So I need to replace a graphite gasket on my solder pump, the kit was ridiculously priced and the quote people are not responding so I bought a graphite plate.
I need to drill a few screw holes in it and cut a graphite sheet to a 5 inch circle. It does not look like the dimensions are critical, so I was going to do the layout with drafting tools. I am pretty sure its some what porous anyway, so I think it just needs to be bigger then the pump body.
I am not sure about how to go about cutting a circle, How does a band saw sound? It can be oversized or not exactly a circle because its just a gasket, so long the bolts are correct perhaps I can cut a square, or some kind of many sided shape, if the circle is deemed too hard.
The holes are like 1/4 inch.
Any tips for doing this? Can it be done on a mini drill press? I saw something on applied science but he used a router IRRC, my proxxon mill is too small.
I am going to only have 1 or 2 shots at this before I run out of material, but on the bright side it looks like a repair with epoxy or super glue is acceptable from what I have seen, so long its not in the very middle, where the rotor touches it.
