The worst are the contractors. They eat at 11 and at noon go shopping and do it again after 5. The other day a guy was waiting in his truck when I got done with lunch. That has not happened in 20 years, They blow the horn, ring the phone and pound on the door when you go in to eat. I and only I was raised to figure out when people have their meals and not come at that time. In the winter, after seeing nobody all morning, and taking off all the layers of clothing and sitting down for lunch some s.o.b. wants me back outside pronto.  If you wait on somebody at noon they will always come back at noon and you good customers will come at 1 o'clock and that means no lunch. If they have come long distance I will take care of them.      The joys of a home business!

You got the family right!  I will post a pic of the fruit when I get home.  The fruit is round and a little larger than a marble.  If you bite into it, it is very sour.

You can rest them on the girts if they straddle the posts. But sometimes they are in line with the posts and that creates a problem.
This added snow load from the upper roof is why we hire engineers to verify our loads and joints.

I have a sine at the top of the driveway with the hours I'm open. 1½ hours after I'm close they drive in while I'm eating my supper. ::)
The numbers are 4" tall, Do you think if I put up 8' tall OPEN 8 AM TO 4 PM they will see it.?
Anyone else has that problem?

Well, it appears that just posting on the FF asking for help is good luck!  As soon as I made my post, I found a site that would convert the military number.

Turns out it's a Bosch Rexroth valve.

I need to rebuild some of the hyrdaulic spool valves from my military crane, and although I have the military part numbers I'm having a difficult time finding parts.

Presumably this crane was built from off the shelf parts, so I'm hoping that if I know what brand it is I can contact the manufacturer to see if they can supply a rebuild kit.

Here is the logo.  Does anybody recognize it?

It's 1989 vintage manufacture.  Thanks much.

Scott

Sawmills and Milling / Equipment shed

I saw an article about building this about 8 years ago. I would read the article about once a year and kept saying I need to build this. Anyway. a large poplar blew down a year and a half ago and fit the bill. I could get a 14' clear log out of it - about 20' diameter. I milled out many 3/8" x 2" strips and completed the arches. Other than screws, glue and plastic the place is pretty cheap. My time isn't worth much! Hopefully, the plastic will last a couple of years and then I'll use something else. John is pretty happy to be under cover!

Drying and Processing / Re: Solar kiln in the tropics.

« Last post by longtime lurker on Today at 05:07:54 PM »
Wood drying in the tropics is definitely different, with pluses and minuses compared to the temperate zone. What's your weather like: wet tropical or dry tropical? Rainy season every day or a distinct season where it rains followed by a distinct dry season, because that impacts on kiln performance, particularly with solar kilns.

I'm in the wet tropics of Australia, and used to drying large tropical hardwoods. Different species but same kind of density range and sizes. Couple of pointers for you.

End sealer is your friend and you need to apply it to the ends of cut logs as soon as possible after felling the tree for it to really work. Then again later with valuable species just because its cheap and good lumber is worth the extra insurance. Water just about runs out the ends of tropical species when freshly cut but once that initial moisture is gone they will start to crack if some precautions arent taken

Generally speaking when its hot I need to slow my initial air drying rate down on 3" lumber, usually by putting the sawn timber in a place with lots of ventilation but not much airflow. If it dries too fast it develops micro checks that you cant really see but that later blow out to large cracks.

Mostly wood will go from green to 20% MC in a couple of weeks. Thats the point at which all the free water between the wood cells has ran out, and what we're left with is the water inside the cells themselves. At that point I will rotate my stacks of lumber into a place with better airflow.

I like to airdry heavier lumber like that for mostly 6-9 months to a year before going to the kilns. If it's really figured and I'm worried it will be a problem child to dry I give it longer.

Passive solar kilns like the Virginia Tech design can do well in the tropics, sometimes. Much depends on kiln design and your climate: I've seen some work and some be not so good. Here where I am they will do well in winter but not so good in summer which is our wet season.... because it's stinking hot so the kiln runs hot and pulls a lot of moisture out of the wood but the high ambient humidity means theres no-where for the moisture to go, and then a shower of rain comes over, the kiln cools and the humidity stays inside and condenses back over the wood. Down the coast from me 100 miles in the dry tropics passive solar kilns work great but need care in summer because they sometimes work too well, but that extra 100 inches of rain we get makes them a fail here for half the year.

Hybrid solar works well here.... using the sun to heat water to heat the kiln. Have a look around these guys website:  
http://www.solardry.com.au/solardry/10m.html
Friend of mine has one of those and it's a champion, however he's on top of the range so in winter he does have to use the gas boosters a bit when its frosty outside. If I had one of those here it wouldn't need that because I'm on the coast so our winters are still warm.

My own kilns are DH units. They work well, but I have an electricity bill attached to that where if I had the hybrid solar I wouldn't. One of mine is a prefabricated container based unit, the other is a little Nyle L53. Both work well.

A lot of wood has been dried here with conventional kilns. The way to avoid excessive case hardening in thicker 3" lumber is to drive the heat into them at the start of the cycle... you need to get the core temperature of the wood raised before you start pulling moisture out or you are drying the heated exterior of the lumber before the interior has a chance to catch up to let the water move. A lot of case hardening can be solved with reconditioning also.

Why 8%? Thats a dry country spec, or are you thinking of exporting?

I was imagining a larger item for some reason.

Etransfer or PayPal for payment and just use the postal service for shipping.  Canada Post will take care of the duty and HST owed when you pick up the package.  Just make sure the seller cleans it up well and doesn't leave any fuel or bar oil remaining.

Drying and Processing / Re: Solar kiln in the tropics.

« Last post by GeneWengert-WoodDoc on Today at 04:42:46 PM »
First, you did not caseharden the Peruvian walnut.  This inability to dry this species is a result of the wood itself.  You did not cause it to stop drying.  Casehardening, incidentally, is a stress situation and does not affect drying.

In answer to your questions
1.  Any MC can be put into the kiln.  But if the wood takes six months or more, drying two loads a year is uneconomical.  It is better to air dry for six months or longer and then maybe take four or six weeks in the kiln...8 to 12 loads a year.
2.  It depends on species in order to predict drying time.  If Peruvian walnut, green to 8% MC could take three years.
3.  The solar kiln needs 1 square foot of roof area, which would be nearly flat in many tropical countries, per 10 BF of lumber.  This is for 4/4, so you could use less roof area for 3” slabs.  Do this by going higher, not wider.  Making one kiln that holds 20 MBF, is likely a poor decision, as you would have to get that much lumber of the same thickness, species and initial MC.  So, stay with a kiln about 8’ wide.  Make each kiln higher but still 18’ long.
4.  Solar fans will work, but they are usually not built to last for a long time.  They are expensive for a kiln...you would need about three solar fans per 1000 BF.  Wind powered would be better...larger fans.  Electric is best.
5.  Some tropical species have special needs and frequent checks.

« Last post by Cornhusker on Today at 04:41:19 PM »
Thank you for the reply, Jim. That's exactly the kind of advice I was looking for. It does seem like the ledger would need to be quite stout.  In fact, it seems to me like the ledger would need to be even more beefy than the top plate supporting the higher, central roof, since the shed roofs have a longer span, (12' vs. 8') and the shed roofs also have to withstand snow drifts dropping onto them from the upper roof.  I'll run those calculations on ledgers and see what I get.  

But I understand that you don't recommend resting those shed rafters on the girts, correct?

Thanks so much for the illustration, too - super helpful.

Hot again today. Didn't do much surveying, but I got a bunch of machete work done on the farm. It's too hot for gearing up for brushcutting, and I wanted travel light. I think I'm actually getting somewhere with the bittersweet. It doesn't look like it, but it's all thinner, with a bunch of panic suckering. Pretty easy to cut, and easier to see, so I pulled a bunch of it up by the roots.

« Last post by btulloh on Today at 04:12:46 PM »
I looked back at your original question. Are you just trying to kill a standing tree?  Much easier to accomplish. Shallow cut around tree, apply something with triclopyr. Look up “hack and squirt”. Also look up girdling - no poison needed, just takes longer.
