Great Job friend! Wow, that big boring bar is a monster, and cuts a fine finish. You managed to get a very rigid set-up which really paid off. Great to see your shop and dig the way you do things. Good fortune for you!

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.

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 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

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

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

Nicely done!

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

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

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

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 work

Thanks Tom.

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

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?

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

You may add a counter weight next time.

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
