I do have a 230/ 380 vfd which i want to a-play it to the axact bridgeport motor. Can and how can i do that. Please!!!!

Great video, got a new subscriber!

Hi, I want to put 230v into my bridgeport, same as you have done. Do you put the 230 live &neutral[single phase] into the drum switch and then swap the 2 legs from the 3 phase from 415-0 to 220-0. If so what number terminals on drum switch for the 230V live and neutral?

Like very much ideotas no opere esta ma`q. Danger FUCKWITS, so many in every machine shop, Detail this BRIDGEPORT are good quality machine has mechanic feed with real gears. Well organize stand for clams , home made stand for collets , Dividing head turn smooth that mind the machinist oiling the headstock. Thank you good workmanship Saludos desde ARGENTINA.

nice presentation , please show the indexing gear calculations

Interesting. Very nice work

Great video! I have the same motor that I removed, and have been running a single phase motor. I'm now at a stage of wanting better control without constantly changing gear. Would you entertain carrying out this work for me for a charge? Here's hoping 🤞🤞

When I spoke to Ivan Law he told me that groove same as on the Dore Westbury mill was for oil. Nothing to do with raising the head.

👍🏻

cool!!!

Is there some sort of formula to know what gear should i put to the dividing head and the gear connected to bed?

It drove a rotary table not dividing head!

Omg did that in 1976 lol ! I've never seen that setup again. We cut a spiral groove on filter plate. Amacon Lexington Ma.

very nice but i need the formula of spiral groove gear ratio please

Nice video! All the time I was watching, I was thinking "This sure looks like the Accu-lock vice I just picked up!" Glad you were able to confirm that. I got the 3", I just have an itty bitty mill, so it fits nicely. I got the 4" originally, but it's just a monster, way too big for my little mill, lol.

Very interesting setup. Thanks for the great video! Possibly you could have used the automatic table feed to move the table and drive the dividing head simultaneously, if you would have driven the spindle of the dividing head directly. In your setup you gear up by a ratio of 1 : 13.3. The dividing head usually gears down by a ratio of 40 : 1. This results in an effective ratio of 40 : 13.3 = 3 (approximately) . So you could have used a gear train with a 3 : 1 ratio between the spindle of the x-axis and the spindle of the dividing head. This would take the worm gear mechanism of the dividing head out of the equation and remove a lot of friction from the system so that the auto feed drive would probably work. I am not sure if your dividing head allows this kind of operation. (My Walter head does.) However, milling multi start "threads" is not easy with the direct drive setup as you can't use the dividing plate any more. Just a thought.

well explained thanks

What you discovered at the end of the video is the classic re branding of bog standard cheap & cheerful eBay Chinese tools being sold at a higher price, sold by a seller in whatever country you're in. Specs by the seller will be translated from Chinese & embellished by the seller but will be just as untrue as the Chinese originals. They may claim they have some sort of control of Chinese quality control but they most certainly do not!!! The factory making these, & any other products, probably knocks out a 1000 a day so they're not going to be swayed by Arc selling 2 a month, or anyone else for that matter. I'm old & I've seen this in so many hobbies over the years, from wood/metal working to fish keeping & beyond that I can't count the amount of times I've been swayed by the "better" seller only to receive the same garbage!!! What always seems to happen though, is that the cheap eBay rubbish gets called cheap eBay rubbish, but the higher priced rubbish has all sorts of excuses made on it's behalf by the purchaser that doesn't want to admit being had by the short & curly's which only keeps the cycle going!!! Rant over!!!

Great Vidjeo Ian :)

Sir can you compute ,simplified gear ratio

Very cool to watch! Perhaps don't end with the spreadsheet - we're here for the machining content :D

Hanzhen harmonic drive gear , strain wave reducer, robot gear , over 30 years experience

it's called helical, not spiral

Thank you for the videos on this vice, trying to make do with an elderly abwood is giving me migraines so I'm going to give this one a bash - cheers!

Hi just did same to my Bridgeport and it runs fine only it seems to run as 4 pole does yours run at full speed at 50 hz

"not to be operated by f....wits" And learned a little English again. Thank you very much :-)

I stumbled across your video, saw the sign on your mill, and started laughing out loud. Great info shared via this video. Thanks for uploading it. kzbin.info/www/bejne/oWPNhI1pfpl8mqM

Very interesting, thanks for taking the time to do it. Look forward to seeing the rest of the build.

Well done mate. Where there is a will there is a way. Going to rig my Harrison M300 to do this. Nice vid.

Nicely “fettled”. I enjoy hearing your enthusiasm 👏👏👍😀

For the money, these vices are indeed very good. I’m looking forward to watching the follow up video to see your “fettling”. 👏👏👍😀

I like your danger sticker, very funny.

Love the "Danger" sign!

Would be interesting to see how much jaw lift it has, have you measured it by any chance? Appreciate that you leave the bloopers in the videos,.....makes me feel less stupid when it happens to me l.o.l. ;-)

Great review and improvements on the other video. Was looking to get one of these. The 5 inch looks a lot longer in in the flesh than the stated dimensions tho, so may have to go for the smaller 4" :-(

Cheap and cheerful, but I've not got any real problems or complaints

It took a long bar to losen the swivel base bolts, crazy tight. I did not worry about the finish under the movable jaw as figured it would help hold an oil film for lubrication. My crank handle was a rougher casting with some kind of black coating/paint. will improve it on the lathe?

Hi, watching this video a while after you have posted it. Has it made a considerable difference machining the face flat. plus you still recommend this vice since looking at one currently myself.

You are a braver man than me! I did a lot of reading up and decided to avoid a pancake machine at all costs due to the difficulty of rewiring the motor; found myself a regular J-head at a good price and on delivery .. there's no data plate on the (single speed) motor so I still have no idea how it's wired without mapping it out. D'oh!

Interesting video. I am in the same situation of having acquired a BP Series 1 with a pancake motor and need to decide how best to proceed. Change the motor and use a VFD, use rotary phase converter (not my preferred choice) or attempt your modification. What is not clear (to me anyway) is what is the base speed of the motor when run at 50Hz? 1400 or 2800RPM?

Excellent video. Great idea to use the lathe as a makeshift shaper. I might steal that idea for my lathe.

A great job... well done...

I'm considering buying such a milling vise and I wonder If you are still happy it. Please let me know. Regards Tim

Good stuff!

i plan on doing this soon with my cnc lathe and a macro. it has a servo on the spindle so it is infinetly index-able.

Great job condensing this into 7:32. I really like the comment about threading on your lathe, it cracked me up.

Nice work - I've done keyways in this style before. I was searching around to see if anyone had done female splines in the same way. I have a 6 tooth spline transmitting power to my milling machine spindle, and there is a fair amount of slop there, so I'm considering remaking that part. Thanks for the video! Cheers, Craig

CRAFTY .

I’ve done them on the milling machine the same way with the brake on. Used a dividing head. Did it with one cutter, just fed in a couple thow at a time. Worked like a dream.
