Tramming a Milling Machine in 2 axis | Using a Spindle Square 

I had been meaning to buy or make one of these tools for a long time now. I went ahead and pulled the trigger on this one based on your review and it supports small business...I wasn't disappointed. This thing is top shelf. Thanks for putting a spotlight on it.

I'll "second" everything Randy says about the Boring Research gauge! I have one as well. James does a beautiful job making these. Being able to move the indicators is really nice and a big reason to get this unit over the others! :)

Cheers Randy! i had trouble with that setup as i never knew you needed to calibrate it on one fixed point. now i understand. thank you

Hey Randy great video i was always told by my Dad many years ago never monkey with changing head because never get back to square. After watching your video my fear has been removed. Thank you just need to make that same type of tram for my box. Since in Australia usa shipping is same price as the item your purchasing. Thanks again for removing a demon Sincerely Troy Guyette 😊

So many times we try anything and everything to avoid having to move our heads... =) I am long overdue to check my head position even though I haven't intentionally moved it... Great tutorial Randy, Love Grandpa's gauge rod!

Nice one Randy - I bought one a while back based on Keith Rucker’s review. Works as advertised.

Good video of using this Great Spindle Assembly. doesn't matter which way you go, The Gauges won't tell a lie. Therefore consider you set it up correctly and depending on how Meticulous you want to be, you will get a Perfect Table Squareness . Also any other job you want to setup for squareness on the table will always be square with your milling attachment, whether it is just a small flat plate for a job, or even a small cylinder head. Job well done. Keep up the great work.

Nice tool Randy, looks like you got your head all squared again!

Great demonstration of the process. Thanks for sharing.

Looks like you've got your head on straight!! Great job my friend. Always enjoy the videos. See you next time.

Well done, Randy! You definitely had the head out of wack after milling your cement mixer yoke.

Very good Randy. I may have to make one. Well done.

For ever have meant to make a nice tramming rig like yours - ain't happened yet! Tedious process but effective. :)

Head is all squared away again.. nice. Need to check mine soon as well. Cheers, Colin :-)

Good video. I made mine several years ago.

To save time, set the second indicator to zero by loosing the stem screw and move the whole indicator. Now move the head to the zeros on the scales on the machine head. Bring your indicators down to the table and adjust the head till they read the same and your are done...no need to hunt for "zero". I've worked where the head on a Bridgeport type knee mill might have to be moved several times a day. Once you have your indicators zeroed, put the device where it won't get bumped around till you need it again. Then you won't have to bother resetting the indicators the next time you need to use it. Cheers from NC/USA

Ok Randy... I am gonna trust you. I just ordered one.👍

Good afternoon Randy! I like that tool! Going to need to get me one. Mine's home made.

Nice presentation Randy

Nice Unit.

good lesson...enjoyed

Nice, i need to check mine. Its been 6 months probably.

I figured this was coming. See ya tomorrow evening.

I'm a newbe here, an engineer that bought a Bridgeport, just for emergency pieces we need to modify or make. I avoided it for the longest time, and have no plan to eliminate the work we send out, but we need it for last minute. DON'T you want to do this on parallel blocks instead of directly on the table? My table is not horrible, and yes I've stoned it... but there are marks in the table. using blocks would more represent or "span" those Pock marks. Am I right? Wrong?

I always start with a square between the table and the quill. All those indicator rotations when you started that nod adjust are eliminated that way before I even get to the indicators. Just saves some time, is all. Awesome vid, thanks!!!

Randy I had trouble knowing when the Premier was with your back to front date! Remember we live upside down.Downunder

Now if you had a lathe like Brian you wouldn't have needed to do this, 😀😀😀

As a Swedish person I'd like to formally apologise to everyone on behalf of my countrymen for the undersized design of the head tilt and swivel mechanism of Bridgeport machines and all the trouble it has caused through the years😅

This is what everyone dreads. It’s not that hard at all. Also use the ram if you haven’t ! You can set the gib and have another axis while machining. I use the ram as I would the X/Y axis. It has a rack and pinion, it’s sliding on machined and hardened ways. Use it ! With my Mill the ram provides a better more accurate cut than the x axis can. Simply because the previous owners didn’t use it. They would move it to a position and lock it down. Then use the table to make all the cuts. The hardest part for me when tramming in my machine is realizing when tight is tight enough but not too tight or too loose… I Don’t want it to move but if I was to make a miscalculation and crash the tool into the workpiece I’d prefer for the head to move slightly vs breaking stuff. 🤷‍♂️… but I don’t want to do that either really.. so how tight is just right?

Randy, I just got mine in the mail today. I had fairly low expectations but it really is nicely made. It came in a nice foam lined case too, plus a sticker! I don't normally have the luxury of buying US made tools but I treated myself for once. I wouldn't have bothered on my old mill but now that I have a Bridgeport..... Did yours come with the little magnet to do the calibration?

Great video Richard. Can you tell us how you made your way covers?

Great job now it is Randy Richard right.

Well I Don't What The Big Deal Is You Tend To Make Every Thing You Do Look Easy , What Comes To Mind Is The Boring Bar You Recently Made Very Tight Slip Fit Perhaps I'm Easily Impressed Na I Don't Think So

Mine is due as well , the tool i made cuts the time down to 5 to 10 minutes . I Will pop it in an upcoming video . Cheers Randy .

Sust use a square on the table and a drill blank in a collet in the spindle. Or if you are real anal use a drill blank in the spindle and a mag base with a clock on the table. Rotate the spindle to make sure the drill blank is properly in the collet then clock it or use the square fron several positions either side of the table.

I'm two days early!!!

Moving the head is always the last resort on the mill... Tramming the head even though isn't the end of the world, over here, it's considered to be a pain in the b__t... 🥵😰😁

Randy why don't you come trim my mill for me, I don't have them fancy adjusters and I have to shim my nod

Lyle would have it completed in 3 Min with paper stickies & his cup of coffee! JK Nice job & Demo

You had me until you said you didn't need a torque wrench.

But I am afraid... 😁

For a number or reasons your system of tramming has short comings.

Great demo. I bet you could have done this in less than 10 minutes if you weren’t teaching.
