Re: Boom Arm progress
Maybe there¡¯s a misunderstanding of where the bearing is. Randy, did you expect the shaft to be fixed on the arm, ie, the shaft is bound to the bronze ¡°bushings¡± (which are actually bearings)? And thus the shaft is rotating? ?? Since Joel¡¯s photo shows bronze bearings, I assumed the shaft was fixed.? One thing is certain ¡ª there is no point in both the arm and the mount having bearings.?

Note this is functionally the same as what Joel showed in the pic below.? My main point is that it can just as easily be made of scrap wood, ie you certainly don't need to add $100 of flanged bearings and brackets just to hold a shaft. |

¿ªÔÆÌåÓýSam, if it is a NO relay and is testing short you may have found at least one bad part. however, to be sure that the relay is shorted, as opposed to another component in parallel, you will need to remove it from the PCB and confirm. imran?

? [Edited Message Follows] So - not sure how reliable this test is as it's done on an installed component but, I've found that one of the relays appears to be closed, whereas the other is open. I'm relatively sure the diagram on these relays indicates "normally open" so.Should I remove the relay that appears to be closed and is potentially faulty to test on its own, or would I be safe in assuming that is the problem? And thanks for that Davy - learning loads here hah! Will move onto thyristors after the above methinks.. |

Re: Zero Clearance Inserts for Hammer K-3
¿ªÔÆÌåÓýHello Bob?I couldn¡¯t agree more! I¡¯m surprised that sliding table saw manufacturers don¡¯t offer better throat plates. ?I¡¯ve worked on many different brand sliders...the throat plates are always lacking...they simply allow too much space around the blade. ??
I absolutely love mine now...the tiniest of pieces fall harmlessly away or I can fling em out of the way with a small offcut to prevent them from going up the dust hose. ?
Your inserts still ship this afternoon with some others ?
?Much thanks,

A RAS is a very versatile tool. It does many things poorly, and dangerously. It can do one thing well, but other smaller machines do it just as well without the same safety concerns. I'd fogetaboutit

Re: Oliver 192 bandsaw
Mark,?
I acquired a 192 last year in real rough shape. I've been working on getting it up and running lately. My hope is it is the general, cut anything?saw. It can free up our Feder 540 to be left set up for resawing, and our tiny Rikon with an 1/8" blade for cutting the tight curves. Mine is very early by comparison. Just had some new guide blocks machined to hold the ceramic blocks I got. I'm hoping its a great little saw. Used to look like this Jason Holtz J.
