yes, i am looking at the hydraulic on both tractors and the log splitter
that i built. the log splitter has a 10 hp briggs&stratton engine
driving the 15 gpm hydraulic pump and a 5 gallon hydraulic reservoir. the one
tractor only has an 6 gallon per minute (gpm) hydraulic pump. i am looking at
using a prince gear hydraulic pump to increase that tractor's hydraulic
unit to 21 gpm . mscdirect carries the prince hydraulic gear pump.

my friend gary, a disabled mechanical engineer, is designing a wood
lathe to connect to the 3pt hitch and use the hydraulics to power the
lathe. gary, has volunteered to make the porch columns for the new shed.
he needs to build a wood lathe to work 4x4 by 8 ft and 6x6 by 8 ft at a
slow rpm. he is in the model making stage. i have suggested to him that
he make the columns in pieces and put together to make the required
height. gary, wants the challenge that designing the lathe and the actual
making of the columns offers him. gary, was side lined by a brain tumor
several years ago. no one wants to hire him because he has seizures at
times and may fall down. gary, used to sit in his townhouse all day and
play video games or watch the sci-fi channel. now we all work designing
projects either for the new shed, tools that we need, or tools for the
ships.  gary's wife has held a workshop for the caregivers of the
disabled members of the crew. the caregivers are as much a part of the
crew as are the disabled crew members. when gary and i are working
together his wife gets a break from the routine to go get her hair done
or go for a day at the health spa for a massage and facial.

we may all be damaged and broken but we are not trash to be discard. we
are just as able to work and contribute as any person who does not have
to physical or mental challenges that we do. reality is that no one
except us believes that. the americans with disabilities act is not
worth the paper it is printed on. employers always have a way to get
around hiring a disabled person.
