I'm attempting to fabricate an instrumental insemination device, can anyone give me the ideal inside diameter for the tube that holds the queen?

Yes, it is possible to even “free hand” inseminate. It takes a little more skill and a lot less coffee.Hi JSL
would you say with a steady hand that one could line things up without a micrometer setup?
Got you on the fluid hydraulic model, on one of the videos it shows someone pulling the semen with only a small amount of saline above the main body of semen, maybe this is where I got swayed off of course.
Is it absolutely necessary to filter the saline through the 0.2 filter to sterilise it before drawing the samples.
I have the pieces made for the syringe used with my instrument, but you can fashion something similar out of a 0.25cc or a 0.50cc insulin syringe which are pretty common. A 1cc will work too, but it is a bit large to get very good control. If you have a mircometer to use, an all glass syringe and glass plunger would work pretty slick and be very accurate for you. I prefer to make the plungers using a threaded rod and an o-ring for better accuracy. Even the little bit of lay in the rubber and plastic on a standard disposable syringe has a good bit of play in it. It can work, but to me the lag in response is frustrating.Do you have a good supply of the ready made tubes with the standard syringe connections or their listing name. I could make up these using micro bore and silicone bungs, but the ready made is so much easier and looks better.
Yep, I call them old fashioned, but I suppose they are not... I have one around here somewhere, but you can buy the metal micormeters. They give you a very smooth thread and movement. Or, just find a nice piece of fine threaded rod that will fit in your syringe. It does not have to be fancy. SS is great, but brass or nylon works too, especially the nylon for a smooth movement. There are lots of ways to go about it, just depends on what materials you have handy.How about the larger micrometers as Pete suggested to me, the syringe could be made to fit in the tail end side and then mount the whole unit into a block.
