    Thanks Paul, I used 7075-T7 so I won't have to worry about them bending , They are massive, the outer diameter is over 1" . Anyway managed to find time to make the upper pivot clamps ..

    Finished the landing gear . can't believe what they ask for these thing ,only takes a couple of hrs to make them by hand ,and $30 of material I had laying around .I think I should sand blast the oleo joint to make it look more like cast .weight is 9 oz each and have 2-1/4 inch travel ..

    That’s going to be a sweet airplane Roger, especially with that motor. So cool! You must have your own lathe to be cranking out beautiful struts like that. Wow! What kind - size lathe you got ?

    Re: Hostetler 30% Chipmunk

    Thanks guys , these are the machines that do all the work The mill is a full sized Millrite , forget what size the lathe is I think 14"x 48 ""added digital readouts to both . the readouts on the lather are for a wood working lathe and are quite inexpensive but work very well ,down to .0005". Next I will be sheeting the fuse ,not sure how to go about it , such tight curves and the Balsa they supplied is like maple LOL. even after replacing all the Balsa,1/8" is pretty thick for those curves ., I am thinking about using balsa 1" strips . Has anyone tried doing sheeting that way . cheers Roger ..

    Re: Hostetler 30% Chipmunk

    Beautiful shop tools Roger. Your work shows me that you’ve got great tools and you know how to use them . I have a Force 14-40 lathe ( cheap Chinese knockoff ) but it works great for all my farm machining and hobby stuff I have to do . Would sure like to buy a milling machine too , but alas , it’s tuff on the farm , ha ha . Really enjoying your build so far.
