Coping saw plans

[Hawkeyefxr]

I am look for coping saw plans, i have looked at loads of website but they tend to scroll pattern plans.
I'm guessing the the distance for the centre beam is pretty important to tension the blade, they look to be be off centre in the height of the saw.
I would like about an 8in throat? if that the right description.
I want to go in the shed and do something, still a bit early for my shed as there is no heating and i don't want to unwrap the lathe as it is in it's winter mode at the moment (old towels that are coated in oil

cheers

Are you talking about a small frame saw?

If so, I wouldn't be at all surprised if this is something that has never had any proper drawings done, as it is just 3 (OK, 4) bits of wood plus some handles and the blade, and made up in any size you like. Here's one I found:

Cheers Mike, that will get me started. Funny enough there is no measurement for the horizontal bar position though it does look to be about 1in off centre.
Will get on this next week

I don't actually think that is the best design. I believe the shoulders of the loose M&T joints should be rounder. I made one a year or two back, so let's see if I can find a photo.

Here you go:





Those knobs were place-holders until I got access to a lathe.

Well, a classic internet-era plan from which literally dozens of successful examples have been made is the "Bugsaw". Alas, the original site is long gone and the Wayback Machine is not infallible, but the link to the PDF of plans and notes is all there. For the Woodworker's 1930's plan (with rounded tenon shoulders) listed on that page you'll need to be redirected here.

Thanks Alf, that’s a link to something else altogether lol, but very comprehensive, it’s well over half a century since I last held one, consequently I have forgotten what little I knew, and was a little surprised to read that it cuts on the push stroke, but then again depending on the handles it depends which way you pick it up!

Is bandsaw blade suitable for these saws?

 

[Mike G]

Yep. Exactly what I used. It has the benefit that you can cut it to whatever length you require.

Yes, I was surprised by that too. I've had a simple metal frame coping saw for years and never really got on with it, then one day a friend saw me using it and said I had fitted the blade the wrong way around, ie cutting on the pull stroke. I wont claim that has totally transformed things, but it is certainly a bit easier to use now.

I did wonder on the square shoulders of the MT joints and will be doing as you have shown.
I also like the like your knobs (nothing personal), they is more control using the frame.
Just need some warmer weather now.
