[...] woodworking shop. The “new” machine – a large, heavy-duty combination machine that consisted of a band saw, table saw and jointer all mounted on a single base and powered from a single power source – had the name Crescent Machine Company, Leetonia, Ohio cast into the base in raised letters. Later on, I would discover that Crescent called the machine a “Universal Wood-worker,” and due to its unusual configuration, it was one of the most distinctive machines ever made by Crescent. After discovering this machine, I wanted to find out as much as [...]
[...] time acquaintance from the OWWM web site, Randy Wilson of Indianapolis, IN, contacted me about a band saw that he had recently acquired. He had a lead on an old Cordesman & Egan band saw that was at an old factory that was being torn down. Knowing that this band saw was pre 1900, he wanted to rescue it and made arrangements to purchase it. While he was loading the band saw up, he spoke with someone at the property that told him that there was another old band saw [...]
[...] Introduction In the Winter of 2004, I was fortunate enough to score a nice old Delta / Crescent 12"-14" Table Saw. This table saw is considered by many to be the best saw that Delta ever made. When Delta introduced the Unisaw in the late 1930's, they immediately realized that they had a winner in the overall design of the saw. Many customers wished for a larger version of the saw so Delta took the basic design features and scaled it up to a larger 12" table saw. [...]
[...] apart, bring it back to factory fresh and put it all back together to where it works like the day the saw was born. It should be noted that even the saddest of bastards with no broken parts really only need a good cleaning to get them back to working properly. Most people, if they are going through the entire process, will elect to repaint. As the saying goes, “in for a penny, in for a pound”. I should note that this write up is based on an early vintage Unisaw. Since 1939 there have been many “value engineering” changes to the Unisaw and while I’ll try and catch each [...]

[...] price should be around $1900. Of course a 1999 ain't holding a candle to the 1939 but it's still a fine saw none the less. I have not paid much attention to the various Delta drill press lines as there were so many through the years it's darn near impossible to focus on one popular model. I also lack a number of catalogs making a drill press write up difficult. Similarly, lathes suffer the same fate. The Delta Specialty Company began business in 1919 in a one car garage at 969 Louis Avenue on Milwaukee's near northwest side. It was called the Delta Specialty Company until [...]
[...] South Africa. To this end, in 1964, he purchased a Rockwell Delta Model 1164, 10 inch Tilting Table Saw and 6 inch Jointer combination from E.W. Tarry in Johannesburg. The saw, made in Pittsburgh, USA, came complete with motor, fence and mitre gauge but without the saw guard attachment which was an optional extra. The jointer, a Model 37-220 6 inch was made by Rockwell in Guelph, Canada. The combination cost in the region of Rand 440 at the time. (Rand is the South African currency denomination, internationally [...]
[...] Its production run spans over a half-century making it the longest running production of any table saw in history. Over the years many changes have been made to the saw. The purpose of this article is to document all the significant changes made to the saw since its introduction in 1939. The base line for this study is the 1939 No. 1450 model. The order taken in this type study is roughly from top down (table to floor) and outside in. As parts were changed the intent is that the particular part will be noted [...]

Pre-History of Radial Arm Saws
During the twentieth century the radial arm saw was introduced, evolved, became a great success over a couple of generations, and then became largely obsolete. This section covers the history of circular crosscut saws before Ray De Walt's introduction of his first radial arm saw. In 1869 Charles R. Tompkins patented a swing saw. Swing saws already existed then but this is the earliest swing-saw patent we have found. Tompkins manufactured his [...]
[...] the wood at once; veneer cutting machines; moulding and recessing machines; bevel sawing machines; saw sharpening machine; tenon cutting machine by means of circular saws; boring tools.” The improvements of the present day are well known to all who care to interest themselves. Motors direct connected to high speed spindles which are run in ball bearings approach perfection and economy. Today many mills are planing wood as fast as 250 lineal feet per minute. Through the use of grinding attachments and multi-knife heads, moulded surfaces are being made of unusual smoothness [...]
[...] complete, the restoration process could finally get back into high gear. The bearing were mounted back on saw and the wheels were installed. The upper bearing assembly installed and ready for the wheel Lower bearing assembly ready for wheel and pulleys (shot from pulley side) 1.2 - Installing New Tires The next step was to install new rubber tires on the wheels. Rubber tires are necessary so that the band saw blade does not ride directly on the cast iron wheels, which would result in the metal wheels wearing down over time as the [...]
by Doug Westlind Twice in one week I was asked how I balance band saw wheels so I thought I would write something up on the subject. Balancing of the wheels is important on all band saws but it is essential on larger and higher speed saws. I have tried several other methods and none were completely satisfactory. This method is what I have settled on. It works very well, is easy, is done with the wheels on the saw, and doesn’t cost much. The tools needed are a dial indicator with a magnetic base, self sticking lead wheel weights (1/4 ounce), [...]
[...] patent was lost in the 1836 patent office fire, and so far we have only the patent title ("Band or belt saw") plus a description written by a magazine editor who confessed himself as "little acquainted with machinery in general". He describes a conventional two-wheel vertical band sawmill; no mention is made of blade guides or how the blade is tensioned over the wheels. An example was built by R. French, a millwright from Morrisville, PA. Stewart offered to license his patent and French offered to build the Stewart patent sawmill to order. There is nothing to suggest that [...]

LUBRICANTS AND LUBRICATORS FRICTION AND LUBRICATION Since the earliest times a great many engineers have been seeking earnestly to discover some means for eliminating or at least reducing the friction in machinery to the lowest possible amount, while other engineers have been bending every energy to find some means to increase it for certain purposes. Thus it must be evident that friction has both good qualities and bad ones. It is true that friction has been called the highwayman of mechanical energy and many other names equally as reprehensible, [...]
[...] “American”. Machines can also be double badged such as this No. 1 planer. And as in this No 4 Band Re saw, with this on the base and “American” on the column. Another variation is a bolted on “American” and the original designers name cast in a main part of the machine. The dual tagging is much more prevalent on the earlier machines slowly having been phased out as American Established themselves as a name. Second is the Angled badge: This badge is can be in several forms and is the indicator of where the machine was actually made and not whose design (of [...]

2 - Centralized Lubrication Systems This section is based on a write up in: Machinery's Handbook , 11th Edition. 1943.
Various forms of centralized lubrication systems are used to simplify and render more efficient the task of lubricating machines. In general, a central reservoir provides the supply of oil, which is conveyed to each bearing either through individual lines of tubing or through a single line of tubing that has branches extending to each of [...]

[...] was the last great exposition in which the Whitney machines were exhibited. The following few years saw introduction of a large number of new Whitney woodworking machines. The Silver Medal Planer 1866-1878, was used in lumber surfacing. Somewhat later the P-1 “New Whitney” Planer, 1878-1892, was built. This planer was the first to incorporate a chipbreaker mounted to swing concentrically with the cutterhead.
