Yep, two links between the bar and the bolt! Free floating...Geez you took some great pics!Pete
By Jove, Looks like Mike cracked it!!Had both the PC & my phone open last night, so I could zoom in on phone to the earlier pics, pretty hard to see but your latest pic shows it well...well better! The tar spray makes it hard to pick the detail. One more thought....would that little short bar be free to pivot just enuff to allow Bar B to maintain its position as it as the latch would keep it from moving anywhere? Looks also like the Bar F "support is "L" shaped, the low side the pivot point for the short bar & the long leg the anchor point for bar F.Keep up the good work...the turtle head is looking good!Cheers Kerrin
I believe that the "F Bolt" is a pivot too, and that explain why they needed the "F Bar" to support it.One link will not give a parallel movement, but two can - or in this case a short link conneted to a "link" that has an offset and it can turn on a pivot.Sorry but no way of making a drawing to post here at work ....
Ah I think I got it now - the problem was that I "Ass-U-Me-d" that the bar across the latch and the latch solid fixed together sorry
Chris, can you do an animation in your software to show the link movement(s). Still trying to wrap my head around it all Bill
Hi Chris,As you know I am trying to draw the 19-RB. I have revisited your Marion thread and see that in posts 208 and 214 you have drawn the tracks in, I presume in Fusion 360. How easy was it?Inventor seems to have a mind of its own when attempting to draw anything similar it has all sorts of design assistant options for roller chains, v-belts, gears etc. etc . . . All the Utube videos on Caterpillar tracks in Inventor are based around modern track plates. Consequently the programme appears to force me into using the roller-chain method. I have Fusion 360 as well and am wondering if the drawing is simpler. I can draw the sprockets and as you have seen the track plates but it's the assembly of the 3 parts that I cannot yet solve.Perhaps Fusion allows the use of a path to generate the track assembly.Do you have any thoughts?Best regardsJerry
Chris, I dare say this will most likely be more spectacular than the Lombard, if that's at all possible.I really enjoy following along with your construction processes because I learn something new every time.gbritnell
