One doesn't ............. that's why God invented the milling machine  ::)



David D does  :poke:

Lazy git... :lol:

That's why I'm making some.... :nrocks:


The best fitting nuts are individually made, to fit.......  :wave:

The recently bought nuts need 1mm off the wider section, to make `em fit the r/ table.  :thumbup:

The 4 nuts which came with the mill, for the mill table, are much too loose in my opinion.....

AND, I`ve still not finished those oversize nuts I found in my toolboxes.......  ::)

I really do not want that sinking feeling, as a piece of machine table breaks away!  :bang:

That was kinda my thoughts as I was looking through the adds for these things...... :scratch:

Making your own as you did is the way to go.  I needed two t-nuts for a rotary table, and decided to mill some material off of some that were in my clamping set.  These were hardened and ruined an endmill.

This may seem obvious but here's a little tip. If you have material and you don't know if it's hard or not, use a file. If it slides over the metal with out cutting it is usally hard. If the files cuts then it can be considered soft. Then at least you'll know if you need to use a carbide end mill or if that HSS will do.

This morning, I milled off .5mm from each side of the 6mm nuts.

I used a tired 10mm carbide endmill & deburred with a file...... No problem!  :thumbup:

Good on you David, did someone prompt you to do something about them  :poke:  :ddb: :ddb: :ddb:

I'm quite pleased with the milling finish I'm getting , just done one side here...

Yes, someone did!  :wave:

Also, after several days enforced layoff, the weather/ arthritis problems have eased a little today!  ::)

I know it's only T-nuts and I could get away with something much less presentable,

I'm just practicing various methods of milling and finishing,

So don't be thinking I'm a very sad and lonely individual...... :lol:

Nearly finished all the blanks I need, just need to take a smigen off the last one.... :ddb:

They take some making these things, I hadn't realised how much time the milling would take..... :bugeye:


So if anyone says they buy theirs, I won't  :poke: fun, honest....

Believe that and you'll believe anything  :lol: :lol: :lol:

Darren,

You are now going thru the natural progression stage of machining.

You know you can now make the parts to an acceptable level, so you are refining your techniques to produce a more cosmetically acceptable piece.

Roughing and finishing cuts are very acceptable methods of making a part.

There is only one way to go after that, hand finishing and BLING.

That's the one, change spindle speed, feed rate, depth of cut, listen to the machine, watch it jump around on the table...ooops  :lol:

Getting the "feel" I believe it's called... :)

Finishing is easy, belt sander takes care of that, done in a flash.

After that it's polishing, done a fair bit of that in my time.... :ddb:

It's the actual machining that that I'm behind on, getting there, slowly.... :nrocks:

Someone commented on machines always looking too clean in their pictures,
Mine gets dirty too  :)



A couple have also commented on the finish I get. In this pic you can see the milled finish and the "other" smoother finish. There is nothing wrong with the milled results, it's very smooth. I'm just playing as I said before.



And this is what I use to do this. A bench top belt sander, it's fast and as you can see leaves a nice finish. I'm currently using a very coarse grit on these t-nuts 80grit.
120 grit leaves a much better finish but not needed here. I use this machine a lot and the belt lasts a long time. I think this one has been on for over six months and it's still going strong.



I've got a bigger floor mounted belt sander in storage that I've yet to use, be interesting to see how that gets on?

You might have stunning engines, but I have the best looking T-nuts around here... :)


Drilled and power tapped on the mill....



Cut to size and pinged the end of the threads over



Job done, all my tooling now has proper fitting T-nuts, well ready made strips at least, the others can wait till needed before drilling and taping cos I've had enough for now... :med:

Now to stick em in the mill and ruin em  :lol:

Erm.... Am I a little late to this thread?  :coffee:    ::)


Nice work there chief :thumbup:  I have that "need to make 'em look nice"  thing a lot of the time, sometimes I can do with the "it's functional" but most of the time I have to flash it up!!  :ddb:


I'm glad the unknown steel works well  :thumbup:  It's well seasoned and generally bloody strong  :thumbup:


Nice cuttting without hands on and a cramp in your thumb!   :clap:

I''ve got 6 new lengths in the van this week  :beer: told you there's plenty of it to be had  :headbang:




Last time I made T nuts I made them for my RT (small with a M6 thread) Still got a 5" bar left in the right shape. It'll come in useful one day  :thumbup:




Oh oh.... The jokes just get worse!!  :lol:
