hydraulic downfeed

 

i'm wanting to make a hydraulic down feed for my bandsaw...i've read that some guys use a screen door closer...has anyone here tried this?

Hi

There are early references on this site of people making hydraulic downfeed from a screen door closer, if you search through the picture in the photos section maybe you'd find one,?but whether you would choose to do that, given the other options, is a different story.

A screen door closer is mostly an air spring with some hydraulic dampening - you need the hydraulics but not the air spring.? If you can get it apart (they're mostly welded shut so you'd have to cut it apart and find a?way to?fit it together again), it has all the bits there to modify.??

The simplest is to buy an OEM replacement from a manufacturer. Homier used to do a kit for about $35 back?5 years ago for their swivel based saw (swivel based 4x6's seem to have downfeed controls were the std ones don't),?and all the 7x12's have them as spare parts, you'd need to check.

Then air cylinders are the next best choice mainly because they're cheap and you can get all the parts that screw together.

There's a long post on hydraulic down feed on?20Jan16, msg#14641 (if you're in the Conversations tab of the 4x6 site there's a box at the top?to enter the msg # into to take you there direct) - jv
 

I've published an article about this. ?It's in the November/December 2018 and January/February 2019 issues of Home Shop Machinist. ?Total parts cost is about $25-$50. ?Machined parts are very simple, nothing precision. ?Lathe needed, mill useful but not required - can do what's needed on the drill press.

- John Herrmann
 

For those of you who are interested in my downfeed article, you can get back issues of Home Shop Machinist from the publisher, Village Press. ?Here are links to the two issues:

Several forum members have asked me for copies of the article. ?I'm not sure if I'm allowed to do this, as the magazines (and articles included therein) are copyrighted.

I have sent an email to the editor, asking for clarification. ?If I get the OK, I'll be more than glad to send out scans of the article pages. ?I'll let all of you know as soon as I've heard something.

Shouldn't be a problem if you don't charge for the copies. Wouldn't be a problem at all in my case as I've already ordered the magazines. Just have to wait the 2 - 4 weeks while they come in snail mail.

Copyright enforcement is still valid, even when there is no payment.

Copyright does not mention charging.? It doesn't matter if you give out copies for free or even pay the person to take it, you are STILL violating copyright law.? It's also up to the copyright holder where, for how much and even if the work is sold.? That's why you still can't give out copies of an out of print book until the copyright expires.

This also goes for the 12 billion people who grab stuff off the Internet like photos every day.

How about good old fashioned ethics?

The magazine makes its money selling magazines.

Hard to do that, if people splatter their articles all over the net.

So, if it’s not in the public domain, don’t put it there.

I have some pieces of 2x4 that I put a V-groove in on the table saw.? When cutting conduit or thin-walled tubing, just sandwich the workpiece between the 2x4's with the wood extending about 1/8" past the cut on both sides, and let it cut.? The wood keeps many teeth in the cut, and it's free.

Regards,
Ed
