    Default So equitable, its almost communism :)

    OK, lets make this equitable.


    Bushmiller, I'll take your saw plate.

    Tas01, grab Simplicity's....

    All good!


    Ive a few old triangle files, so lets see how that goes. There is a Blackwoods not far from here, so there is that for more if needed.

    OK. There was a little confusion setting in there . I will send a PM to check your requirements, but perhaps wait for the sample exercise as described below.

    Just to clarify things for anybody else who is interested I can supply a bare blade (no teeth) approx 250mm X 50mm or a blade with existing rip teeth still in place, but they will probably be about 6ppi (compared to the 4½ppi of the Blackburn blade), for just a little more than postage as I have to purchase the large envelopes. If you decide to go with 6ppi a different size round file (smaller) will be required for filing the round and deepened gullets.

    If you wish to see how things go I am making up one of these kerfing blades at 4½ppi at the moment and will be filing in the enlarged gullet. I am timing the process so I can identify how much time is reasonably involved. The blades have a "patina" on them but this cleans off (or not, as you wish). I will be documenting this too.

    Regards
    Paul

    Much appreciated.

    On top of making a bow saw blade, touching up my saws (about time, never done it before...), I've now an extra reason to get those saw files.

    I was interested to see how difficult/easy this profile would be so here is a quick (not too much care taken) pictorial.

    I down loaded the 4½ppi paper template from Blackburn tools and used a 32ppi hacksaw blade (which was far from new) to cut a slot, which I estimated could be around 5mm deep. I timed each operation to get a feel of what level of effort is required and that will appear at the foot of the post.

    P1070647.jpgP1070648 (Medium).JPGP1070649 (Medium).JPG


    Then the plate was shaped to about ten strokes of the file followed by further deepening. The gullets were rounded and deepened and in two more stages the teeth were filed sharp after light jointing each time.


    P1070653 (Medium).JPG

    The plate was a bit gungy looking so I hit it with W & D. I used about half a sheet of 240g, but I used paper that had already been used for a light sanding operation and had been left out on the bench.

    P1070657 (Medium).JPGP1070660 (Medium).JPGP1070661 (Medium).JPG

    The teeth are not perfect, but I have established that such a profile is possible and it certainly looks as though it will carry more sawdust than usual. I used an 8" slim taper file (Blackburn suggested using a reg taper, but slim taper was the first I came up with out of the box and I thought "that will do".) The triangular file lasted really well and I only used one side with plenty more sharpening with this file still to go. The saw slot with the hacksaw worked very well and made life a lot easier. This technique works well for rip saws with their near vertical tooth, but its a little more fiddly for crosscut saws where it may not be practical to saw to nearly the bottom of the gullet.

    The gullets were rounded using a 5/32" chainsaw file, which also was not brand new. The trick there seemed to be to lean heavily towards the back of the tooth to the left for the first couple of strokes. After that the file followed the path already created. It took about 10 strokes to reach the bottom of the gullet. I did refine the gullets after to make them the same depth so a little time should be added to the figures below.

    I measured the saw plate thickness at .040" (1mm). It is 250mm long and 50mm deep.

    Times taken:

    Hacksaw slot to approx 5mm deep: 10mins
    First shaping with file: 15mins
    Further tooth shaping: 5 mins
    Round gullets; 12 mins
    Sharpen: 5mins
    Clean sawplate (240g only): 10 mins

    Total time: 57 mins.

    Once you factor in getting the materials together and setting up the plate in the vice I would suggest this is a two hour job.

    Regards
    Paul

    Paul, now you have to make a body/handle for it ;-)

    Great job. I was thinking of copying this profile as well when I made a kerfing saw plate for my Stanley #50, but didn't dare to. Also I used a piece of saw plate which already had a tooth pattern cut and only needed sharpening. It does clog up fast, but for smaller boards I have been resawing so far it wasn't annoying enough.

    However, now from your post I will probably make a new plate with this tooth pattern as well.

    Without ever having used a saw like this I suspect that you are right in that the standard teeth will suffice for a short board, up to a point. It is when a longer board is used that the problems occur as the sawdust has nowhere to go unlike conventional sawing which will have the blade continually clearing the sawdust burden.

    Did you get a blade sorted Ev? Or still considering a Blackburn's blade?

    Still waiting on the postie for BushMillers gift

    I'm thinking of what to do with the framesaw, but I'd say I'll get the Big Kahuna. Prob order on the 6th

    The new plague shutdown will give me time to finish my minibench! Yessss..... then I can resaw like crazy.


    BTW, I bought these Jorgensen Pony clamps in 6" and 12" to aide doing the job sizes I'm doing now. They absolutely rock! I did a glueup this week with them (Merbau again) and they have a lethal kung-fu grip! Impressed.

    EDIT - Ah POOOO..... the woodworks has suspended delivery for a bit. Bugger.

    EDIT - btw, I thought to apologise for constantly hijacking your nice thread

    Oh no so is that the same for Blackburn also or just Sydney reseller? Was thinking of placing the order soon. It's a toss up between building this saw or a cheap 14" bandsaw of equivalent cost. I'm slightly (maybe crazy) leaning towards giving the roubo saw build preference. Hmmm

    I miss my Laguna SUV14 so bad. Its in the storage, has been for 2 years

    I think the Roubo saw is an excellent choice. It is for what I want to do anyway. Hand tools seem to be working really well for me (and as you know I loved my machines!)

    The halt was at TheWoodWorks, not the Blackburn site. Balckburn advised there is a 4 week delay from order-to-post if you want them to sharpen it all for you (which I would).

    Ive watched a few videos on people using these Roubo saws with considerable competency. The rate they can resaw is terribly impressive. I wouldnt want to be doing it for any big jobs, but then again Ive never really done that anyway!

    Yes, I think I will be ordering from the USA on the 6th.

    I agree, i think once i move into the new workshop (which hasnt been identified yet) ill look into a bandsaw, but for now i just placed my order for the 4" x 48" blade along with the kerfing plane blade and bolts. this will allow me to a far greater re sawing ability than i do at the moment for a while and is trivial to move between workshops eventually instead of a bandsaw.

    The standard 4 week waiting time is now "Between a sustained surge in orders, my kids being home all day for virtual learning, and supplier delays and shortages, lead times on orders containing containing saw kits or parts are becoming lengthy. I am doing all I can to catch up, but am now running about 8-12 weeks behind. If you need parts sooner, please contact me and I will do what I can to expedite that. I apologize for any inconvenience."

    Which is fair and completely fine by me, i have been procrastinating with this purchase forever so now its done ill keep busy with plenty of other things until it arrives

    G'day mate. I'm optimistic about the kind of housing I'm after exists within your neck of the woods. It's being snapped up at the moment so I'm not going after anything serious at the moment. Still finishing up things on my current place to get it on the market first.

    Considering if I get into a rental first to help me settle to take my time looking to buy. See how the market is later in Q3 l Q4 this year

    Cheers
    Nathan
