G'morning all,
I'm setting up a small cutting area in my apartment and will be making test items using a dremel bandsaw, it is not a volume production line lol. Being that it's in an apartment I want to make it as particle free as possible also, taking into consideration that steel particles can be hot. the items I will be cutting is hypodermic thin wall tube and some .375.od with a .02 wall
What I am thinking of doing is using a small vacuum that attaches to the bottom of the saw as well as splitting the hose into two, part A sucks from the bottom and part B is then split into two and goes either side of the lockdown. (It ain't no Picasso) Also I would make the hoses 4' long to allow some cooling to the cut particles.
My question is, being that I am basically running 3 hoses out of this lil ol vacuum.
a) am I going to overheat the vacuum.
b) will I be able to cool the particles down enough so as not to cause a fire in the vacuum.
Bare with me as this is my first attempt at this type of project and, if you think it's crazy tell me
Thanks

pic doesn't look like a bandsaw - looks like a reciprocating scroll saw. Would not be my 1st, 2nd, or 3rd choice for cutting thin wall steel tube. when sawing tubing, typically one uses a blade with fine enough pitch to have 3 teeth engaged in the cut at any given time = for a 0.020" wall, that's a blade with ~ .006" pitch (distance between each tooth).
I'd suggest using Dremel with an abrasive disc like a chop saw. We cut 3/4 OD x .0.030" wall mild steel tube with a regular tubing cutter.
To answer your question concerning the vac and chip temps - normally, swarf from scroll sawing is not hot enough to melt/burn anything - simply use your vac's narrow tip/hose to catch them. You could fashion guards from cardboard if needed. Seriously, I'd be very careful trying to saw that very thin wall tube in a scroll saw.

Thank you Tom, I should'a asked the question before buying this lil ol scroll saw, Guess I'll be buying the chop saw (shoot). Being that I am doing this in my apartment, I wanna try and catch all particles during the cutting process and the scroll only has an under saw vacuum, I figured that if I attach two smaller hoses to the main hose, and then bring them up to a position slightly above and either side of the cutting blade, they would catch whatever flies that out of the top.
I also use a tube cutter, I cut to twice the length that I want then, cut in half with the hand tube cutter. My reason is that I am making some tools and the hand tube cutter smooths off the open end, as well as inverts and changes my diameter a little.
Thanks for the heads up mate

I ended up getting a Proton Chop and Miter Saw KGS 80, works great
Thanks
