Here is how our grates get drilled at the factory. It is an old Bridgeport CNC Mill. It originally had Boss 5 controls I gutted it and upgraded the controls and drives.
These grates used to be drilled by hand on a drill press. 130 holes for the 90K grate and 182 holes on the 110 grate.[/quote]

OMG...aren't those stainless steel too :cry: you must snap drill bits left and right :lol:

No they are just grey iron. Not to bad about 28 of the 182 hole grates / bit . ! grate about every 10mins

MAN! I would love to have a drill bit do half of what that one is doing! Would take me half an hour & lots of swearing to drill ONE hole through that ...

I can never find decent drill bits that last. :mad:

I always found that sharpening up your own quality USA steel bits is by far the best! Just like the best chain saw sucks with a dull chain... dull bits make life miserable too. back in my days as a welder i would keep a 5inch grinder next to me though for small bits a wheel grinder is best. the minute you feel the bit dulling just give it a quick hit (oil the bit while drilling helps too).

BOSS 5 ! Wow, I remember those, my 1st time was on 3 series...crazy old school punch tape machines. Oooo, then they made milar tape that wouldn't rip all the time LOL!

http://www.mscdirect.com/ or http://www.mcmaster.com/#r will offer the best that the non-industry folks would never know about. Go straight to the Cobalt section for tough materials and HSS good quality Drills ( nitride coating is helpful) for every day mild steel ( 1018- a-36 - cast iron-etc. ) remember Lower RPM with strong down feed will yield better tool life and efficiency over high RPM's which most non coolant fed applications will end up with burnt out drills and work hardened material.

I tried a lot of different bits. The ones we are using work the best. I will let you know tomorrow the brand. Of course made in USA.

I agree! It's a lost art though! If you ask most people if they can sharpen drill bits they will say no. It was one of the first things I learned as a machinist in the Airforce . I sharpen brand new bits because I feel like they are shaper when I sharpen them than they are new! In fact I really pride myself In sharpening bits :) I am stilling usin the same set of bits that I use for stainless . I usually never have to buy drill bits.

Great quality stuff here... I bought my drill press from the ole' Foxboro Company and it still works great 20 years later! better then any of that China made "woodworkers warehouse" junk they sell today :lol: Ill post photo after my Camera is charged ;)

May I ask how much you got that beautiful Bridgeport for? (idk if its a Bridgeport, I just call all machines that do that stuff "Bridgeports" :lol:



There is a Bridgeport to the right of my machine and it sold for $1200 waiting for pick up. I wasn't intending to buy anything last Saturday . I told the guy I didn't have any money. The Cincinnati was the largest and he had a price of $2400 on it but he said he would sell it to me for $750 if I signed a deal with him that day right then! I didn't have to think long!

It is a Cincinnati tool master knee mill and shaper . The shaper being on the other side of the turret.

They say some days the owner has high prices and some days he makes incredible deals. Either way I told him he just won my business for the rest of my machinery.

I know its not a "Mill" but for me i would'nt ever get rid of this "Beast" (the chuck has a grip like iron and the drill is so powerful it will take my right arm off at the socket if it ever jambs... just the way i expect a good drill press to run! :lol:). I dont use it often but its a great lil' unit that takes up very space and when I need it I know its their for me and I know it will drill anything like "butta" :clap:

P.S. excuse the shop pig pen, ill clean as soon as it warms up and i can have my epic yard sale :P


That's a really nice press ! I just saw someone posting a photo of this earlier today on one of those photography web sites! Vintage machinery is so great!

I need to post photos of the power cross feed. It has a huge motor on it! This machine was made in the 50's . Do most modern servos have multiple speeds? This power cross feed has 9 speed settings. I want to say I remember the little servos on the kondia I used to use only had one speed maybe two.

I just got a southbend model A catalog number 644Z In my garage last night. I need I put it all together . I have gearing to do metric threading as well. It has a quick change tail stock set up as well I believe .

I am building a base for it out of a section of beam this week.
It is a war production machine.

350lbs anvil made in kohlswa Sweden followed me home.

this little propane forge from NC tool followed me home as well ;) .

I miss doing this kind of work! Pretty much you can make any old mill into CNC with servos I believe!

Well.... I think yes & no. Backlash is OK in a manual mill because you always "take it up by hand" on each pass. With any CNC backlash slop is a killer. If you cut a CNC'd circle with a mill that has backlash you end up with a four lumpy sided circle. Yes, you can ask the software to compensate, and some softwares do an OK job, but, for excellent accuracy you need quality ball screws with anti-backlash or double ball-nuts. To put ball screws in an existing machine can be limited by budget or by physical room. Ball nuts are much larger than a stock acme thread brass nut. Good ball screws are not cheap!

OMG...I did the same thing when opening new bits the first thing i'd do is put my own taper on them and reduce the angle of the cutting edge (better then brand new and cut like a hot knife through butter) :P Thats funny to learn someone else did the same tricks I did when i was a kid (drill manufacturers must not have tested their bits to much or you think they would have realized what worked best :mad: )
