Clamps

[Dalboy]

While working on the Farm Boy engine, I needed some clamps, so off I went onto a side mission to make some. These are Kant twist clamps. I do have G clamps, sash clamps and all sorts between but not suitable for my needs.
Well this is as far as I am at the moment, main frames made and 8 spacers (4 for each) still need to make 4 more but shorter. As well as the screw mechanism and jaws.



The camera makes the spacers look all different lengths, but I can assure you they are all the same.





More to come soon

I wonder, do I detect a form of CARVER CLAMP ?

They are like this ONE

 

[Dalboy]

I thought that I would get more done today, except that a leak in the kitchen put paid to too much work. But I did manage to get a lump of Ali machined down to 19mm square for the jaws, just need to cut and clean the ends down to the correct size.
I decided to do them to break up doing the spacers, which I will get back onto once the jaws are finished.
Not worth taking any pictures.

I had a dozen or so so of the Martek ones.

One moment, please...

I got rid of them as it was near impossible to tighten them without the two workpieces being glued sliding. They tend not to to stay square to the work.

These will be for metal working. Many metalworkers use them without problems, may be it is the glue which makes them slide, I will find out once I start to use them.

Well onto progress at the end of today between looking after the wife, watering the greenhouse and cooking the meals.

The blocks and short spacers started



One end of the spacers the thread is 4mm to give an idea of size



All the parts so far still need to make the screw mechanism which will be the next step

 

[Dr.Al]

I use them all the time for metalwork and they work really well. I've never tried them with wood/glue.

Really like Kant twist clamps, haven’t had problems with pieces slipping- find them much better than small g clamps in that regard.

 

[Dalboy]

Started on the screw mechanism, turned the spacers and drilled and tapped the larger ones for the screw, next I will drill the other spacer which will hold the end of the screw.
I have added a picture of one of the larger pieces with a ruler to give an idea of size.

 

[Dalboy]

Getting close to finish line, I need to strip and put some v slots in the jaws and also make the T handle crossbars.

I did the assembly to check everything was free and lined up all OK.



A couple of pictures with tape for size

 

[Dalboy]

Complete at last.







Yes, I could have brought a set,

If I had to buy all the materials and labour they would have cost more than brought ones, as it is most of the material I had in the scrap bin. The added bonus is I enjoyed making them, I learnt from the experience and learnt more from the odd mistakes.

To fully understand why a set of g clamps would not suffice I would need to see them in use . They do look nice though.

I'd struggle to say why, but I reach for the kant-twist clamps all the time when metalworking; either them or some metal f-clamps. I can't remember the last time I used a G-clamp.

Stick welding close to G-cramps is a pain. You spend as much time clearing weld splatters of the threads as you do working. Over time you destroy the threads.

Theese cramps solve that problem in an elegant way by moving the tread further away where the splatters have cooled somewhat and don't stick.


Well done Dalboy!
