hello all,
i have purchased an second hand drop saw (hitachti c8fb 8 1/2 inch) and i think it needs a new blade. the offcuts have scorch marks and cutting is generally slow. however, i was wondering how to get the damn blade off. the spindle lock works fine but i cant seem to free the bolt which fastenes the blade down. ? can any one shed any light on the matter? and also, are there any decent blades out there that you folk could reccomend? thanks again.

Check that you're not tightening up the saw instead of loosening it.
Without seeing it, I can't let you know for sure, but a lot of these have left hand threads eg: as the blade spins, it tightens up the thread, to undo the blade, you have to turn the bolt in the opposite direction to the rotation of the blade.

it was left hand thread. thanks alot. reccomend any drop saw blades?
Ballew Saw and Tool carries Freud and Systimatic saw blades. They both make blades for chop saws:
http://www.ballewtools.com You could probably call them if you don't want to weave through the on-line catalog. I'd highly recommend their printed catalog -- they carry a number of excellent lines of blades and bits. 1-800-388-7483

Hi Gazza,
If you're local, Irwin and Nicholson sell good ones through trade suppliers.
Make sure that you buy the blade from someone who understands your needs, a local saw doctor is my recommendation.
eg: Aluminium, tooth included angle greater than 90 degrees (is this pos or neg rake, I can never remember?)
Chipboard, multiple tooth, Triple chip (I actually use a steel cutting blade for chipboard, works beautifully)
Timber, teeth slightly hooked, many teeth for smooth cut, if you're cutting rebates/grooves, you need a triple chip blade, if you're docking to length, an ATB (alternate top bevel) should do the trick fine.
This is a really rough summary - find someone reputable who knows their stuff. If you can't find anybody local, Carbatec sell the CMT (Italian) blades that are also good, but pricey. 1800.683.583

gazza,
Eddie is probably correct, a left handed screw holds the blade on. You might be able to get some detail instructions on line ....they have a good reputation as a chop saw. For a blade, I'd go with a Freud..it will make a big difference..the tooth count, etc. depends on what your going to cut. Good luck, hope you enjoy
I have two of them. Exellent machines. Like was posted by others, left hand thread (turn clockwise to loosen) Freud blades, don't cut nails and you'll get years of use! Good Luck,
John
