The whole thing isn't an easy machine job by any means. Congrats man, something else to proud of! You keep taking things to another level all the time, keep it up.
    I have the collets for it....but the head doesnt have much travel on my mill. Ive learned to tighten the crap out of the chuck otherwise the mill bit is gonna slip. ( i think im gonna get a mt2 quick collet) I also took small cuts. I just got my corner rounding bit in...can I say thats a pain in the ass to get right! omg....I think part of it is its kinda small...I may have to get a bigger one.......

      I wasn't thinking of the cutter spinning in the chuck, more the delicate ends of the dovetail cutter and the fact that regular chucks don't run all that true. The radius cutters are nice but definitely need to be set accurately to get a good result. I have a 2" x 72" belt sander with all kinds of fancy belts. The scotchbrite belt is a lifesaver and really cuts down time if your going to Polish. I would just use 400grit sandpaper as your finish on everything. It's similar to the finish you get when buying brushed aluminum sheets if your planning on doing more. You don't need another 2 plus hours for polishing on top of everything else! With all the work your doing investing in a 2" x 72" beltsander would be ideal. Great for custom exhaust work etc. A 3/8" radius cutter would be a good size and more forgiving by a long shot over 1/4" an smaller. Gives you more room to eyeball it and have a nice result. Drop my a message if you need ant suggestions as I have been machining for over 20 years as part of the day job and have all the stuff at home as well. I do work for myself and a few friends, like has been stated here nobody wants to pay the price it actually costs. Cost of the equipment, electricity and all the consumables like cutters, finishing supplies make even $25/hour from home hardly worth it. It's best to just do it for fun!

I had to teach myself along the way. I didn't have any plans or drawings of it....I winged it mostly along the way. I had my boat sitting near and was taking measurements along the way. Jotting down on a piece of paper. I had an idea of what I wanted and this is how it turned out. I'm extremely pleased with this first version. It paves the path for improvement on the next. When Dave emailed me back earlier he said the major thing is writing the program for it. I imagine that's going to take some time there. I don't know if thing will get produced, it may be too much of a pain and just not be profitable enough for him to fool with it. It would be really nice for you guys to have this available to you though. I'll be running it this weekend. I'm waiting on some parts from fightercat to finish it up. Should be here Saturday.
        Considering the MTC strut was going for $260, there is definitely some work involved.

          Looking good Travis, I figure it's just a matter of time till some one goes into production with a adjustable strut as there seems to be a need for it , remember necessity is the mother of invention !!

                That strut is a work of art in my opinion and probably worth every penny they are asking....but the average guys like us arent gonna spend that kind of $$ on a strut. I had been brainstorming and trying to come up with ideas and I found this MTC strut. I'll let you guys know how this thing fares in the next day or two. I'm gonna bring a few sets of batteries with me and get to testing!

                  I agree the price is high. they probably don't sell to many.

                      Thanks! cant wait to get this thing in the water....thats going to cut my prop testing and tuning down considerably!

                      the only thing i can think of....the rudder lowers with the strut and prop....im wondering how thats going to affect handling? I may have to end up making the rudder stationary. This just dawned on me lol. May or may not make a difference.

                        Very nice work Travis. Marty Davis made something similar years ago that I have been trying to get my hands on. His allowed for up and down adjustment as well strut angle. There is even some form of chart that shows the amount of change ( in degrees ) made by the number of turn increments on the adjusting screws. I may have a picture somewhere, at any rate- Looks Great

                            I would keep the rudder separately definitely the linkage might give you a problem also

                              I thought about that part...it has enough movement to compensate

                                Hat's off to you KFX & others constructively commenting on this topic. So many times people talk and wish but rarely get busy with making it happen. Appears a very solid idea so far. Hope it all comes to fruition.
