)
and itll need the filler done.

just wondering mj, how did the B&Q putty stand up? what sort of race usage did it cover? all season? bonneville? just curious to know how well it performed in comparison to JB weld. as you probably know its been taken over by something else therefor nla. any signs of coming away etc? my 'new' cases will be in need of a suitable putty thats easy to come by, i know devcon is the 'tony montana' of the epoxy world but finding it local is a mission.

Matt - the B&Q stuff is in the Bonny engine. Done Bonny + about 3 dyno sessions.

JB Weld still available in the states brought a load back so if you want some got some spare.

Just trying some devcon titanium putty. Evil stuff - makes my eyes water I itch like hell and makes your skin burn (I was wearing nitrile gloves but the dust when rubbing it down did me).

Which is best - I still reckon JB Weld sticks like the proverbial - but it runs so difficult to shape. I use masking tape to hold it in shape.

i agree, the jb runs like hell and is pretty tricky to work with but i trust the stuff 100%, the thought of a lump breaking away dont bear thinking about.

what is the benefits of the devcon titanium putty? is it a super strong formula? sounds like the stuff to season a nice fillet steak with! i will take you up on your offer if thats ok, how much? im still intrested in the C/H but v.busy atm, will pm you.

apart from sorting out distorsion issues if the ocure is there any reason why these areas could be welded up tig or mig and fettled ,it would be always on my mind if the plastick came loose .took me a while to find this again.i was looking for another reason ,t do with back skirting

If you can sort out the distortion issues I don't see why you couldn't weld.
Having said that the filler works and as long as the surface is prepared properly I don't know of any failures with JB weld.

absolutely of course ime just thinking of costs ,id`e have to buy the compound but welding wouldnt ,and ime not a racer ,just a ladd who likes tinkering ,both does the same job ,i was sort of asking has anyone seen it done ,ie putting feelers out ,ime guessing it was quicker to do the job yersen while racing ?

JB Weld isn't expensive - certainly far cheaper than the gas and welding rods needed....

Hi Mj Whats your thoughts on Ally welding the cases, surely this gets away from the possibility of a piece breaking off. seems a bit hit or miss?
When welded it all becomes part of the case and cant fail.

Have you ever experienced a J.B Weld failure?

Cheers
Kev

I must have done 10 or 12 sets of crankcases now and I am not aware of any failures. I use the JB Weld 24 hour variety as it has a higher operating temperature. The key to success is getting a good key (pun intended) for the JB Weld to adhere to. Make sure the surface is clean (use thinners) and has been scored.
