I worked for a company in the early 70's that built the type of beams. We used a shop made jig and wedges and a sledgehammer to bend them and then tack them every 6 inches. They were on a tilt table when final welding with a dual wire sub arc machine using 3/16" wire.

How did you indicate that by using the body of the live center?

Fosdick, More More speed, and Weiler have three bearings in the spindle for boring heads

No dowels into the existing concrete connecting to the rebar cage?

Good one Ken . I watched it twice & i think you pretty well hit the nail on the head . Cheers 👍

Oooooh I doo like that HBM. So much reach. Nice work sorting short run production for this tail stock..

Great discussion and build!!!!

Good job a lot more to them than you would think. and to much work and time in them to not work properly 👍👍👍👍

Very interesting project. Is all the bending done cold or is heat applied. What thickness is the web being bent.

Quite the process there. Thanks for walking us through it.

I would be very curious as to what kind of system the company was/is using before this. Thanks very much. Regards.

There is indeed a lot of thinking hidden in that part.

Seems like you should have just turned the tube,and been done with it. Too many ads greedy utube scumbags getting as bad as tv

Love your videos ive ran a lucus 5 for 30 yrs, i wish you would so more of the set ups, customers has no idea how long it takes to get something like that ready to start to machining.

Soy de Guatemala que precio tiene la maquina

Lathe को काम ना होए हमसू

That looks identical to how my DeVlieg jig mills clamp the tools.

Nice to see an old British lathe still doing a good job. I would say the finest lathes in the World are British and American. The Japanese did a few nice ones and the Italians.

The spindle taper looks terrible

That is a good set up on the draw bar . I think i will have to bite the bullet & make a heap of the Bayonet adapters for the NT50 tooling on my mill & keep running it . It's just a bit of a janky method to grab the tools , but works . My one has the electric interlocks & a time delay before it will let you start the spindle . Cheers Ken , Thanks . 👍

That draw bolt system seems robust but a bit complex. Fine if it’s working as designed. You must have bought an INT40 holder with M16 thread, still got them? I thought about just clamping that HSS chamfer tool bit in for retraction through the hole… Save a second or so but what could possibly go wrong! Hahaaa. That HBM has proven useful.

Excellent description of the de-clutching mechanism. What a great system to prevent whoopsies. The whole system is pretty cool really. And those vise jaws are a interesting concept. Stop pin bores by the looks of things. Did you discuss those in a previous video?

Did you make any progress on making up a nose for supporting the spindle yet

My boring mill uses a MT 4 spindle I wish it had 40 taper . I have thought about making an adapter from MT4 to 40 taper but never got it done and some people said it would not work. Are you looking for 40 stuff ?

I bet you was really happy that it had that power drawbar 👍👍👍

🧐 interesting

@ 33:30 Did you have those previous experiences with boring? Because if you think about it. A 45 degree angle will diffuse the force 50% sideways and 50% into the spindel. Creating more sideload. While at 15degree you only have about 25% of the force as sideload and 75% of it going straight into the spindle. Just a quick thought I had.

You call this a large lathe? It’s small when you don’t have to use a jog button for dialing in my friend.

Seems to work pretty ok.

cool, nice to see different uses as a beginner

Nicely done!

Excellent job, with some smart tooling. TOP.

Quite the boring "bar." But when you think about it, you only need the t-slots on one half of the slide.

Cracking job there Ken . You are getting a lot of use from the HBM . 👍👍👍

You may add a counter weight next time.

My understanding is that the majority of PTO accidents involve a bolt or something protruding from the shaft. Keeping everything low profile on rotating parts is a good idea.

Awesome work, thanks for sharing, funny I was thinking why didn’t he countersink and then you show it!!! HNY

Now thats a proper boring slide, i have one similar to that i mount on my facing head for overturning pump flanges and press bearing journals. Not to be a pain in the arse, but you May want to add a counterweight, diametrically opposed to your tool though. Thats ALOT of load on your spindle bearings. Just bolt a 246 block or 2 on the other side. Fantastic work there brother, real good showcase of run what you brung.

Amazing video

Nice work

Now that is one serious tool. Do they still make the automatic feed style for facing or is that too old school?

Pretty inventive. Nice job! 👍

Enjoyed! Sounds like someone is regrinding some decent sized drills at 18:30.

Is this a one man shop? The building does not look very old, nice concrete floor, etc. Have you done a shop tour video?

That's a good idea to make an XXL fly-cuter. It seems to work very well and leaves a very nice finish.

Well done Ken that couldn’t of worked any better. Not much gonna stop you getting the job done

40 RPM with that mass, looked way faster and was a pleasure to watch!

Nice job on that

When I first started working as an apprentice at GKN Sankey Wheels UK we ran 36" and bigger Webster and Bennett Boring Mills. Like a lathe but standing on its headstock and the slides vertical. Making wheels for earth movers and fighting vehicles. They would have eaten that job in 1/2 an hour. The company has closed down recently and I wouldn't mind betting they scrapped everything. The sight is about to start building houses. Pretty much the same story for all of British industry. 😢
