    remake of my 7 ft folding break

    this is not a new tool but it will hardly resemble the itself.
    I made this about 3 years ago to do 1 little job then after finishing the job it got put on the back burner for completion
    7 ft metal break
    So for the past month I have been time allowing making tools and parts to finish it up I still might not get it completed as much as I want but at least it is now far enough along to be considered work in progress plus it is right in my way which makes me more inclined to do some work on it .

    As you can see it was about as rudimentary of a metal break as possible
    So first things first the gate or swing beam had to go and a top clamp was needed

    then a new gate had to be made

    next the parts for the pivot. I have a large stack of these I think they were once used as casting molds that a guy used to make small train wheels
    the bore was too large for my 6212 bearings so I welded them up then machined them out to the depth of 2 bearings

    Some left over cut offs from the Forklift carriage will become the mount base which the gate pivot mounts will bolt to

    you can see how tough Caterpillar metal is by the sparks at least 120,000 PSI tensile

    this build or I should say rebuild so far has required me to make at least half a dozen new tools and parts of the build are shown in 8 or 9 other threads and some tools required other tools to be made before they could be used to make the parts this is at least a partial listing of those threads you may note some of the parts being processed to get the build to this point I am sure more will be required before I can call this a real machine
    stand off blocks
    21/32 x1/4 drill / transfer punch guide
    http://www.homemadetools.net/forum/t...5-8-11-a-63210
    Alignment cones 2x2.75 x30°
    torch head w circle cuter trammel or compass marker
    Set up block
    1.75x12" boring bar.
    A different style boring head
    Boring/ grooving bar
    not a tool yet only a part
    I will be using the eye end of leaf springs for the top clamp pivot the reasons will be made clear in future posts
    first off I removed the urethane bushings and replaced them with a pair of hollow piston wrist pins that just happened to be 1/250" OD and 1.000" Id the half round pieces were made from 2 3/8OD oilfield pipe
    remake of my 7 ft folding break-20170813_125813.jpg
    this is how they will be fitted together on the machine the half round will be welded in the end or the clamp arms then the arms will be plated with 1" holes for a pin to become the pivot.

    With many other things to do I don't get to spend as much time working on this machine as I would like
    However today I did manage to spend a little time on it. I now have 1 side of the main hinge for the top clamp complete and the other ready to assemble an dweld.
    I drilled and ground grease pathways in both the spring eye and the pivot shaft. since the shaft is fixed to the top clamp this makes the cup holding the spring eye and the pivot shaft rotate around the spring, which meant I needed grease both inside and outside of the spring eye.

    Kind of hard to see but grease was forced out both ends of the eye inside and out

    I have the other side welded up now on to making the cam lock assembly for the top clamp. but I thought I would share some drawing pics of my design This is a close approximation of how it will look when completed
    And later on I may add hydraulics to it

    Looks like it will be a very rugged and useful break. What is the anticipated capacity?

    On another note, the cad drawings makes me ask if any one has had any use for sketch up. I tried but found that w o instructions it was a smoke grinder waste of time.

    Thanks for the post.

    Man I've tried sketch-up Coral draw. solid edge Auto cad designer for me I guess I'm too dense to put the effort into the learning curve Or it maybe because from the very first time I powered up my own PC I have had solidworks on it, and since I can no longer afford the upgrades I'll just stick with my 2013 version
    the target capacity of the machine will be around 10ga for full width but as much as 3/16" for half width or less But I will be happy if I can only form 10ga at 6ft wide sheets.
    It's kind of back burner right now while working on green house and trying get garden in.

    At times I work for my brother in law, he has 9 greenhouses if I count right from memory. He has several different styles, from home built wood Cornell style at 27 by 75 to salvaged 21 by 40 short squat hoop house (a real snow load issue with these, that's wy they are salvaged) he just started crops about 2 weeks ago, still getting in plug orders. Love seeing spring in the houses before it comes outside. The soil where he is is a sand clay mix that holds water terrible. The Cornell houses are having frost heaving problems with the posts, broke a rather, will have to do a drainage project sooner or later. Oh well.
