I would like to know what syringe I should use to measure .21 size head buttons. Where to buy would be helpful. Thanks in advance. Richard
 
I get used insulin ones from a friend. I clean them in alcohol. They have a fine needle and I think they are 1cc but will have to check and let you know later. Mean while someone else will probably chime in. The liquid is also important in order to see as it fills. I use rubbing alcohol with red food die in it or I us coffee which I always have.

The 1/2CC needle works better than the 1CC. More accurate.
Crap ton on amazon.
https://www.amazon.com/s?k=1/2+cc+i...=1/2+cc+,aps,110&ref=nb_sb_ss_fb_1_7_ts-doa-pI was unable to find them by a single unit. I think I got 25 the last go round. Extra is nice to have. Using alcohol tends to rub off the marking on the outside after a while. So pitch it for a new one. You will need to get some number drill bits. I think I made my plate plastic with a #60 bit. The plate is about 3/16 thick.

For the best repeatable accuracy, especially for the small 3.5cc engine buttons, you'll want to use pipettes. They're inexpensive.

I use a .25" Lexan square, polished flat, with small hole to engage tip. Also made a small base with hole big enough to clear plug standoff on button, attached a bullseye bubble, fine thread cap screw in each corner to adjust level.

You'll never use syringes again.

Also, the volume of glow plugs vary by a fair amount.

Tim, am I missing something? I don’t see how/where you measure the volume?
Thanks John
 
Had the same problem John. Scroll down till you get to the pipettes section. Looks just like a syringe without the needle. Old man brain in effect....LOL

I like how small the needle is. It allow you to keep the hole small for filling. The surface tension at that size will keep the alcohol from coming out the hole. I have 2 hole in my plate. One to fill from and the other I place along the edge of the bowl. Plus you dont want to fill the hole in the plate. Gives a wrong reading.

Mine are the 1cc, a .5 cc would be nice on the smaller volume head. I usually put a piece of radio box tape over the calibration so the alcohol doesn’t smear it away. Another reason to use coffee.
 
Yeah I'm not sure how the pipette would do. Seems like a bit of an extra hassle to me but everyone has their own way of doing things.

I have a clear plexiglass plate with two holes as well. I push/ lightly stab the needed into the bottom of the glow plug to hold it steady while I fill the head. Once the surface tension lets go, it fills in a nice controlled fashion from the bottom up until the alcohol reaches the second hole in the plate. I use the rubber nose piece from my outboard starter to support the head on the table and hold it steady.

Do it a few times to get an average reading within 0.01cm^3, and you're good to go.

Got mine on Fleebay.

Send me your address John and I will send you some of the extra I have for you to try.

No, you're not missing anything..... 😂😂😂...... It was ME who missed something

and posted the WRONG link! (more) 😂😂😂

My deepest apologies, John......and thanks for bringing that up.

THESE are the ones I have-

Funny how omitting one word changes the whole planetary perspective.....MY BAD! 😂😂😂

Thanks, John......

This is a 5ml example......they all have 0.1ml graduations.
 
Thanks, now that makes sense. FYI to those who may wonder. 1 ml = 1 cc

John, thank you for pointing out my error.

Next time I unpack my 'cc'g bench', we'll snap some photos. I've only done my NR46DD buttons (turbo and std.) with this system, for now.
Been too consumed with getting all the proper mandrels together for this Sunnen P-180 Honall.

Have a Merry Christmas down there...guess it won't be a white one.
