Will this work?

I thought your PTW was your DMR? What's your DMR then?

ok these gears and this piston

will not work because the gearset requires you to have a half tooth piston. Look at the sector gear, the gear all the way on the right side. See how it has teeth going all the way around? Imagine that gear meshing with the piston.... if teeth are always making contact with the piston rack, how will the piston be released to shoot forward? The answer is, you need a half tooth piston. Because the gears are such a high torque ratio, both sets of teeth on the sector gear are the same diameter. So to make sure that the set of teeth that go all the way around (and make constent contact with your spur gear) aren't making contact with your teeth on the piston, you need to run a half tooth piston with them.

I think for the other pair, Dom is pointing out that the gearset does not require a half tooth piston, but one has been selected for it. This will still technically work, but if you can use a full tooth piston, you should. Gives you more surface area and makes the piston stronger.

compare the 2 pistons:

Normal (full tooth): http://www.airsoftpanda.com/product_inf ... 6e7qcn6cr3

Half tooth: http://www.airsoftpanda.com/product_inf ... ts_id/2090

Ok. I get it. I was kind of curious about that one gear set that required the half tooth piston, but I kind of dismissed it as something with the picture or something. I also think I caught the half teeth on the piston but than didn't set off any lights either. This has been a very educational thread.

@Star_Folder: It was originally in a TM G3SG1, now it is in a G&G full metal M16A3. It is a Systema drop in M150 GB w/ reinforced shell, MOSFET, bore up chrome cylinder, mushroom piston head and aluminum double oring sealed cylinder head, JBU half teeth steel toothed aluminum bodied piston, ball bearing metal spring guide, variable pitch M150, Hornbill 1:15 (bevel to sector, highest torque manufactured) helical gear set, 7mm ball bearing bushing, TM EG1000 motor, Firefly bucking and nub (both hard), and Promy SS 6.03mm. I should probably sell it since I never use it anymore.

@Sky: Planning on it.

This has been a very educational thread.

That's because I have a PHD in Advanced Teacherological Studies.
