guillotine blades

[johnakay]

the blades in my guillotine(hand operated) about 9" in length.
seem a bit soft and worn, it still cut's but not cleanly.
I've sharpened them my self but it need a bit more off.
and I don't like the idea of putting a grinder to them.
I usually use a good file, I think it will take a bit more than that.
I foolishly cut some 8mm and 10mm bright round bar and it took the edge off.
is there any where I could get these resharpened and hardened.

try some local engineering company's some might have a surface grinder that could possibly do the job , i'm not a machinist tho so i couldn't guarantee it would work .

Perhaps check out Machine Mart , Screwfix or on the internet to see if a replacement set is cheaper.

Not being funny .. is it really a guillotine type cutter or is it a set of bench shears ? I ask for nine inch blades does seem rather small for a guillotine .

It should be far too hard to sharpen with a file - that seems to be the root cause of your problem. Get a local engineering company to make one from something like gauge plate or oil hardening steel, shape it, harden and temper it, then grind it to sharp.

ok a bench shearer.
I made it myself and the blades are from my old work place about 30 years ago.
where it start to cut there was a small gap this would make it hard to cut so the blades were scrapped due to wearing beyond the limit.hence making my own using these blades.
they lasted well.
by the the Time I fanny on getting it hardened/sharpen.
it would be easier to buy one like this one which I'm considering

John if you look on the MM web site there cps200 (which looks similar to the sealey) has next to the lower blade bolts are some grub screws that are used to adjust the lower blade (I have very similar one) the grub screws are used to adjust the blade contact from frount to back and would take out the gap you have on your made up one. If you have made yours like the sealey (which I notice does NOT have the grub screws) you could try adding them or failing that you could shim the blade to remove the gap. Also the hole in the top blade of the sealey and clarke are for cutting bar up to about 1/2 or 3/8? not sure as only cut up to 5/16 (8mm) bar with mine. Hope that all makes sense!

I already have adjusting bolts in my old one. blades need hardening as well as sharpening.
I've gone and bought the sealy one now. once I get that I will drill and tap out holes etc for adjusting screw's. thanks any way. john
