|Thread: Alloy joining|
Yes not done it yet about sums it up ,my welds are techno weld rods ,just use a stainless brush to clean the area and away you go,just heat up the parts to be joined and keep rubbing the rod along till it starts to stick a bit then heat a bit more and run the rod along ,but keep the flame away from the rod ,the heat in the alloy makes it work not the torch,like l said in my first post l took a big hammer to the test weld before it would break ,have also been testing with 1mm thick plate just using a small blow torch and it works great plus it drills and taps ok so one can fill holes etc file flat and away you go,after playing with test bits then the job l needed done still have about half of one of the rods left,you get five rods and a s/s wire brush for about £20 to the door, so well worth it to have in the work shop,it even worked well repairing round a bit of old die casting just to se if it would and again great,makes a change to se what it says on the box indeed works.
Needed to join some funny shape alloy bits together, so used some rods that you use a blow torch to weld them together,well am so pleased with it ,it opens up a good way to join alloy parts together,l even had a go with some crappy cast alloy ,for the test used 6 mm and some 10 mm plate , and had to beat the hell out of them to break them very pleased .

Thanks bill ,l feel a right fool now why l did not think of looking on there in the first place, thats great they also list the chain in 3mm ,it looks stong so think l will go for the 3mm,again thanks.
Hi all ,am in need of help finding some chain for the steering on my build,l am after 24 inches of 1/8" plain link chain,have mailed a few firms but none have it in stock and do not know when they will get more,then a couple say they can supply but have to buy a whole reel of it,so am stuck,theres lots to be had in the states but none happy to ship to the uk ,a mate of mine said he will post on the HMEM site for me to se if anyone can help there,so any thoughts please.
|Thread: Tailstock indexing|
Thanks hopper ,my barrel now has a scale,likie you said simple to do.
Thanks bandersnatch l agree am quite happy with the scale on my southbend ,but there is no scale on my myfords tailstock barrel ,so that has always been a problem,mybe l should try an get a a s/h barrel for it,but that can wait till l have got a degree in rocket science.
Brought a book the model engineer vol.100 jan - june 1949 ,and am reading my way through it an laughing at the ads for the prices then ,but have found a bit about making a indexing dial for the tailstock,has any one made one of them ,l seem to get trouble drilling holes to the right depth ,and in the book say that you can get the depth dead accurate,he worked out for the gradutions by the thread on the barrel being 1/8" pitch then 125 divisions = 1 division being 1 thou,perhaps one of you clever people can say what l would need for the ml7 ie divisions.
Well with luck l have sorted them out,striped them apart ,and junked the washers and have made new rubber ones,as for the needle a good clean with wire wool an a small tap to seat it and its has been fine for hours now so time will tell,would l buy them again nooooooooo .
