Zeppohoj Posted September 15, 2017 Report Share Posted September 15, 2017 Hi! I wanna make a soft plastic hand injector. I like doing my own tools etc. The price in Sweden is just sic so buying one is not an option. Im thinkin big coppertube for the heat or maby just alutube. What material is ok to use for the rest of the parts? I'll be using mostly handtools. I'll make my own vac50 molds. I need your brains for this Any idés?

Anglinarcher Posted September 15, 2017 Report Share Posted September 15, 2017 I have seen something on YouTube about making one, but the guy had a metal lathe. Still, check out YouTube and see what you can find out. I have given it some thoughts as well, but safety is pretty important so I have not followed up on it. 1 Quote Link to comment Share on other sites More sharing options...
Cami Posted September 15, 2017 Report Share Posted September 15, 2017 Two options. Have you ever thought to use a silicone syringe for cakes? I'm using my 200 ml silicone syringe from several years without problems. Second you can try to buy an aluminium one 175 ml from Baitmold.com for less than 30 €.

Zeppohoj Posted September 15, 2017 Author Report Share Posted September 15, 2017 Anglinarcher: Yes but didnt find any good ones. Do you got a link? Cami: Ok thats an option, is it safe? Dont wanna burn my hands. I can buy one but dont wanna spend any when I can make my own from scrap. Quote Link to comment Share on other sites More sharing options...
Cami Posted September 16, 2017 Report Share Posted September 16, 2017 As said I'm using the silicone syringe from several years without any troubles, safety issues included. The conical edge, as the piston, is in hard ABS plastic and you can adapt it to several casting doors. I added a thermo resistant O-ring to the piston. My cups are also in silicone with a plastic handle (for a microwave hoven of course). Surely you have to use thermo resistant gloves, as with an alluminium injector. Bye.

Cub48 Posted September 16, 2017 Report Share Posted September 16, 2017 I made one out of a liftgate shock it worked great for years. I bought a round piece of solid aluminum to make the tip. Cub48 Quote Link to comment Share on other sites More sharing options...

I have not looked for one to make in some time. The cake syringe looks interesting, but for safety, I will probably get my next one out of metal. I am currently using a hard plastic one that is no longer sold. Quote Link to comment Share on other sites More sharing options...

Cub48 Posted September 18, 2017 Report Share Posted September 18, 2017 It is a shock the oil had leaked out i cut the end off it has a aluminum piston with an oring i work at a Chevy Dealer so mine did not cost me anything we replace them when they go bad. I used mine a long time until i bought one that was machined from Bass Tackle Molds. Get the longer one if u want to buy as like now i have 4 molds and the one i have will not shoot all 4 molds without refilling.

Cub48 Posted September 22, 2017 Report Share Posted September 22, 2017 The shocks i use are the ones that go bad they still work good for plastic . The oring can be replaced on the piston. If u know a auto mechanic he may have one lying around for free. Cub48 Quote Link to comment Share on other sites More sharing options...

Cub48 Posted September 23, 2017 Report Share Posted September 23, 2017 I sawed the end off. U can screw the end off the rod. The piston and rod will slide out . Clean up the surface where u sawed the end off . Bevil it a little where the oring will slide in ok then find u something that will fit in the tube tight i bought a round piece of aluminum and sanded it down to a tight fit fixed the end where it fit the molds . The tip has to be a tight fit or it will suck air unless u stick the end passed the tip. Warm the injector before u shoot and u can keep shooting without cleaning.
