Metal Bandsaw

[wheelinround]

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

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).

If you want to make some useful mods to this saw, have a look here.

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.

nope not in IE or Firefox may have security settings to high I am using a laptop will try later on PC

Thanks again Fred

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 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

Link is working for me.. using Firefox here.

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.

Thanks Retro

I was lucky enough to be given a copy of the manual today so hopefully I can sort out my trouble even they be it a small one
