The pins look good Rob, Like Peter says you may aswell do a batch next time

, That little vice looks interesting and a handy bit of kit

I bet there will be hundreds of your 'Patented' vice jaws about in a few weeks lol

................... you wont get no money................ but you might go to heaven

Cheers Mick.

Rob,
You can't use those works of art on that poxy old vice, you will have to completely restore it and polish it all over.

Cheers David

Another brill idea with the pins Rob, but please dont come up with any more jobs to do.

You know I'm right

One of these days I'm gonna make something worth showing off about.... But it ain't gonna be a super clock! Far too advanced

When I get a few days I'm certainly gonna make up some vice jaws.... My aluminium ones are getting very tired.

Don't got none of that super chrome steel that they have up north, so they'll probably be made from old garage door bits

Not too sure about hardened ones.... But the beauty of owning these machines.... you can always make more

Well Rob, it's a bit pointless to design and build something like those jaws and not know for sure that it's an interchangeable parts fit. I just happen to own another 5" Record I bought before they closed up shop maybe 15? years ago. With some proper arm twisting and maybe a keg of the British finest shipped over, I just might be willing to test those new jaws on my vise for you. Honestly there's no real thanks nessisary. I'd just feel guilty if you tried. If they do fit? Well then you'll know it's a good accurate design and you can then build another set for your vise.

Cheers lads

I knocked up the shouldered screws this morning

hopefully I will get time this weekend to hardened all the parts .

Looks like another one just about off the list. Excellent workmanship as usual. Thanks for sharing with us.

Cheers

Rob.Wilson · « **Reply #35 on:** February 17, 2013, 04:37:47 AM »

Thanks Don

Well there not looking so good now

hardened

And I have a wee problem with two of them

, the buggers cracked ,BADLY

Those two I just left in the pickle over night that why the surface looks so ruff /corroded , I will dig out my crack test sprays and see if the others have any fine cracks I cant see with the old eyes . Either way I will be milling up a few new jaws

Rob

loply · « **Reply #36 on:** February 17, 2013, 05:34:12 AM »

Rob,

That's very frustrating. The crack along the face looks odd as it doesn't seem to stem from anywhere in particular.

What material are they made from? Were you case hardening or through hardening?

Could you possibly stop-drill, tig weld a nice deep puddle, and regrind to hide the weld?

Rich

Rob.Wilson · « **Reply #37 on:** February 17, 2013, 05:52:23 AM »

Hi Rich

Frustrating , sort of ,it happens , I am sure I will learn something form it

Quote

What material are they made from?

Wish I new , did the usual scratch and sniff test (spark test) can up high carbon , did sample pieces with saw cuts/vee's machined in ,carried out a brine,water and oil quench all came out fine .Probably next time go for the softer quench ,oil instead of water .

Quote

went for through hardening.

Odd that just two cracked , the one with the crack on the face stems from the bottom of the pin holes

Quote

Rather just make a new set

Nice work Rob (there really should be a dedicated "nice work Rob" smiley).

What about case hardening the jaws?

micktoon · « **Reply #39 on:** February 17, 2013, 03:59:18 PM »

Hi Rob , sorry to see them cracks like that

..........the only silver lining ( if there is one ) is you will probably figure out what caused it and be able to avoid happening in future projects that you might have spent more time on. Oh if your making full new sets ...........dont go throwing anything in the bin ............ I know someone that might try practicing T.I.G welding on parts something like that

Cheers Mick

A true craftsman to do work that well, and take it in stride when a step didn't turn out, and make it again, better even than before, And showing the problems so we can all learn.

jb3cx · « **Reply #41 on:** February 18, 2013, 01:49:59 PM »

That's a bummer rob all that hard graft down the pan. Never mind rob I'm sure you will get it right next time

Hi Mayhem

Case hardening would be one option , BUT they would need to be pack hardened/box to get a good depth of case to allow for any distortion to be removed by surface grinding , I would have gone that rout if they hard fit in my case hardening box , 1/2 inch too long

Hi Vtsteam ,,,,,,, Some days things dont go to plan ,would of if I new exactly what I was trying to harden

, either way it has give me a chance to change a few things in the new jaws

Cheers Mick

are you sure Mick ,,,,,, did a bit destructive testing , took a sledge hammer and an anvil to bust

Hi Peter ,,,, It happens

Well my plans went out the window, wile cracking on with making a new set of jaws,minding my own business I here the thud thud thud of an old motor cycle put up ,my mate on his Norton ,in he comes jibbering on about Stafford show ,centre circle and needing his Triton built in six weeks ,so I have now been roped into helping out

Then mentioned do I want a Beaver mill for nowt . went and had a look.

Just a tad too large for my needs

so it ended up skipped , but I did whip the slotting head off, may come in handy

and wile rummaging around the scrap I stumbled across a Elliot vice , bit rusty , but not drilled another one to add to my collection of vice's that need attention .

Back to the jaws ,I managed to get a set of blanks machined up .

Hardened the plain jaws , oil quenched this time .

and ground up.

Dont no if its just me but they seam to have a better grip for less tightening of the vice .

And holding thin parts edge on at the tip of the jaw is a breeze , ruler is 0.4mm thick

Rob

Cracking job as usuall
That mill would have been very canny for your "collection"

Well come on Rob - this isn't like you

Would have expected you to immediately set to work and made a bigger & better one !

Is pragmatism creeping in? are you coming down to our mortal level

p.s. marvellous work as usual

cheers / Dave

vtsteam · « **Reply #46 on:** February 24, 2013, 07:43:29 PM »

Those jaws are fantastic -- holding that rule on edge like that.

I could do that in my vice.

But the edge would be serrated afterwards!

How about this (suitably scaled down, of course)?

Seriously, nice work again there Rob. An next time you're throwing a beaver on the scrappies, give me a shout first, I'm always up for bagging impractically large machinery....

Rob.Wilson · « **Reply #48 on:** February 25, 2013, 11:32:31 AM »

Cheers Lads

Hi John ,,,,,,, I could not be arsed to move it ,any way I need the space for more interesting machines

Cheers Dave ,,,,,,,, yes it would of only took me lest time than it takes to have a smoke too stick a new box together ,BUT it would not fit into my oven as the box would need to be at least 1 1/2 longer

, the box I have just fits , could do with a larger oven ,anyone got one kicking about ?

Dam now all I have to do is spray the job

Hi Ade ,,,,,,,,,,,,, there is a reason I could have it for nowt , the head and one of the power feed gearboxes are buggered ,spindle stuck in low (i think) , So probably more than you would want to take on . I will keep you in mined

Rob

micktoon · « **Reply #49 on:** February 25, 2013, 04:47:02 PM »

Hi Rob , you have been busy , splendid job as usual

, ............... I reckon the jaw you destruction tested would still weld up fine with a little patience

...................... I dont have much patience though

Keep up the good work

Cheers Mick.
