Hi All, I recently squired a Brown & Sharper Micromaster 510 that seem to have most of the guard in place to run flood coolant but it is missing the coolant tank and pump. I feel that I need to at least try flood coolant. One option would be those tank and pump on ebay...

Today I had the chance to play a bit with the grinder. The first task was grinding the chuck That first attempt was pretty bad but the second one was a bit better: I then play around with correcting some AliExpress ER32 collect block. I am pretty happy with the surface finish I am getting...

I used this bearing vibration calculator for 6203 bearing and there is no match for the 190hz. Brandenberger message inspired me to simply reinstall the motor and see if this is good enough. Wow, the difference is incredible ! I can barely feel any vibration on the wheel guard now ! I moved my...

Phase Perfect

I will definitively take the time to read this, it sound really interesting ! So I went ahead and drilled some holes in the pulley to try to balance it. I knew the unbalance would be mostly cause by the keyway so I went with a simple 3 holes at 120 design. It look pretty ugly because I don't...

I finally had time to make more progress: The motor was re-assembled with some new bearing, it now sound way better Here is the vibration without the pulley And with the pulley I am quite concern by this 190hz peak, which actually have a value over 180. If someone have any insight as to...

This is awesome! What are those sensor you are using ?

Hi Conrad, Yes, I saw your page, this was my main inspiration on how to balance the wheel. Thank you for this amazing write up ! My plan to balance the motor is to balance it with the pulley installed as a single unit. I would really like to do a 2-plane balance job but I don't really have the...

I went ahead and remove the motor. Running it by itself, I was not happy the amount of vibration coming out of it and the noise it was making. At first, I thought it might just be all the gunk in the fan, but removing the fan did not change anything. I now have the motor fully apart and...

It is hard to say exactly how fast I am running the table. The best I can say is: about what seem average from the youtube videos I watched. I have a old linear scale laying around somewhere, I might try to hook it up the the setup later on to see if I can measure the speed.

Hi all, I recently got my hand on my first surface grinder, a Brown & Sharp 510. After doing some initial testing, I was really unhappy with the surface finish I was getting: I am getting a lot of "wave" in line with the Y axis. After reading a lot on around the internet and on this post, I...

I have a Wohlhaupter UPA3 Mo.4xS20x2 boring head which I think might fit a Deckel. Located in Ottawa, Ontario, Canada, will ship internationally if paid via paypal. 850$ + shipping

Here is a couple of picture and dimension of the "bracket ?" Full album here: Graziano Sag12 Taper Attachment - Google Photos I would really appreciate if you could send pictures of the screw. Thank you

I am looking for some picture or dimensions of the original "screw" part that goes between and the slide and the "way clamp" on the Sag 12 taper attachment. It is missing on mine and I want to make a new one as close as the original as possible. Thank you

Hi, I might have the opportunity to get my hand on an Moore #3 jig grinder but I want to know if I can fit it under my 8 foot ceiling. I am 95% sure that the hose are more than 8' and I am ok with cutting part of the ceiling for those but my main concern is would it fit through the garage door...

You can use a right hand drill bit but you need to flip you mill upside down. 2.5amps is the theorical limit rpm of your motor, just plug you servo directly in your wall power outlet. If you are in the us, that is 115v so 115000 rpm. You should be able to do all your holes in less than a minute...

Hi Cody, Shars have very good price, but I am in Canada and the shipping cost are simply crazy. There is a mitutoyo 24x36x5 that have been for sale for 3 month at 1h30 hour from my house. I will call him to see if he would accept a very low price. That a nice test bar you have there, DIN2080...

Hi Ross, Thanks for all those invaluable information ! I really like your idea, it is a fix that will take more time than money, and this is my kind of fix ! I will probably just fix the spindle for now, get a little bit of experience with the head out of tram, and then repair it later (it will...

Hi Ross and the others I finally remove the head and did some crude measurement on the table. I am a a little bit limited with tooling but I do what I can with what I have. So what I end up doing is putting a piece of paper under the surface where the crack end. I could actually pull the paper...

Definitely ! I just did a very quick test and just sliding the head against the ram and tightening the top bolt by hand. I could not see the smallest space between the 2 surface, and there is no way I could fit a sheet of paper between the two. I will still try to remove the head if I have the...
