alright i will put you out of yews misery..........i have bought a..........

Qualters&Smith.large flatbed linishing machine....cast iron construction with screw holes so i can make and fit a tilting guide table........it weighs about 130lbs..and that is just the belt head...have to get hold of a 2HP motor to run it..............i rekon it is late 1930's...i will take it apart and check / clean the bearings on the rollers or replace them.....the adjusters look like the track tensioners on a D2 caterpillar tractor:lol:...........

it might have been used for knife making or flatterning off machined parts and faces............but as it is so built like a tank it means there is no flex and i will be able to cut very precice angles

should pick it up in the next few days...........

A must have piece of kit for any budding knife maker, what size are the belts?

There’s a big demand for hand made knifes, could be a nice little earner.

 

 

Do you have a furnace with temp control?

 belts are 36" X 4".............no furnace yet...........will make a flower pot (big pot) furnace bottom draught.....i wont be forging to begin with just hardening and tempering with magnet and by coulour....just need to make some quality blades first before i go all artistic..:lol:.........forging will come later

That should do the job nicely and you can sharpen all your kitchen knifes as well, in fact you could offer a knife sharpen service to the village.

 

The only problem with an open forge is controlling the heat (around 800c for five/ten minutes) of course in the old days it was all done by eye, yes you can use a magnet to tell when its reached its ideal quenching heat but the margin for error is very small when trying to hold the tempter at 800c, with the possibility of a burn to the surface structure, having said that I have hardened lots of GFS in an open hearth and tempered using the colour method with very good results.  

If you wanted to get a bit more accurate with temp and hold you could use a cheap "K" type thermocouple in the forge…..https://www.banggood.com/DT1311-K-Type-Thermometer-Ceramic-Probe-Forge-Crucible-Kiln-CR-8-p-1246850.html?gmcCountry=GB&currency=GBP&createTmp=1&utm_source=googleshopping&utm_medium=cpc_elc&utm_content=zouzou&utm_campaign=pla-uk-ele-pc&gclid=EAIaIQobChMInIK859Tw2AIVqLftCh2HhgVTEAYYAiABEgKJr_D_BwE&cur_warehouse=CN

I'll have a look in the workshop. I have a virtually new motor but don't know the output without looking.   Can deliver as far as Stamford if it fits your needs and we can haggle a price.

Love old bits of machinery like that, my old lathe is probably as old, not near as accurate now as it should be but still turns down bits as I need them. Paid hundred notes for it.
