Thread: Looking for rectangle metal bar
03/10/2017 21:03:19

Here near my shop is a dealer that buys redundant metals of all sorts and resells them at a price less than a third of the cost of new, isn't there metal mongers that do the same over by you guys?

Thread: 4" x 6" modern Belt/Disc sander motor
11/08/2017 18:28:30

Note that the core laminations of chinese motors are mostly recycled steel and very seldom proper silicon iron is used for making cores. This results in poor performance and to make matters worse aluminium (loominum)wire is used as well which does not have the same electromagnetic properties as copper. The company that our business uses for rewinds absolutely refuses to rewind these motors. One can usually judge by the weight of any motor what the quality is. Some info from the winders: 50 hz x 60 sec x 2 = 6000 . 6000 devided by the number of poles times pf = rpm. (friction & other losses excluded)

Thread: Speed of 4jaw chucks
09/08/2017 19:55:04

i worked on a Antonio Anselmi lathe with a 18in. 4 jaw, and on the machine is a warning notice "max speed on the 4 jaw chuck 270 rpm"

Thread: Variable Speed RF45 Clone or Geared Head?
05/08/2017 20:34:42

Table looks light and flimsy, geared head nice but are gears hardened & ground or plastic / fibre? 2.2Kw motor for a R8 spindle nice and strong, Rather go for Bridgeport

Thread: Cleaning acid etch primer off brushes
05/08/2017 18:59:00

I do what Andrew J does. Thinners, paint remover and cleaning agents are to expensive to waste on relatively cheap paint brushes, not to mention the waist of time cleaning them.

Who are these attackers, have they been identified?

Thread: What's causing these bands on a turned rod?
16/06/2017 19:08:29

I've encountered this effect too some time back on my Chipmaster which had two matched driving belts and after removing one belt the problem went away. They were shaking when the machine runs. I assume that there must some uneveness in multi belts that cause a "tuned vibrato" or harmonics that carries this over to the cutting tool. I noticed at the time that the banding varies in broadness and intervals at different speeds and od of the work.

Thread: Brown-out Protector project.
10/06/2017 19:53:48

From time to time some gimmicks appear on the market, i have confidence only in the proven products that served industry for many decades, I refer to a simple unit that plugs into a 11 pin base which is adjustable for the percentage of protection required, over volt and under volt. A sales person once tried to sell me a REVOLUTIONERY new product for electric water heaters that will bring your elect consumption down by 50%. after listening to this man for some time, i asked him if his trying to tell me that there's no relationship between ohms, volts and amps. He could not tell me the difference between inductive and resistive load. I however offered my company to be an outlet for his "wonder" product on condition that a unit be sent to us for testing and examination over a period in our lab, needless to say i never heard from him again. I'm unable to read the description on the pic above and agree that under volt will not let the motor start and burn out, but disagree with the statement that under volt will cause an increase in current, see Ohm's Law

I've used cream mixed with meths 50/50 on copper turning with exilent results... a tip from the late Arthur Presscot.

Thread: What Did You Do Today (2017)
17/04/2017 16:48:56

Put about a 1 inch thick bronze floor into my furnace today. Weighed out 15 kg material to do some castings for a loco, put it into the new preheated crucible, turn the furnace on in the meantime getting the molds ready and had breakfast. 30 min later things looked just fine, waited 30 min more and getting ready for the pour and to my dismay the crucible was empty bottom cracked right off, hence the new bronze floor. Will check in the morning what i can do to save my furnace S..t !

Thread: Bandsaw woes

Check if the blade guide or roller hasn't come loose and/or pinching the blade when it comes to rest on the stock being cut. Bad alignment can also cause nasty things
