Merlin Posted November 17, 2015 Posted November 17, 2015 I have a 1.75 inch crossette pump and 1/2 inch plate from Wolter. I dont want to ruin these so I thought I should ask someone who is knowledgable.I want to add a metat FeTi or aluminum or fire fly to pumped stars or comets for effect. Am i correct to believe this could ruin my plate or pump due to binding?
dynomike1 Posted November 17, 2015 Posted November 17, 2015 I have been using Ti in my1/2" star plate and it doesn't seem to hurt it, on the other hand i scored my crossette pump. I didn't have to make but 1 star and i didn't think i was going to get the star out. My star pump is brass and my crossette is aluminum.
Maserface Posted November 17, 2015 Posted November 17, 2015 its all about clearance, you dont want to pump any metals that are similar in size to the clearance on the pump, else they will migrate between the rammer and sleeve and cause a nasty jam. You can use particles much smaller than the clearance, and much larger than the clearance, though. A solution is to add a small amount of non-metal containing composition right before you pump, to act as a small barrier; similarly you can use a paper disc that fits nicely inside the sleeve as a piston/O-ring. 1
calebkessinger Posted November 18, 2015 Posted November 18, 2015 Shape of the ti also It doesn't matter what any of the pumps are made of if some metal particles work up between the sleeve and the piston. When you finally get them apart they will look like an alligator ate them. I use a disc as a wiper on my pumps to clean the sides as you go. Just place it on Top of the comp. Working on an idea for pumps with actual wiping tips but got distracted making some other stuff.
Peret Posted November 21, 2015 Posted November 21, 2015 I jammed my crossette pump with titanium, the first time I used it. The solution I found was a hard rubber tap washer that's an interference fit in the sleeve.
Merlin Posted November 21, 2015 Author Posted November 21, 2015 Does anyone know if firefly al would cause binding in a Crossette pump?
Carbon796 Posted November 21, 2015 Posted November 21, 2015 It shouldn't cause an issue, weather its a crossette pump, cavity pump, standard pump or star plate.
