I've used those reciprocating saws and the blade flops around all over the place. I think that you will be very disappointed with the result given your application. As you have relatively few uprights, I'd be inclined to clamp blocks to the uprights in line with your cutline and then use a normal saw. That way you (a) get support for the saw and (b) end up with a square end.

Especially as the rest of it is so very neat and accurate.

Ah I didn't know that. How about my circular saw? (trying to get away from manual work :oops: ) It's the corners will be hard work otherwise!

Very hard to hold at that angle, up there and keep square.

Just had a thought....when you say reciprocating saw I thought you might have been talking about the alligator type saw. But is it one like a Fein ? If so then you're sorted :eusa-dance: Just use the clamp/block technique to keep the blade square.

Those do have their uses but can be the very devil to keep straight cutting especially when working off the ground.
There are blades which have not only the set of the teeth but have a slower wave over several teeth. These are stiffer and don't wander as much due to the extra clearance in the kerf. Similar blades can be found for jig saws and also less prone to wander and are my goto blade of choice.

Fein is a brand not a saw type. They possibly make alligator saws as well as multi-tools to which you are referring Roger.

ok I haven't used it yet. I'm now in quandary - if I try it, I can't take it back. Don't want to try it if it's no good for the job! ie wanders off (blade flex) like a jig saw? Youtube videos of similar saws look quite good.

Trust me. Get a Fein or similar saw. Not at home so can't easily post a link. But out of all the powered hand machines I have its got me out of so many holes

They will cut straight if you can use them in a comfortable position where you can see all round and possibly shift your position, grip, stance etc to correct any wander before it gets serious but up a ladder where there are other considerations like not falling off etc :lol: then wander is more of a risk.

I class these tools more for demolition type work, removing windows even cutting round tree roots than quality construction work or a "get you out of trouble" tool.

Yes they behave very much like a jigsaw. I dont think it is possibly the tool for the job in this instance if I understand the task correctly and a cheapo NEW hardpoint saw for a few quid will serve you better.

Good Luck

Bob

PS what Roger is talking about is a multitool, now offered by several makers which is a much more controllable device albeit slower cutting.

just one example of many https://www.toolstation.com/shop/p88296

That demolition saw will never cut straight.

Think I'd try the circular saw. Make up a guide/support for the saw base so it will cut at the right distance and not need awkward holding - something you can move and clamp on. You may have to finish some cuts with a handsaw but the cut will be started and square.

I really counsel against using a circular saw. It is bulky, awkward and heavy. You are going to be trying to balance it on a piece of timber that may/may not stay clamped in place. As you enter the cut, you're trying to balance the saw, get the aim right etc ad then when you exit the cut repeat it all again. And probably up a ladder to boot.

If you can take back that saw and swap it then it will (a) be much easier and (b) give you a useful tool for later. I never ever use my alligator saw these days.

Sorry Roger, disagree with you on the circular saw. Yes some can be bulky and heavy, but get yourself one your comfortable with and do it in a couple of passes, jobs a goodun. Done similar before with studwork that's needing adjustment ie ive cocked up !

For a guide a piece of 4"x2" offcut screwed into position. I would cut it the exact length to go up against the header, not going to go anywhere. Using the same guide each time of course saves measuring. Just make sure with a bit of care you hold/push the sole plate of the circular saw onto the timber. Getting yourself into a comfortable position on a sturdy pair of steps is important. Even better a couple of trestles and some boards at just the right height so you can kneel and hold the saw with both hands - told you ive been there before !!

Or as previously mentioned your not going to go far wrong with a square and a nice new saw.

Sorry very much agree with you on the reciprocating saw tho. Mine just gets used for demo work. Do not know how you could use one with any real degree of accuracy.

Yes it was brutal & wandered but I couldn’t have used the circular saw, so it got the job done. My wife is killing me for spending too long on this and went ballistic when she found out I was taking all the header plates off to cut down the walls :cry: I did it anyway, I’m going to be looking st this for the next 10 years.

Right, hell of a day I was out there from 7.30am to 7.30pm. Got wall cut down and top plates back on, rafters on (except I’m 2 short!). So jobs a good ‘un.

Anyone help me with the roof / edges cost?

First I need if I buy plastic fascia board for all edges (probably from selco as local to me) so 4 x 5m lengths at about £24 each (so £100)

I want to buy EPDM. The cost for the rubber is only £256, well worth it. But by the time I add proper epdm 6 side pieces (kerb upstands as each one is only 2.5m long) + 2 back pieces (gutter trim), corners, glue etc it's a bit over £400. AND I am having 18mm OSB 3 board which is £245

so altogether at least £740 which to my mind is excessive mainly because of the cost of all the plastic fascia boards, kerb upstands etc which annoys me.

So is there a way I can do all the edge stuff cheaper but still use epdm and not ruin it :eusa-think:

Kerb upstands being raised edges to the EPDM to keep the water on the roof at the sides and top?

In that case, simply rip some 4x2's on the diagonal to make a triangular section, and fix these in place on top of the OSB before gluing your EPDM down.

If you can design in a fascia of some sort, maybe 4x1 timber, where you could take the EPDM down the face, under the bottom edge, and a short way up the back, then you'd have no need of the plastic trim. You'd need to mechanically fix the back edge of the EPDM. Use contact adhesive rather than the white gum adhesive for this detail.

yes for raised edges. OK I will think about that. I suppose might actually keep to 6 x 1" planed timber fascia (to keep depth same as joists) which is about £3.11 a metre so about £40 quid for all 3 sides which is lots better & I can don't mind buying proper epdm gutter trim for the back edge which will be approx £30.

As long as I can bring the epdm down and under the fascia & fix securely will be my only concern (eg keeping it tight all the way along). I can glue to side of fasica board as it comes down, and fix batten on inside edge or underside of fascia board along the length. Just thinking out loud. It's tricky cos I won't easily be able to pull up on inside edge of fascia board as the joists will be there at intervals.

anyway, ta

edit just seen your pic yes I understand. Problem is the uplift part on inside. Unless I go for 7 or 8" board but that might be crazy!

edit 2

Oh I see I hadn't thought about the fascia being mid-point along roof line I was imagining it hanging below. Thanks.

Side pieces done today and also put the cross member in across the middle, which was a bit difficult but got it done eventually. Overall took another day even though it doesn’t look like it. Trying to make the most of the good weather and make hay why the sun shines!

One of the side joists has twisted which made everything difficult, annoying as I picked the straightest ones for the edges when I installed last week.

I’ve been using various truss clips for my connections, with sheradised nails. Oh, fitted window sections too.

If I'm understanding this right... In my limited experience you don't want to be pulling the EPDM when fixing it. It is elastic and if you stretch it, it tries to return to its original size and may eventually peel. It is more like wallpapering - you spread it out onto the glue without stretching.

I didn't buy the plastic edge trim for my shed or my workshop. Both have the vertical side returns retained with screwed on battens. The battens are cut with angled top and bottom to assist run off and make a drip edge.

Spent today closing the eaves and joining the rafters to the cross member:

Took whole day! Around about 40-odd closers required, and I’m blooming knackered from being up and down the ladder all day. All nailed in place, flush with the exterior walls to make sure birds don’t rest there.
