So many people focus on the task of scraping, and not how you to check the geometry of the machine, and the progress of the work, which is the most critical part of scraping. You did an excellent job of emphasizing that. I've been scraping for over 40 years, and teaching machine tool alignment and fit (scraping) for the last ten. I must say, your methods are unique, but quite effective. Keep up the good work.
Thank you so much for making a video showing your measurement process. I've begun my own journey on rebuilding a Bridgeport clone, and it's really helpful to see someone else's thought process. I haven't watced part 2, yet, but I think your initial measurement of the knee squareness was problematic. If the face of the granite square was not perfectly parallel to the face of the way, any sideways movement way would change the reading even if the knee was perfectly square. That said, the measurement with the knee on the column is the ground truth.
I was wondering about that as well. Perhaps pushing the square up against some gauge pins would have solved that issue? But I'm still not understanding how you make sure the dovetails are perpendicular to the column. In any case it's a fantastic video.
Nice job! The Gibs and interior dovetail surfaces were maybe a small waste of time, since they're just a variable adjustment tool. As long as you have as much adjustment as you need with the adjusting screw, there's really no need to do anything.
Nice work. Do you think when the machine was designed the knee was purposely out of square a tenth or two? To compensate for gravity taking up all the gib clearance and causing a tilt in one direction?
Hi Vince, my name is Valmir, could you answer me if you can provide me with the design of the parts for CNC assembly, as I'm waiting for your reply that I sent earlier in the cnc milling machine assembly video
One thousandth of an inch = one "thou", one ten-thousandth of an inch = one tenth Even the abbreviations in the imperial systems are aggravating. I work in both, and it drives me up a wall sometimes.

good job.
After scraping how to hard coat slides plz guide.
Thanks for a well paced and presented video. Really useful information on how you approached measuring and maintaining the correct geometry
Awesome. I have an FTV 4 I am rebuilding! I can tell by your technique you were R. King trained....
Very nice work.
Impressive to say the least.
Thanks for sharing.
Take care, EM.
That R&M bit is genius.
It is interesting how were made first machine tools when there were no machine tools?
It is an interesting question to discuss
Indeed, and never realize these first machine tools builds better machine tools.
good rebuilt..thanks for your time
Thanks for a great video👍
12:31 - Great explanation on the topic. How did you get the BP to be on it's side like that? Scraping the gibs is the most difficult part in rebuild.

Glad you found this helpful, I had lot of fun doing it and end result is very satisfying. Word of advice, don’t rush.

What spotting die are you using, the contrast look very good !
Most likely "Dykem" it's what all machinist use for rebuild.
Hey there what is the tool used to mark ways with blue color?
Kitchen floor came out better than the knee, hmmm, good job on the floor, the knee ahhhh
Very cool! Why didn’t you use the 45° angle on your camelback to check the dovetails of the column?

I have heard better contact with the gib helps improve vibration and rigidity
Love the level holder, going to make one this week! What dia round bar did you use?
Hi.Dou You have manual with parts list for this mill head?
Nice work. Do you think when the machine was designed the knee was purposely out of square a tenth or two? To compensate for gravity taking up all the gib clearance and causing a tilt in one direction?
Normally they are but mine is off when I measure it from side
Well Done!
waiting for part 2 :)
Well done sir

Hello I do not understand what is a "tou"or a "ten" I live in metric system nice video
.001” = .0254mm .0001”= .00254mm
@@advanceair One "though" as "one thousandth of an inch"
One thousandth of an inch = one "thou", one ten-thousandth of an inch = one tenth
Even the abbreviations in the imperial systems are aggravating. I work in both, and it drives me up a wall sometimes.
very nice :D:D
Change hobby.is no possible stop the gib like that for scraping.also for check a flatness of slidways need a level,better the square level...
My kitchen floor is one thenth 🤣
Nearly end was no very nice measurement.for do it need a square level ,and u can check that before,when you scraping
