Proof Of Concept Hydraulic Bandsaw Feed Rate Limiter

[mklotz]

Very clever, as usual, Rick.

For folks without sinus afflictions, probably the most commonly available bottle would be the ubiquitous two liter soda/water bottle. A 'calibrated' simple hole in the cap used in combination with the down pressure spring on the saw should provide the correct feed.

I have a tube from an HF 13" tire that already has a leak. I'll have to give that a try.

I wonder if something like modeling clay or duct seal could be used; varying the width of the piece being crushed could control the descent rate.

Oh, and you have good taste in bandsaws. Or I do. I have exactly that model Enco bandsaw. One of the most useful tools I ever bought.

Thanks Marv.

That bandsaw was the first machine I bought for my shop. Never had any trouble with it although am dismayed by the rising cost of blades.

I visited my local Home Depot and bought the Air Shim, gate valve, and a needle valve. I found the needed tubing in my junk box. I can get a nice, controlled feed rate with it but do have to use the attached squeeze bulb to pump it up. Not as handy as the plastic bottle where I just partially unscrew the cap.

I gave more thought to your suggestion of using a polycarbonate bottle. The bottle I use is polypropylene and designed to flex. The pop bottle will deflate nicely but will not spring back and will fatigue leading to cracks. I'm looking for an alternate to the nasal bottle.
