Just wondering if those stands on ebay **LINK** are a direct copy of the old Irvine test stands or are they a bit bigger ?

Have bought from him. The blocks are alloy and so is the base. While running my NGH 35 the base cracked. I wrote back to the seller. He offered to send me one in thicker gauge alloy or steel. I choose steel and the stand has been going good ever since

I've got one of these, but having tried to fit several engines in it, I found I had to make a paxolin plate for each engine before I could mount them. Rather defeats the object.

I knocked one up out of a set of Wot 4 engine mounts but its a pain to change over for different engines, I thought one of these would solve the problem sad

You can see from the pic below the sort of problem I experienced. Here my SC 30 FS can't be mounted properly because the cam cover is fouling the cramping bar, even though I filed a taper on the corner in an effort to make it work.

I still use my Davies Charlton test stand which takes all my engines up to ,61s. Even my old JB ATOMS which have webs for radial mounting. A picture of stand appears on this page----https://www.google.co.uk/search?q=davies+charlton+engine+test+stand&tbm=isch&tbo=u&source=univ&sa=X&ved=0ahUKEwiDx8j1sZrbAhXjCsAKHfY4BCEQsAQIOg&biw=1092&bih=490

All I use is an offcut of constructional 3/4" ply with a slot cut out to fit the engine. Fit some appropriate woodscrews to retain the engine. The ply is screwed to the top of my cheap folding workbench. A couple of screws to retain a tank, pushrod held on by a zip tie or two on the tank. A fresh slot takes about two minutes to make. Never really seen the need for a fancy test stand if I'm honest.

I think there's a credit due to the guy who posted this and put himself up for ridicule in the hope it would be a lesson to others. It takes a brave man to do that.

Two screws would have saved this.

My other half would have gone bonkers, the thought of glow fuel on the woodwork. She gets wound up when it drips on the dining room table blush I nearly set fire to the small spare bedroom frown I need a shed yes

I made a copy of this type of test stand and found it fiddly to mount the engines. I modified mine by counterboring the holes in the bottom blocks for about 1/2in, then fitted suitable short springs in the counterbores. It works well and can hold the blocks in any position without having to constantly adjust the screws. Modolit
