Bandsaw problems.

I have the following bandsaw and I have terrible problems keeping the blade on.

Only way I can keep it on for a full cut is by turning the speed of drop down to a painfully slow speed.
It came out a university engineering teaching school so wouldn't have been too hard worked.

What am I doing wrong? I tension the blade up almost to the point I cant turn thr wheel anymore.

Donk know much about bandsaws and may be just camera angle but looking at the last picture with the guards off the blade doesn't look like it's running flat to the wheel on the left at the top. Is there a guide in there or are the bearings in that wheel OK?

Lack of lubrication will not be helping, also you need to match the blade to the material you are cutting, that looks like a blade for solid section, basically if you cut box section etc the teeth will not be supported by the teeth in front running on the material and will fall down and jam the band.

I had the same problem with a Clarke bandsaw and the answer from Google was to fit a good quality blade.
Google also told me what a good quality blade make was and sure enough the problem disappeared. I can't remember what the make was, sorry but it went from being almost unusable to never coming off.
 
i know its surpose to run in all places but i would move the right side arm closer to the middle of the machine as i think it not letting the blade twist back enough to go onto the drive wheel ,, as said before blade type and quauilty are important as is down force pressure ,,,, keep playing it will come rite they can be tempremental
 
Try this place for blades, it's where I get mine from. https://www.justbandsawblades.co.uk...1WM-S9MGsNypjR-E6C7I_RJYwuuuiWYAaAh5mEALw_wcB

As said the blade type is important, also the brand to a point. Make sure the width of the belt and the length are correct for your machine. When tight, the belt should ring like a tuning fork if you pluck it like a guitar string.

I'll take a look at mine this afternoon and see if I can think of anything else that stands out.

All the best

What's a good tpi for cutting the widest range of stuff? 2mm box up to 10mm RSJ's

Or is that really the job for 2 blades?

While we're on the bandsaw topic. I have a Spaldings bandsaw that has coolant like most of this type. A great saw, quite and precise cuts. However lately the coolant only works for a few seconds and then just seems to slow to nothing. When it's running have plenty of pressure but then drops away. Have plenty in tank and have checked everything I can. Anyone any ideas?

Will the blade stay tracked if you run it without cutting anything? also if your over tensioning the blade that can pull the wheels inwards and alter the tracking the band wheels should also have a certain amount of crown to them because the blade will want to ride at the highest point

Does the idler wheel bearing housing have adjustment bolts similar to the three marked with red dots, underneath the saw to adjust the wheel tracking? As mentioned above the two wheels need to be true.

Have you got the blade the right way round the powered wheel needs to pull the blade through the cut not push it if you get what I mean?
