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.
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.
I had thought about whether the tee slots needed to go all the way or only half. In the end I decided to go all the way so I could bolt on a counterweight wherever I needed it if imbalance became a problem. Another reason was so I could alway add a back brace to a slender bar if it needed to be stiffened up. This is just a bar that goes from close to the end of the boring bar and then down to the boring slide at an angle, similar to a gusset. Ken
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.
Thanks. I have a second piece of plate that is the same as the boring bar holder plate (I got them cut at the same time). I got it so I could make another bar holder. I will probably drill holes in it and use it as a counterweight in the future. Even at 40 rpm the imbalance force did not cause any noticeably vibration so I was comfortable with it. However the force of the imbalance goes up to the square of the speed so I wouldn't be able to go much faster before it would be noticeable. Ken
Thanks Stovepipe. Rebuilding this HBM took 2 years and was a lot of work. When I got discouraged I would watch some of your videos to remind myself what the prize was at the end of the rebuild. Ken
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. 😢
About 12 years ago I was in a shop in Aberdeen that built tools for use in the oil industry. They had a Webster and Bennet vertical boring mill. They are hard to beat for this type of work. Ken
Thanks. I imagine they still make them but they are generally machine specific. Wotan built one for this HBM but unfortunately it didn't come with one. Ken
@@hmw-ms3tx - I often wonder the same thing myself . Allow me to elaborate about your Video. Their is a lot involved in making a Video. You connected all of them together in the proper sequence . Your Video is excellent - one of the best that I have seen . I'm in your corner . Keep up the great work , --- Jim
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.

Nicely done!
That's a good idea to make an XXL fly-cuter. It seems to work very well and leaves a very nice finish.
Hello Rusty. It turned out better than I had hoped it would, especially the surface finish. Ken
Awesome work, thanks for sharing, funny I was thinking why didn’t he countersink and then you show it!!! HNY
Thanks.
Cracking job there Ken . You are getting a lot of use from the HBM . 👍👍👍
Thanks Max. In the last 3 months or so at least 90% of my time has been on this machine. They are awfully versatile and a pleasure to use. Ken

Seems to work pretty ok.
Well done Ken that couldn’t of worked any better. Not much gonna stop you getting the job done
Thanks Steve. I agree, it turned out better than I had hoped for.
40 RPM with that mass, looked way faster and was a pleasure to watch!
It does look fast, especially when you are standing next to it. The finishing cut at 40 rpm gave a surface speed of 357 feet per minute.
Nice job on that

Is this a one man shop? The building does not look very old, nice concrete floor, etc. Have you done a shop tour video?
It's a 2 sometimes 2-1/2 man shop. I haven't done a shop tour video but I suppose I could some day. Ken

Amazing video
Thanks.
@@hmw-ms3tx welcome
Pretty inventive. Nice job! 👍
Thanks Tom.
Enjoyed!
Sounds like someone is regrinding some decent sized drills at 18:30.
Thanks Stan. It was my father in law grinding some parts in the background.
Nice work
Thanks.
@@hmw-ms3tx welcome
Now that is one serious tool. Do they still make the automatic feed style for facing or is that too old school?
Thanks. I imagine they still make them but they are generally machine specific. Wotan built one for this HBM but unfortunately it didn't come with one. Ken
You may add a counter weight next time.
mw1972 - Excellent Video - nicely explained . --- Jim
Thanks Jim. I'm never really sure if I'm boring people with these videos. It's nice to know some people find them interesting. Ken
