I'll be bringing boring machines to the TFG Conference in VA, in November for sale. You could see and or try/buy one then.

Jim Rogers

Jim - the conference is about 25 miles of our house in Manassas and I'm planning on being there.  Hope to see you again.

Thanks, Bruce. I hope to see you again as well.

“what do you guys do with your mortisers to have to buy 30 of them?”

I suppose We cut a lot of frames, is the simple answer.  We frame 99.9% in green Oak and build traditionally jointed houses, some Post and Beam, some UK Barn Style, and quite a few half timbered / Black and White traditional English Manor house or cottage frames.
Last week we out 24,912 board feet of Green Oak though the shop, 2076 Cubic feet (our preferred measure) or roughly 190 cubic meters – Have a look at our website, www.oakwrights.co.uk.

“Oakwright what model is it that you are selling?”

Have a look at this rather sorry looking example on German ebay

3 phase – very heavy very robust

I also have the spec and handbook (thanks Denny) which I will try to attach


“in electrical class we learned. that is backwards....  110... is considered the most dangerous”

I don’t have the knowledge to answer that really, our 110 Volts are made up of 55 V & 55 V as a result of the secondary of the isolating transformer being center tapped to Earth / Ground.  I suppose the thinking is that when you get exposed to a live cable the shock is going to be 55V.  Its very universal here in the UK, broadly speaking all pro tools are 110V and all Home-owner DIY are 240V.

I, like many others, am a fan of the old boring machines.  No cords, easily portable, no flying saw dust to get in your eyes.  Nice wood chips, in tune with the wood, and only 30 percent slower than electric.  With a sharp boring bit, it's not bad at all and actually preferable to many.  Something to consider.  I originally bought a Makita, but I like the boring machine more now.

I like the idea of hand cranked boring machines.  Do you have a source for quality 1-1/2" and 2" auger bits that will work with these machines?

Right here on the forestry forum in the for sale section is this list:

check it out, I'd be happy to help you...

Thank you all for your replies, I learned a lot. Jim what is a TFG conference about? I am off to the old world, I guess we will see if I find some tools over there, now that I know most of them will work here. Oakwright you are doing some amazing work, you are a lucky guy.

[Brad_bb]

Jim sells good stuff.  I've never been disappointed.

[dukndog]

I second that Brad_bb!!!

[Jim_Rogers]

Thanks for your kind comments about our tools.

Hummm I would want to take any comment from such an electrical teacher with a grain of salt....240 V in North America is still 120 V to ground with each 120V wire out of phase with the other. So if you grabbed 1 of the hot 240V wires with your bare hand and bare feet it would only be 120V through your body. Now if you grabbed each phase of the 240V one in each hand well then you really would have 240V in your  body but most people get shocked through the ground connection. Plus it is really current that kills not voltage and the better ground rod you are...well 50V could kill you.

BTW interesting comments on the mortisers....as I always thought the makita was inferior and would like to do a side by side comparison! For now I will stick to my 2" Milwaukee bit in a drill and my boring machine when the drill is just too noisy

not true... 110  is 110, it dosnt split...   it alternates back and forth ON both leads. here in us...at 60 hz    the center tapped to ground...is neutral.

krusty...   the comment came from a licenced electrician.  cant remember what his name was..    yes..your right about the 2 phases of 240..  2 leads of 120.       i cant remember how the instance occurs...  that you wind up getting full voltage through you...     but i do know that current code is now 4 wire 240   vrs old 3 wire 240.  new stoves and dryers comming that way now.   basically 2 ground sources now.

I will dig through my elect stuff.   at a threshold of a certain voltage...  current or amps as we know it.. nolonger matters.
certain voltage...with low amp  will kill you dead.    i think it was 480..

do know... 240... way better/ in the aspect that it uses less amps,  less watts...  (which our meters nearly spin off the wall) cheaper to run, and will cold start a 2 stage air compressor at 30 below... wheras   110 wouldnt even start on the single stage.. so that got rewired for 220.
