Unfortunately, I think all that is above my skill level. I ended up buying a new (cheep) power feed. I just have to get it mounted now. Thanks for the feedback!
Thanks for the feedback. One of my other viewers also recommended getting rid of the blocks. They pointed out that with vibration, one of them could crumble. So I have it down on the floor yet. I thought that the mill suddenly tipping over was not the best idea! Ha! Thanks again.
Difference between the X - table end plates, is the right side bearing floats axially on the lead screw, the left side plate - bearing can be adjusted for axial play (thrust) of the lead screw to the table.
Thank you for this. Do you know *why* only the left side is fixed to the table, leaving the right side to float? Perhaps if the lead screw to expand or contract, it would lead to buckling of the lead screw otherwise? Thanks for watching.
@@KevinToppenberg Honestly don’t have a verifiable answer. Maybe putting the lead screw in tension, might lead to additional alignment issues and accelerate nut wear? Seems to me that most lead screws I’ve encounter are only compensated for thrust from one end. Maybe a general engineering practice?
A very good line of thinking, but i would expect to at least see a spring of some sort in such a scenario... Tho, i guess that this isnt a precision spindle but a leadscrew bearing bore, so my first expectations may be based on a much more demanding scenario... A good idea anyway...
I have since purchased one of those "Wing Ding" Chinese power feeds. With the light work I do, it will probably last several years. It would have been nice to get that heavy duty one working. But such is life. I don't know much about the Vevor brand. Is it good quality? Thanks for watching.
@@KevinToppenberg I do not know personally, but have seen a couple of videos where people do seem to like them. Mr Pete did get one with a issue (ran too fast), so you might want to bench test before installing. BTW, he was installing on a Bridgeport, so it might give you some ideas for the installation
Crazy project? M8, restoring a bridgeport is as normal as you can get in the world of machine resto... Also, that bearing retainer got its backside blown out by excess amounts of torque the prior owner applied to those capscrews... Tho, i cant call them an idiot, i just had a moment of moronism myself when i was shifting machines yesterday evening... Put a bend into a handle by lifting the machine too close to another machine... My excuse is - I was dead tired, it was the 16th hour of working since 6am, so i had a moment where my thinking wasnt at 100% and shit happened... Luckily no real damage was induced thereby... Oh, and its a jig grinder/edm orbital sinker... That`s why i was moving machines again... So if you think that a bridgeport is crazy, wait until you snag a moore no.2 or some majestic monad of that kind... And hey, a moore no.2 would technically be related to your bridgeport, as moore is to bridgeport what brabus is to mercedes... Nice work at any rate, the mistakes and lack of success regarding the powerfeed notwithstanding... I definitely would not have used alu for that bearing retainer, but that is just my fanaticism regarding contact corrosion of dissimilar metals... Brass, steel or cast iron would do, but alu is reserved for other alu parts in my book... The powerfeed on the other hand would have been a good thing to add - were it not determined to refuse that attempt... I definitely dont like that plastic motor cap in it... It really shows a remarkably high level of cost cutting that isn`t really acceptable in the world of industrial componentry... I like the good old mechanical powerfeeds that rely on simple chunky relays and excess of wiring to deal with stopping, moving and reversing along with rapid feeds... Less adjustable for sure, but near indestructible and easily serviceable if any of the mech switches or relays gets damaged... What`s worse is that this isnt even a really sophisticated modern design, yet it is modern enough to suffer the flaws of engineered lacks of longevity and durability... Tho, that design really is tricky, as the thing has to house a motor and the wiring, yet it has got to be at least somewhat manageable and confined as not to look like a massive hernia... It would be nice to see someone with more passion for such things(CAD) than myself - designing and making a system that would fit under the table and mount onto the carriage itself if possible, perhaps a complete re-engineering of the nut-block that would allow a single motor to feed either x or y axis by spinning the nuts while you lock the leadscrew with a simple mech. pin-stop, and which would mechanically lock the nuts in the same manner(or via worm-gear drive) for you to be able to handfeed when you release the leadscrew pin... I already have a simple design in mind as im writing this, but im obliterated after yesterday, so i wont be putting it on paper, maybe at some point, as that would be a decent product that would not put bending loads on one end of a table, but as said, not today... Kind regards and best wishes! Steuss
Steuss, I'm glad to hear that your machine moving adventure didn't end badly. Thanks for the thought you put into your replies. I have seen some of the old Bridgeport brand and they are massive. And they are still working.... Ha! Best wishes, Kevin
@@KevinToppenberg Yeah, the oldies of their kind and kinly ilk are really amazing masterworks of mankind and are worth restoring to their former glory or even higher standard than was easily possible on a large scale back in the day, especially as a single operator/shop owner that does it from love for machines and pleasure of taking care of such gems... Regarding best wishes, i think i also got a job along with that machine... A machine restoration company job no less... The fine gentleman whom i bought the machine off of worked there before going private and offered to recommend me for the job... This has got to be the first time i am excited about a formal job possibility... And how would i not put thought into comments, I never watch people whom i can`t appreciate or wouldn`t offer to come to my place for some time as a guest, furthermore, i don`t watch any content that doesn`t resonate with my passions, so the comments are merely spontaneous responses to quality stimuli... All the best and kindest regards!
Just curious, why didn't you rotate the bearing retainer by 30-45 degrees, redrill for the screws and reuse the original part?
Because that would have been too easy. LOL! No actually, it is because I didn't think of it. Kind of a 'doh!' moment on my part. Ha!
I would check the mosfets, diodes and cap on the board. Resistors usually don't fail so easily.
Unfortunately, I think all that is above my skill level. I ended up buying a new (cheep) power feed. I just have to get it mounted now. Thanks for the feedback!
I would get rid of the concrete blocks under the bridgeport shop looks nice though

Right hand side bearing floats. Only one bearing. Keeps the screw from bending due to thermal expansion.
I was just wondering this when looking at another comment. Your explanation makes sense. Thanks! Hope you are doing well. :-)

Well, if it's any consolation, Vevor does have unit available at a pretty reasonable price

Holding long chips is the easy way to loose fingers!! avoid it..if it stuck will cut fingers in half... :(
As I watch back on footage I have made, I see all these crazy things I have done. I'm trying to learn the easy way -- before I hurt myself!
