2008.12.14 - UPDATE! - PARTS GATHERING FOR THE HYDRO-BENDER CONVERSION...
Hello All!
Thanks for being patient... this time of year is always a bit crazy at work, and with the holidays approaching there's even more to keep me distracted.
I was able to steal enough time yesterday to sit down and spend a LOT of quality time with my
www.SurplusCenter.com catalog and spec-out a complete conversion for my ProTools 105HD Bender. I've paid my dues bending tube manually, and since I don't really have room to bolt the bender to the floor in my shop, I decided it was time to finally do the conversion to hydraulic and put the whole setup on a nice compact mobile cart!
There was quite a bit of available reading on the topic (Pirate4x4, OFN, etc), unfortunately most of the links to part numbers (Northern Tool website) were obsolete, so simply copying someone else's parts list wouldn't work. Plus, I'd read a few instances where Northern Tool was careless with their packaging and had damaged powerpaks in shipment to customers. I don't need that hassle (or delay) so I decided to try a different vendor.
Here's the quick summary of the main items I ordered yesterday:
SPX PowerPack (2HP, 115V, 1.3GPM, 2500PSI) - $389.
Prince Hydraulics 3" x 24" Double-Acting Ram - $175.
Prince Hydraulics RD-2575-T4-ESA1 DA Valve - $ 75.
Misc Hydraulic Hoses (36" & 24" lengths) - $ 38.
Lots of Adapters to convert SAE to NPT ends - $ 40-ish
Pressure Gauge to observe PSI while bending -$ 17.
All tolled, the order came to just over $800 with shipping (almost 130 Lbs!) and with any luck it will all arrive just before the Christmas holiday. That will give me time to lay everything out and finalize my design for the cart and mounting scheme....
This isn't the sexiest update, but it's been on my mind as an unresolved project for a LONG time. It probably took me 3 hours to identify the proper 3-way, 4-port valve, and it took a lot of careful planning to map out exactly which fittings were needed to make each hose mate correctly with the ram, powerpack and valve. Some are SAE 6, some are SAE 8, some are 1/2" NPT, some are 3/4" NPT. I hate coming up short for parts, and I hate ending up with fittings that have the wrong ends on them...or having to use 2 or more adapters on a single fitting because I didn't plan properly. Where possible, I also bought swiveling style fittings...the hope is that I will be able to keep the hoses more tidy by being able to position them more accurately before snugging down the fittings.
That's all for now. Based on what most people here in the Northeast are dealing with these last few days, I'm just grateful to have electricity and heat (and an internet connection) to get this thread updated!
