I picked up this metal bandsaw off Boban today neat litle thing ideal for my use. I'll post better photo's late

It's a Toolex brand needs a bit of TLC, new BS Blade although the one with it works and some adjustment.

Does anyone have a user manual parts book??? I checked for ID plates can't locate any.

As to purchasing BS blades to use whats best TPI for use on mild steel & Alloy

Bonus was the little bandsaw table that came with it which turns it into an upright bandsaw :U

Ray, I've had one of those for years and they are very useful.

I wouldn't call the little table a bonus (next to useless comes to mind:o).

If you want to make some useful mods to this saw, have a look here (http://www.mini-lathe.com/Bandsaw/Bandsaw.htm).

PS The latest issue of Model Engineering Workshop has a neat mobile stand for it as well (#140 - July 2008 - page 42)

Similar, but not the same Ray, the other site has better details and different mods.

Just type mini-lathe.com in Google and when you get to that site click on Bandsaw.

What browser are you using, all 3 links work for me in Firefox and IE.

Looks like a beauty. I have always thought about getting a bandsaw like this one day. Hafco have a good selection and I think it will be more handy than one thinks.

Good pick up Ray .
Still waiting delivery of the motor for my power hacksaw ,thought it would have been here by now.
Been along while since I used a metal bandsaw.I reckon 12-16 TPI would be ok for the bandsaw blade .

Thanks all and thanks Fred for he files sorry still now photo's :doh: mate has scorced a manual for it get that Wednesday

Got to play around a little today a few adjustments and bit more clean up cuts well ok so it was a 19mm bar some run out.

BS blade is running off the bottom wheel if used in the vertical position have changed roller guides settings etc wheel camber

Is it possible the blade has become distorted through use, over tightening etc

The TPI size is more related to stock diameter and section shape .
For small diameter rods and square bars use a finer toothed blade.
The rule of thumb is use a blade that keeps at least 4 teeth in the cut at all times .
For solid stock as the diameter gets larger or cross section wider the tooth spacing can get bigger.
Standard high carbon steel blades will cut most metals like Al alloys and mild steel up to most metals that you can machine with HSS cutters , will handle D2 tool steels easy .
However stainless and hard alloyed tool steels need a bi-metal blade to preform well and you can get special tooth combinatios which have a fine section followed by a coarse section of teeth. These are available from saw doctors made to fit your band length and width.
With any blade in a horizontal saw you still have to make sure the job is not so thin that a tooth will drop each side of the job and jamb usually stripping some teeth and busting the blade.
As the metal gets softer and bigger in diameter the teeth need to be spaced further apart or a fine tooth blade will get clogged with swarf and suffer extra wear and very slow cutting. Heat may also become a problem leading to blade failure.
For hollow sections of thin steel a drop saw is a better choice as the bandsaw blade will need to be fine toothed to survive.
For long blade life it is very important to adjust the unit to get a good square cut and adjust the support rollers to properly guide and support the blade. On a Chinese machine this may take some re -engineering or adding of washers and spacers. The straighter the blade runs the longer it will last.
This site has some good links to bandsaw info wood and metal.

I followed Freds link and it works in Internet Exp.
However what I did see illustrates exactly what I was talking about before.
The photos of the melt down are a good example of what not to do with a metal band saw.
1/ Blade is too fine for soft Al leading to swarf clogging and overheating .
2/ The cutting deck has been built in like a wood docking saw so that swarf and heat can not escape easily.
3/ Whole situation leading to heavy strain on the motor.
4/ Also I think the thicker plywood inside pully cover has reduced the flow of air into or out of the motor.
Do not build in around the bandsaw vice it is open on the offcut end for a good reason.
If you are concerned about stock dropping and getting dents then be there to hold it as it drops. Or make up an open ventilated section that will allow air to circulate and swarf to drop through.
The main issue however is the blade TPI is too fine and possibly blunt.
This size piece of Al ( As long as it is not Titanium ) should have been a simple two or three minuet cut with the correct blade TPI and no clogging of the swarf .
You can see the built up swarf at the back of the cut and in the blade teeth , increasing friction , trapping heat and causing a major overload.
Motor could have been a poor quality Chinese motor also not helping the situation.

Bit wary of putting this link up Ray, you seem to have all sorts of problems getting to links, but here goes.

Was looking around a CNC site (http://www.cnccookbook.com/CCCookbook.htm) and found a whole heap of links to metal working stuff (http://www.cnccookbook.com/CCResources.htm), including this link to, wait for it, a 4x6 Bandsaw Group (http://groups.yahoo.com/group/4x6bandsaw/)!

I don't know where this guy gets time to go to work!:oo:
