually any species of wood? We can provide every species of wood that is imported to the New Orleans area and have sourced a few species that are not common to this area, but we will not turn Pressure Treated Pine. How do I stop Wood Rot Wood rot is the most common failure of exterior millwork, especially columns, posts, and spindles. This is normally caused by one of thousands of wood molds or fungi that travel in the air and grow in moist conditions at the end grain of unprotected millwork. The number one preventative is applying a fungicide to the trimmed part prior to priming, painting, and assembly. This application is best made by soaking the bottom of the spindle, post, or column in a bath of either a zinc or copper napthanate solution for a minimum of 5 minutes. The longer the soak, the better the penetration. If soaking is not an option, repeated brushing or rolling is acceptable. Allow the solution to dry for at least 24 hours prior to priming and painting. Since the latest solutions are water based, it may be likely that a latex primer is most compatible. We prefer the zinc solutions as they dry clear and will not bleed through the paint like the copper solutions.Columns and hollow newels merit some additional comments. In humid environments we find that ventilation of the column is of utmost importance. All hollow structures will eventually build up a humidity inside causing condensation to form near the bottom of the structure. We always provide weep holes at the plinth equivalent to 10% of the inner area of the column . In addition we recommend that some ventilation be provided through the capital so as to allow air to circulate freely through the column. Why turn the old fashioned way vs. using a copy lathe? In reproducing older turning designs, we have found that the copy lathes simply cannot compare! In order to affect the crisp lines of the more delicate turnings, we use a large array of special hand held gouges, skews, and scrapers which allow us to carve all of the original profiles. The copy lathes use a single V-shaped scraper which tears at corners and leaves a finish that requires too much sanding to maintain crisp details. In reproducing the larger turnings there simply is no copy lathe large enough. In fact, there is just no substitute for skilled craftsmanship! How do I measure a post or column? In the case of extremely large pieces which cannot be economically shipped, a very good sketch with dimensions will be required. Columns can be most easily measured using a seamstress tape which is wrapped around the column at 1 foot intervals to give a list of circumferences. The intervals for measurement near the top should be reduced to every 6-8 inches. Where fluted, the width of the flute (groove) and the width of the margin (flat spot) should be carefully measured (to a sixteenth of an inch) every 2 feet minimum. The termination of the flute top and bottom will also have to be noted.Porch posts require a caliper to make an accurate drawing. Now go to the post and make as careful and proportional a sketch as you can manage. Measure and note the overall dimension of the post...width and height, then the overall height of the bottom square. From the point where the turning begins, measure up to the first obvious break in the shape of the post, such as the point where a bead turns into a listel ( the little straight vertical section typically 1/4" tall) or where a listel turns into a cove (deep indented area) or where a straight section of turning is interrupted by a series of small (1/2" to 3/4") beads. Put all these height measurements to the right side of your drawing with lines pointing directly to each break in the shape. Using your caliper, measure the diameters of each break in design. Slide the caliper around the post, then carefully lay the open caliper on a tape measure and read the distance between the two nails. On the left side of your drawing, note the diameters of each of these breaks.Another option for the heights is to use a piece of 1/4 in plywood app. 10" wider than the post and long enough to cover the entire turning and then some. Tack the plywood to the back of the post allowing 5” to extend on either side. Taking a good sliding square, you can set the square to the plywood, slide the gauge out to meet a break in the post design, then scribe a line on the plywood. You will now have an accurate series of lines to which you can sketch the outline of the design and mark down the diameters. Cut the ply wood template into manageable lengths on a 45 degree angle and we can reassemble in our shop. An accompanying set of photographs taken perpendicular to the various details will be an enormous aid to accurate reproduction. What if I don't have a design? Very often we are asked to turn parts without a full design. This is not a problem so long as we have an idea of what you want, either a picture or sketch, and a dimension for the height. We have frequently assisted with design ideas as to what may be proper for your style of construction and are happy to do so. How is shipping handled? We have shipped all over the continental United States as well as the Caribbean. Larger posts and columns will be shipped via freight line while spindles are normally shipped via UPS or DHL. Smaller orders can be shipped via US Postal Service. How much do the turnings cost? Every item will need a quote due to the infinite variety of designs, but we can give some rough parameters of cost.
