    Can't get relative coordinates to work.

    There is an option, probably in Options, User Preferences to have user input over-ride snaps and other automatic types of input. Joe Agro joea@autodrill.com http://www.autodrill.com Please pass by our website.

    Revision control of parts/assemblies

    Why not work the revision history in reverse. I.E. Save the oldest version as PartName and PartNameOrig. Save next oldest version as PartNameA. Use PartName in the assembly. Save the Latest ALWAYS as PartName. Now the assembly will always update. If older assemblies are needed use the latest...

    1 Phase Motor on 3 Phase Power?

    You may have a capacitor problem or the 205V is too low to start the motor. Why not consider using a three phase 208/230/460 Volt motor for the compressor. This will probably require a new motor starter to cycle the compressor on/off with the pressure switch. Once the conversion is made,future...

    Milling Keyways on shafts

    Climax makes a portable milling setup which may be useful if the actual rigging of the shafts is the problem. Another suggestion to handle the multiple diameters is to make precision shims to go under the V blocks to easily level the different diameters. Some type of key or pins in the bottom...

    Small Comercial/Industrial Moters

    Many small commercial motors bypass the standard NEMA rating and use momentary peak available HP for the advertised rating. Look at the "Cheap" compressors available from companies such as Harbor Freight that sell 6.5HP compressors for $400. A good industrial motor alone is close to...

    ID Fan efficiency questions.

    Regarding the power factor of the motor. Assuming it an AC Induction Motor, then it definitely is not a constant or almost constant. It is very low at low loads and improves as the load on the motor increases. For this reason, it is usually best to size a motor close to the full load...

    Replacement Steel for AISI 1144?

    I would definitely look at 11L41. It should make a significant improvement in machining with almost no drawbacks except a slight cost difference. It is widely available.

    SPARE PART WEB SITES

    The closest thing available is probably the Thomas Register.<br> Their site has a nice search engine based upon vendor name or product.<br> Other sites that may be helpful are:<br> W.W. Grainger<br> McMaster Carr<br> MSC Industrial<br> <br> Regards...Joe

    difference

    Pipes are made to industry standards. Diameters and wall thickness has been established for many different pipe sizes.<br> Tubing can be of any size and wall thickness. Only the need will dictate the availability of a tubing size.

    Mechanical movement

    Torque limiters are also commonly found built as a part of a machine coupling/drive element. The device will drive or couple two parts up to a given torque. At that point it will either "slip" and maintain the desired torque level or disengage. Controls are necessary to effectively use these...
