All the best alan

Hi Al, I bought one of theses some time ago. You will need to use the 2" length stones. I use the 3 legged large stone holder which I use in a Makita battery drill. I run the drill at medium revs and plung the honer in and out a few times. With the right combination of speed and vertical in and out action (something like counting: one-two- one-two..up-down up-down) ) I can get the cross hatching that is around the right 30 degree? angle. Quite simple to use as the shaft is flexible and allows hand guidance and no need for a drill stand....See: http://www.pvrdirect.co.uk/productinfo. ... 029...good price too.

Oh yes the radial stone pressure is variable by screwing down a threaded coller onto a pressure spring. The harder the screw is turned down the more pressure is applied outwards to the stones, so depending on how much scoring you want to remove the cut can be varied. Start with light pressure and gauge how the job is progressing...all quite easy when you are doing it.

Hi Les thanks for the info I have being on the site and orderd the VS029 honer alan

Ok Al. When you use it, don't forget to have the tool in the bore before switching on and switch off the drill before removing it, although no real damage will be done if you forget. Easiest to use if drill has variable speed trigger, so you can "soft start". Ideally, you need to have the barrel raised of the bottom of the work table with two blocks of wood so you can move the stones right down to the bottom of the bore so they emerge say 1/2" and bring the stones out of the top of the bore 1/2" as well. This will decoke & remove the upper wear ridge. You should lube the bore as well with thin oil..."3in1" is ok I find. Check progress every 10 secs, which might be enough depending on stone pressure and bore condition.

Using it in a tray of paraffin is also a good plan for evenness of cut and preservation of the grind stones.

I thought that looked an absolute bargain intially and was all set to order.
However, the real stumbling block, as these things generally are was the shipping cost.
If you live anywhere south of Edinburgh, prompt delivery is yours for a mere £3.95 ish sir, 'what's that, highlands you say? IV postcode, ah yes, right, thats the bit thats still UK mainland, doesn't involve crossing any seas or international borders, no passport control checks and the whole of which Royal Mail will deliver to for exactly the same cost as the rest of the UK!, let me just key that into the p**s taking software shipping calculator, OK, that's £19.95 sir, shall I package that up for you and take details, or shall I just insert that where you suggested right now?':D (it really does grate on me and the reason is courier companies rob businesses, they hand over, often to royal mail, in Inverness and, ahem, ...pass on the charge... plus about 200 percent loading..... to the business.
.........I ordered this anyway, £16 delivered, to anywhere in the UK, despite me being in a small highland village that can only be delivered to by specially trained stealth sheep practised in evading the local Haggis militant factions.......http://www.ebay.co.uk/itm/120894389346? ... 1439.l2649.........

Hi guys---------you might also want to consider FLEXI HONE. An American product available in this country----------have a look at this }----http://www.youtube.com/watch?v=dTqHQ5b4FAU---and also this}---- http://pacehigh.co.uk/category6767/flex-hone-reg.aspx -----I have used these professionally and can personally reccomend them. By default you cannot over pressure the cutting faces.

Problem with the flexi hone that i can see is that you need a specific unit per specific bore, ok for a shop but excess clutter and extra cost for a home mechanic, i look at it and wonder also 'what if one of the dingleberries breaks off, you've got a wire prong waiting to gouge your cylinder wall? Just my thoughts.

[Alan R]

Hi guys------- yes Mk1s, that's a good point re}--- clutter in the home-mech's garage, but based on the amount of times that our home-mech. is likely to be using either type then same could be said for the pivoted stone type as well..... It's probally more cost-effective for your local club to invest in a range of these and let all its' members have access----but then that brings with it another set of problems which I suspect we've all encountered at some time or the other? ( Getting them back, breakage etc.) ----overall you might just as well get your tame Engine/Cyl. Head shop to do it for you ??? As mentioned I've used the FLEXI-HONE on ROLLS-ROYCE Diesel engine liners (V-8's & V-12's)within the MoD (Army) over a 15 year period and no, those balls don't drop off ---honest.....Just a thought but our home-mech. will also need a method of measuring the finished bore to ensure compliance to limts of fit as well---like this}---- http://www.ebay.co.uk/itm/Silverline-6p ... --------OR THIS}-----http://www.ebay.co.uk/itm/Thomas-Mercer ... 2071?pt=UK -------------- as excessive use, especially with the rougher grades, can be detrimental.
