I honed the Gard'n Mast'r Jr. engine from 3.010 to 3.020 with a Lisle hone today.

I ridge ream first to get the old piston out. I measure the bore with a telescoping inside mic(9 places). If I can take it to +0.010 then I use the hone. Otherwise it gets put aside until I learn how to use my boring bar(3 engines waiting). My last thing is my fine stoned glaze breaker with lots of WD40and then a thorough washing of the entire block and a light oiling of all machined surfaces. The hone works best when it is set up in a drillpress.
Sounds like you are ready for your own valve grinding set. I've seen them pretty cheap on CL. I bought an old Souix valve grinder for $140 that is in nice shape and a Souix seat grinder for $200. They save money and time each time I use them. Going to and from the machine shop takes more time than doing the work.
I want to get a crankshaft polisher to use on my lathe. I've actually got the tool post grinder but I don't think that it is big enough to grind a crank. Please post more pics of your shop. Its nice to see others doing this work. Good Luck, Rick

I would like to get a valve grinding set up at some point, but I'll wait for a great deal to come along. For now, the valves can be found cheap enough so I've been buying new ones and it's working out ok. My buddy with the valve and valve seat grinding is only 15 minutes away, but it would still be nice to have my own. My shop consists of my small shed, the back or front deck, or the coffee table in the living room, and the bathroom comes in handy for hot water and a place to scrub the blocks down after honing, LOL! Eventually I'll put a good size garage up so I can work like a human being and not a neanderthal. All in good time I guess. Here's a pic of the stones after I finished honing and cleaned them.

Those Lisle hones sure do a nice job, and you do a nice job making them work as well!

I will have to look into one of those hones, I messed up an engine block last year trying to hone .006 out of after a friend machined it size to size for me. live and learn I guess. that engine looks great. I have used diesel fuel for lubrication in the past, it is a trick I got from an old machinist at work that seems to work very well. keeps the stones and bore clean while you are honing.
I just got the engine block for dads b-10 back from the shop yesterday and I thought the guy took good care of me. he checked the bore and honed it then did both valve seats and the exhaust valve, when he checked the intake it was bent so I need to replace that. then cleaned the block and got it ready for rebuild all for $60. can really beat that.

Good to hear you got the block back Pete, and 60 bucks was a good deal. Sometimes even new valves can be bent or need to be refaced right out of the box. I haven't had that problem yet,but check the new valve to be on the safe side. I waited until I could find one of those hones to come up for sale new, but cheaper than they normally sell for. I just want to be able to do the work that I need to do myself. Today I'm installing the valve guide inserts. I reamed out the exhaust valve guide last night and it didn't take long.
Interesting thread, btw how do you check valves to verify straightness.

Classic, thanks for the info about the valves. I forgot to ask you how did you power the Lisle hone you used? It looks like a useful tool.
