It is Jack, but we still have a heap of work to do on it !
That's a great pic you put up, that is what we were after and then the wadkin came along !

Matty is that an air cylinder ? If so you might want to consider a dead man switch . Scene one or two of the CC's run auxiliary motors off of the break end of the motor for more power . These were strictly cross cuts at 90 saws . Will you be incorporating a nose guard And a dropbox ?
Imagine steel is easiest to work with and of course that metal has a reassuring strength to it . Manufactures Tended to makes it these in aluminum or brass not because of the strength but because of the fear of a spark entering the dust collection should the blade hit on the jam up. I see yours has got the short Arbour?
Jack its an after market festo air ram
Foot pedal operated and adjustable.
The switch gear needs work, emergency stops mounted close to the operator and possibly a dead mans switch, although I'd like to know more about them !
The cage surround should suffice for a nose guard and was thinking of a gap in the table for ofcuts to drop through, not sure, still rolling around some ideas ?
Jack and Bob I might be making a steel guard only because I have the tools to do so.
I don't have access to a tig welder for ally.

There'a always pop rivets :-) - have a look at this https://www.woodworkforums.com/f200/g...-issues-204634
Very tidy work Bob !
I probably could of looked at aluminum with that in mind but I already had the steel kicking around the shop.
Many thanks for all the suggestions so far, goes to show there is a few ways to skin this cat here !
Here's the progress so far ......

looking good Matty. do you take it off to change blades?
Hi Matty,
Looks good!
I take it that the few rough spots in the rim weld are deliberate camouflage, patina! They are "age defining character" sort of like grey hair and wisdom.
I like the Steampunk idea. Much better than trying to be a slave to politically correct "authenticity".
Your big blade is going to make quite the music in that guard, a bit of a resonance chamber.
At least there will never be a question of whether it's On or not.
Have fun,
Alli
Hi Alli,
Rough spots indeed, lol..!
Thats just me being lazy, stick welding is not an ideal application for this type of work, the rod when brought to the edge of the work too long basically melts every thing and has to be build up again.
Its times like this I miss my old Mig welder, I'll get it repaired soon, its just an earth problem that I can't solve, so needs to be looked at.
My Brother is a gun welder, he would say Tig on this guard, his welding is just beautiful, hot rod chassises, stainless steel you name it he can weld it.
The big blade was turned on yesterday and yes it's got some speed, made the first cut through a rather large 150 x 250 beam.
I noticed a very small drop in tone as it made the cut but it powered through.
What's going to be key I think is to maintain a sharp blade at all times, either that or modify the motor for more HP/torque and less RPM.
I noticed our Wadkin CD docker only runs at 1440, that seems a more ideal cutting speed than 2800.

Hi Matty,
I still say you should claim it as deliberate artistic character creation!:D
My brother and nephew weld like that, I just go and buy beer. Much easier.
2800 rpm, that's over 20,000' per minute with that big blade, that definitely sounds too fast. Serious business!
Have fun,
Alli
Matty I have a VFD on the one saw and am going for one on the CC mostly for the brake. I do have a 500mm blade that i run at 45 hz for thick cuts on the Delta 40C. the problem with the lower speed on the DD saws is you give up power the lower the HZ and the 5 hp is a little shy to begin with. In my research i found high speeds blades from Linbide saws
Guidelines for using Linbide Saw Blade
and there 500mm recommended speed is 90m/s max rpm is 4000.
as i said my saw has a brake and i just finished a drop box
