Dear Dr. Dinglefarb, I really enjoyed your 3rd installment on the Autometric's motor mount. You withdrew a few solid laughs from me that were bigger than the "Aluminum Wig" the Hougen Rotabroach was wearing and swinging around like Jon Belushi with his Toga on! LOL! Thank you for that laughter, and also for just being so mellow and not taking things so seriously you can't laugh at yourself. I definitely try to surround myself with people like that, life is too short to spend your time any other way. Your ad-lib vocabulary was classic in this show as I've come to expect and enjoy. It reminds me of how we used to talk at the bodyshop while working on all kinds of cars with all races of people. Made up words and modifyers made communicating faster and just more fun! Hoping you're having a good week, Aloha...Chuck

Very cool! Thanks for sharing your time and talents. All the best Chuck.

Thank you Tom for the nice project work. Enjoyed watching with the morning coffee. Randy

I like the hand interpolation method! To avoid that interrupted cut, I have taken a deeper doc in the past. Thanks for the great video!

Gday again Tom, I liked your freehand milling work mate, I've done a bit myself & it is not as easy as it looks, it takes a lot of practice. Freehanding radii on a lathe is something that takes a lot of practice also. Good stuff !! Cheers, Pete. aka - "Pedro"

Hey Pedro, I did a few in the lathe back in the day. Used to match them to templates for non precision stuff. You can also step turn large radii with great results. Cheers, Tom

I always set the vice up way to one side of the table. That leaves you a nice size area of table for non vice work. I do this on the CNCs too and rarely have to move the vice. We have a bucket full of 1" thick aluminum slugs from the waterjet that are great for blocking up stuff on the table and it hurts nothing to cut into them. Its nice to have lots of space under the work for chips.

Thanks for showing the manual interpolation technique. I wish I had seen this a couple of months ago when I needed to bore a ~4" hole... Instead I started with a 1 inch drill and then bored my way out one pass at a time :) Thank goodness for the power feed on my mill

Hey Hans, We used to do a lot of large holes in thinner material. If you practice a bit you can actually get pretty close to the line. Cheers, Tom

When you cut through the hole with the annular cutter I recommend letting the spindle head come to a stop before raising out of the hole. You don't want that sharp-edged plug spinning out of the cutter in your direction. Sometime those plugs are loose and can drop out of the tool just by gravity.

that is so cool the way your doing that :) thanks for sharing

there is a really nice MQL set up by Uni Mist which really does not flood out the cutter path.. use one on the presses too.

I like that, your BNC cutting . (B for brain).Even the chip blower is human powered! just like on the big handwheel.

Don't know why, but I really enjoyed watching the large rough hole gradually become perfectly smooth. "Lady Luck" credit: LOL. Jon

Tom, watching that Rotabroach spin in and whip up that cloud of stringy bahstahd chips made me think of Taz from the cartoons when I was a kid. Needed that turbine spin up sound effect to go with it though! Nice job interpolating. You can be the standby in case the CNC controller goes toes up. Thanks for letting us watch! -- Mike

Hey Tom, you sure get excited when you whip out the "roto-broaches". ...happy to put them to use. We/I used a similar kind of hole cutter at McDonnell-Douglas (to cut holes for circular "Cannon" plugs). Gota dig the thick wall. They cut super smoothly.

I like how you left 5 thou for a finish pass on that first bore. Better lucky than good eh? That was close. Cheers, Gary

Hey Brian, Its called slap bang. The only good thing about an interrupted cut is the chips break without trying. Cheers, Tom

Tom I noticed when you were roughing out the large hole that when you stopped moving that the cutter squeaked. Whenever I am pocketing out something and getting close to dimension I have the same problem because I need to feed slow or stop to change direction. Other than not stopping or slowing down is there something that can be done to help this as I find it often leaves tool marks?

@oxtoolco

10 жыл бұрын

Hey Bill, I never worry about noise when roughing stuff. If you increase the chip load either by feeding harder or slowing the spindle with the same feed it generally goes away. If you just cannot have any marks you have to go really slow spindle speed or step down the depth incrementally. Even that is not a perfect solution. Cheers, Tom

whats a collet ? 😅

Can you make a single tooth toolbit for the boring head? Like a hole saw or annular cutter but with one tooth and cuts to an infinfinite range between the boring heads limits. Nice mount, coming together nicely. Really liking this series of fixing the jig bore.

Tom, Another great video. A couple of questions. What were you spray on the 1/2" 2 flute mill. (WD-40?) Could you use the boring head to cut the annulus matching the scribed line? Eric

@oxtoolco

10 жыл бұрын

Hi Eric, Yes it was WD-40. You can use a boring head to cut a annulus through a part as well. The official name for that is Trepanning. The width of the groove makes it a sometimes tricky operation. Its really simple when there is a large space radially from the slug to the wall. When that groove is narrow with a single point rotating tool it can get exciting. Cheers, Tom

When you were making that preliminary cut on the large hole, the technique is much the same as drawing a picture on an Etch-A-Sketch toy....maybe coin that method as such?

Tom, I know why you use canned air, to save money, do you refill them, using a tubeless tire valve? Also great to recharge cans of paint and other products.

Hi Tom, I like the "lazy trick", hope you're lazy enough to show one of those per video... Good work, thanks, Pierre

Note to self: zero the dials before etchasketching out the plug ala bore 2 - I can just see myself seeing that center punch mark falling away and kicking myself before it hit the bed :)
