Meba Bandsaw Cutting Direction ?
micktoon:
Hi Andrew, I think John is right as my saw cuts away from the fixed jaw and came from Metal supermarket Gateshead , they cut lots of metal and had the saw maintained and repaired by professional company so I think they would have set it up correctly.
All I can say is I have wondered about the direction before but I am sure the arrows on my wheels confirmed the direction was as intended on my saw. The other thing is it cuts great and straight, so I also just thought if it's not broke don't fix it lol.
Cheers Mick

Thanks Mick. I had a close look at one of the pictures in your rebuild thread and deduced the same from the tooth shape :thumbup:

Well it seems to work :clap:
If you remember from my opening post this band saw was dragged back to life to cut up some Forklift Forks to donate material to make Vee Blocks for shaft straightening on my 60 ton press.
Impatience being my middle name I had at it this afternoon. The forks are 40 mm x 120 mm - I'd have preferred 50 x 120 but you work with what you have. The saw has two speeds selected by manually changing a Vee belt (dodgy Vee belt - spare on order !) and is running at 120 feet per minute at the moment with an 8 tpi M42 blade and oddles of coolant (must cure that drip!)
It took about ten minutes and gave a remarkably clean cut - no idea what the steel is but it will be something pretty tough to stand up to the abuse of being a forklift fork.
I'm certain now that the saw was originally designed to run the blade in the opposite direction - ie left to right - as otherwise it wouldn't need a swarf scraper on the 'entry' to the right hand wheel. But in the light of John S's comments, and Mick saying his one runs right to left that is the way I'll leave it.
The eagle eyed amongst you will have noticed I've fitted the extra nozzle to the left hand guide, but it's not plumbed in as I'm still awaiting the Tee junction.

This reversing the direction of cut is very interesting, My cheepo Clarke 6X4 band-saw has a tendency to derail, which despite my concerted efforts still plagues me! I've trued up the wheels, checked wheel alignment and made a hydraulic down feed, all to no avail! I'm going to see if I can reverse the motor!
Thanks John for pointing it out!
Regards, Matthew

It's interesting (at least to me!) that Mick's Startrite Melba cuts 'right to left' and I'm certain my (pure) Melba was intended to cut 'left to right' but has been modified. I strongly suspect that Micks is somewhat younger than mine, and maybe was made after the wisdom John S revealed became general knowledge.
It'll be interesting to see if Matthews modification to his Clarke makes a difference.
