I saw a boring bar holder on pg 105

I think this is the old Armstrong unit can anyone post on how it is made.
thanks Pat

It looks like my "Williams". It's a turret design that takes 3/8", 1/2" & 3/4" boring bars.

I've seen them made two different ways. One is just two halves, top and bottom, with the different sized holes criss-crossing. The other way is with a center pillar with the largest size hole bored through it. Then there's the outer sleeve that is made like the first way, just that it's hollow to accommodate center pillar. Either way, stick the boring bar in the hole that fits it and go.

That's mine! I got it at the flea market.

I'll try to pull it apart and grab a pic in the next few days. It's dead simple.

Edit: I was planning to start a new thread and reference P.A.R. in the title, since it's not shop-made.

click on the photo for a short video of the shaper operating.
Here's my home made shaper I made the patterns, cast the aluminum and machined the cast parts. Took me about 3 months start to finish.
I used the Dave Gingery plans. I've also built the metal mill and dividing head from the Gingery plans. I found it fun to do.

My first post "Houdy" to all you guys!

Great job Norm! That's a very good time line you ran there if you did it part-time.

I worked on the shaper daily until it was done. I did take off for week ends and for a couple of weeks. I really wanted a shaper so I could build the mill easier. Using the shaper to machine the mills parts made it a ton easier.
My whole reason to build these machines was so I could make gears to repair my old lathe. the gears I needed for the lathe I couldn't find or buy.
So I did finally get all the machines built and the lathe repaired, about the time I got the lathe repaired my son bought me a new G0602 Grizzly lathe. So now I'm looking to find a bigger mill or a new Grizzly mill. I'm looking at the G3102 mill I may have to come out of retirement to get it. Why do I need a mill? I just want one to make things with.
I added reverse tumbler gears to the G0602 lathe and a speed reducer slowing the lathe down to 40 rpms for threading. All the parts were made right here at home to do the changes. I have quite a few post about all this on "projects in metal" forum. The plans for the reverse tumbler gears for the G0602 lathe can be found there they are free so if anyone has a G0602 lathe and wants to add the reverse you can do it pretty easily. The reverse gears set up could be modified to work on most China lathes I think.

Whether building your own or completely stripping and rebuilding an old machine, there is nothing like it to really get to know precisely how the machine works. Highly recommended for anyone who hasn't ever owned or thoroughly used a machine of the type.

I have went through all 133 pages of the postings and there is a wealth of information here. Some of the items are flat incredible and kudos to their makers. Mine is much more modest though I find it quite handy.

The only thing modest here is you.
You're incredibly resourceful. Field expedience at its best!

Thank you Chris

Thanks for the thumbs up. Comments like that always feels nice.

While not exactly a tool, more of an enhancement to a tool (my little bulldozer), the following 2 pictures are of a center pivot I am fabricating for the dozer blade. I intend to make angle adjustments of the dozer blade possible while I stay in the seat when I have to plow snow this winter.

The material is a 12" length of 3.5" OD schedule 40 pipe and a 14" chunk of 3" outside diameter tubing. I had to take ~.060" off of the 3" tubing and clean up the inside of the 3.5" pipe to get things to fit together. I need to split the plates and weld on the clamp devices so I can secure the pipe and tubing in their respective plates.

It is probably a little difficult to picture how this will all work but the left hand plates in the top picture bolt onto the top and bottom of a 12" wide x 30" long piece of channel iron that the bulldozer blade is currently attached to by 1" od pins. The plates on the right side will be attached to the dozer blade itself. I need to attach all of this onto the little bulldozer tractor so I can determine the lengths of the toggle links on each side. A smart man would have modeled this with a 3D software package in virtual reality but I decided I would 3D model it in physical reality

I will post more pictures when I get it mounted on the tractor.

Ironnut, that looks like a stout hinge for you blade, I'll have to think about that when I do mine! What kind of small dozer do you have, I have a Magnatrac!

[ironnut]

50s vintage OC-3

My little dozer is a 1950s vintage Oliver Cletrac. It is about 20+ plus horsepower and weighs about 4000lbs. I refer to it as "little" as compared to a D-2 or D-4 Cat it is pretty small. Its primary purpose is to plow snow in the winter although I built ripper bars for it and we it used to loosen our horrible soil when we were digging the basement of our house. I will post a picture of it later.

My dad and I recently got a PM 14/40 lathe and 949 mill. The last time I ran a lathe was in high school, 20 years ago, and the only milling since then has been very limited stuff on an Atlas tabletop model over the past couple years. Just getting the machines to do anything is wonderful and fun for us.

We were trying to square the head on the mill recently and was pretty sure the dial was getting knocked out of position when it hit the T slots on the table. Then I remembered having this bushing from a Manitowoc crane laying in the scrap pile. A couple hours of turning on the lathe (which was great experience for dad who'd never run one in his life!) and we have this, which I hope will get us going in the right direction.



Since getting this far we haven't had time to get back on to squaring the head. I told dad we may shorten it so it's not as high, and also finish boring the center to completely clean it up.

Outer ring from a big ball or roller bearing works pretty well too.

[Mcgyver]

Totally agree, Rob has done some really great stuff and posted it on that forum. The work is a credit to him.

Dave

that was a well done project. I don't remember to stop by this thread as often as I should - fantastic work you guys. At 1400 posts I think a lot of the guys might not be looking here anymore and these projects aren't getting the attention they deserve. Norm that shaper looks great and is a king sized project and would get pages of kudos otherwise!
