Mill stop....

Hi Ralph

Just had to add my two penneth....(is that how you spell penneth ? ah well never mind). I made a backstop some time back but mine ows more to the Fred Flinstone school of engineering design. Does the job but every time I use it I will now be overcome with shame. Brilliant job Ralph and inspiration to do better next time.

Scott.... Sorry but  :lol:   I've been doing similar for near 3 years!!!! (thankfully I haven't made too many repeatative parts) Well I've been told that it was worth it's wieght in gold.... So I made it both heavy and sparkling  :thumbup:



John,

Thank you.... Never thought of searching for "backstop" ??

I know you have seen Bog's version of this so you also know that it only has to be functional.... Your's obviously does it's job very well looking at the Halo run   :headbang:

All the shiny "artsy fartsy" (Thanks Ian!) styling in the world wouldn't have made it create your Halo any better  :thumbup:

Penneth looks good to me  :scratch:   :)

I will just add a little bit here.

I have seen on other sites, backstops that have been all singing, adjustable in every direction, bolted as an add on to the vice, even stirs your coffee for you.

But where most fail is the diameter of bar that they use, some of the eejuts have 1/2" bar as the stop. Totally useless IMHO, 1/4" is the max size you should use, and like Ralph has done, turn one end down even smaller, just for those really small jobs. It can be a bit tight sometimes if you are making really small bits and have to squeeze in between the jaws. The easy way would be to make your clamp block to hold bits of rod down to say 3/32", or even smaller if you have a need for it.

The stop should be as simple as possible and only needs to be just rigid enough, you are not going to be hammering components against it, just a gentle slide until contact is made.

You can buy ready made ones, and they are not a patch on what Ralph has made.

Mine is just a piece of workshop junk with a bit of threaded rod stuck thru it, but it has been with me for more years than I can remember, and it has never let me down. If it does the job, why complicate things.

Ok.... For those like me who do not really work well in fractional measurements I've done a bit of calculatoring (yes that is my new word!) and 3/32" = 2.38125mm  :thumbup:

Which is a good thing, cause the rod in the mill stop is a 4mm stainless bar turned down to 2.5mm at the end :)   (the bar it is up against is 8mm dia).

You definitely don't need to make one like this one... If we all made the same life would be boring!!   I just got carried away as usual   :ddb: 


I'm still yet to search for backstop.... Do you think I'll find loads? ..... I'll go see in a mo' :)

Ralph,

The reason for the fractions is our colonial friends, we've all got one now, they need to make theirs, and if I mentioned metric, they would have a lynch mob after me. :lol:
