Will it do the 42" Mathews Apex?
I was able to work on my buddies Reflex Caribou and that's a bit longer than your Apex.
Apple has a (really lousy) picture of what I believe is an Apex in an Edge. It uses a set of adjustable straps to hold the riser. If you were going to do that regularly, it would pay to make up a set of "bowstring" holders. I did that with my older E press to replace the rope that fell apart every 6 months. I used D75 to make a super 60strand string served with 62XS. The total string rating would be several hundred pounds. You would make the loops the proper size to fit the posts then slip them over the riser to anchor the bow in the press.
I bought the Edge to be able to press parallel limb bows. After replacing the chain with a 1250lb rated turnbuckle, I like it a lot. It's down side is that changing setup for different types and sizes of bows is kind of a pain. You have to make a lot of adjustments. I kept my E press to work on non-parallel limb designs, and it's MUCH faster when working on different bows, (but useless for the newer designs). To totally relax a set of limbs, I needed to add the turn buckle, the jack doesn't have sufficient travel with the (useless) chain.
All in all, it's fine for home use, but if you need to change things a lot for different bows, you might want to shell out a bit more cash for another design.
