Posted April 27, 201113 yr well as promised i do have some pics to share but joined together to form a video i hope you can see the video all right, feel free to post your comments this is just the head of it, i have tryed to copy a real life one as much as possable its going to be a big model when finished but i think its going to be great when finished !!
April 27, 201113 yr Wow! This is really cool. Any motors running it? Kind of reminds me of oiling a car. I will love to see this finished.

May 2, 201113 yr Author I have finished the head of the harvester tonight please let me know what you think. Also i would really like to know if any body would like building instructions of the finished model when i finish building it,I don't want to wast time on making instructions for it if no one wants them,I have listed the 6 functions below that is in the head : open/close grab powered forward/reverse debarking wheels open/close chainsaw rotate bottom part of head adjust head angle rotate upper half of head Here are some pics:
May 3, 201113 yr Yes, I'd like Building Instructions for your Tree Harvester! There are real logging machines like this in the woods in the Pacific Northwest. They make QUICK WORK and are very efficient!
May 5, 201113 yr I would love to have instructions for the head. I had a nice design for telescopic grapple that worked real well but I couldn't find enough room in the crane to run a drive line to the head so it would have a leveling system for the grapple.
May 5, 201113 yr Author Ok thanks guys for expressing interest for instructions for my harvester,there is 1 wee issue though which is that the wires and cables do not go though the truntabble which means thay will twist ,when i am finished the whole thing i will look to biuld a new harvester head for it to fix these issues. I am working on the base of the machine this minute and should have it finished in the next week or so. I will start makeing instructions soon for you all just as soon as i get yet another book on lego softwear power tools as i lost the cd.
May 8, 201113 yr Author I have finished the base which has the tilt mechanism,i hope to have the arm finished before the end of the week. The to tracks are diven by worm gears which are then geared down just at the track sprockets,i hope to have the slew mechanism finished by the middle of the week. I could of had the track drives going through the turntable,but i did it this way as it was easy to do and also it adds a wee bit of weight to the base. Comments welcome!!
July 11, 201113 yr Author Very sorry in posting more pic's here is some progress: please tell me what you think , i will probably change the boom a wee bit,am working on the pump right now so the gearing will change,i think i have made it a wee bit out off scale but please tell me what you think about this also. sorry for the pic its not the best
July 11, 201113 yr I like it! That is a lot of functions you will have! Looks great! I wish I had some of those micro motors.

There is also a ram in the undercarrige to give it the thing tilt. (when working on the hills or slopes) The chain that you can see is the chain saw that works on a small ram athough it is not moterized it will turn a wee bit with the ram.

July 16, 201113 yr Wow i can tell this will be a pretty epic MOC when it is done! I forse a slight problem though with the tilting of the uppercarraige, would the weight of the machine cause the turntable to bend? Is the pneumatic cylinder strong enough to handle the weight of the whole machine tilting on just one cylinder? tim
July 19, 201113 yr Author Thanks for your replay sorry i coulsd no get back quicker i have done some tests and should be allright ,it would be easy to make changes to ether the top or the bottem if needed as well.
November 26, 201113 yr Author progress Changes i have made since last time: New boom New pump New slew ................ New every thing Edited November 27, 201113 yr by Alasdair Ryan
November 26, 201113 yr Looks fantastic so far, love the extending boom, compressor design also looks very promising.
November 27, 201113 yr I was looking on a facebook page of a lego builder and he is building a forest harvester to. Here is a picture of his claw, because i remember you saying that you were going to redo yours (inspiration). TechnicLee Facebook *EDIT Sorry the forum wont let me post a link of the photo so i will give you the link to his page instead. The claw should be the third or fourth photo down. tim Edited November 27, 201113 yr by timr
November 27, 201113 yr Author Looking great! I wish I had some of those pneumatic brackets. I got four sets of them........ Here is my facebook page while i am on the subject. My Facebook page
