Thread: How to go broke and some hot boring action.

One of these days I must work up a list of my TS drill bits to see what sizes I'm missing & what sizes I have multiples, then see if anyone wants to swap some. Currently I think 1 1/2" is the biggest I have, which both the Monarch and the Arboga have no problems poking into a pilot hole. On Ewan's comment WRT a Hercus drill, a friend of mine has one he wants to part with. It has power feed etc, stands about 2.1m high, not sure if it's 3MT or 4MT. Priced well but he isn't shipping it anywhere. It's in southern Tasmania. Anyone interested can PM me. There's a late 1800's English make lathe too but frankly I wouldn't have it for free - big, slow, heavy, accuracy doubtful. PDW

Shame it's down there. I curse my Chinese POS drill press every time I use it, without fail!

I think I'll always regret the decision to sell the Flott, and knew I would at the time, but that's life. It was without any doubt the sweetest machine I've ever seen run, and it was only a drill press. Go figure.

Impressive... At what diameter do you swap over to boring bars?

For me, 1.5" because that's when I run out of drill bits. If I had bigger bits, I'd use them in the Monarch and it'd handle them without any dramas. It has a 4MT tailstock with locking tang slot (and let's NOT start that debate again). I've recently been making adaptor flanges with minimum 2" bores going up to 3.5" and it's a PITA boring them out instead of drilling them with one or two final boring passes to clean up to size/straight. However I still want a Kearns S type HBM..... PDW

You could get lucky - might be a trip to Qld to pick up a surface plate in the near future.... PDW

yea it is usually at the biggest drill bit that I have that is undersize the bore, or a couple of mm..

I have added another pic here of milling with the borer https://www.woodworkforums.com/showth...40#post1807440

Just to keep Pete happy...

Had to make up these pins... They have a 90mm long 8.5mm hole in them, then counterbored and tapped 1/8BSP for a grease nipple..

Was so easy on the borer.... Just spin the table 90 degrees so the vice end is showing, then centre the drill and go for your life...

Was so easy with everything within easy reach...

Yeah. I used to use the TAFE Kearns HBM for stuff like that, back in the day. Makes a lot of jobs a piece of cake. Recent boring job pic attached. I had enough Y travel but only just - it is only a small mill after all. Would have been *much* easier on a HBM. PDW

Pffft. No prize I'm afraid. Pete can do exactly the same thing as that on his horizontal mill

Neeeext!

Yeah but you don't have power feed on Y or Z . PDW

Hi RC,

Not sure exactly what I'm looking at, it looks like you are about to power tap, but that would mean either letting the head or carriage float free so the tap pulls in, or are you somehow adjusting the Z axis power feed rate to match the thread?

I don't see a quill either..

As Pauline says... please explain

Ray

Ray the traveling spindle just floats there, it has 27 inches of travel in two stages..... it is as free as say a quill on a drill press without the return spring... You can zip it in and out very quickly.. Great for deep holes and cleaning out the drill..

The machine has clutch forward/reverse on the one lever... So you can clutch it in very easily for tapping.. Plus the 24" square rotary table is marked in degrees so you can spin it around accurately... In fact originally the machine would have had a dial indicator for very precise rotary table placement, but it is long gone, no doubt smashed by someone, but the pin holes are there...

That all makes sense, the forward reverse clutch would make it dead easy. Engage forward, watch the depth and reverse out.

I need a bigger shed...

True true. [sigh] I'll make whirring noises next time I use it and pretend instead. I am a bit of a pretender, or so I'm told

Richard knows how much I like horizontal borers and is just rubbing it in. I just pretend I like the guy so he'll post more Youtube video of it in action!
