Bargain Jewellers saw

[D_W]

If you have the German type shown in this thread, affix the blade first, then grab the back of the frame and put the excess spine against the bench and lean on the saw with one hand while tightening the top screw with the other. Make sure you tighten the top firmly or it'll just slip.

Regular fretsaws have very little tension.

David

Ah it is the available tension then. Thank you.
When I have needed more tension on the fret saw I just shorten the blade. Or sometimes the blade shortens itself.

David, I do not like the tone of my reply. It is me thinking out loud trying to persuade myself not to spend money. I apologise, Thank you for taking time to answer.

XY no worries! I think there is a nomenclature problem here.

Fretsaw implies fretwork or Marquetry to me. These fretsaws have something like 15" throats. This being the reason why high tension is not available.

The model shown is a Jewellers saw, used for cutting thin metal sheet, as well as other things. For this work high blade tension is very desirable.

The expensive Knew concept saws take outstanding tension, and seem to have been welcomed by many woodworkers for sawing the waste on small dovetails. When dovetails are very large, the coping saw comes into its own.

Best wishes,
David

 

[That would work]

Does it have an abrafile blade in it?
(Which seem difficult to come by now)

14 .024″ / 0.61mm .067″ / 1.70mm 16 Per Inch / 6 Per cm

Not really woodworking sizes, but I have used the coarser ones for coping ogee skirtings - it takes a minute or two longer, but the fit is perfect. The drawback is that the blade doesn't swivel like a coping saw's.
Without the higher tension they snap before you can blink.
(I usually use 3/0s for silver.)

David C, Thank you.
I have learnt a great deal this afternoon, mainly from the Knew Concepts web site, where they compare the blade tension in various frame saws. Their larger Marquetry saw is eye-wateringly expensive, but seems to have all bases covered.

Wow...$2500. Not something I thought I'd ever see.

 

[xy mosian]

Definitely not an un-considered purchase I think. The best part in that saw, for me, has to be the bungy cord. As new, and good as the saw is, still the 'old' ways (used to be a bit of nicker elastic) have a place.

I wonder if AvE will get enough patrons to review it.

D_W,
I'm sorry I do not understand AvE.

AvE is a youtube tool review channel that really tells you about the tool. Bloody good too
