One day timber framing scarf layout and cutting workshop
« on: July 16, 2013, 12:14:49 pm »
My schedule has changed and I find myself available to teach a one day scarf layout and cutting workshop here at my sawmill yard and shop.

I have a shady spot to work and this Saturday, is suppose to be nice weather.

That is Saturday the 20th of July, 2013. Start time 9am

Opening for three students. Cost $100 per person.

Each student will layout and cut two halves of a bladed scarf joint:

 

 

This joint is a great joint to use to join two plates together. Or also to use as a post repair. That is putting a new bottom on a rotted out old post.

Each student will receive a cd with the step by step instruction with pictures showing exactly how to layout and cut a bladed scarf joint, as an eBook.

Please email me at jrsawmill (at) verizon (dot) net or call 800-422-6250 for more info.

Jim Rogers

PS. eBook is available to anyone who wants one, cost is $5. This eBook as well as other timber framing eBooks are listed in my "Timber Framing Tools for Sale" in the for sale section of the FF. Commission to the forum as usual for any sales or workshop registration.

PPS: Here is one half I cut this morning:

 

 

Sign up for this workshop and learn how to cut a very useful scarf joint.

Are you extending that frame you took down with the gin pole?

Yes, that is the plan. But two post will need to be replaced so only four will need post extensions.

I figured it was a good time to teach and pass on this method that I was taught.

It works great:

 

 

You can see we have used it before. Several times.

I may have time to also teach how to cut this in a standing frame, instead of on the bench.

I got a sample done to show how it should look when finished:

 

 

The post is laying on a 2" thick plank, as a table/straight edge.

Here is a closeup-side view:

 

 

I was pretty happy with the way this one turned out.

Jim Rogers

PS. This post needs more pegs and then the stub tenon cut on the bottom end.

PPS. The reason why these posts are getting extensions is that the customer wanted a taller frame. That is more head clearance under the tie beam. When the frame is re-erected it will be 8' from the bottom of the tie beam to the finished floor.

I have just completed the Stub tenon on the bottom of the first extended post:

 

 

Now the finished sample for the workshop is complete.

Sign up now for this unique workshop and you'll learn how to do a post repair, with this bladed scarf joint.

Looks pretty cool Jim.  I think it's incredible how pieces like that can be added to old posts.  I saw some amazing examples of scarf's in Dave's binder he showed me at the TF course. 

Are those hand split shakes on the barn for siding?

Yeah, I've cut a couple of scarf joints, maybe 50 or so.. :D I think there is only 11 in this pic.



Looks good Jim. How much did you have to raise the shed?

I don't know for sure. Those were all stripped off and clapboards were put on the sides and shingles on the ends.

Here is a picture of the barn after it was restored:

 

 

The back wall that had the post bases replaced is on the left, with the white painted clapboards.

Sorry Dave I didn't see your question before. The customer wants the bottom of the tie beam to be 8' off the finished floor. So I got him to tell me what he was going to put down as a floor, in regards to thicknesses. So I could calculate the lengths of the post extensions.

From the bottom of the original post to the bottom of the extension is 18 1/4"

These short extensions are a bugger to hold on to. Every time I try and chisel a bit the thing slides all around on my workbench. I've had to get out a large bar clamp to hold it still.

This morning, in the shade, I'll be laying out a replacement post, to the full length.

Nice picture of the frame laid out in that shop.

Working on those small parts is what inspired me to build my trestle. I got tired of chasing sawhorses around the shop with some little chunk of wood clamped to them.  :D

Dave
Do you have a link to that "trestle" build?

Seems a bandmill which has the clamps and the saw would be ideal for cutting those scarfs (at least for several of the cuts). And some very accurate start/stop control would be a bonus too.

I'm not sure how practical it would be, but another option would be to cut the scarf's on a long timber, then when your done with the scarf joinery, cut the end off to the size needed, at least you'd still have the weight of the timber.

That is what is normally done. But after you cut them off then you have to fit the two halves together to get the joint to work. One piece is the long post. The extension is short and had to be trimmed slightly to fit the post. This trimming is when the clamp must be used.

But I'm giving away way too much info. You'll have to see the video when I'm done with it.
