Eventually figured out someone had “Adjusted” the orientation of the idler wheel such that it was out of plane with the drive wheel. Obviously the blade can’t be tensioned while making adjustments to the idler, but it does need to be tensioned when checking with the straight edge as the frame will deflect somewhat when the blade is tightened. Took me a couple hours of messing with the adjustment and checking alignment, but it stopped the blade breakage and also stopped the blade from eating the wheel flange.
The upper end of the cylinder is closed by a compression fitting drilled out with a 8 mm hole for the piston rod. On dismantling the hydraulic cylinder and examining the flap valve membrane some hairline cracks were evident in the plastic where it covers the holes in the piston. The hole in the compression fitting at the top of the bandsaw hydraulic cylinder needed to be opened out to 10 mm from the original 8 mm diameter hole for the new piston rod but otherwise everything else is the same.
I’m wanting to build a hydraulic bandsaw mill but one thing I’m curious about. Serra,Montana ME 90….both these mills are HYD. driven….With the Log Master mill only the big mills used Hyd motors to run the Band wheels…. I am not hydraulic expert but I would assume you would loose a lot of power doing it that, and most of that power would be come heat in the hydraulic fluid that you then have to cool off some how. I saw a video of a homemade mill that used a hydraulic motor to spin the band wheels.
how to make horizontal bandsaw Related Question:
Can you use a horizontal band saw vertically?
Using a metal cutting bandsaw in the vertical position greatly increases the variety of work it can tackle. There are larger floor models that do work in both the horizontal and vertical position. There are also kits made to convert small portable bandsaws for vertical use.
How does a horizontal band saw work?
Horizontal band saws utilize a thin metal “ribbon like” loop with hardened teeth moving in a generally horizontal plane to cut metallic objects. The moving blade sweeps an arc thru a fixed cutting plane to produce repeatable fixed angle cuts. Only straight cuts at a fixed angle can be made on the horizontal band saw.
Why won’t my bandsaw cut straight?
Band Saw: Why won’t my band saw cut straight? When the band saw cuts crooked, a dull blade, improper feeding, loose blade tension or not using a work piece guide could be the cause. Use the rip fence or miter gauge to guide the work piece uniformly through the cutting blade to make straight cuts.
Why is my horizontal band saw not cutting straight?
Make sure the blade is running in the correct direction. On machines powered by three phases power so it is common to get the wiring reversed and have the blade running the wrong direction. On all vertical blade bandsaws the working portion of the blade should go down. This forces the workpiece down into the table.
Why is a horizontal bandsaw used to cut steel?
Horizontal bandsaws have a higher cutting rate, and they provide optimal squareness when needed. They also tend to have a longer lifespan for the blades, and they can cut bigger pieces of metal.
What is the difference between a power saw and horizontal band saw?
The horizontal band saw can cut the hardest metals but a vertical band saw can only cut pliable soft metals. The horizontal saws use a lot of power to cut hard metals while vertical saws only use less power.
What is a vertical bandsaw used for?
A vertical bandsaw, also called a contour saw, keeps the blade’s path stationary while the workpiece is moved across it. This type of saw can be used to cut out complex shapes and angles. The part may be fed into the blade manually or with a power assist mechanism.
Can a horizontal band saw cut wood?
It can cut multiple materials, including metal and wood.
Why are my bandsaw cuts wavy?
Re: Band saw Cutting Wavy Cuts. The clasic cause for wavy lumber is pushing a dull blade past it’s limits. Sharp don’t get it. On these low powered mills, the blade gotta be razor sharp..
How much tension should a bandsaw blade be?
For carbon steel toothed blades (cutting blades) this is typically 15,000 to 25,000 PSI. Slitting type blades typically are tensioned in the range of 12,000 to 20,000 PSI. In general bandsaw blades are never tensioned past 35,000 psi.
What causes bandsaw blade drift?
Drift is cause because the blade buckles under the load. You can see that by stretching a ribbon between 2 points and applying a pressure to one of the edges, it will turn sideway easily. A sharp blade and high blade speed will help a lot with that.
Why do bandsaws wander?
Tim Inman: Because band saw blades ride on crowned wheels, they always have a little “camber” angle relative to the vertical axis of the wheel. This causes the blade to tip a little and makes the cut “pull” to the side.
What is the difference between the two band saws?
Horizontal bandsaws are also better for cutting harder metals, while vertical bandsaws work best with softer varieties. You are more likely to see a horizontal bandsaw in industrial metalworking shops, while smaller shops and homes are more likely to have the vertical options.
What is a horizontal band saw machine?
A horizontal band saw is a type of band saw where the cutting piece stays stationary and the cutting head pivoting on one end cuts into the part by gravity assist. The Horozontal Band Saw in the shop is a Kalamazoo model H9AW, it can be used to rough cut metal or plastic (NO WOOD) stock to length.
