Can't think of a better way to start a Saturday morning before I start my honey do list than watching your video's. Thank you
👍
Good way to spend the time with the first cup of coffee on an overcast Saturday morning. Keep up the edutainment!
👍
In all my travels I have never seen a grinding jig like this,looking fwd.to part 3 where you do the graduations, thanks for all your eefforts🤗😎🤗😎
Thanks
My hand is up but only because I lost a dear friend who passed after a long, painful battle with cancer. He was kind enough to pass along a broach set he owned with a note " Now you won't have to borrow these anymore." Very sad way to get a beautiful expensive tool set. I am so blessed to have great friends . Thanks for Sharing ... Stay safe and well....
😂
A friend who will be smiling everytime you use his gift to you....sorry for your loss....keep em oiled and not rusting
I missed watching this on Saturday. I am pleased you found volunteers to make the drawings. I looked at all of them to see how each person presented them. Back in my drafting days (1970's) there was always a lot of comparing notes when working on projects if the company did not have specific standards for the way they wanted the drawings. I once drew a brake pedal pad for a 1972 Winnebago motor home. The engineer provided rough sketches and let me present it as I saw fit.
👍
A very useful accessory . I look forward to the rest of the series.
👍
Lyle, thank you so much. Wish I had your talents to show the projects I make.
Can't wait for part 4. A set of these came with my South Bend Model A that I recently acquired. Brand new, never used in the box they are. I'm also in the process of making a Double Ended ALORIS Indicator Holder TIPS #421 for my South Bend. Thanks Mr. Pete
👍👍👍
When I had my SB 9" I searched high and low for this jig. Very expensive the few that I did find on Ebay. I have a larger lathe now, but can still find this useful for my 5/16" square bits. Thanks as always Mr. Pete. Great video.
👍
Good morning sir, interesting as always.
Thank you again for this series. I am anxious to do this project.
👍👍
For such a grinding jig, I think you would be able to bore a larger diameter and then hand broach the corners of the square in the lathe. You don't need a full square to keep the cutter held while grinding. Not as beautiful, but should work just fine. As always, this is great stuff Mr Pete. Looking forward to the rest of the series. Cheers!
👍
Great project. Thanks for the video.
At 16:13 you elect to use a flat bottomed groove for the grub screw and state in part 3 that the original screw was not accurately located.
This feature is present in camera lenses (and telescope accessories) where these are attached to with a T-adapter. The adapter contains a V-groove and three pointed grub screws.
The screws are similarly offset from the centre of the groove. This causes the screws to force against the side wall of the groove. That way, neither groove nor screw dimensions are critical and the shoulder on the sleeve is only referenced against the face of the block.
Great explanation, thank you
You could make sleeve by milling a U shaped slot into a rod . The complete square is unnecessary as the top section is held by the set-screw.
Good suggestion
Thanks Lyle a good tool to have and a nice project
Really appreciate this one, thanks
Excellent video.Thank you.
Hey! I just found you on a 2016 vise video Bro!!!! So glad you are still around doing good!!!!!!
Thanks
It's coming along very nicely Mr. Pete.
I believe aVe made a square broach a few years back. He ground cutting edges and a slight taper on the starting end.
I didn't see AvE's version, but Clickspring did one, and Joe Pie showed how to make a tool to broach square corners.
"I didn't see a single hand go up" 😂😂😂😂 An old joke and told often ... much like "Who's on First" (but nobody knows what that is anymore) ... and I love it every time.
Abbott and Costello
I know who!
@@mrpete222 Probably the most requested and best loved gag in all of show business history.
In a pinch a boring bar ground correctly can be used with the carriage to shape a square hole. Been there done that. 🙂
True. Not many realize that the basic hole can be almost as large as the rectangular cutting bit. For instance a 1/4 inch hole would work for a 5/16 tool. The square corners don’t need to be very deep to properly position the bit. Doesn’t look as pretty as a full square but serves the same purpose. (Correction, I had this backwards. See my reply to Dave below).
@@ellieprice363 Are you meaning a 5/16 hole for a 1/4 inch tool?
Dale in Canada
@@dalemcinnes1834 Yes, I had it backwards. Start with a 5/16 hole and broach the corners square one at a time to 5/16. Best to blue the part and broach with light cuts to the layout lines.
@@dalemcinnes1834 Actually I still had it wrong. Starting with a 9/32 or even 3/8 hole would make it easier to broach the four corners. The hypotenuse of 5/16 (.3125) is
.442 so the tool would still be plenty strong.
Hello Mr. Pete
Just an idea or two I want to throw out there. Instead of soldering in the plug
a couple 1/8 holes drilled from the side with drill rod pins pressed in would also work.
I love high speed steel cutting tools. But due to really poor vision I can't freehand
grind worth a hoot. I built my own grinding system. I bought the cheap Horrible Freight
belt sander made a new table and jigs. Now I can grind tool bits just as good as factory
tools. I liked it so well I built a low-speed diamond hone for quick touch up sharpening
and making the radius on tips. There are times that nothing beats a good high-speed tool .
👍👍
Reid supply has machine tool sleeves by Sturdy Broach. They don't give them away but if you need them it's still easier to buy them then to try and make one. You can get them in square and hex.
Thanks
Chamfers are what separate us from the animals.
Time 12:30 You decibel for the bandsaw. Why not do the major cut by parting off? It's tempting to start making one myself.
MSC also has the square hole sleeves.
Thanks. So does McMaster Carr
Thank you for sharing. Enjoyed👍👀
Weren't looking hard/long enough to see my hand go up...
Purty shure that vee groove is there to allow for slight misalignment of the set screw position to vee groove relationship among the various holders and still pull the holder in tight to the block. But, to each his own I suppose...
I think you are correct
I was going to mention this too. I watched pt3 of this series before I saw this one. He mentioned this change he made in that video, so I watched this one to see what he said about the groove. Since there were only 65 comments, I went through them and found this one. I was going to mention that anyone who has a ShopSmith knows that they state in the manual that they put the point on the lock screw offset to the dimple of the frame on purpose to lock it in when you use it in the vertical position.
I made one of those years ago from Guy Lautards Machinist Bedside Reader....Now im going to make another one to hold my 5/8 HSS shaper tools just have to make it bigger and mill the bottom to a shallower 4 or 6 degree angle for my 24 inch Rockford Hydraulic shaper.....thank you for inspiring me to do so....the block i will use will probably be 3x3 or so
👍👍 I did not know that it was in the bedside reader. Do you remember which volume?
You had to ask me that hey Lyle!! I just spent an hour looking ....second bedside reader pg..88 and first bedside reader page 101....but i ordered many years ago from a mr N.L Snowden from peoria illinois shop made tools he had the complete block in a diagram...and i have that downstairs in my shop....i have all 3 bedside readers from Mr. LAUTARD AND #3 IS SIGNED BY HIM...i know he went thru a divorce and was always looking for more info. From him as he was a Genius in my humble opinion and i still use his readers for reference even today....i hope he is in good health and going to publish more BEDSIDE READERS!!!
I made your demonstration. with one alteration I made a steel insert . the same. size as the hole I ues an old Plug sockets with it square hole. heated it up to soften it for the fitting & cutting the peace in the expanded in to the slot once cold, it is not removable no pins then put in the lathe to size. les England when you going to [post the rest ?
👍👍
I'll be the first to hit like
Thanks
I drew up the plans for this but don't know how to get them to you... I don't have your email address.
Thanks for the tool design. I still grind high speed steel by hand as I was taught in high school in lower IL.
Thanks for continuing my education.
RobBob
Thanks Rob. I already have four sets of plans given to me by viewers. They are listed in myheap
@@mrpete222 Crowd sourcing. It is a great time we are living in.
Mr Pete. I can not find video 708. I am I blind?
Not available yet
Seems like a design crying out to be done in 3d printing. Medium precision, complicated, doesn't have to see hard service. The originals were in metal because that's what they had.
Yes, but remember the tool bed gets quite hot during the grinding operation
@@mrpete222 Perhaps a modification to include a piece of wet sponge would be called for. No worry about the plastic rusting.
