Darren,

They are called transfer punches, and worth their weight in gold.

You can buy all different sets, Imperial (the one shown), metric and drill sized. You can get them cheaper than this by searching around, and for the cost of them, you couldn't make them yourself for that price, by the time you bought all the diffent sizes of silver steel.


Ralph,

No vice involved, just plywood or hardwood (shaped), a couple of panel pins, some heat and a gentle touch.

When I get time, I will make up a little post to show you how.

Darren:
You just can't invent anything these days can you John...... :D

SPiN Racing:
VERY Nice!

Loving it.. (Work kept me off the board for the last few days)

Im thinking one of those is going to be a really cool item when complete.

I repeat this on all the sites I have ever belonged to, when someone comes up with a statement like yours.

Mechanically, there have been very few new real inventions. Just old ones that have been rediscovered, updates to old designs, or ones that were designed but couldn't have been made reliable in the past, but can be made now due to materials and technology advances.

The Victorians and before were a real brainy bunch. Bring those people into this era, and I am sure new inventions would be popping up every day.

Right... A few replies....


Darren,

I am not intending to have to repeat the hole marking, I just think I could if I needed to. The transfer punches were in the head at the time but I have non nor the cash to buy any right now. Not even sure if they do any that short?

I know this was at John but in answer to the invention statement... There has to be something to fix the doodad with a watchamacallit faster and more efficiently than with a thacktwacker? doesn't there? ... Also I have things on my shelves that I'm still searching patent logs about before I part with my hard earned!  :thumbup:
 (Top secwet, you know the rules? Tell anyone and your chances of the patent are void!!)

I'm waiting patiently  :bang:      :)




Scott,

Glad you like it so far.  :)
 
I'm hoping that it looks half as cool as some I've seen... As I said I think the prototype will wobble a bit. But I'm on my way to curing that in the next one :dremel:



Right one more reply to make and I'm off to the pub  :thumbup:



Ralph.
