[...] 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 [...]

Of the eight with photographic entries all are of cast iron frame construction. Two of these have rounded cored ‘necks’ and necks separate from-and bolted on the-bed sections. These are the Welch, Harrison and the Welch & Chipman. Welch & Chipman saw Welch, Harrison & Co. saw The Rogers saw has a rounded cored neck cast integrally with [...]
[...] 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 [...]
[...] 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 [...]
[...] as well and may need to be repaired similarly. Me, I am planning on leaving my bed rollers below the table as is recommended by some when planing material that has already been jointed flat on one side. So I did not repair the wear on my bed rollers. Bed Problems
Owners have reported bed wallowing up to as much as 1/64” Later Parks planers sometimes came from the factory this way. Well adjusted bed rollers do compensate a good bit for bed wear or poor machining. Mine was wallowed about .005” in the centre. Since I intend to install an MDF platen over the bed, so the [...]
[...] Foundry and Machine Co.; hence, the name "Lincoln Miller." The rack feed machines did not have an even table motion and were used only for roughing-off the pieces to be afterwards filed to size and finish.
All this was changed by the even motion of the screw feed Lincoln miller, on which, when equipped with "gangs" of cutters, the then exceedingly difficult feat of milling irregularly shaped gun parts to gauge was first successfully accomplished by one Gilbert A. Bush, who also made his own cutters, which gained for him quite an extensive reputation [...]

[...] produced. 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 [...]
[...] 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 [...]

[...] Province of 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 [...]

[...] is generally understood by the term piano-miller. The main feature of all these machines is that the table is long, and has a long traverse by comparison with the tables of Lincoln millers. They are, therefore, both in their build and in the dimensions of the work clone upon them, the present rivals of the planing machines, after the patterns of which they are built.
The important questions of degree of accuracy and the smoothness of finish produced on the common planer, and on the plano-milling machine cannot be settled in an absolute manner. Differences [...]
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), [...]
[...] 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 [...]

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 [...]
[...] 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 [...]
[...] 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 [...]
[...] rest are carefully made and provided with an adjustable clip to take up all wear, and always hold the table firm. These inclines are bolted to a sliding sash-like casting, which is dove-tailed and gibbed into main frame and allows the tables to be horizontally withdrawn away from head, without in the least disturbing their adjustment. This is convenient when wishing to sharpen or change the cutters or knives. The hand wheels on side of frame hold tables firmly when in their proper position. The Front Table is 42 -inches long; the rear table [...]
[...] every second one. The expected basic complement of equipment was a jointer, planer, bandsaw, variety saw, shaper, mortise machine, and tenoner. One could work wood lots of ways and make money at it too. But at the end of the day you were a rank dilletante without the tenoner and shaper and knowlege of how to tool them up. I believe that the reason single end tenoners have all but disappeared from small shops is due to the somewhat complex nature of the tooling required to use one effectively; and the supposed difficulty with maintaining it. The machine is capable of [...]

I lay the straight edge across the infeed and outfeed tables checking, front, center, back and both [...]

[...] replacement. Missing Guide
You can see the guide on the right side of the infeed table. There should also be a guide on the other side that could be adjusted depending on the width of the board being fed into the machine (there are multiple holes in the table to bolt it in place). Of course this guide is MIA - I will need to find out (or possibly imagine) what this looked like and make a pattern to have a new guide cast. Missing Rollers

[...] into shape can also be tried. Care must be exercised to avoid cracking the cast iron however, and the table may want to gradually return to its previous shape when the pressure is removed. Your local machine shop tolerances may be greater than the amount of out-of-flatness presently in your surface. Clearly, nothing is to be gained in this instance. Things can only get worse! If after everything else that you can think of has been tried, resurfacing seems like the only option, then you will need to seek out a competent shop with a machine capable of handling your top.
