We spent a week doing a cycle of applying hydrochloric (muriatic) acid with hypodermic, washing
, then acetone, then releasing oil
, then heating
. With each cycle we could move it a fraction more until it opened enough to get more acid in to dissolve calcite. The tolerances around jacket at front are so tight it was seized with calcium carbonate. We think we are going to tap a hole through jacket into which we can screw a grease nipple to keep inside pumped full of grease. That tapped hole can be blocked with a grub screw.
We had a couple of emails with Gori in Denmark
, but they don't seem interested in ideas to improve their product. We like the dual pitch
aspect and overall find the Gori prop an improvement on our previous Maxprop, apart from this issue of seizing up which hinders removal
. What are your thoughts on reassembly with a view to making it easier to take apart next time? Oh yes, we needed to repair the supplied C-Spanner twice, and use long torque levers to make progress, bronze hole got distorted.
