  1. Hi Ron, I have a Sherline mill also.  That chuck usually comes with a draw bar (threaded on one end and a bolt type head) that you put in from the top of the spindle assembly.  I partially engage the thread of the draw bar into the chuck bore, give it a tap or two with a small rubber mallet (small hammer will work also) which usually disengages the tapered (morse) chuck head.  If you don't have the draw bar, putting a metal rod of suitable OD down into the spindle bore and tapping that should also work, BUT put a rag or something under the chuck so that if it dislodges completely, it will fall onto a padded surface and not damage the cross-table or the chuck etc.  The rod could be one of the many different bars/rods provided by Sherline, but should be a smaller OD than the bore, but bigger than the internally threaded bore in the top of the chuck (so that you don't drive the bar into this and damage the thread).

     

    I hope that resolves the issue for you.

  2. Hi Clovehitch.  I had to do these for my build at 1:72 recently.  I found I had to use very dense grained wood for any success. My method was to first file flats on either side of the boom inner end.  To make the jaws I printed scaled copies of each jaw set as templates l(that is, the jaws as a full integrated piece). 

     

    I thicknessed the wood to the appropriate thickness, and pasted the paper template onto it; and double sided taped (low tack) a sacrificial thin piece of wood under it to keep a clean cut.  I then cut these to the required shape following the outer lines.  Once cut, I sliced these in half to get the individual jaw pieces and sanded the centre cut back to the required line (to allow for boom neck thickness and taper. 

     

    I removed the template but before separating the sacrificial piece away, I drilled holes at the required places to simulate the through bolts (leaving the sacrificial wood in place helps with protecting these thin pieces.  I then removed the sacrificial piece and edge glued (two part epoxy for strength) to the flats on the neck being sure to keep them aligned.

     

    The following shows my test boom to prove the method and the final results.  I hope this helps?  The outer reefing combs look slightly large, but at this scale they are quite small and look better scaled to the naked eye.

     

    cheers

  3. Your build is coming along very nicely Harry; looking good.  WRT deck furniture,  basically followed the dimensions given by Marquardt in his drawing (at scale) in his "Capt. Cook's Endeavour" Revised Edition.  The exceptions being that I waited until I had placed the steering wheel and other deck equipment before making the skylight to fit. 

     

    cheers

  4. Hi Ian, overall your build is looking great.  One small point that may/may not bear further consideration is the motion/force of the bow wave on the verdigris seen on the ram.  Would the leading edges of the ram be more 'clean'?  I would not say polished as these would never have achieved sufficient speed to polish the edges.  However would a gradient leading back from the leading edges be more realistic.  That said, if the vessel had been alongside for a while this gradient would be gone but more salt/barnacles seen.  Only offering this as you asked :) and may be a little OTT.

    cheers
