An EX21 Question - Scroll Saw Woodworking & Crafts Message Board

JohnB · 05-07-2008, 12:15 AM

G'day all,
I finally did some "real" scroll work on the Excalibur, and boy does it make cutting bevels easy, with the table staying level and the machine tilting

BUT!!! Can someone please tell me what the back to front movement of the blade should be. It seems excessive. When placing a block against the back of the blade and moving it through it's full stroke the block is pushed 2mm away from the blade. I was having trouble cutting nice corners, and was cursing myself.

Is there any way to minimise this movement?

Thanks all.

I am not sure what the movement should be but I imagine it is the same as old Yella since the blade pivot mechanism is the same.
I havent done a bevel cut yet so I can hardly wait.

John,

Got this off the net:

Hegner is 0.006"
Delta Q3 is 0.024"
RBI and Excalibur is 0.026"
DeWalt is 0.030"
RBI in the aggressive setting is 0.047
Delta P20 Yet to be tested.

Tom

Hi John: Yes, there is a way to minimize the movement you mentioned. I had a long talk with Ray at Seyco this morning and he walked me through several processes that got my EX-21 purring like a kitten. Way too long a process to go through here, but if you're interested let me know and we can exchange email on the subject. The only tools needed are a couple of allen head wrenches and a 7/16" wrench.

COuld I take you up on that offer too Ajay?

JohnB · 05-08-2008, 11:06 AM

G'day Ajay,
Thanks heaps mate.
I don't feel so much like an empty beer bottle in a brewery now.

It worked, and I'm now becoming a happy Ex-21 owner.

ajay · 05-08-2008, 11:43 AM

Glad to hear that John. Happy scrolling.

ajay · 05-08-2008, 11:45 AM

Hi Carl - Just sent you a PM with instructions.

Pajaro · 05-08-2008, 12:55 PM

Ajay would you send me the Info on the movement adjustment also. My ex-21 may be a little out sorts too...
Thanks.

JohnB · 05-08-2008, 02:05 PM

G'day Tom,
Thanks for the info.
I used Ajay's instructions and a dial gauge. I have it pretty damn close to those tolerances.

You're a pearler mate
