Home Shop Made Tools

[PixMan]

I'm just so grateful and humbled by all of Rob Wilson's project, posts and especially....the PHOTOS!

I don't know when I've ever seen such great lighting, composition, tonal scale, sharpness and overall look in product photos. We're awfully lucky to have you posting this "tool porn" here Rob, thank you.

I'm glad I'm not the only one that thinks his posts are truly tool porn of the highest caliper. His posts spur me on to do better. I've got a lot to learn and his posts show me what's possible in a home shop.

Maybe in others but certainly not in MY shop.  

But I'm still happy with doing what I can.

Geez Rob, your stuff just blows me away. I'm not sure whether to be inspired by what is possible, or to give up now because I can't see myself ever putting out anything that good. I'll try and lean toward the first of those options.

About the fly cutter, the guy in the videos who makes the tool that this is based on (and I really like his videos) makes much of the angle at which the tool presents the insert to the work. I notice in Rob's tool, the insert appears to be presented at 90 degrees to the work; is the necessary geometry incorporated into the insert itself?

After I first saw their fly cutter, I had thoughts of making a holder to use one of my lathe insert holders as a fly cutter. Does that sound like a viable option?

I would think that it depends on which type of insert that you are wanting to use,

A positive rake insert already has the rake angle in the insert, but for a stronger insert edge you would want to use a negative insert which you were to make the insert holder you would have to cut the angle on the holder.


Just my take on it.

My only issue with any of the fly-cutters which use carbide inserts is that of the inserts themselves. Since TNMG inserts were developed for turning, the bulk of the grades available are harder and intended for continuous turning operations.

Of course today's carbide is far better and stronger than when TNMG's were first available, so perhaps a moot point. You can get some very upsharp geometry in that shape insert now. Look for TNMP or TNGP and they'll have a very positive chipbreaker. In grades, most makers now include data which will state the relative toughness versus hardness (and wear resistance) of the grade. For the interrupted cut of fly cutting, look for values such as P30/M30 or higher numbers, rather than P10/M20 type of numbers. Both will work in finish cuts, though the tougher grades will sustain even slamming into flame cut crappy steel.

^^^Agreed!

My ONLY problem with Rob's pictures is that when I see his work and then mine, I have second thoughts about posting some of mine.

Hi there Pete , 

Thats correct , the TCT is mounted at 90 ,and they are for a lathe tool . the reason being I have about 10 boxes of this tip , being a hobby shop we/I use whats available , no point making a tool I would have to buy tips for . Yes you could go to a far end of a fart to get that 10 seconds off the time it takes to machine a part with the ideal tool for the job ,but this is just a hobby for me so if it takes 1 hour longer I am not that arsed . What I am trying to say is make the best of what you have at your disposal.  

The results speak for them selves , and I have used a grand total of 2 TCT since I made the fly cutter .

These are for my bench vice jaws , 4140 or there about's .





And to answer your other question about using a lathe tool ,,,,,,,,,,,,,,HELL YES 

Here you go , one of those cheep flycutters  , you know the ones ,come in a set of three (really handy around the shop ) and a 1/4 LH TCT lathe tool . 




Thats the cutter bar for the larger fly cutter . Even a bench top mill will get a finish on a part like that. 


I would like to end by saying thank you to the lads for all the kind comments on my work . much appreciated .


Cheers Rob

Rob,
Nice post, they say a picture is worth a 1000 words but your written words of wisdom are worth a 1000 pictures.
