the boom is actually weight balanced at the lift point pivot. stick and bucket throw it off though. can't really balance for that

it's surging because the original leim was designed for cyls 1/3 to 1/2 of what i am using. and for less of them. just not enough space for the fluid to go when the pistons push in. then when they push out, you have to keep it full past the 3/4 (more like 10/12) to avoid the pickup from getting dry, since the pickup is really 1/3 off the bottom. so really the design is only 1/3 of the tank being usable - pathetic!

the one that is in the wedico is the big version, both in tank and pump ml/m. however that is not available outside wedico kits.. that tank is actually as big as what i have right now, and still not enough.

i've fixed that with a yet another expansion of the fluid tank. (total 3x original capacity). i wanted to make a 10oz tank and started cutting it out, but as i lay the pieces together noticed that would have really thrown off my canopy and made it way unscale. so i dropped that idea for a yet another expansion of the miniscule oem one.

will try the oil for future taps. just that only time i used it is with carbide bits into hard steel due to heat. never even thought about aluminum, especially with hand tapping (tried machine tapping too but very hard to control blind holes)

i might have to limit the epa on the downward now. good idea
