One of my favorite things about sat morning is a new Mr Pete vid. Thanks for all of your hard work and dedication over the years to shop education.
Wow, thank you!
Morning coffee with Mr. Pete nothing better ☕️👍🏻
Thanks for taking the time to make these videos Mr Pete
Hi Lyle. What an interesting design for a lantern tool post. I’m a little bit dense this morning and can’t understand how the post locks into the T slot to keep it rigid. The big nut adjusts the height only, leaving the post loose. It has to lock but somehow I missed it.
Yes, what he said! I have a Unimat and would consider making one but I don’t see how it locks down on the cross slide!?
locks from the top bolt pushing the tool down on the adjustment screw from above... the 1/2 bore lets the tool post float inside the adjustment screw which is locked between the bottom of the tool and the base of the lathe. The top bolt pulls the 1/2 inch post up pushing the tool downward which both locks both the tool and the t slot.
Got it, thanks!
Nice to see another tool build.We shared this video on our homemade tool forum last week 😎
Don't worry about screw ups on this job. It's exactly what you're supposed to do in order to adjust the tool hight😂
I know I’ll never make this, but I do enjoy the Unimat series as I have one and need to start playing with it.
Mister Pete is a National treasure.
Hi Mr. Pete I have seen many of these Unimat tool post holders and you have hit them spot on and maybe better. I will attempt to send you pictures of theirs.
Nice video. I am new to machining but have already found the aloris style tool post to bulky to get into some places, between the chuck and center. So I just got a new old lathe with only the aloris and was going to make a lantern style for when I need it. My new lathe is a '44 monarch CK12. 😊. Thanks for the video
Glad it was helpful!
nice... could also be used to make adjustment feet for leveling the machine or attaching to a bench, etc.
Quite an excellent video,mrpete.Thank you.
I enjoyed your video. The Unimat is a really cute little lathe! Nice toolpost
Great project. Thanks, Mr. pete😊
Thanks, Mr Pete
Very nice MrPete. I really like the elevation method. Scaled up, this could work for a larger lathe, say a 10" or 12" to get into tight spots.
Thanks 👍
Nice, thanks for the video.
I like my little Sherline Lathe. Thanks for the video!
I would love to have a sherline
@@mrpete222Sorry to reply here, cannot reply the standard way right now. Any adjustable height is a hundred times better than the shim method.
: - )
Thanks Mr pete great work !!
On a 3 week RV trip with poor Internet service. Have time this morning to catch up on missed Mr. Pete!
👍👍
love the idea !! hope to use it on a project, best regards Steve
Thanks for another video MrPete.
All the best.
Nifty little item.
Nice project Lyle
Frank
awesome!!
Love your videos Lyle👍
Glad you like them!
Morning Lyle ... 2
Nice idea!
I might start to make one... all the way from start though and metric
Thanks again
I might have part of the tool post. The base is about 3/4” dia. The body is about 1/2” dia x 1-1/2” long. The slot is 9/32 x 7/8. I can’t post a pic.
LIKE!!
Well done. That is a small tool post.
my schaublin 102 it's have a lantern type tool post.
Thought maybe it was a boring bar holder just missing the outside shell. I'm thinking I will build one for my SB 9" just because it's really cool.
👍👍
You can buy a small quick change tool post that fits the unimat lathes
Mr. Pete. They use this type of tool post on watchmakers lathes
Thanks, did not know that
🖖
I think I'll make that for the Emco compact 5 that I have, thanks!
👍👍
What keeps the tool post from moving?
The bolt is on the top of the slide and is squissed by the internal-6 on top (pressing the tool down on the nut and therefore on the hollow-bolt)
That part wasn’t covered. A setscrew through the post to tighten against the base is the only method I can think of that would work.
@@ellieprice363 No, not really. The whole original part is tight in the T-slot below.
I have an Unimat almost like this (the SL) so maybe it is easier for me to know how those work.
So, with pushing the tool 'down', you pull the original part up against the lower part of the base in the T-slot in the plate, at the same time tightening the tool itself to the nut and therefore the lower part of the hollow-bolt to the top of the baseplate.
Just a couple of movable pieces that move together to tighten things up. There is not much adjustability of course with this setup but not much is needed.
A drawing would make this clear easily but not that easy to add to an answer over here.
That would work only if the nut was thicker, not threaded, and was free to slide up and down. Which of course would defeat the whole purpose of an adjustable tool height. If I made one I would put a 6mm or 1/4-20 setscrew right down through the center to lock against the base of the T slot.
If wanting an actual rocker did you consider just altering the nut?
1/2 drill the threads away, don't saw off the top, turn the extra to 3/4 diameter and slot the top for the tool blank & rocker (in this case with a 1/4 " x 4 " diameter cutter - the rocker bottom arc would be a 2" radius).
Would the screw tighten enough to hold the tool blank?
Give it a try
These "suitcase" lathes are great little tools for smalls...I have four of them.. I've had the DB200 for about 50 years...would never part with it...
👍👍👍
You asked for photos. I have a lantern post for my Unimat and am going to take some for you. How should I send them?
Thank you. You will find my mailing address in this RUclips video. Here is the title, search for it.
Spring special, Mr. Pete machine shop video courses
Mr Pete I'm surprised at you.
If you try and use that lantern in the compound without using a teenut in the slot! . otherwise you're going to tear out the underside of the compound slot as soon as you try to tighten a tool in that holder.
That’s not gonna work.
