Hi how wide of a cut do you make at a time with a 8-30 lucas;hard vs soft wood, always afraid the blade will lose tension if I take full 8'' at once; thanks

Hi Clairmont,

Full 8" with blade vertical hard or soft species

I have made 6" cuts with the blade horizontal in walnut just to see how it would do, it was fine.
Typically on an 8" cut horizontal  I'll split the cut and make two 4" passes.
I also place wedges when I'm making the second 4" cut, it keeps the
sawn board from potentially pinching the blade.

½ the width and all the depth in most species... You'll find it quicker to saw taking two  4" passes horizontally then labour ialong in a single 8" wide cut.

1/3 the width and ½ the vertical in Northern Red Ironbark, Jitta, Ironwood, Atherton Ironwood, and Clarksons Bloodwood.... But I doubt you'll run across that little lot too often.
The quickest way to make a million dollars with a sawmill is to start with two million.

You can probably nurse the mill through an 8" cut, but it's more practical to race though 2 x 4" cuts in less time. Easier than dealing with the horizontal bouncing etc.

The ironwood / bloodwood that LL is talking about is about an order of magnitude harder than Live Oak or anything that you will meet in the US. It's stuff that throws sparks off chain saws when it's dry. They have trees called Ironbark because when the early settlers hit them with an axe, it bounced .  :D

I have a Lucas 7-23 gas mill, and have had a blast with Doug Fir, Redwood, and white oak over the past year.  Timbers, siding, slabs, etc.  Picking up several stout logs of Eucalyptus Sideroxylon (aka Red Ironbark) on Friday.  In no rush to break circular blades and slabbing chains with it, but looking forward to seeing how it looks in slab and timber form.  A bit surprised to see it here in NorCal, based on what I read on the internet (Australia primarily).

Lucas 7-23 swing arm mill, DIY solar kilns (5k BF), Skidsteer T76 w/ log grapple, F350 Powerstroke CCSB 4x4, Big Tex 14LP and Diamond C LPX20 trailers, Stihl saws, Minimax CU300, various Powermatic, Laguna, Oneida, DeWalt, etc.  Focused on Doug Fir, Redwood, white and red oak, Claro walnut.
