what type of sawmill

Hi all,

I am in the planning process of building a mill to process root balls. Taking into consideration of the debris in the root system, dulling or destroying teeth, the cost of cutting bands or chains, etc...what is the best type of mill? Band or chainsaw. Please state the reasons for your opinions.

Thanks,
Michael

It would help to have a little more information. What size root balls? Just a few, or will this be the foundation for a business?

I have milled walnut root balls with both chain saw and band saw mills and, in general, find the band saw mill to be much better IF it has a clamping system that can adapt (my Norwood mill is very good in that regard). Whatever you use, you WILL destroy chains or blades. Band saw mill blades are quick and easy to change and are less expensive than chain saw chains. Band saws cut much faster and take thinner kerf. Also, don't overlook the possibility of other specialty cutting, such as slabs. Band saw mills are much faster for this. They are also cheaper to run, and are designed for milling, as opposed to chain saws, which are not meant to run under full load for extended periods of time. Hope this helps.

Dave,
Thanks for your input. The business foundation is to process root balls, large slabs and other specialty cuts. I am in the planning process of building a mill large enough to cut about 60".

Are YOU actually building or you having it built???? I would like to see pics. Hud-son has a new wide unit. I've dreamed of a wider mill also...debating the cost/income ratio for my area.

If you are routinely cutting slabs that size, you may want to consider a swing blade mill (Peterson or Lucas) with a slabbing attachment. I have several friends that run them with good results. There are a number of Youtube videos showing them in operation. Designing and building your own band mill may set your business back, due to the time invested.

I (or my team - a fab guy, a mechanical engineer/draftsman and me, the crazy guy wanting a huge mill) will be building it. The plan was a 60" but I am now rethinking since I have a heavily burled maple log laying here that is 9' long and is 7' across. This is what got me thinking of a chain mill. I can buy a 102" bar. My biggest problem with a band mill that large is the width of blade needed for tension, strength and ability to cut straight and not dive into the log at that span. The cost of that blade then risk rock and debris in the root balls???? Has me questioning.

Your logs keep getting bigger! Visit the Hearne Hardwoods web site http://www.hearnehardwoods.com/ if you haven't already. Better yet, you & your team should go pay them a visit. Nice folks, doing some amazing work with a band mill.

I like Dave's idea of visit the Hearne Hardwoods, and maybe even take that log you mentioned to them to custom it saw for you. this way, you get to start working on marketing. You might find that building the mill is the easy part.

Here is a link to another mill that can saw large slabs that built their own mill.

Video of my diy chain mill with 650 Mag. Will handle a 62" dia log Was pleased with speed and accuracy. Now have my diy swing blade mill near completion. It will make a 10.5" cut with 32 hp gas engine. It will be controlled from end of track via hydraulic motor to power saw carriage forward & back on same 62" track width. . The swinging of blade function will be done with wireless remote controlled 12vdc boat trim/tilt pump and one outdrive ram.
Also started a diy dedicated slabber, fabricated needed parts and purchased other parts for another chain mill using 18 hp B&S riding mower engine powering a jackshaft to get proper chain speed. Will use it as a dedicated slabber to run on same track as the other mills.
Am retired, 30 plus years owed a tree service, am a sawdust addict! Like to build projects.

    WOODWEB's forums are a highly regarded resource for professional woodworkers. Messages and responses that are crafted in a professional and civil manner strengthen this resource. Messages that do not reflect a professional tone reduce the value of our forums.

    Messages are inappropriate when their content: is deemed libelous in nature or is based on rumor, fails to meet basic standards of decorum, contains blatant advertising or inappropriate emphasis on self promotion (return to top).

    Libel:   Posts which defame an individual or organization, or employ a tone which can be viewed as malicious in nature. Words, pictures, or cartoons which expose a person or organization to public hatred, shame, disgrace, or ridicule, or induce an ill opinion of a person or organization, are libelous.

    Improper Decorum:   Posts which are profane, inciting, disrespectful or uncivil in tone, or maliciously worded. This also includes the venting of unsubstantiated opinions. Such messages do little to illuminate a given topic, and often have the opposite effect. Constructive criticism is acceptable (return to top).

    Advertising:   The purpose of WOODWEB Forums is to provide answers, not an advertising venue. Companies participating in a Forum discussion should provide specific answers to posted questions. WOODWEB suggests that businesses include an appropriately crafted signature in order to identify their company. A well meaning post that seems to be on-topic but contains a product reference may do your business more harm than good in the Forum environment. Forum users may perceive your references to specific products as unsolicited advertising (spam) and consciously avoid your web site or services. A well-crafted signature is an appropriate way to advertise your services that will not offend potential customers. Signatures should be limited to 4-6 lines, and may contain information that identifies the type of business you're in, your URL and email address (return to top).

    Repeated Forum Abuse: Forum participants who repeatedly fail to follow WOODWEB's Forum Guidelines may encounter difficulty when attempting to post messages.

    There are often situations when the original message asks for opinions: "What is the best widget for my type of shop?". To a certain extent, the person posting the message is responsible for including specific questions within the message. An open ended question (like the one above) invites responses that may read as sales pitches. WOODWEB suggests that companies responding to such a question provide detailed and substantive replies rather than responses that read as a one-sided product promotion. It has been WOODWEB's experience that substantive responses are held in higher regard by our readers (return to top).

    The staff of WOODWEB assume no responsibility for the accuracy, content, or outcome of any posting transmitted at WOODWEB's Message Boards. Participants should undertake the use of machinery, materials and methods discussed at WOODWEB's Message Boards after considerate evaluation, and at their own risk.
