Piston Ring Compressor

I've done many with these and have had no problems. Just go slow and easy. You can feel if one catches and you just stop and re-fit things.
I agree, even with a proper spreader I worry about them breaking.
I don't understand, I don't usually put pistons in from the bottom.
I have done lots of automotive small and big blocks.
Look in the phone book for mac tool dealers and phone them. it should not be that expensive. Most of your automotive stores will have this style which is what I have and It will do from your motor bike to a diesel truck piston

Making the ARP-style compressor would appear to be a trivial task for a good machinist.
Putting plastic tubing over the rod bolts helps prevent crank damage.

Tube sleeves on the bolts are minimum mandatory protection. Add a sock over the end of the rod to avoid any bore scratching.

I've used the ribbon style 4x myself, no issues.
I usually soak the piston & ring lands (already ring'd) in about 1" of oil before putting them into the compressor, where oil is dripping off & rings/lands are 100% soaked in oil. Clamp the compressor down while shifting so that the bottom of the compressor is just below the oil scraper ring (last ring down), & square on the piston. Oil the new bearing in the rod & crank journal once more.
Sit atop of the bore and slide down until the compressor touches the block. Push down slightly on the compressor as you gently tap the piston down with something soft, like the wood handle of a hammer, rubber mallet. If it binds, give it a few taps with slightly more pressure (maybe 50%), but no more.
If it wont' go down, a ring has caught, & you need to pull up & repeat the process.

Just ordered 2x 100mm and 2x 104mm Wiseco's from http://www.accu-products.com. Should be easy to modify one of each size for +0.5mm 1st oversize piston.

I've had limited access to the Internet / RL these past few days, so my apologies for the slow reply, but I wanted to thank everyone for adding their thoughts and experiences here. Its been really helpful to hear what you've all used, and learn some of the tips that helped in installing the pistons.
The links to the manufacturers / suppliers of the ring compressors were also a huge help / time saver...I settled on a Wiseco 100mm sleeve in the end - it seemed the simplest / safest way to go for the moment, and at $30 not a substantial investment.
BTW, can anyone confirm the required ring gap range for the '87+ engines. My WSM offers nothing, and I only found one mention on RL, but I'm not sure what year it pertains to. Gaps stated were:
Compression Rings: 0.20-0.40mm
Scraper Rings: 0.40-0.90mm
Thanks!

Resurrecting a thread here...
Are there any updated thoughts/ recs on a ring compressor?
I am looking a this style, it seems the most idiot-proof..

QUESTION: What is the best way/location to measure the bore for selecting the correct compressor?
Thanks !

4.7 is a 95mm bore, right?

Yes sir, 97...
I think the only thing that has ever tried to bore out these cylinders is DIRT!
Asking in order to confirm my sizes, and also from a general education standpoint... I really don't know very much,I don't want to kill my car.... and I have very little shame in asking simple questions
Thanks,
Dan

Also, I just got a 100mm Wiseco compressor from Rally Sport Direct. I think they're a Subaru shop, but they carry all of the sizes. Decent price and quick shipping.

Thanks HWY
I'll check those out tonight
