You could try something like this

Bob

The Last SR on which I re-mounted the controller and bits-and-bobs had mountings just like these.  I thought it had to do with what it was driving as much as with the engine itself, and the varying loads as that engaged/disengaged etc - in this case a multi-stack water pump lifting water almost 100 metres vertically and with which the pump stopped/started as the water tank filled etc

To be fair, the controller was stupidly mounted on a pedestal where it would pick up all the vibes . . . .

Definitely would mount it on timber skids and bolt the timber down solid. Earlier it was noted that if bolted directly to concrete there is a possibility that the concrete may not be perfectly even and level and can cause a foot to break. I know it does as I have a leg broken off a small hit n miss engine and now I need to weld it up and then use some timber between the foot and the steel frame.

I think timber is probably the easiest and most readily available. Just be aware that unseasoned timber moves, Australian hardwood might actually move enough to crack a casting. The other issue here is termites/white ants which will turn a railway sleeper into dust in about 18 months.

So I would recommend pine treated with copper chrome arsenate, it`s strong enough to take the load, weak enough to not damage the feet on you equipment and nothing is going to eat it. You will probably need to re-torque the bolts at regular intervals as the timber dries and shrinks

I have some very decent timber slabs I have kept for such a purpose. Either for ground mounting or making a transporter.
Also had a great big log about 8 Ft long I sawed in half which took some time even with the chainsaw up at Dads.
Left it there knowing I was moving and to dry out properly.

Last time I was up there I went looking for them only to be informed they had dried out well and made great firewood.  When I said you  knew what I cut them for, Father replied well you left them there in the wood shed and I didn't think you wanted them any more.
Do you remember why they were left in the wood shed Dad?  Yes, to Dry!  >:(

Plenty of trees I can cut, but now I'll have to wait another 2 years or more to season them.

I like watching saw Milling Vids but I nearly cry when they get these massive logs and cut them into pissy little 1" boards.
 FFS, use the regular size plantation trees for boards and keep the big stuff for slabs and great hulking beams that you can't get out of many trees these days.

When I worked for Boral saw milling, it would break my heart to watch beautiful timber cut into 4" x 1" boards, it would then be sent to Lismore and Casino to be dried. After that is was turned into decking boards for verandas.  :'(

70% waste, 30% usable timber and they had to pay M I Organics to take away the waste. F*cking criminal they can`t even be bothered to recycle the waste into particle board or burn it to power their operations.

I feel for your loss of seasoned timber, it takes a year per inch thickness to air dry wood. It can be kiln dried but why use fossil fuels to do what nature does for nothing. Lack of foresight and planning as usual.  >:(

The prim and proper way to mount the engine to concrete is to place one 1/4" steel shim at the high spot to leave room for grout, them shim all the lower ones to same level so the base bears equally. Then set the engine and lightly snug the nuts, then grout under the base and finally tighten the nuts when the grout is dry and hard. This is in most of the older Lister manuals along with how to properly mix the concrete and how much is needed.  Lister was pretty thorough about how to mount their products properly.  I cheat that process by doing a good job with the concrete and use 1" hardwood boards under the engine instead of grout. Works out well if you keep after the nuts until they quit loosening.

Im going to use my railway sleepers good seasoned timber I got for bending over to lift them!

Railway sleepers are a Commodity here.
The mill down the road from my father was buying all they could get when they were replaced by concrete.
They sawed them up thin for paneling interiour walls.  Another travesty as some of this wood was over 100 years old.  They guy that owns the Mill took my father for a tour and told him they were making fortunes out the stuff. Said they were also buying all the timber from old bridges they could get which was also BIG timber in many cases and sawing that thin as paper as well.

I have seen hardwood Sleepers at a hardware chain here. Some of them aren't bad looking timber at all.
 I would like to make a transporter out of those one day.  I think if these were sanded down fine and lacqured they would come up well.

The timber I cut also had a very nice looking colour and grain to it.


I was looking at Kiln drying timber Bob.  What I found was it does not have to be all that hot.  I reckon I could make up a one off setup and feed that with an oil burner and have any timber dry in 2 Days.  If I had something like a big lump of 36" Metal Pipe that I could really fire some heat into, probably do it in one day.  I might be able to use roofing Iron sheets to form an oven and dry large timber that way.  The only problem with supplying heat would be not to go too much and turn it into a charcoal Kiln!

I saw a couple of transports made from half sawn logs that were very old and they looked great. If I could find a set of old wheels.... perfect!

There are several ways of drying timber but the most important thing is to seal the end grain before doing it. Failing to do this will result in bad splits and checks in each end of your lumber. There are a great many wax based spray on sealers available for exactly this purpose.

The second issue is that timber tends to cup, warp and twist as it dries. I stack mine with battens between them at about 400 mm centers. I then wrap the bundle with ratchet straps and torque them down tight. I tighten them on a weekly basis until the timber is dry.

The trick with successful drying isn`t heat, it is air flow. Australia is quite hot enough and dry enough to season timber very quickly. A lot of drying sheds are fan assisted.

I would avoid applying excessive amounts of heat to timber as it can break down the cellulose structure and make it weak and brittle. I have seen over kilned pine as soft as balsa wood.

Another method a lot of wood turners use is to soak your unseasoned piece of wood in ethylene glycol (antifreeze). This  forces the moisture out of the wood very quickly but makes it almost impossible to polish.

20 + years in the timer industry tells us:

Anything will do to seal the ends, but you are dead right about heat etc

Rule of thumb:  shade & battens & weights on top & ventilation but not wind & drying at the rate of an inch a year (board thickness)

Slow is best

Kiln drying is only good for production work not artisan timber

More timber guys eh? Strictly armature here. I have a Peterson swinger we play with along with most of the needed bits to turn it into projects.

I would not regard the material to be used for Mouting an engine and making a transport something that required " Artisan Timber".    :laugh: :laugh:
