Re: The making of a 14inch homemade bandsaw





The tensioner. I hope this works.

You guys know where can I score carbide blades? CArbon steel are a-plenty but I read that they are only good for curve cuts on thin stocks (the bodies of electric guitars e.g.) as they have too many teeth in the stock at any given time (5 tpi = 20 teeth gnawing away on a 4" stock. Recommended is 6 to 12 teeth depending on thickness) A 2- or 3-toothed hook teeth carbide blade is the best for resawing wood as wide as the bandsaw's depth of cut can take (10" to 12" on mine). I still have to try resawing with a carbon steel blade though.

TIA.

Re: The making of a 14inch homemade bandsaw

Fantastic drawings bro, galing!

You might want to consider rearranging the blade tension mechanism so the screw is from the top and also in tension. This will avoid having to have the two necessarily accurate slides you have now have. The drawback however is that it makes adjusting the tension a bit inconvenient but you don't do that often.

Some bandsaws have a quick tension release - just a lever that lowers the fixed nut of the tensioner screw. You shouldn't leave the blade in tension when not in use.

Timber might know where to get the blades. To be honest, I did not even know there are carbide tipped bandsaw blades. I'll try to ask my local industrial supply when I get the chance.

Re: The making of a 14inch homemade bandsaw

Thanks bro. I owe using SketchUp to you 🙂
I was considering putting the adjuster on top but I guess it would necessitate having a sturdy enough column of steel to attach it to. In contrast the frame in my design will take all the load/stress of the adjuster AND the column. And the point where all the loads will be concentrated are not far from each other, too. I just hope the steel rods won't buckle nga. But thanks for the insight bro.

@ bandsaw blades:
Calling bro timber:)

Here are some projects that's gone unfinished for months now. One was sold to a friend. I simply have no time.

Re: The making of a 14inch homemade bandsaw

It's halfway finished! not really. Still needs a lot of work.

Mang Nestor - welder/machinist

So rough. Will probably look better after several coats of paint.

The pillowblock won't move, saving me from constant tuning/aligning

The plate steel is from the base of a stand fan, 3/16" thick

Re: The making of a 14inch homemade bandsaw



The flimsy iron bars are used to temporary align the table. It's going to be replaced by angle bars. Will be welded permanently. I'm thinking of using jigs if I want angled cuts.


I found these planer blades in an old harware store. Will use the Tramontina in my 17" planer. I remember reading about the Tramontina brand somewhere in this forum.

Re: The making of a 14inch homemade bandsaw

To be honest, I've never used a big bandsaw however I've heard a runaway broken blade is something to really watch out for. I've seen this on my little bandsaw and even that is kind of scary. Be careful Bro. Safety first.

Re: The making of a 14inch homemade bandsaw

Thanks bro lncc. SAfety first. I'll encase both wheels with 1/4' ply. Even the drive pulleys will have some kind of a guard. The wheels are in perfect alignment I would say. The tensioner works. Adjusting/centering the blade is not that hard. and it will be easier when the wheels will have some kind of tires. 3/4" conveyor belt will be used.

@angelo
Di pa ako handa gumawa ngayon brod. Maybe next year pag nagawa/nabili ko na mga ibang gamit sa paggawa.. I'll keep you posted. Thanks.

Re: The making of a 14inch homemade bandsaw

Hi guys! Sorry for bumping up an old thread. Perhaps somebody will benefit from my experience in building this bandsaw;)

Well, he it is now(well it looks the same a month ago actually)


I made a 1/2" plywood sheat to house the exposed blade and also ply for the wheel cover


I'm using a clamp to hold the steel rod(forgot the proper term) that holds the blade guide.

Re: The making of a 14inch homemade bandsaw

Here is the blade guide. I found those thick-walled tubes (nothing more than 1' shaftings that have 5/8" or 3/4" holes drilled lengthwise through 'em) in a farm supplies shop.


I tried making some part of the guide in ply but it proved to be no the right material

Tried making it from narra (the only handy scrap i had lying around..)

Voila! Perfect!

Re: The making of a 14inch homemade bandsaw

Here are some additional pictures;



you can see how the 2 blocks of kamagong straddle the blade. This is much cheaper than having two bearings to keep the blade from drifting left /right.

I can adjust the bearing to just a hairbreadth away from touching the back of the blade; ditto with the kamagong blocks.

I still have to test the bandsaw as my motor(1.5hp 1740rpm) is still in our house back in Kalinga. The blade centers well on the pulleybelt-cushioned wheel. i've also wrapped/glued a 1/2" strip of plain old tirador rubber on the wheel to help center the blade.

There. I'll post again when there's a lull in my 9-5 job:) Thanks for looking!
