So I have a bunch of 1 5/8 4140 round bar and I want to make some heavy tong held tooling... I thought it would be kind of clever to make a die to dome the top and make the tong groove and isolate the lower "blank".... So I turned a part to make the impression and then stomped it into some 4340 blocks.... And after I did I thought that was dumb, I should have just made a spring fuller with stops to make the tong groove with and a shear to dome the end and lop it from the bar...
So even though I haven't tried this yet I think I'll chalk it up as a learning experience and move on... Just wondering how you all might go about it?

The large diameter is 1 5/8 the tong groove is 1 1/4..... lead in and out is 1" round.... the parent stock is 1 5/8....
Whatever you are, be a good one.

If I needed to do that (which I don't) and I had a lathe (which I do), I'd chuck the tools in the lathe and be done before your forge was hot. There is a place for everything and this is a place for machining. There's a time to fab and a time to forge and a time to machine. You'd laugh your ass off is someone machined a pair of tongs from solid, right?
I said if you have a lathe, remember.

Pretty much what Grant said.
These are made from 1" 4340. I machined the groove first in the lathe. Then if needed I upset the the ends using my 30T press and then if needed forged the ends to shape followed by a quick grind.
I used 1" because they would be used under a treadle hammer as well as a smalll PH. I kinda thought if they were too large/heavy they woould absorb too much of the energy in the blow. They were made "tallish" so they would reach "into" the work.
Yeah if I didn't have a lathe I'd do what you suggest with a spring fuller
I went on a big tooling odyssey on this job. Making the tools to make the fuller tools, making the tools to make the bottom tools, making the jig to make the tongs (i nearly decided to revamp my treadle but stopped myself ... for now) and then finally actually making the work ..... a lot of my time seems to be making the tools that make the tools that ...

Man I really like what you have done with that gate David...
Ok... well..... Maybe it stems from the fact I really dont enjoy machine work (It feels like work) but I see working under the powerhammer as play time... The thought of machining out 20 or 30 of these make me want to do something else.. But I guess If I just do a few at a time as I need them...
Whatever you are, be a good one.

Maybe David can find a blacksmith in his neighbourhood to forge him a nice backrest, ya think?

Wow, tough crowd. David, you better customize that freakin' bike or make sure it stays out of the frame. BTW, I like the gate as well. A bit delicate for your style...but nice.

Now come on Danger, I have at least put "custom" heated grips on it :smug:
Actually it's a time thing, as in I've none of it .....not a drop of it going spare.
I've also spent many (some may say too many) years in the past messing with bikes. But usually my hamfisted tinkering did more harm than good. Over the years I've broke down and come back with my tail between my legs (on a recovery van) from too many European countries. I bought this one from new 2 years ago just because I wanted to do some touring with the back up of the warranty ... it really is good for peace off mind.
Warranty runs out in a few months so will get out the vise grips :timebomb:
Actuallly if I can find the time, I fancy doing my Trident as a "Triton". 50's styled cafe racer with Norton featherbed frame and Triumph engine. Sculped alloy tank, drop down handle bars etc .......can but dream

It is a bit. This was a design definitely pitched at the female of the client couple. It's also a bit odd that it looks better as two half gates in the open position than a double gate in the closed position. There's a bit more work too on it yet but I'll post some constuction details when it's all done

yeah John clip ons ..... I wasn't sure if our colonial cousins would understand the term. I'm not sure they have the deep ingrained appreciation of the cafe racer we Brits have.:smug:
My Trident is a 73 T150V (three upright cylinders). I kinda find pre unit Bonnies a wee bit slow and possibly unreliable plus I think unit Bonnies just look plain wrong in a featherbed. They just don't fill the frame. Trident engine ticks all the boxes for me.

Since CAFE stands for Corporate Average Fuel Economy on this side of the Atlantic, David's probably right.

This is the next sportster project Joe and I have in the works...

This bike a friend of mine an ex co-worker bought new in 96.... He got in a bit of a bind and moved to west Virgina in a pinch... called me up one day and said hey wanna by my Harley cheap? When I got it it had fat bob tanks and all the cheezy gold "Live to Ride" harley crap on it..... the swingarm is scratch built with a three point forged 4140 pivot link and a R6 shock... Joe built the pipe, tank and rear fender...
I think we are going to stick with the same tires and go to wire/spoke Excel wheels for more of a street tracker look...
Whatever you are, be a good one.
