    Default Mk3 upgrade clarification - saw chassis

    I've got a second hand Mk3.

    Now, what exactly does the saw chassis upgrade get me?
    Does it allow me to go for the height winder?

    How well does the stabiliser work - I got a 235mm Hitachi with the bench. Is it worth it?

    Chassis upgrade lets you put the height winder on. I retro'd mine about 6 months ago, and am delighted with the result. The improvement in usability with the addition of the height winder, is magic.

    I would strongly recommend the saw stabiliser bracket, if the weight of your saw motor causes the saw to sag. ie pulls the blade out of perpendicular. Since adding the bracket, I can now reliably get my blade perpendicular. Does make it a bit awkward to angle the blade, but the benefit out ways any inconvenience.

    Is the stabilising bracket in addition to the saw chassis upgrade, or require it? Would it work with the original chassis?

    There is lots of stuff in here but noone seems to get completely specific with the usability side of thing. To further confusion, I had the impression that the Triton saw had special cams for perfect alignment - now I read that the Mk3 does not work so well with it - why is this?(!)

    To completely upgrade your old chassis to the latest model fitted to the Bunnings type workcentres (fitted with a height winder) you need...

    1x chassis upgrade kit
    and
    1x height winder kit

    Option for improved accuracy is to ALSO add a saw stabiliser bracket to help with the problems of saw slump (where the weight of the motor when hanging upside down from the workcentre chassis - causes the motor to pull the saw blade over and off plumb)

    If your Hitachi saw is a C9 - they are a good unit, and from my expiriences did not suffer as badly from saw slump as say a similar sized Makita.

    The difference between and old chassis and new chassis is the old chassis was a grey, cast alloy, 2 piece angle section, that only supported the saw at the very front and rear of the saw base plate. The new chassis is a Grey (or sometimes orange) powdercoated, 2 piece, pressed solid steel plate that supports the saw more central and evenly, and of course allows for the fittment of the height winder.

    The alignment cams will ONLY work with the Triton 9 1/4" Saw - and only on the new style chassis.

    Sorry, but they DON'T.

    I upgraded the saw chassis to the new style to allow me the use of a height winder, and that is the only reason to upgrade the chassis as you can already fit a saw stabiliser bracket to the old one, and then later I got the Triton 9 1/4 saw.

    Whilst the alignment cams will fit the saw chassis the are in the wrong place for use with the MK3 table top for the fence ruler scales to be accurate.

    So you will still have to use the old fittings.

    Thank you both for your answers. This is precisely the detail I was looking for!

    cheers

    Sturdee,

    Many apologies, I stand corrected....the first line does indeed say Mk3

    I thought all of those were in museums by now - or happily resting under RTA300's after the owners had traded in the tabletops.



    havenoideaatall,

    Ditch the alignment cams idea...I was never a huge fan of them anyway.
    Im glad we could answer you questions.


    Dohboy.

    Still think the alignment cams should have been ditched in favour of a threaded system (horizontal) allowing accurate, precise alignment.

    The last post was 14 years ago, most of us, including me, have moved on from the Triton setups so I can't help you anymore. The others in the thread have moved on from the forum.

    Might be better to start a new thread rather then resurrect a dead one.

    Peter.
