This is kind of the idea, a crude version, I'd push the weight into the hookbait, with luncheon meat it is just a case of luncheon meat on one side with half a pop up on the other with the hook on the side of the pop up, you have to play around with the size of weight and amount of meat to make sure it floats but is pretty easy.
Using mesh or tights isn't too tricky. Tights are a cheaper way to go but there is more faff though.
This is what is use with arma mesh. It is a syringe from my boys calpol with the tip cut off. Makes a bait of about 15mm [emoji12]
