Thread: Odd addition to your Fp1 universal table

I discovered a very useful accessory to add to your Fp1 universal table when doing unusual compound angles. It was made by Yuasa and it allows you to dial in the angles. It would be nice if the universal tables on the old FP1 could also be cranked into position. Picture of setup attached.

****** Now before you start yacking about the unsafe 5 inch cutter being unsupported, remember that the overarm can't be used in this situation. Which brings up an idea maybe some of you have addressed.

Have any of you put risers and extensions on the overarm so you can support larger cutters in the horizontal mode?

No - I just bought a stub arbor to do exactly what you are doing. I got some saws from Boeing at $5 a piece but wasn't watching the diameter.

If it isn't cantilevered out too far I don't see what the problem would be. The overarm is more needed for wide "slabbing" mills with a heavy cut.

You mean that you don't have an overarm riser with the coordinated support bearing spacer? Oh Herr, Singer...

I made a new overarm for my FP1 by machining a dovetail in a piece of plate, welding it to a piece of rectangular tube, that acted as a spacer, then welding a second tube on top that extended out to the front of the machine, to this I added a drop plate to take the front bearing. All the tubes were filled with concrete and the whole cleaned uop, filled and painted, I can use 8" cutters.

I have an overarm that has been "modified" to accept a larger cutter. Mine was done a little roughly, but it's actually not a bad idea. At some point I intend to clean it up a bit so it looks a bit more "factory". Not much material has to be removed to take a decent sized slitting saw, and the overarm would not be appreciably weakened. I can hear the purists gasping in horror

OK Guys- let's see the pics of the extended and modified overarms.

Ross- Are you pulling my chain ? Yu mean there is a factory original??? :&gt

Markus:
Well i think one could use the riser from the boring head to get the overarm higher from the spindle. The tailstock would be another question. I have never seen in any book a riser setup for the overarm. But there is plenty that Deckel made that i haven't seen. There is a riser for the dividing head that is part of the punch milling outfit to allow work on larger parts. Also avaliable is the mating tailstock, the one that has the fitting to mount the vernier calipers.

Hey Ross- good idea using the boring head riser. I'll have to remember that. I think a tailstock extender will have to be a future project.

By the way, do you know of any tailstocks for a spiral milling head laying around???
