Woodturning – timber framing cheats


Finding efficient ways to move big lumps of oak around the workshop is something we take quite seriously, especially as the consequences of not doing so are pain and discomfort, not to mention perspiration and effort. It’s not that we don’t like to build up a healthy warm sweat to keep off winter’s chill on a cold fresh morning………it’s just that sometimes, you just want an easy life!

A large part of the process of timber framing involves flipping over timbers so that we can mark and cut the underside, and then flipping them back again (endlessly). All very well with 6ft studs but not so easy with a 20ft 12″ x 10″ floor beam. Brute force will get the job done (we have the callouses and stretched arms to prove it) but so much easier with some little timber framing cheats.

We use some gigantic spanners to ease the pain, and then as soon as a mortice appears, it’s the perfect place to insert a suitable lever.

All Hands On Deck


Oak framed deck

The stonework at Parks Cottage has recently been completed which means we finally got to install the outside decking area on the south side of the newly built oak framed house

The views down the valley are mildly spectacular on the worst of days, and so when the sun is shining the 30m2 of oak framed deck area is going to be hard to resist

The frame is short and stubby, so as not to require a handrail which would disrupt the views from inside the house……we still just managed to squeeze some dinky bracing in though for stability.

Jake and I installed the chunkily joisted frame on day 1, cutting the posts on site to suit the concrete pad levels.

On day 2 we cut and fixed the dry oak decking boards with a 10mm spacing and 3″ stainless steel ring shanked nails, all piloted. Nice to do really repetitive work for a change and to give the brain a rest!

Cambridge


It’s been a blowy and wet winter so far so it was with trepidation that we closely monitored the long range weather forecast in the weeks before our latest raising on the outskirts of Cambridge. Well, we needn’t have worried as the wind piped down to the merest feathery rustle and the rain clouds dissipated repectfully overnight to be replaced with crisp, clear and sunny skies. Perfect.
Jake, Sylvain, Adam and I packed our toothbrushes, lucky underpants, tool belts and tape measures, piled into the pickup and headed East. Then we headed East some more until finally the A14 ran out of tarmac and we reached our destination in the Cambridgeshire fens
Normally we shack up in some more or less serviceable B & B but this time Rob pushed the boat out and practically hired a stately home for 2 nights! Valet parking and four poster beds would not have been out of place at Madingley Hall – check it out here to see the kind of accomodation that Rob lays on for his team.

Even managed to cram in some fly fishing and wild boar hunting with enough time for a cooked breafast before an early start on site at 7.30am.
The frame we were erecting for James and Christine makes up 2 parts of a complex newbuild with essentially two asymmetric wings connected by a tall fully vaulted oak link and walkway, which itself changes angle at the mid point. Sounds confusing? You try building it!
We began with the easy bit, the roof structure to one of the wings, comprising 4 x raised collar trusses with purlins, ridge, windbracing and wallplate. So far so good and by 11am we were enjoying a well earned break.

The truss feet (principal rafters) were unusually designed to fit directly onto padstones in the blockwork wall.

Although our structural engineer stipulated supplementary metalwork within the collar joint to resist the added tension forces.

After this point things started to get more complicated as we assembled and lifted into place the 2 massive trusses that defined the link space. Once these had been braced and supported with “scabbing” (any timbers that are used to temporarily stabilize a frame) we were able to install the connecting walkway posts and rails and finally secure the roof with the purlins and ridge. Phew!
By 4.30 we were able to send the crane home and retire to Madingley Hall for a freshen up before some Castle Ring Oak Frame team bonding in Cambridge. Ended up in the Pint Shop which was recommended by John the builder – you might be impressed (or not) by the drinks menu which includes about 80 types of gin http://pintshop.co.uk/menus/drinks.pdf
Naturally we tried them all for research purposes.
Wednesday morning was again a biffer of a day and we enjoyed pegging up the frame, fixing down the ridges and purlins and tidying up before piling back into the truck back to Wales.
Thank you Cambridge

Building a roof under cover of a ….. roof‏!


Yes, it’s been unseasonably warm, but it’s also been seasonably wet!

We’re thankful we haven’t had to endure anything on a par with Cumbria but close inspection of our feet reveals we are beginning to notice the appearance of webbing between the toes.

We’re grateful to have a warm and dry workshop to float about in and thankfully it’s just big enough to accommodate our latest project, a large, shallow pitched, hipped roof which is to be part of a new build home near Swansea

We can’t get the whole thing in and up in one go so we’ve broken it down into 3 sections for practical purposes

There’s quite a bit of tricky joinery to work out, framing up the “dragon ties”, “hips” and heavy 6″ x 4″ jack rafters, but it makes much more sense to be getting this done in the warm and dry with the advantage of the gantry and block and tackle, rather than on site in the wind and rain

How are we going to get it out the workshop?

Local frames are fun‏


It’s always nice to put up an oak frame locally.

For starters it means you can stay in bed a bit longer before setting off in the morning, but one of the main benefits is that the pressure is off when it comes to remembering all the crucial bits and bobs you need for the raising. Don’t get me wrong, you still need the same bits and bobs, but if you forget something, being able to pop home 5 miles away is a real luxury. Jake forgot his hair gel and moisturiser when we were in Hampshire last, and very upset he was too!

Our latest frame went up in Shobdon a few days ago and comprised a single storey exposed oak frame onto a split level stone plinth, with plenty of glass mixed with insulated cedar clad infill panels. The raised height stone plinth is to cater for kitchen work surfaces, and at the same time serves to break up the horizontal lines. Clients Duncan and Lorna have decided to expose the roof trusses, purlins and ridge, opting for softwood rafters with an internal plasterboard finish.

A perfectly still, dry October day was the setting for the raising and as you can see Duncan and Lorna joined in the fun, not only plying us with homemade cake and bacon butties, but also lending a hand with the frame assembly.

Where oak frames are exposed externally as well as internally, careful detailing is crucial to avoid future weatherproofing problems. Strategic grooves are machined into the frame before it is assembled to allow for the insertion of water shedding DPC, along with lead drips on all horizontal members. It makes for a rather painstaking and fiddly frame raising process, but still, we managed to get the final ridge beam up just before the warm glow of the autumnal sun disappeared over the horizon.

Come and build your own oak frame!‏


A few months ago you may remember we travelled down to Essex to add a complicated oak framed extension to an existing cottage for clients Richard and Abby. The raising day had been inked in, cranes, lorries and hotels booked, only for some stormy weather (the remains of a Caribbean hurricane apparently) to scuttle in accross the Atlantic.

There was to be no escape or shelter from the wind, especially as the cottage was on the site of an old windmill, and sure enough we had no choice but to postpone everything until hurricane Mabel (can’t remember what she was called but that will have to do) had blown over. Putting up an oak frame is hard enough without the added excitement of hanging onto wildly swinging timbers 30 feet up in the air.

Everything went smoothly, as I hope you can see from the photos, and Richard (who works in construction) and friendly neighbour Jerry mucked in wholeheartedly with the raising. Indeed, one of the highlights of the trip was the sight of Richard “adjusting” an existing dormer window to make room for the new oak frame with a………… chainsaw!

A few weeks earlier we had been able to witness at first hand Richard’s enthusiastic approach and more refined carpentry skills. At Richard’s request, he came and spent a day with us in the workshop getting to know his frame and actually making some of it! Along with sweeping up sawdust and making the tea, we had him scribing and chiseling out joist pockets for the floor layout.

Drilling Holes


One of the countless ways we manage to turn timber into sawdust or shavings is by drilling holes in it. These are so that different timbers can be joined together using offset oak pegs (a process called “drawboring” – see this previous blog on the subject). Most of the holes we drill are either 25mm (1 inch) or 19mm (3/4 inch) depending on the size of peg required for the forces within the joint, for example whether it is in compression or under tension. All when and good so far ………the tricky bit is being able to drill the hole vertically, through a piece of oak that might be a foot deep. If, using a long auger bit, you get the angle wrong to start with, there is no way to correct it, and it might emerge half way towards the next parish. Not good. That is why all timber framers display a “concentrating” “serious” face when drilling…

Trestles or “Saw Ponies”‏


Essential beast of burden for all timber framers, the “saw pony” (or trestle, as some pedants like to call them) is a critical part of the workshop setup.

Most oak framers lay out the frames horizontally at a sensible working height so that the top surface of the frame (the face) is flush and level. Having a substantial herd of readily accessible ponies is therefore imperative on larger frames to support all the lumpy bits of oak. It goes without saying then that the physiological characteristics of the saw pony have to be carefully selected – it needs 4 (seems obvious I know) sturdy slightly splayed legs to form a steady and resolute base, and a rock solid straight back that can comfortably support over a ton of weight for long periods of time.

Temperament is another important area where the saw pony must be carefully selected. Standing still for days in a hot and dusty environment is not going to suit the more flighty and wild members of the breed. At Castle Ring we have a rigorous selection policy and reject those ponies who demonstrate capricious and impetuous behaviour. We want boring workhorses, not frivolous fancy dans!

Currently we have a herd of over 60 ponies all of which have been sired by the splendid stallion, Balthazar the Third, who spends his days grazing serenely in the ancient monument.

Tree Planting


We’ve been planting trees for the last few days in the glorious weather – a mixture of native broadleaves, oak, cherry, beech, with scattered field maple, crab apple and aspen at the margins, on the southerly slope looking down over the Walton Basin.
It’s the last 3 acres of planting to be done at Castle Ring. We started in 1999 and have clocked up well over 40,000 now. All with the same trusty spade and dodgy back. Amazing to think that even though we have 36 acres, we’ve probably walked on every square inch now.
We flushed out a fox who scarpered off down the valley in a huff, have witnessed lots of lazy ladybirds resting before summer action, and note that the buzzards are beginning to circle overhead, no doubt hoping that we keel over soon in the heat……….

We might not be around to see the trees come to maturity but hopefully someone will benefit.
