    Cutting groove for O rings

    I need to cut grooves for some O rings, all on the lathe, these are quite small, 1mm width and into Stainless Steel (303) and need to be a really good fit. (Going to be holding 150BAR of pressure) What tool would be best, grind down a HSS parting tool is about the only think I can think off so...

    Any tips on machining Graphite?

    Hi, I am just about to make the piston and valve for a flame eater and I am sat here looking at a lump of graphite thinking I have no idea how easy or hard this is going to be. I need to obviously make it a good fit in the bore and also need to tap a thread through the centre of both. So...

    Anodising

    Hi Simon, I can't remember what the name of the other dyes I have used is, but I have stuck with the Gateros dyes as they work very well. Also if you contact them they will supply in smaller quantities as I only ever make up 1 litre at a time and you can use them over and over again, the last...

    Wire bending jig

    Anyone got any plans for a simple wire bending jig..? I need to bend some 2mm Stainless and would like to make a neat job of it so I thought of making a jig, at least it will get used for other projects. Can't seem to find any plans. Thanks Dave

    Nice job... Couple of questions.... In the dye for 45mins, wow, I normally only leave it in there for 10 to 15mins.... and you rinsed it after it had been in the dye, I tried this once and it washed out ALL the dye. After the dye I chuck it in boiling water to seal in the dye, did you not do...

    Hi Goldigger, sorry I have been off this forum for months and only just seen your post. Yes http://www.gaterosplating.co.uk is where I got my dyes from, but not used the kit, but I don't think you would have a problem with it, looks like a good way to start. Nice looking lights, with the finish...

    Anodising

    Just seen this. Vic, I have seen this before and normally, well, when I have done it, left the part in the dye to long. I have managed to improve it a bit using some very light polish, like brasso. Does take a bit of the colour out (excess dye) but it does improve it. Dave

    Anodising

    Yes, some of this I do in the kitchen. The Caustic Soda is done in the sink, there are some fumes that come off this so you do have to be careful, but it's all done quick, jug gets half filled from the hot tap and I keep the tap running, chuck in some soda and then the part. Part is in there for...
