It will be a 14 incher with a 12inch cutting depth. My goal is to make it with a budget of 10 to 12k only.
Actually I designed it and have it built by my friendly neighborhood welder and machinist:)
While scrounging for the frame materials (I envisioned junkshop angle or I-bars) I started making the wheels using a homemade circle cutting jig with my laminate trimmer
wheels are made from 3/4" plywood
Two 3/4" wheels were glued together
The two wheels with the materials to be used for the axle of both the upper and lower wheel, upper wheel bearings, the pillow blocks for the lower wheel and the block steel and steel rods for the tensioner assembly.
I was kinda worried about my wheel design. I thought the axle and bearing housing design will hold but the plywood wheels will be hard to align once mounted on the frame.
Re: The making of a 14inch homemade bandsaw
When I went to BAguio for a training, I found this in a hardware store near SLU
14 inch handtractor pulley. Perfect! They also have 18 inchers for really big bandsaws!
So instead of having a separate bearing housing for the upper wheel, the bearing will reside in a recess in the pulley's center (hub). Barely enough to fit a 6205 bearing in.
A short tale:
I was on field in the mountains for a number of days and guess what I found?
It's a craftman 8 1/2" plane! Got it for P300 from an old man who confessed he had no thing for metal planes. It was given to him by a brother in HAwaii.
I lapped the sole and now it's one of my treasured tools. In fact I used it in one of my other WIP: a 17" handplane!
Re: The making of a 14inch homemade bandsaw
Here it is. The handplane WIP, I mean. I hope posting WIPs in WIPs is allowed:)
Gluing the center laminations together

Squaring the resulting white-black-white lamination with no less than the craftsman plane. Very sharp for a 300 peso plane!

Thicknessing the kamagong board that will be the sole
Gluing the cheeks. Both 3/8" kamagong. Oh I almost forgot. I cut the center wood into two. The part where the blade will rest got a 50 degree cut (as seen from the side) and the other a 45 degree one.
The 3/8" sole glued

Re: The making of a 14inch homemade bandsaw
Meanwhile.. back to the bandsaw project..
I lost a lot of pictures when I formated my card thinking that I've saved what's in it. Careless!! Anyway here's what I managed to save.
From the steel block in the previous pictures, MAng Nestor, the machinist and welder extraordinaire (well, in the neighborhood, he is!) made this. The axle is from a tricycle's 3rd wheel, ready to accept 6205 bearings. The upper wheel will ride on two bearings for smoothness. If you notice, the steel block where the axle was welded on is able to tilt up and down (to a certain degree) because of a homemade heavy duty hinge on the top part. At the back of the axle/adjuster is a bolt that, when tightened will push the axle/plate forward, thereby tilting it. That way the bandsaw blade can be adjusted to ride in the center of the wheel. Easy in theory but very difficult if the wheels are not perfectly aligned.
The entire assembly - the block/axle(Block A) and another steel block(Block b) behind the block/axle - will be able to go up and down on two upright rods that will be welded to the frame. Thick steel bushings were welded to both sides of Block B to serve as, well, bushings for the whole assembly. Hard steel nuts will be welded underneath the whole assembly for a hard steel bolt to be threaded THROUGH until it (the bolt) rests on the bottom edge of Block B. THAT hopefully will complete a working bandsaw blade tensioner assembly.:)
Finally, a frame. Made from bailey bridge panel cross bracings. They are thicker than your ordinary 1/4" I-bars.The L-shaped part will be beefed up in the future.
Other pictures to follow soon:)
Peace!!

is the sole of that craftsman corrugated? nice find and nicer if it is... nice start of your wips. will watch daily...

Re: The making of a 14inch homemade bandsaw
Nice going Timber. Please keep us posted. My own bandsaw project is (I think) rotting somewhere behind my shop ... oh well. I assume you know that many bandsaw manufacturers post their equipment manuals online. You can gain a lot of insights from studying these. Some even have assembly drawings.

Only the sides are corrugated I think. Thanks bro.

I didn't know that sir. Thanks for the info.

Re: The making of a 14inch homemade bandsaw
Bro j2sip my apologies ... I mistook your project for one of Timbers. Great project. Keep those picture coming. Oh by the way, great find on the Stanley plane.

No prob bro. BTW, it's a Craftsman plane:). Thanks for the link.. My bandsaw will be powered by a 1.5hp electric motor. I plan to do a lot of resawing for guitar tops' veneer, etc i hope that suffices. For bandsaw blades, i still have to find branded ones ( carbide tipped).
Re: The making of a 14inch homemade bandsaw
hey, J2, where's the update? hehehe. you're slacking again huh? hahahaha. please keep posting updates. we love to see ingenuity at work.

Re: The making of a 14inch homemade bandsaw
I'm aware of that bro. Just like the proverbial mushroom eh?:) The truth is we lost our wi-fi connection at the office, and BRo's so slowww! I have to go somewhere else to upload photos and post in our beloved forum.
Here are some drawings of the bandsaw. Thanks to bro lncc, I tried Sketch Up and it"s a whole lot easier to use than the Autocad we have at office.
This was my original design. 2" G.I. tubing for the frame and a rather complicated tensioner.
Most recent drawing/plan.
