<\/a>Then if you want forward\/reverse you need the KB #9339<\/p>\n
I opted not to use an on\/off switch, because the foot pedal will fill that role, these controls have a “Run\/Stop” function that I wired up to the on\/off switch on the foot pedal.\u00a0 So that when you depress the pedal it is sending\u00a0 the “run” command, and when you let off it is sending the “stop” command.<\/p>\n
(The foot pedal is controlling the on\/off even when you are using the panel potentiometer)\u00a0 You need a 6 wire cable to run the foot pedal.<\/p>\n
For some reason the wah pedal on\/off switch would not work with the “Run\/stop” inputs, so I had to use the line switch inputs L1A and L1B instead.<\/p>\n
Also, the KBPC control is really meant for bigger motors than 1\/17hp, so to run that small of a motor you have to cut out the built-in horsepower resister and replace it with a 1\/4hp resistor, then the motor amp jumper is reduced to a tenth of its labeled amps.<\/p>\n
The inside of the control is getting pretty crowded at this point–and it is a challenge to be able to close the lid.<\/p>\n
<\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n The spindle bodies are just 2″ pipe, The 30 tooth gear I heated up and pressed on the unmachined portion of the spindle, for a permanent attachment.<\/p>\n The motor mounting plate I ended up CNC machining, because it had to have slots, and holes, and a big center hole all accurately dimensioned and located.<\/p>\n I whipped up a chain guard sort of after the fact.<\/p>\n The grounding is through a strap or two of 7\/8″ flat braided copper looped around the spindle,pulled tight, and bolted to the frame.<\/p>\n <\/p>\n <\/p>\n <\/p>\n After attempting to weld freehand I found that it was near impossible to stay in the same spot while the part rotated, the start and finish of the weld wouldn’t meet up at the same point.\u00a0 So I decided to make a horizontal bracket to\u00a0either rest your arm on while welding, or to clamp the torch to.<\/p>\n <\/p>\n <\/p>\n Works great.\u00a0 My little 140amp Hobart did not have the power to do adequate welds with it though, so I had to upgrade to a 210amp machine, and that is much improvement.<\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n After having built 5 of the square tube frame bodies, I think there is a lot of room for improvement in the design.\u00a0 Nearly all the professional benchtop positioners are built with 1\/4″ plate bent and machined, and if you have the means to bend 1\/4″ plate that would be a better option.\u00a0 Because there is an excessive amount of welding with the square tube, and getting everything flat, square, and accurately positioned so that all your holes line up is not easy.\u00a0 Whereas with the plate, there would be very little welding and the layout would be simpler.<\/p>\n All of a sudden I wanted a welding positioner.\u00a0 It has never come up that I needed to rotate a part and weld on it at the same time, but I started working on a design for such a device anyway, then someone posted one on craigslist.\u00a0 They had […]<\/p>\n","protected":false},"author":1,"featured_media":104,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"gallery","meta":{"footnotes":""},"categories":[4],"tags":[],"class_list":["post-84","post","type-post","status-publish","format-gallery","has-post-thumbnail","hentry","category-metal-related","post_format-post-format-gallery"],"_links":{"self":[{"href":"http:\/\/mike-stalkfleet.com\/blog\/wp-json\/wp\/v2\/posts\/84","targetHints":{"allow":["GET"]}}],"collection":[{"href":"http:\/\/mike-stalkfleet.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"http:\/\/mike-stalkfleet.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"http:\/\/mike-stalkfleet.com\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"http:\/\/mike-stalkfleet.com\/blog\/wp-json\/wp\/v2\/comments?post=84"}],"version-history":[{"count":10,"href":"http:\/\/mike-stalkfleet.com\/blog\/wp-json\/wp\/v2\/posts\/84\/revisions"}],"predecessor-version":[{"id":209,"href":"http:\/\/mike-stalkfleet.com\/blog\/wp-json\/wp\/v2\/posts\/84\/revisions\/209"}],"wp:featuredmedia":[{"embeddable":true,"href":"http:\/\/mike-stalkfleet.com\/blog\/wp-json\/wp\/v2\/media\/104"}],"wp:attachment":[{"href":"http:\/\/mike-stalkfleet.com\/blog\/wp-json\/wp\/v2\/media?parent=84"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/mike-stalkfleet.com\/blog\/wp-json\/wp\/v2\/categories?post=84"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/mike-stalkfleet.com\/blog\/wp-json\/wp\/v2\/tags?post=84"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}<\/a><\/a><\/a><\/p>\n<\/a>The frame is pretty straightforward.\u00a0 The only tricky thing is getting the all hitch pin holes lined up properly.<\/p>\n<\/a>with a separate machined and threaded nose portion.\u00a0 But the body of the spindle measured 2.003″ OD, and the pillow block bearings were 1.999″ ID, so after much dicking around trying to heat the bearings in oil, and freezing the spindle, and attempting to press it with the hydraulic press–I had to resort to machining .004″ off the spindles to be able to get them on the bearings without destroying anything.\u00a0 Had to acquire a 2″ bullnose live center for this purpose.<\/p>\n<\/a><\/a><\/a><\/a><\/a> <\/a> <\/a> <\/a> <\/a> <\/a> <\/a> <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"
