[C320-list] linear drive

[Jeff Hare]

Hi, Use a cobalt drill bit, not that titanium junk. Dip the bit in oil and use a medium speed and pressures so that your chips are curls or chips, not filing size.I did not drill all the way through the post, instead, I drilled through the aft side and tapped it and used a large hardened stainless bolt.I did not want to risk missing the alignment to the exit hole.  Plenty strong..As for the Edson tiller arm, I cut off the end, drilled a new hole for the linear drive arm.  I machined my own bushing you allow tightening the nut on the bolt that the linear drive attaches to.I have pics I'll dig up..  I'll send them all tomorrow unless they are here on my phone..Jeff

That worked out well. How much trouble did you have drilling the rudder post?Thanks,Chris BurtiFarmville, NCFrom: Jeff HareSent: Saturday, June 6, 2020 11:42 PMTo: C320-List at Catalina320.comSubject: Re: [C320-list] linear driveHi Chris,It was a pretty straightforward project.  I have all the details on how to make it work.Used the Edson one but slightly modified it.  The whole system works like a dream If you're thinking of doing it, I'll get you all the details. Even have a CAD file for the reinforcing plate that any machine shop can whip up for you.  Several other owners have done this already.Jeff-------- Original message --------From: Chris Burti <clburti at gmail.com> Date: 6/6/20  6:53 PM  (GMT-05:00) To: C320-List at Catalina320.com Subject: Re: [C320-list] linear drive Jeff did you have to order a special length arm? The standard Edson 10” won’t fit CommitmentThanks,Chris BurtiFarmville, NCFrom: Jeff HareSent: Saturday, June 6, 2020 6:45 PMTo: C320-List at Catalina320.comSubject: Re: [C320-list] Fuel filter experimentThat has been on my radar as a project for some day.Only problem now is that I installed a linear drive autopilot and now the space it's more crowded...But that wall is really thin, so you'll want to glue/epoxy on something to mount it on..-------- Original message --------From: Jack Brennan <jackbrennan at bellsouth.net> Date: 6/6/20  3:46 PM  (GMT-05:00) To: C320-list at catalina320.com Subject: [C320-list] Fuel filter experiment The recent discussion on changing to a different type of fuel filter got me thinking. (always a dangerous thing …) So I went climbing inside the port  stern locker today as it rained and found what I think is a good location for installing a Racor 500 filter.The fuel line leaves the tank on my boat, reaches a shutoff valve and then snakes into the passage under the aft cabin to the Yanmar. On my boat, I can move some cables and hoses inside the locker and clear a space just to starboard of the access door that goes into the aft cabin. Right there, I can bolt the 500 to the bulkhead and have enough clearance both to change the filter on top and bleed off any water on the bottom.The spot is a little above the tank, which should be a good thing because I shouldn’t have to use the shutoff valve when I change filters. Just climb down into the locker and go at it. The fuel lines can be secure and out of the way along the bulkhead.In theory, I should also be able to reach the filter from the aft cabin, although my wife would kill me if I got diesel on the bedding.Any flaws in my plan?
