Re: DIY Bandsaw
Final cutting height is around 10.5" inches after table and blade guides are installed, throat size is also 10.5 inches, not bad for 14" wheel band saw I guess. My sketchup plan for the table is 18" x 20" and it will stay "flat" so no trunnions will be installed underneath coz i don't forsee the need for angled cuts, if there should be then it's easy to make a sled/jig for it.

Will it be easy for you to upload Sketchup file so i can print a 1:1 scale to?
i Bought an 2560mm blade, will it fit on the new scale?
Re: DIY Bandsaw
I think it would be better if I email it to you so you can play around with it and take all the measurements, I saw your sketchup plan of your intended revision of my design. Send me a private message stating your email.

Re: DIY Bandsaw
I continued working last night on the shaft block.
here I inserted the nut on top of the block, this will be the same on the other side.
I added glue to bond the metal and the wood.
.
I then fastened a washer to secure the nut.
here is the video showing how the tensioner assembly works.

after taking the video I dyed the whole assembly to enhance the wood grain, it will not be included during painting of the frame.
this reminds of medieval machineries.
Re: DIY Bandsaw
Bro Armand, the top block looks like a weak link to me.
It might fail along the red line
Or maybe my eyes are just fooling me.
Re: DIY Bandsaw
good catch joey, actually wrong angle ang nangyari and then the flat bar that i got was way too wide from the original plan.
I just proceeded..trusting the guijo wood and the dowels in the middle will hold the tension, i know guijo is tough. Plan B is on the drawing board just in case.
Re: DIY Bandsaw
I think the main force will be absorbed by the side steel rails rather the to wood.
I REALLY wanna see the result of this project....
HARRY UP Armand!! 😀
Re: DIY Bandsaw
Joey's concern is really valid and i have a couple of ideas to address it.
1. Compression springs above the shaft block will absorbed the tension. I will rip my drill guide to get the springs. (compressions springs are order basis in most hardware stores, haven't tried auto supply shops).
2. Angle bar above the block in question will reduce chances of breaking (I hope).
Re: DIY Bandsaw
I don't think it will make any good my friend, if you push the blade the wheel will come up and the blade will get distorted as a result not cutting straight lines.
You need to keep the tension steady at all time, especially at resawing.
Sorry if i misunderstood something.

Compression springs from salvaged machineries are available at Tony's Junk shop near at the corner of J. Molina Ave. and E. Rodriguez Hiway in Concepcion Marikina. It's very near the stoplight. People in the area could easily guide you to that place. At least this could help you from taking them from your drill guide.:)

Thank you sir @willyfernando for the sources of compression springs, I got my flat bars and and shafts from them too. The shafts were threaded at the machine shop very near to Tony's. I was able to get my flat conveyor belt (korea) also from Sygal at P35 per foot. Your tips saved me a lot of footworks by avoiding Binondo. Balik ako sa Tony by wednesday for the springs.
Re: DIY Bandsaw
Sudden trip to Batangas left me only a few hours of works for my band saw. Managed to finish only the wheels.
.
here the two wheels were already cut. Two layers of HDF materials (not so sure) from doors of broken cabinets that i bought (only the doors) from a Japanese surplus store.
and here is the jig for cutting the wheels.
dryfitting time again..
and spun by hand only.
hope to have a dry run this coming wednesday if ARQ or Marios Merchandising are open this coming holiday for my bandsaw blade.
Re: DIY Bandsaw
Wow...seems very nice!!!
Very nice work mate!

Tony has another shop in Nangka, a bigger one. It's his salvage yard where all kinds of stuff will wet your imagination on everything DIY. By the way, have you considered incorporating a speed reducer for your motor like a worm gear reducer or frequency inverter? It makes a lot of difference in cutting and blade longevity.
