From experience, it's still a problem. With a TS mounted drill, it'll still try to self feed, either jamming the machine or popping the chuck out of the TS taper. With a carriage mounted drill, it'll

G'day Jim At first I took note of your caution about connections in the motor circuit***. However reading the KBE data showed that they allowed for a fuse in the armature circuit; that would open

Yeah, the KB's are good - Homier/Speedway USED to use them, but they've gone to the SIEG units, now. Nothing really wrong with the SIEG units that abit of ":fluffing up" wouldn't fix. <G>

His real bull is SCR as I remember, John.

oh, and I'd love to see the pictures, even if you just want to e-mail them over to me ( use radid@... - that's my own domain, so lot's more storage there - this mailbox is a bit on the

This technique works better on the SCR units than it does on the PWM units, as it's often diffucult to get around the fact that's pulse DC on PWM. However, using a clamp-on style meter can net you

G'day John et al. The meter is a moving coil type. The inductance of the motor armature should smooth the current enough for a reasonable accuracy. BTW, meters used on much larger drives were moving

G'day all. After talking about it for a while I have finally hooked an ammeter into the motor circuit. The meter is a small 0-5 amp movement which I mounted in an ABS box. This box hooks over the back

G'day Andy. Before writing back on the Sodium Metabisulphate I did a quick Google check as I also recalled it was metabisulsphite. It seems they are interchangeable as sterilising agents. The

Nope, ok here. Stu G

No, I just downloaded 2 DOC files and watched a MOV of the Adj. Backplate. :) However, are we back to duplicate posts again? Some look very familiar. 8-|

Hello Folks, To be pedantic, I think that the sterilising stuff is sodium metabisulphite (Na2 S2 O5), rather than metabisulphate, but I don't suppose that would make any practical difference. I might

G'day Ellis Drilling from the tail stock is OK but the drill or chuck is held by a taper. If the drill self feeds it breaker its grip with the taper and slips. An exercise in futility. You have to
