Cast Iron Fence for FD 250
Posted: Tue Jun 26, 2018 11:17 pm
Howdy gents,
This forum needs a new thread to bring back a bit of life. I've yet to divert people back over here, sorry for that it's been difficult to break away from the work and working on these machines to get them tip top, or whatever the realistic equivalent is.
I decided to put an add-on to the Felder slot mortiser which allows the machine to hold square chisels. This add-on features a part that bolts onto the motor, for holding chisels, and rack and pinion assembly for driving the chisel.
Only one problem, the chisel is going to apply force to a workpiece which will be held by an overhead clamp. The chisel likely will move the workpiece and so I'll have to clamp on a backup bar each time I use the machine. This seems kind of lame, so I decided it was time for a more complicated solution.
I ordered slabs of cast iron from McMaster Carr along with a hardware such as control handles, heavy washers, roll pins and set screws.
The fence need not keep perfectly square to the table, since the stop at the front of the machine squares stock to the table, however I wanted it to be pretty close incase it should be needed to serve that function. This fence would now act as a backup in conjunction with the eccentric clamp.
A fews hours in machine work later, followed by some touch up details by hand and then blackening for a finish.
The two holes bored through the fence are set to hold the next step in this project; an auxiliary fence. I plan next to source aluminum extrusions (thanks Chris, for the referral to 8020) and aluminum plate to create a wide fence which will double as a support for long stock. The fence will feature stops which will make repeated runs a bit easier and I'm debating a support for the outrigger which will help for when I load this machine up for timber work or other large work.
