Shop Talk 14: Reamers 

Well said Josh. I even have grandpa’s drawers! And he died in 1969.

Yep, Dad's tools still live in Dad's box. I treat all that stuff like he's still around because in that way he is. Can't tell you how many times I've found what I needed to finish a project in his collection of scrap metal etc. Every time I smile and say "thanks Dad, you're still looking out for me!".

@@animoetprudentia2865 Didn't come here for feels man.

@@MRMIKE276 too bad Sally. You get no apology from me!

@@animoetprudentia2865 I was being sarcastic...

I know they are basic but there are viewers who enjoy them and can help them out.

+vbidou17 I have a floating chuck for the lathes, it's for Morse taper shanks and work great for teaming. I'll have to show that one.

Thank you Adam. I have just found it in SNS 70 !

I wouldn't think there's too much cash left after your barn build.. haha

Money has certainly been going out faster than it comes in!

Isn't that Baily's retirement???

The barn will be Bailys rest home:-)

@@bcbloc02 I thought that was your rest home!

robert hughes You never peck with a reamer. It will screw up the hole every time. In gunsmithing to chamber a rifle barrel, you use a high pressure flushing system to flush the chips ahead of the chambering reamer for this very reason if you are doing precision chambering. Excellent comment.

+Brian Streufert Thanks Brian. I'm always happy to help make your week a little better. 👍🏻

+Scott Tyndall's Home Shop Some of the guys joke about that too cause they don't have enough ass to move a wrench. 😆

The more you know

Hello! Glad your enjoying the videos.

+Garrett Montgomery Thanks Garrett. I do what I can even though I don't have the skills of the fancy Hollywood editing...😁

+Jeffrey Vastine Thanks for the suggestions Jeff. 👍🏻

A solid center point works just as good or better, but you have to keep a hand on the quill handle to use it. I've done it that way countless times for tapping holes.

Good to know. I'd like to test that out sometime.

Ran the reamer in a collet. The quill spring is broke on our manual mill. Ran the reamer at about 500 RPM and let the weight of the quill push the reamer. 500 seems fast, but Carbide tipped reamer in Aluminum. If I remember correctly, that 500 was still well below what Hannibal Carbide recommended. Oh, and the hole was drilled at about 0.612 diameter.

A reamer float helps a reamer follow a previously produced hole.

TheAbsurd Yes reamers are made to machine a hole on size. It's made for a precision fit.

' For a novice '

TODD FINK Yep, good point. I have several that are regrinds and they size was scribed onto the shank.

I got it! I think Adam forgot to mention lube! Dry reaming, ouch!

I completely understand your frustration User Name. I deal with the same types of problems where I work.

I guess the world looks different from the machinists side. It's a good topic for discussion though. What basic items should we keep around all the time.

User Name Same here, we don't have anything.

fortunately we dont have that issue where im at (prototype shop at a multi billion dollar medical device co.), we always have a good stock of stuff, and if we dont have it we can send a req and its there in a few days. ive been on the opposite end though and its frustrating.

Now, what you need to do is submit some kind of 6-sigma opportunity for improvement(or whatever your company's waste-cutting program is). Find a specific instance where a lack of proper tooling has caused someone to blow a big deadline, or for a week, estimate how many hours are lost in your department due to not having spare tooling on-hand. The guys spending the money have probably never been in a shop, much less worked in one. They don't understand that tools are consumables. It's annoying, but you need to tell them in a language they understand. And my goodness, they love numbers and 6-sigma initiatives, but hate lost time or missed deadlines. Ex: If a shop of 10 guys average spending an hour a week replacing or waiting on tooling, that's 500 man-hours a year lost. And your pay rate is not your cost per hour; if you make $20/hr, your effective cost will be something like $50/hr. So, on average, if each guy spends an hour per week, or one guy a week sits there for a day while a part is over-nighted actually will cost your company something like $25k/year. And if a deadline was missed, that can be tied to thousands per day. Put it in terms of cost, and the accountants and budgetting managers will listen.

+Eli Douek I have wanted to do a refurbish/rebuild on my little surface grinder.
