Thanks to all for replies....I will mill 60 thk. as suggested and I will be able to get at least 1 full width slab from each length .
Cheers.

I have access to a large blue fig log (silver quandong) about 750mm dia at butt and 10m long. I have a "lucas" style mill and was thinking of sawing this log into mostly 200x50 boards say 3m long....

Thanks Peter for the formula. I will trial it on a Yellow Stringybark slab dining room table I am working on.
My general questions....
1. Where would you use a water based finish ?
2. Where would...

"Dozey".....yes, soft half rotted areas! I was thinking that a runny 2 pack product would soak through/ impregnate these areas and stabilize them. Whereas, a no sag epoxy will not soak through porous...

Thank you gents for the replies.....
I have resurfaced the slab under the saw and now reduced to about 50mm thk. and also tidied up the natural edges. Looks good. I have decided not to fill the...

I have a large (1900x1300x75thk)odd shaped t/wood slab that I wish to make into a table. The table would be located on an outside covered deck, no sun but occasional rain drift/spray.
My queries...

Ok I see what the problem was....me not opening my eyes!!!!

The metric pitch ref late att to the lathe clearly states..."the sliding lever must always be in the extreme left position". See photo...

Thanks gents your replies. I see now that there was an earlier thread in 2013 by Vernon that fairly exhaustively (65 replies!!) covered this issue.

I was trying to make a flywheel puller for a...

After obtaining a 127 tooth gear as a result of an earlier post on this forum I now seem to have come up with another problem.

It would appear as if the thread chaser dial does not work for metric...

Thanks Carl,
A few more questions for you.....

1. What is the difference between a "bobtail", a "logging arch" and a "bullwheel"? Could just be one of those funny "State" things....like Flooded...

Weisy & John,
Thanks for your input to date.
I have a dozer and a 70 hp tractor but I am not keen on simply "snigging" the logs because of the damage done to the bush tracks. There are still deep...

John,
Thanks very much. The "Logrite" arch looks like it would do the job...

Has anyone made/got a 3PL log lifter/ handler for snigging large logs? If so I would appreciate some pics/ideas. I can start from scratch but if someone else has already gone through the ordeal I...

Silash,
I also have an "old Transtig 250" or maybe a "180" ??running on 3ph.
I am just a novice "tig" welder and must admit that I am having problems getting the hang of the tig despite many years...

Berrigan,
I have used 150 x 25 rough sawn boards off a Lucas for a couple of exposed decks. The tallowood boards were unplaned but I did take the edge off with a "pencil" round router bit. A 45 deg...

You're a very lucky man!

Please Bob, don't let those "Americanisms" creep into our Aussie lingo!!!!!

I built my own "swing blade" mill about 15 years ago. It has got a Honda motor (don't like B & S) and can cut an 8' depth. Also has a powered carriage.

I am just over the range from...

A friend/neighbour of mine has just purchased a 35hp diesel Woodmizer. I have not actually seen the m/c yet but I have to admit that the video clips look impressive. Very automated and easy to use.

I gather you guys are talking about the mechanism that raises/lowers the rails????
I'm thinking that this task is easier than the pushing/pulling of the carriage. For instance, once the rail height...

Yes I have braced the sides!

Ian, you were well out with your estimate of 5 walls. I have already done 4 and there is at least another 2 left in the original form!!!!!! The PVA paint is now...

Ian,
I have both made my own gabions and used bought ones.

The home made ones were from ordinary heavy duty wire netting and turned out more like a sausage than a basket! However, they were...

Too late China! I've got it made from 6 x 1's that I had lying around.

I am currently making a large (2700 x 900 high) hardwood form for 600 dia culvert pipe headwalls. I will need to make about 20 of these headwalls so, to prolong the life of the form I was thinking of...

Chas,
Yes you are correct. 35 years of home brew must be dulling my grey matter!!!!
Thanks for your input. It all makes more sense now.

I still have not moved the m/c back to the old shed but...

Lofty,
I have a schematic that may help you. I have tried to scan it from the underside of the terminal box cover but that did not work too well.

I need to redraw it for my own records so if you...

Michael,
Hub and tooth width are 0.75" and the bore is 1.000".
As stated earlier, I think the gear is 12DP giving an OD of 10.75".

Bill.

Finally got back to this job.....
The MCB in the new shed is a Merlin Gerin 3 pole C32N 6KA 16A. So, this translates to a "C" curve 16A breaker.
From what I gather I should have a "D" curve 20A MCB...

Michael....agreed. I merely gave that OD so that a Hercus owner maight quickly check!
The bore, keyway, etc can easily be re-jigged by bushing as I have done with the old VW beetle flywheel. The...

Joe.........
First major obstacle! Yesterday I cut through what I thought was a conventional ring gear but it did not pop off as expected! It is a one piece flywheel/ring gear!!!! Those damn...

Hey Joe what a great idea.............I honestly don't think the old sloppy gear system would even notice the slight innacurracy!

Thanks.
Bill.

I have an old "New Visby" lathe probably from around the 1940's era. They had them at Sydney Tech College when I was doing my apprenticeship in the early 1960's and they were fairly ancient then. My...

Thanks very much for the diagram. That was exactly what I was after. I presently have the machine completely pulled apart for a general service. Minor rust in the steel cabinet, cleaning dust...

I still haven't got around to moving the m/c back to the old shed nor checking kA ratings of the breakers.............BUT, after reading the Hager tech bulletin on MCB's regarding inrush current to...

Chas,
Rechecked the line voltage. Ph to ph is definitely around 450-455V and phase to N is 258. 2x grid feed inverters on same system also show line voltage of 258VAC. Does seem high! But still,...

Thanks gents for the hints on "picture re-sizing". I think I've got it now so I'll try again??

The small bottle of "stabiliser" I bought cost about $19. That will treat 76 lires of fuel which works out to 25c / litre. Quite a bit more than just buying PULP which would maybe cost 5c / litre...

Ok! Mk 1 jig completed and used to re-tip 2 blades. Works much better than just placing tips by eye!!!! Yet to see how the new tips dress up and then cut.
Already a couple of shortcomings!...

Allan,
After losing the second set of teeth I thought that there must have been a nail or pin in the log but could not find anything. My guess is that one tooth came adrift and lodged in the log....

Bob, did you get a photo of the jig?
I recently lost all 6 teeth off a professionally re-tipped blade. I immediately went and re-tipped the blade myself. Not realising that fragments of the old tips...
