Horizontal Boring Mill Restoration: Fabricating a Drive Dog Plate for the Spindle 

Thanks for sharing. Need a tool, make a tool, build a project.

Good morning Keith! 😊

nice ... (would have to have faced that plate!)

I assume this weld-up was what inspired you to buy a rotating weld positioner :) Or...did you have it already but didn't it fit?

Looks like a good solution to the problem.

Thanks for taking the time to post the video

Drill some circles at the end of your horizontal flex cut so the cylinder doesn't crack from repeated flexing?

i would definitely of faced that before boring it ...just because it was annoying me! chuckle

Keith, Great Video! I have been one of your subscribers for a few years now but have been too busy for the past 6 months or so to tune in to RU-vid. You got thin! If it was deliberate then congratulations - otherwise I hope you are well!

Would have been a good job for your new welding turn table

Always a pleasure to watch.

Nice work Keith 👍 I like it see you next video 😉

I would exclude the grub-screw, for if it slips, it would damage the spindle seriously. Rely instead of the clamping-force alone.

Keith I do believe your welds are looking better and better!

thank you Keith

Can't wait to see them put to work. In hunagrian we call these drive dogs lathe hearts actually.

Kieth, you're looking good buddy. Keep it up and you're and inspiration.

I am wondering why you did not use your new Vevor weld positioner to weld the pipe to the plate.

This helped me a lot. I had been pondering how to solve a problem where my drive dogs wouldn't reach over a live center I wanted to use. Thanks Keith!

Most excellent.

Now you can use the machine to "turn between the centers" like a lathe.

You're looking in good shape!

That is a nice job but I was surprised that you didn't face that plate.

GREAT planning and execution.

I would suggest putting a stop drill hole at the end of the cur across the diameter, in use that will be a stressed hinge under cyclic load nice place for a fatigue crack to propagate from. Too late now, but hopefully the amount of use the part gets wont be enough to be an issue.

Morning from the UK Keith glad progress is being made up to actual use time, shop dog loojs happy too❤

Thanks for sharing 👍

Another fine job Keith, keep up the good work!

Your explanations are always great, but this fabrication was on another level. I have a little machine shop experience but figuring how to make this was way beyond me- I just learned a lot.

Another interesting video professor

This would've been the perfect project for your new weld positioner. 👍👍

Good morning.

This is such a cool and engaging project. Thanks!

Thank you for sharing. Very nice, always enjoy when you make something new for the machines in your shop. Enjoyed the video.👍

That's super awesome! Your video inspires me a lot.

It's looking good! I am looking forward to seeing you complete a job with this machine. Thanks for all your work.

Hiya Keith

You mention a drive dog and a dog walks into the shot…😂

6:08 ShopDog! Lordy, those ears! 😁

Gday from Australia Keith

time to feed it a project.

wow, you lost so much weight, keep good care of your health!

Good morning Keith. Great piece of tooling for the mill. Thanks for posting.

if was makeing the drive plate i would bore the face plate center a little bit biger then weld the plate to the pipe on the iner then re machine it

Thanks as always for the fantastic detailed video. I just need to find a new place and get a big barn for some big iron!

nice stuff

Hey bud looking better! Hope heath matters are and have been corrected. The weight loss is a good look for ya as well as a healthy thing!!! Go Keith!

Great journey thoroughly enjoyed it. Best wishes...

Nice job Keith 👴🏻👍

KEITH, GREAT JOB, GREAT VIDEO, PET AND OR TELL ALL HELLO...

That tube looks like a piece of Sherman tank barrel.

Nice design and build. However, knowing how I am, I would have had cut the face to true it up as well. It looks wonky with the face run out to me. But since it isn't my project, if you like it as is, that's all that matters. Thumbs Up!

As always well done. Could surely be used on a mini lathe too. Inspiring!

@ 1:28 Puppy Dog! 🙂

Nice job, Sir!

If you use a 3/8 th drill for the first hole, you can easily follow it up with a 2” drill and skip the others.

OK Keith. Give the W series tools and inserts a go. They're brilliant for interrupted cuts. However!... every time you use the plate, it's going to be waving about. For the sake of another two minutes machining you could have faced off the outer side and produced a beautiful looking piece. At some point you may need that outer face to be perpendicular to the machine rotary axis. Thank you for taking the time to make these videos.

You look amazing Keith!

The only question is did the Rotary Welding positioner come before or after this video or was it partly the 'reason' for it 🤣

Great idea Keith. Nice work. This should work very nice. Thanks for sharing. Take care, Ed.

Thanks for the education!

Missing a piece? No problem... I'll just make it.

Face plate most know it by. Face plates have holes and slots. For mounting upon or driving a dog.

The makings of a great joke: "A dog and a drive dog walk into a boring machine shop ..."

Magnificent :)

ready for work keith!

The mike set up sounds pretty good. Thank you. So annoying to us mere mortals, turn your head and the volume of your voice would double or disappear. Hope this fixes that issue. Always hit the like button anyway. It's all good.

Great video wish I had your skills thanks for sharing

Are you going to use the Horizontal Boring Mill to machine the inside bottom of the Steam Engine Pony Motor?

Looks great. I like the TLAR engineering

Another way to make the hole in the plate would be to use a hole saw. You would have a 1/2" thick slug that could come in handy for some future project instead of turning it all into chips.

What's the name of that white coyote sneaking around in the background? It looks like a real stickybeak.

I am surprised you did not use the Vevor cake rotisserie/turntable to weld it? Very anxious to see the big boring machine run! Frank

I'm betting this "upcoming project" is that fire box or, that pitted locomotive related project that Abom used his shaper on and I think Brian block had a crack at it also

liked for algorithm

I wish I had a dollar for every time he says “it’s not critical”.

Not sure why you didn’t use your welding positioned to weld the plate onto the tubing?

Any update on the Stoker Engine?

Im surprised you arent using your welding positioner.

I'm guessing this was done before he got the new weld positioner. Would have been a good job for it.

assume you did this before you got your Vevor weld positioner.... also curious why you didn't turn down the end of the tube a little, bore a hole in the plate for the tube to fit, then weld and bore tube?

How many amps did you use to weld the faceplate?

What happened to the new weld Positioner

Keith, what's the name of the puppy and what breed? The horz. mill is coming along quite well, can't wait to see it in action. PS You should have used your positioner to do the circular welding, and what about a counter weight for clamp ears.

Drill a hole in your plate and weld it to a MT 5 center. Finally going to finish that firebox.

What is your dog's name?

I assume this had a long thought process, "Ok that makes sense but let me think about ... "

DOG!

If only you had a machine to rotate that part while you were welding it…

Let me guess. Line boring a cylinder.

😛😛😛😛❤❤❤👍👍👍👍👍👍👍

Dogs ever get chips in their paws?

push mig never drag

? a new pup. He/she is definitely white.

Round part ... new rotary table ... why not use that Keith???

Keith CAD = chicken scratch

ffs Keith .... square the face up ..even by your standards its a mile out ..
