that makes it perfectly clear dont it.

Sure - now let's see it develop.

oh its half built.

iv done almost all i can until i get the remaining parts.

i managed to get the bearing of the hilux axle this arvo, they are a press fit i have to heat it and belt it with the block spliter to get it off. need a new bearing for it now.

will take that in monday to get spline machined, and pick up teh last parts,

also need 4 track wheels duno where i can get them thow.

Well then that's more than enough to show some pics then

Seriously it's good to see some pics along the way rather than just showing the finished product because some stuff gets hidden on a finished product.

Whenever I reckon something is half built its probably about 1/4 built, and even when I reckon I've finished there's always one or two more things to do.

i took some pics this morning not mutch to show its just rhs welded up

teh main frame is done. im working out shat positions now. iv run into a few snags with that, my hilux rim is to big diamiter and dosent leave room for the otehr wheel, so iv found a 10" pulley off the old chaff cutter that ill bush up to fit.

it will work better anyhow,

once i get the bits i need on monday ill be able to put all teh shafts on and have the head working, then i just gota put it in place lay out the track and build the carrigge.

still undecided on wht sort of headblock to have on it thow.

more pics when i get the shafts siting right.

here you can see that with the split rim on there isnt enough clearance underneath. as teh pulley needs to drop/raise about 70mm to tention belt or run on rim.

so i got this 250mm pulley to go on the shaft. its got a 50mm bore and the end of the shaft is 40mm so ill get them to bush it out when i get the spline cut on the end.

Attachment 150468

be putign teh smaller pulley on it means i can lift it up, and put it threw teh rails, witch meas i gain about 7" or more underneath.

Coming along well - I'll have to see it when it's angry though

got the last of the bearings today.

and 2 of the 5 belts i need.

will make some progress when i get time maby tomorrow arvo.

can mount the shafts ...... no i cant i forgot to get bolts.

I'm just wondering how it will work succesfully & why a bench with trolley set up would not be considered. With a lot of mills closing down they are not hard to come by for a few K.
regards inter

what type of bench are you talking about?

i considered a floating top bench, but went this way instead.

it will work just like any of the old o even new headsaws work.

just like a medows mill - dad used to have one of them then we baught a kara 2000 and about 12 weeks latter teh council shut us down.

same setup as a frick mill.

Thats live sawing on a breakdown type carriage saw, not really successfull on high tension Aust' HWDS.

breakdown process is teh same for hardwoods no matter what saw you use. sept a mobile where you have to work backwards.

#1 saw breaks the logs down #2 saw mills them into boards. #3 resaws small peices.

still unsure of what kinda saw your thinking of inter.

I'm not much good with numbers or whatever when it comes to saws because as we can see it changes from place to place, mill to mill, state to state. From my experience in traditional small mills there is a breaking down rig consisting of a log dogged to a carriage passing by either a bandsaw, single or double circular saws, like the youtube video above, except that for Australian Hardwood logs of an average size the saw will pass as close to the heart leaving it out of the slab, then the log is rolled onto the cut face & passed by the saw again as close the heart, this is repeated untill a square baulk is left containing only heartwood. Slabs of a managble size are sent on green chains or oiled skids to a resaw breast bench with trolleys either side. If it was a larger setup there would be 2 resaw benches, the first bench just sizing & straightening the flitches then the next just ripping into boards or whatever is required. This milling method is called sawing around which relieves most of the tension of the finished sawn timber.
What was shown in the video is what is called live sawing, which is sawing from the outside of a log board by board to the heart. Might be good for timbers other than Aust' HWDs. If you were to do that type of cutting on our HWDs the boards will all spring away from the heart just like cutting them with a swing mill, thats why I can't understand how that saw setup is going to do anything more than the lucas mill you have already.

thats what this dose.

on a bench mill you cut inside out on a mobile you cut outside in. normally you would take a small slab off the outside edge, then take the side keeping teh desired distance from teh center of teh log so you can get a deck from around teh heart, if you need 8" boards you cut 4" from the heart.

then you repeat for the other side. the flat peice from teh center is then trimed off teh heart.

each peice as its cut is put on to coveyers / skids or whatever, any big peices come back to teh #1 untill there small enough to handle on teh #2 bench.

teh smaller peices and slabs go down teh line and get sent threw the #2 bench.

i was not suggesting to cut like in teh vid i was just showing the style of saw.

the entire process can be done on a small #1 bench but its faster with multiple benches.

the #1 benches at high production mills work on a crew of about 5 people, 2 benchman, a hobman, a tailorout and a pullout. i have seen these mills wiht 150hp 3 phase motors running them and you couldnt run as fast as teh log goes threw the saw.

first job for this one will be squaring pine logs for my veranda rails, i also have a lot of square posts to cut.

then i might get time to do up one of the old #2 benches. so we can up production.

I have not seen a high production sawmill working like that for probably 20 or more years, I should get out more often before they completely die out.
keep the pics coming.
