Jig Grinding the second ear square and parallel with the first ear.

[@ronaldgraziano5170]

You are such a nice and knowledge person.. I am new to machining and your show has been most helpful.

[@turningpoint6643]

Extremely nice work Don. Especially holding your size and straightness tolerance to that level and over that distance, and do so in all 3 dimensions. I'm impressed.

[@SuburbanToolInc]

I am flattered thank you for your comment.

[@RambozoClown]

Great job. Chasing tenths really shows your skills. Nice to see the old Moore and Don still has what it takes.

[@SuburbanToolInc]

Thanks for your kind words.

[@TheDkeever]

I'm in aerospace and we use jig grinding a lot amazing how it works

[@SuburbanToolInc]

It's a great machine, I'm always looking for an opportunity to use it.

[@zach7375]

Don, I absolutely love watching your show. I am 27 years old and I have been a machinist for about nine years now. About a year ago I got a position in our tool room. Along with a few lathes and mills, we have three surface grinders and learning how to master these grinders is my ultimate goal. Your videos help me out. So I just wanted to express my thanks. From the young generation of machinist, to the older wiser one, thanks Don.

[@SuburbanToolInc]

Thank you for taking the time to comment and post it.

[@johncrowley1203]

If you do such beautiful work and still get that much enjoyment from it after doing it for so many years, then you picked the right way to earn your living.

[@SuburbanToolInc]

Thank you its really has been a pleasure that I chose the occupation that I did.

[@nameofdane]

Great seeing that satisfaction with the job. I'd love to work somewhere with projects like this happening.

[@chronokoks]

It's so nice to see an 80 years old man get so happy when the part turns out great. He loves his trade :D

[@SuburbanToolInc]

I certainly do :)

[@dannychavez310]

Always look forward to you and Glenn grinding something. Always nice easy to watch vidioes.

[@SuburbanToolInc]

Thank you for watching.

[@1971thegrinsh]

WOW, I AM NEW TO THIS, AND AM BLOWN AWAY. LOVE IT.

[@SuburbanToolInc]

Thank you keep watching.

[@patrickdarcy3863]

One of the best jig grinding videos I have seen. I worked in powder metal GKN that had some very skilled guys doing profile stuff, they were in a enclosed room for temperature control. This was good thank you. Patrick

[@SuburbanToolInc]

Thanks 👍

[@pauldiaz4273]

Great Job Don!!

[@SuburbanToolInc]

Thank you for watching

[@eddiekvh]

Thanks for showing us a jig grinder. never saw a machine like that before, just heard Tom lipton talking about it. Now I see how amazing it is. wish I live in USA to have access to machines like that.

[@SuburbanToolInc]

Thank you.

[@netovga]

Thank you for share your knowledge.... I use some of your technics here in Brasil. And I love your machines...

[@SuburbanToolInc]

Your welcome.

[@theslimeylimey]

This is why Suburban tools are so damn good. I really want one of your magnetic cylindrical squares for setting up and checking large parts in the mill.

[@SuburbanToolInc]

Thank you.

[@guyward5137]

Always interesting to see how different machines are used in a shop. GW

[@SuburbanToolInc]

It is, isn't it? Especially the jig grinder. Still fascinates me to this day.

[@tomvitagliano4209]

VblockheadDon I love your enthusiasm. Your quest for perfection and your explanations on what you are looking to accomplish has made me a much better armature machinist. Love the field trips. Keep them coming. They educate and enlighten all of us. I appreciate your processing and explanation. It is a pleasure to see someone who truly loves what he does.BravoTom

[@SuburbanToolInc]

Great big thank you.

[@smmarrtzainn]

we were stuck in a problem, how to repair the toggle blocks and platens. you made our day. salute to you sir!

[@SuburbanToolInc]

Glad to have helped!

[@peterblake548]

Don...had you considered performing this operation by setting this part up on a vertical Moore rotary table? They make two resolution tables. One is incremented at 5 sec of arc and the other in incremented at 1 sec of arc. If the total possible angular error would put you out of spec, a true square could be mounted on the rotary table and the 180 degree rotation adjusted by an autocollimator on the table of the jig grinder. Simply pick up the center of the rotary table, dial in to the first hole location, grind the hole, rotate the rotary table 180 degrees and advance the machine to twice the dimension you arrived at earlier. There is no margin for error on these sine plates. In my humble opinion, a 1/2 thousandth error in this hinge alignment will create an unacceptable compound angle error when the table is tilted.

[@panchovilla1486]

Thank you for the wonderful video

[@SuburbanToolInc]

Your welcome

[@cncdavenz]

You still got it Don :-) Thanks for the videos.

[@SuburbanToolInc]

Thank you

[@drumlover1687]

Don from one journeyman to another you are so right. It is not easy working in tenths. The average person has no concept of just how small that unit of measure is. I always like to use the piece of paper analogy and tell them to slice the paper into about 40 equal segments of its original thickness of about .004 and then pick up one segment and theres one ten thousand of an inch. Then they usually say wow I had no idea. In my 36 years as a Journeyman I've always thought this to be a misunderstood trade to the layperson. They don't understand the skill and training this trade requires.

[@SuburbanToolInc]

Right thats a great analogy appreciate your comment, this link might help. kzbin.info/www/bejne/nJfUemN_jNCjas0

[@MrShobar]

Superb video. It also looks like Don is qualified to work in the shop he owns.

[@SuburbanToolInc]

Thank you for taking the time to post your comment appreciate it.

[@karstenschaumaeker7521]

That is the way to achieve high accuracy. Well done brings fun. Do explain see the gain.

[@bcbloc02]

It would have been nice if you had checked the squareness on that plate that was off to determine the problem. That is pretty cool that a machine that is probably nearly as old as Don is still able to be accurate down to the tenths. I guess they are both oldies but goodies. :-)

[@SuburbanToolInc]

Thank you.

[@markv9185]

Not to be critical but To assume the machine is okay, without doing a full range and load analysis, can lead to the other meaning of assume. You where only grinding in a very small work area. I enjoy your videos and the precise tolerances you display. That is why I would expect more detail in determining if a machine is in spec. I watch these to learn the details and if I am looking at this the wrong way, I'd like to learn that too. Thank-you for all the time you put into teaching the world, not only Godliness but the devil in the details too! Cheers

[@SuburbanToolInc]

We did check the machine to the best of our abilities.

[@souhailsaihi1492]

Excellent . Thank you very much for sharing your knowledge. Please Can Do for us helical Gear practise and i would liké to see thé way you Do it. Please start from thé basic. thanks Souhail Saihi

[@ytlechner1596]

Hey Don... what type of stone do you use when cleaning burrs? Any details would be appreciated. Thanks for the great videos!

[@danielwerger5641]

Excellent video Don, thanks very much...!

Thank you.

[@chrisstephens6673]

There is a certain satisfaction in getting things right, the look on your face says it all.

[@SuburbanToolInc]

You got that right.

[@curiousfrankful]

Hi Don;Thank You for your wonderful videos!!!!When I use a telescoping inside snap gauge I try to keep the handle more parallel with the cylinder that I am measuring, then cam it to one side, I see you are using yours at an angle with the cylinder (I can see that the spindle is in the way to use this technique) I have found that even when I use it parallel to the cylinder and that if I'm not careful my measurement will not be repeatable. Are you twisting your gauge in the cylinder? or what is your technique to being consistent? I know that your measurement is right on, because You said so..I just would like to know what your feel is on the gauge so, I can improve my accuracy .Your knowledge is important to me. I thank you for you sharing it with us..

[@SuburbanToolInc]

It is better to have it parallel however it will find the largest diameter you just have to be careful.

[@jeffreylehn8803]

great job!!!!!!!!!

[@SuburbanToolInc]

Thank you

[@christopherdwayne1110]

Very cool. Dwayne NZ.

[@themachinist6554]

I think if your grinding wheel can go through both holes in one fixe then you can go more accurate.

[@SuburbanToolInc]

In theory that's true but the ear is 5" away. They don't make grinding wheel shafts long enough to do that and even if they did, there would be concern for vibration and chatter. Thank you for your thoughts.

[@MrJohn714]

Don you never told us what the part was used for?

[@SuburbanToolInc]

It is the base of a master sine plate. Go to this link intro to Jig grinding at 9:50kzbin.info/www/bejne/omXcf2uoftuJjM0

[@geraldgepes]

How is this typically done in production?

[@SuburbanToolInc]

What you saw is the way we do it one at a time.

[@geraldgepes]

+SuburbanTool Inc nice, no expenses spared. Great job and I hope that your company never changes its uncompromising ways.

[@SuburbanToolInc]

Thank you.

Yes

[@krap101]

Tim Allen is a real person? I thought he was joking...

[@htral]

Hey Don -- You know, they can probably find a few hours a week for you on the shop floor!

[@SuburbanToolInc]

Yeah that is why I sneak out of there as quick as I can to get back to my office.
