seb Posted January 14, 2011 Report Share Posted January 14, 2011 Hi Guys I thought I would share what I have been up to. So far I havent completed my shot maker but I have a littleton pan I am going to use. The ramp was very bumpy and rough on it and the edge was very rounded so I thought I would machine it. I also have a couple of questions for anyone with a littleton. What angle is the heating element? I have heard 30 degrees mentioned, the ramp is cast already at 20 degrees to the pan so if I set the pan at 30 the ramp will be much steaper, could someone have a check for me please and see if it is the ramp or pan that is 30 degrees. I also have a digital temperature controller (PID) and thermocouple, relay etc to build into it to keep the temperature spot on but forgot to take a photo of this bit. If only littleton had drilled the dripper holes level! Seb Quote Link to comment Share on other sites More sharing options...
snarepeg Posted January 15, 2011 Report Share Posted January 15, 2011 Hi Seb. Let me know how you get on with the pan, it looks better now than it did, never got round to useing it, came with a littleton as a spare but cannot vouch its pedigree. Money refund iff no joy. the ramp was about 30 deg from memory. atb. john Quote Link to comment Share on other sites More sharing options...
seb Posted January 15, 2011 Author Report Share Posted January 15, 2011 Hi John I am sure it will work fine once I finish building the rest of it. Seb Quote Link to comment Share on other sites More sharing options...
seb Posted January 15, 2011 Author Report Share Posted January 15, 2011 Coolant tank nearly done My littleton pan has a hole in the middle so I am using it for bolting to the element, if it doesent work I will weld it up. Quote Link to comment Share on other sites More sharing options...
Floating Chamber Posted January 15, 2011 Report Share Posted January 15, 2011 (edited) I seem to recognise that dripper, Seb! Why don't you follow us home tomorrow and you can measure the angle yourself (once I've dug out the Lyttleton).

seb Posted January 15, 2011 Author Report Share Posted January 15, 2011 That would be great, I will bring the angle measuring gadget tomorrow. Seb Quote Link to comment Share on other sites More sharing options...
snarepeg Posted January 16, 2011 Report Share Posted January 16, 2011 Seb. Are you going to ladle the shot out of your tank?? What coolant are you thinking of using, (theres a lot out there), are you doing a cilculation flow?? keep the photo/s coming it looks very interesting. atb. john Quote Link to comment Share on other sites More sharing options...
seb Posted January 16, 2011 Author Report Share Posted January 16, 2011 I am going to have a couple of catch baskets, the main one to catch the shot and another underneath to catch shot while I empty the main basket. I still havent located any mesh fine enough yet to line the catch basket with. I am going to try fabric softner as the coolant. I might eventually build cooling into it. Either cooling the coolant directly or having some sort of heat exchanger coil in the tank. The temperature controller has a smart function that sort of learns when to switch the heater on to keep the temperature exactly right, hopefully within 2 degrees!

Floating Chamber Posted January 16, 2011 Report Share Posted January 16, 2011 We use the expanded aluminium mesh (used with resin when repairing motor car body panels.) Make a bottomless basket from thin ally, then pop-rivet in the mesh floor. Quote Link to comment Share on other sites More sharing options...

seb Posted February 19, 2011 Author Report Share Posted February 19, 2011 I haven't had much time to do a lot to the shot maker but got the temperature control finished today, just have to work out the ideal temperature. I still have to make the shot basket then I can give it a try. I also want to make a bracket to angle it properly. Quote Link to comment Share on other sites More sharing options...

seb Posted February 20, 2011 Author Report Share Posted February 20, 2011 Ran the shotmaker today for the first time. There are a couple of problems, three of the drippers need tapping to keep them running. The other problem is the dimples in the shot. This must be down to the coolant, I have been using fabric softener from Aldi. Anco so soft is the brand and I used it neat. Maybe its a bit thinner than other brands. Are you guys that are using softener using a different brand to this? I might try raising the coolant temperature a bit to see if I can get round it.

fruitloop Posted February 20, 2011 Report Share Posted February 20, 2011 what lead are you using and have you added atimony Quote Link to comment Share on other sites More sharing options...
seb Posted February 20, 2011 Author Report Share Posted February 20, 2011 I think it is all roofing lead, I haven't added anything to it. Seb Quote Link to comment Share on other sites More sharing options...
fruitloop Posted February 20, 2011 Report Share Posted February 20, 2011 (edited) i think what is happening is when the lead cools it shrinks slightly and the out side of the shot is set and when the core cools it creates a sink dimple but if you add atimony (dont go with the spelling)as it cools it exspands slightly and removes the dimple thats why printers use to use it so when thay cast the type it filled the mold. i might be wrong p.s. the shot looking good Edited February 20, 2011 by fruitloop Quote Link to comment Share on other sites More sharing options...
